Ceramides 0-8 transferrin Mus musculus 16-18 22336588-11 2012 The lysosomal accumulation of ceramides delivered by Tf-liposomes initiates the permeabilization of the lysosomal membranes required for the release of lysosomal cathepsins into the cytoplasm and initiation of the cancer cell apoptosis both in vitro and in vivo. Ceramides 30-39 transferrin Mus musculus 53-55 22890197-1 2012 Recent studies demonstrate that rapid translocation of the acid sphingomyelinase (ASM), a lysosomal hydrolase, to the outer leaflet of the cell membrane and concomitant release of ceramide constitute a common cellular signaling cascade to various stimuli including CD95 ligation, UV-irradiation, bacterial and viral infections.

Ceramides 180-188 sphingomyelin phosphodiesterase 1 Homo sapiens 82-85 23052231-10 2012 CONCLUSION: Based on these data we conclude that ceramide-induced Nox2-mediated oxidative stress couples mitochondrial dysfunction to loss in cell viability in the pancreatic beta-cell. Ceramides 49-57 cytochrome b-245 beta chain Rattus norvegicus 66-70 22890197-1 2012 Recent studies demonstrate that rapid translocation of the acid sphingomyelinase (ASM), a lysosomal hydrolase, to the outer leaflet of the cell membrane and concomitant release of ceramide constitute a common cellular signaling cascade to various stimuli including CD95 ligation, UV-irradiation, bacterial and viral infections.

Ceramides 207-215 sphingomyelin phosphodiesterase 1 Homo sapiens 186-189 22590738-2 2012 As the ASM is a key enzyme of the sphingolipid exchange, in the present study we have investigated the effect of an ASM inhibitor imipramine on the ceramide and sphingomyelin content in the tissues of old rats.

Ceramides 148-156 H19, imprinted maternally expressed transcript (non-protein coding) Rattus norvegicus 116-119 21932365-2 2012 The proinflammatory cytokine tumor necrosis factor-alpha (TNFalpha) elicits the formation of the bioactive ceramide by stimulating the hydrolysis of the membrane lipid sphingomyelin by sphingomyelinase activities. Ceramides 107-115 tumor necrosis factor Homo sapiens 29-56 22297646-4 2012 The rationale is that insulin resistance dysregulates lipid metabolism and promotes ceramide accumulation, and thereby increases inflammation and stress. Ceramides 84-92 insulin Homo sapiens 22-29 22337830-1 2012 Ceramides are lipid signaling molecules that cause cytotoxicity and cell death mediated by insulin resistance, inflammation, and endoplasmic reticulum (ER) stress. Ceramides 0-9 insulin Homo sapiens 91-98 22337830-2 2012 However, insulin resistance dysregulates lipid metabolism, which promotes ceramide accumulation with attendant inflammation and ER stress. Ceramides 74-82 insulin Homo sapiens 9-16 22337830-5 2012 Mechanistically, we propose that toxic ceramides generated in extra-CNS tissues (e.g., liver) get released into peripheral blood, and subsequently transit across the blood-brain barrier into the brain where they induce brain insulin resistance, inflammation, and cell death (extrinsic pathway). Ceramides 39-48 insulin Homo sapiens 225-232 22337830-7 2012 The end result is increased ER stress and ceramide generation, which exacerbate brain insulin resistance, cell death, myelin degeneration, and neuroinflammation. Ceramides 42-50 insulin Homo sapiens 86-93 22942738-11 2012 Altogether, our data strongly indicate that the inhibition of ceramide conversion to complex sphingolipids by D609 is accompanied by an enhancement of FasL-induced caspase-dependent and -independent cell death in T lymphocytes. Ceramides 62-70 Fas ligand Homo sapiens 151-155 22258513-7 2012 To explore the mechanisms underlying this dysregulation, we evaluated the expression of four genes connected to ceramide metabolism: ASMase, NSMase 2, GALC, and UGCG.

