BRD9 and colonic neoplasm: In Figure 1, we utilised The Cancer Genome Atlas (TCGA) database to conduct an inaugural pan‐cancer analysis of BRD9, encompassing but not limited to gene expression, protein expression, survival status, mutation, protein phosphorylation, DNA methylation, N6‐methyladenosine (m6A) modification, gene set enrichment analysis, immune correlation analysis, etc. We followed up the bioinformatics analysis with experimental validation, employing tissue microarrays from lung and colon cancer patients to detect the expression of BRD9.
