This method allows capture of CTC from patients' blood and subsequent release of viable CTC for downstream off-chip culture, analyses and characterization. Medicine Gene-environment Interaction Models to Unmask Susceptibility Mechanisms in Parkinson's Disease Vivian P. Chou1, Novie Ko1, Theodore R. Holman2, Amy B. Manning-Boğ1 1Center for Health Sciences, SRI International, 2Department of Chemistry and Biochemistry, University of California-Santa Cruz Lipoxygenase (LOX) isozymes can generate products that may increase or decrease neuroinflammation and neurodegeneration. A gene-environment interaction study could identify LOX isozyme-specific effects. Using the 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) model of nigrostriatal damage in two LOX isozyme-deficient transgenic lines allows for comparison of the contribution of LOX isozymes on dopaminergic integrity and inflammation.
