Description
DNA methylation is essential for mammalian development and plays crucial roles in a variety of biological processes. The DNA methyltransferase Dnmt1 serves to maintain parental cell methylation patterns on daughter DNA strands in mitotic cells, however, the precise role of Dnmt1 in regulation of quiescent adult stem cells is not known.
Publication Title
DNA methyltransferase 1 is essential for and uniquely regulates hematopoietic stem and progenitor cells.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
HSF1 is a major transcriptional regulator of heat shock responses. Many cells activate HSF1 in response to heat shock temperatures (>42oC) and other cellular stress causing agents. Unlike other cell types, T cells activate HSF1 in response to T cell activation or when exposed to febrile (40oC) temperatures, suggesting a role for HSF1 beyond the heat-shock response.
Publication Title
Heat shock transcription factor 1 is activated as a consequence of lymphocyte activation and regulates a major proteostasis network in T cells critical for cell division during stress.

Description
Surfactant deficiency, diffuse alveolar damage and respiratory failure caused by loss of Abca3 in AT2 cells was followed by remarkable proliferation of alveolar cells and selective survival of ABCA3 sufficient cells resulting in regeneration of alveolar structure and function, providing the conceptual framework for the development of therapies to ameliorate lung diseases caused by mutations in ABCA3 and other genes critical for AT2 cell function or surfactant homeostasis. Overall design: Control and Abca3 cKO AT2 cell RNA-seq at 6 days post tamoxifen in adult mice.

Description
Predicting liver injury after exposure to toxic industrial chemicals is complicated by the large number of potential environmental contaminants, mixtures, and exposure dose and route scenarios. Identifying indicators of end organ injury can complement exposure-based assays and improve predictive power. A multiplexed approach was used to experimentally evaluate a panel of 67 genes predicted to be fibrogenic by computationally mining DrugMatrix, a publicly available repository of gene microarray data. Five-day oral gavage studies in male Sprague-Dawley rats dosed with varying concentrations of three fibrogenic compounds (allyl alcohol, carbon tetrachloride, and 4,4-methylenedianiline) and two non-fibrogenic compounds (bromobenzene and dexamethasone) were conducted. Fibrosis was definitively diagnosed by histopathology. Transcriptomics data matched the predictions made using the DrugMatrix data with greater than 90% accuracy. Microarray data were verified using a 67-plex panel Bioplex assay, confirming that the 67-plex panel constituted a biomolecular signature of hepatic fibrosis (Figure). Necrosis and inflammatory infiltration were comorbid with fibrosis. Interaction analysis identified 24 genes specific for the fibrosis phenotype. The protein product of the gene most strongly correlated with the fibrosis phenotype (Pcolce) was dose-dependently elevated in plasma from animals administered fibrogenic chemicals (p<0.05). PCOLCE is a novel biomarker candidate of fibrotic injury. These results support the development of gene panels for liver injury and may suggest bridging biomarkers for molecular mediators linked to histopathology.

Description
Trascriptional analysis of CD2 hi and CD25 lo CD4+ effector T cells during acute viral infection. SMARTA cells were transferred into B6 mice, followed by infection with LCMV. At day 5 post-infection, CD25 hi and CD25 lo SMARTA cells were isolated from the spleen by FACS. Consistent with our prior studies showing that CD25 lo early effector cells give rise to both Tfh effector cells and memory T cells, we observed gene expression in the CD25 lo population consistent with Tfh differentiation. Conversely, CD25 hi effector cells expressed markers consistent with Th1 differentiation and short-term survival. Overall design: mRNA profiles of monoclonal transgenic CD4+ T cells with divergent CD25 surface expression 5 days post LCMV infection in mice
