Fig. 8From: Circular RNA circPLK1 promotes breast cancer cell proliferation, migration and invasion by regulating miR-4500/IGF1 axis CircPLK1 knockdown repressed tumor growth via upregulating miR-4500 and downregulating IGF1. Sh-NC or sh-circPLK1-transfected HCC38 cells were introduced into nude mice to establish mice model. a, b The data of tumor volume and weight were recorded and graphed. c The expression levels of circPLK1 and miR-4500 were measured by qRT-PCR in excised tumor tissues. d The protein expression of IGF1 was determined by western blot assay in excised tumor tissues. ***P < 0.001Back to article page
