Tetradecanoylphorbol Acetate 153-156 epidermal growth factor Homo sapiens 0-3 11272120-7 1980 Taken together, our results suggest that TPA inhibition of EGF-receptor binding results from TPA-induced changes in the membrane microenvironment of EGF receptors. Tetradecanoylphorbol Acetate 41-44 epidermal growth factor Homo sapiens 59-62 6259217-5 1981 Like EGF, the potent phorbol ester 12-O-tetradecanoyl-13-phorbol acetate (TPA) stimulates protein synthesis as indicated by a twofold increase in [(3)H]leucine incorporation into protein after 24 h in TPA. Tetradecanoylphorbol Acetate 74-77 epidermal growth factor Homo sapiens 5-8 6259217-9 1981 Furthermore, TPA inhibits cell division in media with or without serum, and prevents growth stimulation by EGF. Tetradecanoylphorbol Acetate 13-16 epidermal growth factor Homo sapiens 107-110 6265908-3 1981 12-O-Tetradecanoylphorbol 13-acetate also produced an increase in enzyme activity in these cells and exhibited an additive effect with EGF. Tetradecanoylphorbol Acetate 0-36 epidermal growth factor Homo sapiens 135-138 11272120-1 1980 This study analyzes the mechanism by which the tumor promoter 12-0-tetradecanoyl-phorbol 13-acetate (TPA) inhibits binding of epidermal growth factor (EGF) to its membrane receptors in HeLa cells. Tetradecanoylphorbol Acetate 101-104 epidermal growth factor Homo sapiens 126-149 11272120-1 1980 This study analyzes the mechanism by which the tumor promoter 12-0-tetradecanoyl-phorbol 13-acetate (TPA) inhibits binding of epidermal growth factor (EGF) to its membrane receptors in HeLa cells. Tetradecanoylphorbol Acetate 101-104 epidermal growth factor Homo sapiens 151-154 11272120-2 1980 Kinetic studies indicate that inhibition of EGF binding occurs within a few minutes after exposure of cells to TPA; delayed addition of TPA causes a reduction in previously bound EGF. Tetradecanoylphorbol Acetate 111-114 epidermal growth factor Homo sapiens 44-47 11272120-2 1980 Kinetic studies indicate that inhibition of EGF binding occurs within a few minutes after exposure of cells to TPA; delayed addition of TPA causes a reduction in previously bound EGF. Tetradecanoylphorbol Acetate 136-139 epidermal growth factor Homo sapiens 179-182 11272120-3 1980 With prolonged exposure to TPA, the cells become refractory to TPA inhibition of EGF binding. Tetradecanoylphorbol Acetate 27-30 epidermal growth factor Homo sapiens 81-84 11272120-7 1980 Taken together, our results suggest that TPA inhibition of EGF-receptor binding results from TPA-induced changes in the membrane microenvironment of EGF receptors. Tetradecanoylphorbol Acetate 41-44 epidermal growth factor Homo sapiens 149-152 11272120-3 1980 With prolonged exposure to TPA, the cells become refractory to TPA inhibition of EGF binding. Tetradecanoylphorbol Acetate 63-66 epidermal growth factor Homo sapiens 81-84 11272120-4 1980 Evidence was obtained that TPA acts by causing the dissociation of EGF-receptor complexes present on the cell surface and not by increasing the proteolytic degradation or internalization of EGF. Tetradecanoylphorbol Acetate 27-30 epidermal growth factor Homo sapiens 67-70 11272120-5 1980 Evidence that the TPA inhibition of EGF-receptor binding is not a direct consequence of TPA binding to the "active site" of EGF receptors was obtained by the differential effects of pH, temperature or exposure time and that TPA does not inhibit EGF binding when added to isolated plasma membrane fragments. Tetradecanoylphorbol Acetate 18-21 epidermal growth factor Homo sapiens 36-39 11272120-7 1980 Taken together, our results suggest that TPA inhibition of EGF-receptor binding results from TPA-induced changes in the membrane microenvironment of EGF receptors. Tetradecanoylphorbol Acetate 93-96 epidermal growth factor Homo sapiens 59-62 11272120-6 1980 Studies with a variety of inhibitors suggest that the TPA inhibition of EGF-receptor binding does not require macromolecular synthesis, energy metabolism, or cytoskeletal changes. Tetradecanoylphorbol Acetate 54-57 epidermal growth factor Homo sapiens 72-75 11272120-7 1980 Taken together, our results suggest that TPA inhibition of EGF-receptor binding results from TPA-induced changes in the membrane microenvironment of EGF receptors. Tetradecanoylphorbol Acetate 93-96 epidermal growth factor Homo sapiens 149-152 315558-1 1979 In previous studies we demonstrated that the tumor-promoting agent 12-O-tetradecanoyl phorbol 13-acetate (TPA) and related macrocyclic diterpenes are potent inhibitors of the binding of epidermal growth factor (EGF) to its cell surface receptors in HeLa cells.

