Microarray experiments showed that CF airway epithelial cells expressed several angiogenic factors such as VEGF-A, VEGF-C, bFGF, and PLGF at higher levels than control cells.
Before and during lung transplantation, VEGF-A serum concentrations were higher in CF versus COPD patients (P<0.05) and 60 min following reperfusion donor lungs transplanted to CF patients had higher tissue water contents than in COPD patients (P<0.05).
We administered: 1) Ad(GV)CFTR.10, a vector carrying the normal human CFTR cDNA (3 x 10(7) to 2 x 10(10) particle units (pu)) to airways of individuals with cystic fibrosis (CF); 2) Ad(GV)VEGF121.10, a vector carrying the normal human vascular endothelial growth factor (VEGF)121 cDNA, to the myocardium (4 x 10(8) to 4 x 10(10) pu) of individuals with coronary artery disease (CAD) and to lower extremity muscles (4 x 10(8) to 4 x 10(9.5) pu) of individuals with peripheral vascular disease (PVD); and 3) Ad(GV)CD.10, a vector carrying the Escherichia coli cytosine deaminase gene to skin (7 x 10(7) to 7 x 10(9) pu) and airways (7 x 10(8) to 7 x 10(10) pu) of normal individuals and to liver metastasis (4 x 10(8) to 4 x 10(9) pu) of individuals with colon carcinoma.
