VEGFA and neoplasm: In cell lines from breast (MCF-7), thyroid (FTC-133), and lung (A549) cancers, microgravity-induced changes include decreased cell adhesion and altered gene expression, particularly in molecules like E-cadherin (important for cell adhesion and tumor invasion suppression), vascular endothelial growth factor (VEGF, which promotes angiogenesis), and vimentin (a protein associated with epithelial–mesenchymal transition and cell migration), thereby affecting tumor proliferation and dissemination [15,16].
