Gene expression profile of peripheral blood mononuclear cells may contribute to the identification and immunological classification of breast cancer patients.

It has been reported that the gene expression profile of peripheral blood mononuclear cells (PBMCs) exhibits a unique gene expression signature in several types of cancer. In this study, we aimed to explore the breast cancer patient-specific gene expression profile of PBMCs and discuss immunological insight on host antitumor immune responses.

IL8 and EDEM3 gene expression ratio indicates peripheral blood mononuclear cell (PBMC) quality.

Uncontrolled preanalytical variables can reduce the accuracy and reproducibility of downstream analytical results from peripheral blood mononuclear cells (PBMCs).

Decreased Gene Expression of Epstein-Barr Virus-Induced Gene 3 (EBI-3) may Contribute to the Pathogenesis of Rheumatoid Arthritis.

Interleukin-35 (IL-35) is a member of the IL-12 family of heterodimeric cytokines produced by regulatory T (Treg) cells. This immunosuppressive cytokine can prevent exaggerated inflammatory responses like those responsible for the development of rheumatoid arthritis (RA). This study aims to determine the correlation between the gene expression of Epstein-Barr virus-induced gene 3 (EBI-3) and IL-12A (p35) subunits of IL-35 in peripheral blood leukocytes with immunological and clinical parameters in RA patien...

Comparison of gene expression and flow cytometry for immune profiling in chronic lymphocytic leukaemia.

Understanding how cancer and cancer therapies affect the immune system is integral to the rational application of immunotherapies. Flow cytometry is the gold standard method of peripheral blood immune cell profiling. However, the requirement for viable cells can limit its applicability, especially in studies of retrospective clinical cohorts. We aimed to determine if gene expression, analysed using the NanoString platform, could be used to quantify the immune populations present in cryopreserved peripheral ...

CLEC4C gene expression can be used to quantify circulating plasmacytoid dendritic cells.

Plasmacytoid dendritic cells (pDC) are an important type I interferon producer that play an important role in the first line of host defence during viral infection. Abnormalities in pDC numbers and function have been associated with several health conditions. Quantifying pDC is important for understanding pDC related immune responses in viral infections and other diseases, however the current methods for quantifying pDC using flow cytometry have limited utility in large cohort studies involving multiple cen...

GECO: gene expression correlation analysis after genetic algorithm-driven deconvolution.

Large-scale gene expression analysis is a valuable asset for data-driven hypothesis generation. However, the convoluted nature of large expression datasets often hinders extraction of meaningful biological information. Results: To this end, we developed GECO, a gene expression correlation analysis software that uses a genetic algorithm-driven approach to deconvolute complex expression datasets into two subpopulations that display positive and negative correlations between a pair of queried genes. GECO's mut...

Classification of tumor microenvironment immune types based on immune response-associated gene expression.

In 2014, the Shizuoka Cancer Center launched project High‑tech Omics‑based Patient Evaluation (HOPE), which features whole exome sequencing (WES) and gene expression profiling (GEP) of fresh surgical specimens from cancer patients. With the development of clinical trials of programmed death‑1 (PD‑1)/PD‑ligand 1 (PD‑L1) blockade, PD‑L1 expression and a high tumor mutation burden become possible biomarkers that could be used to predict immune responses. In this study, based on WES and GEP da...

Identification of gene expression predictors of occupational benzene exposure.

Previously, using microarrays and mRNA-Sequencing (mRNA-Seq) we found that occupational exposure to a range of benzene levels perturbed gene expression in peripheral blood mononuclear cells.

Transcriptome analysis of immune genes in peripheral blood mononuclear cells of young foals and adult horses.

During the neonatal period, the ability to generate immune effector and memory responses to vaccines or pathogens is often questioned. This study was undertaken to obtain a global view of the natural differences in the expression of immune genes early in life. Our hypothesis was that transcriptome analyses of peripheral blood mononuclear cells (PBMCs) of foals (on day 1 and day 42 after birth) and adult horses would show differential gene expression profiles that characterize natural immune processes. Gene ...

Analysis of Helios gene expression and Foxp3 TSDR methylation in the newly diagnosed Rheumatoid Arthritis patients.

