Tetradecanoylphorbol Acetate 119-155 mitogen-activated protein kinase kinase 7 Homo sapiens 267-299 23833248-8 2013 However, while pharmacological inhibition of PKC suppressed PMA-induced activation of MEK-ERK-IKK signaling, activation by palmitate was upheld, suggesting that DAG-sensitive PKC and RKIP were dispensable for palmitate"s proinflammatory action. Tetradecanoylphorbol Acetate 60-63 mitogen-activated protein kinase kinase 7 Homo sapiens 86-89 23775084-5 2013 We show that both chemical suppression and siRNA silencing of PP2Ac in T-cells resulted in sustained phosphorylation of MEK and ERK following stimulation with phorbol 12-myristate 13-acetate and ionomycin. Tetradecanoylphorbol Acetate 159-190 mitogen-activated protein kinase kinase 7 Homo sapiens 120-123 23786520-3 2013 Herein, it was investigated whether 1 and three other flavonoids [chrysin (2), apigenin (3), and tricetin (4)] blocked 12-O-tetradecanoylphorbol 13-acetate (TPA)-triggered induction of CD families, which were induced through the activation of protein kinase C (PKC), mitogen-activated protein kinase (MEK)/extracellular signal-regulated kinase (ERK), and NADPH oxidase (NOX)-derived reactive oxygen species (ROS).

Tetradecanoylphorbol Acetate 13-16 mitogen-activated protein kinase kinase 7 Homo sapiens 44-47 23353996-7 2013 Taken together, we suggest that silibinin suppresses TPA-induced cell migration and MMP-9 expression through the MEK/ERK-dependent pathway in thyroid and breast cancer cells. Tetradecanoylphorbol Acetate 53-56 mitogen-activated protein kinase kinase 7 Homo sapiens 125-128 22052014-8 2012 In addition, blockade of PKCdelta by rottlerin, a PKCdelta-specific inhibitor, and ERK1/2 by U0126, a MEK-ERK inhibitor, abrogated PMA-induced Egr-1 expression. Tetradecanoylphorbol Acetate 131-134 mitogen-activated protein kinase kinase 7 Homo sapiens 102-105 22052014-5 2012 We show that, in response to PMA, PKCdelta, a member of novel PKC isozymes, and MEK-ERK1/2 pathway of mitogen-activated protein kinases stimulate the NHE2 expression in C2BBe1 intestinal epithelial cells. Tetradecanoylphorbol Acetate 29-32 mitogen-activated protein kinase kinase 7 Homo sapiens 80-83 23175175-4 2013 The upregulation of these miRNAs was further verified by quantitative RT-PCR, and, markedly, a subset of the miRNAs was found to be induced via the MEK/ERK signaling pathway using TPA and specific pharmacological inhibitors. Tetradecanoylphorbol Acetate 204-207 mitogen-activated protein kinase kinase 7 Homo sapiens 172-175 23175175-6 2013 Therefore, we identified the unique miRNAs that respond to TPA treatment in leukemia cells and demonstrated the essential role of the MEK/ERK signaling pathway in the induction of these miRNA transcripts.

Tetradecanoylphorbol Acetate 207-210 mitogen-activated protein kinase kinase 7 Homo sapiens 83-86 21659537-6 2011 Previous work indicated that mTORC1 activation by the phorbol ester PMA (phorbol 12-myristate 13-acetate) depends upon PKCs and may involve MEK. Tetradecanoylphorbol Acetate 73-104 mitogen-activated protein kinase kinase 7 Homo sapiens 140-143 21077177-10 2011 Overall, our results suggest that the expression of EC-SOD is decreased by TPA through intracellular signaling consisting of PKC, NOX-derived ROS and MEK/ERK, but not of NF-kappaB signaling. Tetradecanoylphorbol Acetate 75-78 mitogen-activated protein kinase kinase 7 Homo sapiens 150-153 21297032-11 2011 These results suggest that the MEK/ERK1/2 pathway is necessary but not sufficient to regulate the PMA-dependent activation of Nox5. Tetradecanoylphorbol Acetate 98-101 mitogen-activated protein kinase kinase 7 Homo sapiens 31-34 18282472-4 2008 However, caspase-9/-3-mediated cytotoxicity can be induced in TPA-differentiated cells if they are pretreated with a protein kinase C (PKC) or a mitogen activated protein kinase (MEK) inhibitor. Tetradecanoylphorbol Acetate 62-65 mitogen-activated protein kinase kinase 7 Homo sapiens 145-177 20299489-9 2010 Taken together, the results show that PMA activates the MEK-ERK pathway and strongly induces miRNA-34a expression, which in turn inhibits cell proliferation by repressing the expression of MEK1.