Ceramides 112-120 UDP-glucose ceramide glucosyltransferase Homo sapiens 161-165 21932365-2 2012 The proinflammatory cytokine tumor necrosis factor-alpha (TNFalpha) elicits the formation of the bioactive ceramide by stimulating the hydrolysis of the membrane lipid sphingomyelin by sphingomyelinase activities. Ceramides 107-115 tumor necrosis factor Homo sapiens 58-66 21932365-4 2012 We demonstrated in SH-SY5Y human neuroblastoma cells and primary cortical neurons that TNFalpha is a potent stimulator of Mg(2+) -dependent neutral sphingomyelinase (Mg(2+) -nSMase) activity, and sphingomyelin hydrolysis, rather than de novo synthesis, was the predominant source of ceramide increases. Ceramides 283-291 tumor necrosis factor Homo sapiens 87-95 21932365-6 2012 Notably, TNFalpha provoked an NOX-dependent oxidative damage to sphingosine kinase-1, which generates sphingosine-1-phosphate, a ceramide metabolite associated with neurite outgrowth. Ceramides 129-137 tumor necrosis factor Homo sapiens 9-17 21932365-6 2012 Notably, TNFalpha provoked an NOX-dependent oxidative damage to sphingosine kinase-1, which generates sphingosine-1-phosphate, a ceramide metabolite associated with neurite outgrowth. Ceramides 129-137 sphingosine kinase 1 Homo sapiens 64-84 21932365-8 2012 Blunting ceramide and ROS formation both rescued sphingosine kinase-1 activity and neurite outgrowth. Ceramides 9-17 sphingosine kinase 1 Homo sapiens 49-69 21932365-9 2012 Our studies suggest that TNFalpha-mediated activation of Mg(2+) -nSMase and NOX in neuronal cells not only produced the neurotoxic intermediates ceramide and ROS but also directly antagonized neuronal survival mechanisms, thus accelerating neurodegeneration.

Ceramides 100-108 insulin Homo sapiens 30-37 17219404-8 2007 In summary, palmitate appears to cause insulin resistance in children"s myotubes via its metabolism to ceramide, and this process appears unrelated to IMCL formation and is ameliorated by oleate. Ceramides 103-111 insulin Homo sapiens 39-46 17210985-3 2007 Our results indicate that the antibody (rabbit IgG) specifically recognizes ceramide in lipid overlay assays and detects ceramide species with different fatty acid chain lengths that include C2, C8, C16, C18, C20, and C24.

Ceramides 256-264 AKT serine/threonine kinase 1 Homo sapiens 31-34 10427136-9 1999 We propose that an enhanced capacity to glycosylate ceramide as evidenced in MCF-7-AdrR cells, is a molecular determinant of drug resistance, particularly as regards resistance to ceramide-enhancing agents such as anthracyclines, ionizing radiation, and tumor necrosis factor-alpha. Ceramides 52-60 tumor necrosis factor Homo sapiens 254-281 10465274-1 1999 We have recently reported that insulin-like growth factor (IGF)-binding protein-3 (IGFBP-3) can significantly increase ceramide-induced apoptosis in an Hs578T breast carcinoma cell line in an IGF-independent manner. Ceramides 119-127 insulin like growth factor binding protein 3 Homo sapiens 31-81 10465274-1 1999 We have recently reported that insulin-like growth factor (IGF)-binding protein-3 (IGFBP-3) can significantly increase ceramide-induced apoptosis in an Hs578T breast carcinoma cell line in an IGF-independent manner.

Ceramides 132-140 transferrin Homo sapiens 144-155 10510471-0 1999 Potentiation by vitamin D analogs of TNFalpha and ceramide-induced apoptosis in MCF-7 cells is associated with activation of cytosolic phospholipase A2.

Ceramides 148-156 phospholipase A2 group IVA Homo sapiens 104-109 10510471-9 1999 These results suggest that TNFalpha and vitamin D analogs share a common pathway leading to apoptosis involving cPLA2 activation and/or ceramide generation. Ceramides 136-144 tumor necrosis factor Homo sapiens 27-35 10454518-7 1999 In parallel trials, the lethal actions of ceramide (but not of sphingosine) were markedly diminished by pretreatment with diferuloylmethane or expression of TAM-67, confirming the effectiveness of these interventions in suppression of SAPK/AP1-dependent apoptosis. Ceramides 42-50 mitogen-activated protein kinase 9 Homo sapiens 235-239 10469329-6 1999 Most importantly, the analysis of ceramide subpopulations revealed that the total amount of ceramide 2 was elevated in keratin 10-deficient mice, whereas ceramides 1, 3, 4, and 5 were decreased among total stratum corneum lipids. Ceramides 92-100 keratin 10 Mus musculus 119-129 10536997-7 1999 Augmentation of DNA synthesis by natural ceramides was more pronounced in tumor necrosis factor alpha (TNFalpha)-sensitive 28-4 cells than in less sensitive 24-2 cells, and TNFalpha-induced proliferation of 28-4 cells was suppressed by the concomitant addition of natural ceramides. Ceramides 41-50 tumor necrosis factor Mus musculus 74-101 10536997-7 1999 Augmentation of DNA synthesis by natural ceramides was more pronounced in tumor necrosis factor alpha (TNFalpha)-sensitive 28-4 cells than in less sensitive 24-2 cells, and TNFalpha-induced proliferation of 28-4 cells was suppressed by the concomitant addition of natural ceramides.

