[Effect of astrocyte-conditioned medium on tert-butyl hydroperoxide-induced apoptosis of PC12 cells].

Objective: To investigate the effect of astrocyte-conditioned medium (ACM) on PC12 cell apoptosis induced by reactive oxygen species tert-butyl hydroperoxide (tbOOH).

Methods: PC12 cells attacked by tbOOH were cultured with Sprague Dawley rat cerebral cortex ACM, and the cell apoptosis was observed by fluorescent microscopy and transmission electron microscopy. The cell apoptosis rate was evaluated by flow cytometry and malondialdehyde (MDA) concentration measured using thiobarbituric acid (TBA)-reacting substances (TRABS).

Result: TbOOH induced PC12 cell apoptosis, and ACM significantly decreased the apoptosis rate and MDA concentration in tbOOH-treated cells.

Conclusion: ACM may increase the anti-oxidation capacity of PC12 cells and inhibit cell apoptosis induced by tbOOH.
