Expression data from human PBMCs from breast cancer patients and controls

ABSTRACT: We analyzed gene expression in human peripheral blood mononuclear cells (PBMCs) from breast cancer patients, patients with benign breast abnormalities, healthy cancer-free individuals as well as patients with other types of cancer (gastrointestinal and brain cancers).

Expression data from human PBMCs from breast cancer patients and controls

Project description:We analyzed gene expression in human peripheral blood mononuclear cells (PBMCs) from breast cancer patients, patients with benign breast abnormalities, healthy cancer-free individuals as well as patients with other types of cancer (gastrointestinal and brain cancers). Peripheral blood mononuclear cell (PBMC) samples were collected from women with a suspect initial mammogram prior to undergoing a diagnostic biopsy procedure to determine whether the detected abnormality was benign or malignant. In total, we collected blood from 57 women with a diagnosis of breast cancer and 37 with a benign diagnosis. We also collected blood from 31 women with normal initial mammograms as negative controls and 15 breast cancer patients following surgery. All breast cancer patient samples were collected at the Duke University Medical Center (DUMC) under an institutional review board (IRB)-approved protocol (Duke eIRB#12025) after obtaining informed consent and were provided by Dr. Jeffrey Marks. PBMC samples from patients with various gastrointestinal cancers (n=15) were colelcted and stored at DUMC under IRB-approved protocols (Duke eIRB#12010 and 12025) and were provided by Dr. Jeffrey Marks. Peripheral blood leukocyte samples from patients with brain tumors (n=7) were provided by Dr. John Sampson and were collected by leukapheresis under Duke eIRB#00003877 and #00009403.

Analysis of gene expression in co-culture of PBMCs with breast cancer cell lines by High-Throughput Sequencing

Project description:The goal of this study is to investigate paracrine effect of peripheral blood mononuclear cells (PBMCs) on breast cancer cell lines. Transcription profiles of PBMCs (control) and PBMCs co-cultured with breast cancer cell lines (treatment) were generated by deep sequencing, in triplicate for MCF7 and duplicate for T47D, using Illumina HiSeq 4000. Transcriptome analysis of PBMCs has shown the gene expression changed when co-cultured with breast cancer cell lines. The result revealed significantly up- and down-regulated genes.

microRNA (miRNA) expression profiling of PBMCs of Parkinson's disease (PD) patients and controls

Project description:To investigate the role of miRNAs in the etiology of idiopathic PD, we conducted global miRNA expression profiling in peripheral blood mononuclear cells (PBMCs) of PD patients and controls. Total RNA was extracted from the PBMCs of 19 PD patients and 13 controls, labeled and hybridized to Exiqon microarrays spotted with probes for 733 human miRNAs.

Expression data in PBMCs from SLE patients and controls

Project description:Peripheral blood mononuclear cells were collected from SLE patients in an observational study performed at the University of Michigan Blood microarray expression data were used to confirm the presence of an Interferon signature and identify additional surrogate genes RNA from PBMCs of SLE patients and normal donor controls were obtained for one time point and were profiled on Affymetrix arrays

Sen2020 - Metabolic alteration in PBMCs associated with type 1 diabetes

Project description:Genome-Scale draft model for Human Peripheral Blood Mononuclear Cells (PBMCs). A GEM for PBMCs was developed by applying the INIT algorithm on Human Metabolic Reconstruction (HMR 2.0) as a template model. GEMs were contextualised/ constrained for different conditions using expression datasets. The gene/transcript expression data obtained from PBMCs of Type 1 Diabetes progressors, non-progressors, and healthy controls were employed to score each reaction of HMR 2.0. For further detail please refer to Electronic Supplementary Information of Sen et.al, Metabolic alterations in immune cells associate with progression to type 1 diabetes, Diabetologia, 15/01/2020, (https://doi.org/10.1007/s00125-020-05107-6).

Comprehensive RNA-Seq profiling in PBMCs of ALS patients and healthy controls

Project description:Coding and long non-coding RNA metabolism is now revealing its crucial role in Amyotrophic Lateral Sclerosis (ALS) pathogenesis. In this work, we performed Illumina RNA-seq analysis on Peripheral Blood Mononuclear Cells (PBMCs) from Sporadic and mutated ALS patients (mutations in FUS, TARDBP, SOD1, C9Orf72 and VCP genes) and healthy controls. Our aim is the whole-transcriptome characterization of PBMCs content, both in terms of coding and non coding RNAs, in order to compare the disease state to the healthy controls, both for sporadic patients and for mutated patients. Out dataset is a starting point for the omni-comprehensive analysis of coding and long non coding RNAs, from an easy to withdraw, manage and store tissue that shows to be a suitable model for RNA profiling in ALS.

Gene expression data from CD34+ BMMCs/PBMCs from MPN patients vs. healthy controls

Project description:Philadelphia chromosome-negative myeloproliferative neoplasms (MPN) consist of primary myelofibrosis (PMF), polycythemia vera (PV), essential thrombocythemia (ET) and seconday myelofibrosis (SMF), comprising post-ET-MF(pET-MF) and post-PV-MF(pPV-MF). In this dataset, we compare the gene expression data of bone marrow or peripheral blood mononuclear cells (BMMCs/PBMCs) of CD34+ cells from MPN patients and healthy donors.
