RNA methyltransferase METTL14 and demethylase ALKBH5 promote growth and invasion of breast cancer cells. Clonogenic assay on scrambled-siRNA– or METTL14-siRNA (METTL14 KD)–transfected (A) or ALKBH5-siRNA (ALKBH5 KD)–transfected (C) MDA-MB-231 cells. Bar graphs below show the number of colonies counted microscopically in 10 different fields. (B and D) Photomicrograph showing migrated (top) and invaded (bottom) MDA-MB-231 cells in scrambled (Scr) or METTL14 KD (B) or ALKBH5 KD (D) cells. Bar graphs show the number of migrated and invaded cells. The data shown are means ± SEM for at least three independent experiments. **P < 0.01; ***P < 0.001; ****P < versus control group, t test. (E and F) Photomicrographs showing representative tumor growth in nude mice injected with 2 × 106 scrambled-siRNA–transfected (control), METTL14-siRNA (METTL14 KD)–transfected (A), or ALKBH5-siRNA (ALKBH5 KD)–transfected (B) MDA-MB-231 cells mixed with Matrigel. Bar graphs show mean tumor volume for the control (n = 8), METTL14 KD (n = 8), and ALKBH5 KD (n = 8) groups at the end of the study on day 21 after implantation of the cells.
