ABSTRACT
Adult T-cell leukemia (ATL) is an oncogenic disease derived from the HTLV-1-infected T cells and there is no effective therapy known yet. We previously reported that down-regulation of N-myc downstream-regulated
gene-2 (NDRG2) expression by DNA Methylation and genetic deletion presents one of the most common
alterations in adult T-cell leukemia (ATL) and other various kinds of cancers. A stress-induced NDRG2
suppresses important signaling pathways (PI3K and NF-κB) through the de-phosphorylation of PTEN and NIK
as a PP2A recruiter. In this manuscript, we identified protein arginine methyltransferase 5 (PRMT5) as a
NDRG2/PP2A binding partner. A NDRG2/PP2A complex down-regulated arginine methyltransferase activity of
PRMT5 through de-phosphorylation of the serine and threonine residues and changing its co-localization to the nucleus of ATL cell lines increasing the histone arginine methylation; however, PRMT5 was highly
phosphorylated and localized in cytoplasm in NDRG2-deficient ATL.
