To evaluate the relationship between the aryl hydrocarbon receptor () rs2066853 gene polymorphism and the risk of male infertility. PubMed, Embase, Web of Science, and Chinese National Knowledge Infrastructure (CNKI) were searched for relevant case-control studies up to 31 July 2019. Odds ratio (OR) and 95% confidence interval (95% CI) were used to assess the strength of associations. Finally, seven case-control studies involving 1247 cases and 1762 controls were included in this meta-analysis. The pooled results showed that there was no significant association between rs2066853 gene polymorphism and male infertility risk (A vs. G: OR = 1.08, 95% CI = 0.83-1.39; AA vs. GG: OR = 1.16, 95% CI = 0.65-2.04; AA vs. GA + GG: OR = 1.17, 95% CI = 0.66-2.07; AA + GA vs. GG: OR = 0.99, 95% CI = 0.85-1.15). Subgroup analysis by ethnicity showed the same result. However, significant association was found between rs2066853 gene polymorphism and male infertility risk in oligoasthenotspermia (A vs. G: OR = 2.52, 95% CI = 1.72-3.70). In conclusion, our meta-analysis indicated that rs2066853 gene polymorphism might be associated with an increased susceptibility to oligoasthenotspermia.

Stroke is the second leading cause of death and a major contributor to disability worldwide, with the highest prevalence in developing countries. Ischemic stroke (IS) is a complex disease resulting from genetic and environmental interactions. The present work is a pilot study exploring the association of estrogen receptor-α (ESR1) and aryl hydrocarbon receptor (AHR) SNPs with IS in a small Egyptian population of IS patients.

Breast cancer is the most malignant tumor among women in the world. Single nucleotide polymorphisms (SNPs) might better predict breast cancer prognosis. PvuII (T/C substitution), XbaI (A/G substitution), and aryl hydrocarbon (AhR) (G/A substitution) were evaluated as possible genetic prognostic factors for breast cancer.

Article Synopsis
- The study investigates the relationship between specific genetic variations (polymorphisms) in aryl hydrocarbon receptor-nuclear translocator and repressor genes and the levels of cord blood IgE (CbIgE) in infants.
- A total of 206 infant-mother pairs with elevated CbIgE and 421 control pairs were analyzed through genotyping and statistical methods.
- Findings reveal that the rs2066853 genetic variant is significantly associated with higher CbIgE levels, especially when combined with high maternal total IgE levels, suggesting a genetic influence on CbIgE elevation in infants.

We conducted a research study to create the groundwork for personalized solutions within a skin aging segment. This test utilizes genetic and general laboratory data to predict individual susceptibility to weak skin characteristics, leveraging the research on genetic polymorphisms related to skin functional properties. A cross-sectional study was conducted in a collaboration between the Private Clinic Medicina Practica Laboratory (Vilnius, Lithuania) and the Public Institution Lithuanian University of Health Sciences (Kaunas, Lithuania).

Background: Host genetic characteristics and environmental factors interactions may play a crucial role in cervical carcinogenesis. We investigated the impact of functional genetic variants of four xenobiotic-metabolizing genes (AhR, CYP1A1, GSTM1, and GSTT1) on cervical cancer development in Tunisian women.
Methods: The AhR gene polymorphism was analyzed using the tetra-primer ARMS-PCR, whereas the CYP1A1 polymorphism genotypes were identified by PCR-RFLP.
