METTL3 enhances translation rate in thymic carcinoma cells. A Puromycin incorporation for the indicated time points, detected by western blot analysis in control (siC) and METTL3-silenced (siMETTL3) TC1889 cells after 72 h. See also Additional file 3: Fig. S3 for quantifications (n = 4). B Representative ribosomal fractionation profiles of control (siC, blue) and 48 h METTL3-silenced (siMETTL3, red) TC1889 cells. On the right, calculation of area under the polysome and 80S curve after 48 h of METTL3 depletion, using ImageJ software (n = 3). C, D Western blot analysis showing the phosphorylated (C) and basal (D) levels of the indicated translation-related proteins in control (siC) and METTL3-silenced (siMETTL3) TC1889 cells after 72 h. Quantifications of three independent experiments are shown in the right panels. *p ≤ 0.05; **p ≤ 0.005; ***p ≤ 0.0005; ****p ≤ 0.00005; p values have been calculated by two-tailed T-test
