Loxin polymorphism is associated with increased resistin levels and with oxidative status.

We hypothesized that LOX-1 polymorphism may impact on inflammation and cardiovascular risk by modulating systemic resistin expression.,276 men were randomly selected from a population-based cohort. Metabolic and inflammatory markers were evaluated at baseline and after 6-years follow-up, OLR1 (loxin) IVS4-14 A>G polymorphism was assessed.,Mean plasma resistin and nitrotyrosine values were significantly higher, and TAS was significantly lowered in homozygous for the G allele. The G allele was significantly and directly associated with resistin and nitrotyrosine values.,Enhanced oxidized-LDL uptake by LOX-1 G-allele carriers is associated with increased pro-oxidant status and resistin levels, suggesting a major uptake of ox-LDL by macrophages, smooth muscle cells, and monocytes.
