The aim of this study is to estimate genetic impact of MCP-1 -2518 and its receptor CCR2 -190 polymorphisms on AgP patients among Turkish individuals and whether MCP-1 genotype effects mRNA levels of Peripheral Blood Mononuclear Cell Leukocyte (PBML) and GCF levels of MCP-1.
Regular exercise is known to produce significant health benefits and to reduce the risk of heart diseases, although how this benefit occurs is not well understood. White blood cells are known to be involved in triggering heart attacks, and which genes are switched on or off in white blood cells determines whether they have beneficial or harmful effects. Previous studies, and studies ongoing in our group, have demonstrated measurement of peripheral blood gene expression (which r...
Study on healthy volunteers is focusing on analysis of transcriptome profile fluctuations in healthy population in three mononuclear cell types (CD4+ cells, CD56+ cells and CD4+CD25+ cells)and should provide a reference for comparison with transcriptomic data of any disease state.Furthermore, metabolome and immunological status are defined on same samples.
Dutasteride is used in the treatment of benign prostate enlargement (BPH).It inhibits conversion of testosterone (T) into the more potent dihydrotestosterone (DHT) to stop prostate (and possibly prostate cancer) growth. DHT regulates the expression of certain genes in the prostate. The pharmacodynamics of DHT reduction in the prostate were never investigated until now, as every measurement would require prostate tissue retrieval, which is medically and ethically unacceptable. ...
In this study, prednisone dose, day/time administration will be controlled in a stable COPD patient population to determine its effect on peripheral whole blood gene expression. This data has never been collected in a COPD population using our chosen platform for gene expression (Affymetrix Human Gene 1.1 ST). Conducting this experiment is essential for achieving the broader aims of an already existing and related study titled "Clinical Implementation and Outcomes Evaluation of...
Hypothesis: The investigators hypothesize that genetic variants will alter gene expression in response to ischemia during cardiopulmonary bypass. To test this, the investigators will be taking small pieces of heart tissue from patients undergoing heart surgery before and after this period of ischemia. This will be compared to blood gene expression in blood cells and analyzed with the patients' genetic profile. This might allow us to assess the amount of inflammation that occurs...
To validate the use of Corus™ CAD blood assay in subjects who are referred for the work-up of coronary artery disease. The study will evaluate the clinical utility of a gene expression test (Corus CAD) in subjects referred for myocardial perfusion imaging (MPI) work-up for suspected obstructive atherosclerotic coronary artery disease (CAD). The Corus CAD is a gene expression test that quantify the expression of multiple genes from circulating peripheral blood cells to detect ...
The aim of this study are (1) To genome-wide profile the gene expression patterns of peripheral blood mononuclear cell (PBMC) in patients with obstructive sleep apnea (OSA) (2) To profile the gene expression patterns change before and after treatment with continuous positive airway pressure (CPAP) (3) To correlate the altered gene expression with the severity of the disease and outcome of OSA patients
The objective of the study is to define the performance of blood-based signatures for Alzheimer's Disease (AD) in different patients populations including AD, non-AD dementia, and non-demented controls.
Background: Exercise represents an important challenge for the homeostasis of the entire body that occurs on a cellular and systemic level in which micronutrients play an important role in regulating the processes that sustain athletic performance. Objective: The investigators measured changes in gene expression of whole blood in a group of athletes and sedentary participants and compared gene modulation before and after nutritional intervention with micronutrients. Methods: Bl...
The purpose of this study is to analyze the gene expression patterns associated with various microenvironmental stresses in tumors to understand their roles in tumor progression and treatment responses. To achieve this goal, we will perform gene expression analysis of the tumor samples collected from an IRB-approved study (IRB #: 4516-05-2R2) International Phase III Study of Chemoradiotherapy versus Chemoradiotherapy Plus Hyperthermia for Locally Advanced Cervical Cancer direct...
Current concepts of the causes of periodontitis implicate a bacterial infection as the primary cause of the disease. Several bacterial species residing in a biofilm on tooth surfaces are closely associated with periodontitis. Chronic periodontitis (CP) is initiated and sustained by bacterial plaque, but host defense mechanisms play an integral role in its pathogenesis. Gene expression profiling is a powerful means of generating comprehensive genome-level data sets on dis...
Analysis of differential gene expression in patients with chronic rhinosinusitis without polyps compared to unaffected patients. Correlation of abnormal gene expression with surgical outcomes.
Parkinson's disease (PD) is the most frequent neurodegenerative disorder after Alzheimer's disease. It is characterized by motor symptoms (rigidity, tremor, slowness of movements), and non-motor symptoms (neuropsychological, psychiatric, pain ...). Neuronal death initiates in the brainstem and extends progressively through the entire cortex. The processes leading to cell death are poorly understood. Pathological cells exhibit abnormal deposits, called Lewy bodies, which contain...

The proposed research intends to construct a set of tissue microarrays containing different types of normal and lung cancer tissues for the study of genes associated with lung cancer. Thus far we have generated a lung cancer tissue arrayusing paraffin embedded archival tissues from 300 lung turmors tissues and 100 adjacent normal tissues. Four- micrometer thickness sections have been cut from the tissue array and were used to survey gene expression status in arrayed tumors usi...
The purpose of this study is to assess the effect of inhaled fluticasone (an inhaled corticosteroid) on the pattern of the lung airway epithelium and alveolar macrophages gene expression of healthy smokers. The investigators hypothesize that the administration of fluticasone will result in reversibility of some of the airway epithelium and alveolar macrophage gene expression changes induced by cigarette smoking.
Arterial thromboembolism constitutes a major risk of atrial fibrillation (AF) requiring antithrombotic therapy. Platelets and microparticles (MPs) are important for hemostasis and thrombosis, their role during AF is not well known. The principal objective of this study is to compare morphologic, functional and proteomics characteristics of blood platelet between AF patients and healthy volunteers.
Background: - Tuberculosis (TB) infection is particularly deadly when it happens in people who are also infected with the human immunodeficiency virus (HIV). However, not much is known about how these two infections affect each other. Some people who have HIV or TB infections develop health problems after they start taking either HIV or TB medications or both. These drugs can improve the body s ability to fight infections, but sometimes this sudden improvement can make...
This study evaluates the effect of acute administration of oral prednisone in white blood cells counts and glucose tolerance and the relationship of these measures with changes in gene expression in healthy volunteers. White blood cells counts, glucose tolerance and gene expression will be study before and after prednisone administration.
The purpose of the study is to investigate in vivo whether a high-dose vitamin D3 oral bolus (2000 micrograms) produces marked vitamin D receptor target gene expression response and whether there is large inter-individual variation. These effects are compared to in vitro treatment of peripheral blood mononuclear cells from these subjects with 25(OH)D.
This study is divided into distinct sample collection and analysis phases. In the sample collection phase investigators will tape strip lesions that are designated for biopsy because they are suspected for melanoma. No biopsies will be taken solely in support of this study; rather patients that present lesions that are to be biopsied—in the context of the standard of care—will be enrolled in the study and will have that lesion(s) tape stripped before the biopsy procedure. ...
