Project description:Sensitivity to Interferon (IFN) is determined by a complex coordination of genetic and environmental factors. A previous experiment using two renal cancer cell lines differing markedly in their response to IFN were analyzed for their ISG profiles in order to determine gene expression changes associated with IFN sensitivity (Holko M, Williams BR. Functional annotation of IFN-alpha-stimulated gene expression profiles from sensitive and resistant renal cell carcinoma cell lines. J Interferon Cytokine Res 2006 Aug;26(8):534-47). Higher and more persistent expression of a subset of ISGs was noted in the IFN-sensitive RCC1 cells when compared with the relatively IFN-insensitive ACHN cells. A subset of Interferon stimulated genes (ISGs) whose sustained expression correlates with heightened IFN sensitivity were analyzed for functional and sequence similarities. This subset predominately contains genes involved in transcription, and most were found to contain in their promoters binding sites for promyleocytic zinc finger factor (PLZF), a transcriptional repressor identified by virtue of its role in the etiology of Acute Promyelocytic Leukemia (APL). Analysis of gene expression in a lymphoid cell line with inducible PLZF expression reveals that increased expression of immune system related genes including ISGs, depends on PLZF expression. Chromatin Immunoprecipitation assays show direct association between PLZF and in silico identified PLZF binding sites in ISG promoters. This study reveals a novel interaction between PLZF and IFN signaling. A time course of IFNa treatment (0, 6, 16, 24 hrs) was performed in tetetracycline induced PLZF overexpressing and control U937T:PLZF45 cells. For the 0 hr time point, PLZF overexpression (Cy5) was compared with control cells (Cy3). For the 6, 16, and 24 hr IFN treated time points, treated RNA was labelled with Cy5 and non-IFN treated RNA with Cy3. Each IFN treatment time point was performed on control and PLZF-overexpressing cells respectively.

Project description:Pegylated interferon-alpha (peg-IFNa) treatment induces molecular remissions (MR) in patients with myeloproliferative neoplasms (MPN), including partial MR (PMR) in 30-40% of patients. Here, we compared the efficacy of IFNa treatment in JAK2V617F vs. CALR-mutated cells and investigated the mechanisms of differential response. Retrospective analysis of MPN patients treated with peg-IFNa demonstrated that patients harboring the JAK2V617F mutation were more likely to achieve PMR than those with mutated CALR (p=0.004), while there was no significant difference in hematological response. In vitro experiments confirmed an upregulation of interferon-stimulated genes in JAK2V617F-positive 32D cells compared to their CALR-mutated counterparts, and higher IFNa doses were needed to achieve the same IFNa response in CALR- as in JAK2V617F mutant 32D cells.

Project description:Differentiation of naive CD8 T cells into cytotoxic effector cells requires three distinct signals- antigen (signal 1), costimulation -B7-1 (signal 2) and cytokine, either interleukin-12 or interferon-a/b (signal 3). Interaction of naive CD8 T cells with antigen and B7-1 programs cell division and proliferation whereas the presence of cytokines- IL-12 or IFNa/b promote survival, differentiation and memory establishment. In the absence of signal 3, the cells interacting with antigen/B7-1 undergo tolerance induction. The objective of this study was to elucidate the mechanisms how the provision of signal 3 promotes differentiation and averts tolerance induction in CD8 T cells. Trichostatin A is a pharmacological agent that inhibits histone deacetylase activity, hence regulating chromatin structure and gene expression and differentiation in many cell types. Gene signature profiles of IL-12, IFNa/b and trichostatin A stimulated cells were compared to elucidate the molecular mechanisms of gene regulation. Oligonucleotide microarray analysis is carried out to determine the extent and molecular nature of the CD8 T cell differentiation program induced by IL-12 or IFNa/b in concert with antigen and B7-1 signal. Experiment Overall Design: The programming for development of function and memory in presence of signal 3 occurs over three days of initial stimulation, and antigen-B7 and IL-12 or IFNa/b must be present for most of this period to achieve maximal responses. We analyzed gene expression in highly purified naive CD8 T cells at 0, 24, 48 and 72h of in vitro culture stimulated with antigen-B7 and with or without IL-12 or IFNa/b to tease apart gene expression profiles of naive, 2-signal and 3-signal stimulated cells over the course of 3-days. Gene expression of cells stimulated with trichostatin A for 72hr were compared with IL-12 or IFNa/b stimulated cells. 20 arrays.

Project description:We report the grobal gene expression in follicular (FO) B cells stimulated with CpG, IFNa, and CpG plus IFNa for 12 hours prior to the onset of PC differentiation. We found that stimulation with CpG plus IFNa upregulates metabolic processes compared to stimulation with CpG alone. This study highlight the pivotal role of IFNa in determining the fate of PC differentiation of TLR9-activated FO B cells.

Project description:We used microarrays to compare interferon-alpha (IFNa)- and interferon-gamma (IFNg)-stimulated genes under an equivalent biological input. The goal was to compare IFNa- and IFNg-stimulated genes, as well as to identify common and distinct sets of type I and II ISGs. Bone marrow macrophages derived from mouse bone marrow in M-CSF for 7 days. The cells were stimulated with 62U/mL IFNa and 1U/mL of IFNg for 2.5 hrs in culture. These concentrations induced equivalent STAT1 phosphorylation in BMMs.
