Potential risk factors for hypospadias and negative correlation with DICER1 (rs3742330) A>G variant in Algerian population: A case-control study. Birth Defects Res 2024; 116:e2365. [PMID: 38801237 DOI: 10.1002/bdr2.2365] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2024] [Revised: 04/20/2024] [Accepted: 05/08/2024] [Indexed: 05/29/2024]
Abstract
BACKGROUND Hypospadias continues to be a prevalent congenital anomaly affecting the male external genitalia, characterized by an unclear origin and complex treatment approaches. This study aimed to investigate the risk factors associated with hypospadias and explore its genetic link with the DICER1 rs3742330 variant. METHODS The study involved two groups: 105 male children with hypospadias and 111 healthy male children as matched controls. Detailed history and physical examinations were conducted for all patients and controls. PCR-restriction fragment length polymorphism was utilized to identify the DICER1 rs3742330 variant, analyzing genotype distribution and allele frequency. Logistic regression analysis estimated the risk factors for hypospadias. RESULTS The mean age in the hypospadias group was 4.56 ± 2.50 years. The most prevalent type of hypospadias observed was the anterior type in 60 children (57.14%). Intrauterine growth restriction, advanced maternal age, and gestational hypertension were identified as significant risk factors for hypospadias (p = .011, p = .016, and p = .041, respectively). Regarding the genetic study, no significant difference was found in both genotype and allele frequencies of the DICER1 rs3742330 variant between case and control groups. CONCLUSIONS The rs3742330 variant in the DICER1 gene showed no association with hypospadias cases in the Algerian population. However, multivariate logistic regression analysis identified preterm birth, low birth weight, intrauterine growth restriction, advanced maternal age, gestational diabetes, and rural residence as the most significant independent predictors for hypospadias.

[PMID: 37759668 PMCID: PMC10526006 DOI: 10.3390/biology12091269] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/11/2023] [Revised: 09/11/2023] [Accepted: 09/18/2023] [Indexed: 09/29/2023]
Abstract
Multiple studies have reported new or exacerbated persistent or resistant hypertension in patients previously infected with COVID-19. We used literature-based discovery to identify and prioritize multi-scalar explanatory biology that relates resistant hypertension to COVID-19. Cross-domain text mining of 33+ million PubMed articles within a comprehensive knowledge graph was performed using SemNet 2.0. Unsupervised rank aggregation determined which concepts were most relevant utilizing the normalized HeteSim score. A series of simulations identified concepts directly related to COVID-19 and resistant hypertension or connected via one of three renin-angiotensin-aldosterone system hub nodes (mineralocorticoid receptor, epithelial sodium channel, angiotensin I receptor). The top-ranking concepts relating COVID-19 to resistant hypertension included: cGMP-dependent protein kinase II, MAP3K1, haspin, ral guanine nucleotide exchange factor, N-(3-Oxododecanoyl)-L-homoserine lactone, aspartic endopeptidases, metabotropic glutamate receptors, choline-phosphate cytidylyltransferase, protein tyrosine phosphatase, tat genes, MAP3K10, uridine kinase, dicer enzyme, CMD1B, USP17L2, FLNA, exportin 5, somatotropin releasing hormone, beta-melanocyte stimulating hormone, pegylated leptin, beta-lipoprotein, corticotropin, growth hormone-releasing peptide 2, pro-opiomelanocortin, alpha-melanocyte stimulating hormone, prolactin, thyroid hormone, poly-beta-hydroxybutyrate depolymerase, CR 1392, BCR-ABL fusion gene, high density lipoprotein sphingomyelin, pregnancy-associated murine protein 1, recQ4 helicase, immunoglobulin heavy chain variable domain, aglycotransferrin, host cell factor C1, ATP6V0D1, imipramine demethylase, TRIM40, H3C2 gene, COL1A1+COL1A2 gene, QARS gene, VPS54, TPM2, MPST, EXOSC2, ribosomal protein S10, TAP-144, gonadotropins, human gonadotropin releasing hormone 1, beta-lipotropin, octreotide, salmon calcitonin, des-n-octanoyl ghrelin, liraglutide, gastrins. Concepts were mapped to six physiological themes: altered endocrine function, 23.1%; inflammation or cytokine storm, 21.3%; lipid metabolism and atherosclerosis, 17.6%; sympathetic input to blood pressure regulation, 16.7%; altered entry of COVID-19 virus, 14.8%; and unknown, 6.5%.

