cystadenocarcinoma/glutathione

The effects of platinum-based drugs are controlled by genes that are involved in DNA detoxification, including glutathione S-transferase (GST)P1 and GSTM1, which have been associated with increased benefits in the chemotherapeutic treatment of patients with ovarian cancer. The present study assessed

The effects of D,L-buthionine-S, R-sulphoximine (BSO) on the cellular glutathione (GSH) levels and cis-diamminedichloroplatinum (II) (CDDP) sensitivity of human ovarian cancer cell lines (HRA, KK and MH) with different sensitivity to CDDP were examined. HRA cells were derived from ascites of a

A cis-diamminedichloroplatinum (II) (CDDP)-resistant cell line (NOS2CR) demonstrated 7.4-fold greater resistance to CDDP compared with the parental cell line (NOS2) established from a patient with serous cystadenocarcinoma of the ovary. We investigated the role of enzyme systems associated with

Neoplasms of the epididymis are uncommon, and malignant tumors are extremely rare. We report a case of clear cell papillary cystadenocarcinoma of the epididymis presenting with a long history of painless scrotal mass on the left side. Immunohistochemical markers for clear cell renal cell carcinoma

OBJECTIVE To explore the association between Glutathione S-transferase (GST) -mu expression and clinicopathologic features in ovarian tumors. METHODS Immunohistochemical study was made to investigate GST-mu expression in diverse ovarian tumors. RESULTS All 75 ovarian tumors expressed GST-mu. There

Patients with progressive ovarian cancer who underwent a remission-induction therapy in our department; intermittent chemotherapy (IC) of CDDP was performed every 3 months, and good outcome has been obtained. However, ineffective cases are sporadically seen. As long-term prognostic factors

A newly synthesized calmodulin antagonist, (S)-P-(2-aminoethyloxy)-N-[2-(4-benzyloxy-carbonylpiperazinyl++ +)-1-(P-methoxybenzyl)ethyl]-N-methylbenzenesulfonamide dihydrochloride (W-77), acts as a calcium-independent uncompetitive antagonist which binds to glutathione-S-transferase (GST). We

To investigate differences in resistance to cis-diamminedichloroplatinum(II) (CDDP) and diammine (1,1-cyclobutanecarboxylato)platinum(II) (CBDCA), and their newly developed derivative, ((-)-(R)-2-aminomethylpyrrolidine (1,1-cyclobutanedicarboxylato)platinum (II) (DWA2114R), four types of resistant

It is known that some cancers show platinum complex resistance and that others show platinum complex sensitivity among ovarian cancers. Oxaliplatin (cis-[oxalato[trans-l-1, 2-diamino-cyclohexane] platinum[II]]; l-OHP), an active anti-cancer agent consisting of platinum, inhibits RNA synthesis and

The intracellular metabolism and cytotoxic effects of Ara-C and 2'-difluorodeoxycytidine (dFdC or Gemcitabine) administered with or without deoxycytidine (dCyd) were examined in cisplatin-resistant (2008/C13) and -sensitive (2008) human ovarian cystadenocarcinoma cells. Compared to 2008 cells,
