Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
In the hematopoietic microenvironment, endothelial cells (ECs) play an important role in the regulation of hematopoietic cell proliferation and trafficking. We previously demonstrated that EC stimulated with tumor necrosis factor alpha (TNF-) induce the generation of dendritic cells from CD34(+) stem cells, whereas in contrast, interleukins were capable of inducing the proliferation of hematopoietic and myeloid progenitors.

Description
Complete identification of the bone marrow niche remains one of the most progressing fields. Attempts to identify soluble factors involved in stem cell renewal have been less successful. We have previously shown that endothelial cells (EC) can induce the long-term proliferation of hematopoietic progenitor cells (HPC), especially when they had been subjected to an inflammatory stimulus like interleukins (IL) 1.

Description
Neuroinflammation is a key phenomenon in the pathogenesis of many neurodegenerative diseases. Understanding the mechanisms by which brain inflammation is engaged and delineating the key players in the immune response and their contribution to brain pathology is of great importance for the identification of novel therapeutic targets for these devastating diseases. Gaucher disease, the most common lysosomal storage disease, is caused by mutations in the GBA1 gene and is a significant risk factor for Parkinson?s disease; in some forms of Gaucher disease, neuroinflammation is observed. An unbiased gene profile analysis was performed on a severely affected brain area of a neurological form of a Gaucher disease mouse at a pre-symptomatic stage; the mouse used for this study, the Gbaflox/flox; nestin-Cre mouse, was engineered such that GBA1 deficiency is restricted to cells of neuronal lineage, i.e., neurons and macroglia. The 10 most up-regulated genes in the ventral posteromedial/posterolateral region of the thalamus were inflammatory genes, with the gene expression signature significantly enriched in interferon signaling genes. Our results imply that the type I interferon response is involved in the development of nGD pathology, and support the notion that interferon signaling pathways play a vital role in the sterile inflammation that often occurs during chronic neurodegenerative diseases in which neuroinflammation is present.

Description
Great interest has been shown in understanding the pathology of Gaucher disease (GD) due to the recently-discovered genetic relationship with Parkinsons disease. For such studies, suitable animal models of GD are required. Chemical induction of GD by inhibition of acid -glucosidase (GCase) using the irreversible inhibitor, conduritol-B-epoxide (CBE), is particularly attractive, although few systematic studies examining the effect of CBE on development of symptoms associated with neurological forms of GD have been performed. We now demonstrate a correlation between the amount of CBE injected into mice and levels of accumulation of the GD substrates, glucosylceramide and glucosylsphingosine, and show that disease pathology, indicated by altered levels of pathological markers, depends on the dose of CBE and its time of injection. Gene array analysis shows a remarkable similarly in the gene expression profile of CBE-treated mice and a genetic GD mouse model, the Gbaflox/flox;nestin-Cre mouse, with 120 of the 144 genes up-regulated in CBE-treated mice also up regulated in Gbaflox/flox;nestin-Cre mice. Finally, we demonstrate that some aspects neuropathology and some behavioral abnormalities can be arrested upon cessation of CBE treatment during a specific time window. Together, our data demonstrate that injection of mice with CBE provides a rapid and relatively easy way to induce symptoms typical of neuronal forms of GD, which will prove particularly useful when examining the role of specific biochemical pathways in GD pathology, since CBE can be injected into mice defective in components of putative pathological pathways, alleviating the need for time consuming crossing of mice.

Description
We investigated the molecular mechanisms for osteolytic bone metastasis by selecting human lung cancer cell line subpopulations with elevated metastatic activity and validating genes that are overexpressed in these cells. A bone-seeking squamous lung cancer cell line (HARA-B4) was established by sequentially injecting parental HARA cells into the left ventricle of male 5-week-old nude mice 4 times.
