Project description:JAK/STAT pathway plays important roles in controlling Drosophila intestinal homeostasis and regulating the ISC proliferation and differentiation. However,the downstream targets of its transcription factor-STAT92E remain largely unknown.To further identify the regualtory mechanisms of the JAK/STAT pathway in controlling intestinal homeostasis,we performed the ChIP-Seq assay with mouse raised STAT92E antibody using JAK/STAT signaling highly activated adult intestines.Through the ChIP assay, we have identified over 1000 significant peaks (p<0.01) around the putative targets.The well-characterized JAK/STAT downstream targets including Domeless,Socs36E,STAT92E and chinmo were identified in our ChIP assay,indicating that our experiment is workable to identify novel JAK/STAT downstream targets in adult intestines.This work will provide insights into our understanding of regulatory mechanisms of JAK/STAT signaling during Drosophila intestinal development.

Project description:Immune cells need to sustain a state of constant alertness over a lifetime. Yet, little is known about the regulatory processes that control the fluent and fragile balance that is called homeostasis. Here we demonstrate that JAK-STAT signaling, beyond its role in immune responses, is a major regulator of immune cell homeostasis. We investigated JAK-STAT-mediated transcription and chromatin accessibility across 12 mouse models, including knockouts of all STAT transcription factors and of the TYK2 kinase. Baseline JAK-STAT signaling was detected in CD8+ T cells and macrophages of unperturbed mice – but abrogated in the knockouts and in unstimulated immune cells deprived of their normal tissue context. We observed diverse transcription-regulatory programs, including gene regulation by STAT2 and IRF9 independent of STAT1. In summary, our large-scale dataset and integrative analysis of JAK-STAT mutant and wildtype mice uncovered a crucial role of JAK-STAT signaling in unstimulated immune cells, where it contributes to a poised epigenetic and transcription-regulatory state and helps prepare these cells for rapid response to immune stimuli.

Project description:Although the JAK/STAT pathway regulates numerous processes in vertebrates and invertebrates through modulating transcription, its functionally-relevant transcriptional targets remain largely unknown. With one jak and one stat (stat92E), Drosophila provides a powerful system for finding new JAK/STAT target genes. Genome-wide expression profiling on eye discs in which Stat92E is hyperactivated, revealed 584 differentially-regulated genes, including known targets domeless, socs36E and wingless. Other differentially-regulated genes (chinmo, lama, Mo25, Imp-L2, Serrate, Delta) were validated and may represent new Stat92E targets. Genetic experiments revealed that Stat92E cell-autonomously represses Serrate, which encodes a Notch ligand. Loss of Stat92E led to de-repression of Serrate in the dorsal eye, resulting in ectopic Notch signaling and aberrant eye growth there. Thus, our micro-array documents a new Stat92E target gene and a previously-unidentified inhibitory action of Stat92E on Notch signaling. These data suggest that this study will be a useful resource for the identification of additional Stat92E targets. Identification of the JAK/STAT pathway target genes in the Drosophila eye disc Keywords: Genotype comparison Gene expression profiles from five biological replicates of eye discs with yw (control) and GMR-upd (overexpressing JAK/STAT ligand unpaired) were compared using genome wide mRNA expression profiling by Affymetrix genechip arrays (Drosophila 2.0) and key targets were validated by clonal analysis, in situ hybridization, immunohistochemical staining and quantitative real-time PCR.

Project description:NCBS Curation Comments:
This model shows the control mechanism of Jak-Stat pathway, here SOCS1 (Suppressor of cytokine signaling-I) was identified as the negative regulator of Jak and STAT signal transduction pathway. This is the knockout version of Jak-Stat pathway in this model the SOCS1 has been knocked out i.e it formation is not shown. The graphs are almost similar to the graphs as shown in the paper but STAT1n graph has some ambiguities. Thanks to Dr Satoshi Yamada for clarifying some of those ambiguities and providing the values used in simulations.
Biomodels Curation Comments:
The model reproduces the figures 2 (B,D,F,H,J,L,N) corresponding to JAK/STAT activation in SOCS1 knock out cells. The model was successfully tested on MathSBML

Project description:NFIC1, the longest isoform of NFIC, is essential for the regulation on spatiotemporal expressions of drug-metabolizing genes in liver. However, the role of NFIC1 in breast cancer is not clear. Here we showed that increased expression of NFIC1 suppressed the migration and invasion of MCF-7 cells. The activation of interferon-associated Jak-STAT pathway was enhanced with NFIC1 overexpression. NFIC1 overexpression upregulated the expression of IFNB1, IFNL1, IFNL2 and IFNL3. Treatment with Jak-STAT pathway inhibitors, Filgotinib or Ruxolitinib, reversed the suppressive effects of NFIC1 overexpression on migration and invasion. In addition, we found that MX1 and MX2 were the target genes of NFIC1- activated Jak-STAT pathway, which mediated the migration and invasion of MCF-7 cells. These results demonstrated that NFIC1 inhibited the migration and invasion in MCF-7 cells through interferon mediated activation of Jak-STAT pathway, indicating that Jak-STAT pathway might be a potential therapeutic target for preventing breast cancer metastasis.

Project description:Developing targeted therapy for cutaneous T cell lymphoma (CTCL) patients still requires actionable mutated genes and deregulated pathways to be identified. There is increasing evidence that activating mutations in JAK genes and deregulated JAK/STAT signaling are important mechanisms involved in multiple B and T cell malignancies, including CTCL. Therefore, in this study we focused on studying the mutational status of JAK1, JAK2 and JAK3 genes in a series of human CTCL lesions and cell lines using next-generation sequencing (NGS). We found that 7 of 48 (14.7%) of the analyzed cases harbored mutations in the JAK1 and JAK3 genes that mainly affected the pseudokinase domain of the corresponding proteins. On the basis of these results, we used a specific JAK inhibitor (INCB018424) in a series of CTCL cell lines with deregulated JAK/STAT activity. Treatment of CTCL cells with INCB018424 resulted in dose-dependent reduction of activated STAT expression, diminished cell viability, and increased apoptosis. We also studied global changes in gene expression in cells with mutated JAK1 and JAK3 proteins treated with INCB018424 and identified multiple genes that were differentially regulated by JAK/STAT signaling, such as FGF20 (upregulated) and EGR1 (downregulated). Thus, our results show that the detection of deregulated JAK/STAT signaling in CTCL lesions via JAK mutations or other surrogate markers may serve to indicate the clinical use of JAK/STAT inhibitors. 3 replicates of cells treated with DMSO or JAKi during 30 min and 3h

Project description:We performed RNA sequencing analysis of hepatic gene expression a few hours after amlexanox treatment, and identified over 1700 differentially expressed genes. Pathway analysis of these differentially regulated genes revealed that the top two most enriched pathways were the adipocytokine signaling pathway and the Jak-STAT signaling pathway. RNA-seq analysis of hepatic gene expression was used to identify differentially expressed genes in response to Amlexanox treatment.