Ceramides 272-281 tumor necrosis factor Mus musculus 173-181 10536997-9 1999 Our study suggests that ceramide modulation of T cell proliferation depends on the TNFalpha sensitivity and activation level of T cells and that SPC also has a mitogenic potential for T cells. Ceramides 24-32 tumor necrosis factor Mus musculus 83-91 10454518-7 1999 In parallel trials, the lethal actions of ceramide (but not of sphingosine) were markedly diminished by pretreatment with diferuloylmethane or expression of TAM-67, confirming the effectiveness of these interventions in suppression of SAPK/AP1-dependent apoptosis. Ceramides 42-50 Jun proto-oncogene, AP-1 transcription factor subunit Homo sapiens 240-243 10438532-5 1999 The apoptotic effect of TNF-alpha in HL-60 and the transfectants was abrogated by fumonisin, an inhibitor of ceramide generation, and by the peptide Ac-YVAD-BoMK, an inhibitor of caspase-1 and -4. Ceramides 109-117 tumor necrosis factor Homo sapiens 24-33 10446195-0 1999 Ceramide generation is sufficient to account for the inhibition of the insulin-stimulated PKB pathway in C2C12 skeletal muscle cells pretreated with palmitate. Ceramides 0-8 thymoma viral proto-oncogene 1 Mus musculus 90-93 10446195-6 1999 Ceramide, a derivative of palmitate, has recently been associated with similar inhibition of PKB, and here, ceramide levels were found to be elevated 2-fold in palmitate-treated C2C12 cells. Ceramides 0-8 thymoma viral proto-oncogene 1 Mus musculus 93-96 10446195-7 1999 Incubation of C2C12 cells with ceramide closely reproduced the effects of palmitate, leading to inhibition of glycogen synthesis and PKB and to stimulation of MAP kinase. Ceramides 31-39 thymoma viral proto-oncogene 1 Mus musculus 133-136 10446195-8 1999 We conclude that palmitate-induced insulin resistance occurs by a mechanism distinct from that of unsaturated FFAs, and involves elevation of ceramide by de novo synthesis, leading to PKB inhibition without affecting IRS-1 function. Ceramides 142-150 thymoma viral proto-oncogene 1 Mus musculus 184-187 10438532-6 1999 Supplementing HL-525 cells with exogenous ceramides bypassed the PKC-beta deficiency and induced apoptosis, which was also restrained by the caspase-1 and -4 inhibitor. Ceramides 42-51 caspase 1 Homo sapiens 141-157 10438532-8 1999 We suggest that TNF-alpha-induced apoptosis involves PKC-beta and then ceramide and, in turn, caspase-1 and/or -4, whereas anti-Fas mAb-induced apoptosis utilizes reactive oxygen intermediates and, in turn, caspase-3 and/or -7.

Ceramides 33-41 epidermal growth factor Homo sapiens 0-23 10413587-4 1999 Using IGF-IR-positive fibroblasts we demonstrate here for the first time that ceramide is capable of activating a tyrosine kinase which acts at the level of the IGF-IR to increase cell death. Ceramides 78-86 insulin-like growth factor I receptor Mus musculus 6-12 10413587-4 1999 Using IGF-IR-positive fibroblasts we demonstrate here for the first time that ceramide is capable of activating a tyrosine kinase which acts at the level of the IGF-IR to increase cell death. Ceramides 78-86 insulin-like growth factor I receptor Mus musculus 161-167 10413587-6 1999 Although the identity of this protein is not known, we speculate that it may link into the Raf kinase signaling pathway; indeed, inhibitors of MEKK reduce ceramide-induced apoptosis, thus substantiating this theory [1, 2]. Ceramides 155-163 mitogen-activated protein kinase kinase kinase 1 Mus musculus 143-147 10413587-8 1999 Finally, the potential hydrolysis of ceramide to sphingosine-1-phosphate was not the cause of increased MAP kinase activation, substantiating the role of an IGF-IR interacting tyrosine kinase, which may be involved in apoptosis.

