We performed a comparative genomics approach between im mutant and TM-1 in order to understand the function of im gene reducing the degree of fiber cell wall development. We compared transcriptome profiles of developing fibers (10, 17, and 28 days post anthesis (DPA)) between two NILs using Affymetrix cotton array chip containing 21,854 transcripts.

View SamplesThere is much evidence suggesting that gene-environment interactions underlying the developmental origins of the metabolic syndrome. Previously, we have induced a metabolic syndrome phenotype in mice though prenatal undernutrition; however, the C57BL/6J strain exhibited significantly more metrics of the metabolic syndrome than the A/J strain.

View SamplesSTAT3 is an immidiate regulator of Th17 differentiation. STAT3 difieciency downmodulate Th17 specific genes and Th17 responses. Therefore, we intend to identify genome wide targets of STAT3.

View SamplesExtracellular superoxide dismutase (SOD3), which dismutases hydrogen peroxide to superoxide anion at cell membranes, mimics RAS oncogene action inducing primary cell immortalization at sustained low-level expression while high expression activates cancer barrier signaling through p53-p21 growth arrest pathway. We have previously demonstrated that the growth regulation of SOD3 occurs at the level of RAS and is mediated through non-transcriptional and transcriptional routes. Therefore, in the current work we assayed the growth suppressive mechanisms of SOD3 by characterizing the main signal transduction routes from the cell membrane into the nucleus. Based on our data robust over-expression of SOD3 in anaplastic thyroid cancer 8505c cells increased EGFR, RYK, ALK, FLT3, and EPHA10 tyrosine kinase receptor phosphorylation with consequent downstream SRC, FYN, YES, HCK, and LYN kinase activation. However, RAS pull-down experiment suggested lack of mitogen pathway stimulation that was confirmed by MEK1/2 and ERK1/2 Western blot. Interestingly, mRNA expression analysis indicated that SOD3 regulated in a dose dependent manner the expression of selected guanine nucleotide exchange factors (Rho GEF16, Ral GEF RGL1), GTPase activating proteins (ArfGAP ADAP2, Ras GAP RASAL1, RGS4), and Rho guanine nucleotide disassociation inhibitors (Rho GDI 2) therefore controlling the signal transduction through RAS GTPases to downstream signal transduction pathways. Our current data suggests a SOD3-induced activation of growth signal transduction is controlled in a dose dependent manner through GEF, GAP, and GDI.

View SamplesMice lacking topoisomerase II (Top II) are known to exhibit a perinatal death phenotype. In the current study, transcription profiles of the brains of wild type and top2 knockout mouse embryos were generated. Surprisingly, only a small number (1-4%) of genes were affected in top2 knockout embryos. However, the expression of nearly 30% of developmentally regulated genes was either up- or down-regulated.

View SamplesThe tissue-specific pattern of mRNA expression can indicate important clues about gene function. High-density oligonucleotide arrays offer the opportunity to examine patterns of gene expression on a genome scale. Toward this end, we have designed custom arrays that interrogate the expression of the vast majority of protein-encoding human and mouse genes and have used them to profile a panel of 79 human and 61 mouse tissues. The resulting data set provides the expression patterns for thousands of predicted genes, as well as known and poorly characterized genes, from mice and humans. We have explored this data set for global trends in gene expression, evaluated commonly used lines of evidence in gene prediction methodologies, and investigated patterns indicative of chromosomal organization of transcription. We describe hundreds of regions of correlated transcription and show that some are subject to both tissue and parental allele-specific expression, suggesting a link between spatial expression and imprinting.

View SamplesHigh-throughput gene expression profiling has become an important tool for investigating transcriptional activity in a variety of biological samples. To date, the vast majority of these experiments have focused on specific biological processes and perturbations. Here, we profiled gene expression from a diverse array of normal tissues, organs, and cell lines in mice. Keywords: multiple tissues
