Background: Single-nucleotide polymorphisms (SNPs) in microRNAs (miRNA) have been shown to be related with susceptibility to several human cancers. We evaluated the associations of rs3746444 in pre-miRNA hsa-mir-499 with the risk of gastric cancer (GC) in the Chinese population.
Patients And Methods: The rs3746444 (A>G) SNPs were genotyped in 201 GC and 213 non-cancer subjects in a case-control study by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis.
Results: There was no significant overall difference in the genotype distributions of rs3746444 (A>G) SNPs between cases and controls. In the logistic regression analyses, no significantly increased risk of GC was found to be associated with variant genotypes.
Conclusion: The rs3746444 (A>G) SNP is not associated with susceptibility to GC in the Chinese population.

Background Growing knowledge supports the importance of microRNAs (miRNAs) in modulating the initiation and development of breast cancer (BC) and underlying mechanisms. BC is a significant public health in females worldwide, where it remains the leading cause of death among Saudi females. Here, we evaluate the susceptibility of the miRNA genetic variants to the risk of BC in Saudi females.

Type 2 diabetes mellitus (T2DM) is a common metabolic disorder that results from complex interactions of both environmental and genetic factors. Many single nucleotide polymorphisms (SNPs), including noncoding RNA genes, have been investigated for their association with susceptibility to T2DM and its complications, with little evidence available regarding Caucasians. The aim of the present study was to establish whether four miRNA SNPs (miR-27a rs895819 T>C, miR-146a rs2910164 G>C, miR-196a2 rs11614913 C>T, and miR-499a rs3746444 A>G) are correlated with susceptibility to T2DM and/or diabetic polyneuropathy (DPN) in a Romanian population.

miRNAs are vital molecules of gene expression. They are involved in the pathogenesis of various common diseases, including atherosclerosis, its risk factors, and its complications. A detailed characterization of the spectrum of functionally significant polymorphisms of miRNA genes in patients with advanced carotid atherosclerosis is an important research task.

Numerous studies have reported single nucleotide polymorphisms (SNPs) in microRNAs (miRNAs) associated with unexplained recurrent spontaneous abortion (URSA). The present study aimed to conduct an updated meta-analysis to confirm a pooled effect size of the association between miRNA SNPs and URSA. The relevant literature was searched on PubMed, EMBASE, Web of Science and Cochrane Library before July 2022 to identify case-control studies.

Background: Atherosclerosis remains a predominant cause of ischemic stroke (IS). Four miRNA polymorphisms associated with arteriosclerosis mechanism were meta-analyzed to explore whether they had predictive significance for IS.
Methods: PubMed, Excerpta Medica database, Web of Science, Cochrane Library, Scopus, China National Knowledge Infrastructure, and China Wanfang Database were searched for relevant case-control studies published before September 2022.
