Tetradecanoylphorbol Acetate 0-25 interleukin 6 receptor Homo sapiens 62-67 11884403-7 2002 Protein kinase C inhibitors blocked phorbol myristate acetate-induced and spontaneous shedding of IL-6R resulting in the absence of sIL-6R in the culture medium, which in turn also prevented the activation of gp130. Tetradecanoylphorbol Acetate 36-61 interleukin 6 receptor Homo sapiens 98-103 11485567-4 2001 Here we provide evidence that PMA-induced IL-6Ralpha shedding is controlled by a metalloproteinase and by protein kinase C (PKC) isoenzymes that do not require Ca(2+) for their activation. Tetradecanoylphorbol Acetate 30-33 interleukin 6 receptor Homo sapiens 42-52 11485567-8 2001 In addition, by using rottlerin, a specific inhibitor of PKC-delta, we demonstrate that PKC-delta is involved in the PMA-induced shedding of IL-6Ralpha. Tetradecanoylphorbol Acetate 117-120 interleukin 6 receptor Homo sapiens 141-151 11485567-9 2001 With the use of UO126, a specific inhibitor of the mitogen-activated protein kinase (MAPK) pathway, we show that the PMA-induced IL-6Ralpha shedding is mediated in part by the MAPK pathway. Tetradecanoylphorbol Acetate 117-120 interleukin 6 receptor Homo sapiens 129-139 11485567-11 2001 Taken together, these results suggest that the PMA-induced shedding of IL-6Ralpha is mediated by a PKC isoenzyme network. Tetradecanoylphorbol Acetate 47-50 interleukin 6 receptor Homo sapiens 71-81 8440709-8 1993 Whereas treatment of HepG2 cells with PMA led to an increase in the formation of gp80.gp130.IL-6 complexes determined by cross-linking, no corresponding increase in high affinity binding sites was found. Tetradecanoylphorbol Acetate 38-41 interleukin 6 receptor Homo sapiens 81-85 10613356-1 1999 It has been previously shown that phorbol 12-myristate 13-acetate (PMA), a potent differentiation inducer, induced the expression of both interleukin-6 (IL-6) and IL-6 receptor alpha component (IL-6Ralpha) in K562 leukemia cells. Tetradecanoylphorbol Acetate 34-65 interleukin 6 receptor Homo sapiens 194-204 7594530-8 1995 To determine whether TAPI would prevent shedding under more physiologic conditions, we demonstrated that TAPI was able to prevent unstimulated and PMA-induced release of the soluble forms of TNF-alpha, p60 TNFR, and IL-6R from the monocytic cell line, THP-1, and from human peripheral blood monocytes. Tetradecanoylphorbol Acetate 147-150 interleukin 6 receptor Homo sapiens 216-221 10613356-1 1999 It has been previously shown that phorbol 12-myristate 13-acetate (PMA), a potent differentiation inducer, induced the expression of both interleukin-6 (IL-6) and IL-6 receptor alpha component (IL-6Ralpha) in K562 leukemia cells. Tetradecanoylphorbol Acetate 67-70 interleukin 6 receptor Homo sapiens 194-204 10406952-6 1999 IL-6RDeltaIg was shed as effectively as wild-type IL-6R from transfected COS-7 cells upon 4beta-phorbol 12-myristate 13-acetate (PMA) treatment, whereas nonstimulated shedding of IL-6RDeltaIg was not observed. Tetradecanoylphorbol Acetate 90-127 interleukin 6 receptor Homo sapiens 0-5 10406952-6 1999 IL-6RDeltaIg was shed as effectively as wild-type IL-6R from transfected COS-7 cells upon 4beta-phorbol 12-myristate 13-acetate (PMA) treatment, whereas nonstimulated shedding of IL-6RDeltaIg was not observed. Tetradecanoylphorbol Acetate 129-132 interleukin 6 receptor Homo sapiens 0-5 9674743-6 1998 In addition, phorbol 12-myristate 13-acetate (PMA) stimulated a loss of IL-6R from the cell surface, with a corresponding increase in the concentration of sIL-6R in the supernatant. Tetradecanoylphorbol Acetate 13-44 interleukin 6 receptor Homo sapiens 72-77 9674743-6 1998 In addition, phorbol 12-myristate 13-acetate (PMA) stimulated a loss of IL-6R from the cell surface, with a corresponding increase in the concentration of sIL-6R in the supernatant. Tetradecanoylphorbol Acetate 46-49 interleukin 6 receptor Homo sapiens 72-77 1290964-3 1992 We found that GM-CSFR beta-subunit mRNA was expressed constitutively in CMK cells and was transiently down-regulated by TPA and IL-6, while the expression of IL-6R mRNA was increased by TPA in association with the differentiation of megakaryocytes. Tetradecanoylphorbol Acetate 186-189 interleukin 6 receptor Homo sapiens 158-163 8436181-3 1993 Shedding of the gp80 protein was strongly induced by 4 beta-phorbol-12-myristate-13-acetate, indicating that the process was regulated by protein kinase C (PKC). Tetradecanoylphorbol Acetate 53-91 interleukin 6 receptor Homo sapiens 16-20 1337986-3 1992 Our data show a definite downregulation of IL-6R and gp130 expression by TPA in U266 and BMNH at both mRNA and cell surface protein levels. Tetradecanoylphorbol Acetate 73-76 interleukin 6 receptor Homo sapiens 43-48 1337986-4 1992 In U937 TPA inhibits only the IL-6R expression, without affecting that of gp130.
