The role of TARBP2 in the development and progression of cancers

TARBP2 is a RNA-binding protein (RBP) involved in miRNA processing and maturation. TARBP2 plays significant roles in many biological and pathological conditions, including viral expression of HIV-1, microsatellite instability, cancer stem cell properties, and tumor progression. Overexpression of TARBP2 was observed in many cancers such as prostate cancer, cutaneous malignant melanoma, and adrenocortical carcinoma. In addition, TARBP2 was also found to be downregulated in some cancers including colorectal cancer, gastric cancer, Ewing sarcoma, and upper urinary tract urothelial carcinoma. Therefore, whether TARBP2 functions as the tumor suppressor or tumor promoter is conflicting. In the present review, we provide an overview of current knowledge concerning the role of TARBP2 in tumor development and progression.
