VEGFA and gastric cancer: However, we also found that transfection with the MYH9 overexpression plasmid failed to upregulate vascular endothelial growth factor A (VEGFA; Figure S17D) and that the level of MYH9 mRNA was not associated with that of Jun mRNA (Figure S18), which support gastric cancer cell heterogeneity and suggest that VEGFA and Jun expression may be regulated by multiple factors in cell lines and GC tissues.
