Sirolimus 136-145 ribosomal protein S6 kinase B1 Homo sapiens 43-50 10373483-5 1999 TNFalpha inhibited p70(s6k) activation by glucose-stimulated beta-cells of the islets of Langerhans in a dose- and time-dependent manner, with maximal inhibition observed at approximately 20-50 ng/ml, detected after 24 and 48 h of exposure. Glucose 42-49 ribosomal protein S6 kinase B1 Homo sapiens 19-26 10206976-7 1999 Leucine also stimulated phosphorylation of the ribosomal protein S6 kinase, p70(S6k), resulting in increased phosphorylation of S6. Leucine 0-7 ribosomal protein S6 kinase B1 Homo sapiens 80-83 10212283-1 1999 To understand the mechanisms of prostaglandin F2alpha (PGF2alpha)-induced protein synthesis in vascular smooth muscle cells (VSMC), we have studied its effect on two major signal transduction pathways: mitogen-activated protein kinases and phosphatidylinositol 3-kinase (PI3-kinase) and their downstream targets ribosomal protein S6 kinase (p70(S6k)) and eukaryotic initiation factor eIF4E and its regulator 4E-BP1. Dinoprost 32-53 ribosomal protein S6 kinase B1 Homo sapiens 341-348 10212283-1 1999 To understand the mechanisms of prostaglandin F2alpha (PGF2alpha)-induced protein synthesis in vascular smooth muscle cells (VSMC), we have studied its effect on two major signal transduction pathways: mitogen-activated protein kinases and phosphatidylinositol 3-kinase (PI3-kinase) and their downstream targets ribosomal protein S6 kinase (p70(S6k)) and eukaryotic initiation factor eIF4E and its regulator 4E-BP1. Dinoprost 55-64 ribosomal protein S6 kinase B1 Homo sapiens 341-348 10212283-2 1999 PGF2alpha induced the activities of extracellular signal-regulated kinase 2 (ERK2) and Jun N-terminal kinase 1 (JNK1) groups of mitogen-activated protein kinases, PI3-kinase, and p70(S6k) in a time-dependent manner in growth-arrested VSMC. Dinoprost 0-9 ribosomal protein S6 kinase B1 Homo sapiens 183-186 10212283-4 1999 Whereas inhibition of PI3-kinase by wortmannin completely blocked the p70(S6k) activation, it only partially decreased the ERK2 activity, and had no significant effect on global protein synthesis and bFGF-2 expression induced by PGF2alpha. Wortmannin 36-46 ribosomal protein S6 kinase B1 Homo sapiens 70-77 10212283-5 1999 Rapamycin, a potent inhibitor of p70(S6k), also failed to prevent PGF2alpha-induced global protein synthesis and bFGF-2 expression, although it partially decreased ERK2 activity. Sirolimus 0-9 ribosomal protein S6 kinase B1 Homo sapiens 37-40 10200280-7 1999 FRAP also is shown to phosphorylate PP2A in vitro, consistent with a model in which phosphorylation of PP2A by FRAP prevents the dephosphorylation of 4E-BP1 and p70(s6k), whereas amino acid deprivation or rapamycin treatment inhibits FRAP"s ability to restrain the phosphatase. Sirolimus 205-214 ribosomal protein S6 kinase B1 Homo sapiens 161-168 10085104-6 1999 Similarly, although p70(s6k) was activated during GH priming, pretreatment of cells with rapamycin, which prevented the activation of p70(s6k), had no effect on GH priming. Sirolimus 89-98 ribosomal protein S6 kinase B1 Homo sapiens 134-141 10200280-2 1999 Depriving cells of amino acids or treating them with the small molecule rapamycin inhibits FRAP and results in rapid dephosphorylation and inactivation of the translational regulators 4E-BP1(eukaryotic initiation factor 4E-binding protein 1) and p70(s6k) (the 70-kDa S6 kinase). Sirolimus 72-81 ribosomal protein S6 kinase B1 Homo sapiens 246-253 10200280-5 1999 A calyculin A-sensitive phosphatase is required for the rapamycin- or amino acid deprivation-induced dephosphorylation of p70(s6k), and treatment of Jurkat I cells with rapamycin increases the activity of the protein phosphatase 2A (PP2A) toward 4E-BP1. Sirolimus 56-65 ribosomal protein S6 kinase B1 Homo sapiens 122-129 10082559-3 1999 Data