TMZ and RG3 additively inhibited rat C6 glioma cell proliferation. Cells were seeded in 24 well plates and treated with TMZ and/or RG3 for designated time and doses. a TMZ inhibited C6 glioma cell proliferation in a time and dose dependent manner. b RG3 inhibited C6 glioma cell proliferation in a time and dose dependent way. c TMZ and RG3 additively inhibited proliferation of C6 glioma cells. Bars with different letters indicate significant difference (P < 0.05) based on post-hoc Tukey analysis