The control of auto-reactive cells is defective in rheumatoid arthritis (RA). Regulatory T (Treg) cells which play a key role in the modulation of immune responses have an impaired function in RA. Foxp3 is a master regulator of Treg cells which its expression is under the tight control of epigenetic mechanisms. In the current study, we analyzed the epigenetic modulation of the Foxp3 Treg-specific demethylated region (TSDR) and Helios gene expression to determine Treg cells alteration in RA patients.

Impact of GADD34 on Apoptosis of Tonsillar Mononuclear Cells from IgA Nephropathy Patients by Regulating Eif2α Phosphorylation.

Tonsillectomy may be an important method to achieve a long-term remission of IgAN, but patients' physical status may limit their access to this surgery. We proposed an encouraging solution through inhibiting GADD34 expression in order to promote tonsillar mononuclear cells (TMCs) apoptosis and reduce nephropathic IgA secretion.

Gene Signature of Proliferating Human Pancreatic α-Cells.

Pancreatic α-cells proliferate with low rate and little is known about the control of this process. Here we report the characterization of human α-cells by large-scale single cell RNA sequencing coupled with pseudotime ordering. We identified two large subpopulations and a smaller cluster of proliferating α-cells with increased expression of genes involved in cell cycle regulation. The proliferating α-cells were differentiated, had normal levels of GCG expression and showed no signs of cellular stress. ...

A two-step immunomagnetic separation of somatic cell subpopulations for a gene expression profile study in bovine milk.

The objective of this study was to demonstrate the usefulness of an immunomagnetic method to purify subpopulations of milk somatic cells. The experiment was conducted on milk samples collected from healthy cows (n = 17) and from cows with clinical mastitis (n = 24) due to a Staphylococcus aureus natural infection. A two-step immunomagnetic purification was applied to simultaneously separate three somatic cell subpopulations from the same milk sample. Total RNA was extracted and qPCR was performed to determi...

Immunological responsiveness of intestinal tissue explants and mucosal mononuclear cells to Ex Vivo stimulation.

There are limited data on the immunological responsiveness of healthy intestinal tissue when it is cultured and stimulated ex vivo. Such an ex vivo model has the potential to be a valuable tool in understanding disease pathogenesis and as a preclinical tool for the assessment of candidate therapeutic agents used to treat inflammatory bowel disease (IBD).

Why Is the Immunoglobulin Heavy Chain Gene Mutation Status a Prognostic Indicator in Chronic Lymphocytic Leukemia?

The immunoglobulin heavy chain gene (IgHV) mutation status correlates with the clinical outcome of patients with chronic lymphocytic leukemia (CLL) treated with chemoimmunotherapy. Why the survival rate of patients with unmutated IgHV is worse than that of patients with mutated IgHV is unknown. CLL cells with unmutated IgHV were thought to originate from naïve B lymphocytes, whereas CLL cells with mutated IgHV were thought to arise from B cells that have undergone somatic hypermutation (SHM). Cell surface ...

Effect of peripheral blood mononuclear cell cryopreservation on innate and adaptive immune responses.

Cryopreservation of blood-derived immune cells is commonly used in clinical trials to examine immunological responses. However, studies elucidating the effects of cryopreservation on peripheral blood mononuclear cell (PBMC) responses have shown inconsistent results making it difficult to draw meaningful conclusions. Therefore we sought to address this issue by comparing key innate and adaptive immune parameters between freshly-isolated and cryopreserved PBMCs from healthy adults. We examined the effect of c...

Functional analysis of DNA methylation of the PACSIN1 promoter in pig peripheral blood mononuclear cells.

DNA methylation plays essential roles in regulating the activity of genes and may contribute to understanding the potential epigenetic biomarkers response to viruses. To explore the function of DNA methylation of protein kinase C and casein kinase substrate in neurons 1 (PACSNI1) promoter, herein we performed the bisulfite sequencing polymerase chain reaction and Western blot analysis to verify hypermethylation and downregulation of PACSIN1 expression in peripheral blood mononuclear cells of pig as the vitr...

Associations between chronic caregiving stress and T cell markers implicated in immunosenescence.

