Long non-coding RNA ANRIL promotes carcinogenesis via sponging miR-199a in triple-negative breast cancer.

Triple-negative breast cancer (TNBC) is a complex breast cancer subtype characterized by the absence of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (Her2). Long non-coding RNA (lncRNA) antisense non-coding RNA in the INK4 locus (ANRIL) has been verified as oncogenic molecular in series of tumors, however, the role of ANRIL in TNBC carcinogenesis is still unclear. The purpose of present study is to investigate the expression and in-depth regulation of ANRIL on TNBC tumorigenesis.
