found that PTBP1 regulates the development of inflammation-driven cancers by controlling exon 7 skipping of EXOC7 (58, 59).Xie reported that PTBP1 promotes bladder cancer proliferation and metastasis by modulating the alternative mRNA splicing of MEIS2-L and PKM2 (57). Here, PTBP1 is linked to urinary bladder carcinoma.
