Gene expression profiling of C57BL/6 mouse lung tissue with various treatments using the MA11 array

Project description:Flaxseed (FS), a nutritional supplement consisting mainly of omega-3 fatty acids and lignan phenolics, has potent anti-inflammatory, anti-fibrotic and antioxidant properties. We have shown that dietary FS supplementation ameliorates oxidative stress and inflammation in experimental models of acute and chronic lung injury in mice resulting from diverse toxicants. The development of lung tissue damage in response to direct or indirect oxidant stress is a complex process, associated with changes in expression levels of a number of genes. We therefore postulated that flaxseed may modulate gene expression of vital signaling pathways, thus interfering with the development of tissue injury. We evaluated gene expression in lungs of flaxseed-fed (10% FS) mice under unchallenged, control conditions and 48hrs post-radiation treatment (13.5 Gy). Gene expression levels in lung tissues were analyzed using three arrays for each sample, whereby a total of 28,800 genes were evaluated. C57BL/6 black mice were fed a 10% flaxseed diet for 21 days and/or given 13.5Gy thoracic radiation and sacrificed 48hrs post radiation.

Dietary flaxseed- and radiation-sensitive microRNAs in murine lung

Project description:Murine lung miRNAs were profiled by rodent TaqMan OpenArray after flaxseed feeding and/or radiation exposure Lung tissue was obtained 48 hours after radiation or no exposure from three animals each: flaxseed/no radiation, flaxseed/radiation, control diet/no radiation, control diet/radiation. miRNA profiles were determined by OpenArray.

Cranial Irradiation Impairs Juvenile Social Behavior and Modulates Hippocampal Physiology

Project description:Cranial and craniospinal irradiation are the oldest central nervous system prophylaxis treatments considered for pediatric patients with lymphoblastic leukemia (ALL). However, survivors of childhood ALL that received cranial radiotherapy are at increased risk for deficits in neurocognitive skills. The continuous and dynamic response of normal tissue after irradiation has been identified as one of the causative factors for cognitive changes after cranial radiation therapy. The aim of our study was to investigate the radiation effects on social behavior and neuronal morphology in the hippocampus of adult mice. Twenty-one-day-old male C57BL/6 mice were irradiated with the small-animal radiation research platform (SARRP). Animals were given a single 10-Gy dose of radiation of X-ray cranial radiation. One month following irradiation, animals underwent behavioral testing in the Three-Chamber Sociability paradigm. Radiation affected social discrimination during the third stage eliciting an inability to discriminate between the familiar and stranger mouse, while sham successfully spent more time exploring the novel stranger. Proteomic analysis revealed dysregulation of metabolic and signaling pathways associated with neurocognitive dysfunction such as mitochondrial dysfunction, Rac 1 signaling, and synaptogenesis signaling. We observed significant decreases in mushroom spine density in the Cornu Ammonis 2 of the hippocampus, which is associated sociability processing.

Senescence gene signature of radiation fibrosis

Project description:Radiation lung injury is characterized by early inflammation and late fibrosis. The causes underlying the chronic, progressive nature of radiation injury are poorly understood. Here, we report that the gene expression of irradiated lung tissue correlates with that observed in the lungs in aged animals. We demonstrate that NOX4 expression and superoxide elaboration is increased in irradiated lungs and pneumocytes in a dose dependent fashion. We used microarrays to detail the global programme of gene expression and report that irradiated lung tissue correlates with that observed in the lungs in aged animals. Female C57Bl/Ncr mice, aged 10 weeks were treated with/ without radiation to the thorax with a X-RAD 320 x-ray irradiator at a dose rate of 2.61 Gy/minute. An age-matched cohort of mice received no IR while additional cohorts received 5 Gy in a single dose, 17.5 Gy in a single dose. RNA was extracted and hybridization done on Affymetrix Mouse430_2 microarrays.
