Aphidicolin 36-47 carbonic anhydrase 3 Homo sapiens 83-86 7828276-8 1995 Therefore, the resistance to cisplatin in human larynx carcinoma CA3 and CK2 cells can be partially reversed by amphotericin B and aphidicolin. Aphidicolin 131-142 carbonic anhydrase 3 Homo sapiens 65-68 7533524-9 1994 In addition, the positioning of separate 3p14.2 aphidicolin-induced breakpoints suggests that FRA3B may represent a region rather than a single site.

Aphidicolin 69-80 gap junction protein, alpha 1 Mus musculus 82-86 7806217-2 1994 The common fragile site at 3p14.2 (FRA3B) is the most sensitive site on normal human chromosomes to breakage when DNA replication is perturbed by aphidicolin or folate stress. Aphidicolin 146-157 fragile histidine triad diadenosine triphosphatase Homo sapiens 35-40 7523194-6 1994 A comparison of the effects of aphidicolin, oryzalin and olomoucine suggests that in the Arabidopsis cell suspension culture, a cdc2/cdk2-like kinase is activated at a restriction point in late G1.

Aphidicolin 49-60 haptoglobin-related protein Homo sapiens 139-142 8261433-6 1994 Analysis of cell cycle distribution in aphidicolin-synchronized SSR1-positive NB cells indicated that this inhibitory effect is partially mediated by a transient accumulation in G0-G1. Aphidicolin 39-50 signal sequence receptor subunit 1 Homo sapiens 64-68 8137287-4 1994 This effect was abolished by cotreatment with the DNA polymerase alpha inhibitor aphidicolin. Aphidicolin 81-92 DNA polymerase alpha 1, catalytic subunit Homo sapiens 50-70 8359227-3 1993 On the other hand, aphidicolin, which is a potent inhibitor of DNA replication, inhibited GP IIb/IIIa or IIIa expression, but induced the expression of erythroid phenotypes. Aphidicolin 19-30 integrin subunit alpha 2b Homo sapiens 90-96 8254211-15 1994 These results were confirmed by cell cycle blockade studies with aphidicolin and nocodazole wherein TTK protein levels are not detected in cells in G1 and are readily detectable in cells in the S and G2 phases of the cell cycle. Aphidicolin 65-76 TTK protein kinase Homo sapiens 100-103 8267640-1 1993 We investigated the effect of aphidicolin, an inhibitor of DNA polymerase alpha and delta, on the induction of apoptosis by arabinosyl nucleosides in a human promyelocytic leukemia cell line, HL-60.

Aphidicolin 230-241 Bardet-Biedl syndrome 9 Homo sapiens 208-211 18613241-7 1993 Also, when cell cycle progression was stopped at the S phase by addition of aphidicolin, beta-galactosidase content in single cells was higher than that in exponential phase or plateau phase cells and increased with increasing culture time. Aphidicolin 76-87 beta-galactosidase Cricetulus griseus 89-107 8376804-7 1993 Aphidicolin inhibited repair and consistently sensitized to TNF cytotoxicity, decreasing the ID50 for TNF at least 10- to 50-fold.

Aphidicolin 247-258 DNA polymerase alpha 1, catalytic subunit Homo sapiens 200-216 1390903-4 1992 Cells arrested in late G1 by aphidicolin have abundant p58cyclin A and phosphorylated p34cdc2. Aphidicolin 29-40 cyclin dependent kinase 1 Homo sapiens 86-93 1517236-11 1992 Moreover, the increased phosphorylation of cdk2 in aphidicolin-blocked extracts and the ability of cdc25 to mediate cdk2 dephosphorylation in vitro suggest the possibility that cdk2 is part of the mechanism ensuring mitosis is not initiated until completion of DNA replication.

Aphidicolin 93-104 glycosylphosphatidylinositol specific phospholipase D1 Homo sapiens 66-69 1573280-2 1992 [3H]dTTP incorporation in isolated nuclei was shown to be representative of replicative DNA synthesis by evidence that (i) incorporation was dependent on ATP and all four nucleoside precursors, (ii) incorporation was inhibited greater than 97% by aphidicolin, a specific inhibitor of DNA polymerase alpha and delta, and (iii) the DNase I-sensitive product banded in neutral CsCl at a density indicative of replicative DNA.

Aphidicolin 55-66 DNA polymerase alpha 1, catalytic subunit Homo sapiens 84-104 1753100-12 1991 The unexpected toxicity of aphidicolin toward normal human monocytes may be attributable to their high rate of spontaneous DNA strand break formation, to the importance of DNA polymerase-alpha for DNA repair in these cells, and to their minute dCTP pools. Aphidicolin 27-38 DNA polymerase alpha 1, catalytic subunit Homo sapiens 172-192 1724341-5 1991 However, pretreatment with aphidicolin (3 x 10(-5) M), a potent inhibitor of DNA synthesis, blocked the effect of acid FGF and diminished the effect of bFGF. Aphidicolin 27-38 fibroblast growth factor 2 Rattus norvegicus 152-156 1935798-9 1991 The ability of IL-1 alpha to increase CDP in the presence of cortisol was the same in the presence or absence of indomethacin, an inhibitor of PGE2 synthesis, or aphidicholin (30 microM), an inhibitor of DNA synthesis, indicating that the reversal was neither PG mediated nor dependent on cell proliferation.

Aphidicolin 36-47 proliferating cell nuclear antigen Homo sapiens 117-121 1706219-9 1991 The effects of ara-CTP and aphidicolin on these enzymes were opposite those seen with Fara-ATP, since 50% inhibitory concentrations of either ara-CTP or aphidicolin for DNA polymerases alpha/delta did not inhibit polydeoxythymidylate primase activity. Aphidicolin 27-38 DNA polymerase alpha 1, catalytic subunit Homo sapiens 169-190 1706219-9 1991 The effects of ara-CTP and aphidicolin on these enzymes were opposite those seen with Fara-ATP, since 50% inhibitory concentrations of either ara-CTP or aphidicolin for DNA polymerases alpha/delta did not inhibit polydeoxythymidylate primase activity.
