Abstract
Coronary artery disease (CAD) is a common and fatal cardiovascular disease. Among known CAD risk factors, miRNA polymorphisms, such as Has-miR-143 (rs41291957 C>G) and Has-miR-146a (rs2910164 G>A), have emerged as important genetic markers of CAD. Despite many genetic association studies in multiple populations, no study assessing the association between CAD risk and SNPs of miR-143 and miR-146 was documented in the Japanese people. Therefore, using the TaqMan SNP assay, we investigated two SNP genotypes in 151 subjects with forensic autopsy-proven CAD. After pathological observation, we used ImageJ software to assess the degree of coronary artery atresia. Moreover, the genotypes and miRNA content of the two groups of samples with atresia <10% and >10% were analyzed. The results showed that the CC genotype of rs2910164 was more frequent in patients with CAD than in controls, which was associated with the risk of CAD in the study population. However, Has-miR-143 rs41291957 genotype did not show a clear correlation with the risk of CAD.

Abstract
BACKGROUND miRNAs play a crucial role in the genesis of cancer, either as tumor suppressor genes or as oncogenes. Single Nucleotide Polymorphisms (SNPs) in the seed region of microRNAs (miRNAs) can dysregulate their levels in the tissues and thereby affect carcinogenesis. The association of SNP in miR-146a (rs2910164) with the risk of oral squamous cell carcinoma (OSCC) has not been understood. OBJECTIVE In the present study, we have determined the association and functional significance of miR-146a (rs2910164) SNP with susceptibility to OSCC predisposition. METHODS In the present case-control study, we enrolled 430 subjects from central India (215 OSCC cases and 215 healthy controls). We performed genotyping by Kompetitive Allele Specific PCR (KASP), and their correlation with OSCC susceptibility was analyzed. miRNA expression profiling in tumor tissues and adjacent normal tissues from six OSCC patients was done by a NanoString n-Counter-based assay. Subsequently, gene ontology and pathway analysis were performed with FunRich version 3.13. RESULTS The CC genotype of rs2910164 miR-146a was significantly associated with the increased risk for OSCC (CC vs GC, OR = 2.62; 95% CI: 1.48-4.66; p value = 0.001). However, the GC genotype was protective with GC vs CC (OR = 0.38, 95%CI =0.21-0.67, p-value = 0.001), and GC vs GG (OR = 0.58, 95%CI = 0.37-0.89, p-value = 0.01). CONCLUSION Our finding suggests that SNP rs2910164 of miR-146a may be a genetic risk factor for OSCC susceptibility in the Central India population. However, more extensive multicenter studies are required to validate these findings.

Abstract
According to 2020 global cancer statistics, digestive system tumors (DST) are ranked first in both incidence and mortality. This study systematically investigated the immunologic gene set (IGS) to discover effective diagnostic and prognostic biomarkers. Gene set variation (GSVA) analysis was used to calculate enrichment scores for 4,872 IGSs in patients with digestive system tumors. Using the machine learning algorithm XGBoost to build a classifier that distinguishes between normal samples and cancer samples, it shows high specificity and sensitivity on both the validation set and the overall dataset (area under the receptor operating characteristic curve [AUC]: validation set = 0.993, overall dataset = 0.999). IGS-based digestive system tumor subtypes (IGTS) were constructed using a consistent clustering approach. A risk prediction model was developed using the Least Absolute Shrinkage and Selection Operator (LASSO) method. DST is divided into three subtypes: subtype 1 has the best prognosis, subtype 3 is the second, and subtype 2 is the worst. The prognosis model constructed using nine gene sets can effectively predict prognosis. Prognostic models were significantly associated with tumor mutational burden (TMB), tumor immune microenvironment (TIME), immune checkpoints, and somatic mutations. A composite nomogram was constructed based on the risk score and the patient's clinical information, with a well-fitted calibration curve (AUC = 0.762). We further confirmed the reliability and validity of the diagnostic and prognostic models using other cohorts from the Gene Expression Omnibus database. We identified diagnostic and prognostic models based on IGS that provide a strong basis for early diagnosis and effective treatment of digestive system tumors.

