Mechanically, Yang et al. reported that in lung adenocarcinoma cells from Kras/Tp53-mutant animals and human lung cancer cell lines, ZEB1 activates PI3K by depressing miR-200 targets, including amphiregulin (AREG), betacellulin (BTC), and GATA6 [33]. The gene discussed is BTC; the disease is lung adenocarcinoma.