Tetradecanoylphorbol Acetate 0-3 mitogen-activated protein kinase kinase 7 Homo sapiens 12-15 19181503-10 2009 Taken together, we suggest that the inhibition of TPA-induced MMP-9 and VEGF expression by silibinin is mediated by the suppression of the Raf/MEK/ERK pathway in MCF-7 breast cancer cells. Tetradecanoylphorbol Acetate 50-53 mitogen-activated protein kinase kinase 7 Homo sapiens 143-146 18519570-7 2008 The TPA-induced phosphorylation of MEK, extracellular signal-regulated kinase, and p90 ribosomal s6 kinase was suppressed by CPF or procyanidin B2.

Tetradecanoylphorbol Acetate 24-27 mitogen-activated protein kinase kinase 7 Homo sapiens 100-103 18053806-6 2008 MEK kinase assay using myelin basic protein (MBP) revealed that TPA-augmented MEK activity in HT-1080 cells and that the augmented MEK activity was diminished by nobiletin treatment. Tetradecanoylphorbol Acetate 64-67 mitogen-activated protein kinase kinase 7 Homo sapiens 0-3 18053806-6 2008 MEK kinase assay using myelin basic protein (MBP) revealed that TPA-augmented MEK activity in HT-1080 cells and that the augmented MEK activity was diminished by nobiletin treatment. Tetradecanoylphorbol Acetate 64-67 mitogen-activated protein kinase kinase 7 Homo sapiens 78-81 18053806-6 2008 MEK kinase assay using myelin basic protein (MBP) revealed that TPA-augmented MEK activity in HT-1080 cells and that the augmented MEK activity was diminished by nobiletin treatment. Tetradecanoylphorbol Acetate 64-67 mitogen-activated protein kinase kinase 7 Homo sapiens 78-81 17114644-6 2007 In addition, ascofuranone suppressed PMA-induced phosphorylation of Ras, Raf, MEK and extracellular signal-regulated kinase (ERK), upstream factors involved in AP-1activation, whereas the phosphorylation of p38 and JNK/mitogen-activated protein kinase was not affected by ascofuranone, suggesting that the primary target of ascofuranone for suppression of the AP-1 induction is present in upstream of ERK signaling pathway. Tetradecanoylphorbol Acetate 37-40 mitogen-activated protein kinase kinase 7 Homo sapiens 78-81 16169661-0 2006 Protein kinase C alpha trigger Ras and Raf-independent MEK/ERK activation for TPA-induced growth inhibition of human hepatoma cell HepG2. Tetradecanoylphorbol Acetate 78-81 mitogen-activated protein kinase kinase 7 Homo sapiens 55-58 17101779-4 2007 Here we show that stimulation by tetradecanoyl phorbol acetate (TPA) attenuates PPARgamma"s activity in a MEK-dependent manner, even when Ser84 is mutated to Ala.

Tetradecanoylphorbol Acetate 64-67 mitogen-activated protein kinase kinase 7 Homo sapiens 106-109 17394769-3 2007 Though no apparent elevation of ERK activity was observed during the apoptosis in NB4 cells caused by 20 microM sodium selenite treatment, PD98059 and U0126, specific chemical inhibitors of the MEK/ERK signaling pathway, were shown to strongly prevent the apoptosis process, while ERK activator TPA enhanced the process. Tetradecanoylphorbol Acetate 295-298 mitogen-activated protein kinase kinase 7 Homo sapiens 194-197 17131377-5 2007 ICAM-1 expression in response to TPA was inhibited by pretreatment with GF109203X [a specific inhibitor of protein kinase C (PKC)], or with PD98059 and U0126 (specific inhibitors of MEK), suggesting the importance of PKC, and Erk1/2 signaling cascades in this response. Tetradecanoylphorbol Acetate 33-36 mitogen-activated protein kinase kinase 7 Homo sapiens 182-185 16868480-10 2006 TPA induced extracellular signal-regulated kinase1/2 phosphorylation, whereas the MEK inhibitor, PD98059, blocked the TPA-induced p21 expression.

