Streptococcus salivarius is an early colonizer of human oral and nasopharyngeal epithelia, and strain K12 has reported probiotic effects. An emerging paradigm indicates that commensal bacteria downregulate immune responses through the action on NF-kappaB signaling pathways, but additional mechanisms underlying probiotic actions are not well understood. Our objective here was to identify host genes specifically targeted by K12 by comparing their responses with responses elicited by pathogens and ...[more]

Transcription profiling of human monocytic cell line, THP-1 cells were stimulated 4 hours with chemokine MIG or CCL2/MCP-1

Project description:The objective of the study was to discover new functions of chemokine CXCL9/MIG, a cationic chemokine that has antimicrobial properties. Human monocytic cell line, THP-1 cells were stimulated 4 hours with chemokine MIG or CCL2/MCP-1 (a chemokine that is not positively charged and has no antimicrobial activity). By using a 21,000 oligo-based DNA human microarray we analyzed gene expression profiles induced by MIG and by MCP-1. The gene expression profile induced by MIG was >85% different from that induced by MCP-1. MIG increased transcription of genes encoding various chemokines (including CCL3/MIP-1alpha, CCL4/MIP-1beta, CCL2/MCP-1 and CXCL8/IL-8), cytokines (TNF-alpha), indicating that MIG has an immunomodulatory effect on THP-1 cells. Additionally, MIG strongly up-regulated a set of genes identified as having tumor suppressor functions, including BTG2, BTG1, P21, IGFBP3, DSCR1 and genes encoding markers for mature leukocyte differentiation (PLAU, LPL, PLAUR etc). In parallel, MIG down-regulated the expression of oncogenes (MYC), and genes related to cell proliferation and cell cycle progression. This gene profile strongly suggested that the chemokine MIG had anti-proliferative activity and might induce THP-1 cells to undergo terminal differentiation.

Transcription profiling of human monocytic cells THP-1 stimulated with LPS (10ng/ml) in presence or absence of LL-37 (5 ug/ml), as well as with the peptide alone, for 4 hours

Project description:The objective of the study was to evaluate transcriptional response of endotoxin-stimulated human monocytic cells in presence or absence of host defense peptide LL-37 at low physiologically relevant concentrations. Human monocytic cells THP-1 were stimulated with LPS (10ng/ml) in presence or absence of LL-37 (5 ug/ml), as well as with the peptide alone, for 4 hours. The trends of LPS-induced altered gene expression in presence of the peptide were further validated by quantitative real-time PCR.

Transcription profiling of responses to TNF-alpha, IL-1beta, peptidoglycan or lipopolysaccharide (TLR2/4 agonists) evaluated at 4 hrs in peripheral blood monocytes (PBM) from the patient bearing the IRAK4 Q293X mutation vs PBM from 5 healthy individuals

Project description:IL-1R associated kinase-4 (IRAK4) is a key enzyme required for activation of the common Toll-like Receptor (TLR) signaling cascade, which results in the transcription of inflammatory and immunity genes. IRAK-4 deficiency has recently been described as a rare form of innate immunodeficiency. Patients present with pyogenic bacterial infections and bacteraemia, particularly with Gram+ Streptococcus pneumoniae, and isolated PBMC from these patients fail to produce inflammatory cytokines in response to TLR agonists. We embarked on this study for several purposes: (1) to identify defective gene response resulting from IRAK4-deficiency that are responsible for the patients' susceptibility to infection by particular bacteria (2) to identify genetic responses that confer relatively normal immunity in these patients despite having a defect in such a critical component of the innate immune system (3) to gain understanding of the transcriptional regulation of inflammatory genes (4) to gain insight into TLR signal transduction pathways, in particular, the role of IRAK4 in the TLR2 and TLR4 pathways initiated by Gram+ and Gram- bacterial components respectively. Transcriptional responses to TNF-alpha, IL-1beta, peptidoglycan or lipopolysaccharide (TLR2/4 agonists) were evaluated at 4 hrs in peripheral blood monocytes (PBM) from the patient bearing the IRAK4 Q293X mutation compared to PBM from 5 healthy individuals.

