Our understanding of Ewing's sarcoma development mediated by the EWS/FLI fusion protein has been limited by a lack of knowledge regarding the tumor cell of origin. To circumvent this, we analyzed the function of EWS/FLI in Ewing's sarcoma itself. By combining retroviral-mediated RNA interference with reexpression studies, we show that ongoing EWS/FLI(More)
Upregulation of the immune response may be involved in the pathogenesis of schizophrenia with changes occurring in both peripheral blood and brain tissue. To date, microarray technology has provided a limited view of specific inflammatory transcripts in brain perhaps due to sensitivity issues. Here we used SOLiD Next Generation Sequencing to quantify(More)
ORP8 is a previously unexplored member of the family of oxysterol-binding protein-related proteins (ORP). We now report the expression pattern, the subcellular distribution, and data on the ligand binding properties and the physiological function of ORP8. ORP8 is localized in the endoplasmic reticulum (ER) via its C-terminal transmembrane span and binds(More)
Brain-derived neurotrophic factor and neurotrophin-4 high-affinity receptor tropomyosine related kinase (Trk) B is required for the differentiation and maintenance of specific neuron populations. Misregulation of TrkB has been reported in many human diseases, including cancer, obesity and neurological and psychiatric disorders. Alternative splicing that(More)
OBJECTIVE In order to conduct postmortem human brain research into the neuropatho-logical basis of schizophrenia, it is critical to establish cohorts that are well-characterized and well-matched. The aim of the present study was therefore to determine if specimen characteristics including: diagnosis, age, postmortem interval (PMI), brain acidity (pH),(More)
The glucocorticoid receptor (GR) has a critical role in determining the brain's capacity to respond to stress, and has been implicated in the pathogenesis of psychiatric illness. We hypothesized that key changes in cortical GR occur during adolescence and young adulthood, at a time when individuals are at increased risk of developing schizophrenia, bipolar(More)
Akt is a critical regulator of cell growth, proliferation, and survival that is activated by phosphatidylinositol 3-kinase (PI3K). We investigated the effect of PI3K inhibition on activation of sterol regulatory element binding protein-2 (SREBP-2), a master regulator of cholesterol homeostasis. SREBP-2 processing increased in response to various cholesterol(More)
Cholesterol accumulation and removal are regulated by two different transcription factors. SREBP-2 (sterol-regulatory-element-binding protein-2) is best known to up-regulate genes involved in cholesterol biosynthesis and uptake, whereas LXR (liver X receptor) is best known for up-regulating cholesterol efflux genes. An important cholesterol efflux gene that(More)
BACKGROUND The presence of tumor-specific mutations in the cancer genome represents a potential opportunity for pharmacologic intervention to therapeutic benefit. Unfortunately, many classes of oncoproteins (e.g., transcription factors) are not amenable to conventional small-molecule screening. Despite the identification of tumor-specific somatic mutations,(More)
Tropomyosin receptor kinase B (TrkB) is best known as the receptor for brain-derived neurotrophic factor (BDNF). In humans, three major isoforms of TrkB, the full-length receptor (TrkB-TK+) and two C-terminal truncated receptors (TrkB-TK- and TrkB-Shc) are expressed in various tissues. In comparison to TrkB-TK+ and TrkB-TK-, TrkB-Shc is less well(More)