Tetradecanoylphorbol Acetate 13-16 mitogen-activated protein kinase kinase 7 Homo sapiens 59-62 16169661-9 2006 Consistently, Western blot of Phospho(ser-218/222)-MEK demonstrated that phosphorylation of MEK-1 was greatly induced by 50nM TPA, which can be prevented by the PKC inhibitor Bisindolylmaleimides II. Tetradecanoylphorbol Acetate 126-129 mitogen-activated protein kinase kinase 7 Homo sapiens 51-54 16169661-14 2006 Taken together, we conclude that PKCalpha may activate MEK, independently of Raf and Ras, to trigger sustained ERK (MAPK) signaling and cell cycle arrest of HepG2 induced by TPA.

Tetradecanoylphorbol Acetate 199-202 mitogen-activated protein kinase kinase 7 Homo sapiens 79-82 16571380-7 2006 In mechanistic terms, the transcriptional upregulation of SK-1 is dependent on PKC and the extracellular signal-regulated protein kinase (ERK) cascade since staurosporine and the MEK inhibitor U0126 abolish the TPA-induced SK-1 induction. Tetradecanoylphorbol Acetate 211-214 mitogen-activated protein kinase kinase 7 Homo sapiens 179-182 17329956-4 2006 Induction of cyclin D1 expression in TPA-treated HL60 cells was inhibited with protein kinase C (PKC) inhibitor bisindolylmaleimide I and mitogen activated protein kinase kinase (MEK) inhibitor PD98059.

Tetradecanoylphorbol Acetate 14-45 mitogen-activated protein kinase kinase 7 Homo sapiens 118-121 16351709-7 2005 Furthermore, the TPA-mediated post-transcriptional mechanism of p21WAF1-enhanced expression in RD cells is due to activation of the MEK/ERK pathway, as shown by transfections with constitutively active MEK1 or MEK2, which induces p21WAF1 expression, and with ERK1 and ERK2 siRNA, which prevents p21WAF1 expression. Tetradecanoylphorbol Acetate 17-20 mitogen-activated protein kinase kinase 7 Homo sapiens 132-135 15757899-4 2005 Pretreatment with protein kinase C (PKC) inhibitor blocked the TPA-induced increase in NAG-1 protein levels and NF-kappa B binding/transcriptional activity, whereas an inhibition of p38, JNK, MEK activity had no effect on TPA-induced NAG-1 levels and NF-kappa B transcriptional activity. Tetradecanoylphorbol Acetate 63-66 mitogen-activated protein kinase kinase 7 Homo sapiens 192-195 12592382-5 2003 Pretreatment of 20 microg/ml PD98059, an inhibitor of MEK which is the upstream kinase of ERK, prevents the TPA- and Saikosaponin a-triggered HepG2 growth inhibition by 50 and 30%, respectively, accompanied by a 50 - 85% decrease of the p15(INK4b)/p16(INK4a) RNAs and proteins induced by both drugs. Tetradecanoylphorbol Acetate 108-111 mitogen-activated protein kinase kinase 7 Homo sapiens 54-57 14981539-6 2004 In addition, the MEK/ERK inhibitors, PD98059 and UO126, suppressed PMA-stimulated TRAF1 promoter activity indicating a role for ERK in TRAF1 induction.

Tetradecanoylphorbol Acetate 0-3 mitogen-activated protein kinase kinase 7 Homo sapiens 150-153 15147830-3 2004 The MEK inhibitor U0126 (0.1 to 10 microM) enhanced the TPA-induced ICAM-1 expression but not the IFN-gamma-induced one. Tetradecanoylphorbol Acetate 56-59 mitogen-activated protein kinase kinase 7 Homo sapiens 4-7 15147830-5 2004 Furthermore, PD98059 (0.5 to 50 microM), another MEK inhibitor, enhanced the TPA-induced ICAM-1 expression as well.