accumulated thus far support a model whereby p70S6K activation requires sequential phosphorylations at proline-directed residues in the putative autoinhibitory pseudosubstrate domain, as well as threonine 389. Proline 108-115 ribosomal protein S6 kinase B1 Homo sapiens 50-56 10082559-3 1999 Data accumulated thus far support a model whereby p70S6K activation requires sequential phosphorylations at proline-directed residues in the putative autoinhibitory pseudosubstrate domain, as well as threonine 389. Threonine 200-209 ribosomal protein S6 kinase B1 Homo sapiens 50-56 10082559-12 1999 This work provides evidence for a link between a phorbol ester-insensitive PKC isoform and p70S6K. Phorbol Esters 49-62 ribosomal protein S6 kinase B1 Homo sapiens 91-97 10226782-4 1999 In that study we found that PD098059, an inhibitor of MEK activation, inhibited the proliferative response, but dramatically enhanced IGF-stimulated differentiation which was associated with elevation of p70s6k activity. 2-(2-amino-3-methoxyphenyl)-4H-1-benzopyran-4-one 28-36 ribosomal protein S6 kinase B1 Homo sapiens 204-210 10029080-14 1999 To examine the rate at which the mTOR pathway recovered, the ability of IGF-I to stimulate p70S6K activity was followed in cells treated for 1 h with rapamycin and then allowed to recover in medium containing > or =100-fold excess of FK506 (to prevent rapamycin from rebinding to its cytosolic receptor FKBP-12). Sirolimus 150-159 ribosomal protein S6 kinase B1 Homo sapiens 91-97 9895282-8 1999 However, inhibition of p70S6 kinase (p70(s6k)) with rapamycin or of mitogen-activated protein kinase (MAPK) with PD098059 does not preclude insulin effects on GLUT4 gene expression or glucose uptake. Sirolimus 52-61 ribosomal protein S6 kinase B1 Homo sapiens 37-44 9914383-2 1998 In mammalian cells, rapamycin selectively inhibits phosphorylation and activation of p70 S6 kinase (p70(S6K)), a protein involved in the translation of a subset of mRNAs, without affecting other known kinases. Sirolimus 20-29 ribosomal protein S6 kinase B1 Homo sapiens 107-108 9873015-5 1999 A partial decrease in the fold activation of GS was, however, observed when p70(S6k) activation was blocked with rapamycin, suggesting a contribution of this pathway to the control of GS by either hormone. Sirolimus 113-122 ribosomal protein S6 kinase B1 Homo sapiens 80-83 10427963-3 1999 Bau is a splice form of Neurabin-I, one of two related F-actin-binding proteins that are proposed to link cadherin-based cell-cell adhesion sites with the growth regulatory kinase p70S6K. 5-benzylacyclouridine 0-3 ribosomal protein S6 kinase B1 Homo sapiens 180-186 10427963-8 1999 We suggest that Bau may link Bin1 to the Neurabin-I/p70S6K system in muscle and other cells, perhaps providing a mechanism to influence adhesion-dependent signals which affect cell fate. 5-benzylacyclouridine 16-19 ribosomal protein S6 kinase B1 Homo sapiens 52-58 9852118-7 1998 These findings support the interpretation that increasing cAMP attenuates the effects of insulin on PHAS-I, p70(S6K), and other downstream targets of the mTOR signaling pathway by inhibiting the phosphorylation and activation of mTOR. Cyclic AMP 58-62 ribosomal protein S6 kinase B1 Homo sapiens 112-115 9914383-6 1998 In quiescent mammalian cells (human lymphocytes and CHEF cells) induced with growth factor to re-enter the cell cycle, rapamycin was effective when cells were exposed at the time of p70(S6K) activation. Sirolimus 119-128 ribosomal protein S6 kinase B1 Homo sapiens 182-185 9804755-6 1998 Similarly to p70alpha, the catalytic activity of p70beta toward ribosomal protein S6 could be rapidly activated by serum, insulin, and phorbol ester in transiently transfected cells. Phorbol Esters 135-148 ribosomal protein S6 kinase B1 Homo sapiens 13-21 9774438-12 1998 We propose that amino