It accelerates breast cancer progression by regulating exon 3 splicing of PTPMT1 (a phosphatase), altering the function of PTPMT1 and then activating the AKT/C-MYC signaling pathway, which promotes breast cancer cell proliferation and migration, and inhibits apoptosis (Du et al., 2021). Here, PTPMT1 is linked to breast carcinoma.
