In addition, western blot analysis revealed that the protein levels of endogenous stem genes of NSCLC CSCs (Oct4 and ABCG2) in cells treated with oe-lncRNA MBNL1-AS1 were lower than the protein levels observed in cells treated with oe-NC (p < 0.05, Fig. 3l). This evidence concerns the gene ABCG2 and non-small cell lung carcinoma.
