ABA inducing autophagy independent of the mTOR signal pathway. a U87 and b A172 cells treated with DMSO (control), 3-MA (10 mM) and ABA (200 μM) for 24 h were analysed by Western blotting to measure the levels of total and phospho-Akt, total and phospho-mTOR, total and phospho-p85S6k, p70S6K and 4E-BP1. The data quantified by a densitometric analysis relative to GAPDH are shown on the right. **P < 0.01, n = 3
