In one study, Giatromanolaki et al. investigated coexpression of MUC1 glycoprotein with Multiple angiogenic factors such as vascular endothelial growth factor (VEGF), VEGF-receptor, basic fibroblast growth factor (bFGF), and bFGF-receptor (FGFR-2) in non-small cell lung cancer. This evidence concerns the gene VEGFA and non-small cell lung carcinoma.