Abstract
INTRODUCTION Venous thromboembolism (VTE) is the third most common hemostatic disease worldwide. Studies have reported a role for microRNA (miRNA) in the homeostasis and development of VTE. The ras-related nuclear protein (RAN) and exportin 5 (XPO5) genes are involved in miRNA biogenesis, as both regulate the transport of pre-miRNA from the nucleus to the cytoplasm. Therefore, the aim of the current study is to examine the association between RAN (rs14035) and XPO5 (rs11077) single nucleotide polymorphisms (SNPs) and VTE. METHODS The study sample consisted of 300 subjects (150 patients and 150 age and sex matched controls). The polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and tetra-primer amplification refractory mutation system (T-ARMS) techniques were used to genotype rs14035 and rs11077, respectively. RESULTS The results showed that there was a significant association between the XPO5 rs11077 and the risk of VTE (P < 0.05). Subjects with AC (OR: 2.08, CI:1.26-3.44) and CC (OR: 1.77, CI: 0.88-3.55) genotypes were at increased risk of the developing VTE. Regarding RAN gene, no association was found between rs14035 and VTE (P > 0.05). In addition, no associations were found between XPO5 rs11077 and RAN rs14035 genotypes with blood cell parameters (P > 0.05). As for the demographic characteristics, the results indicated a strong association between family history and body mass index (BMI) with the risk of VTE (P < 0.01). CONCLUSION The XPO5 rs11077, BMI and family history might contribute to the development of VTE in Jordan.

Single nucleotide variants in microRNA biosynthesis genes in Mexican individuals. Front Genet 2023; 14:1022912. [PMID: 36968598 PMCID: PMC10037310 DOI: 10.3389/fgene.2023.1022912] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2022] [Accepted: 01/02/2023] [Indexed: 03/08/2023] Open
Abstract
Background: MicroRNAs (miRNAs) are important regulators in a variety of biological processes, and their dysregulation is associated with multiple human diseases. Single nucleotide variants (SNVs) in genes involved in the processing of microRNAs may alter miRNA regulation and could present high allele heterogeneity in populations from different ethnic groups. Thus, the aim of this study was to genotype 15 SNVs in eight genes involved in the miRNA processing pathway in Mexican individuals and compare their frequencies across 21 populations from five continental groups.Methods: Genomic DNA was obtained from 399 healthy Mexican individuals. SNVs in AGO2 (rs2293939 and rs4961280), DGCR8 (rs720012), DICER (rs3742330 and rs13078), DROSHA (rs10719 and rs6877842), GEMIN3 (rs197388 and rs197414), GEMIN4 (rs7813, rs2740349, and rs4968104), TNRC6B (rs9611280), and XP05 (rs11077 and rs34324334) were genotyped using TaqMan probes. The minor allele frequency of each SNV was compared to those reported in the 1,000 Genomes database using chi-squared. Sankey plot was created in the SankeyMATIC package to visualize the frequency range of each variant in the different countries analyzed.Results: In Mexican individuals, all 15 SNVs were found in Hardy-Weinberg equilibrium, with frequencies ranging from 0.04 to 0.45. The SNVs rs4961280, rs2740349, rs34324334, and rs720012 in Mexican individuals had the highest minor allele frequencies worldwide, whereas the minor allele frequencies of rs197388, rs10719, rs197414, and rs1107 were among the lowest in Mexican individuals. The variants had high allele heterogeneity among the sub-continental populations, ranging from monomorphic, as was the case for rs9611280 and rs34324334 in African groups, to >0.50, which was the case for variants rs11077 and rs10719 in most of the populations. Importantly, the variants rs197388, rs720012, and rs197414 had FST values > 0.18, indicating a directional selective process. Finally, the SNVs rs13078 and rs10719 significantly correlated with both latitude and longitude.Conclusion: These data indicate the presence of high allelic heterogeneity in the worldwide distribution of the frequency of SNVs located in components of the miRNA processing pathway, which could modify the genetic susceptibility associated with human diseases in populations with different ancestry.

Abstract
Aim: SNPs in miRNA machinery genes may affect miRNA function by impacting their biogenesis. Here, we investigated the association between three SNPs in miRNA machinery genes (DICER rs1057035, DROSHA rs10719 and XPO5 rs11077) and bicuspid aortic valve (BAV). Materials & methods: Three polymorphisms were analyzed in 177 BAV patients and 414 healthy subjects by using a TaqMan®SNP assay. Results: The frequencies of XPO5 rs11077 genotype were significantly different between BAV patients and controls (p = 0.022). On multivariate logistic regression analysis, the XPO5 rs11077 C allele resulted a significant predictor of BAV (odds ratioadjusted = 0.65; CI: 0.42-0.98; p = 0.047). Conclusion: The XPO5 rs11077 SNP was associated with a decreased BAV risk supporting the causative role of miRNAs in aortic valve development.

