RASSF8 downregulation promotes lymphangiogenesis and metastasis in esophageal squamous cell carcinoma

Lymphatic vessels are the major routes of human esophageal squamous cell carcinoma (ESCC) metastasis. Tumor cells secrete pro-lymphangiogenic factors to induce new lymphatic vessels, promoting lymph node metastasis. In this study, we show that RAS association domain family 8 (RASSF8) expression in E...

Sumario:Lymphatic vessels are the major routes of human esophageal squamous cell carcinoma (ESCC) metastasis. Tumor cells secrete pro-lymphangiogenic factors to induce new lymphatic vessels, promoting lymph node metastasis. In this study, we show that RAS association domain family 8 (RASSF8) expression in ESCC clinical samples was inversely correlated with lymph node metastasis and patients survival. Tumor cells with low RASSF8 expression had higher apparent migratory ability, and promoted and lymphangiogenesis both in vitro and in vivo. RASSF8 downregulation enhanced VEGF-C expression and caused subcellular redistribution of p65 in ESCC. Our results show that RASSF8 acts as a tumor suppressor in ESCC and is a potential therapeutic target for preventing lymph node metastasis.
