Noncoding RNA Res 2022; 7:142-149. [PMID: 35756164 PMCID: PMC9192690 DOI: 10.1016/j.ncrna.2022.05.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2021] [Revised: 05/21/2022] [Accepted: 05/22/2022] [Indexed: 11/28/2022] Open
Abstract
This study aimed to investigate the genetic polymorphisms of miR-146a SNPs (rs2910164, rs57095329, and rs2431697) in systemic lupus erythematosus (SLE) patients and their association with clinical manifestations. The implication of SNPs on miR-146a expression level was also evaluated. SLE patients (113) and healthy controls (104) were registered in this study. The miR-146a SNPs were genotyped by polymerase chain reaction/restriction fragment length polymorphism (PCR-RFLP). Quantitative real-time PCR was used to measure the miR-146a expression in peripheral blood mononuclear cells (PBMCs). Our results showed that the genotype frequency of miR-146a SNPs didn't deviate significantly from the Hardy–Weinberg equilibrium (HWE). The AG genotype and G allele of miR-146a (rs57095329 A/G) might be considered a risk factor for the disease (OR = 2.27; CI: 0.78–6.57 and OR: 2.35; CI: 0.79–6.92 for AG genotype and G allele, respectively). Although, no statistical significance in the distribution of miR-146a SNPs (rs2910164, rs57095329, and rs2431697) was found, indicating the lack of association between the three SNPs and SLE susceptibility. Significantly, the higher frequency of the AA genotype of miR-146a (rs57095329) was associated with pancytopenia (P < 0.05), while the CT genotype of miR-146a (rs2431697) was associated (P < 0.05) with the antiphospholipid syndrome (APS). SLE patients had significantly higher levels of miR-146a compared to controls (P < 0.05). Elevation of miR-146a was independent of any SNP genotypes. In conclusion, this pilot study shows no association between miR-146a SNPs in our population group and susceptibility to lupus. Studies concerning other miRNAs in larger sample sizes are essential for a better understanding of their role in susceptibility to SLE disease. This study is concerned with genetic polymorphisms of miR-146a in Lupus patients. The AG genotype and G allele of miR-146a (rs57095329 A/G) might be considered a risk factor. No significance in the distribution of miR-146a SNPs (rs2910164, rs57095329, and rs2431697). miR-146a level was significantly elevated in SLE irrespective to any SNP genotypes. AA genotype of rs57095329 was associated with pancytopenia while the CT genotype of rs2431697 was associated with the APS.

Abstract
Diabetic nephropathy (DN) is the most common complication of diabetic patients, and has become a global healthcare problem. In this study, we used diabetic mice to evaluate the effect of Losartan on diabetic nephropathy, in which the experimental animals were divided into three groups: non-diabetic mice (db/m group), untreated-diabetic mice (db/db group), and Losartan-treated diabetic mice (db/db-losartan). Next, immunohistochemistry and immunofluorescence were used to detect WT-1 and synaptopodin expression, respectively. Protein levels of WT-1, synaptopodin, claudin1, and Pax-2 were assessed by Western blotting and real-time PCR. The miR-193a mRNA levels were quantitated by real-time PCR. The results showed that albuminuria was increased in diabetic mice compared with control animals and was significantly ameliorated by treatment with Losartan. In addition, Losartan significantly upregulated the immunopositive cell numbers of WT-1, the expression of WT-1 and synaptopodin in renal tissue. By contrast, expression of claudin1 and Pax-2 in renal tissue were decreased in db/db-losartan group. Besides, expression of miR-193a was decreased significantly in db/db-losartan group compared to the untreated diabetic group. Thus, Losartan has renoprotective effects on the control of tissue damage possibly by inhibiting the expression of miR-193a, thereby promoting the repair of podocyte injury in mice with diabetic nephropathy.

Abstract
BACKGROUND Diabetic nephropathy is one of the most common microvascular complications in patients with diabetes. MicroRNA (miRNA, miR) is closely related to the formation, development and pathophysiology of diabetic nephropathy. We aimed to investigate whether miR-193a-3p could be used as a potential biomarker for the diagnosis of diabetic nephropathy. METHODS Plasma samples were collected from all the participants. TaqMan Low Density Array analysis was employed to obtain the miRNA profiles of plasma samples, and qRT-PCR was used to confirm the result. Receiver operating characteristic curves were employed to evaluate the specificity and sensitivity of miR-193a-3p for predicting diabetic nephropathy. RESULTS The expression of miR-193a-3p and miR-320c was elevated and miR-27a-3p was decreased in diabetic nephropathy patients compared to patients with type 2 diabetes and healthy controls. We found that, in diabetic nephropathy patients, the elevated miR-193a-3p expression had a negative correlation with the level of evaluate glomerular filtration rate, while a positive correlation with the level of proteinuria. We further demonstrated that miR-193a-3p could be employed to distinguish patients with diabetic nephropathy. The Kaplan-Meier analysis showed that the high expression of miR-193a-3p significantly shortened the dialysis-free survival of diabetic nephropathy patients. CONCLUSION In conclusion, miR-193a-3p is involved in diabetic nephropathy pathogenesis and may serve as a potentially novel diagnostic biomarker for diabetic nephropathy.

Abstract
AbstractCooperative regulation among multiple microRNAs (miRNAs) is a complex type of posttranscriptional regulation in human; however, the global view of the system-level regulatory principles across cancers is still unclear. Here, we investigated miRNA-miRNA cooperative regulatory landscape across 18 cancer types and summarized the regulatory principles of miRNAs. The miRNA-miRNA cooperative pan-cancer network exhibited a scale-free and modular architecture. Cancer types with similar tissue origins had high similarity in cooperative network structure and expression of cooperative miRNA pairs. In addition, cooperative miRNAs showed divergent properties, including higher expression, greater expression variation and a stronger regulatory strength towards targets and were likely to regulate cancer hallmark-related functions. We found a marked rewiring of miRNA-miRNA cooperation between various cancers and revealed conserved and rewired network miRNA hubs. We further identified the common hubs, cancer-specific hubs and other hubs, which tend to target known anticancer drug targets. Finally, miRNA cooperative modules were found to be associated with patient survival in several cancer types. Our study highlights the potential of pan-cancer miRNA-miRNA cooperative regulation as a novel paradigm that may aid in the discovery of tumorigenesis mechanisms and development of anticancer drugs.