Ceramides 199-207 FA complementation group B Homo sapiens 97-100 10395296-0 1999 Epidermal growth factor inhibits ceramide-induced apoptosis and lowers ceramide levels in primary placental trophoblasts. Ceramides 71-79 epidermal growth factor Homo sapiens 0-23 10395296-6 1999 Neutral sphingomyelinase also increased ceramide levels but did not induce apoptosis. Ceramides 40-48 sphingomyelin phosphodiesterase 2 Homo sapiens 0-24 10395296-7 1999 Treatment with EGF alone decreased cellular ceramide levels. Ceramides 44-52 epidermal growth factor Homo sapiens 15-18 10395296-11 1999 These results implicate sphingolipids as important mediators in trophoblast apoptosis and suggest that the antiapoptotic properties of EGF can in part be explained by its control of ceramide concentrations in trophoblasts. Ceramides 182-190 epidermal growth factor Homo sapiens 135-138 10404391-9 1999 Several lines of evidence suggest that TNF alpha activates transcription factor nuclear factor-kappa B (NF kappa B) through activation of protein kinase C (PKC) or the hydrolysis of sphingomyelin to ceramide in a number of cell types. Ceramides 199-207 tumor necrosis factor Rattus norvegicus 39-48 10404391-11 1999 Similarly, hydrolysis of sphingomyelin to ceramide, but not activation of PKC, resulted in an increased in IRF-1 mRNA levels in FRTL-5 cells. Ceramides 42-50 interferon regulatory factor 1 Rattus norvegicus 107-112 10409693-12 1999 These data suggest that PA functions as a specific regulator of PP1 and may reverse or counteract those effects of ceramide that are mediated by PP1, such as apoptosis and retinoblastoma gene product dephosphorylation.

Ceramides 264-272 superoxide dismutase 2 Homo sapiens 61-66 10428046-9 1999 However, stimulation of ceramide-mediated DNA fragmentation by antisense knockdown of MnSOD suggests that induction of MnSOD by ceramide is a protective response of the cell. Ceramides 24-32 superoxide dismutase 2 Homo sapiens 86-91 10428046-9 1999 However, stimulation of ceramide-mediated DNA fragmentation by antisense knockdown of MnSOD suggests that induction of MnSOD by ceramide is a protective response of the cell.

Ceramides 15-23 heat shock protein family A (Hsp70) member 4 Homo sapiens 118-123 10340476-7 1999 These data strongly suggest that hsp70 functions as a regulator of apoptosis downstream of ceramide.

Ceramides 190-198 SRC proto-oncogene, non-receptor tyrosine kinase Homo sapiens 385-388 9756500-8 1998 In summary, we found that 1) the maintenance of sustained contraction is dependent on extracellular Ca2+; 2) ceramide activates a nonreceptor tyrosine kinase pathway through activation of pp60(src) and PI 3-kinase; and 3) the converging signals are probably through activation of MAP kinase.

Ceramides 0-8 interleukin 1 alpha Homo sapiens 24-67 9797556-1 1998 OBJECTIVES: To examine the effects of ceramide, which is a lipid second messenger of cell surface receptors, including tumour necrosis factor alpha (TNF alpha), interleukin 1 (IL1), and Fas receptors, on rheumatoid arthritis (RA) synovial cells. Ceramides 38-46 tumor necrosis factor Homo sapiens 149-158 9686602-2 1998 Both PMA and the cell-permeable ceramide, C2-ceramide, caused differentiation of U937 cells, but with distinct cell morphology and CD11b/CD14 surface expression. Ceramides 32-40 CD14 molecule Homo sapiens 137-141 9681467-4 1998 However, treatment of PC12 cells with C2-ceramide, an analogue of ceramide, the endogenous product produced by the activity of p75NTR-activated sphingomyelinase, mimicked the effects of NGF on cell morphology and stimulation of both APP mRNA levels and APP secretion. Ceramides 41-49 nerve growth factor receptor Rattus norvegicus 127-133 9681439-2 1998 Because ceramide is also able to induce NGF secretion and because TNF alpha is a known agonist of the sphingomyelin (SPM)-ceramide pathway, we investigated whether the TNF alpha-induced NGF secretion by primary astrocytes is mediated by ceramide. Ceramides 8-16 nerve growth factor Rattus norvegicus 40-43 9681439-4 1998 In marked contrast, inhibition of MAPK counteracted the NGF secretion induced by ceramide. Ceramides 81-89 nerve growth factor Rattus norvegicus 56-59 9657974-2 1998 Binding of tumour necrosis factor (TNF) to its 55 kDa receptor (TR55) leads to the generation of ceramide through activation of either acid or neutral sphingomyelinase (A/N-SMase) as well as to potent activation of SAPK/JNK. Ceramides 97-105 tumor necrosis factor Mus musculus 11-33 9681439-9 1998 Altogether, our data strongly suggest that TNF alpha-mediated up-regulation of NGF occurs independently of ceramide generation.

