miR-26a enhances miRNA biogenesis by targeting Lin28B and Zcchc11 to suppress tumor growth and metastasis

Human cancers often exhibit attenuated microRNA (miRNA) biogenesis and global underexpression of miRNAs; thus, targeting the miRNA biogenesis pathway represents a novel strategy for cancer therapy. Here, we report that miR-26a enhances miRNA biogenesis, which acts as a common mechanism partially accounting for miR-26a function in diverse cancers including melanoma, prostate and liver cancer. miR-26a was broadly reduced in multiple cancers, and...
