Abstract
BACKGROUND Neonatal necrotizing enterocolitis (NEC) is a common gastrointestinal emergency in neonates. MiRNA-192-5p was found associated with ulcerative colitis (UC) progression, also with aberrant expression in intestinal cancer tissue. However, the effects of miRNA-192-5p on NEC have not been reported. METHODS Based on the bioinformatics analysis of the GEO dataset, miR-192-5p was identified as the differentially expressed miRNA in NEC, and activated leukocyte cell adhesion molecule (ALCAM) was predicted as its target. After that, in vitro, rat intestinal epithelial cell-6 (IEC-6) were stimulated with LPS to construct a cell model of NEC. IEC-6 cells were transfected with miRNA-192-5p mimics, miRNA-192-5p inhibitors, or miRNA-192-5p inhibitors + sh-ALCAM, and relevant negative control. In vivo, SD rats were treated with artificial feeding, hypoxic reoxygenation, cold stimulation, and LPS gavage to induce NEC, followed by injection of agomiR-NC or agomiRNA-192-5p. Then effects of miRNA-192-5p on NEC model IEC-6 cell viability, apoptosis, ALCAM expression, Interleukin (IL)-1β and IL-6 levels, intestinal injury, intestinal permeability were detected. RESULTS MiRNA-192-5p expression was downregulated in NEC IEC-6 cells, whose overexpression increased IEC-6 cell viability. MiRNA-192-5p inhibitors increased IL-1β, IL-6 levels and promoted IEC-6 cell apoptosis. MiRNA-192-5p targeting of ALCAM decreased ALCAM expression, IL-1β, and IL-6 levels. AgomiRNA-192-5p decreased ALCAM, IL-1β, and IL-6 levels in intestinal tissue and pathological damage and increased miRNA-192-5p levels. CONCLUSION MiR-192-5p protects against intestinal injury by inhibiting ALCAM-mediated inflammation and intestinal epithelial cells, which would provide a new idea for NEC treatment.

Deficiency of miR-409-3p improves myocardial neovascularization and function through modulation of DNAJB9/p38 MAPK signaling. MOLECULAR THERAPY. NUCLEIC ACIDS 2023; 32:995-1009.

Abstract
Angiogenesis is critical for tissue repair following myocardial infarction (MI), which is exacerbated under insulin resistance or diabetes. MicroRNAs are regulators of angiogenesis. We examined the metabolic regulation of miR-409-3p in post-infarct angiogenesis. miR-409-3p was increased in patients with acute coronary syndrome (ACS) and in a mouse model of acute MI. In endothelial cells (ECs), miR-409-3p was induced by palmitate, while vascular endothelial growth factor (VEGF) and fibroblast growth factor (FGF) decreased its expression. Overexpression of miR-409-3p decreased EC proliferation and migration in the presence of palmitate, whereas inhibition had the opposite effects. RNA sequencing (RNA-seq) profiling in ECs identified DNAJ homolog subfamily B member 9 (DNAJB9) as a target of miR-409-3p. Overexpression of miR-409-3p decreased DNAJB9 mRNA and protein expression by 47% and 31% respectively, while enriching DNAJB9 mRNA by 1.9-fold after Argonaute2 microribonucleoprotein immunoprecipitation. These effects were mediated through p38 mitogen-activated protein kinase (MAPK). Ischemia-reperfusion (I/R) injury in EC-specific miR-409-3p knockout (KO) mice (miR-409ECKO) fed a high-fat, high-sucrose diet increased isolectin B4 (53.3%), CD31 (56%), and DNAJB9 (41.5%). The left ventricular ejection fraction (EF) was improved by 28%, and the infarct area was decreased by 33.8% in miR-409ECKO compared with control mice. These findings support an important role of miR-409-3p in the angiogenic EC response to myocardial ischemia.

