Protein arginine methyltransferase 5 (PRMT5) is overexpressed in many cancer types and is a promising therapeutic target for several of them, including leukemia and lymphoma. However, we and others have reported that PRMT5 is essential for normal physiology. This dependence may become dose-limiting in a therapeutic setting, warranting the search for combinatorial approaches. Here we report that PRMT5 depletion or inhibition impairs homologous recombination (HR) DNA repair, leading to DNA damage accumulation, p53 activation, cell cycle arrest and cell death. PRMT5 symmetrically dimethylates histone and non-histone substrates, including several components of the RNA splicing machinery. We find that PRMT5 depletion or inhibition induces aberrant splicing of the multifunctional epigenetic and DNA repair factor TIP60/KAT5, which selectively affects its lysine acetyltransferase activity and leads to impaired HR. As HR-deficiency sensitizes cells to PARP inhibitors, we demonstrate here that PRMT5 and PARP inhibitors have synergistic effects on acute myeloid leukemia cells.
