Does vCAM-1 increase levels of HGF in eosinophilic chronic rhinosinusitis cell culture?
VCAM-1 induced an increase in levels of HGF in the ECRS cell cultures. The rising transcriptional activity was demonstrated by means of RT-PCR. The levels of HGF were within physiological ranges, suggesting that a misbalance between HGF and VCAM-1 resulted in the establishment of ECRS. Further experiments are necessary to reveal the role of HGF in the development of ECRS. This is the first report about the effect of VCAM-1 on growth factors in ECRS cell culture.
Cholesterol feeding in C57BL6 mice results in alterations in the VEGF receptor-ligand family that may initially serve to limit the degree of vascular injury but these adaptations fail with the continuation of cholesterol feeding.