Tetradecanoylphorbol Acetate 24-27 epidermal growth factor Homo sapiens 60-63 315558-6 1979 The TPA effect on EGF receptors is mediated by a highly temperature-dependent process because TPA inhibition of EGF binding, and TPA-induced release of prebound EGF, are much greater at 37 degrees C or 22 degrees C than at 4 degrees C.

Tetradecanoylphorbol Acetate 123-126 epidermal growth factor Homo sapiens 0-3 7534073-5 1995 However, when protein kinase C (PKC) was either inhibited by the PKC inhibitor GF 109203X or depleted by a prolonged TPA treatment, the stimulation of MBP phosphorylation by EGF was strongly inhibited. Tetradecanoylphorbol Acetate 117-120 epidermal growth factor Homo sapiens 174-177 7860643-11 1995 The role of protein kinase C (PKC) in the EGF-stimulated ERK signaling pathway was further examined by inhibition of PKC with the staurosporine analog, CGP41251, and by down-regulation of PKC via chronic treatment with PMA. Tetradecanoylphorbol Acetate 219-222 epidermal growth factor Homo sapiens 42-45 7835292-11 1995 EGF, on the other hand, only enhanced cell proliferation at a late stage (coincident with the TPA-mitogenic effect).

Tetradecanoylphorbol Acetate 204-207 epidermal growth factor Homo sapiens 84-87 8081876-3 1993 EGF-induced phosphorylation and communication inhibition were retained in cells pretreated with phorbol 12-myristate 13-acetate (PMA) to deplete protein kinase C. These results show that the EGF inhibition of communication is tightly linked to protein kinase C-independent phosphorylation of Cx43. Tetradecanoylphorbol Acetate 96-127 epidermal growth factor Homo sapiens 0-3 8045498-5 1994 Interleukin-1 beta and phorbol myristate acetate were also shown to induce in a dose-dependent fashion a threefold to fivefold increase of interleukin-6 production as measured by enzyme-linked immunosorbent assay in human primary biliary duct epithelium cultures, when compared with hepatocyte growth factor, epidermal growth factor, insulin-like growth factor, phytohemagglutinin, tumor necrosis factor-alpha or platelet-derived growth factor. Tetradecanoylphorbol Acetate 23-48 epidermal growth factor Homo sapiens 309-332 9397949-6 1994 In addition to estrogen, epidermal growth factor (EGF) and tumor promoter 12-O-tetradecanoylphorbol 13-acetate (TPA) can also induce c-myc expression with no effect on c-fos or lactoferrin expression. Tetradecanoylphorbol Acetate 112-115 epidermal growth factor Homo sapiens 25-48 8175715-5 1994 The sequence at position -52 to -40 (mLF-CRE) of the gene conferred transcriptional activation in the presence of forskolin, cyclic AMP, and 12-O-tetradecanoylphorbol-13-acetate in transiently transfected human endometrium carcinoma RL95-2 cells, whereas the region at -80 to -60 responded to EGF/TGF-alpha stimulation. Tetradecanoylphorbol Acetate 141-177 epidermal growth factor Homo sapiens 293-296 8224278-8 1993 The stimulation by EGF was attenuated by the treatment with genistein, 12-O-tetradecanoylphorbol-13-acetate, or thapsigargin. Tetradecanoylphorbol Acetate 71-107 epidermal growth factor Homo sapiens 19-22 7932377-9 1994 12-O-Tetradecanoylphorbol-13-acetate decreased the affinity of the receptor for EGF changing the dissociation constant from 1.8 to 3.9 nmol l-1. Tetradecanoylphorbol Acetate 0-36 epidermal growth factor Homo sapiens 80-83 8188084-2 1994 EGF (10 ng/ml) and the tumor promoter, protein kinase C agonist, phorbol 12-myristate 13-acetate (PMA) were potent stimulators (P < 0.01) of DNA synthesis in this cell line as determined by [3H]thymidine incorporation into DNA. Tetradecanoylphorbol Acetate 98-101 epidermal growth factor Homo sapiens 0-3 8081876-3 1993 EGF-induced phosphorylation and communication inhibition were retained in cells pretreated with phorbol 12-myristate 13-acetate (PMA) to deplete protein kinase C.

