Abstract
Mesenchymal stem cells (MSCs) can be differentiated into cardiac, endothelial, and smooth muscle cells. Therefore, MSC-based therapeutic approaches have the potential to deal with the aftermaths of cardiac diseases. However, transplanted stem cells rarely survive in damaged myocardium, proposing that paracrine factors other than trans-differentiation may involve in heart regeneration. Apart from cytokines/growth factors, MSCs secret small, single-membrane organelles named exosomes. The MSC-secreted exosomes are enriched in lipids, proteins, nucleic acids, and microRNA (miRNA). There has been an increasing amount of data that confirmed that MSC-derived exosomes and their active molecule microRNA (miRNAs) regulate signaling pathways involved in heart repair/regeneration. In this review, we systematically present an overview of MSCs, their cardiac differentiation, and the role of MSC-derived exosomes and exosomal miRNAs in heart regeneration. In addition, biological functions regulated by MSC-derived exosomes and exosomal-derived miRNAs in the process of heart regeneration are reviewed.

Genetic polymorphism of the Dab2 gene and its association with Type 2 Diabetes Mellitus in the Chinese Uyghur population. PeerJ 2023; 11:e15536. [PMID: 37361044 PMCID: PMC10290452 DOI: 10.7717/peerj.15536] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2023] [Accepted: 05/19/2023] [Indexed: 06/28/2023] Open
Abstract
Objective The human Disabled-2 (Dab2) protein is an endocytic adaptor protein, which plays an essential role in endocytosis of transmembrane cargo, including low-density lipoprotein cholesterol (LDL-C). As a candidate gene for dyslipidemia, Dab2 is also involved in the development of type 2 diabetes mellitus(T2DM). The aim of this study was to investigate the effects of genetic variants of the Dab2 gene on the related risk of T2DM in the Uygur and Han populations of Xinjiang, China. Methods A total of 2,157 age- and sex-matched individuals (528 T2DM patients and 1,629 controls) were included in this case-control study. Four high frequency SNPs (rs1050903, rs2255280, rs2855512 and rs11959928) of the Dab2 gene were genotyped using an improved multiplex ligation detection reaction (iMLDR) genotyping assay, and the forecast value of the SNP for T2DM was assessed by statistical analysis of clinical data profiles and gene frequencies. Results We found that in the Uygur population studied, for both rs2255280 and rs2855512, there were significant differences in the distribution of genotypes (AA/CA/CC), and the recessive model (CC vs. CA + AA) between T2DM patients and the controls (P < 0.05). After adjusting for confounders, the recessive model (CC vs. CA + AA) of both rs2255280 and rs2855512 remained significantly associated with T2DM in this population (rs2255280: OR = 5.303, 95% CI [1.236 to -22.755], P = 0.025; rs2855512: OR = 4.892, 95% CI [1.136 to -21.013], P = 0.033). The genotypes (AA/CA/CC) and recessive models (CC vs. CA + AA) of rs2855512 and rs2255280 were also associated with the plasma glucose and HbA1c levels (all P < 0.05) in this population. There were no significant differences in genotypes, all genetic models, or allele frequencies between the T2DM and control group in the Han population group (all P > 0.05). Conclusions The present study suggests that the variation of the Dab2 gene loci rs2255280 and rs2855512 is related to the incidence of T2DM in the Uygur population, but not in the Han population. In this study, these variations in Dab2 were an independent predictor for T2DM in the Uygur population of Xinjiang, China.

The association of plasma levels of miR-146a, miR-27a, miR-34a, and miR-149 with coronary artery disease. Mol Biol Rep 2022; 49:3559-3567. [PMID: 35553331 DOI: 10.1007/s11033-022-07196-5] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2021] [Accepted: 01/27/2022] [Indexed: 10/18/2022]
Abstract
BACKGROUND Coronary artery disease (CAD) is considered to be one of the most pivotal causes of death in the world. Over the past two decades, significant changes occurred in the diagnosis, prognosis, and treatment of CAD, which has helped reduce mortality rates. microRNAs (miRs) are a class of more than 5000 non-encoding RNA molecules (21-25 nucleotides across the length) that regulate complex biological processes. Today, miRNAs are used to study cardiovascular diseases. In the present study, the expression of miR-146a،miR-27, miR-149, and miR-34a in plasma suffering from CAD and the control group were investigated. METHODS AND RESULTS The present research was performed on 30 men with CAD and 30 healthy men as controls. The expression levels of miR-146a, miR-27a, miR-149, and miR-34a in the plasma of patients with CAD and the control group were measured using real-time PCR. Also, the correlation between the expression of circulating miRs levels and biochemical LDL-C, HDL-C, BMI, and total cholesterol was evaluated. The expression of miR-27a in the plasma of the CAD group was higher than in the control group (p = 0.020). The expression of miR-146a was downregulated in CAD patients compared to normal subjects (p = 0. 026). However, the expression of miR-34a, miR-149 in the plasma of CAD patients was not significantly different with the control group. In addition to, a direct correlation was found between the expression of miR-146a and HDL-c, the expression of miR-27a and LDL-C and the expression of miR-34a and total cholesterol. Also, the negative correlation between expressions of miR-149 with BMI was reported. CONCLUSION The obtained results demonstrated that miRs were closely related to biochemical factors and it points out the fact that miRNAs can be applied as a potential strategy for diagnosis and treatment of CAD.

