BRMS1L and breast cancer: We aim to investigate the regulatory role of the lncRNA SATB2-AS1/miR-155-3p/BRMS1L axis in the biological functions of BC cells, and we inferred that lncRNA SATB2-AS1 may act as a competing endogenous RNA (ceRNA) to absorb miR-155-3p to affect the progression of BC by regulating BRMS1L.