Tetradecanoylphorbol Acetate 30-61 mitogen-activated protein kinase kinase 7 Homo sapiens 167-170 12244094-4 2002 Conversely, the TPA-stimulated MEK binding and kinase activity are diminished when this region is deleted or Ser(338) and Ser(339) are mutated to alanines. Tetradecanoylphorbol Acetate 16-19 mitogen-activated protein kinase kinase 7 Homo sapiens 31-34 12444974-7 2002 NAMI-A was also able to inhibit the phosphorylation of MEK, the upstream activator of ERK, and, similar to both the protein kinase C (PKC) inhibitor GF109203X and the MAPK/ERK (MEK) inhibitor PD98059, it completely counteracted PMA-induced ERK phosphorylation. Tetradecanoylphorbol Acetate 228-231 mitogen-activated protein kinase kinase 7 Homo sapiens 55-58 12472895-10 2002 More importantly, both neurite outgrowth and phosphorylation of ERK by TPA were blocked by PD 098059, a specific inhibitor of MEK (MAP kinase/ERK kinase-1), but not by SB203580, a specific inhibitor of p38 MAP kinase. Tetradecanoylphorbol Acetate 71-74 mitogen-activated protein kinase kinase 7 Homo sapiens 126-129 12472895-10 2002 More importantly, both neurite outgrowth and phosphorylation of ERK by TPA were blocked by PD 098059, a specific inhibitor of MEK (MAP kinase/ERK kinase-1), but not by SB203580, a specific inhibitor of p38 MAP kinase. Tetradecanoylphorbol Acetate 71-74 mitogen-activated protein kinase kinase 7 Homo sapiens 131-154 12137745-6 2002 On immunoblot analysis, PMA enhanced NEP/CD10 expression in a dose- and time-dependent manner, which was completely abolished by Bis I and a mitogen-activated protein kinase (MAPK) kinase (MEK) inhibitor, PD98059. Tetradecanoylphorbol Acetate 24-27 mitogen-activated protein kinase kinase 7 Homo sapiens 189-192 12181747-5 2002 The inhibitory effect of TPA was mostly abrogated by pretreatment of a specific MEK inhibitor PD98059, indicating that the effect depends upon MEK/ERK-mediated signals.

Tetradecanoylphorbol Acetate 152-155 mitogen-activated protein kinase kinase 7 Homo sapiens 225-228 12009309-7 2002 Additionally, inhibition of MEK activity, which activates MAPK, attenuated TPA-induced OPN expression. Tetradecanoylphorbol Acetate 75-78 mitogen-activated protein kinase kinase 7 Homo sapiens 28-31 12048182-5 2002 Phorbol 12-myristate 13-acetate, a differentiation-inducing stimulus, potently activates the Ras-Raf-MEK-ERK pathway but only weakly activates PI3K/Akt and does not trigger the cross-talk. Tetradecanoylphorbol Acetate 0-31 mitogen-activated protein kinase kinase 7 Homo sapiens 101-104 11940578-3 2002 To explore the importance of the c-Raf/MAPK kinase (MEK)/MAPK pathway, we stimulated adult feline cardiomyocytes with 12-O-tetradecanoylphorbol-13-acetate (TPA), insulin, or forskolin to activate PKC, phosphatidylinositol-3-OH kinase, or protein kinase A (PKA), respectively.

Tetradecanoylphorbol Acetate 13-16 mitogen-activated protein kinase kinase 7 Homo sapiens 50-53 11799119-5 2002 The TPA-stimulated phosphorylation of all these sites is sensitive to inhibitors of MEK and to the inhibitor of mTOR, rapamycin, indicating that inputs from both mTOR and MEK are required for the regulation of 4E-BP1 phosphorylation by TPA.

Tetradecanoylphorbol Acetate 0-3 mitogen-activated protein kinase kinase 7 Homo sapiens 183-211 11719466-10 2001 Taken together, this study shows that a PKC-epsilon-Raf-1-MEK-ERK-AP1 signaling cascade acts on a 12-O-tetradecanoylphorbol-13-acetate response element-like element to mediate hypoxia-induced GRP78 expression in human gastric cancer cells. Tetradecanoylphorbol Acetate 98-134 mitogen-activated protein kinase kinase 7 Homo sapiens 58-61 11583819-4 2001 Moreover, Bge cell treatment with inhibitors of protein kinase C (PKC), Ras and MAPK kinase (Mek) suppressed PMA-induced expression of activated MAPK, suggesting that PKC-, Ras- and Mek-like molecules may be acting upstream of MAPK.

