Project description:Overexpression of STAT5B_N642H mutant results in the ligand-independent activation of STAT5 signaling and STAT5 transcriptional activity, without affecting MAPK-ERK or PI3K-AKT signalling pathways. Overexpression of wild type (WT) STAT5B did not activate STAT5 signaling . Treatment with prednisolone boosts the expression of STAT5_N642H regulated genes, whereas NR3C1 can bind at gene loci of STAT5 regulated genes. Despite the steroid-enhanced upregulation of anti-apoptotic targets, the mutant cell line remaind sensitive to steroid treatment. We studied potential co-regulation and co-binding of NR3C1 and STAT5B in STAT5B_N642H and STAT5B_WT overexpressing cells, treated and untreated with prednisolone.

Project description:Interleukin-15 (IL-15) is essential for the development and maintenance of natural killer (NK) cells. IL-15 activates STAT5 proteins, which can form dimers or tetramers. We previously found that NK cell numbers are decreased in Stat5a-Stat5b tetramer-deficient double knockin (DKI) mice, but the mechanism was not investigated. Here we show that STAT5 dimers are sufficient for NK cell development, whereas STAT5 tetramers mediate NK cell maturation and the expression of maturation-associated genes. Unlike the defective proliferation of Stat5 DKI CD8+ T cells, Stat5 DKI NK cells have normal proliferation to IL-15 but are susceptible to death upon cytokine withdrawal, with lower Bcl2 and increased active caspases. These findings underscore the importance of STAT5 tetramers in maintaining NK cell homeostasis. Moreover, defective STAT5 tetramer formation could represent a cause of NK cell immunodeficiency, and interrupting STAT5 tetramer formation might serve to control NK leukaemia.

Project description:The NUP214-ABL1 fusion is a constitutively activated tyrosine kinase that is significantly associated with overexpression of the TLX1 or TLX3 transcription factors in T-cell acute lymphoblastic (T-ALL). Here we show that NUP214-ABL1 kinase cooperates with TLX1 in driving T-ALL development using a transgenic mouse model. Using ChIP-seq and ATAC-seq, we show that TLX1 and STAT5, the downstream effector of NUP214-ABL1, selectively increase the accessibility of enhancer regions, and cooperatively activate the expression of key proto-oncogenes such as MYC and BCL2. Moreover, MYC is also part of the TLX1/STAT5 complex and inhibition of both MYC and STAT5 leads to reduction of target gene expression.

Project description:The signal transducer and activator of transcription 5 (STAT5) is an attractive therapeutic target but successful targeting of STAT5 has proved to be difficult. We report herein the development of AK-2292 as a first, potent and selective small-molecule degrader of both STAT5A and STAT5B isoforms. AK-2292 induces degradation of STAT5A/B proteins with an outstanding selectivity over all other STAT proteins and >6,000 non-STAT proteins, leading to selective inhibition of STAT5 activity in cells. AK-2292 effectively induces STAT5 depletion in normal mouse tissues and human chronic myeloid leukemia (CML) xenograft tissues and achieves tumor regression in two CML xenograft mouse models at well-tolerated dose-schedules. AK-2292 is not only a powerful research tool with which to investigate the biology of STAT5 and therapeutic potential of selective STAT5 protein depletion and inhibition in vitro and in vivo, but also a promising lead compound toward ultimate development of a STAT5-targeted therapy.

Project description:STAT5A and STAT5B proteins belong to the family of signal transducers and activators of transcription. They are encoded by 2 separate genes with 91% identity in their amino acid sequences. Despite their high degree of conservation, STAT5A and STAT5B exert non-redundant functions, resulting at least in part from differences in target gene activation. To better characterize the differential contribution of STAT5A and STAT5B in gene regulation, we performed single or double knock-down of STAT5A and STAT5B using small interfering RNA. Subsequent gene expression profiling and RT-qPCR analyses of IL-3-stimulated Ba/F3-beta cells led to the identification of putative novel STAT5 target genes. Chromatin immunoprecipitation assays analyzing the corresponding gene loci identified unusual STAT5 binding sites compared to conventional STAT5 responsive elements. Some of the STAT5 targets identified are upregulated in several human cancers, suggesting that they might represent potential oncogenes in STAT5-associated malignancies.

