NOP2 and colorectal carcinoma: In a previous study, we found that proliferation‐associated nucleolar protein p120 (NOP2), which is one of the highly conserved eukaryotic m5C methyltransferases, is significantly upregulated in colon cancer tissues and cells compared with that in the healthy controls, functioning as an oncogene that promotes proliferation, migration, and invasion of CRC cells [17].
