Gene expression profiling after stimulation of THP-1 cells with a2NTD

ABSTRACT: Background: Identifying the immune components that are regulated by a2NTD, a peptide cleaved from the N-terminus of the a2 vacuolar ATPase. Methods: In this study, we used pathway-focused PCR arrays to determine the genes that are regulated in human monocytic cell line, THP-1 after a2NTD stimulation over time. Results: a2NTD up-regulated several cytokines including IL-1 alpha, IL-1 beta, and IL-10. Several chemokines were also upregulated including the MCP and MIP families. Conclusion: We believe a2NTD to be an immune modulator made by tumor cells that aid in preventing immune surveillance by up-regulating proteins in monocytes that are both pro-and anti-inflammatory in nature. The Human Inflammatory Response and Autoimmunity RTM-BM-2 ProfilerM-bM-^DM-" PCR Array profiles the expression of 84 key genes involved in autoimmune and inflammatory immune responses. It represents the expression of inflammatory cytokines and chemokines as well as their receptors. It also contains genes related to the metabolism of cytokines and involved in cytokine-cytokine receptor interactions. Thoroughly researched panels of genes involved in the acute-phase response, inflammatory response, and humoral immune responses are represented as well. Using real-time PCR, you can easily and reliably analyze expression of a focused panel of genes related to inflammatory and autoimmune responses with this array.

Tumor-associated a2 vacuolar ATPase acts as a key mediator of cancer-related inflammation by inducing pro-tumorigenic properties in monocytes.

Cancer-related inflammation profoundly affects tumor progression. Tumor-associated macrophages (TAMs) are known regulators of that inflammation, but the factors that initiate cancer-related inflammation are poorly understood. Tumor invasiveness and poor clinical outcome are linked to increased expression of cell surface-associated vacuolar adenosine triphosphatases. The a2 isoform vacuolar adenosine triphosphatase is found on the surface on many solid tumors, and we have identified a peptide cle ...[more]

Project description:The innate immune response of mucosal epithelial cells during pathogen invasion plays a central role in immune regulation in the gut. Toxoplasma gondii (T. gondii) is a protozoan intracellular parasite that is usually transmitted through oral infection. Although much of the information on immunity to T. gondii has come from intra-peritoneal infection models, more recent studies have revealed the importance of studying immunity following infection through the natural per-oral route. Oral infection studies have identified many of the key players in the intestinal response; however, they have relied on responses detected days to weeks following infection. Much less is known about how the gut epithelial layer senses and reacts during initial contact with the pathogen. Given the importance of epithelial cells during pathogen invasion, this study uses an in vitro approach to isolate the key players and examine the early response of intestinal epithelial cells during infection by T. gondii. We show that human intestinal epithelial cells infected with T. gondii elicit rapid MAPK phosphorylation, NF-ÎºB nuclear translocation, and secretion of interleukin (IL)-8. Both ERK1/2 activation and IL-8 secretion responses were shown to be MyD88 dependent and TLR2 was identified to be involved in the recognition of the parasite regardless of the parasite genotype. Furthermore, we were able to identify additional T. gondii-regulated genes in the infected cells using a pathway-focused array. Together, our findings suggest that intestinal epithelial cells were able to recognize T. gondii during infection, and the outcome is important for modulating intestinal immune responses. Oral infection studies have demonstrated an increase in several cytokines and chemokines in response to T.gondii infection; however, the mixed population of the intestinal mucosa did not allow for the determination of the relative role that specific cell populations play in the production of these mediators. To address the role of intestinal epithelial cells to modulate the cytokine environment early following infection, we used specific pathway arrays to identify cytokines and chemokines induced 4 hours after exposure to T. gondii. At this time point most cells have become infected, but the parasites have not replicated.

Project description:Effects of the matricellular protein CCN1 on macrophage inflammatory gene expression was tested in a macrophage cell line I-13.35. CCN1 (CYR61) is a matricellular protein that is highly expressed at sites of inflammation and wound repair. In these contexts, CCN1 can modify the activities of specific cytokines, enabling TNF-alpha to be cytotoxic without blocking NFkB activity and enhancing the apoptotic activity of FasL and TRAIL. Here we show that CCN1 supports the adhesion of macrophages through integrin alphaMbeta2 and syndecan-4, activates NFkB-mediated transcription, and induces a pro-inflammatory genetic program characteristic of classically activated M1 macrophages that participates in Th1 responses. The effects of CCN1 include upregulation of cytokines (TNFa, IL-1a, IL-1b, IL-6, IL-12b), chemokines (MIP-1a, MCP-3, Gro1, Gro2, IP-10), regulators of oxidative stress and complement (iNOS, C3), and downregulation of specific receptors (TLR4, IL-10rb) and anti-inflammatory factors (TGF-b1). CCN1 regulates this genetic program through at least two distinct mechanisms: an immediate-early response resulting from direct activation of NFkB by CCN1, leading to the synthesis of cytokines including TNFa and IP-10; and a delayed response resulting from CCN1-induced TNFa, which acts as an autocrine/paracrine mediator to activate the expression of other cytokines including IL-1b and IL-6. These results identify CCN1 as a novel component of the extracellular matrix that activates pro-inflammatory genes in macrophages, implicating its role in regulating macrophage function during inflammation. Macrophage cell line I-13.35 (from Tlr4-defective C3H/HeJ) was treated with purified recombinant CCN1 protein for 6 hr. Total RNA was isolated, converted to cRNA probes, and hybridized to a oligonucleotide array representing 113 murine inflammation-related genes (from SA Biosciences at www.sabiosciences.com, Cat. Number OMM-011.) The array is a nylon membrane based DNA microarray on which 60-mer oligonucleotides probes were printed. Gene expression profile of resting cells incubated in serum-free medium (containing albumin, BSA) was used as a control for basal levels of gene expression.