Ceramides 107-115 colony stimulating factor 2 Homo sapiens 163-169 9657740-10 1998 Because ceramide has been shown to affect PKCalpha subcellular distribution, these data implicate a role for ceramide in mediating the rapid postirradiation translocation and inhibition of PKCalpha in TF-1 cells not rescued from apoptosis by GM-CSF. Ceramides 8-16 protein kinase C alpha Homo sapiens 42-50 9657740-10 1998 Because ceramide has been shown to affect PKCalpha subcellular distribution, these data implicate a role for ceramide in mediating the rapid postirradiation translocation and inhibition of PKCalpha in TF-1 cells not rescued from apoptosis by GM-CSF. Ceramides 109-117 protein kinase C alpha Homo sapiens 189-197 9657740-10 1998 Because ceramide has been shown to affect PKCalpha subcellular distribution, these data implicate a role for ceramide in mediating the rapid postirradiation translocation and inhibition of PKCalpha in TF-1 cells not rescued from apoptosis by GM-CSF. Ceramides 109-117 colony stimulating factor 2 Homo sapiens 242-248 9651362-6 1998 Preceding apoptosis is a TNF-alpha-induced increase in neuronal ceramide levels. Ceramides 64-72 tumor necrosis factor Homo sapiens 25-34 9651377-10 1998 Together, these data indicate that involucrin, envoplakin, periplakin, and possibly other structural proteins serve as substrates for the attachment of ceramides by ester linkages to the CE for barrier function in human epidermis. Ceramides 152-161 involucrin Homo sapiens 35-45 9651377-10 1998 Together, these data indicate that involucrin, envoplakin, periplakin, and possibly other structural proteins serve as substrates for the attachment of ceramides by ester linkages to the CE for barrier function in human epidermis. Ceramides 152-161 envoplakin Homo sapiens 47-57 9642282-4 1998 Cells expressing constitutive HSP72 were shown to have significantly reduced levels of apoptosis after heat, TNFalpha, and ceramide but not after ionizing radiation.

Ceramides 0-8 nerve growth factor Rattus norvegicus 44-63 9648862-5 1998 Treatment of PC12 cells with ceramide resulted in a time-dependent increase in JNK activity. Ceramides 29-37 mitogen-activated protein kinase 8 Rattus norvegicus 79-82 9648862-8 1998 These results indicate that ceramide-induced JNK activation is an early event and may be required for the expression of essential components of the apoptotic machinery. Ceramides 28-36 mitogen-activated protein kinase 8 Rattus norvegicus 45-48 9648862-9 1998 It is anticipated that neurotrophic factors inhibit ceramide-induced apoptosis by affecting signaling events downstream of JNK activation. Ceramides 52-60 mitogen-activated protein kinase 8 Rattus norvegicus 123-126 9648886-8 1998 Furthermore, cell-permeable ceramide acted synergistically with the neurotrophin family, which has been previously shown to support Purkinje cell survival. Ceramides 28-36 brain derived neurotrophic factor Homo sapiens 68-80 9679455-2 1998 We have shown that photodynamic treatment (PDT), using the phthalocyanine photosensitizer Pc 4 (HOSiPcOSi[CH3]2[CH2]3N[CH3]2), causes increased ceramide generation and subsequent induction of apoptosis in L5178Y-R (LY-R) mouse lymphoma cells.

Ceramides 23-31 tumor necrosis factor Bos taurus 48-75 9632721-1 1998 Cytokines, including tumor necrosis factor-alpha (TNF-alpha), may elicit cytotoxic response through the sphingomyelin-ceramide signal transduction pathway by activation of sphingomyelinases and the subsequent release of ceramide: the universal lipid second messenger. Ceramides 118-126 tumor necrosis factor Bos taurus 21-48 9632721-1 1998 Cytokines, including tumor necrosis factor-alpha (TNF-alpha), may elicit cytotoxic response through the sphingomyelin-ceramide signal transduction pathway by activation of sphingomyelinases and the subsequent release of ceramide: the universal lipid second messenger.

Ceramides 146-154 tumor necrosis factor Bos taurus 60-69 9632721-4 1998 TNF-alpha/CHX-mediated ceramide production apparently is not a result of sphingomyelin hydrolysis because sphingomyelin content does not decrease in this death paradigm. Ceramides 23-31 tumor necrosis factor Bos taurus 0-9 9632721-6 1998 However, addition of fumonisin B1, a selective ceramide synthase inhibitor, attenuated TNF-alpha/CHX-induced intracellular ceramide elevation and BCEC death. Ceramides 47-55 tumor necrosis factor Bos taurus 87-96 9632721-8 1998 Our results show, for the first time, that ceramide derived from de novo synthesis is an alternative mechanism to sphingomyelin hydrolysis in the BCEC death process initiated by TNF-alpha/CHX.