acids, in particular branched-chain amino acids, may promote beta-cell proliferation either by stimulating phosphorylation of PHAS-I and p70(s6k) via the mammalian target of rapamycin pathway and/or by facilitating the proliferative effect mediated by growth factors such as insulin and IGF-I. Amino Acids, Branched-Chain 43-69 ribosomal protein S6 kinase B1 Homo sapiens 159-166 9751223-2 1998 Full activation of MAPK requires tyrosine and threonine phosphorylation whereas that of p70S6K requires serine phosphorylation. Serine 104-110 ribosomal protein S6 kinase B1 Homo sapiens 88-94 9774384-5 1998 PECAM-1/CD31-dependent recruitment of PI3K was suggested by the finding that the serine/threonine kinase p70 S6 kinase (S6K), a signaling protein downstream of PI3K, is activated in neutrophils upon PECAM-1/CD31 cross-linking, based on the appearance of serine phosphorylation in S6K immunoprecipitates. Serine 81-87 ribosomal protein S6 kinase B1 Homo sapiens 120-123 9774384-5 1998 PECAM-1/CD31-dependent recruitment of PI3K was suggested by the finding that the serine/threonine kinase p70 S6 kinase (S6K), a signaling protein downstream of PI3K, is activated in neutrophils upon PECAM-1/CD31 cross-linking, based on the appearance of serine phosphorylation in S6K immunoprecipitates. Serine 81-87 ribosomal protein S6 kinase B1 Homo sapiens 280-283 9751223-3 1998 In the present study, okadaic acid, which inhibits serine/threonine protein phosphatase activity, was used to explore the linkage of MAPK and p70S6K activation to down-stream effects of prolactin in Nb2 cells. Okadaic Acid 22-34 ribosomal protein S6 kinase B1 Homo sapiens 142-148 9751223-5 1998 Addition of okadaic acid alone a) stimulated and sustained p70S6K activity (5- to 8-fold) and MAPK (3.5- to 5-fold); and b) increased protein synthesis with the maximum effect being about equal to that of prolactin (2.1-fold with 1 nMokadaic acid versus 2.3-fold with 0.2 nMprolactin). Okadaic Acid 12-24 ribosomal protein S6 kinase B1 Homo sapiens 59-65 9675059-8 1998 The third step of purification consists of a single affinity chromatography column in which the ligand is a 20-residue peptide containing the structural motif required for recognition and binding by p70(S6k). Peptides 119-126 ribosomal protein S6 kinase B1 Homo sapiens 203-206 9768361-3 1998 Recent reports have also shown that the phosphoinositide-dependent protein kinase-1 (PDK-1), which binds with high affinity to the PI 3-kinase lipid product phosphatidylinositol-3,4,5-trisphosphate (Ptdins-3,4,5-P3), phosphorylates and potently activates two other PI 3-kinase targets, the protein kinases Akt/PKB and p70S6K. phosphatidylinositol 3,4,5-triphosphate 157-197 ribosomal protein S6 kinase B1 Homo sapiens 318-324 9768361-3 1998 Recent reports have also shown that the phosphoinositide-dependent protein kinase-1 (PDK-1), which binds with high affinity to the PI 3-kinase lipid product phosphatidylinositol-3,4,5-trisphosphate (Ptdins-3,4,5-P3), phosphorylates and potently activates two other PI 3-kinase targets, the protein kinases Akt/PKB and p70S6K. phosphatidylinositol 3,4,5-triphosphate 199-214 ribosomal protein S6 kinase B1 Homo sapiens 318-324 9733756-2 1998 Biochemical and confocal microscopy analyses at the level of the cardiocyte revealed that p70(S6K) is present predominantly in the cytosol, substantially activated in 1-h RVPO (>12 fold), and phosphorylated in the pseudosubstrate domain at the Ser-411, Thr-421, and Ser-424 sites. Serine 247-250 ribosomal protein S6 kinase B1 Homo sapiens 90-97 9733756-2 1998 Biochemical and confocal microscopy analyses at the level of the cardiocyte revealed that p70(S6K) is present predominantly in the cytosol, substantially activated in 1-h RVPO (>12 fold), and phosphorylated in the pseudosubstrate domain at the Ser-411, Thr-421, and Ser-424 sites.

