Article Abstract

Genetics plays a role in the development of gestational diabetes mellitus (GDM), which poses serious risks to pregnant women and their children. Several studies have demonstrated a link between GDM susceptibility and rs13266634 C/T polymorphism in SLC30A8 gene and rs1111875 C/T and rs5015480 C/T, which are located near the linkage disequilibrium block containing the IDE, HHEX, and KIF11 genes. However, the results are conflicting. Therefore, we aimed to investigate the association between susceptibility to GDM and HHEX and SLC30A8 gene polymorphisms. PubMed, Web of Science, EBSCO, CNKI, Wanfang Data, VIP, and SCOPUS were used to search for research articles. The quality of the selected literature was evaluated using the Newcastle-Ottawa scale. A meta-analysis was performed using Stata 15.1. Allelic, dominant, recessive, homozygote, and heterozygote models were used for the analysis. Nine articles with 15 studies were included. (1) Four studies about HHEX rs1111875 showed that the C allele was associated with the susceptibility to GDM; (2) three studies on HHEX rs5015480 indicated that the C allele in rs5015480 was significantly associated with GDM; (3) eight studies about SLC30A8 rs13266634 showed that the C allele was significantly associated with the susceptibility to GDM; and (4) a subgroup analysis showed that the rs5015480 polymorphism in HHEX and rs13266634 polymorphism in SLC30A8 gene were associated with GDM susceptibility in Asians. The meta-analysis provided evidence that the C allele in rs1111875 and rs5015480 in HHEX and rs13266634 in SLC30A8 can increase the risk of GDM.PROSPERO registration number CRD42022342280.

Background: Single nucleotide polymorphisms (SNPs) in the solute carrier family 30 member 8 (SLC30A8) gene related to zinc metabolism have been associated with an impaired insulin metabolic response.

Objective: This study aimed to investigate variations in serum zinc concentration and insulin resistance biomarkers according to SNPs in the SLC30A8 gene among participants from the 2015 ISA-Nutrition.

Methods: A total of 497 participants were genotyped for SNPs rs13266634, rs3802177, and rs11558471.

Introduction: Genome-wide association study identified as a candidate gene for type 1 diabetes (T1D) in Caucasians. We aimed to investigate if rs229541 in conferred susceptibility to T1D in Chinese, independent of genotypes and if this gene polymorphism affected the clinical profiles of T1D.

Methods: In this case-control study, genotypes of rs229541 were obtained from 1278 patients with T1D and 1282 nondiabetic controls using MassARRAY.

Obesity, a global health issue, is associated with numerous diseases and has been shown to affect male reproductive health by inducing endocrine hormonal changes, chronic inflammation, oxidative stress and epigenetic alterations in reproductive cells. This study investigates the impact of obesity on testicular gene expression across mice, monkeys and humans, identifying 730 conserved testis-specific genes. High-fat diet-induced obesity upregulates GNG5, INHA, MSH5, SLC30A8 and SLC7A4 in testes, suggesting their potential as regulatory targets in testicular damage associated with obesity.

: Older adults are particularly susceptible to type 2 diabetes mellitus (T2DM) due to factors such as age-related insulin resistance, decreased physical activity, and deficiency of micronutrients, especially zinc. Studies have suggested that the risk allele of the zinc transporter 8 gene (SLC30A8) single-nucleotide poly-morphism (SNP) rs13266634 may contribute to T2DM susceptibility in addition to the complex protein interactions and alterations in the protein expressions and modifications associated with T2DM. This study was implemented to study the associations between SLC30A8 polymorphism, serum zinc levels, and the profiles of proteins differentially expressed in nondiabetic ( = 116) and prediabetic/diabetic ( = 149) subjects.
