To further investigate the relationship between hsa-miR-10a-5p and UQCRB, we analyzed hsa-miR-10a-5p levels in cell lines of UQCRB expressing cancer, namely, HepG2 (human hepatocellular carcinoma), PC3 (human prostate cancer) and HCT116 cells (human colon cancer cell). This evidence concerns the gene UQCRB and prostate cancer.
