Pyrogallol as a glutathione depletor induces apoptosis in HeLa cells.

Pyrogallol, a polyphenol, is known to be a superoxide anion (O2(.-)) generator. We investigated the involvement of glutathione (GSH) and reactive oxygen species (ROS) in pyrogallol-induced HeLa cell death. We measured the changes of ROS levels, GSH levels, sub-G1 cells, annexin V/PI staining cells and mitochondria membrane potential (DeltaPsi m) in HeLa cells treated with pyrogallol and/or ROS ...

Auranofin induces apoptosis and necrosis in HeLa cells via oxidative stress and glutathione depletion.

Auranofin (Au), an inhibitor of thioredoxin reductase, is a known anti‑cancer drug. In the present study, the anti‑growth effect of Au on HeLa cervical cancer cells was examined in association with levels of reactive oxygen species (ROS) and glutathione (GSH). Au inhibited the growth of HeLa cells with an IC50 of ~2 µM at 24 h. This agent induced apoptosis and necrosis, accompanied by the cleav...

UV-induced apoptosis in resistant HeLa cells.

Recently, apoptosis (genetically programmed cell death) induced by UV has been documented in some cell culture models. However, the significance of apoptosis in UV-induced cytotoxicity and resistance is uncertain. In this study, we investigated the induction of apoptosis in HeLa cells and its role in acquired UV-resistance. The membrane receptor Fas was induced to assembly, and its immediate do...

Apoptosis 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...

Knockdown of mitofilin inhibits autophagy and facilitates starvation-induced apoptosis in HeLa cells

Objective(s): Mitofilin contributes to the maintenance of mitochondrial structure and functions. This study was undertaken to determine the mechanisms underlying its regulation of apoptosis.  Materials and Methods: Mitofilin was knockdowned by specific short hairpin RNA (shRNA) and the stable HeLa cell clone was selected. The autophagy a...