Front Endocrinol (Lausanne) 2022; 13:961635. [PMID: 36237193 PMCID: PMC9551998 DOI: 10.3389/fendo.2022.961635] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/05/2022] [Accepted: 07/29/2022] [Indexed: 11/13/2022] Open
Abstract
OBJECTIVE Several studies have shown that miR-146a rs2910164 (C > G) is associated with type 2 diabetes mellitus (T2DM) susceptibility, but the results are still controversial. This study is divided into two parts, and one is to explore the relationship between miR-146a rs2910164 polymorphism and the genetic susceptibility of T2DM in Chinese Han population. Second, a meta-analysis on the basis of a larger sample size was used to determine whether this is a susceptibility gene for T2DM. METHODS A case-control study including 574 T2DM patients and 596 controls was used to evaluate the association of miR-146a rs2910164 polymorphism with the risk of T2DM in Chinese Han People. Then, we systematically searched studies investigating the correlation between miR-146a rs2910164 polymorphism and T2DM susceptibility published before April 2022 from PubMed, Web of Science, Wanfang, and China National Knowledge Infrastructure database, and a meta-analysis including six studies was carried out. The results were expressed by odds ratio (OR) and its 95% confidence interval (95% CI). RESULTS In a case-control study, we found that there were no statistical differences in genotype frequencies between T2DM and control group. Subgroup analysis showed that, compared with the CC genotype, CG + GG genotype was associated with a decreased risk of T2DM in the subgroup of individuals ≥ 65 years old (OR = 0.75; 95% CI: 0.58-0.98; P adjusted = 0.032) and BMI < 18.5 (OR = 0.16; 95% CI: 0.03-0.89; P adjusted = 0.037). In overall meta-analysis, significant heterogeneity was detected. No significant association between miR-146a rs2910164 polymorphism and T2DM was observed in all genetic models under random effects models. Subgroup analysis revealed that there was a significant difference in genotype frequencies between the T2DM and control group in recessive model (CC vs. CG + GG: OR = 1.79; 95% CI: 1.08-2.96; PQ = 0.307, I 2 = 4.0%) and homozygote model (CC vs. GG: OR = 1.79; 95% CI: 1.07-3.00; PQ = 0.216, I 2 = 34.7%) in Caucasians. CONCLUSION The results of our study demonstrate that the miR-146a rs2910164 polymorphism might have ethnicity-dependent effects in T2DM and may be related to T2DM susceptibility in Caucasians.

Abstract
The genetics of human longevity has long been studied, and in this regard, centenarians represent a very informative model. Centenarians are characterized by 2 main features: 1) the capability to avoid or postpone the major age-related diseases; and 2) a high level of heterogeneity of their phenotype. The first suggests that longevity and resistance to diseases are mediated by shared mechanisms, the latter that many strategies can be used to become long lived, likely as a result of variable genome-environment interactions. The authors suggest that the complexity of genome-environment interactions must be considered within an evolutionary and ecological perspective and that the concept of "risk allele" is highly context dependent, changing with age, time, and geography. Genes involved in both longevity and cardiovascular diseases, taken as a paradigmatic example of age-related diseases, as well as other emerging topics in genetics of longevity, such as micro-ribonucleic acid (miRNA) genetics, polygenic risk scores, environmental pollutants, and somatic mutations are discussed.

Abstract
The incidence of cancer and Alzheimer’s disease (AD) increases exponentially with age. A growing body of epidemiological evidence and molecular investigations inspired the hypothesis of an inverse relationship between these two pathologies. It has been proposed that the two diseases might utilize the same proteins and pathways that are, however, modulated differently and sometimes in opposite directions. Investigation of the common processes underlying these diseases may enhance the understanding of their pathogenesis and may also guide novel therapeutic strategies. Starting from a text-mining approach, our in silico study integrated the dispersed biological evidence by combining data mining, gene set enrichment, and protein-protein interaction (PPI) analyses while searching for common biological hallmarks linked to AD and cancer. We retrieved 138 genes (ALZCAN gene set), computed a significant number of enriched gene ontology clusters, and identified four PPI modules. The investigation confirmed the relevance of autophagy, ubiquitin proteasome system, and cell death as common biological hallmarks shared by cancer and AD. Then, from a closer investigation of the PPI modules and of the miRNAs enrichment data, several genes (SQSTM1, UCHL1, STUB1, BECN1, CDKN2A, TP53, EGFR, GSK3B, and HSPA9) and miRNAs (miR-146a-5p, MiR-34a-5p, miR-21-5p, miR-9-5p, and miR-16-5p) emerged as promising candidates. The integrative approach uncovered novel miRNA-gene networks (e.g., miR-146 and miR-34 regulating p62 and Beclin1 in autophagy) that might give new insights into the complex regulatory mechanisms of gene expression in AD and cancer.