Chronic psychological stress is associated with accelerated biological aging, immune dysfunction, and premature morbidity and mortality. Changes in the relative proportions of T cell subpopulations are thought to be a characteristic of immunological aging; however, understanding of whether these changes are associated with chronic psychological stress is incomplete. This study investigated associations between chronic caregiving stress and distributions of T cell phenotypes in a sample of high stress mother...

Circulating Levels of IL-35 and Gene Expression of FoxP3 in Coronary Artery Disease: Is There Any Interplay Between Them and 25-Hydroxyvitamin D3?

We aimed to evaluate interleukin-35 (IL-35) serum levels and the forkhead box P3 (FoxP3) expression in peripheral blood mononuclear cells (PBMCs) of coronary artery disease (CAD) patients compared with the non-CAD group. Also, we examined the possible relationship between gene expression of FoxP3 and serum levels of IL-35 with several CAD-related clinical parameters.

Interleukin-33 Gene expression and rs1342326 Polymorphism in Behçet's Disease.

Behçet's disease (BD) is a chronic multi-factorial inflammatory disease with the important role of genetic in activation of its inflammatory response. Interleukin (IL)-33 is a member of the IL-1 family of cytokines that affects innate and adaptive immune systems to promote inflammatory responses. In the current study, we investigated the association of IL-33 gene rs1342326 polymorphism and expression levels of this gene in peripheral blood mononuclear cells (PBMCs) with the susceptibility to BD in Azari po...

A cluster robustness score for identifying cell subpopulations in single cell gene expression datasets from heterogeneous tissues and tumors.

A major aim of single cell biology is to identify important cell types such as stem cells in heterogeneous tissues and tumors. This is typically done by isolating hundreds of individual cells and measuring expression levels of multiple genes simultaneously from each cell. Then, clustering algorithms are used to group together similar single-cell expression profiles into clusters, each representing a distinct cell type. However, many of these clusters result from overfitting, meaning that rather than represe...

CD90 determined two subpopulations of glioma-associated mesenchymal stem cells with different roles in tumour progression.

Human glioma-associated mesenchymal stem cells (gbMSCs) are the stromal cell components that contribute to the tumourigenesis of malignant gliomas. Recent studies have shown that gbMSCs consist of two distinct subpopulations (CD90 and CD90 gbMSCs). However, the different roles in glioma progression have not been expounded. In this study, we found that the different roles of gbMSCs in glioma progression were associated with CD90 expression. CD90 gbMSCs significantly drove glioma progression mainly by increas...

Hypermethylation of IL-10 gene is responsible for its low mRNA expression in Behçet's disease.

Interleukin-10 (IL-10), produced generally by monocyte, T helper type 2 (Th2), and regulatory T cells (Treg), plays a central role in controlling inflammatory responses and regulating the immune response of the IL-10 mRNA expression. It is significantly down-regulated in many autoimmune diseases such as Behçet's disease; this is mostly associated with more aggressive complications. Nevertheless, the essential molecular process for its low expression has not been completely realized. The aim of this project...

Focal adhesion kinase (FAK) deficiency in mononuclear phagocytes alters murine breast tumor progression.

While it has long been recognized that mononuclear phagocytes play a significant role in determining breast tumor progression, the molecular factors that contribute to these events are not fully understood. In this report, we sought to determine whether focal adhesion kinase (FAK) expression in this cell population influences primary breast tumor initiation and growth. Using the MMTV-polyoma middle T (PyVmT) murine model of spontaneous breast cancer, we found that FAK expression in mononuclear phagocytes ac...

Adaptive changes in global gene expression profile of lung carcinoma A549 cells acutely exposed to distinct types of AhR ligands.

Exposure to persistent ligands of aryl hydrocarbon receptor (AhR) has been found to cause lung cancer in experimental animals, and lung adenocarcinomas are often associated with enhanced AhR expression and aberrant AhR activation. In order to better understand the action of toxic AhR ligands in lung epithelial cells, we performed global gene expression profiling and analyze TCDD-induced changes in A549 transcriptome, both sensitive and non-sensitive to CH223191 co-treatment. Comparison of our data with resu...
