NSUN2 and gastric cancer: The RNA cytosine-C(5)-methyltransferase (NSUN2) is found to be up-regulated in gastric cancer (GC), and the NR_033928, which acts as an up-regulated NSUN2 long non-coding RNA (lncRNA) to promote GLS expression by interacting with the IGF2BP3/HUR complex, is closely associated with the development of gastric cancer, the progression of the disease, and a poor patient prognosis [10].
