METTL3 regulates tumor process via Snail. a Western blotting analysis was applied to measure the protein expression level of E-cadherin, METTL3, SNAIL and Vimentin. GAPDH was used as a loading control. b Representative images and quantitative analysis of CRC cell migration based on wound healing assay. c Increased expression of SNAIL in sh-METTL3 CRC cell promoted CRC cell invasion ability based on transwell assay. d The colony formation ability of CRC cells overexpressing SNAIL or not was measured by colony formation assay in sh-METTL3 CRC cell. e EDU assay in CRC cells was performed the to measure the proliferation level. f CCK-8 assay was applied to measure the proliferation level of CRC cells after transfected with ov-SNAIL or not in sh-METTL3 CRC cell. g Flow cytometry analysis the proportion of apoptosis. *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001
