[10] found that H2 gas downregulated the expression of lncRNA MALAT1 and EZH2 while upregulating miR‐124‐3p in Human Gastric Cancer Cell Line MGC‐803 (MGC‐803), Human Gastric Cancer Cell Line BGC‐823 (BGC‐823) gastric cancer cell lines and gastric cancer mouse models, thereby significantly inhibiting tumor growth and reducing cancer cell proliferation and migration. The gene discussed is MALAT1; the disease is gastric cancer.
