PRMT5-Mediated ALKBH5 Methylation Promotes Colorectal Cancer Immune Evasion via Increasing CD276 Expression by Sen Meng, Hao Liu, Jiayu Xu, Chuyin Deng, Xingyou Qian, Sufang Chu, Wei-Guo Zhu, Jiuling Zhu, Hongmei Yong, Zhongwei Li, Jin Bai

“…Here, we found that PRMT5 directly catalyzes AlkB homologue 5 (ALKBH5) symmetric dimethylation at the R316 residue (meR316-ALKBH5), which enhances TRIM28-mediated ALKBH5 ubiquitination degradation. Then, an ALKBH5 decrease attenuates ALKBH5-mediated m6A demethylation on the CD276 transcript 3′ untranslated region, which increases CD276 messenger RNA stability and its expression in CRC cells. …”