Tetradecanoylphorbol Acetate 129-132 epidermal growth factor Homo sapiens 191-194 1707036-4 1991 Addition of fetuin or epidermal growth factor (EGF) to incubates with serum-deprived cells increased the ability of TPA to affect growth, but addition of platelet-derived growth factor (PDGF), transforming growth factor beta (TGF-beta) or retinoic acid (RA) was without effect. Tetradecanoylphorbol Acetate 116-119 epidermal growth factor Homo sapiens 22-45 1445344-5 1992 IGF-I and EGF stimulated the transcriptional activity dependent on the phorbol 12-myristate 13-acetate-responsive element (TRE) to the same extent, when measured by the chloramphenicol acetyl transferase activity of a transiently transfected multiple TRE construct. Tetradecanoylphorbol Acetate 71-102 epidermal growth factor Homo sapiens 10-13 1427596-10 1992 However, this effect of EGF was counteracted by the pretreatment with TPA or H-7. Tetradecanoylphorbol Acetate 70-73 epidermal growth factor Homo sapiens 24-27 1915667-3 1991 In this paper we show that epidermal growth factor (EGF)- and 12-O-tetradecanoyl-phorbol-13-acetate (TPA)-induced expression of the c-fos and c-jun protooncogenes is decreased in microgravity, while no effect of gravity changes was observed on A23187- and forskolin-induced expression of these genes. Tetradecanoylphorbol Acetate 101-104 epidermal growth factor Homo sapiens 27-50 1915667-3 1991 In this paper we show that epidermal growth factor (EGF)- and 12-O-tetradecanoyl-phorbol-13-acetate (TPA)-induced expression of the c-fos and c-jun protooncogenes is decreased in microgravity, while no effect of gravity changes was observed on A23187- and forskolin-induced expression of these genes. Tetradecanoylphorbol Acetate 101-104 epidermal growth factor Homo sapiens 52-55 8424125-6 1993 Like 12-O-Tetradecanoly phorbol-13-acetate (TPA), a PK-C activator which also enhances EGF-stimulated growth of MEC, linoleate can phosphorylate a 40-42 KD protein. Tetradecanoylphorbol Acetate 44-47 epidermal growth factor Homo sapiens 87-90 11537644-4 1992 In addition, we have investigated signalling pathways as induced by 12-O-tetradecanoylphorbol-13-acetate (TPA), forskolin, and A23187 that bypass the EGF receptor, but mimic the partial activation of signal transduction pathways. Tetradecanoylphorbol Acetate 68-104 epidermal growth factor Homo sapiens 150-153 11537644-11 1992 These observations demonstrate that gravity affects specific components in the EGF-induced signal transduction circuitry, in particular the protein kinase C pathway which is common to EGF and TPA activated intracellular signalling. Tetradecanoylphorbol Acetate 192-195 epidermal growth factor Homo sapiens 79-82 1738590-4 1992 Induction of jun B can be mimicked in wild type P19 EC cells by the synergistic action of the phorbol ester TPA and the calcium ionophore A23187, through activation of signal transduction pathways, that are activated simultaneously by EGF. Tetradecanoylphorbol Acetate 108-111 epidermal growth factor Homo sapiens 235-238 1850101-7 1991 After both 1 and 24 h, tyrphostin was a less effective inhibitor of tyrosine kinase activity than the potent tumor promoter 12-O-tetradecanoyl phorbol-13-acetate, which almost completely blocked EGF receptor autophosphorylation. Tetradecanoylphorbol Acetate 124-161 epidermal growth factor Homo sapiens 195-198 1707036-4 1991 Addition of fetuin or epidermal growth factor (EGF) to incubates with serum-deprived cells increased the ability of TPA to affect growth, but addition of platelet-derived growth factor (PDGF), transforming growth factor beta (TGF-beta) or retinoic acid (RA) was without effect. Tetradecanoylphorbol Acetate 116-119 epidermal growth factor Homo sapiens 47-50 2283681-5 1990 Low concentrations of TPA (2 x 10(-10) M) had no effect on Ca2+ release due to EGF, TGR-alpha or bradykinin but resulted in a rapid return of [Ca2+]i to baseline levels for EGF or TGF-alpha. Tetradecanoylphorbol Acetate 22-25 epidermal growth factor Homo sapiens 173-176 2171499-3 1990 Both the Ca2+ ionophore ionomycin and the tumour promotor tetradecanoylphorbol acetate (TPA), added shortly before EGF, inhibit EGF receptor protein tyrosine kinase activity in intact cells. Tetradecanoylphorbol Acetate 58-86 epidermal growth factor Homo sapiens 115-118 2171499-3 1990 Both the Ca2+ ionophore ionomycin and the tumour promotor tetradecanoylphorbol acetate (TPA), added shortly before EGF, inhibit EGF receptor protein tyrosine kinase activity in intact cells. Tetradecanoylphorbol Acetate 88-91 epidermal growth factor Homo sapiens 115-118 1985972-4 1991 The study of EGF binding to only low affinity receptors was performed with cells pretreated with the phorbol ester phorbol 12-myristate 13-acetate, which induces a conversion of high affinity receptors to low affinity receptors. Tetradecanoylphorbol Acetate 115-146 epidermal growth factor Homo sapiens 13-16 1701695-6 1990 The EGF-dependent growth stimulation in ER11 cells was inhibited by 12-O-tetradecanoylphorbol 13-acetate (TPA). Tetradecanoylphorbol Acetate 68-104 epidermal growth factor Homo sapiens 4-7 1701695-6 1990 The EGF-dependent growth stimulation in ER11 cells was inhibited by 12-O-tetradecanoylphorbol 13-acetate (TPA). Tetradecanoylphorbol Acetate 106-109 epidermal growth factor Homo sapiens 4-7 1701695-7 1990 Exposure of NA and ER11 cells to TPA for 30 h resulted in the down-regulation of protein kinase C. In these protein kinase C-deficient cells, EGF was able to activate autophosphorylation of the EGF receptor. Tetradecanoylphorbol Acetate 33-36 epidermal growth factor Homo sapiens 142-145 1701695-7 1990 Exposure of NA and ER11 cells to TPA for 30 h resulted in the down-regulation of protein kinase C. In these protein kinase C-deficient cells, EGF was able to activate autophosphorylation of the EGF receptor. Tetradecanoylphorbol Acetate 33-36 epidermal growth factor Homo sapiens 194-197 2637248-1 1989 Tumor promoting phorbol esters, 12-O-tetradecanoylphorbol-13-acetate (TPA) and phorbol-12,13-dibutyrate (PDBu), significantly enhanced the growth of human gastric cancer cell line TMK-1, whilst activating protein kinase C. The time course of 125I-epidermal growth factor (EGF) binding to TMK-1 cells after TPA treatment showed a decrease in the number of EGF receptors on TMK-1 cells within 3 hr. Tetradecanoylphorbol Acetate 32-68 epidermal growth factor Homo sapiens 242-270 2283681-6 1990 Addition of the PKC inhibitor staurosporine (1 and 10 nM) completely inhibited the action of TPA on EGF-induced [Ca2+]i changes. Tetradecanoylphorbol Acetate 93-96 epidermal growth factor Homo sapiens 100-103 2283681-8 1990 Down-regulation of PKC by overnight incubation with 0.1 or 1 microM TPA produced the converse effect, namely prolonged Ca2+ entry following stimulation with EGF or TGF-alpha. Tetradecanoylphorbol Acetate 68-71 epidermal growth factor Homo sapiens 157-160 2283681-13 1990 A431 cells treated with higher concentrations of TPA (5 x 10(-8) M) inhibited not only Ca2+ entry but also Ca2+ release due to EGF/TGF-alpha but had no effect on bradykinin-mediated Ca2+ release, suggesting differences in the regulation of the intracellular stores responsive to these two classes of agonists. Tetradecanoylphorbol Acetate 49-52 epidermal growth factor Homo sapiens 127-130 2107492-0 1990 2-Aminopurine abolishes EGF- and TPA-stimulated pp33 phosphorylation and c-fos induction without affecting the activation of protein kinase C. Epidermal Growth Factor (EGF) and Tetradecanoyl Phorbol Acetate (TPA) initiate signalling cascades in C3H 10T1/2 fibroblasts by primarily activating distinct protein kinases, the EGF receptor tyrosine kinase and protein kinase C respectively; there is no signal crossover at the initiation of signalling.