Tetradecanoylphorbol Acetate 36-39 mitogen-activated protein kinase kinase 7 Homo sapiens 84-87 11310793-8 2001 Studies using inhibitors for protein kinases involved in cell signaling pathways suggested that stress-activated kinase p38 and mitogen-activated protein kinase kinase MEK are involved in TPA-independent regulation of TYRP2 expression in melanocytes. Tetradecanoylphorbol Acetate 188-191 mitogen-activated protein kinase kinase 7 Homo sapiens 168-171 10871841-12 2000 PD98059 inhibited this increase, suggesting that TPA upregulation of p21WAF/CIP1 occurs via the MEK pathway, and that annexin V overexpression blunts it. Tetradecanoylphorbol Acetate 49-52 mitogen-activated protein kinase kinase 7 Homo sapiens 96-99 11124968-4 2001 In addition, reduction in CD45 expression caused the duration of peak PMA-induced MEK and extracellular signal-regulated kinase (ERK) 1/2 activity to increase from 5 min to 30 min while leading to a 4-fold increase in PMA-dependent PKCdelta activation. Tetradecanoylphorbol Acetate 70-73 mitogen-activated protein kinase kinase 7 Homo sapiens 82-85 11124968-6 2001 Finally, inhibitors of MEK (PD98059) and PKCdelta (rottlerin) completely blocked PMA-induced monocytic cell differentiation.

Tetradecanoylphorbol Acetate 86-89 mitogen-activated protein kinase kinase 7 Homo sapiens 49-52 10523856-3 1999 Downstream of protein kinase C (PKC), the effects of TPA are often mediated by the Raf-1/MEK/ERK mitogen-activated protein kinase (MAPK) cascade, and Raf-1 has been implicated in MDR1 induction by serum and mitogens. Tetradecanoylphorbol Acetate 53-56 mitogen-activated protein kinase kinase 7 Homo sapiens 89-92 10871841-5 2000 Morphological changes induced by TPA were reduced by annexin V overexpression as well as by the pan-PKC inhibitor, bisindolylmaleimide I, and by the mitogen-activated protein kinase/extracellular signal-regulated kinase kinase (MEK) inhibitor, PD98059. Tetradecanoylphorbol Acetate 33-36 mitogen-activated protein kinase kinase 7 Homo sapiens 228-231 10733524-3 2000 We show that induction of the circadian oscillation of gene expression is triggered by TPA treatment of NIH-3T3 fibroblasts, which is inhibited by a MEK inhibitor, and that prolonged activation of the MAPK cascade is sufficient to trigger circadian gene expression.

Tetradecanoylphorbol Acetate 98-101 mitogen-activated protein kinase kinase 7 Homo sapiens 72-75 10737257-1 2000 The purpose of this study was to evaluate whether the mitogen-activated protein kinase/extracellular signal-regulated kinase (MEK) signaling pathway contributes to 12-O-tertadecanoyl phorbol 13-acetate (TPA)-mediated protection from taxol-induced apoptosis of human leukemia HL-60 cells. Tetradecanoylphorbol Acetate 203-206 mitogen-activated protein kinase kinase 7 Homo sapiens 54-124 10737257-1 2000 The purpose of this study was to evaluate whether the mitogen-activated protein kinase/extracellular signal-regulated kinase (MEK) signaling pathway contributes to 12-O-tertadecanoyl phorbol 13-acetate (TPA)-mediated protection from taxol-induced apoptosis of human leukemia HL-60 cells. Tetradecanoylphorbol Acetate 203-206 mitogen-activated protein kinase kinase 7 Homo sapiens 126-129 10737257-4 2000 Since TPA stimulates MEK signal transduction pathway in HL-60 cells, we postulated that MEK pathway may be playing a role in the ability of TPA to inhibit taxol-induced apoptosis.