Serine 269-272 ribosomal protein S6 kinase B1 Homo sapiens 90-97 9733756-3 1998 p85(S6K), which was localized exclusively in the nucleus, showed activation subsequent to p70(S6K), with a sustained increase in phosphorylation for up to 48 h of RVPO at equivalent sites of p70(S6K), Thr-421 and Ser-424, but not at Ser-411. rvpo 163-167 ribosomal protein S6 kinase B1 Homo sapiens 0-7 9733756-3 1998 p85(S6K), which was localized exclusively in the nucleus, showed activation subsequent to p70(S6K), with a sustained increase in phosphorylation for up to 48 h of RVPO at equivalent sites of p70(S6K), Thr-421 and Ser-424, but not at Ser-411. rvpo 163-167 ribosomal protein S6 kinase B1 Homo sapiens 4-7 9733756-3 1998 p85(S6K), which was localized exclusively in the nucleus, showed activation subsequent to p70(S6K), with a sustained increase in phosphorylation for up to 48 h of RVPO at equivalent sites of p70(S6K), Thr-421 and Ser-424, but not at Ser-411.

Serine 233-236 ribosomal protein S6 kinase B1 Homo sapiens 4-7 9733756-5 1998 Further studies to determine potential upstream elements of S6K activation revealed: (i) similar time course of activation for protein kinase C isoforms (alpha, gamma, and epsilon) and c-Raf, (ii) absence of accompanying phosphatidylinositol 3-kinase activation, (iii) activation of c-Src subsequent to p70(S6K), and (iv) similar changes in adult cardiocytes after treatment with 12-O-tetradecanoylphorbol-13-acetate. Tetradecanoylphorbol Acetate 380-416 ribosomal protein S6 kinase B1 Homo sapiens 60-63 9858932-0 1998 Evidence that phosphatidylinositol 3-kinase and p70S6K protein are involved in differentiation of HL-60 cells induced by calcitriol. Calcitriol 121-131 ribosomal protein S6 kinase B1 Homo sapiens 48-54 9465032-4 1998 RAFT1 phosphorylates p70(S6k) on Thr-389, a residue whose phosphorylation is rapamycin-sensitive in vivo and necessary for S6 kinase activity. Threonine 33-36 ribosomal protein S6 kinase B1 Homo sapiens 25-28 9578588-3 1998 We have shown earlier that different vanadium salts stimulate the MAP kinase pathway and ribosomal-S-6-kinase (p70s6k) in chinese hamster ovary cells overexpressing human insulin receptor (CHO-HIR cells) [Pandey, S. K., Chiasson, J.-L., and Srivastava, A. K. (1995) Mol. vanadium salts 37-51 ribosomal protein S6 kinase B1 Homo sapiens 111-117 9578588-8 1998 Treatment of CHO-HIR cells with VS resulted in increased glycogen synthesis and PI3-k activity which were blocked by pretreatment of the cells with wortmannin and LY294002, two specific inhibitors of PI3-k. On the other hand, PD98059 and rapamycin, specific inhibitors of the MAP kinase pathway and p70s6k, respectively, were unable to inhibit VS-stimulated glycogen synthesis. Wortmannin 148-158 ribosomal protein S6 kinase B1 Homo sapiens 299-305 9578588-8 1998 Treatment of CHO-HIR cells with VS resulted in increased glycogen synthesis and PI3-k activity which were blocked by pretreatment of the cells with wortmannin and LY294002, two specific inhibitors of PI3-k. On the other hand, PD98059 and rapamycin, specific inhibitors of the MAP kinase pathway and p70s6k, respectively, were unable to inhibit VS-stimulated glycogen synthesis. 2-(4-morpholinyl)-8-phenyl-4H-1-benzopyran-4-one 163-171 ribosomal protein S6 kinase B1 Homo sapiens 299-305 9528776-5 1998 Treatment of mammalian cells with rapamycin abolishes in vivo S6 phosphorylation by p70s6k; however, ectopic expression of AtS6k2 rescues the rapamycin block. Sirolimus 34-43 ribosomal protein S6 kinase B1 Homo sapiens 84-90 9614117-1 1998 The carboxyl terminus of p70 S6 kinase (p70(s6k)) has a set of Ser and Thr residues (Ser411, Ser418, Ser424, and Thr421) phosphorylated in vivo by an unidentified kinase(s).