Transcription profiling of endotoxin-stimulated human monocytic cells in presence and absence of host defense peptide LL-37

Project description:The objective of the study was to evaluate transcriptional response of endotoxin-stimulated human monocytic cells in presence and absence of host defense peptide LL-37. A functional genomics approach was used to establish a temporal transcriptional profile and identify differentially expressed genes in LPS (100ng/ml)-stimulated human monocytic THP-1 cells, in the presence or absence of LL-37 (20ug/ml) after 1, 2, 4 and 24 hrs of stimulation. The peptide significantly inhibited the expression of LPS-induced pro-inflammatory genes regulated by NF-kappa B, such as NF-kappa B1 (p105/p50) and TNF-alpha-induced protein 2 (TNFAIP2). In contrast, LL-37 did not significantly inhibit LPS-induced genes that antagonize inflammation, such as TNF-alpha-induced protein 3 (TNFAIP3) and the NF-kappa B inhibitor, NF-kappa BIA, or genes involved in cell movement and recruitment (chemokines). The trends of gene expression were further validated by quantitative real-time PCR. This study implicates that LL-37 plays a role in the delicate balancing act of inflammatory responses.

Transcription profiling of peripheral blood monocytes from healthy humans and from those with Chronic Granulamatous Disease in response to stimulation with peptidoglycan and lipopolysaccharide

Project description:Persons with Chronic Granulomatous Disease, are susceptible to a narrow range of infections resulting from the failure of cells to generate toxic reactive oxygen species (ROS) required for phagocytice oxidative killing of microorganisms. For unknown reasons, many inflammatory conditions (inflammatory bowel disease, periodontal inflammation, granulomatous obstruction of the urinary and gastrointestinal tract and “sterile” inflammation of the lungs and other organs) are also associated with the disease. The goal of this study is to investigate the role of ROS in the regulation of inflammatory and immunity genes induced by Toll-like Receptors (TLRs). Transcriptional responses to peptidoglycan or lipopolysaccharide (TLR2/4 agonists) were evaluated at 4 and 24 hrs in peripheral blood monocytes (PBM) from three males with CGD compared to PBM from 5 healthy individuals.

Transcription profiling of human carcinoma in situs cells from testis compared to fetal gonocytes, oogonia and cultured embryonic stem cells

Project description:Abstract: Testicular cancers in young adult men derive from an inborn precursor lesion, called carcinoma in situ (CIS) of the testis. CIS cells are believed to arise from primordial germ cells or gonocytes that fail to differentiate into the male germ cell lineage, and show a remarkable resemblance to embryonic stem cells (ESC). With this study we aimed at further elucidating the origin of CIS using microarray analysis of genome-wide gene expression. CIS cells only constitute a small fraction of the tissue and therefore, to reduce contaminating RNA from other cell types, we developed a fast (160 sec) staining procedure specific for CIS and fetal germ cells. Highly enriched cell populations were obtained by laser microdissectioning. The expression profiles of CIS cells were compared to microdissected fetal gonocytes, oogonia and cultured ESC with and without genomic amplifications. The cell type most similar to CIS was the gonocytes indicating malignant transformation at this stage. The enriched cell populations allowed us to find unique expression patterns for the developmentally very related cell types. Analyses of the similarities and differences among the cell types may help us understand when and how the malignant transformation to CIS occurs.

MicroRNA profiling of human breast cancer cell line MCF7 under conditions of hypoxia

Project description:Hypoxia results in the changes in expression of many genes, the majority of which are mediated via the transcriptional activity of the hypoxia inducible factor (HIF) complex. However, other mechanisms of gene regulation by hypoxia are likely and include control of mRNA stability, regulation of mRNA translation and regulation mediated by micrornas. The aim of this study is to identify microRNAs which expression is regulated by hypoxia. We chose the breast cancer line MCF7 for study as we had previously characterised the expression of the components of the HIF system in that cell line and undertaken an extensive study of the gene expression profile in response to hypoxia, a prolyl hydroxylase inhibitor dimethyloxalylglycine and HIF-1a isoform manipulations (Eldvidge. G.P. et al. (2006) JBC, vol. 281, 22, 15215-15226).
