Description
Leukemia cells are considered developmentally 'frozen', and their phenotype is thought to reflect their stage of origin. To gain insights into the cell population from which T-ALL arises, we compared by global gene expression profiling T-ALL samples (n = 10) to different stages of T cell development, following the order from early thymic progenitor (ETP), to triple negative (TN) TN2, to TN3, to TN4, to immature single positive (ISP), to double positive (DP) thymocytes.

Description
Wild type thymi were transplanted into a competitive (wild type hosts), or non-competitive (Rag2-/-c-/-KitW/Wv hosts) environment. Triple negative 2 and 3 (TN2/3) stages were sorted 14 days afetr transplantation and separated for cells of host or donor origin.

Description
Nitrogen mustard (NM) is a vesicant known to target the lung, causing acute injury which progresses to fibrosis. Evidence suggests that activated macrophages contribute to the pathologic response to NM. In these studies, we analyzed the role of lung lipids generated following NM exposure on macrophage activation and phenotype. Treatment of rats with NM (0.125 mg/kg, i.t.) resulted in a time-related increase in enlarged vacuolated macrophages in the lung. At 28 d post exposure, macrophages stained positively for Oil Red O, a marker of neutral lipids. This was correlated with an accumulation of oxidized phospholipids in lung macrophages and epithelial cells, and an increase in bronchoalveolar lavage fluid (BAL) phospholipids. RNA-sequencing analysis revealed that lipid handling pathways under control of the transcription factors LXR, FXR and PPAR-? were significantly altered following NM exposure. Whereas at 1-3 d post NM, FXR and the downstream oxidized low density lipoprotein receptor, Cd36, were increased, Lxr and the lipid extrusion pump targets, Abca1 and Abcg1 were reduced. Treatment of naïve lung macrophages with lipid enriched fractions of BAL collected 3 d after NM resulted in upregulation of Nos2, Apoe and Ptgs2, markers of pro-inflammatory activation, while lipid-enriched BAL collected 28 d post NM upregulated expression of the anti-inflammatory markers, Il10, Cd163, and Cx3cr1, and induced the formation of lipid-laden foamy macrophages. These data suggest that NM-induced alterations in lipid handling and metabolism drive macrophage foam cell formation, potentially contributing to the development of pulmonary fibrosis. Overall design: Alveolar macrophages were collected by gentile message from male wistar rats 1 d or 28 d after intratracheal exposure to NM and from rats intratracheally exposed to PBS. There were three biological replicates per exposure group.

Description
Rett syndrome (RTT) is an X-linked dominant neurodevelopmental disorder caused by mutations in MECP2, encoding methyl-CpG binding protein 2. MeCP2 is a transcriptional repressor elevated in mature neurons and is predicted to be required for neuronal maturation by regulating multiple target genes. Identifying primary gene targets in either Mecp2-deficient mice or human RTT brain has proven to be difficult, perhaps because of the transient requirement for MeCP2 during neuronal maturation. In order to experimentally control the timing of MeCP2 expression and deficiency during neuronal maturation, human SH-SY5Y cells undergoing mature neuronal differentiation were transfected with methylated MeCP2 oligonucleotide decoy to disrupt the binding of MeCP2 to endogenous targets. Genome-wide expression microarray analysis identified all four known members of the inhibitors of differentiation or inhibitors of DNA binding (ID1, ID2, ID3 and ID4) subfamily of helix-loop-helix (HLH) genes as novel neuronal targets of MeCP2. Chromatin immunoprecipitation analysis confirmed binding of MeCP2 near or within the promoters of ID1, ID2 and ID3, and quantitative RT-PCR confirmed increased expression of all four Id genes in Mecp2-deficient mouse brain. All four ID proteins were significantly increased in Mecp2-deficient mouse and human RTT brain using immunofluorescence and laser scanning cytometric analyses. Because of their involvement in cell differentiation and neural development, ID genes are ideal primary targets for MeCP2 regulation of neuronal maturation that may explain the molecular pathogenesis of RTT.

Description
The zinc finger transcription factor growth-factor-independent-1 (Gfi1) has been involved in various cellular differentiation processes. Gfi1 acts as a transcriptional repressor and splicing control factor upon binding to cognate binding sites in regulatory elements of its target genes. Here, we report that Gfi1-deficient mice develop autoimmunity. Gfi1-deficient peripheral B-cells show a hyperproliferative phenotype, leading to expansion of plasma cells, increased levels of nuclear autoantibodies, and immunoglobulin deposition in brain and kidneys. Dysregulation of multiple transcription factors and cell-cycle control elements may contribute to B-cell dependent autoimmunity. Gfi1 thus emerges as a novel master-regulator restricting autoimmunity.