Abstract
Purpose The miRNA-146a rs2910164 C>G polymorphism may contribute to the development of cancer. However, the association between this polymorphism and the risk of esophagogastric junction adenocarcinoma (EGJA) remains unclear. In the present study, we carried out a case–control study to explore the potential relationship between miRNA-146a rs2910164 C>G polymorphism and EGJA risk. Patients and methods In total, 1,063 EGJA patients and 1,677 cancer-free controls were enrolled. The SNPscan™ genotyping assay, a patented technology, was used to test the genotyping of miRNA-146a rs2910164 C>G polymorphism. Results We found that miRNA-146a rs2910164 C>G polymorphism was associated with a risk of developing EGJA (additive model: adjusted odds ratio (OR), 1.27; 95% CI, 1.07–1.51; P=0.006; homozygote model: adjusted OR, 1.31; 95% CI, 1.03–1.65; P=0.027 and dominant model: adjusted OR, 1.36; 95% CI, 1.15–1.60; P<0.001). After adjustment for the Bonferroni correction, these associations were also found in additive and dominant genetic models. In the subgroup analyses, after adjustment by sex, age, alcohol consumption, and smoking status, results of multiple logistic regression analysis indicated that miRNA-146a rs2910164 C>G polymorphism increased the risk of EGJA in males, females, <64 years old, ≥64 years old, never smoking, and never drinking subgroups. Conclusion The current study highlights that the miRNA-146a rs2910164 C>G polymorphism increased the risk of EGJA in eastern Chinese Han population.

Abstract
Three functional microRNA polymorphisms (miR-499 rs3746444 A > G, miR-196a rs11614913 C > T and miR-146a rs2910164 G > C) have been reported to be associated with breast cancer (BC) risk. However, the results of the published studies are inconsistent. In order to obtain a more credible result, we conducted this meta-analysis. We searched PubMed, EMBASE and Web of Science databases to identify relevant studies. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were used to assess the association. Thirty-eight eligible studies with 17,417 cases and 18,988 controls were included in this meta-analysis. Our results showed that the rs3746444 was associated with an increased breast cancer risk in the four genetic models (G vs. A: OR = 1.17, P = 0.008; GG vs. AA: OR = 1.41, P < 0.001; AG vs. AA: OR = 1.10, P = 0.036; GG+AG vs. AA: OR = 1.16, P = 0.001). In the subgroup analysis by ethnicity, significant correlation remained in Asians but not in Caucasians. For rs11614913, obvious decreased breast cancer risk was observed in Caucasian populations (T vs. C: OR = 0.93, P = 0.044). However, we couldn't detect an association between rs2910164 and breast cancer risk. This meta-analysis demonstrates that rs3746444 could increase breast cancer risk in Asians and in general populations, while rs11614913 could decrease the risk of breast cancer in Caucasians. The rs2910164 polymorphism has no association with breast cancer risk. More multicenter studies with larger sample sizes are required to verify our results.

Abstract
Background: Despite recent decrease in the incidence of gastric cancer, it is still a common type of cancer in the north of Iran. Many evaluations have shown that polymorphisms of cytokine genes like that for interleukin 6 (IL-6), which play important roles in regulation of the immune response, can increase the risk of gastric cancer. This study examined the role of the IL-6-174 gene polymorphism in susceptibility in an Iranian population. Method: Genomic DNA was extracted from peripheral whole blood of 100 patients and 361 healthy controls. Genotyping was accomplished by the sequence-specific primer-polymerase chain reaction (SSP-PCR) method and statistical analyses were carried out using Fisher’s exact test. Frequencies of the IL-6-174 G/C genotypes were determined under co-dominant, dominant, and recessive genetic models. Results: An association between the polymorphism of IL-6 -174 G/C and susceptibility to gastric cancer was observed. The frequency of G allele was higher in patients (78%) than in controls (70.5 %) (OR=1.48, 95% CI=1.01-2.20, P=0.04). Conclusions: The high G allele and G/G genotype frequency in patients compared to control subjects suggests that the IL-6 -174 G/C polymorphism may influence the susceptibility to gastric cancer. In addition, the demographic information showed that most of the subjects were male (69.0%) that gastric cancer is related to environmental factors.

Abstract
microRNAs (miRNAs) are nowadays recognized as an essential component of gene regulatory networks. Furthermore, deregulation of miRNAs expression often contributes to human pathologies. Recently, a substantial number of single nucleotide polymorphism (SNPs) and rare mutations within pri-, pre- and mature miRNA sequences have been reported. These miRNA SNPs have often been associated with human disease. However, due to the complexity of miRNA biogenesis and the genome-wide functional effects of miRNAs, the determination of biological consequences of these miRNA SNPs remains challenging. Despite an increasing number of reports linking miRNA SNPs with human pathologies, few reports have analyzed the mechanism by which miRNA-SNPs contribute to disease pathogenesis. In this review, we discuss how single polynucleotide polymorphisms in miRNAs genes may influence miRNAs expression and function and thus potentially alter disease pathogenesis.

