TGFB1 and breast cancer: The upregulation of lncRNA-ATB (long non-coding RNA activated by TGF-Beta) [40], TINCR (Tissue differentiation-inducing non-protein coding RNA) [41], UCA1 [42], AGAP2-ASI (Arf GAP with GTP-binding protein-like domain, Ankyrin repeat, and PH domain 2) [43], and the downregulation of GAS5 (growth arrest-specific 5) [44] are strongly involved in acquiring trastuzumab resistance in BC patients.