Threonine 71-74 ribosomal protein S6 kinase B1 Homo sapiens 40-48 9531494-4 1998 CPPD crystals induced a robust, transient activation (peak activity at 2 min) of p70(S6K) that was fully inhibited by pretreatment with rapamycin. Sirolimus 136-145 ribosomal protein S6 kinase B1 Homo sapiens 85-88 9468542-8 1998 Furthermore, although PI3K in anti-phosphotyrosine immunoprecipitates is only very weakly activated by ionomycin, the calcium-induced stimulation of p70(S6k) is completely inhibited by the specific PI3K inhibitor wortmannin. Calcium 118-125 ribosomal protein S6 kinase B1 Homo sapiens 153-156 9468542-8 1998 Furthermore, although PI3K in anti-phosphotyrosine immunoprecipitates is only very weakly activated by ionomycin, the calcium-induced stimulation of p70(S6k) is completely inhibited by the specific PI3K inhibitor wortmannin. Wortmannin 213-223 ribosomal protein S6 kinase B1 Homo sapiens 153-156 9468542-11 1998 p70(S6k) requires a separate calcium-dependent and wortmannin-sensitive process that is likely to be independent of type IA PI3K family members. Calcium 29-36 ribosomal protein S6 kinase B1 Homo sapiens 4-7 9468542-11 1998 p70(S6k) requires a separate calcium-dependent and wortmannin-sensitive process that is likely to be independent of type IA PI3K family members. Wortmannin 51-61 ribosomal protein S6 kinase B1 Homo sapiens 4-7 9492293-3 1998 In mammals, activation of p70 ribosomal S6 kinase (p70S6k) has been implicated in translational control, in particular the selective up-regulation of translation of mRNAs with polypyrimidine tracts at their 5" start sites. polypyrimidine 176-190 ribosomal protein S6 kinase B1 Homo sapiens 51-57 9458731-3 1998 The stimulation of protein synthesis was accompanied by increased phosphorylation of p70S6k, an effect that was blocked by rapamycin and wortmannin but not PD-98059. Sirolimus 123-132 ribosomal protein S6 kinase B1 Homo sapiens 85-91 9458731-3 1998 The stimulation of protein synthesis was accompanied by increased phosphorylation of p70S6k, an effect that was blocked by rapamycin and wortmannin but not PD-98059. Wortmannin 137-147 ribosomal protein S6 kinase B1 Homo sapiens 85-91 9427627-4 1998 RESULTS: When equipped with an amino-terminal plasma membrane localization sequence and expressed in HEK293 cells, these chimeric receptors could signal to downstream targets as indicated by the FK1012-dependent activation of p70 S6 kinase (p70(S6k)) and mitogen-activated protein (MAP) kinase. FK 1012 195-201 ribosomal protein S6 kinase B1 Homo sapiens 241-248 9388274-7 1997 The role of PI 3-kinase in regulating heat shock activation of MAPK and p70 S6K was investigated using wortmannin, a specific pharmacological inhibitor of PI 3-kinase. Wortmannin 103-113 ribosomal protein S6 kinase B1 Homo sapiens 72-79 9468542-0 1998 Differential regulation by calcium reveals distinct signaling requirements for the activation of Akt and p70S6k. Calcium 27-34 ribosomal protein S6 kinase B1 Homo sapiens 105-111 9468542-6 1998 Depletion of intracellular calcium stores by EGTA pretreatment has no effect on growth factor-induced Akt activation but completely abolishes p70(S6k) stimulation. Calcium 27-34 ribosomal protein S6 kinase B1 Homo sapiens 146-149 9468542-6 1998 Depletion of intracellular calcium stores by EGTA pretreatment has no effect on growth factor-induced Akt activation but completely abolishes