Project description:STAT5 is critical for inducing lineage specifying transcription factors, establishing effector gene programs, upregulating IL-2Rα (also known as CD25), and supporting cell survival in response to environmental cues in mature T cells. Although it has been shown that IL-7-induced STAT5 signaling is also essential for survival of thymic precursor cells, the exact roles of STAT5A and STAT5B and their target genes that contribute to the developmental program in early thymic development have been unknown. To define STAT5 target genes in these early T-cell progenitors, we have performed CRISPR-Cas9 mediated acute deletion of Stat5a and Stat5b in combination. We first carried out preliminary experiments to determine the stages in which IL-7 could induce maximal STAT5 phosphorylation in thymic double negative (DN) cells (B. Shin, unpublished data). We then focused on genes responding to loss of STAT5 in two different stages: CD25+ Bcl11b- pre-commitment stage, and CD25+ Bcl11b+ post-commitment stage. Of note, to generate these early pro-T cells in OP9-DLL1 coculture, we exploited bone-marrow precursor cells expressing a Bcl2 transgene to minimize survival defects due to loss of STAT5A and STAT5B. Our data show that STAT5 is necessary, in both pre- and post-commitment stages, for optimal expression of the IL-2Rα gene (Il2ra), which is constitutively expressed in normal DN2 and DN3 pro-T cells. This dataset further defines a distinct set of additional genes responding more strongly to loss of STAT5 in pro-T cells. The linked manuscript by R. Spolski et al. and other datasets referenced therein include data documenting the genomic occupancy of STAT5B in corresponding stages. In summary, our data define STAT5-responsive target genes during early T development.

Project description:Cytokines utilize the transcription factor STAT5 to control cell-specific and universal genes. In general, the magnitude of cell-restricted gene activation greatly exceeds that of universal genes, with a mechanistic explanation yet to be supplied. Genome-wide studies have identified putative STAT5-based mammary-specific enhancers and universal STAT5-controlled regulatory elements, an opportunity to investigate mechanisms underlying their differential response to cytokines. We have now interrogated the integrity and function of both categories of regulatory elements using biological and genetic approaches. During lactation, STAT5 occupies mammary-specific and universal cytokine-responsive elements. Following lactation, prolactin levels decline and STAT5-dependent enhancers at mammary-specific genes are decommissioned with 24 hours while universal regulatory complexes remain intact. These differential sensitivities are linked to STAT5 concentrations and the mammary-specific Stat5 autoregulatory enhancer. In its absence, mammary-specific enhancers, but not universal elements, fail to be fully established. Upon termination of lactation, STAT5 binding to a subset of mammary enhancers is substituted by STAT3. No STAT3 binding was observed at the most sensitive STAT5 enhancers, suggesting that upon hormone withdrawal their chromatin becomes inaccessible. This study, for the first time, provides molecular insight into the differential sensitivities of mammary-specific and universal cytokine-sensing enhancers.

Project description:STAT5 and IL-7 signaling are thought to control B-lymphopoiesis by regulating key transcription factor genes and activating VH gene segments at the Igh locus. Using conditional mutagenesis, we demonstrate that transgenic Bcl2 expression rescued the development of Stat5-deleted pro-B cells by compensating for the loss of Mcl-1. Ebf1 and Pax5 expression as well as VH recombination were normal in Bcl2-rescued pro-B cells lacking STAT5 or IL-7Ra. In agreement with this finding, STAT5-expressing pro-B cells contained little or no active chromatin at most VH genes. In contrast, Igk rearrangements were increased in STAT5- or IL-7Ra-deficient pro-B cells, consistent with direct binding of STAT5 to the intronic iEk enhancer in wild-type pro-B cells. Hence, STAT5 and IL-7 signaling control cell survival and suppress premature Igk recombination in early B-lymphopoiesis. comparison of wt vs Rag2-/- pro-B cells
