HNRNPA1 and cancer: The results obtained from the MethylScan and AlphaLISA studies from the in vitro culture of human cancer cells and healthy human PBMCs suggested that hnRNP-A1 could be utilized as a clinical biomarker of type I PRMT activity in human blood; therefore, modulation of arginine methylation on hnRNP-A1 by the type I PRMT inhibitor was further characterized.