p70(S6k) stimulation. Egtazic Acid 45-49 ribosomal protein S6 kinase B1 Homo sapiens 146-149 9468542-7 1998 Increase of intracellular calcium induced by ionomycin or thapsigargin results in a full activation of p70(S6k), whereas little or no activation of Akt is observed. Calcium 26-33 ribosomal protein S6 kinase B1 Homo sapiens 107-110 9468542-7 1998 Increase of intracellular calcium induced by ionomycin or thapsigargin results in a full activation of p70(S6k), whereas little or no activation of Akt is observed. Ionomycin 45-54 ribosomal protein S6 kinase B1 Homo sapiens 107-110 9468542-7 1998 Increase of intracellular calcium induced by ionomycin or thapsigargin results in a full activation of p70(S6k), whereas little or no activation of Akt is observed. Thapsigargin 58-70 ribosomal protein S6 kinase B1 Homo sapiens 107-110 9388274-8 1997 The results demonstrated that wortmannin inhibited heat shock activation of p70 S6K but only partially inhibited heat activation of MAPK. Wortmannin 30-40 ribosomal protein S6 kinase B1 Homo sapiens 76-83 9299479-4 1997 These effects were completely reversed by a commonly used PI-3-kinase inhibitor, wortmannin, suggesting that p70S6K may be a downstream target of PI-3-kinase in a signaling cascade induced by gastrin. Wortmannin 81-91 ribosomal protein S6 kinase B1 Homo sapiens 109-115 21528277-0 1997 Rapamycin inhibits substance P-induced protein synthesis and phosphorylation of PHAS-I (4E-BP1) and p70 S6 kinase (p70(S6K)) in human astrocytoma cells. Sirolimus 0-9 ribosomal protein S6 kinase B1 Homo sapiens 100-103 21528277-6 1997 Further, we demonstrate that SP is potent in stimulating PHAS-I protein (also known as 4E-BP1) phosphorylation and p70 S6 kinase (p70(S6K)) phosphorylation and enzymatic activity, and that this stimulation is inhibited by subnanomolar concentrations of rapamycin. TFF2 protein, human 29-31 ribosomal protein S6 kinase B1 Homo sapiens 115-118 9266970-5 1997 Moreover, Dex-induced apoptosis is associated with a significant decrease in the activities of mitogen activated protein kinase (MAPK) and p70S6K, whereas IR-treatment does not alter the activity of these kinases. Dexamethasone 10-13 ribosomal protein S6 kinase B1 Homo sapiens 139-145 9248697-7 1997 Incubating 3T3-L1 adipocytes with rapamycin and wortmannin inhibited insulin-stimulated phosphorylation of PHAS-I at concentrations similar to those that inhibited activation of p70S6K. Sirolimus 34-43 ribosomal protein S6 kinase B1 Homo sapiens 178-184 9245714-6 1997 We also demonstrated that gastrin precursors activate the serine/threonine kinase, p70 kDa S6 kinase (p70S6K), through a wortmannin sensitive pathway. Wortmannin 121-131 ribosomal protein S6 kinase B1 Homo sapiens 83-100 9245714-6 1997 We also demonstrated that gastrin precursors activate the serine/threonine kinase, p70 kDa S6 kinase (p70S6K), through a wortmannin sensitive pathway. Wortmannin 121-131 ribosomal protein S6 kinase B1 Homo sapiens 102-108 9242178-3 1997 Our purpose was to determine whether p70S6K plays a role in cardiomyocyte hypertrophy induced by the alpha 1-adrenergic receptor (alpha 1-AR) agonist phenylephrine (PE). Phenylephrine 150-163 ribosomal protein S6 kinase B1 Homo sapiens 37-43 9242178-3 1997 Our purpose was to determine whether p70S6K plays a role in cardiomyocyte hypertrophy induced by the alpha 1-adrenergic receptor (alpha 1-AR) agonist phenylephrine (PE).

