Project description:The conditioned media from Bifidobacterium infantis (BCM) and Lactobacillus acidophilus (LCM) were reported to promote maturation of innate immune response gene expression, which explained the protective effects of probiotics in clinical necrotizing enterocolitis. We used microarray analysis to investigate the expression of genes involved in regulation of BCM and LCM in IL-1β stimulated immature human enterocytes. The H4 cells (a human nontransformed primary intestinal epithelial cell line) were pretreated with BCM or LCM (15%) for 30 minutes, and then stimulated with or without IL-1β (10 ng/mL) for 4 h. Cell media and IL-1β stimulation were negative and positive control, respectively. RNA was extracted for mcroarray analysis. A total of six treatments (triplicates for each) were included in this study. As one RNA sample in IL-1β-stimulated cells treated with BCM was dropped due to bad quality, seventeen samples were analyzed. Various treatments were compared to the nagative control (cell media alone). Genes with a fold-change ≥2 and a p value ≤ 0.05 were selected.

Project description:We report the differential mRNA expression of memory-like CD4+ T cells stimulated with iL-7, IL-1β, and IL-23. We found memory-like CD4+ T cells stimulated with IL-1β, or with IL-1β and IL-23, in the presence of IL-7, displayed a unique gene expression signature.

Project description:Osteoarthritis is a chronic disease characterised by the loss of articular cartilage in synovial joints through a process of extracellular matrix destruction that is strongly associated with inflammatory stimuli. Chondrocytes undergo changes to their protein translation capacity during osteoarthritis, but a study of how disease-relevant signals effect chondrocyte protein translation at the transcriptomic level has not previously been performed. In this study we describe how the inflammatory cytokine interleukin 1-beta (IL-1β) rapidly affects protein translation in the chondrocytic cell line SW1353. Using ribosome profiling we demonstrate that IL-1β induced altered translation of inflammatory-associated transcripts such as NFKB1, TNFAIP2, MMP13, CCL2 and CCL7, as well as a number of ribosome-associated transcripts, through differential translation and the use of multiple open reading frames. Proteomic analysis of the cellular layer and the conditioned media of these cells identified that proteins which were differentially translated were most readily detected in the secretome. These translationally regulated secreted proteins included a number of chemokines and cytokines, underlining the rapid, translationally-mediated inflammatory cascade that is initiated by IL-1 β.

Project description:Osteoarthritis (OA) is an age-related degenerative musculoskeletal disease characterised by loss of articular cartilage, synovitis, abnormal bone proliferation and subchondral bone sclerosis. Underlying OA pathogenesis is yet to be fully elucidated with no OA specific biomarkers in clinical use. Ex-vivo equine cartilage explants (n=5) were incubated in TNF-α/IL-1β supplemented culture media for 8 days, with media removed and replaced at 2, 5 and 8 days. Acetonitrile metabolite extractions of 8 day cartilage explants and media samples at all time points underwent 1D 1H nuclear magnetic resonance metabolomic analysis with media samples also undergoing mass spectrometry proteomic analysis. Within the cartilage, metabolites glucose and lysine were elevated following TNF-α/IL-1β treatment whilst adenosine, alanine, betaine, creatine, myo-inositol and uridine levels decreased. Within the culture media, four, four and six differentially abundant metabolites and 154, 138 and 72 differentially abundant proteins, with > 2 fold change, were identified for 1-2 day, 3-5 day and 6-8 day time points respectively. Nine potential novel OA neopeptides were elevated in treated media. Our novel study identified metabolites, proteins and extracellular matrix derived neopeptides which provides insightful information on OA pathogenesis, enabling potential translation for clinical markers and possible novel therapeutic targets.

Project description:Osteoarthritis (OA) is an age-related degenerative musculoskeletal disease characterised by loss of articular cartilage, synovitis, abnormal bone proliferation and subchondral bone sclerosis. The underlying pathogenesis of OA is yet to be fully elucidated with no OA specific biomarkers in clinical use. Nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry (MS) allow identification of the global metabolome and proteome respectively. During this study, ex-vivo equine cartilage explants (n=5) were incubated in TNF-α/IL-1β supplemented culture media for 8 days, with media removed and replaced at 2, 5 and 8 days. Acetonitrile metabolite extractions of 8 day cartilage explants and media samples at all time points underwent 1H NMR metabolic analysis with media samples also undergoing MS proteomic analysis. Within the cartilage, metabolites glucose and lysine were elevated following TNF-α/IL-1β treatment whilst adenosine, alanine, betaine, creatine, myo-inositol and uridine levels decreased. Within the culture media, four, four and six metabolites were identified as being differentially abundant between control and treatment groups for 1-2 day, 3-5 day and 6-8 day time points respectively. Culture media proteomics identified 154, 138 and 72 proteins differentially abundant, with > 2 fold change, between control and treatment groups for 1-2 day, 3-5 day and 6-8 day time points respectively. Nine potential novel OA neopeptides were elevated in treated media. This is the first study to use a multi ‘omics’ approach to simultaneously investigate the metabolomic profile of ex-vivo cartilage and metabolomic/proteomic profiles of culture media using the TNF-α/IL-1β ex-vivo OA cartilage model. This study has identified a panel of metabolites, proteins and extracellular matrix derived neopeptides which are differentially abundant during an early phase of the OA model which may provide further information on underlying disease pathogenesis, allow potential translation for clinical markers and possible novel therapeutic targets.
