KIAA1429/VIRMA promotes breast cancer progression by m⁶ A-dependent cytosolic HAS2 stabilization.

ABSTRACT: N⁶ -methyladenosine (m⁶ A), 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 m⁶ A is regulated by methyltransferases, demethylases, and m⁶ A-binding proteins that function in large part by regulating mRNA expression and function. Here, we investigate the expression of m⁶ A regulatory proteins in breast cancer. We find that expression of KIAA1429/VIRMA, a component of the m⁶ A 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,
