Fig. 2From: Overexpression of RPN2 suppresses radiosensitivity of glioma cells by activating STAT3 signal transductionRPN2 was upregulated in radioresistant GBM cells. a The survival of parental and radioresistant U87 (upper) and A172 (lower) cells treated with 5 GY radiation. b The apoptosis of parental and radioresistant U87 (upper) and A172 (lower) cells treated with 5 GY radiation. c The growth of parental and radioresistant U87 (upper) and A172 (lower) cells. d The expression of RPN2 and CASP3 in parental and radioresistant U87 (left) and A172 (right) cells treated with 5 GY radiation. e The mRNA level of RPN2 in parental and radioresistant U87 and A172 cells. f, g The protein (f) and mRNA (g) level of RPN2 in the indicated cells. Each experiment was performed for 3 times. *, p < 0.05; **, p < 0.01Back to article page
