With this in mind, we extracted expression data of MALAT1, PTBP1, and PSF from The Cancer Genome Atlas (TCGA) and analyzed correlation of their expression levels for different types of human cancers, which include HCC, breast invasive carcinoma (BRCA), lung adenocarcinoma (LUAD), colon adenocarcinoma (COAD), and acute myeloid leukemia. This evidence concerns the gene PTBP1 and invasive breast carcinoma.
