Non-severe thermal burn injuries induce long lasting gene expression changes in specific cortical neuron and glia cell types

ABSTRACT: Burn injuries are devastating traumas, often leading to life-long consequences that extend beyond the observable burn scar. Burn injury patients commonly develop chronic neurological disorders but the long-lasting impacts of burn injuries on neurons and glia in the brain is unknown. Whole transcriptome RNA-sequencing from cortical excitatory neurons, inhibitory neurons, astrocytes and microglia showed very few changes to the expression of genes with known functions five weeks following a non-severe burn injury in adult mice. However, genes related to GABA-A receptors in excitatory neurons and several cellular functions in microglia was found to be to differentially expressed in burn injured mice. These findings shed light on the long-term effect of burn injuries on the brain and may help identify potential therapeutic targets and windows to prevent neurological dysfunction in burn patients.

Identifying Non-Invasive Molecular Correlates relevant to Irradiation-Skin Burn Combined Injuries

Project description:Currently there is growing concern with respect to scenarios where people are likely to be presented with radiation exposure along with many kinds of other injuries such as trauma and infection. The potential for such scenarios was brought to reality with the events and aftermath of the Fukushima nuclear disaster in Japan. As such medical complications arising from such exposures would be poorly dealt with as no evidence-based guidelines exist for their rehabilitation or recovery. Our research intends to differentially characterize combined radiation and burn injuries and identify novel pathways and biomarkers. Such findings will lead to better medical practices in the diagnosis, care and rehabilitation of affected individuals. The study includes four groups of mice: 1) Control sham mice group (n=4), 2) Skin burn injury mice group (n=6), 3) Radiation injury mice group (n=6), 4) Combined radiation and burn injury mice group (n=6). We propose to characterize the effects of combined radiation and burn injuries using microRNA microarray analysis. Our primary aim is to identify novel molecular pathways and biomarkers specific to whole blood samples (serum) from mice exposed to combined radiation and burn injuries. B6D2F1/J female mice will be used. 30 days following combined radiation and burn injuries arterial blood will be harvested from euthanized mice. 200ul of serum from whole blood samples will be used for microRNA microarray experiments (Affymetrix).

Identification of potential sepsis biomarkers in burn injury conditions.

Project description:12 mice were subjected to one of four treatment groups: no burn injury:no injection, burn injury:no infection, no burn injury:infection, and burn injury:infection. The researchers in this study are looking for metabolites in serum that could indicate sepsis in mice with burn injuries.

Transcription profiling of mouse leukocytes from blood and spleen after burn injury or trauma hemorrhage

Project description:We report here the genes that are sequentially expressed in white blood cells from blood and spleen at 2 hours, 2 day,3 days, and 7 days after burn and sham injury or trauma-hemorrhage (T-H) and sham T-H. Experiment Overall Design: White blood cells (WBC) and splenocytes were harvested from individual mice and RNA was extracted, labeled and hybridized to Affymetrix Mouse Genome 430 2.0 GeneChipsâ¢. The results were analyzed by dCHIP and BRB Array Tools software. Ingenuity Pathway Analysis (IPA) was applied to identify molecular networks significantly affected by the injuries.

Leptin and fractalkine: Novel subcutaneous cytokines in burn injury.

Project description:Burn injury remains a major clinical challenge to both survival and to quality of life. Its progressive, aberrant inflammation underlies the lethal dysfunction of various organs and the pain it induces is excruciating and notoriously difficult to manage. While it is known that burn injury’s complex local and disseminating pathology is orchestrated from the burned tissue, few studies have sought to characterise the local signalling environment. An enhanced understanding of the local and acutely temporally-dynamic processes defining burn injury and its progression is required for the development of novel therapeutic interventions. Microdialysis was used as an interstitial sampling technique, conducted over three hours post-burn. Samples were analysed by metabolomics and a multiplex cytokine immunoassay. Next-Generation sequencing libraries of the burn and control microdialysis sites were prepared to measure transcriptional changes potentially underlying the interstitial profile characterising burn injury.

Identification of plasma extracellular vesicle biomarkers after burn injury

Project description:Severe burn injury is a one of the most devastating forms of trauma with over 1.1 million burns each year requiring medical attention in the United States. Deaths from burn injury are commonly caused by immune-related sequelae such as pneumonia, organ failure and other opportunistic bacterial infections. Though there have been numerous studies to assess the immunological dysfunction associated with burn injury, there have yet to be a predictive biomarker, that can be used to assess high risk patients and their outcomes. We hypothesized that circulating extracellular vesicles (EVs) released early after burn injury would promote activate peripheral macrophages and specific cargo could be used as a biomarker to identify at-risk patients. To test this hypothesis, we assessed the immune consequences of adoptive transfer of EVs isolated after burn injury in vitro and used unbiased proteomic on EVs from mouse models and human burn patients from the UNC Jaycee Burn Center. Findings here suggest EVs serve as mediators of immune dysfunction and potential biomarkers.

Burn Injury (1-7d)

Project description:Animal experiments were performed with male Sprague-Dawley rats (Charles River Laboratories, Boston, MA) weighing 150 ? 200 grams. All experimental protocols used in this study were approved by the Subcommittee on Research Animal Care, Massachusetts General Hospital. Rats were individually housed in a temperature-controlled (25oC) and light-controlled room (12h light-dark cycle) and allowed to adjust to their new surroundings for at least 5 days prior to the experiment. Water and rat chow were provided ad libitum to the animals. On the day of the treatment, the animals were randomly divided into two groups, burned and sham-burned. The burn injury consisted of a full-skin-thickness scald burn of the dorsum, calculated to be ~ 20% of the rat?s total body surface area (TBSA), induced by immersing the designated area in boiling water for 10 s (45). Rats were resuscitated with an intra-peritoneal injection of sterile saline solution (1.5 mL/Kg body weight/% TBSA) immediately after burn. The mortality rate of this treatment was negligible. At each time point (1, 2, 4, and 7d), three animals belonging to each group were sacrificed, the liver and serum collected, and stored at ?80oC after being inflicted with 20% TBSA burn injury. Sham-burn rats (n=3) considered as the control were treated identically except that they were immersed into a 37oC water bath and immediately sacrificed to collect the livers.

Gene response to major burn injuries

Project description:Blood was sampled from severe burns patients over time as well as healthy subjects. Genome-wide expression analyses were conducted using the Affymetrix U133 plus 2.0 GeneChip™. The Inflammation and the Host Response to Injury Large-Scale Collaborative Research Program Blood was sampled from 244 severe burns patients over time as well as 35 healthy subjects who consented to blood sampling. Study subjects were treated under standard operating procedures to minimize treatment variations. Patients had burns covering >20% of the total body surface area and were admitted within 96 hours of injury. Genome-wide expression analyses were conducted using the Affymetrix U133 plus 2.0 GeneChip™.

Human Scarring Project

Project description:Full thickness and deep partial thickness burn injuries heal by scarring. There are several mechanisms thought to be essential for the development of burn scars, but a challenge to studying the skin response to burn injury is that there are few animal models of burn scarring that are either clinically similar to human burn scars or are practical for most investigators to use. The purpose of this study was to examine the changes in RNA expression in human skin to burn injury. This was done by comparing pre-injury tissue from otherwise healthy adults undergoing aesthetic scarification created by branding with a hot metal object to serial samples of untreated wounds in the same subjects.
