MiR‐608 is a nonconserved miRNA derived from an intron of human SEMA4G (semaphorin 4G) gene located at chromosome 10q24.31.8 It has been implicated in many malignancies, such as pancreatic cancer, bladder cancer, ovarian cancer, and lung adenocarcinoma, where miR‐608 inhibits their proliferation and progression.9, 10, 11, 12 However, the particular functions of miR‐608 in PCa have not been investigated. This evidence concerns the gene SEMA4G and urinary bladder cancer.
