cPLA2 may not participate in t-BHP-induced apoptosis.

<p>Western blot analysis of cPLA2 expression during t-BHP-induced apoptosis. The cells were treated with or without Exendin-4 and then with t-BHP (200 µM for 24 hours) for different intervention times. The cells were then collected, and cell lysates were prepared and analyzed for cPLA2 and actin.
