Studies on mature endothelial cells; exploring mechanisms for improvement of cardiovascular diseases
  • organism-icon Homo sapiens
  • sample-icon 66 Downloadable Samples
  • Technology Badge Icon Affymetrix Human Gene 1.0 ST Array (hugene10st)

Description

Transcriptomic analysis of primary human umbilical vein endothelial cells (HUVEC). HUVEC were treated in vitro with CoCl2 to induce hypoxia, high glucose and high glucose plus hypoxia in different intervals (1, 3, 12 hours). Subsequently, the effect of metformin (anti-diabetic drug) on all conditions was studied to take advantage of transcriptomics to prospectively explore the mechanism of this drug to reduce the risk of cardiovascular diseases in type II diabetic patients.

Transcriptomic analysis of primary CD34+ cells. CD34+ cell were induced in vitro with hypoxia (3 hours), high glucose and high glucose plus hypoxia. Subsequently, the effect of metformin (anti-diabetic drug) on all conditions was studied to take advantage of transcriptomics to prospectively explore the mechanism of this drug to reduce the risk of cardiovascular diseases in type II diabetic patients.

Publication Title

Metformin improves the angiogenic potential of human CD34⁺ cells co-incident with downregulating CXCL10 and TIMP1 gene expression and increasing VEGFA under hyperglycemia and hypoxia within a therapeutic window for myocardial infarction.

Using AmpliSeq we have performed quantitative analysis of 20,803 genes in Negative control precursor-miR (NC-Pre-miR) and pre-miR-17 transfected Rheumatoid arthritis Synovial Fibroblasts (RASFs)
  • organism-icon Homo sapiens
  • sample-icon 4 Downloadable Samples
  • Technology Badge IconIon Torrent Proton

Description

Purpose: The goals of this study are to determine the effect of microRNA-17 overexpression on 20,803 human genes in RASFs using Ion ProtonTM System platform. Human RASFs from two RA patients were transfected with pre-miR-17 or NC-pre-miR for 48 h and total RNA was prepared using miRNeasy kit (Qiagen). Total RNA integrity was checked using an Agilent Technologies 2100 Bio analyzer (Santa Clara, CA). 10 ng of high quality RNA was used to make cDNA for amplification with the Ion AmpliSeq Transcriptome Human Gene Expression kit (ThermoFisher Scientific). The cDNA was subjected to 12 cycles of amplification with panel primers and barcoded with adapters as recommended. Resulting sequencing libraries were quantified by qPCR using SYBR FAST master mix from KapaBiosystems (Wilmington, MA). Sets of eight libraries were balanced, pooled and sequencing beads produced on an Ion Chef. Sequencing was performed on an Ion P1 semi-conductor sequencing chip using an Ion Proton™ System (ThermoFisher Scientific, Grand Island, NY). Data was collected and primary analysis performed using Torrent Suite software version 5.0.3. Reads were mapped to the panel and expression values determined. R Software version R-3.2.3 was used to generate heatmap. Among the panel of 20,803 genes, the expression of 15,067 genes as shown in the representative heat map was observed in pre-miR-17 and NC-pre-miR transfected RASFs. A total of 664 significantly modulated genes (301 upregulated and 363 downregulated) using Student ‘t’ test were further utilized for the IPA analysis. The result of IPA predicted the protein ubiquitin pathway as a major canonical pathway affected by the differentially regulated genes. Interestingly, IPA analysis generated an interactome that showed connectivity among various ubiquitin ligases, NF-?B family, AP-1/cJun, 20S and 26S proteasome system. Conclusion: Our results clearly shows the major pathways affected by miR-17 overexpression in RASFs were Protein ubiquitination related. Overall design: mRNA profiles of pre-miR-17 and NC-pre-miR transfected RASFs were generated by AmpliSeq, in duplicate, using Ion Proton™ System.

Gene Expression Levels in PiZ mice Compared to Wild-type (Wt)C57Bl/6
  • organism-icon Mus musculus
  • sample-icon 8 Downloadable Samples
  • Technology Badge Icon Affymetrix Mouse Expression 430A Array (moe430a)

Description

Individuals expressing alpha-1-antitrypsin mutant Z protein accumulate misfolded, mutant protein in the liver and are at risk for liver diseases including cirrhosis and hepatocellular carcinoma. Transgenic PiZ mice, a model for this liver disease, display similar pathologies to humans, including inflammation, increases in proliferation, autophagy and apoptosis, accumulation of globules and develop fibrosis and hepatocellular carcinoma with age. Microarrays were used to compare the gene expressions of PiZ mice to wild-type mice in order to identify the pathways that are altered in this disorder.

Oxidative stress contributes to liver damage in a murine model of alpha-1-antitrypsin deficiency.

  • Technology Badge Icon Affymetrix Murine Genome U74A Version 2 Array (mgu74av2)

Description

Summary: Brain trauma is a major cause of morbidity and mortality, both in adult and pediatric populations. Much of the functional deficit derives from delayed cell death resulting from induction of neurotoxic factors that overwhelm endogenous neuroprotective responses.

Publication Title

Gene expression profile changes are commonly modulated across models and species after traumatic brain injury.

Genome-wide profiling of salt fractions maps physical properties of chromatin
  • organism-icon Drosophila melanogaster
  • sample-icon 1 Downloadable Sample
  • Technology Badge Icon Affymetrix Drosophila Genome 2.0 Array (drosophila2)

Description

We applied genome-wide profiling to successive salt-extracted fractions of micrococcal nuclease-treated Drosophila chromatin. Chromatin fractions extracted with 80mM or 150mM NaCl after digestion contain predominantly mononucleosomes and represent calssical 'active' chromatin. Profiles of these low-salt-soluble fractions display phased nucleosomes over transcriptionally active genes that are locally depleted of histone H3.3 and correspond closely to profiles of RNA polymerase II. Nearly quantitative recovery of chromatin is obtained with 600mM NaCl, however, the remaining insoluble chromatin is enriched in actively transcribed regions. Salt-insoluble chromatin likely represents oligonucleosomes that are attached to large protein complexes. Both low-salt extracted and insoluble chromatin are rich in sequences that correspond to epigenetic regulatory elements genome-wide. The presence of active chromatin at both extremes of salt solubility suggests that these salt fractions capture bound and unbound intermediates in active processes, thus providing a simple, powerful strategy for mapping epigenome dynamics.
