Using RNA sequencing (Illumina Hi-Seq 2000 sequencer) we report the transcriptome profile of primary human chondrocytes isolated from patients with hip osteoarthritis (OA), and the transcriptome response of these cells to 4h stimulation with IL-1ß (1ng/ml). In total, 983 long non-coding RNAs (lncRNAs) were identified, which included 642 intergenic lncRNAs (lincRNAs), 124 antisense and pseudogenes. Less than 4% of the identified lncRNAs overlapped with putative eRNAs regions, and visual inspection showed that they were uni-directional and multi-exonic. Upon IL-1ß stimulation 499 protein-coding genes were differentially expressed, and 158 lncRNAs were differentially expressed, including 92 lincRNAs, 13 antisense and 18 psudogenes. This study demonstrates that IL-1ß induces a rapid and widespread change in the transcriptome of the primary human OA chondrocyte. Overall design: RNA sequencing analysis of primary human chondrocytes isolated from n=3 patients with hip osteoarthritis, with and without 4h IL-1b (1ng/ml) stimulation

View SamplesWhile others have reported that fetal liver contains a population of endothelial progenitors based on expression of cell surface markers or culture assays, this is the first proof of a CD31+Sca1+ progenitor by demonstrating highly efficient in vivo angiogenesis and a direct connection to the host vasculature. We have developed a novel isolation method based on collagenase digestion and culture on a fetal liver-derived feeder layer and demonstrate that the feeder cells or their supernatants are required for endothelial progenitor survival and proliferation. Proteogenomic profiling of the endothelial progenitors and the feeder cells was done with tandem mass spectrometry proteomics using MudPIT and gene transcript expression profiling using high density DNA microarrays. This approach identified a number of gene transcripts, proteins and candidate growth factor pathways that are likely to be involved in endothelial progenitor growth, differentiation and angiogenesis.

View SamplesProliferation of neoplastic plasma cells within the bone marrow leads to reduced oxygen availability. In response to hypoxia, the transcription factor hypoxia-inducible factor-2alpha (HIF-2) is activated and stabilised. We hypothesise that activation of HIF-2 is a central driver of multiple myeloma disease progression, leading to the induction of transcription of genes associated with angiogenesis, osteoclast activation and cell migration. In this study we assessed the affects of HIF-2 overexpression on gene expression in the human myeloma cell line LP-1.

Loss of nuclear TDP-43 in amyotrophic lateral sclerosis (ALS) causes altered expression of splicing machinery and widespread dysregulation of RNA splicing in motor neurones.

View SamplesAims: Loss of nuclear TDP-43 characterises sporadic and most familial forms of amyotrophic lateral sclerosis (ALS). TDP-43 (encoded by TARDBP) has multiple roles in RNA processing. We aimed to determine whether 1) RNA splicing dysregulation is present in lower motor neurons in ALS and in a motor neuron-like cell model, and 2) TARDBP mutations (mtTARDBP) are associated with aberrant RNA splicing using patient-derived fibroblasts.

View SamplesDespite significant improvements in life expectancy of kidney transplant patients due to advances in surgery and immunosuppression, Chronic Allograft Nephropathy (CAN) remains a daunting problem. A complex network of cellular mechanisms in both graft and peripheral immune compartments complicates the non-invasive diagnosis of CAN, which still requires biopsy histology. This is compounded by non-immunological factors contributing to graft injury. There is a pressing need to identify and validate minimally invasive biomarkers for CAN to serve as early predictors of graft loss and as metrics for managing long-term immunosuppression.
