Other studies on gastric cancer found that snoRA42, snoRA74A, and snoRD10 may play a potential role in the causation of gastric cancer 54, while ACA47, E2, ACA10, SNORA58, HBII-316, U70, U8, and U66, SNORA21 were identified as potential prognostic indicators of gastric cancer, as elevated levels of these snoRNAs were often associated with shorter survival time 55, 56. This evidence concerns the gene SNORA21 and gastric cancer.
