TGFB1 and breast cancer: Major studies showed that lncRNA LINC01186 and lncRNA‐HIT (HOXA transcript induced by TGF‐β) are mediators of TGF‐β signalling in lung and breast cancer cells, respectively, playing a significant role in the regulation of lung and breast cancer cell migration and invasion (Hao et al., 2017; Richards et al., 2015).
