Research on Slug's role in peritoneal metastatic cancer shows that ARL4C promotes gastric cancer peritoneal metastasis by activating Slug 32; CEACAM6 enhances EMT and Slug expression via the PI3K/AKT signaling pathway to promote gastric cancer peritoneal metastasis 33; and miR-203 targets the ERK1/2/Slug/E-cadherin signaling pathway to inhibit gastric cancer peritoneal metastasis 34. The gene discussed is ARL4C; the disease is gastric cancer.
