Additional file 3: Figure S3. of MicroRNA-330-3p promotes cell invasion and metastasis in non-small cell lung cancer through GRIA3 by activating MAPK/ERK signaling pathway

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)