Novel insights into the angiogenic function of JMJD2B in diabetic hind limb ischemia: involvement of activating Wnt/β-catenin pathway. Hum Cell 2023; 36:1011-1023. [PMID: 36773117 DOI: 10.1007/s13577-023-00874-x] [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: 10/18/2022] [Accepted: 02/01/2023] [Indexed: 02/12/2023]
Abstract
Critical limb ischemia (CLI) is a major health problem, in which diabetes is a risk factor. Lysine Demethylase 4B (JMJD2B) is a histone demethylase. Diabetic CLI model was established in mice by streptozotocin injection and femoral artery ligation. Reduced expression of JMJD2B in lower limb muscles was observed in CLI mice with or without diabetes, accompanied by impaired blood perfusion and mobility. Adenovirus-mediated JMJD2B overexpression improved blood perfusion and angiogenesis as indicated by the alternation in CD31, α-SMA, and VEGFA expression in the lower limb of diabetic mice with CLI. In vitro, JMJD2B expression and the proliferation and tube formation ability were inhibited by high glucose and ischemic conditions in HMEC-1 cells. Overexpressed-JMJD2B contributed to angiogenesis by promoting cell proliferation, migration, and tube formation of HMEC-1 cells, as well as increasing VEGFA and SDF-1 expression. Mechanism study indicated that JMJD2B overexpression activated the Wnt/β-catenin pathway by promoting β-catenin nuclear translocation and the expression. This might lead to stimulated angiogenesis, as demonstrated by the Wnt/β-catenin inhibitor XAV-939. Overall, our study revealed that JMJD2B was down-regulated in CLI mice with diabetes and JMJD2B overexpression promoted angiogenesis probably via the activation of Wnt/β-catenin pathway.

J Diabetes Investig 2021; 12:165-175. [PMID: 32579760 PMCID: PMC7858142 DOI: 10.1111/jdi.13334] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/02/2020] [Revised: 06/13/2020] [Accepted: 06/18/2020] [Indexed: 12/25/2022] Open
Abstract
AIMS/INTRODUCTION Microribonucleic acid-155 (microRNA155) and microRNA29 are reported to inhibit glucose metabolism in some cell and animal models, but no evidence from susceptible populations that examines the relationship between microRNA155 or microRNA29 and type 2 diabetes mellitus currently exists. Furthermore, target genes regulated by microRNA155 and microRNA29 that affect glucose and lipid metabolism remain unknown. MATERIALS AND METHODS Human participants were divided into normal weight (n = 72), obesity (n = 120) and type 2 diabetes (n = 59) groups. The contents of microRNA155 and microRNA29 abundance in serum were measured, and candidate genes potentially related to glucose and lipid metabolism targeted by either microRNA155 or microRNA29 were screened. Overexpression of microRNA155 and microRNA29 in HepG2 cells was used to verify candidate gene expression, and measure the effects on glucose and lipid metabolism. RESULTS Serum levels of microRNA155 and microRNA29 show a significant increase in individuals with obesity and type 2 diabetes compared with normal weight individuals. Identified target genes for microRNA155 were MAPK14, MAP3K10, DUSP14 and PRKAR2B. Identified target genes for microRNA29 were PEX11A and FADS1. Overexpression of microRNA155 or microRNA29 in HepG2 cells was found to downregulate the expression of identified target genes, and result in inhibition of triglyceride synthesis and glucose incorporation. CONCLUSIONS MicroRNA155 and microRNA29 were significantly higher in type 2 diabetes patients compared with the control patients, their levels were also positively correlated with fasting plasma glucose levels, and over-expression of microRNA155 or microRNA29 were found to downregulate glucose and lipid metabolism target genes, and reduce lipid synthesis and glucose incorporation in HepG2 cells.

Abstract
The ingestion of excessive free fatty acid could induce lipotoxicity in tissues and then lead to the initiation of many metabolism diseases. In this work, the protective effect of apigenin on palmitate-induced lipotoxicity in human aortic endothelial cells (HAEC) was investigated. Compared with 150 μM palmitate treatment alone, pretreatment with 10 μM apigenin for 6 h significantly increased the cell viability from 71.55 ± 3.62 to 91.06 ± 4.30% and improved mitochondrial membrane potential to the normal level (101.62 ± 11.72% of control). In addition, the production of nitric oxide was markedly elevated by apigenin cotreatment from 7.10 ± 3.95 to 94.20 ± 21.86%. The data-independent acquisition-based proteomic approach was used to study the protective mechanism, and the results revealed that 242 proteins were differently expressed in cells treated with palmitate and 93 proteins were reversed after apigenin supplementation. Apigenin realized its protective function mainly via regulating pathways such as IL-17, TNF, Fox O, cell adhesion, and endoplasmic reticulum protein processing. Collectively, these data demonstrated that apigenin supplement may serve as an alternative nutritional intervention to protect HAEC against lipotoxicity.