Ceramides 77-85 thymoma viral proto-oncogene 1 Mus musculus 14-17 9632728-3 1998 We investigated the possibility that ceramide may decrease antiapoptotic signaling in cells by inhibiting Akt kinase activity. Ceramides 37-45 thymoma viral proto-oncogene 1 Mus musculus 106-109 9632728-5 1998 These results are consistent with decreased Akt kinase activity being involved in the apoptotic effects of ceramide. Ceramides 107-115 thymoma viral proto-oncogene 1 Mus musculus 44-47 9632728-6 1998 This possibility is further supported by studies showing that constitutively active Akt kinase decreases C2-ceramide-induced death of HMN1 cells as well as COS-7 cells. Ceramides 108-116 thymoma viral proto-oncogene 1 Mus musculus 84-87 9632728-9 1998 In sum, our results suggest that inhibition of the key antiapoptotic kinase, Akt, may play an important role in ceramide-induced apoptosis.

Ceramides 191-199 Fas cell surface death receptor Homo sapiens 118-122 9305864-1 1997 Ceramide is a lipid second messenger that mediates the effects of tumor necrosis factor alpha and other agents on cell growth and differentiation. Ceramides 0-8 tumor necrosis factor Homo sapiens 66-93 9305864-2 1997 Ceramide is believed to act via activation of protein phosphatase, proline-directed protein kinase, or protein kinase C.

Ceramides 184-192 patchy fur Mus musculus 140-143 9252342-3 1997 Moreover, cell-permeable ceramide mimicked LPS/PAF in triggering arachidonate mobilization in these cells. Ceramides 25-33 patchy fur Mus musculus 47-50 9252342-4 1997 LPS/PAF-induced ceramide synthesis did not result from sphingomyelinase activation but from increased de novo synthesis. Ceramides 16-24 patchy fur Mus musculus 4-7 9252342-5 1997 Participation of this pathway in arachidonate signaling was detected since fumonisin B1, an inhibitor of de novo ceramide synthesis, was able to inhibit the LPS/PAF-induced response.

Ceramides 63-71 mitogen-activated protein kinase 8 Homo sapiens 84-87 9207149-2 1997 Here, we demonstrate that ceramide, a lipid metabolite synthesized upon Fas receptor ligation, inhibits n-K+ channel activity and induces a tyrosine phosphorylation of the Kv1.3 protein in Jurkat T lymphocytes. Ceramides 26-34 potassium voltage-gated channel subfamily A member 3 Homo sapiens 172-177 9292957-11 1997 We conclude that proinflammatory cytokines inhibit D1 expression and activity in FRTL-5 cells, in part, by activation of sphingomyelinase and PLA2 that results in (1) competitive inhibition of D1 activity by the enzymatic products ceramide and arachidonic acid and (2) reduction of D1 mRNA stability by protein synthesis-dependent mechanisms. Ceramides 231-239 phospholipase A2 group IB Rattus norvegicus 142-146 9206994-10 1997 Although Bcl-2 is a highly efficient inhibitor of mitochondrial alterations (large amplitude swelling + DeltaPsim collapse + release of AIF) induced by prooxidants or cytosols from ceramide-treated cells, it has no effect on the ICE-induced mitochondrial PT and AIF release.

Ceramides 147-155 LCK proto-oncogene, Src family tyrosine kinase Homo sapiens 107-113 9207084-6 1997 We also determined in the same system that, when utilizing the DAGK assay, increased phosphorylation of substrates that comigrated with ceramide standards was apparent but that this effect was due to an enhancement of DAGK activity rather than increases in levels of cellular ceramides as substrates per se. Ceramides 136-144 diacylglycerol kinase alpha Homo sapiens 63-67 9207084-6 1997 We also determined in the same system that, when utilizing the DAGK assay, increased phosphorylation of substrates that comigrated with ceramide standards was apparent but that this effect was due to an enhancement of DAGK activity rather than increases in levels of cellular ceramides as substrates per se. Ceramides 276-285 diacylglycerol kinase alpha Homo sapiens 63-67 9207149-4 1997 Because genetic deficiency of p56lck or inhibition of Src-like tyrosine kinases by herbimycin A prevented ceramide-mediated n-K+ channel inhibition and tyrosine phosphorylation, we propose a ceramide-initiated activation of p56lck resulting in tyrosine phosphorylation and inhibition of the n-K+ channel protein. Ceramides 106-114 LCK proto-oncogene, Src family tyrosine kinase Homo sapiens 30-36 9207149-4 1997 Because genetic deficiency of p56lck or inhibition of Src-like tyrosine kinases by herbimycin A prevented ceramide-mediated n-K+ channel inhibition and tyrosine phosphorylation, we propose a ceramide-initiated activation of p56lck resulting in tyrosine phosphorylation and inhibition of the n-K+ channel protein. Ceramides 106-114 LCK proto-oncogene, Src family tyrosine kinase Homo sapiens 224-230 9207149-4 1997 Because genetic deficiency of p56lck or inhibition of Src-like tyrosine kinases by herbimycin A prevented ceramide-mediated n-K+ channel inhibition and tyrosine phosphorylation, we propose a ceramide-initiated activation of p56lck resulting in tyrosine phosphorylation and inhibition of the n-K+ channel protein.

