Immunohistochemical analysis in tissue sections of GFP-labeled tumors isolated from mice injected with H460 and H1975 cells transfected with NC-LV, OE-miR-330-3p-LV, or anti-miR-330-3p-LV. Relative quantitative analysis of immunohistochemistry for PCNA (a), cyclinD1 (b), apoptosis-related proteins (c, d), and DNA methyltransferases (e–g). All data were presented as mean of three independent experiments ± SD. *P < 0.05, **P < 0.01, #P < 0.001, one-way ANOVA test. (TIF 941 kb

miR-330-3p suppresses apoptosis of NSCLC cells. a Quantitative analysis of relative protein expression for Bcl-2 detected by western blotting. b Quantitative analysis of relative protein expression for Bax detected by western blotting in each group. c Quantitative analysis of relative protein expression for cleaved caspase3 detected by western blotting in each group. All data were presented as mean of three independent experiments ± SD. *P < 0.05, **P < 0.01, #P < 0.001, one-way ANOVA test. (TIF 523 kb

miR-330-3p is relevant to DNMT1 and DNMT3A in NSCLC cells. a DNMT1 protein expression was quantified by western blotting analysis. b Quantitative analysis of DNMT3A detected by western blotting. c DNMT3B protein expression was assessed by western blotting. d Quantitative analysis of p16INK4A detected by western blotting. Error bars indicate mean ± SD for three independent experiments. *P < 0.05, **P < 0.01, #P < 0.001. P value was calculated by one-way ANOVA test. (TIF 625 kb
