Figure Lengend Snippet: mRNA expression analysis by RT-qPCR, and assessment of self-renewal and tumor growth in H460-derived SFCs. (A) BEP2D, H460 and A549 cells were treated with DFOG (0–20 µM) for 48 h, and cell viability was assessed using a Cell Counting Kit-8 assay. H460 and A549 cells were treated with DFOG (5 µM) for 24 h. RT-qPCR was used to evaluate the effects of DFOG (5 µM) on tumor-suppressive miRNAs, including miR-671-5p, miR-148a-3p, miR-340-5p, miR-342-3p, miR-34a-5p and miR-152-3p in (B) H460 and (C) A549 cells.