Ceramides 70-78 coagulation factor II, thrombin Homo sapiens 0-15 9240970-2 1997 Treatment of U937 and HL-60 cells with 0.5-1 microM of the chemotherapeutic drug daunorubicin induced a greater than 30% activation of neutral sphingomyelinase activity within 4-10 min with concomitant sphingomyelin hydrolysis and ceramide generation. Ceramides 231-239 sphingomyelin phosphodiesterase 2 Homo sapiens 135-159 9240970-3 1997 DNA fragmentation and the classical morphological features of apoptosis were observed within 4-6 h. Pretreatment of cells with the serine protease inhibitors N-tosyl-L-phenylalanyl chloromethyl ketone (20 microM) or dichloroisocoumarin (20 microM) for 30 min inhibited daunorubicin-induced neutral sphingomyelinase activation, sphingomyelin hydrolysis, ceramide generation, and apoptosis. Ceramides 353-361 coagulation factor II, thrombin Homo sapiens 131-146 9240970-7 1997 These results suggest that inhibitors of serine proteases can act upstream of ceramide in drug-triggered apoptosis and that neutral sphingomyelinase activation is either directly or indirectly serine protease dependent. Ceramides 78-86 coagulation factor II, thrombin Homo sapiens 41-56 9204210-5 1997 As observed for SV40-transformed fibroblasts from Farber disease, degradation of radioactive glucosylceramide or low density lipoprotein-associated radiolabelled sphingomyelin by the prosaposin-deficient cells in situ showed a clear impairment in the turnover of lysosomal ceramide. Ceramides 101-109 prosaposin Homo sapiens 183-193 9204210-6 1997 Ceramide storage in prosaposin-deficient cells was also demonstrated by ceramide mass determination. Ceramides 0-8 prosaposin Homo sapiens 20-30 9204210-6 1997 Ceramide storage in prosaposin-deficient cells was also demonstrated by ceramide mass determination. Ceramides 72-80 prosaposin Homo sapiens 20-30 9204210-7 1997 In contrast to acid ceramidase deficient cells, both the accumulation of ceramide and the reduced in vitro activity of acid ceramidase in cells from prosaposin deficiency could be corrected by addition of purified saposin D. The data confirm that prosaposin is required for lysosomal ceramide degradation, but not for sphingomyelin turnover. Ceramides 284-292 prosaposin Homo sapiens 149-159 9182681-0 1997 Mice genetically hyporesponsive to lipopolysaccharide (LPS) exhibit a defect in endocytic uptake of LPS and ceramide.

Ceramides 50-58 toll-like receptor 4 Mus musculus 8-11 9182681-14 1997 These results show that cells deficient in responses to LPS exhibit defective vesicular transport of LPS and ceramide and point to a role for vesicular transport in responses to these mediators. Ceramides 109-117 toll-like receptor 4 Mus musculus 56-59 9202042-0 1997 Phospholipase A2 is necessary for tumor necrosis factor alpha-induced ceramide generation in L929 cells.

Ceramides 68-76 phospholipase A2, group IVA (cytosolic, calcium-dependent) Mus musculus 40-45 9202042-2 1997 In L929 cells, the addition of TNFalpha resulted in the release of arachidonate, which was followed by a prolonged accumulation of ceramide occurring over 5-12 h and reaching 250% over base line. Ceramides 131-139 tumor necrosis factor Mus musculus 31-39 9202042-8 1997 The introduction of the cPLA2 gene into C12 cells resulted in partial restoration of TNFalpha-induced arachidonate release, ceramide accumulation, and cytotoxicity. Ceramides 124-132 phospholipase A2, group IVA (cytosolic, calcium-dependent) Mus musculus 24-29 9202042-9 1997 This study suggests that cPLA2 is a necessary component in the pathways leading to ceramide accumulation and cell death.

Ceramides 54-62 nuclear factor kappa B subunit 1 Homo sapiens 119-128 9195956-5 1997 Several lines of evidence presented here suggest that ceramide generated in response to TNFalpha or Fas activation is not involved in NF-kappaB activation. Ceramides 54-62 tumor necrosis factor Homo sapiens 88-96 9195956-7 1997 (ii) Ceramide treatment of cells inhibited phorbol ester-induced activation of NF-kappaB.

