KIAA1429/VIRMA promotes breast cancer progression by m6A-dependent cytosolic HAS2 stabilization

ABSTRACT: N6-methyladenosine (m6A), the most abundant internal modification in eukaryotic mRNA, plays important roles in many physiological and pathological processes, including the development and progression of cancer. RNA modification by m6A is regulated by methyltransferases, demethylases, and m6A-binding proteins that function in large part by regulating mRNA expression and function. Here, we investigate the expression of m6A regulatory proteins in breast cancer. We find that expression of KIAA1429/VIRMA, a component of the m6A methyltransferase complex, is upregulated in breast cancer tissue and correlates positively with poor survival. KIAA1429/VIRMA is mislocalized to the cytosol of breast cancer tissues and cell lines, and shRNA-mediated knockdown inhibits breast cancer cell proliferation,
