Abstract
Background Although numerous case-control studies have examined the role of nitric oxide, particularly the 894G>T polymorphism in the eNOS gene, in increasing the risk of stroke and cancer, there remains a need for a comprehensive meta-analysis to clarify these associations. This study aims to address this gap by thoroughly evaluating the relationship between the eNOS 894G>T polymorphism and the risks of cancer and stroke. Methods We conducted an exhaustive search across digital databases including Science Direct, PubMed, and Google Scholar for studies published between 2012-2023. A rigorous selection process was employed to include relevant studies, which were then analyzed using robust meta-analytical techniques to determine the association between the eNOS 894G>T polymorphism and the risks of cancer and stroke. Results In this meta-analysis, we combined data from 2,013 cases and 2,187 control subjects for cancer risk assessment and 1,006 cases with 1,146 control subjects for stroke risk evaluation. Our findings indicate that the eNOS 894G>T polymorphism is significantly associated with an increased risk of cancer when comparing GG vs. GT+TT genotypes. Additionally, there is a notable correlation between this polymorphism and stroke incidence under various genetic models (T vs. G, TT vs. GG + GT, GG + GT vs. TT). Conclusions The results of this meta-analysis suggest a significant association between the eNOS 894G>T polymorphism and increased risks of cancer and stroke. These findings underscore the importance of conducting future studies with larger sample sizes and more comprehensive analyses further to elucidate the role of nitric oxide in these diseases. This study addresses some concerns but further detailed and non-repetitive research is necessary for conclusive evidence.