Abstract
Circular RNA (circRNA) is a class of non-coding RNA (ncRNA) that plays an important regulatory role in various biological processes of the organisms and has a major function in muscle growth and development. However, its molecular mechanisms of how it regulates pork quality remain unclear at present. In this study, we compared the longissimus dorsi (LD) muscle expression profiles of Queshan Black (QS) and Large White (LW) pigs to explore the role of circRNAs in meat quality using transcriptome sequencing. A total of 62 differentially expressed circRNAs (DECs), including 46 up- and 16 down-regulated, 39 differentially expressed miRNAs (DEmiRNAs), including 21 up- and 18 down-regulated and 404 differentially expressed mRNAs (DEMs), including 174 up- and 230 down-regulated were identified, and most circRNAs were composed of exons. Our results indicated that the DEC parent genes and DEMs were enriched in the positive regulation of fast-twitch skeletal muscle fiber contraction, relaxation of skeletal muscle, regulation of myoblast proliferation, AMPK signaling pathway, Wnt and Jak-STAT signaling pathway. Furthermore, circSETBP1/ssc-miR-149/PIK3CD and circGUCY2C/ssc-miR-425-3p/CFL1 were selected by constructing the competitive endogenous RNA (ceRNA) regulatory network, circSETBP1, circGUCY2C, PIK3CD and CFL1 had low expression level in QS, while ssc-miR-149 and ssc-miR-425-3p had higher expression level than LW, our analysis revealed that circSETBP1, circGUCY2C, ssc-miR-149, ssc-miR-425-3p, PIK3CD and CFL1 were associated with lipid regulation, cell proliferation and differentiation, so the two ceRNAs regulatory networks may play an important role in regulating intramuscular fat (IMF) deposition, thereby affecting pork quality. In conclusion, we described the gene regulation by the circRNA-miRNA-mRNA ceRNA networks by comparing QS and LW pigs LD muscle transcriptome, and the two new circRNA-associated ceRNA regulatory networks that could help to elucidate the formation mechanism of pork quality. The results provide a theoretical basis for further understanding the genetic mechanism of meat quality formation.

Single dose of synthetic microRNA-199a or microRNA-149 mimic does not improve cardiac function in a murine model of myocardial infarction. Mol Cell Biochem 2021; 476:4093-4106. [PMID: 34287784 DOI: 10.1007/s11010-021-04227-w] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2021] [Accepted: 07/14/2021] [Indexed: 10/20/2022]
Abstract
Intramyocardial injection of synthetic microRNAs (miRs) has recently been reported to be beneficial after myocardial infarction (MI). We conducted a randomized blinded study to evaluate the efficacy and reproducibility of this strategy in a mouse model of reperfused MI using rigorous methodology. Mice undergoing a 60-min coronary occlusion followed by reperfusion were randomly assigned to control miR, hsa-miR-199a-3p, hsa-miR-149-3p, or hsa-miR-149-5p mimic treatment. Intramyocardial injections of miRs were performed in the border zone right after reperfusion. At 8 weeks after MI, there were no significant differences in ejection fraction (EF) among groups (EF = 27.1 ± 0.4% in control group [n = 6] and 25.9 ± 0.5%, 26.0 ± 0.8%, and 26.6 ± 0.6% in hsa-miR-199a-3p, hsa-miR-149-3p, or hsa-miR-149-5p groups, respectively [n = 9 each]). Net change (delta) in EF at 8 weeks compared with day 3 after MI was - 4.1% in control and - 3.2%, - 2.4%, and - 0.4% in the miR-treated groups (P = NS). Assessment of cardiac function by hemodynamic studies (a method independent of echocardiography) confirmed that there was no difference in left ventricular systolic or diastolic function among groups. Consistent with the functional data, histological analysis showed no difference in scar size, cardiomyocyte area, capillary density, collagen content, or apoptosis among groups. In conclusion, this randomized, blinded study demonstrates that intramyocardial injection of a single dose of synthetic hsa-miR-199a-3p, hsa-miR-149-3p, or hsa-miR-149-5p mimic does not improve cardiac function or remodeling in a murine model of reperfused MI. The strategy of using synthetic miR mimics for cardiac repair after MI needs to be evaluated with rigorous preclinical studies before its potential clinical translation.

Abstract
Background Neuroblastoma (NB) is one of most common childhood tumors with high mortality among children worldwide. microRNAs (miRNAs) have been reported to play essential roles in the pathogenesis and therapeutics of NB. However, the role of miR-149 and its mechanism remain poorly understood. Main methods The expression levels of miR-149, cell division cycle 42 (CDC42) and B-cell lymphoma 2 (BCL2) were measured in NB tissues or cells by quantitative real-time polymerase chain reaction or western blot. Cell proliferation was measured by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) and colony formation assays. Cell apoptosis was detected by flow cytometry. Chemosensitivity of NB cells to doxorubicin (Dox) was analyzed by MTT assay. The interaction between miR-149 and CDC42 or BCL2 was explored by luciferase activity and RNA immunoprecipitation analyses. Results Our data indicated that low expression of miR-149 was displayed in NB tissues and cells and associated with poor survival rate. Overexpression of miR-149 inhibited cell proliferation and colony formation but promoted cell apoptosis and chemosensitivity to Dox in NB cells. Moreover, CDC42 and BCL2 were targeted by miR-149. Additionally, CDC42 and BCL2 mRNA levels were elevated in NB tissues and cells and restoration of CDC42 or BCL2 reversed the regulatory effect of miR-149 on NB progression. Conclusion Our data suggested that miR-149 suppressed cell proliferation and improved Dox chemosensitivity by regulating CDC42 and BCL2 in NB, providing a novel avenue for treatment of NB.
