Article Title: The m6A demethylase FTO promotes C/ EBPβ ‐ LIP translation to perform oncogenic functions in breast cancer cells

doi: 10.1111/febs.70033

Figure Lengend Snippet: FTO knockdown has a limited effect on mRNA translation. (A) Fold change in translation efficiency upon FTO knockdown in MDA‐MB‐231 cells is displayed, color coded by FDR. Significantly regulated genes above threshold are indicated by gene symbol. (B) RT‐qPCR analysis of DICER mRNA expression in MDA‐MB‐231 cells with FTO knockdown (shFTO1 or shFTO2) versus shRNA‐scrambled (scr) control. Significance was determined by one‐way ANOVA with Dunnett's post hoc test (mean ± SEM, n = 3 biological replicates). (C) Immunoblots showing no change in DICER protein expression upon knockdown of FTO (shFTO1 or shFTO2) in MDA‐MB‐231 versus scrambled control (SCR). β‐Actin was used as loading control. Quantification is shown on the right. Significance was determined by one‐way ANOVA with Dunnett's post hoc test (mean ± SEM, n = 3 biological replicates). (D) RT‐qPCR analysis of COL1A1 and SMAD6 mRNA expression in MDA‐MB‐231 upon FTO knockdown (shFTO1 or shFTO2) versus shRNA‐scrambled (scr) control. Significance was determined by one‐way ANOVA with Dunnett's post hoc test (mean ± SD, n = 3 biological replicates). (E) Immunoblot analysis of COL1A1, SMAD6, and DICER protein expression in MDA‐MB‐231 upon FTO knockdown (shFTO1 or shFTO2) versus shRNA‐scrambled (scr) control, and β‐Actin as loading control. 5 days and 20 days refer to days in cell culture after transduction with shRNA retroviral vector. (F) Subsequence abundance analysis of codons at the +15 position relative to the ribosome protected fragment (RPF) 5′‐end. All transcripts in the coding frame are considered for this analysis. No significant enrichment or depletion of codons can be seen, indicating no obvious shortages of amino acids causing ribosome stalls/halts.
