SNHG15 and neoplasm: SNHG15 was firstly recognized as a novel prognostic factor in GC patients.63, 64 Chen et al tested the expression level of SNHG15 in 106 pairs GC tissue and matched adjacent non‐tumour tissues using qRT‐PCR assay.40 The results showed that SNHG15 expression levels were higher in GC tissues than in the corresponding non‐cancerous tissues, and there was a close correlation between SNHG15 expression and clinical‐pathological factors in GC patients.
