Review Meta Analysis
Association of endothelial nitric oxide synthase gene polymorphisms with end-stage renal disease: a systematic review and meta-analysis.
Endothelial nitric oxide synthase (eNOS) is one of the potent regulators of intra renal hemodynamics. Polymorphisms of eNOS gene may be involved in the progression of renal disease, and may be the causative factors that contribute to the deterioration of renal functions. During the past decades, several studies investigated the association of eNOS polymorphisms with the risk of end-stage renal disease (ESRD), but the results remain unclear and the mechanisms are not defined. Our study was designed to examine the role of different eNOS genetic polymorphisms in the progression of ESRD. ⋯ The evidence accumulated suggested that 4b/a and G894T polymorphisms in the eNOS gene were associated with ESRD susceptibility, indicating that 4a and T allele carriers might become significant genetic molecular markers for the onset of ESRD in overall populations. However, more studies should be performed in the further studies.
