Upregulation of PRMT1 is observed in many cancer types and often correlates with cancer grade and poor patient prognosis (14, 22, 23, 24, 25, 26, 27, 28), and there are a growing number of studies suggesting that PRMT1 is an important regulator in many pathways that are dysregulated in cancers (14, 26, 29, 30, 31, 32, 33, 34, 35, 36). Here, PRMT1 is linked to cancer.
