Project description:Transcriptional profiling of insulin-sensitive tissues comparing control untreated ZDF rat with ZDF rat treated with three different anti-diabetic drugs and ZLC rat. Four-condition experiment, ZDF vs. anti-diabetic drug treated ZDF and ZLC rat. Biological replicates: 3 control, 3 treated, One replicate per array.
Project description:objection: The immune inflammatory disorders rheumatoid arthritis (RA), psoriatic arthritis (PsA) and psoriasis (Ps) share common pathologic features and show responsiveness to anti-tumor necrosis factor (TNF) agents yet they are phenotypically distinct. The aim of this study was to examine if anti-TNF therapy is associated with divergent gene expression profiles in circulating cells and target tissues of patients with these diseases Method: Peripheral blood CD14+ and CD14- cells were isolated from 9 RA, 12 PsA and 10 Ps patients before and after infliximab (IFX) treatment. Between April 2007 and June 2009, 31 patients with active RA, PsA and Ps who were naïve to anti-TNF agents, were recruited from the Faculty Rheumatology Clinics at the University of Rochester Medical Center after informed, written consent was obtained in a protocol approved by the Research Subjects Review Board at the University of Rochester Medical Center. Of the 31 subjects, 9 had active RA and 12 had PsA despite treatment with Disease Modifying Anti-Rheumatic Drugs (DMARDs). Also, 10 patients with extensive Ps (>5% BSA) documented by a dermatologist, were enrolled and they were examined by a rheumatologist to exclude the presence of inflammatory arthritis. Nineteen healthy controls were also recruited.

Project description:Pathological angiogenesis, the abnormal or excessive generation of blood vessels, plays an important role in many diseases including cancer, diabetic retinopathy, psoriasis, and arthritis. Additionally, increasing evidence supports the close linkage between angiogenesis and inflammation. Snake venoms are a rich natural source of biologically active molecules and carry rich potential for the discovery anti-angiogenic and anti-inflammatory modulators. Here, we isolated and purified a novel protein, ZK002, from the venom of the snake Deinagkistrodon acutus, and investigated its anti-angiogenic and anti-inflammatory activities and mechanisms.
Project description:Unprogrammed macrophage polarization, is associated with diabetic wound ulcers. Nevertheless, development of corresponding drugs is still a challenge. Here, exosomes are isolated from naive bone marrow-derived macrophages (BMDMs) (M0-Exos), inflammatory BMDMs (M1-Exos), and anti-inflammatory BMDMs (M2-Exos), with the aim of pinpointing the exosomes functionality and identify global miRNAs expression profiles.
Project description:Troxerutin (TXR), a potent antioxidant compound shows anti-inflammatory activity and possesses hepatoprotective effect. In this study, we aimed to exploit its anti-arthritic properties using adjuvant induced arthritic model. Using relative quantitative proteomics approach, we also tried to understand the mode of action of TXR at mechanistic details and its possible usage in the treatment of arthritis. Results provide a set of candidate biomarkers for responses to TXR in the arthritis and suggest new modalities of anti-arthritic activities. A number proteins were identified from the joint homogenates of the experimental rats using isobaric tag for relative and quantitative proteomics (iTRAQ) method. The detailed study and validation of these proteins involved may be useful in finding out newer treatment modalities.
Project description:Synovial biopsies of Rheumatoid Arthritis patients with active disease were obtained prior to anti-TNF therapy. Clinical response to anti-TNF treatment was measured 20 weeks later using the EULAR response criteria. Gene expression profiles of patients responding to anti-TNF therapy were compared to non-responders and several genes were found to be differentially expressed between both groups of Rheumatoid Arthritis patients.
Project description:Glucocorticoids are potent anti-inflammatory drugs prescribed in various diseases such as asthma, rheumatoid arthritis and multiple sclerosis. The effects of glucocorticoids have extensively been studied in immune cells. However, the regulation of inflammation by glucocorticoids in endothelial cells remains poorly understood. In this study, we stimulated murine lung endothelial cell line with dexamethasone (100 nM) and IFN-gamma (20 ng/mL) for 24 hours and extracted RNA for RNA-seq.
