BzATP-induced activation of ERK pathway in U87 and U251 glioma cells. (a) Representative immunoblots showing the changes in ERK, p- ERK, and PCNA protein expression in control (Ctr), BzATP (100 μM), and BzATP + BBG-treated U87 (left) and U251 (right) cells. (b, c) Bar charts summarizing the average densitometric quantification of immunoreactive bands of ERK, p-ERK, and PCNA proteins of U87 (b) and U251. (c) Cells under different conditions, for each group. and versus Ctr; and versus BzATP group.
