Gene expression analysis of TSC-tubers reveals incre...
Cortical tubers in patients with tuberous sclerosis complex (TSC) are associated with cognitive disability and intractable epilepsy. While these developmental malformations are believed to result from the effects of TSC1 or TSC2 Gene mutations, the molecular mechanisms leading to tuber formation during brain development as well as the onset of seizures remain largely unknown. We used the Affymetrix Gene Chip platform as a genome-wide strategy to define the Gene expression profile of cortical ...

Gene expression analysis of macrophages from ankylos...
OBJECTIVE: To determine whether macrophages, a type of cell implicated in the pathogenesis of ankylosing spondylitis (AS), exhibit a characteristic gene expression pattern. METHODS: Macrophages were derived from the peripheral blood of 8 AS patients (median disease duration 13 years [range <1-43 years]) and 9 healthy control subjects over 7 days with the use of granulocyte-macrophage colony-stimulating factor. Cells were stimulated for 24 hours with interferon-gamma (IFNgamma; 100 units/ml), ...

Gene expression changes in blood RNA after swimming ...
Trihalomethanes (THM) are a class of disinfection by-products in chlorinated waters linked to deleterious health effects in humans although biological mechanisms are unclear. We aimed to study short-term changes in blood gene expression of adult recreational swimmers associated with physical activity and THM exposure.Adult volunteers (18-50 years, non-smokers, non-asthmatics) swam 40 minutes in an indoor chlorinated pool in Barcelona. Blood samples and THM measurements in exhaled breath were ...

Gene expression data of skin from psoriatic patients...
Gene expression has been proposed as an intermediate phenotype that can increase power in complex trait gene-mapping studies. Psoriasis, an immune-mediated, inflammatory and hyperproliferative disease of the skin and joints, provides an ideal model system to evaluate this paradigm, as conclusive evidence demonstrates that psoriasis has a genetic basis and the disease tissue is readily accessible.To better understand the complex nature of processes in psoriasis, we characterize gene expression...

Gene expression in RNP autoantibody+ systemic lupus ...
The goal of this study was to characterize gene expression profiles in RNP autoantibody+ SLE versus healthy blood donors with a focus on select cytokines that may be important in B cell activation and differentiation, including BAFF, IL-21, and IL-33. We utilized Affymetrix microarrays to characterize the global program of gene expression in the SLE patients, and to identify differentially expressed genes in patients compared to healthy controls. We examined a cohort of 79 consecutive patient...

Gene expression in psoriasis lesions and uninvolved skin
psoriasis is a chronic inflammatory skin disease characterized by marked proliferation of keratinocytes leading to pronounced epidermal hyperplasia, elongation of rete ridges and hyperkeratosis. The most common form of psoriasis, chronic plaque psoriasis (Psoriasis vulgaris), involves relatively stable occurrence and progression of sharply demarcated lesions, usually on the trunk and extremities, which share a combination of trademark histological features, including tortuous and dilated derm...

Gene expression profiles associated with acute myoca...
Whole peripheral blood samples collected into Paxgene tubes from 338 adult participants in the Emory University Cardiovascular Biobank, in Midtown Atlanta. The sample is of mixed cardiovascular function diversity, and is part of a survey of the impact of status of cardiovascular disease on gene expression and clinical attributes. Sample annotations only include gender and proofed ethnicity for purposes of IRB, as well as technical features of the study (plate, phase of study, and RNA quality...
