Cell Tissue Bank 2023; 24:125-137. [PMID: 35792987 DOI: 10.1007/s10561-022-10021-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2022] [Accepted: 06/14/2022] [Indexed: 11/29/2022]
Abstract
BACKGROUND Cardiac fibrosis characterized with the aberrant proliferation of cardiac fibroblasts and extracellular matrix (ECM) deposition is a major pathophysiological feature of atrial fibrillation (AF). Liraglutide has exerted an alleviative role in various cardiovascular diseases, and can also regulate the level of microRNAs (miRNAs). It has been reported that miR-21 modulated cardiac fibrosis in AF. However, the regulative effect of liraglutide on atrial fibrosis via miR-21 and the underlying mechanism are still unclear. METHODS The atrial fibroblasts were isolated from the heart of C57BL/6 mice, and treated with Angiotensin II (AngII) and liraglutide. The proliferation, migration, and ECM deposition were determined by cell counting Kit-8 (CCK-8), Brdu, transwell assay, cell scratch, reverse transcription-quantitative polymerase chain reaction (RT-qPCR), western blot and immunofluorescence. The underlying mechanism was explored after transfection of miR-21 mimics into cells. RESULTS Liraglutide inhibited proliferation, migration, invasion of fibroblast cell and ECM deposition in AngII-stimulated cardiac fibroblasts. Additionally, liraglutide decreased the AngII-induced increase in the expression level of miR-21, but enhanced the expression of phosphatase and tensin homolog (PTEN), a target of miR-21, thereby suppressing the phosphoinositide 3-kinase (PI3K)/AKT signaling pathway. Rescue assay confirmed that overexpression of miR-21 counteracted the ameliorative effect of liraglutide on the proliferation, migration, invasion and ECM deposition in fibroblasts stimulated by AngII. CONCLUSIONS Liraglutide dampened AngII-induced proliferation and migration, and ECM deposition of cardiac fibroblast via modulating miR-21/PTEN/PI3K pathway.

The miRNA-144-5p/IRS1/AKT axis regulates the migration, proliferation, and mineralization of osteoblasts: A mechanism of bone repair in diabetic osteoporosis. Cell Biol Int 2022; 46:2220-2231. [PMID: 36168858 DOI: 10.1002/cbin.11913] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2022] [Revised: 08/03/2022] [Accepted: 09/05/2022] [Indexed: 11/08/2022]
Abstract
Diabetic osteoporosis (DOP) is a disorder of bone metabolism induced by multiple mechanisms. Previous studies have revealed that microRNAs (miRNAs) play crucial roles in bone metabolism. MiRNA-144-5p has been proven to participate in the regulation of osteoblast activities; however, its specific mechanism in DOP has not been elucidated. This study investigated whether high glucose (HG) inhibited osteoblasts by regulating miRNA-144-5p. Our results showed that HG inhibited bone formation not only in vivo but also in vitro. We observed that HG severely hindered the migration, proliferation and mineralization of osteoblasts, while miRNA-144-5p was upregulated by way of the cell counting kit-8 assay, wound healing assay, alkaline phosphatase (ALP) activity assay and alizarin red staining. Double luciferase reporter experiments showed that miRNA-144-5p directly targeted insulin receptor substrate 1 (IRS1). The IRS1/AKT signaling pathway is closely related to osteoblasts' migration, proliferation, and mineralization. Silencing miRNA-144-5p promoted the mRNA, and protein expression of IRS1, thereby letting the expression of total AKT down, and then preventing phosphorylation of AKT into the nucleus to regulate migration, proliferation, and mineralization genes of osteoblasts. In conclusion, this study indicated that HG regulated the migration, proliferation, and mineralization of osteoblasts via the miRNA-144-5p/IRS1/AKT axis, which suggested a possible mechanism for DOP pathology.

Abstract
Diabetic cardiomyopathy (DCM) is the primary cause of morbidity and mortality in diabetic cardiovascular complications, which initially manifests as cardiac hypertrophy, myocardial fibrosis, dysfunctional remodeling, and diastolic dysfunction, followed by systolic dysfunction, and eventually end with acute heart failure. Molecular mechanisms underlying these pathological changes in diabetic hearts are complicated and multifactorial, including but not limited to insulin resistance, oxidative stress, lipotoxicity, cardiomyocytes apoptosis or autophagy, inflammatory response, and myocardial metabolic dysfunction. With the development of molecular biology technology, accumulating evidence illustrates that members of the class O of Forkhead box (FoxO) transcription factors are vital for maintaining cardiomyocyte metabolism and cell survival, and the functions of the FoxO family proteins can be modulated by a wide variety of post-translational modifications including phosphorylation, acetylation, ubiquitination, arginine methylation, and O-glycosylation. In this review, we highlight and summarize the most recent advances in two members of the FoxO family (predominately FoxO1 and FoxO3a) that are abundantly expressed in cardiac tissue and whose levels of gene and protein expressions change as DCM progresses, with the goal of providing valuable insights into the pathogenesis of diabetic cardiovascular complications and discussing their therapeutic potential and possible effects of salvianolic acids, a natural product.

Guo Q, Han C, Xu Y, Chen Q, Han X, Zhao S, Li J, Lu H. Tandem mass tag-based proteomic profiling revealed potential therapeutic targets and mechanisms of liraglutide for the treatment of impaired glucose tolerance. Front Endocrinol (Lausanne) 2022; 13:1031019. [PMID: 36452319 PMCID: PMC9701722 DOI: 10.3389/fendo.2022.1031019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/29/2022] [Accepted: 10/25/2022] [Indexed: 11/15/2022] Open
Abstract
OBJECTIVE Based on the tandem mass tag (TMT) technique, our study investigated the potential therapeutic targets of Liraglutide (LIRA) on streptozotocin (STZ) induced impaired glucose tolerance (IGT) in rats and discuss the biological mechanism of the drug against IGT. METHODS 10 rats were randomly selected from 31 male wistar rats of specific pathogen free (SPF) grade as control group and fed with conventional chow, offered the remaining rats a high fat and high sugar (HFSD) diet combined with an intraperitoneal injection of STZ to establish the IGT model, and excluded 2 non-model rats. Specifically, the model rats were randomly divided into Model group (n=10) and LIRA group (n=9). In addition, the LIRA group was subcutaneously injected with 0.06 mg/kg LIRA, during which the metabolic parameters including body weight and fasting blood glucose were recorded. After 8 weeks, samples were taken under anesthesia. Then, the cell morphology was observed using HE staining, and immunofluorescence was performed on the pancreatic tissues of the three groups of rats. Besides, the expression of differential proteins in pancreatic tissues of the three groups of rats was determined by the TMT proteomic labeling. Subsequently, Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) biological function analysis were performed on the intersection of Model and LIRA differential proteins. RESULTS LIRA could not only significantly reduce blood glucose levels but also improve islet cell morphology and function in IGT rats. Among the differential proteins between the model group and the blank group, 44 were reversed after LIRA treatment, of which 14 were up-regulated, while 30 were down-regulated, including PPIF, MPRIP, CYP51, TXNL1, BCL-2, etc. (FC>1.1 or<0.909, P<0.05). According to the GO and KEGG analysis results, it was related to biological processes such as fatty acid metabolism and adipocyte generation, which involved multiple signaling pathways regulating the function of islet cells, such as MAPK, PI, Ras, FcγR, and unsaturated fatty acids, and pyruvate metabolism. CONCLUSION To sum up, LIRA participated in anti-IGT therapy through regulation of multiple target proteins and biological functions. This study is of great reference for further exploring the mechanism of action of LIRA at the protein level of IGT.
