Poly(ADP-ribose) glycohydrolase (PARG) is the primary enzyme responsible for the degradation of poly(ADP-ribose). PARG dysfunction sensitizes cells to alkylating agents and induces cell death; however, the details of this effect have not been fully elucidated. Here, we investigated the mechanism by which PARG deficiency leads to cell death in different cell(More)
Telmisartan, an angiotensin II receptor type 1 blocker, is often used as an antihypertension drug, and it has also been characterized as a peroxisome proliferator-activated receptor-gamma (PPARγ) ligand. The purpose of this study was to elucidate the antitumor effects of telmisartan on endometrial cancer cells. We treated three endometrial cancer cell lines(More)
KN-93, a membrane-permeant calcium/calmodulin-dependent kinase-selective inhibitor, induces apoptosis in some lines of human tumor cells. We investigated the effect of KN-93 in the choriocarcinoma cell line, BeWo. BeWo cells were treated with various concentrations of KN-93, and changes in cell growth, the cell cycle, apoptosis, and related parameters were(More)
This article has been retracted on request of the corresponding author. The author has identified errors affecting several figure panels in which the original data were processed inappropriately such that the panels in Figure 4: " Expression of the cell cycle-and apoptosis-related proteins treated with PK11195 in choriocarcinoma cells measured by Western(More)
The potential anticancer agent 1-(2-chlorophenyl-N-methylpropyl)-3-isoquinolinecarboxamide (PK11195), a translocator protein ligand (initially described as a ligand for the peripheral benzodiazepine receptor), induces apoptosis in some lines of human tumor cells. We investigated the effect of PK11195 in the choriocarcinoma cell line, BeWo. BeWo cells were(More)
Cucurbitacin D, a newly isolated triterpenoid cucurbitacin, has been found to possess anticancer effects. The purpose of this study was to elucidate the effects of cucurbitacin D on human endometrial and ovarian cancer cells. Human endometrial and ovarian cancer cells were treated with various concentrations of cucurbitacin D, and its effects on cell(More)
