Transcription profiling of major depression peripheral blood mononuclear cells (PBMCs) at clinical remission compared to severe acute state

ABSTRACT: PBMCs from major depressive episode (MDE) subjects were obtained at two time points: during a severe episode of depression and eight week later after clinical remission. PBMCs from sex- and age-machted controls were also obtained at an eight weeks interval. PBMC total RNAs from MDE and control subjects were profiled after hybridization with Agilent SurePrint G3 Human GE 8x60K Microarray to identify blood biomarkers of MDE. Total RNAs were extracted from 36 samples including: 9 control and 9 MDE subjects at two point of time (first and eight week later)

To date, it remains impossible to guarantee that short-term treatment given to a patient suffering from a major depressive episode (MDE) will improve long-term efficacy. Objective biological measurements and biomarkers that could help in predicting the clinical evolution of MDE are still warranted. To better understand the reason nearly half of MDE patients respond poorly to current antidepressive treatments, we examined the gene expression profile of peripheral blood samples collected from 16 s ...[more]

Expression data from peripheral blood lymphocytes of major depression, subsyndromal symptomatic depression, and healthy controls

Project description:Several studies have suggested that SSD is a transitory phenomena in the depression spectrum and is thus considered a subtype of depression. However, the pathophysioloy of depression remain largely obscure and studies on SSD are limited. The present study compared the expression profile and made the classification with the leukocytes by using whole-genome cRNA microarrays among drug-free first-episode subjects with SSD, MDD, and healthy controls. We used microarrays to detail the global programme of gene expression to develop blood-based gene expression profiles models for classification of subsyndromal symptomatic depression and major depressive disorder The present study compared the expression profile and made the classification with the leukocytes by using whole-genome cRNA microarrays among drug-free first-episode subjects with SSD, MDD, and matched controls (8 subjects in each group). Support vector machines (SVMs) were utilized for training and testing on candidate signature expression profiles from signature selection step.

Limited systemic sclerosis patients with PAH show biomarkers of inflammation and vascular injury

Project description:Limited systemic sclerosis patients with pulmonary arterial hypertension show biomarkers of inflammation and vascular injury Forty-nine PBMC samples were obtained from 21 lSSc subjects without PAH (lSSc-noPAH), 15 lSSc subjects with PAH (lSSc-PAH), and 10 healthy controls; three subjects provided PBMCs one year later. Genome-wide gene expression was measured for each sample. Gene expression clearly distinguished lSSc samples from healthy controls, and separated lSSc-PAH from lSSc-NoPAH patients. The gene expression and cytokine profiles of lSSc-PAH patients suggest the presence of activated monocytes, and show markers of vascular injury and inflammation. Sample vs reference, total RNA isolated from peripheral blood mononuclear cells (PBMC), 21 lSSc subjects without PAH (lSSc-noPAH), 15 lSSc subjects with PAH (lSSc-PAH), and 10 healthy controls

Gene expression profiles of prostate cancer cell line with or without HDAC inihbitors

Project description:Histone deacetylase (HDAC) inibitors suppress cell proliferation of prostate cancer, but the detailed mechanisms are unknown. Moreover, HDAC includes 18 family members, namely HDAC1-11 and SIRT1-7, and differences of effects on prostate cancer proliferation among these enzymes are also unknown. Thus, we clarified differences of gene expression between prostate cancer cell line (LNCaP) treated with pan-HDAC inhibitors (TSA and OBP-801) or selective HDAC inhibitor (NCC-149, HDAC8-specific inhibitor)using cDNA microarray. LNCaP treated with TSA (1Î¼M), NCC149 (2Î¼M), OBP-801 (200nM) or DMSO for 24hrs, RNA was extracted from cells, and cDNA array was performed.

Gene expressions data of Multiple Sclerosis stages, Clinical Isolated Syndrome and healthy controls

Project description:Clinically Isolated Syndromes (CIS)represent the first clinical episode of an inflammatory demyelinating disorder suggestive of MS. Most CIS will develop relapsing-remitting MS (RR), characterized by clinical and inflammatory attacks followed by periods of recovery and stability. With time, most RR-MS subjects will evolve to secondary progressive MS (SP), with advancing neurological impairment in absence of recognizable relapses. A small fraction of MS subjects experience worsening of neurologic function from the onset and are thus defined primary progressive MS (PP). We analysed PBMC transcriptomes relative to 41 healthy subjects, 47 CIS, 49 RR, 22 SP and 27 PP patients and applied a semi-automated pipeline in R Bioconductor platform to perform preprocessing and differential expression analysis.

Knockdown of STAiR18, an IL-6/STAT3-induced long noncoding RNA, in INA-6 multiple myeloma cells

Project description:STAiR18, an mRNA-like STAT3-induced long noncoding RNA shows ubiquitous expression. RNAi-mediated knockdown of STAiR18 led to a dramatic decrease in INA-6 cell vitality. Furthermore, STAiR18 knockdown reduced the STAT3 RNA and protein levels in these cells, suggesting a positive feedback loop between STAT3 and its target ncRNA STAiR18. Microarray analyses of INA-6 cells after STAiR18 or STAT3 knockdown revealed overlapping changes of transcription patterns indicating a close functional interplay between the two molecules. Taken together, STAiR18 represents a novel noncoding RNA that is likely to play an important role for the oncogenic function of the STAT3 pathway. STAT3- and STAiR18-dependent gene expression in human multiple myeloma cell line INA-6 was measured 40 hours after transfection with either a negative control siRNA, an siRNA to STAT3 or an siRNA to STAiR18. Four independent experiments were performed for each siRNA approach, yielding 12 approaches in total.

The effect of simulated night shift work on the circadian regulation of the human transcriptome

Project description:Eight healthy human subjects were enrolled in a 6-day simulated shift work protocol. Blood samples were collected during the two 24-hour measurement periods. Blood samples were collected every 4 hours during both measurement periods. Subjects entered the lab on Day 1. At the start of Day 2, the first 24-hour measurement period was started. Subjects slept according to their habitual sleep/wake schedule, followed by a 16-hour constant posture procedure. On days 3-6, the sleep period was delayed by 10 hours. Following the third night on this schedule, subjects underwent another 24-hour measurement period. During both measurement periods, 7 blood samples were collected and PBMCs were isolated. mRNA was extracted, labelled, and hybridized to microarrays.

Transcription profiling of human endomyocardial biopsies before, during and after cardiac allograft rejection

Project description:Cardiac allograft rejection remains a significant clinical problem in the early phase after heart transplantation and requires frequent surveillance with endomyocardial biopsy. Endomyocardial tissue samples were obtained in connection with clinical biopsies from twenty consecutive heart transplant patients followed for six months. A rejection episode was observed in 14 patients and biopsies obtained before, during and after the episode were identified. Endomyocardial RNA, from three patients, matching these three points in time were analysed with DNA microarray. Experiment Overall Design: Three subjects (subject number 1,8 and 12) Experiment Overall Design: Three timepoints (Before, during and after an rejection episode)
