RNA-seq of zebrafish sa12692 mutants against WT controls

ABSTRACT: Arrhythmogenic Right Ventricular Cardiomyopathy is a congenital heart disorder characterized by fibrofatty replacement of the myocardium. The exact molecular mechanisms underlying the disease remain to be elucidated and treatment options are limited. The sa12692 mutant line contains a splice site mutation in the plakoglobin gene, resulting in the expression of a truncated protein. This protein is highly similar to the protein expressed in Naxos disease, a recessive form of ARVC. RNA-seq was used to investigate the effect of the sa12692 mutation on gene expression in order to uncover signalling pathways involved in the pathogenesis of ARVC. Gene expression was examined in whole larvae at 5 dpf and in hearts of 1 year old adult fish. Larvae at 5 dpf were selected as this timepoint is equivalent to birth in humans. Adult hearts were selected as ARVC is a disorder of the heart and cardiac symptoms generally manifest in adulthood. Hence, the molecular effect of the mutation could be profiled at two life stages.

mRNA-Seq of whole flies from Drosophila

Project description:We sequenced mRNA from whole flies of females and male of Drosophila melanogaster, D. simulans, D. yakuba, D. ananassae, D. pseudobscura, D. mojavensis, and D. virilis as part of the modENCODE project to validate novel gene models found in D. melanogaster, identify genes differentially expressed between the sexes and sex-specific alternative splicing events, and examine the evolution of gene expression. Comparison of expresssion profiles in female and male whole flies. These are the same samples used to generate the array data found in GSE6640.

Profiling of chromatin deposition bias in RPE-1 cells using Double-click-seq

Project description:We used double-click-seq method to profile chromatin deposition bias in RPE-1 cells. Untreated wild-type, p53 knock-out and several treatments (hydroxyurea, ATR inhibitor, curaxin) and their combinations were profiled for characterizing assymetry during DNA replication.

Gene Function Hypotheses for the Campylobacter jejuni Glycome Generated by a Logic-Based Approach.

Project description:Increasingly, experimental data on biological systems are obtained from several sources and computational approaches are required to integrate this information and derive models for the function of the system. Here, we demonstrate the power of a logic-based machine learning approach to propose hypotheses for gene function integrating information from two diverse experimental approaches. Specifically, we use inductive logic programming that automatically proposes hypotheses explaining the empirical data with respect to logically encoded background knowledge. We study the capsular polysaccharide biosynthetic pathway of the major human gastrointestinal pathogen Campylobacter jejuni. We consider several key steps in the formation of capsular polysaccharide consisting of 15 genes of which 8 have assigned function, and we explore the extent to which functions can be hypothesised for the remaining 7. Two sources of experimental data provide the information for learning-the results of knockout experiments on the genes involved in capsule formation and the absence/presence of capsule genes in a multitude of strains of different serotypes. The machine learning uses the pathway structure as background knowledge. We propose assignments of specific genes to five previously unassigned reaction steps. For four of these steps, there was an unambiguous optimal assignment of gene to reaction, and to the fifth, there were three candidate genes. Several of these assignments were consistent with additional experimental results. We therefore show that the logic-based methodology provides a robust strategy to integrate results from different experimental approaches and propose hypotheses for the behaviour of a biological system.

Gene expression microarray of human pulmonary endothelial cells from patients with Chronic Obstructive Pulmonary Disease in comparison with normal controls

Project description:This experiment was carried out to see if there were any gene expression differences in pulmonary endothelial cells between patients with and without COPD. COPD is an inflammatory condition and although much work has previously been performed to investigate the inflammatory cells in COPD there has not been as much research looking at the endothelium through which inflammatory cells must pass through to reach the lung tissue. In this experiment pulmonary endothelial cells were extracted from whole lung tissue removed at the time of cardiothoracic surgery. This was performed for patients with and without COPD. RNA was extracted using the Qiagen micro RNeasy kits prior to transferring to the University of Birmingham Biosciences department who performed RNA labelling and ran the microarrays. Once the microarrays were performed quality was checked using ArrayQualityMetrics and the COPD group was compared to the non-COPD group using SAM. The experiment was then repeated using another patient group. Genes of interest were validated with qPCR initially before moving on to functional work.

Irisin is a Pro-Myogenic Factor that Induces Skeletal Muscle Hypertrophy and Rescues Denervation-Induced Atrophy

Project description:C2C12 myoblasts were seeded at a density of 25,000 cells/cm2 in a 10cm cell culture dish and differentiated with low serum differentiation medium at 37 °C, 5% CO2 for 72h and further treated with either DB or recombinant Irisin protein (1000ng/ml) for 6h, 12h, 24h and 48h. Myotubes were resuspended in 2ml of TRIzol ® for each 10cm dish and RNA isolation was performed according to the manufacturer s protocol. Purified isolated RNA was then subjected to Illumina bead array sequencing and data analysis, as per in-house protocols (Sciencewerke, Singapore). Only genes that were upregulated or downregulated by 1.5-fold were considered significant. For genes that had multiple probes (with different accession number), only one probe with the highest upregulation or downregulation was taken into consideration.
