Article Abstract
MicroRNA-499 (miR-499) rs3746444 polymorphism has been associated with the risk of coronary heart disease (CHD). However, results from several studies are inconsistent. This meta-analysis aimed to further investigate the possible association between miR-499 rs3746444 polymorphism and CHD risk. A total of 9 case-control studies included 5063 CHD cases and 4603 healthy subjects. The A allele at rs374644 was associated with significantly decreased CHD risk in the total population according to the allelic model (OR = 0.80, 95% CI = 0.68-0.93, P = 0.005), homozygous model (OR = 0.52, 95% CI = 0.39-0.71, P < 0.001) and heterozygous model (OR = 0.57, 95% CI = 0.43-0.77, P < 0.001). A similar trend was found specifically in Asian and Chinese populations. In contrast, the wild-type GG genotype at rs374644 was associated with significantly increased CHD risk in the total population, according to the dominant model (OR = 1.83, 95% CI = 1.39-2.42, P < 0.001), and a similar trend was found in Asian and Chinese populations. These results indicate that in the total population, as well as in Asian and Chinese populations, the wild-type GG genotype at rs374644 may be related to increased susceptibility to CHD, while the A allele may be protective against CHD.

Prevalence and genetic etiology of poly-cystic ovarian syndrome (PCOS) in Mauritania.
Front Reprod Health

Biomarker Research Unit for Mauritanian Populations, Faculty of Science and Technology, Nouakchott University, Nouakchott, Mauritania.
Background: Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder characterized by polycystic ovaries, oligoanovulation, hyperandrogenism and infertility. The exact specific causes of this disease have not yet been identified, but there is evidence of significant genetic involvement.
Objective: The present study aimed to evaluate the prevalence of PCOS and explore its gene polymorphisms in the Mauritanian population.

Introduction: MicroRNA (miRNA) single nucleotide polymorphisms (miRNA-SNPs) have been associated with pediatric acute lymphoblastic leukemia (ALL). However, since the results of these individual studies have been inconsistent, we performed a meta-analysis to help establish a statistical significance for the association between miRNA-SNPs and pediatric ALL risk. We also analyzed whether they confer susceptibility across country-specific studies by using different genetic models.

Article Synopsis
- This study aimed to understand the relationship between Traditional Chinese Medicine syndromes and the progression of gastric diseases related to H. pylori infection by merging TCM concepts with modern molecular biology and histopathology methods.
- It involved 203 participants, identifying key microRNA expressions (miR-499 and miR-149) and their link to various gastric conditions, revealing that miR-149 C allele is associated with lower gastric atrophy risk, while miR-499 levels correlate with higher cancer risk.
- The findings suggest that H. pylori infection exacerbates the progression of gastric lesions, particularly in patients with specific TCM syndromes, indicating a need for targeted treatment approaches in these populations.
Association between Mir-499, Mir-27a, and Mir-146a polymorphisms and their susceptibility to recurrent spontaneous abortion; analysis.

Objective: Recurrent spontaneous abortion (RSA) is defined as two or more pregnancy losses before 24 gestational weeks, accounting for 1-3% of fertile couples. A vast majority of single-nucleotide polymorphisms (SNPs) in some () genes can change the miRNA-mRNA interaction and are associated with the risk of RSA. This study was designed to better elucidate the association between miR-27a, miR-499, and miR-146a polymorphisms and RSA risk.

Introduction: Lung carcinoma is characterized by uncontrollable division of respiratory system cells with detrimental and lethal consequences on human health. Critical roles of microRNAs (miR) are scientifically approved in biological and pathological pathways, such as the role of miR-499 (rs3746444) in lung carcinomas. Thus, in this case-control investigation, we aimed to assess the probable relationship between miR-499C/T variant and the occurrence of lung carcinoma in Iranian population for the first time.
