Between them: VEGFA, whose secretion is increased after radiotherapy under hypoxic environment and can also induce lymphangiogenesis [151]; fibroblast growth factor 2 (FGF2) and platelet-derived growth factor beta (PDGFβ), which are induced in the tumor microenvironment after fractionated radiation in murine tumors and also have a lymphangiogenic role [152,153]. The gene discussed is VEGFA; the disease is neoplasm.
