Do high vascular endothelial growth factor levels in NZW mice correlate with collagen deposition in allergic asthma?
In allergic lung inflammation, the combination of EPO deficiency and overexpression of VEGF found in NZW mice is associated with less collagen deposition, less mucus and reduced tissue eosinophilia. Eosinophil activation and airway hyperreactivity in NZW mice were similar to the other strains.
The erlotinib/O-desmethyl-erlotinib metabolic ratio reflecting the individual metabolic activity of erlotinib correlated with the severity of skin rash and outcome in patients treated with EGFR tyrosine kinase inhibitors. The metabolic ratio determined in serum may be used for therapeutic monitoring in erlotinib treatment and decisions on individual dosing to rash in rash-negative patients.
