Fig. 6From: USP39 promotes malignant proliferation and angiogenesis of renal cell carcinoma by inhibiting VEGF-A165b alternative splicing via regulating SRSF1 and SRPK1The expression level of USP39 affects the interaction between SRPK1 and SRSF1 and the effect of USP39 expression on VEGF-A variable splicing. A USP39 overexpression promoted the interaction between SRPK1 and SRSF1. B USP39 knockdown inhibited the interaction between SRPK1 and SRSF1. C USP39 overexpression promoted SRPK1 and SRPK1, and phosphorylation of SRSF1. D USP39 knockdown inhibited SRPK1 phosphorylation of SRSF1. E Total VEGF and VEGF-165b expression after USP39 knockdown or overexpression. The densitometry quantification of the western blots under each blotBack to article page
