MYLK and renal carcinoma: For example, circRNA ZNF609 functions as a competitive endogenous RNA to regulate FOXP4 expression by sponging miR-138-5p in renal carcinoma [35].CircRNA MYLK binds to miR-29a and promotes epithelial-mesenchymal transition and xenograft growth, angiogenesis, and metastasis of bladder cancer [36].