Tetradecanoylphorbol Acetate 68-71 mitogen-activated protein kinase kinase 7 Homo sapiens 21-24 10523856-8 1999 TPA also activated the Raf1/MEK/ERK cascade and activated another MAPK member, p38, but not JNK. Tetradecanoylphorbol Acetate 0-3 mitogen-activated protein kinase kinase 7 Homo sapiens 28-31 10523856-10 1999 The MEK inhibitor PD 098059, as well as the PKC inhibitors, completely blocked TPA-mediated ERK activation. Tetradecanoylphorbol Acetate 79-82 mitogen-activated protein kinase kinase 7 Homo sapiens 4-7 10319997-3 1999 A direct relationship between sustained p42MAPK activation and differentiation is provided by the demonstration that blockade of MEK activation by PD098059 prevents TPA-induced morphological differentiation of wild type U937 cells. Tetradecanoylphorbol Acetate 165-168 mitogen-activated protein kinase kinase 7 Homo sapiens 129-132 10446156-8 1999 Inhibition of MEK blocked both bombesin- and phorbol 12-myristate 13-acetate-induced secretion. Tetradecanoylphorbol Acetate 45-76 mitogen-activated protein kinase kinase 7 Homo sapiens 14-17 10359012-4 1999 Treatment of cells with PD98059, a specific inhibitor of mitogen-activated protein kinase kinase (MEK), inhibited TPA-induced ERK2 activity. Tetradecanoylphorbol Acetate 114-117 mitogen-activated protein kinase kinase 7 Homo sapiens 98-101 10359012-6 1999 We conclude that activation of the MEK/ERK signaling pathway is necessary for TPA-induced mononuclear cell differentiation. Tetradecanoylphorbol Acetate 78-81 mitogen-activated protein kinase kinase 7 Homo sapiens 35-38 10319997-2 1999 This is shown to be due to the inability of TPA to maintain activation of MAP/extracellular signal-regulated kinase kinase (MEK) and cRaf1. Tetradecanoylphorbol Acetate 44-47 mitogen-activated protein kinase kinase 7 Homo sapiens 124-127 10102471-11 1999 PD 098059 and U0126, both highly specific MEK inhibitors, efficiently prevented PMA-induced PAI-1 synthesis (mRNA and protein levels) and cell adhesion whereas SB203580, a specific inhibitor of stress-activated MAPK p38, did not. Tetradecanoylphorbol Acetate 80-83 mitogen-activated protein kinase kinase 7 Homo sapiens 42-45 10102471-13 1999 In conclusion, we propose that the pathway PKCbeta-MEK-MAPK p42 is a potential linear route for PAI-1 synthesis leading to morphological changes and adherence linked to PMA-induced differentiation in HL-60 cells. Tetradecanoylphorbol Acetate 169-172 mitogen-activated protein kinase kinase 7 Homo sapiens 51-54 9797142-3 1998 Similarly, PD98059, a specific inhibitor of MEK, abolished p21(WAF1/CIP1) induction and PMA-induced growth arrest.

Tetradecanoylphorbol Acetate 36-39 mitogen-activated protein kinase kinase 7 Homo sapiens 121-124 9183012-5 1997 Similarly, the expression of MEK- and of [Asn17]Ras mutants decreased the 12-O-tetradecanoyl-phorbol 13-acetate (TPA)-mediated p21(waf1/cip1) induction. Tetradecanoylphorbol Acetate 74-111 mitogen-activated protein kinase kinase 7 Homo sapiens 29-32 10397459-5 1998 However, PMA-induced differentiation was blocked by pretreatment with PD98059, a specific inhibitor of MEK, in both parental and NF-kappaB-transfected cells.

Tetradecanoylphorbol Acetate 89-92 mitogen-activated protein kinase kinase 7 Homo sapiens 30-33 9553058-2 1998 We have identified a distal IL-2 enhancer regulated by the Raf-MEK-ERK signaling pathway, which can be induced by TPA/ionomycin treatment. Tetradecanoylphorbol Acetate 114-117 mitogen-activated protein kinase kinase 7 Homo sapiens 63-66 9553058-7 1998 Furthermore, the JNK/SAPK signaling pathway cooperates with the Raf-MEK-ERK cascade in TPA/ionomycin-induced DSE activity. Tetradecanoylphorbol Acetate 87-90 mitogen-activated protein kinase kinase 7 Homo sapiens 68-71 9392422-11 1997 Based on a close kinetic correlation between PKC alpha translocation and ERK activation, and the effects of specific inhibitors, these findings suggest that translocation/activation of PKC alpha, and subsequent activation of the Raf-1/MEK/ERK MAPK cascade, represent key events in the transcriptional induction of LDL receptor gene by TPA in HepG2 cells. Tetradecanoylphorbol Acetate 335-338 mitogen-activated protein kinase kinase 7 Homo sapiens 235-238 9804192-4 1998 Pretreatment of cells with MEK inhibitor, PD98059, inhibited TPA-induced phosphorylation of ERK1/2 and the cytoprotective ability of TPA.

