Aberrant alternative splicing and epigenetic changes are both associated with
various cancers, but epigenetic regulation of alternative splicing in cancer is
largely unknown. Here we report that the intragenic DNA methylation-mediated
binding of Brother of Regulator of Imprinted Sites (BORIS) at the alternative
exon of Pyruvate Kinase (PKM) is associated with cancer-specific splicing that
promotes the Warburg effect and breast cancer progression. Interestingly, the
inhibition of DNA methylation, BORIS depletion, or CRISPR/Cas9-mediated deletion
of the BORIS binding site leads to a splicing switch from cancer-specific PKM2 to
normal PKM1 isoform. This results in the reversal of the Warburg effect and the
inhibition of breast cancer cell growth, which may serve as a useful approach to
inhibit the growth of breast cancer cells. Importantly, our results show that in
addition to PKM splicing, BORIS also regulates the alternative splicing of
several genes in a DNA methylation-dependent manner. Our findings highlight the
role of intragenic DNA methylation and DNA binding protein BORIS in
cancer-specific splicing and its role in tumorigenesis.
