Gene expression profiling of C57BL/6 mouse lung tissue with various treatments using the MA10 array

ABSTRACT: 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.

Mammary Gland microRNA profiling in female mice receiving flaxseed or its oil and secoisolariciresinol diglucoside components

Project description:Breast cancer is one of the most leading causes of cancer mortality in the world. A growing body of evidence demonstrates the association between flaxseed (FS) consumption and the reduction of breast cancer risk. Flaxseed (FS) is an oilseed rich in n-3 polyunsaturated fatty acids (PUFA), α-linolenic acid (ALA), in dietary phytoestrogen lignan, secoisolariciresinol diglucoside (SDG), and in fiber. Early-life exposure to FS or to its isolated components was associated with the improvement of the mammary gland (MG) morphogenesis and differentiation, and prevention of the MG carcinogenesis. Here, we investigated the effect of FS as a whole food and its isolated oil (FSO) and lignan (SDG) on the MG microRNA (miRNA) signature, in female mice at a late stage of development. We identified a diet-specific MG miRNA signature. Significantly deregulated miRNAs in response to the 3-weeks intervention were associated with breast cancer. Identified miRNAs targeted genes enriched in MG growth and development and in cancer. These miRNAs could be used as potential biomarkers for breast cancer.

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.

Gene expression data from mouse tracheal mesenchymal cells before and 48hrs after SO2 injury

Project description:The conducting airway epithelium of the rodent and human lung is underlaid by mesenchymal cells that include vasculature, smooth muscle, fibroblasts and cartilage. The goal of this project is to identify cellular and molecular changes in the mesenchyme after injury to the epithelium by exposure to SO2 and which may participate in repair of the epithelium We used Affymetrix microarray analysis to compare transcripts in tracheal mesenchyme before and after SO2 injury. Mice tracheal epithelium and mesenchyme were separate for RNA extraction before and 48hrs after SO2 injury. Sample from 4 mice were pooled for each biological experiment. The experiments were repeated three times for triplicate samples.