Sirolimus 13-22 ribosomal protein S6 kinase B1 Homo sapiens 79-85 9049301-5 1997 However, inhibition of PI3K and p70S6k by wortmannin and rapamycin, respectively, failed to antagonize AChR alpha-subunit gene expression stimulated by HRG, despite the fact that the activities of the kinases were inhibited. Wortmannin 42-52 ribosomal protein S6 kinase B1 Homo sapiens 32-38 9109413-6 1997 However, treatment of cells with a specific p70S6k pathway inhibitor, rapamycin, markedly attenuated FBS-stimulated PHAS-I phosphorylation. Sirolimus 70-79 ribosomal protein S6 kinase B1 Homo sapiens 44-50 9045696-6 1997 In sharp contrast, LY294002, an inhibitor of phosphatidylinositol 3-kinase, and rapamycin, an inhibitor of the activation of p70 S6 kinase (p70(S6k)), completely abolished IGF stimulation of L6A1 differentiation. Sirolimus 80-89 ribosomal protein S6 kinase B1 Homo sapiens 140-147 9175775-3 1997 Following insulin treatment, there was a retardation in mobility nuclear p70S6K in SDS-PAGE indicative of a change in phosphorylation of the enzyme, but no change in the amount of enzyme.

Sirolimus 0-9 ribosomal protein S6 kinase B1 Homo sapiens 155-161 8633019-2 1996 However, the immunosuppressant rapamycin blocks serum-induced 4E-BP1 phosphorylation and, in parallel, p70s6k activation, with no apparent effect on p42mapk activation. Sirolimus 31-40 ribosomal protein S6 kinase B1 Homo sapiens 103-109 8633019-5 1996 Anisomycin, which, like insulin, does not activate p42mapk, promotes a small parallel increase in 4E-BP1 phosphorylation and p70s6k activation.

Sirolimus 125-134 ribosomal protein S6 kinase B1 Homo sapiens 49-55 8633019-7 1996 These three inhibitors have no effect on p42mapk activation induced by phorbol 12-tetradecanoate 13-acetate, though wortmannin partially suppresses both the p70s6k response and the 4E-BP1 response. Wortmannin 116-126 ribosomal protein S6 kinase B1 Homo sapiens 157-163 8615823-4 1996 Pretreatment of cells with wortmannin, a specific inhibitor of PI 3-kinase, prevented the activation of p70s6k and partially inhibited the activation of p42 and p44 MAP kinases by GH.

The activation of p70(S6K) by calcium stimuli or Ang II was independent of calmodulin but correlated well with the activation of the recently identified, nonreceptor calcium-dependent tyrosine kinase (CADTK)/PYK-2. Calcium 180-187 ribosomal protein S6 kinase B1 Homo sapiens 168-171 8999881-9 1997 Both calcium- and Ang II-dependent activation of p70(S6K) were attenuated by the tyrosine kinase inhibitor genistein, and activation of p70(S6K) was higher in GN4 than WB cells, correlating with the increased expression and activation of CADTK/PYK-2 in GN4 cells. Calcium 5-12 ribosomal protein S6 kinase B1 Homo sapiens 49-52 8999881-9 1997 Both calcium- and Ang II-dependent activation of p70(S6K) were attenuated by the tyrosine kinase inhibitor genistein, and activation of p70(S6K) was higher in GN4 than WB cells, correlating with the increased expression and activation of CADTK/PYK-2 in GN4 cells. Calcium 5-12 ribosomal protein S6 kinase B1 Homo sapiens 53-56 8999881-9 1997 Both calcium- and Ang II-dependent activation of p70(S6K) were attenuated by the tyrosine kinase inhibitor genistein, and activation of p70(S6K) was higher in GN4 than WB cells, correlating with the increased expression and activation of CADTK/PYK-2 in GN4 cells.

