VEGFA and neoplasm: Despite the increased angiogenesis found in 231_HM.LNm5 primary tumours compared to the other three lines (Jin et al., 2012 and data not shown), average levels of the central hypoxia-induced pro-angiogenic factor VEGFA were unexpectedly lowest in 231_HM.LNm5 and the induction of VEGFA mRNA by hypoxia was blunted in 231_HM.LNm5 cells compared to 231_ATCC cells in vitro.
