Fig. 3From: Reduced USP39 expression inhibits malignant proliferation of medullary thyroid carcinoma in vitroKnockdown of USP39 down-regulates G2/M-related cell cycle regulators. a Quantitative analysis of Cyclin B1 expression alteration in TT cells was assessed by qRT-PCR. β-actin gene was used as an internal control. b Representative immunoblot showing CDK1 and p-CDK1(Tyr15) protein levels determined in TT cells. GAPDH protein was used as an internal control. Each point represents the mean ± SD of three independent repeats. The significance was determined by t test. *p < 0.05Back to article page