Abstract
OBJECTIVE This study aimed to investigate the value of microRNA (miR) gene polymorphisms in evaluating the efficacy of transcatheter arterial chemoembolization (TACE) in primary hepatocellular carcinoma (HCC). MATERIALS AND METHODS A total of 507 patients with primary HCC were enrolled at our hospital from August 2010 to December 2014. All of them received TACE and were divided into either an effective treatment group (237 cases), or an ineffective group (270 cases) according to the treatment efficacy. Polymerase chain reaction-restriction fragment length polymorphism was used to genotype the single-nucleotide polymorphisms of miR-196a2 rs11614913, miR-146a rs2910164, miR-499a rs3746444, and miR-149 rs2292832, and the genotypes and allele frequencies between the two groups were compared. RESULTS The frequencies of the CC genotype of miR-196a2 (rs11614913) and the GG genotype of miR-499a (rs3746444) were significantly higher in the ineffective group than in the effective group (both p < 0.05). For miR-196a2 (rs11614913), the overall survival (OS) of patients with the TT genotype was higher than patients with the CT+CC genotypes (p < 0.05); for miR-499a (rs3746444), the OS of patients with the AA genotype was higher than patients with the AG+GG genotypes (p < 0.05). MiR-196a2 rs11614913, miR-499a rs3746444, hepatitis B surface antigen (HbsAg), hepatitis B history, and Child-Pugh classification were independent prognostic factors for OS (all p < 0.05). CONCLUSION MiR-196a2 rs11614913 and miR-499a rs3746444 were significantly associated with a curative effect and a positive prognosis of TACE for primary HCC.

Abstract
The accepted paradigm for intestinal-type gastric cancer pathogenesis is a multistep progression from chronic gastritis induced by Helicobacter pylori (H. pylori) to gastric atrophy, intestinal metaplasia, dysplasia and ultimately gastric cancer. The genetic and molecular mechanisms underlying disease progression are still not completely understood as only a fraction of colonized individuals ever develop neoplasia suggesting that bacterial, host and environmental factors are involved. MicroRNAs are noncoding RNAs that may influence H. pylori-related pathology through the regulation of the transcription and expression of various genes, playing an important role in inflammation, cell proliferation, apoptosis and differentiation. Indeed, H. pylori have been shown to modify microRNA expression in the gastric mucosa and microRNAs are involved in the immune host response to the bacteria and in the regulation of the inflammatory response. MicroRNAs have a key role in the regulation of inflammatory pathways and H. pylori may influence inflammation-mediated gastric carcinogenesis possibly through DNA methylation and epigenetic silencing of tumor suppressor microRNAs. Furthermore, microRNAs influenced by H. pylori also have been found to be involved in cell cycle regulation, apoptosis and epithelial-mesenchymal transition. Altogether, microRNAs seem to have an important role in the progression from gastritis to preneoplastic conditions and neoplastic lesions and since each microRNA can control the expression of hundreds to thousands of genes, knowledge of microRNAs target genes and their functions are of paramount importance. In this article we present a comprehensive review about the role of microRNAs in H. pylori gastric carcinogenesis, identifying the microRNAs downregulated and upregulated in the infection and clarifying their biological role in the link between immune host response, inflammation, DNA methylation and gastric carcinogenesis.

Abstract
Purpose Polymorphism in miR-146a (rs2910164) has been reported to be associated with gastric cancer risk in the Chinese population. We aimed at evaluating the relationship between rs2910164 and the clinical characteristics and outcomes in stage IB–III gastric cancer patients treated with adjuvant chemotherapy after surgery. Materials and methods Ninety-eight patients with stage IB–III gastric cancer treated with surgical resection followed by adjuvant chemotherapy of oxaliplatin and fluoropyrimidines were included in the analysis. Genomic DNA was extracted from peripheral blood sample of all patients. Polymerase chain reaction-based restriction fragment length polymorphism assay was used to determine the genotypes. Results The 2-year disease-free survival rate was 63%, and the 3-year overall survival (OS) rate was 73.4%. In dominant model, we found that rs2910164 GC + CC (G: guanine, C: cytosine) genotype carriers were less likely to develop lymph node metastasis (P=0.059). The 3-year OS was significantly different for patients with or without lymph node metastasis (89.3% vs 63.7%, P=0.015) and for patients with stage I–III disease (100.0%, 88.6%, and 56.9%; P=0.018). The 3-year OS for GC + CC carriers was significantly higher than for GG carriers (75.1% vs 66.7%, P=0.041). After the multivariant Cox regression analysis, histological grade (P=0.033, relative risk: 5.116, 95% confidence interval: 1.145–22.865) and lymph node status (P=0.031, relative risk: 6.648, 95% confidence interval: 1.191–37.118) were found to be independent prognostic factors for these patients. Conclusion rs2910164 could be associated with the lymph node metastasis and prognosis of Chinese gastric cancer patients treated with oxaliplatin and fluoropyrimidines after surgical resection.

