miR-503-5p Inhibits Colon Cancer Tumorigenesis, Angiogenesis, and Lymphangiogenesis by Directly Downregulating VEGF-A

Scientists observed considerable downregulation of miR-503-5p expression in colon cancer cells and tissues and significant correlation with the TNM stage, differentiation grade and lymph node metastasis of colon cancer. Overexpression of miR-503-5p promoted the apoptosis and G1 arrest of colon cancer cells, and inhibited migration, proliferation, invasion and colony formation.
