Understanding the Impact of the Sirtuin 1 (SIRT1) Gene on Age-related Macular Degeneration: A Comprehensive Study.

Age-related macular degeneration (AMD) is a prevalent and incurable condition affecting the central retina and posing a significant risk to vision, particularly in individuals over the age of 60. As the global population ages, the prevalence of AMD is expected to rise, leading to substantial socioeconomic impacts and increased healthcare costs. The disease manifests primarily in two forms, neovascular and non-neovascular, with genetic, environmental and lifestyle factors playing a pivotal role in disease susceptibility and progression. This review article involved conducting an extensive search across various databases, including Google Scholar, PubMed, Web of Science, ScienceDirect, Scopus and EMBASE, to compile relevant case-control studies and literature reviews from online published articles extracted using search terms related to the work. SIRT1, a key member of the sirtuin family, influences cellular processes such as ageing, metabolism, DNA repair and stress response. Its dysregulation is linked to retinal ageing and ocular conditions like AMD. This review discusses the role of SIRT1 in AMD pathology, its association with genetic variants and its potential as a biomarker, paving the way for targeted interventions and personalised treatment strategies. In addition, it highlights the findings of case-control studies investigating the relationship between SIRT1 gene polymorphisms and AMD risk. These studies collectively revealed a significant association between certain SIRT1 gene variants and AMD risk. Further studies with larger sample sizes are required to validate these findings. As the prevalence of AMD grows, understanding the role of SIRT1 and other biomarkers becomes increasingly vital for improving diagnosis, treatment and, ultimately, patient outcomes.

Systemic assessment of solute carrier family 11-member A1 (rs17235409) gene polymorphism and Mycobacterium Tuberculosis Risk in Asian and caucasian population: A comprehensive updated meta-analysis.

Background: The present meta-analysis was assessed to confirm the association between solute carrier family 11-member A1 (SLC11A1) gene (rs17235409) polymorphism with the Mycobacterium tuberculosis infection in the Asian and Caucasian populations. Methods: A search was conducted using the databases including Google Scholar, Science Direct, Embase, and PubMed to find the case-control studies related to SLC11A1 gene polymorphism and tuberculosis (TB) infection. The MetaGenyo programme was used to perform statistical analyses of the data. The odds ratio and 95% confidence interval were calculated based on genetic models such as allelic model, dominant model, recessive model, and overdominant. The heterogeneity and publication bias for the present study were examined to assess its quality. The study was registered in PROSPERO (ID Number: 461434). Results: This current study revealed the association between the SLC11A1 gene polymorphism with TB. The statistical value obtained at P < 0.05 was deemed to be statistically significant. The meta-analysis results revealed that allele contrast and recessive models are significant association between SLC11A1 gene polymorphism with risk of TB infections, and dominant and overdominant models have no significant association with TB risk. In addition, the subgroup analysis based on the ethnicity dominant revealed a significant association with the risk of TB. Therefore, this results that the gene SLC11A1 has a significant association for allelic and recessive and has no significant association for dominant and overdominant with the risk of TB. Conclusion: According to the data retrieved from the database with respect to the present study revealed that SLC11A1 gene polymorphism rs17235409 for allelic, recessive models have been associated with TB infections, but dominant and overdominant models have not been associated with TB infections.
