They reported that after treating gastric cancer cells with 5-fluorouracil (5-Fu) and DDP, the level of the miRNA miR-877-3p increased, and the level of the suppressive protein SOCS2 decreased, which suggested that miR-877-3p can regulate the oncogenic functions of gastric cancer cells by suppressing the target gene SOCS2. The gene discussed is SOCS2; the disease is gastric cancer.
