Ruthenium polypyridyl complexes as inducer of ROS-mediated apoptosis in cancer cells by targeting thioredoxin reductase.
TrxR is an NADPH-dependent selenoenzyme upregulated in a number of cancers. It plays a pivotal role in cancer progression and represents an increasingly attractive target for anticancer drugs. The limitations of cisplatin in cancer treatment have motivated the extensive investigation to other metal complexes, especially ruthenium (Ru) complexes. In this study, we present the in vitro biological...
متن کاملEF24 induces ROS-mediated apoptosis via targeting thioredoxin reductase 1 in gastric cancer cells
Gastric cancer (GC) is one of the leading causes of cancer mortality in the world, and finding novel agents for the treatment of advanced gastric cancer is of urgent need. Diphenyl difluoroketone (EF24), a molecule having structural similarity to curcumin, exhibits potent anti-tumor activities by arresting cell cycle and inducing apoptosis. Although EF24 demonstrates potent anticancer effïcacy ...
متن کاملHeparin-binding properties of selenium-containing thioredoxin reductase from HeLa cells and human lung adenocarcinoma cells.
Mammalian selenocysteine-containing thioredoxin reductase (TR) isolated from HeLa cells and from human lung adenocarcinoma cells was separated into two major enzyme species by heparin-agarose affinity chromatography. The low-affinity enzyme forms that were not retained on heparin agarose showed strong crossreactivity in immunoblot assays with anti-rat liver TR polyclonal antibodies, whereas the...
متن کاملSusceptibility of cholangiocarcinoma cells to parthenolide-induced apoptosis.
Cholangiocarcinomas are intrahepatic bile duct carcinomas that are known to have a poor prognosis. Sesquiterpene lactone parthenolide, which is the principal active component in medicinal plants, has been used to treat tumors. Parthenolide effectively induced apoptosis in all four cholangiocarcinoma cell lines in a dose-dependent manner. However, the sarcomatous SCK cells were more sensitive to...
متن کاملApoptosis induced by dioscin in Hela cells.
Dioscin, a saponin extracted from the root of Polygonatum Zanlanscianense Pamp, markedly inhibited proliferation of Hela cells. The results indicated that Hela cells underwent apoptosis in dose- and time-dependent manners when treated with Dioscin. Caspase-3, -8 and -9 activities were also detected. The low enzymatic activity of caspase-8 and high activity of caspase-9 showed that the mitochond...
