Immunohistochemistry for the active form of GSK3β in mouse brain tumor. The level of pGSK3βY216 was not affected by kenpaullone or TMZ alone while the combination therapy markedly decreased pGSK3βY216 in the tumor cells. Specimens of metastatic breast cancer were used as a positive control for immunostaining. Scale bar = 100 μm. Ctrl: tumor in a mouse treated with DMSO; KP: kenpaullone. PC: positive control and NC: negative control (non-immune rabbit IgG) for immunostaining of pGSK3βY216.