Abstract
AIMS The present study is to investigate the effect of microRNA-146a (miR-146a) and ethnic factor in the occurrence of cervical cancer in Uygur women in Xinjiang Uygur Autonomous Region. METHODS A total of 620 pieces of cervical tissues were obtained between September 2010 and September 2013, including 208 cases of cervicitis, 207 cases of cervical intraepithelial neoplasia, and 205 cases of cervical cancer. The relative expression of miR-146a in tissues was measured using quantitative real-time polymerase chain reaction. Polymerase chain reaction - restriction fragment length polymorphism was used to determine the genotypes of miR-146a (rs2910164). Differences between two groups and multiple groups were compared using t-test and one-factor analysis of variance, respectively. Comparison of genotype compositions and genetic balance examinations were performed using χ(2) test. RESULTS Uygur women had earlier age of marriage, more times of pregnancy, and more childbirths than Han women. The miR-146a (rs2910164) genotype composition was significantly different between Uygur and Han, with the ratio of GG genotype in Uygur being higher than that in Han. Logistic regression analysis showed that miR-146a (rs2910164) genotypes were significantly correlated to ethnic factor and tumor sizes. The expression of miR-146a was elevated in cervical intraepithelial neoplasia and cervical cancer, especially for Uygur women, with the GG genotype being the most highly expressed. CONCLUSIONS The miR-146a (rs2910164) polymorphism is significantly correlated to ethnic factor and tumor diameters. miR-146a has differential expression in cervical tissues. Allele G of miR-146a (rs2910164) is related to the high expression of miR-146a, and the progression of cervical cancer.

Abstract
Gastric cancer has high morbidity and mortality in China. It is ranked first in malignant tumors of the digestive system. Its etiology and pathogenesis are still unclear, but they may be associated with a variety of factors. Genetic susceptibility genes have become a research hotspot in China. Elucidating the genetic mechanisms of gastric cancer can facilitate achieving individualized prevention and developing more effective methods to reduce clinical adverse consequences, which has important clinical significance. Genetic susceptibility results from the influence of genetic factors or specific genetic defects that endow an individual's offspring with certain physiological and metabolic features that are prone to certain diseases. Currently, studies on the genetic susceptibility genes of gastric cancer have become a hotspot. The purpose is to screen for the etiology of gastric cancer, search for gene therapy methods, and ultimately provide a scientific basis for the prevention and control of gastric cancer. This article reviews the current progress of studies on genetic susceptibility genes for gastric cancer.

Abstract
OBJECTIVE Previous studies have evaluated the association between miR-27a rs895819 polymorphism and cancer risk in Chinese population, but the results were inconclusive. The present meta-analysis was conducted to clarify these controversies. METHODS A comprehensive search was conducted to identify all relevant case-control studies of miR-27a rs895819 polymorphism and cancer risk in Chinese participants. We calculated odds ratios (ORs) with 95% confidence intervals (CIs) to assess the strength of any association. RESULTS A total of 12 case-control studies involving 2655 cases and 3106 controls were included. Overall, the results suggested that there was no significant association between miR-27a rs895819 polymorphism and cancer risk in Chinese population (OR = 1.14, 95%CI 0.86 to1.15, P = 0.85 for GG vs. AA). In the subgroup analysis by the source of controls, no significant association was found either among hospital-based group (OR = 1.16, 95%CI 0.78 to 1.73) or population-based group (OR = 1.06, 95%CI 0.74 to 1.35). However, when stratified by cancer types, we found a significant association between the polymorphism with colorectal cancer (OR = 1.56, 95%CI 1.01 to 2.40 for GG vs. AA). CONCLUSION miR-27a rs895819 polymorphism was associated with increased risk of colorectal cancer in Chinese population.
