Description
TLR4 deficiency attenuates kidney injury after ischemic reperfusion as measured by both renal function and morphology. To better understand the role of TLR4 during the acute kidney injury, we used DNA microarray to identify genes that were differentially expressed on kidneys in wildtype B10 mice and TLR4 null mice during the early stage of injury.

Description
Previously, we found that LZTFL1 is down-regulated in epithelial tumors including lung cancer and functions as a tumor suppressor in gastric cancers. However, the functional role of LZTFL1 in lung oncogenesis is undefined. We show here that downregulation of LZTFL1 expression in non-small cell lung cancer is associated with recurrence and poor survival, while re-expression of LZTFL1 in lung tumor cells inhibited extravasation/colonization of circulating tumor cells to the lung and inhibited tumor growth in vivo. Mechanistically, we found that LZTFL1 is expressed in ciliated human bronchial epithelial cells (HBECs) and its expression correlates with HBEC differentiation. LZTFL1 inhibits TGF-activated MAPK and hedgehog signaling. Alteration of intracellular levels of LZTFL1 resulted in changes of expression of genes associated with epithelial-to mesenchymal transition (EMT). We conclude that LZTFL1 inhibit lung tumorigenesis, possibly by maintaining epithelial cell differentiation and/or inhibition of signalings that lead to EMT, and suggest that reactivation of LZTFL1 expression in tumor cells may be a novel lung cancer therapeutic approach.

Description
A novel systems approach was applied to transcriptome profiling that included the traditional analysis of differentially expressed genes, gene co-expression networks, cell type - specific transcriptomes and a wide range of gene annotations. By integrating our data with previous findings, we generated the first systems hypothesis of human alcoholism that integrates epigenetic regulation of gene expression with structural and functional alterations in alcoholic brain.

Description
Peroxisome proliferator-activated receptors (PPARs) are nuclear hormone receptors that act as ligand-activated transcription factors. Although prescribed for dyslipidemia and type-II diabetes, PPAR agonists have demonstrated therapeutic properties for several brain disorders, including alcohol dependence. PPAR agonists decrease ethanol consumption and reduce withdrawal severity and susceptibility to stress-induced relapse in rodents. However, the cellular and molecular mechanisms facilitating these properties have yet to be investigated and little is known about their effects in the brain. We tested three PPAR agonists in a continuous access two-bottle choice (2BC) drinking paradigm and found that tesaglitazar and fenofibrate decreased ethanol consumption in male C57BL/6J mice while bezafibrate did not. Hypothesizing that fenofibrate and tesaglitazar are causing brain gene expression changes that precipitate the reduction in ethanol drinking, we gave daily oral injections of fenofibrate, tesaglitazar and bezafibrate to mice for eight consecutive days and collected liver, prefrontal cortex and amygdala 24 hours after last injection. RNA was isolated and purified using MagMAX-96 Total RNA Isolation Kit. Biotinylated, amplified cRNA was generated using Illumina TotalPrep RNA Amplification Kit and hybridized to Illumina MouseWG-6 v2.0 Expression microarrays.