Tetradecanoylphorbol Acetate 35-38 mitogen-activated protein kinase kinase 7 Homo sapiens 15-18 9473349-3 1998 These PMA-induced changes in K562 cells are preceded by a rapid rise in the activity of MEK (MAP kinase/extracellular regulated kinases) that leads to a sustained activation of ERK2 (extracellular regulated kinase; MAPK). Tetradecanoylphorbol Acetate 6-9 mitogen-activated protein kinase kinase 7 Homo sapiens 88-91 9473349-3 1998 These PMA-induced changes in K562 cells are preceded by a rapid rise in the activity of MEK (MAP kinase/extracellular regulated kinases) that leads to a sustained activation of ERK2 (extracellular regulated kinase; MAPK). Tetradecanoylphorbol Acetate 6-9 mitogen-activated protein kinase kinase 7 Homo sapiens 93-135 9183012-5 1997 Similarly, the expression of MEK- and of [Asn17]Ras mutants decreased the 12-O-tetradecanoyl-phorbol 13-acetate (TPA)-mediated p21(waf1/cip1) induction. Tetradecanoylphorbol Acetate 113-116 mitogen-activated protein kinase kinase 7 Homo sapiens 29-32 8798560-3 1996 Treatment of cells with TPA or epidermal growth factor resulted in the activation of MEK and ERK.

Tetradecanoylphorbol Acetate 16-19 mitogen-activated protein kinase kinase 7 Homo sapiens 69-72 8663100-7 1996 The MAPK and NHE activities induced by PMA were inhibited by staurosporine, a potent inhibitor for protein kinase C (PKC), and by MAPK kinase (MEK) inhibitor, PD98059, but were not affected by the tyrosine kinase inhibitor genistein. Tetradecanoylphorbol Acetate 39-42 mitogen-activated protein kinase kinase 7 Homo sapiens 143-146 7936644-4 1994 Using recombinant proteins and in vitro phosphorylation reactions we identified the components in the signal transduction pathway from TPA to MAPkinase and we show that the activation of MAPkinase by TPA requires the presence of protein kinase C, c-raf and the MAPkinase activator MEK.

Tetradecanoylphorbol Acetate 200-203 mitogen-activated protein kinase kinase 7 Homo sapiens 281-284 8352882-7 1993 When MEK and HEK cultures were treated with TPA for 3 h, less than 30% of the control level of PKC activity was detected, indicating that TPA-induced downregulation of PKC was similar in MEKs and HEKs. Tetradecanoylphorbol Acetate 44-47 mitogen-activated protein kinase kinase 7 Homo sapiens 5-8 8175693-1 1994 Treatment of adipocytes with insulin or phorbol 12-myristate 13-acetate (PMA) results in transient activation of mitogen-activated protein kinase kinase (MEK) (Tmax = 90 s) and mitogen-activated protein kinase (MAPK) (Tmax = 300 s).

Tetradecanoylphorbol Acetate 73-76 mitogen-activated protein kinase kinase 7 Homo sapiens 154-157 8125975-2 1994 Following anti-IgM antibody and phorbol 12-myristate 13-acetate (PMA) stimulation, we demonstrate the activation of Ras, Raf-1, and MAPK/ERK kinase (MEK), all of which are thought to participate in an important signaling cascade that leads to MAPK activation.

TPA treatment of cultured HEKs, however, did not induce ODC activity; in fact, less activity, compared with that of control cultures, was observed. Tetradecanoylphorbol Acetate 21-24 mitogen-activated protein kinase kinase 7 Homo sapiens 26-29 8352882-8 1993 After treatment with TPA, MEK cultures produced a large induction of both c-jun and c-fos mRNA by 60 min, as determined by northern blot analysis, and a large induction of ODC mRNA and enzyme activity by 6 h.