Abstract
Background MicroRNA (miRNA) processing machinery gene variant was associated with several diseases. We aimed to explore for the first time the association of machinery gene (DROSHA rs10719A/G; DICER1 rs3742330A/G; RAN rs14035C/T; and XPO5 rs11077T/G) variants with the susceptibility and phenotype of end‐stage renal disease (ESRD). Method A total of 281 participants (98 ESRD patients and 183 healthy volunteers) were enrolled. Real‐Time TaqMan allelic discrimination assay was applied for the genotyping of the specified variants. Multiple logistic regression models, univariate, multivariate, and principal component analyses were carried out. Results Carrying one DICER1 rs3742330*G allele conferred protection against developing ESRD [heterozygote comparison: OR = 0.30, 95% CI = 0.15‐0.62, dominant model: OR = 0.35, 95% CI = 0.17‐0.70]. Similarly, for XPO5 rs11077T/G, homozygote and heterozygote carriers of G variant were less likely to develop ESRD [homozygote comparison: adjusted OR = 0.23, 95% CI = 0.11‐0.50, and heterozygote comparison: OR = 0.50, 95% CI = 0.22‐0.92, and allelic model: OR = 0.46, 95% CI = 0.34‐0.70]. RAN rs14035*TT subjects were 5 times more likely to develop ESRD while being heterozygote (CT) have twice the risk [homozygote comparison: 5.18, 95% CI = 2.28‐11.8, heterozygote comparison: OR = 2.12, 95% CI = 1.10‐409]. Subgroup analysis also detected DICER1 rs3742330*A, XPO5 rs11077*T, and RAN rs14035*T as genetic risk determinants for ESRD development in both sex and age categories. Two genotype combinations of DROSHA/DICER1/XPO5/RAN were associated with increased susceptibility to ESRD [A‐A‐T‐T: OR = 9.49, 95%CI = 2.48‐36.31 (P = .001) and G‐A‐T‐T: OR = 5.92, 95%CI = 1.77‐19.83 (P = .004), respectively]. Conclusion Variants and combined genotypes of DICER1 rs3742330, XPO5 rs11077, and RAN rs14035 might be associated with ESRD development in the study population. Integrating molecular analysis in ESRD risk stratification is warranted.

Abstract
Background Recurrent spontaneous abortion (RSA) is a serious problem in pregnancy. The exact etiology of RSA is unknown in more than 50% of all the patients. However, genetic variations are known as susceptibility factors for idiopathic RSA. Considering the role of miRNA biosynthesis machinery in the miRNA production and effect of miRNAs on various diseases, this study aimed to evaluate the effects of DICER1 rs3742330 and DROSHA rs6877842 polymorphisms on RSA risk. Methods In this case‐control study, 150 RSA patients and 195 age‐matched healthy female controls were recruited. Both polymorphisms were genotyped using PCR‐RFLP method. Results The frequency of DICER1 rs3742330AG genotype was higher in the control group (P = .022). There was a statistically significant association between rs3742330 polymorphism and a reduced RSA risk in dominant and allelic models (P = .013 and P = .007, respectively). No statistically significant association was found between DROSHA rs6877842 variant and RSA risk. The combination of AG and GC genotypes and G‐G alleles of DICER1 rs3742330 and DROSHA rs6877842 polymorphisms led to a decreased RSA risk. However, the synergic effect of rs3742330A and rs6877842G alleles (A‐G) and AA‐GG genotypes was associated with an increased RSA risk. Conclusion the DICER1 rs3742330AG genotype and combination of AG and GC genotypes and G‐G alleles of DICER1 rs3742330 and DROSHA rs6877842 polymorphisms were associated with a reduced RSA risk.

Association of Polymorphisms in miRNA Processing Genes With Type 2 Diabetes Mellitus and Its Vascular Complications in a Southern Chinese Population. Front Endocrinol (Lausanne) 2019; 10:461. [PMID: 31354628 PMCID: PMC6639830 DOI: 10.3389/fendo.2019.00461] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/26/2018] [Accepted: 06/25/2019] [Indexed: 01/12/2023] Open
Abstract
Objective: To evaluate the potential association between the genetic variants in miRNA processing genes (RAN, XPO5, DICER1, and TARBP2) and susceptibility to type 2 diabetes mellitus (T2DM) and its vascular complications, as well as to further investigate their interaction with environmental factors in type 2 diabetes. Methods: We conducted a case-control study in genotyping of five polymorphic loci, including RAN rs14035, XPO5 rs11077, DICER1 rs13078, DICER1 rs3742330, and TARBP2 rs784567, in miRNA processing genes to explore the risk factors for T2DM and diabetic vascular complications. Haplotype analyses, interactions of gene-gene and interactions of gene-environment were performed too. Results: We identified a 36% decreased risk of developing T2DM in individuals with the minor A allele in DICER1 rs13078 (OR: 0.64; 95%CI: 0.42-0.95; P: 0.026). The AA haplotype in DICER1 was also associated with a protective effect on T2DM compared with the AT haplotype (OR: 0.63; 95%CI: 0.42-0.94; P-value: 0.023). T2DM patients with the TT+TC genotype at RAN rs14035 had a 1.89-fold higher risk of developing macrovascular complications than patients with the CC genotype (OR: 1.89; 95%CI: 1.04-3.45; P-value: 0.037). We also identified two three-factor interaction models. One is a three-factor [DICER1 rs13078, body mass index (BMI), and triglyceride (TG)] interaction model for T2DM (OR: 5.93; 95%CI: 1.25-28.26; P = 0.025). Another three-factor [RAN rs14035, hypertension (HP), and duration of T2DM (DOD)] interaction model was found for macrovascular complications of T2DM (OR = 41.60, 95%CI = 11.75-147.35, P < 0.001). Conclusion: Our study provides new evidence that two single nucleotide polymorphisms (SNPs) of the miRNA processing genes, DICER1 and RAN, and their interactions with certain environmental factors might contribute to the risk of T2DM and its vascular complications in the southern Chinese population.
