The lines of evidence of in vitro studies have demonstrated that fucoidan inhibits the growth of non-small cell bronchopulmonary carcinoma NSCLCN6 cells [22] and human lymphoma HS-Sultan cells [23] and also induces apoptosis in cells derived from human lymphoma [23], promyelocytic leukemia [24], colon carcinoma [7], breast carcinoma [16], ovarian carcinoma, and hepatoma [25], including the prevention of angiogenesis by suppressing expression and secretion of the angiogenesis factor, vascular endothelial growth factor (VEGF) [26]. The gene discussed is VEGFA; the disease is lymphoma.
