Astaxanthin inhibiting oxidative stress damage of placental trophoblast cells in vitro.

This study aimed at exploring the potential effects of astaxanthin (ATX) on oxidative stress damaged placental trophoblast cell line HTR-8/SVneo. Oxidative stress-induced damaged through H2O2 treatment was checked by MTS CellTiter 96® cell viability, 2',7'-dichlorofluorescein diacetate (DCFH-DA) induced fluorescence, the level of the intracellular malondialdehyde (MDA), and the detection of glutathione peroxidase (GSH-Px), superoxide dismutase (SOD) and catalase (CAT). Different concentrations of ATX were applied, and then the proliferation rate, apoptotic percentage, cell cycle distribution, invasion test and relative biological function of the rescued cells were followed. We provide evidence that ATX had an anti-oxidative effect against oxidative stress induced by H2O2 on the trophoblast cell line and had beneficial role in promoting cell proliferation, inhibiting cell apoptosis, and inducing cell invasion.
