AKT1 and lung cancer: Overexpression of the lncRNA BC087858 correlates with lower survival rate, under TKIs-based therapy, while siRNAs genetic silencing assays in gefitinib-resistant lung cancer cells promoted gefitinib-sensibility, associated to E-cadherin gene overexpression, and low gene expression for Vimentin, ZEB1, and Snail, as well as a decreased level of phosphorylated EGFR-, AKT-, and ERK.
