Yang et al. (2019) demonstrate lower tumor volume and percentage of Ki-67-stained HCCLM3 cells and less lung metastasis of HCCLM3 cells in an SNHG7 knockdown mice group compared with the control group. Additionally, Yao et al. (2019) show that the expression of the metastasis-associated protein matrix metalloproteinase-9 (MMP-9) is increased in SNHG7-overexpressing HepG2 implanted cells, suggesting a mechanism for enhancing the effect of SNHG7 on tumor metastasis. This evidence concerns the gene LYPD5 and neoplasm.