Sirolimus 0-9 ribosomal protein S6 kinase B1 Homo sapiens 310-316 8603539-10 1996 Our data demonstrate that growth factor-mediated P70S6k activation is closely related to the growth of synovial fibroblast, and suggest the efficacy of rapamycin for controlling synovial hyperplasia in RA. Sirolimus 152-161 ribosomal protein S6 kinase B1 Homo sapiens 49-55 7592897-0 1995 The phosphodiesterase inhibitor SQ 20006 selectively blocks mitogen activation of p70S6k and transition to S phase of the cell division cycle without affecting the steady state phosphorylation of eIF-4E.

This response was completely abolished when the cells were incubated in the presence of the AT1-selective receptor antagonist losartan. Losartan 265-273 ribosomal protein S6 kinase B1 Homo sapiens 59-65 7566093-5 1995 Translational activation is prevented by rapamycin and mimicked by anisomycin, which suggests that translation of the 6.0-kb mRNA is regulated by the p70S6k/85S6k kinase signalling pathway.

Tris acetate 15-27 ribosomal protein S6 kinase B1 Homo sapiens 243-246 20203102-0 2010 Chronic inhibition of the mTORC1/S6K1 pathway increases insulin-induced PI3K activity but inhibits Akt2 and glucose transport stimulation in 3T3-L1 adipocytes. Glucose 108-115 ribosomal protein S6 kinase B1 Homo sapiens 33-37 20203102-3 2010 Acute inhibition of mTORC1/S6K1 by rapamycin increases insulin signaling and glucose uptake in myocytes and adipocytes, but whether these effects can be maintained under chronic inhibition of mTORC1 or S6K1 remains unclear. Sirolimus 35-44 ribosomal protein S6 kinase B1 Homo sapiens 27-31 20203102-3 2010 Acute inhibition of mTORC1/S6K1 by rapamycin increases insulin signaling and glucose uptake in myocytes and adipocytes, but whether these effects can be maintained under chronic inhibition of mTORC1 or S6K1 remains unclear.

Reactive Oxygen Species 28-31 ribosomal protein S6 kinase B1 Homo sapiens 58-61 10551813-4 1999 Further characterization of ROS-induced activation of p70(S6k) using specific inhibitors for p70(S6k) signaling pathway, rapamycin, and wortmannin revealed that ROS acted upstream of the rapamycin-sensitive component FRAP/RAFT and wortmannin-sensitive component phosphatidylinositol 3-kinase, because both inhibitors caused the inhibition of ROS-induced p70(S6k) activity. Reactive Oxygen Species 28-31 ribosomal protein S6 kinase B1 Homo sapiens 54-61 10551813-4 1999 Further characterization of ROS-induced activation of p70(S6k) using specific inhibitors for p70(S6k) signaling pathway, rapamycin, and wortmannin revealed that ROS acted upstream of the rapamycin-sensitive component FRAP/RAFT and wortmannin-sensitive component phosphatidylinositol 3-kinase, because both inhibitors caused the inhibition of ROS-induced p70(S6k) activity. Reactive Oxygen Species 28-31 ribosomal protein S6 kinase B1 Homo sapiens 97-100 10551813-4 1999 Further characterization of ROS-induced activation of p70(S6k) using specific inhibitors for p70(S6k) signaling pathway, rapamycin, and wortmannin revealed that ROS acted upstream of the rapamycin-sensitive component FRAP/RAFT and wortmannin-sensitive component phosphatidylinositol 3-kinase, because both inhibitors caused the inhibition of ROS-induced p70(S6k) activity. Sirolimus 121-130 ribosomal protein S6 kinase B1 Homo sapiens 58-61 10551813-4 1999 Further characterization of ROS-induced activation of p70(S6k) using specific inhibitors for p70(S6k) signaling pathway, rapamycin, and wortmannin revealed that ROS acted upstream of the rapamycin-sensitive component FRAP/RAFT and wortmannin-sensitive component phosphatidylinositol 3-kinase, because both inhibitors caused the inhibition of ROS-induced p70(S6k) activity. Sirolimus 121-130 ribosomal protein S6 kinase B1 Homo sapiens 54-61 10490848-4 1999 Conceptual translation of the SRK cDNA revealed that the catalytic domain of SRK was highly homologous to that of p70S6K, and that the treatment of wortmannin or rapamycin strongly inhibited the phosphorylation and the activation of SRK, as in p70S6K.
