Affymetrix Human Exon 1.0 ST Array [probe set (exon) version (huex10st)
Description
Platelets have multiple roles in cancer cell metastasis. In this work we employed exon microarray technology to address platelet gene expression in metastatic non small cell lung cancer versus controls without cancer. We found that 197 of the 200 genes with the most significantly altered expression levels had their expression levels downregulated.

Description
Growth and patterning of the face relies on several small buds of tissue, the facial prominences, which surround the primitive mouth. Beginning around E10 of mouse development the prominences undergo rapid growth and morphogenesis. By E11.5 the medial nasal prominences are in close apposition in the midline, as are the maxillary and medial nasal prominences on either side of the developing face. Subsequently, by E12.5 the nasal and maxillary prominences fuse to form a continuous shelf at the front of the face - the primary palate. Individual prominences are associated with specific developmental processes, and this is reflected by patterns of differential gene expression that give the prominences their unique identities. Thus, only the mandibular and maxillary prominences give rise to dentition while the frontonasal prominence has a unique role in olfaction, and the mandibular prominence in taste. We used microarrays to detail the differential gene expression program in each of the mandibular, maxillary, and frontonasal prominences during the key developmental timepoints of E10.0 through E12.5.

Description
Maize is highly sensitive to short term flooding and submergence. We aimed to discover genetic variation for submergence tolerance in maize and elucidate the genetic basis of submergence tolerance through transcriptional profiling of contrasting genotypes. A diverse set of maize nested association mapping (NAM) founder lines were screened, and two highly tolerant (Mo18W and M162W) and sensitive (B97 and B73) genotypes were identified. Transcriptome analysis was performed on these inbreds to provide genome level insights into the molecular responses to submergence. Overall design: RNA deep sequencing of shoot tissue from four inbreds (B73, B97, Mo18W and M162W) in three conditions 24h control (non-submerged), 24h submerged and 72h submerged.
Publication Title
Genetic and molecular characterization of submergence response identifies Subtol6 as a major submergence tolerance locus in maize.

Description
This investigation provides a robust multi-dimensional compendium of gene expression data relevant to mouse facial development. It profiles the transcriptome ofectoderm and mesenchyme from the three facial prominences in a time series encompassing their growth and fusion. Analysis of the dataset identified more than 8000 differentially expressed genes comprising dramatically different ectoderm and mesenchyme programs. The mesenchyme programs included many genes identified in earlier analyses as well hundreds of genes not previously implicated in craniofacial development. The ectoderm programs included over a thousand genes that highlight epithelial structure, cell-cell interactions and signaling.

Description
The mammary gland of the lactating mouse synthesizes and secretes milk lipid equivalent to its entire body weight in a single 20 day lactation cycle, making it one of the most active lipid synthetic organs known. To test the hypothesis that multiple metabolic control points and potential regulatory mechanisms are involved in activating lipid and lactose synthesis at the onset of lactation we compared the mammary transcriptome of 130 genes involved in glucose metabolism between late pregnancy and early lactation and in response to dietary fat. We utilized data obtained from microarray analysis of mammary glands from quadruplicate FVB mice at pregnancy day 17, and lactation day 2. Diets containing 8% or 40% lipid were fed from lactation days 5 to 10 and mammary glands and livers of triplicate FVB mice prepared for microarray analysis. We also compared the metabolome obtained from magnetic resonance spectroscopy of flash frozen glands of the mammary gland at day 17 of pregnancy with that at day 2 of lactation. The results provide a global picture of the multiple metabolic strategies utilized to turn a quiescent organ into an incredibly efficient machine for massive but balanced lipid and lactose synthesis and implicate the transcription factor SREBP-1c in regulation of part of the pathway.

Description
Abnormal function of genes is at the root of most cancers, but heritable cancer syndromes account for a very small minority of all tumors in humans and domestic animals. The majority of cancers are sporadic, that is, they are not heritable in the strictest sense. Instead, sporadic cancers occur due to interactions of unknown intrinsic (heritable) and environmental factors that lead to malignant transformation and uncontrolled growth. Identification of heritable risk factors in sporadic human cancers is difficult because individual genetic backgrounds are very heterogeneous. To this end, individual genetic backgrounds of purebred dogs are more homogeneous, and dog breeds show different predilection to develop specific cancers. Here, we used genomic screens based on gene expression profiling to identify sets of genes that may contribute to the development of canine hemangiosarcoma, a relatively common endothelial sarcoma. Specific genes in a single breed (Golden Retrievers) are modulated by (or with) heritable risk traits, showing functional features that appear to modulate tumor behavior. Our results suggest these methods are suitable to identify genes that will enhance our understanding of how these cancers happen, as well as possible treatment targets that will improve outcomes of both human and canine cancer patients.

Description
The gastrointestinal tract is a major site of early HIV-1 replication and death of CD4+ T cells. As HIV-1 replicates in the gut, the protective epithelial barrier gets disrupted, leading to the entry of bacteria into the underlying tissue and the bloodstream, leading to inflammation and clinical complications even in HIV-1-infected patients taking antiviral drugs. Counteracting these pathogenic processes may require in-depth understanding of the molecular pathways that HIV-1 and microbes utilize to infect, functionally alter and/or kill CD4+ T cells. However, to date, the nature of the genes altered by relevant HIV-1 strains and bacteria in intestinal CD4+ T cells remains unclear.

Description
Arabidopsis thaliana MYB80 (formerly MYB103) is expressed in the tapetum and microspores between anther developmental stages 6 and 10. MYB80 encodes a MYB transcription factor that is essential for tapetal and pollen development. In order to identify the genes regulated by MYB80, microarray technology was employed to analyze the expression levels of genes that were differentially regulated in the myb80 mutant and wild- type anthers.
Publication Title
The MYB80 transcription factor is required for pollen development and the regulation of tapetal programmed cell death in Arabidopsis thaliana.
