Moreover, in breast tumors, angiogenesis marker VEGFA and lymphangiogenesis marker VEGFD expression was found to be significantly higher compared with non-adjacent control, and expression of miR526b and miR655 was positively correlated with VEGFA,VEGFC,VEGFD,CD31, and LYVE1 expression in breast tumour samples. The gene discussed is PECAM1; the disease is breast neoplasm.
