Camptothecin 36-48 transformation related protein 53, pseudogene Mus musculus 106-109 8932379-5 1996 We now show that a series of topoisomerase poisons (actinomycin D, camptothecin, daunomycin and etoposide) also activate NF-kappaB (NFKB1/RelA dimer) in ACH-2 and CEM cells.

Camptothecin 26-38 cyclin B1 Homo sapiens 123-132 8895510-5 1996 However, with camptothecin or etoposide treatment, while the accumulation of cyclin B1 protein was delayed, its levels eventually surpassed peak levels seen in control cells, in spite of the fact that cells were still blocked in G2. Camptothecin 14-26 cyclin B1 Homo sapiens 77-86 8875976-7 1996 Moreover, when the DNA damage-inducing drugs etoposide or camptothecin were added to the cells, a further stimulation of kinase activity was observed following growth at 28 degrees C, but not 38 degrees C.

Camptothecin 35-47 DNA topoisomerase I Homo sapiens 78-97 8917343-0 1996 Induction of tumor necrosis factor by a camptothecin derivative, irinotecan, in mice and human mononuclear cells.

Camptothecin 20-23 DNA segment, 20S Mus musculus 0-18 8639538-5 1996 In vitro experiments with purified recombinant proteins show that p53 increases the catalytic activities of topoisomerase I as measured by relaxation of supercoiled DNA, stabilization of the covalent topoisomerase I-DNA complex (in the presence of camptothecin), and phosphorylation of SR protein splicing factor ASF/SF2. Camptothecin 248-260 tumor protein p53 Homo sapiens 66-69 8634449-6 1996 The results also demonstrate the activation and cleavage of PKCdelta (1) is inhibited by expression of antiapoptotic proteins, and (2) is induced by camptothecin (CAM) and mitomycin C (MMC). Camptothecin 163-166 protein kinase C delta Homo sapiens 60-68 8838651-9 1996 When HL60 cells were stimulated by diverse apoptosis inducers such as camptothecin, staurosporine, cycloheximide, and A23187, the extent of NuMA cleavage to produce a 180 kDa product was comparable with the degree of oligonucleosomal laddering.

Camptothecin 62-74 interleukin 1 alpha Homo sapiens 14-33 8632759-3 1996 Studies indicated that IL-1 alpha significantly increased topoisomerase I-catalyzed camptothecin-induced DNA cleavable complexes in the ovarian cell line, which was not due increased intracellular camptothecin as IL-1 alpha failed to effect cellular uptake of camptothecin. Camptothecin 84-96 interleukin 1 alpha Homo sapiens 23-33 8632759-6 1996 Because camptothecins are active against solid tumors in vivo, combinations of IL-1 alpha with these active drugs may lead to more effective treatment of ovarian cancers in the clinic. Camptothecin 8-21 interleukin 1 alpha Homo sapiens 79-89 8565133-1 1996 Camptothecin is a widely used anti-tumor drug that specifically inhibits DNA topoisomerase I. Camptothecin 0-12 DNA topoisomerase 1 Cricetulus griseus 73-92 8565133-3 1996 We have assessed the effects of camptothecin on RNA polymerase II transcription from the dihydrofolate reductase (DHFR) gene in Chinese hamster ovary (CHO) cells.

Camptothecin 32-44 dihydrofolate reductase Cricetulus griseus 114-118 8565133-4 1996 Using in vivo [3H]uridine pulse labeling and in vitro nuclear run-on techniques to estimate relative rates of transcription, it was found that camptothecin stimulated RNA synthesis from promoter-proximal sequences of the DHFR gene, while transcription from promoter-distal sequences was reduced. Camptothecin 143-155 dihydrofolate reductase Cricetulus griseus 221-225 8565133-6 1996 The effect of camptothecin on transcription was reversible, resulting in a wave of RNA synthesis recovery in a 5" to 3" direction through the DHFR gene following a chase with camptothecin-free medium.

Camptothecin 155-167 bifunctional glycerol-3-phosphate/glycerone-phosphate O-acyltransferase SCT1 Saccharomyces cerevisiae S288C 227-231 7603986-4 1995 Mutant SCT1 cells expressed DNA topoisomerase I protein of similar specific activity and camptothecin sensitivity to that of congenic, drug-sensitive sct1 cells, yet were resistant to camptothecin-mediated lethality. Camptothecin 89-101 bifunctional glycerol-3-phosphate/glycerone-phosphate O-acyltransferase SCT1 Saccharomyces cerevisiae S288C 7-11 7603986-4 1995 Mutant SCT1 cells expressed DNA topoisomerase I protein of similar specific activity and camptothecin sensitivity to that of congenic, drug-sensitive sct1 cells, yet were resistant to camptothecin-mediated lethality.

Camptothecin 103-115 bifunctional glycerol-3-phosphate/glycerone-phosphate O-acyltransferase SCT1 Saccharomyces cerevisiae S288C 0-4 7603986-6 1995 SCT1 cell sensitivity to other DNA-damaging agents suggests that alterations in SCT1 function suppress camptothecin-induced DNA damage produced in the presence of yeast DNA topoisomerase I. Camptothecin 103-115 bifunctional glycerol-3-phosphate/glycerone-phosphate O-acyltransferase SCT1 Saccharomyces cerevisiae S288C 80-84 7766631-2 1995 Two water-soluble camptothecin derivatives are in clinical trial, and their anticancer activity appears promising: topotecan and CPT-11.

Camptothecin 132-144 nucleophosmin 1 Homo sapiens 13-16 7812949-1 1995 We have studied changes in cyclin A- and B1-dependent kinases during apoptosis induced in human promyelocytic leukemia (HL60) cells treated with the topoisomerase I inhibitor camptothecin. Camptothecin 175-187 cyclin A2 Homo sapiens 27-35 7699706-2 1995 The activity of these compounds may be attributed to their rigid, planar geometry, and an attempt was made to correlate the SAR in this series to known attributes of camptothecin.

Camptothecin 157-169 vitamin D receptor Homo sapiens 64-67 7690896-3 1993 A similar important role of BrdUrd in SCE induction has been reported in the cases of benzamide (BA) (Natarajan et al., 1981) and camptothecin (CPT) (Zhao et al., 1992), which are inhibitors of poly(ADP-ribose)polymerase and DNA topoisomerase I (topo I), respectively.

Camptothecin 119-122 DNA topoisomerase 1 Cricetulus griseus 134-153 8402636-6 1993 When added simultaneously with CAM or TPT, CAF prevented both effects. Camptothecin 31-34 lysine acetyltransferase 2B Homo sapiens 43-46 8402636-10 1993 Thus, the ability of CAF to protect HL-60 cells against the cell kinetic effects of CAM or TPT, as in the case of DNA intercalating topoisomerase II inhibitors, is most likely due to formation of complexes between CAF and these aromatic molecules, which result in reducing the effective concentration of the free form of these drugs available to the cells.
