Plasma Proteome Dynamics in the Pig Model of Trauma

ABSTRACT: The effect of IV-adminstered Vitamin C on the plasma proteome in the pig trauma model was investigated with label free proteomics. Plasma samples were drawn from 9 male Sinclair swine at baseline, post-trauma, and 0.25, 2, and 4 hourspost resuscitation with 500 mL of hydroxyethyl starch. Swine were randomized to receive either saline, low-dose VitC (50 mg/kg), or high-dose VitC (200 mg/kg) during volume resuscitation (N = 3/treatment). High performance LC-MS/MS proteomics was then used to quantitatively measure plasma protein fluctations over time as a function of treatment.

<h4>Background</h4>Fluid resuscitation plays a prominent role in stabilizing trauma patients with hemorrhagic shock yet there remains uncertainty with regard to optimal administration time, volume, and fluid composition (e.g., whole blood, component, colloids) leading to complications such as trauma-induced coagulopathies (TIC), acidosis, and poor oxygen transport. Synthetic fluids in combination with antioxidants (e.g., vitamin C) may resolve some of these problems.<h4>Objectives</h4>We applied ...[more]

Transcriptomic response of murine liver to severe injury and hemorrhagic shock: Affymetrix portion of dual platform

Project description:A dual platform microarray analysis was used to characterize the temporal transcriptomic response in the mouse liver following trauma and hemmorhagic shock Mice were divided into five groups, anesthetized and surgically treated to simulate a time course and trauma severity model: non-manipulated animals (C), minor trauma (MT), 1.5 hour of hemorrhagic shock and severe trauma (HS/T), 1.5 hour HS/T followed by 1 hour resuscitation (HS/T+1.0R), 1.5 hour HS/T followed by 4.5 hours resuscitation (HS/T+4.5R)

Human peripheral blood cells (PB): Effect of Tocilizumab/MRA compared to methotrexate(MTX) treatments on rheumatoid arthritis(RA) patients.

Project description:This microarray study was conducted along with SATORI study, the clinical trial evaluated 125 patients with active RA with an inadequate response to low dose of MTX. Patients were allocated to receive either Tocilizumab(TCZ) 8 mg/kg every 4 weeks (TCZ group) or MTX 8 mg/week (MTX/control group) for 24 weeks. Gene expression profiles (GEP) of 112 patients - 54 patients from TCZ group and 58 patients from MTX group - were obtained in this study.

MeHg-induced encephalopathy

Project description:In this dose series pregnant CD-1 (outbred) dams were exposed to methylmercury (MeHg) as monomethylmercuric chloride injected intraperitoneally on 9 d.p.c. Test doses were 10.0 mg/kg and below. This regimen induces symptoms of Fetal Minimata Disease (FMD) in term fetuses. Risks with respect to FMD for the various test doses were 10.0 mg/kg (40% risk), 5.0 mg/kg (20% risk), 2.5 mg/kg (NOAEL), and 1.25 mg/kg (subNOAEL). All measurements were on RNA from the embryonic forebrain (prosencephalon and surrounding tissue) at 3.0h post-treatment.

Collagen induced arthritis plasma proteomic analysis

Project description:The aim of the project is to analyze the plasma proteomic profile of an animal model of arthritis (Collagen Induced Arthritis; CIA) in response to different treatments. For this, plasma samples from mice under five different treatments were analyzed (N=6 per group): Vehicle, CIA, CIA + Δ9-THCA-A (20 mg / kg), CIA + Δ9-THCA-A (20 mg / kg) + T0070907 (5 mg / kg) and CIA + Δ9-THCA-A (20 mg / kg) + SR141716A (5 mg / kg).

Transcriptomic profiling of S2/S3 proximal tubules in response to LPS treatment

Project description:To investigate the mechanisms of endotoxin-mediated kidney injury as well as renoprotective effects of endotoxin preconditioning, we performed manual microdissection of S2/S3 proximal tubules in mice as follows: 1) Non-preconditioned mice subjected to single-dose 5 mg/kg LPS (0111:B4) i.p. for 4 hrs. 2) Non-preconditioned mice subjected to single-dose 5 mg/kg LPS (0111:B4) for 24 hrs. 3) Preconditioned mice subjected to 0.25 mg/kg LPS followed 24 hour later by 5 mg/kg LPS for 4 hrs. 4) Preconditioned mice subjected to 0.25 mg/kg LPS followed 24 hour later by 5 mg/kg LPS for 24 hrs. 5) Control mice (untreated).

2CdA-induced microphthalmia

Project description:In this dose series pregnant CD-1 (outbred) dams were exposed to the 2-chloro analogue of 2'-deoxyadenosine (a metabolic toxin) on 8 d.p.c. Test doses were developed from a teratological series for 2CdA-induced microphthalmia using BMDS modeling software from the US EPA. Benchmark doses for microarray analysis were: 5.0 mg/kg (25% risk), 2.5 mg/kg (5% risk), 1.25 mg/kg (NOAEL), and 0.625 mg/kg (subNOAEL). All measurements were on RNA from the embryo proper at 3.0h post-treatment.

CLARITY study: Expression data from RRMS patients treated with Oral Cladribine versus Placebo at week 96

Project description:The CLARITY trial (NCT00213135) was designed as a double-blind, placebo-controlled study to allow the best comparison of absolute efficacy and safety of oral cladribine in RRMS subjects. 1326 patients with relapsing MS were randomized (1:1:1) to receive cladribine tablets 3.5 mg/kg or 5.25 mg/kg bodyweight or placebo. Gene expression data in whole blood samples at 96 weeks were prepared according to standard Affymetrix protocols Gene expression data in whole blood samples at 96 weeks were available from patients randomized to placebo (n=57), cladribine tablets 3.5 mg/kg (n=62), and cladribine tablets 5.25 mg/kg (n=70).

Transcriptional response of rat cerebrocortical tissue following acute exposure to permethrin or deltamethrin.

Project description:Pyrethroids are neurotoxicants that disrupt nervous system function by interacting with a variety of membrane bound ion channels on neuronal plasma membranes. This study is designed to investigate the transcriptional events downstream of pyrethroid-induced disruption of nervous system excitability. Adult, male Long-Evans rats were orally dosed in vivo with a single dose of either permethrin (1, 10, or 100 mg/kg) or deltamethrin (0.3, 1, 3 mg/kg) at levels that produce only modest behaviroal effects in the whole animal (Wolansky et al. 2006). Transcriptional profiles were obtained from frontal cerebrocortical tissue 6 hours after acute exposure. The primary goals were 1) to identify dose-responsive biomarkers of effect for pyrethroids and 2) identify sensitive intracellular signaling or metabolic pathways sensitive to pyrethroid compounds. Keywords: dose response
