Figure 3.
PACAP increases cystine uptake via a PKA-dependent pathway. 10 µM of the PKA inhibitor H89 completely blocked increases in cystine uptake induced by 24-hour PACAP (1 nM) treatment in primary mixed cortical cultures (n = 8–16). Data are expressed as mean ± SEM. * = P < 0.05 compared to control group.
