MiRNA expression profiling and identification of a miRNA regulator for muscle regeneration in the ischemic limb with proanthocyanidins treatment of adult mice

ABSTRACT: Using the highly sensitive miRNA array, we screened 411 differentially expressed genes microRNAs in the ischemic muscle with proanthocyanidins treatment and we explored the functions of these miRNAs in the ischemic muslce by Gene Ontology and Kyoto Encyclopedia of Genes annotation. The enrichment results indicated that these miRNAs mainly participated in the muscle regeneration process. Furthermore, the quantitative real-time polymerase chain reaction, immunohistochemistry and dual luciferase reporter assay results showed that miR-133b-3p is a specific regulator of MKP1/ p38-MAPK signal axis, offering a novel therapeutic opportunity for limb ischemic injury.

Transcriptome analysis of Streptococcus mutans biofilms in response to cranberry proanthocyanidins

Project description:The influence of cranberry proanthocyanidins on the transcriptomic responses of Streptococcus mutans during biofilm formation was investigated. Treatment regimens simulating topical exposures experienced clinically (twice-daily, 60 s each) were used over saliva-coated hydroxyapatite biofilm model. Cranberry proanthocyanidins (1.5 mg/ml) in 15% ethanol was used to treat the biofilms. Four biological replicates each for the treatment and vehicle control were used for RNA extraction and microarray.

Real-time quantitative PCR analysis of murine non-ischemic and ischemic wound edge

Project description:Wound edges from a murine bipedicle flap ischemic wound model were collected 3 days post wounding. RNA from ischemic and non-ischemic wound edges was isolated by miRVana RNA isolation kit. Mature miRNAs were then profiled by real-time PCR.

Grape Proanthocyanidins Modulate MicroRNA Expression in Human pancreatic cancer cells

Project description:Mi(cro)RNAs are small non-coding RNAs of 18-25 nucleotides in length that modulate gene expression at the posttranscriptional level. Grape seed proanthocyanidins (GSPs), a biologically active component of grape seeds, have been shown to have positive effects on anti-cancer. In current study, to explore whether GSPs can regulate miRNA expression and possible molecular mechanisms involved in anti-cancer, we prepared the pancreatic cancer (PC) cells samples (SS3, SS12 and SS24) at 3, 12 and 24h after GSPs treatments respectively; and control samples (SC3, SC12 and SC24) were also collected accordingly. miRNA-seq transcriptome comparisons were performed, and 26, 85 and 85 differentially expressed (DE) miRNA were identified among SS3 vs. SC3, SS12 vs. SC12 and SS24 vs. SC24 respectively, indicating the GSPs treatments could modulate the expression of miRNAs globally. Subsequently, 74, 598 and 1204 target genes of these DE miRNAs were predicted in three comparisons, and GO and KEGG analysis revealed that multiple target genes were associated with proliferation and apoptosis of PC cells. Moreover, interaction network analyis of DE miRNAs and target genes associated with PC were also carried out, and fabulous co-expression relationships further suggested that GSPs treatment could probably repress the proliferation of PC cells by modulating the miRNAs expression

The microRNA, miR-133b, functions to slow Duchenne muscular dystrophy pathogenesis

Project description:Duchenne muscular dystrophy (DMD) is characterized by progressive skeletal muscle degeneration. No treatments are currently available to prevent the disease. While the muscle enriched microRNA, miR-133b, has been implicated in muscle biogenesis, its role in DMD remains unknown. To assess miR-133b function in DMD-affected skeletal muscles, we genetically ablated miR-133b in the mdx mouse model of DMD. In the absence of miR-133b, the tibialis anterior muscle of juvenile and adult mdx mice is populated by small muscle fibers and exhibits increased fibrosis, characterized by thickened interstitial space. Additional analysis revealed that loss of miR-133b exacerbates DMD-pathogenesis partly by altering satellite cell numbers and through widespread transcriptomic changes. These include known miR-133b targets as well as genes involved in cell proliferation and fibrosis. Altogether, our data demonstrate that skeletal muscles utilize miR-133b to mitigate the deleterious effects of DMD.

miRNAs expression profile in ischemic hindlimb muscle of normocholesterolemic (C57) vs hypercholesterolemic (Apoe-/-) mice.

Project description:Using NGS, we report the differential-expression profiling of miRNAs in hypercholesterolemic/atherosclerotic conditions in hindlinb ischemic muscle compare to healthy control mice. Data of total miRNA expression are presented as normalized copy number: read per millions of read (RPM). Hindlimb ischemia was surgicaly induced by feromal artery ablation and the animal was sacrified 1 day after surgery for RNA collection.

miRNA profiling of control and ischemic samples in vitro and in vivo

Project description:miRNA microarray profiling of primary cortical neurons exposed to 4h oxygen and glucose deprivation (OGD) in vitro. RNA samples collected at 8h post-OGD terminaion. miRNAs were also profiled in mice exposed to 3- vessel occlusion model of stroke. RNA samples collected from contralateral (control) and ipsilateral (infarct) sides of the brain following 24h of reperfusion. Comparison of control and ischemic samples across 3 biological replicates for both in vitro and in vivo samples. In vitro cultures consisted of primary cortical neurons derived from E17 rat Wistar embryos. In vivo samples were obtained from C57bl/6 mice exposed to three-vessel occlusion.

Serum miRNA profile in diabetic patients with ischemic heart disease (IHD) as a promising non-invasive biomarker.

Project description:The aim of this study was to conduct a baseline comparison of serum-circulating miRNA in diabetic patients with and without ischemic heart disease. We analysed the expression levels of 798 serum miRNAs using the NanoString nCounter Technology Platform. The prediction of the putative miRNAs targets was performed by the Ingenuity Pathway Analysis (IPA) software. Receiver operating characteristic (ROC) analysis was used to assess the diagnostic value of identified miRNAs. Our data showed that 6 miRNAs are significantly upregulated in type 2 diabetes mellitus (T2DM) patients with IHD compared to T2DM patients without IHD. Functional enrichment analysis of target genes by IPA showed networks and canonical pathways involved in the pathology of the cardiovascular system. All tested miRNAs showed high diagnostic value (AUC > 0.75).