Ceramides 106-114 Fas cell surface death receptor Homo sapiens 63-68 9195956-11 1997 (vi) Ceramide generation in response to Fas activation was inhibited by N-acetyltyrosinylvalinylalanylaspartyl chloromethyl ketone, a peptide inhibitor of interleukin-1beta-converting enzyme-like proteases, whereas TNFalpha-induced NF-kappaB activation was unaffected by the inhibitor. Ceramides 5-13 tumor necrosis factor Homo sapiens 215-223 9195956-11 1997 (vi) Ceramide generation in response to Fas activation was inhibited by N-acetyltyrosinylvalinylalanylaspartyl chloromethyl ketone, a peptide inhibitor of interleukin-1beta-converting enzyme-like proteases, whereas TNFalpha-induced NF-kappaB activation was unaffected by the inhibitor. Ceramides 5-13 nuclear factor kappa B subunit 1 Homo sapiens 232-241 9195956-12 1997 These results show that ceramide accumulation belongs selectively to the apoptotic pathway(s) induced by cytokines, and, if anything, ceramide may participate in negative feedback regulation of NF-kappaB. Ceramides 134-142 nuclear factor kappa B subunit 1 Homo sapiens 194-203 9210401-12 1997 These results suggest that the inhibition of c-Myc and ODC expression may be early events in the response of leukaemia cells to ceramide. Ceramides 128-136 myelocytomatosis oncogene Mus musculus 47-50 9210401-12 1997 These results suggest that the inhibition of c-Myc and ODC expression may be early events in the response of leukaemia cells to ceramide.

Ceramides 103-111 ceramide transporter 1 Homo sapiens 19-23 24569996-9 2014 These results demonstrate that the phosphorylation of CERT at the FFAT motif-adjacent serine affected its affinity for VAP, which may regulate the inter-organelle trafficking of ceramide in response to the perturbation of cellular sphingomyelin and/or other sphingolipids.

Ceramides 14-22 adiponectin, C1Q and collagen domain containing Mus musculus 0-3 24606127-11 2014 These findings are consistent with the model that maternal ADN limits fetal growth mediated by activation of placental PPARalpha and ceramide synthesis, which inhibits placental insulin signaling and amino acid transport, resulting in reduced fetal nutrient availability.

Ceramides 128-136 carnitine palmitoyltransferase 1C Homo sapiens 93-98 24753742-7 2014 Since we have shown, previously, that activation of N-SMAse in MgD leads to synthesis and release of ceramide in cardiovascular tissues and cells, we believe this pathway, most likely, helps to result in downregulation of telomerase, upregulation of transcription factors (e.g., p53; NF-kB), cytokine release, mutations, transformations, and dysfunctional growth seen in the cardiac and vascular cells observed in the normal aging process, atherogenesis, hypertension, and cardiac failure.

Ceramides 123-131 protein kinase C, delta Mus musculus 110-118 24632809-3 2014 This in turn promoted cellular proliferation by activating PLD1 expression and subsequent AKT phosphorylation, which eventually resulted in suppressed ceramide generation and apoptosis. Ceramides 151-159 phospholipase D1 Mus musculus 59-63 24632809-4 2014 On the other hand, B16F10 melanoma tumors preferentially blocked the expression of PKCdelta isotype, which otherwise could exhibit antagonistic effects on PKCalpha-PLD1-AKT signaling and rendered B16F10 cells more sensitive to apoptosis via generating ceramide and subsequently triggering caspase pathway. Ceramides 252-260 protein kinase C, delta Mus musculus 83-91 24632809-5 2014 Hence our data suggested a reciprocal PKC signaling operational in B16F10 melanoma cells, which regulates ceramide generation and provide important clues to target melanoma cancer by manipulating the PKCdelta-ceramide axis.

Ceramides 77-85 AKT serine/threonine kinase 1 Homo sapiens 54-57 24079644-10 2014 In conclusion, the cell responses to ceramide are modulated by an intricate cross-talk between Akt signaling and sphingolipid metabolites, and profoundly modified by previous cigarette smoke exposure, which selects for an apoptosis-resistant phenotype. Ceramides 37-45 AKT serine/threonine kinase 1 Homo sapiens 95-98 24586752-4 2014 We found that the ceramide metabolite sphingosine-1-phosphate (S1P) stimulated the production of inflammatory mediators such as TNF-alpha and IL-8 from three-dimensionally cultured human primary keratinocytes (termed "3D keratinocytes"), which form a stratum corneum.