Tetradecanoylphorbol Acetate 208-211 epidermal growth factor Homo sapiens 143-166 2107492-5 1990 Further, we show here that although EGF- and TPA-stimulated induction of c-fos is abolished by 2-aminopurine, the appearance of TRE-binding activity in nuclear extracts of stimulated cells is unaffected, suggesting that EGF- and TPA-stimulated induction of TRE-binding activity utilises existing proteins and is not dependent on fresh c-FOS synthesis. Tetradecanoylphorbol Acetate 45-48 epidermal growth factor Homo sapiens 220-223 2169292-3 1990 Downmodulation of EGF receptors by 12-O-tetradecanoylphorbol 13-acetate (TPA) is also observed.

Tetradecanoylphorbol Acetate 73-76 epidermal growth factor Homo sapiens 18-21 2637248-1 1989 Tumor promoting phorbol esters, 12-O-tetradecanoylphorbol-13-acetate (TPA) and phorbol-12,13-dibutyrate (PDBu), significantly enhanced the growth of human gastric cancer cell line TMK-1, whilst activating protein kinase C. The time course of 125I-epidermal growth factor (EGF) binding to TMK-1 cells after TPA treatment showed a decrease in the number of EGF receptors on TMK-1 cells within 3 hr. Tetradecanoylphorbol Acetate 32-68 epidermal growth factor Homo sapiens 272-275 2637248-1 1989 Tumor promoting phorbol esters, 12-O-tetradecanoylphorbol-13-acetate (TPA) and phorbol-12,13-dibutyrate (PDBu), significantly enhanced the growth of human gastric cancer cell line TMK-1, whilst activating protein kinase C. The time course of 125I-epidermal growth factor (EGF) binding to TMK-1 cells after TPA treatment showed a decrease in the number of EGF receptors on TMK-1 cells within 3 hr. Tetradecanoylphorbol Acetate 32-68 epidermal growth factor Homo sapiens 355-358 2637248-1 1989 Tumor promoting phorbol esters, 12-O-tetradecanoylphorbol-13-acetate (TPA) and phorbol-12,13-dibutyrate (PDBu), significantly enhanced the growth of human gastric cancer cell line TMK-1, whilst activating protein kinase C.

The time course of 125I-epidermal growth factor (EGF) binding to TMK-1 cells after TPA treatment showed a decrease in the number of EGF receptors on TMK-1 cells within 3 hr. Tetradecanoylphorbol Acetate 70-73 epidermal growth factor Homo sapiens 272-275 2637248-1 1989 Tumor promoting phorbol esters, 12-O-tetradecanoylphorbol-13-acetate (TPA) and phorbol-12,13-dibutyrate (PDBu), significantly enhanced the growth of human gastric cancer cell line TMK-1, whilst activating protein kinase C. The time course of 125I-epidermal growth factor (EGF) binding to TMK-1 cells after TPA treatment showed a decrease in the number of EGF receptors on TMK-1 cells within 3 hr. Tetradecanoylphorbol Acetate 70-73 epidermal growth factor Homo sapiens 355-358 2637248-2 1989 Autophosphorylation of EGF receptor decreased in accordance with the decrease of EGF binding by TPA treatment. Tetradecanoylphorbol Acetate 96-99 epidermal growth factor Homo sapiens 23-26 2637248-2 1989 Autophosphorylation of EGF receptor decreased in accordance with the decrease of EGF binding by TPA treatment. Tetradecanoylphorbol Acetate 96-99 epidermal growth factor Homo sapiens 81-84 2637248-3 1989 Scatchard plot analysis of TMK-1 cells after TPA treatment showed that high affinity EGF receptor disappeared at 3hr but the number of EGF receptors increased at 24 hr. Tetradecanoylphorbol Acetate 45-48 epidermal growth factor Homo sapiens 85-88 2851595-6 1988 Potentiation of the action of EGF by the tumor promoter 12-O-tetradecanoyl-phorbol-13-acetate (TPA), indicates that activation of protein kinase C and an influx of Ca2+ share a common mechanism for initiating DNA synthesis. Tetradecanoylphorbol Acetate 56-93 epidermal growth factor Homo sapiens 30-33 2549060-7 1989 Desensitization to EGF was observed in cells in which protein kinase C had been down-regulated by prolonged treatment with 12-O-tetradecanoylphorbol-13-acetate, implying that EGF receptor desensitization is independent of protein kinase C.
