In gastric cancer, SNHG6 was significantly highly expressed in gastric cancer tissues and in serum.70, 71 Yan K et al suggested that high expression of SNHG6 was related to the tumor grade and lymph node metastasis, which predicted a poor prognosis for patients.70 Yan et al and Li et al both proposed that SNHG6 existed not only in the cytoplasm but also in the nucleus, and the proportion in the cytoplasm was nearly 67.5%‐80%. This evidence concerns the gene SNHG6 and gastric cancer.
