CEP55 and renal cell carcinoma: Treatment with miR-144 inhibitor or oe-CEP55 led to elevated CEP55 protein expression, which was annulled by additional treatment with si-circ_001287 (p < 0.05; Fig. 7e, f) The results suggest that downregulation of circ_001287 can decrease CEP55 expression by enhancing miR-144 expression, thus inhibiting the tumorigenicity of RCC cells in vivo.
