RIPK1 kinase-dependent gene expression in mouse microglia and astrocytes in vivo during EAE

ABSTRACT: To determine the role of RIPK1 kinase signaling in microglia and astrocytes during EAE (mouse model of MS), we extracted spinal cords of naive, EAE-vehicle and EAE mice treated with RIPK1 kinase inhibitor (GSK’547) for transcript profiling using RNAseq. We identify various genes that are differentially expressed in EAE disease compared to naive mice, and a subset of these are modulated in a RIPK1 kinase-dependent manner in both astrocytes and microglia. The top RIPK1 kinase-dependent gene pathways include oxidative phosphorylation and mitochondrial dysfunction in microglia and EIF2 signaling and cholesterol biosynthesis in astrocytes. This study demonstractes critical and distinct roles for RIPK1 kinase signaling in both microglia and astrocytes during EAE

RIPK1 kinase-dependent gene expression in mouse microglia and astrocytes in vitro

Project description:To determine the role of RIPK1 kinase-dependent transcriptional signaling in microglia and astrocytes, we stimulated cells with RIPK1 kinase-activating stimuli TNF/5z-7 and TNF/Smac/zVAD in the presence or absence of the RIPK1 kinase inhibitor Nec-1s. We identified various genes modulated in a RIPK1 kinase-dependent manner with each stimulation in both microglia and astrocytes, and the main biological pathways were related to an inflammatory and immune response. We identified many cytokines and chemokines upregulated in both microglia and astrocytes upon RIPK1 kinase activation, demonstrating the contribution of RIPK1 kinase signaling to pro-inflammatory responses in microglia and astrocytes

Quantitative Transcriptome Analysis of RIPK1-KO CD4 T cells

Project description:RIPK1 is a key signaling molecule controlling cell death and inflammation through both scaffold and kinase functions of RIPK1. Human RIPK1 deficiency causes immunodeficiency and inflammatory diseases. Here we analyzed the functional roles of RIPK1 in CD4 T cells.

SENP1 prevents steatohepatitis by suppressing RIPK1-driven apoptosis and inflammation

Project description:The mechanism underlying RIPK1-driven cell death and inflammation, a key process in the progression of nonalcoholic steatohepatitis, remains unclear. Here we identified SENP1, a SUMO-specific protease, as a key endogenous inhibitor of RIPK1. SENP1 is progressively reduced in proportion to NASH severity in patients. Hepatocyte-specific SENP1-knockout mice develop spontaneous NASH-related phenotypes in a RIPK1 kinase-dependent manner. We demonstrate that SENP1 deficiency sensitizes cells to RIPK1 kinase-dependent apoptosis by promoting RIPK1 activation following TNFα stimulation. Mechanistically, SENP1 deSUMOylates RIPK1 in TNF-R1 signaling complex (TNF-RSC), keeping RIPK1 in check. Loss of SENP1 leads to SUMOylation of RIPK1, which re-orchestrates TNF-RSC and modulates the ubiquitination patterns and activity of RIPK1. Notably, genetic inhibition of RIPK1 effectively reverses disease progression in hepatocyte-specific SENP1-knockout male mice with high-fat-diet-induced nonalcoholic fatty liver. We propose that deSUMOylation of RIPK1 by SENP1 provides a pathophysiologically relevant cell death-restricting checkpoint that modulates RIPK1 activation in the pathogenesis of nonalcoholic steatohepatitis.

Next Generation Sequencing to check the enrichment of RIPK1/BAF on chromatin, RIPK1-dependent chromatin state and RIPK1-dependent transcriptome during inflammatory responses.

Project description:RIPK1 is a master regulator of multiple cell death pathways, including apoptosis and necroptosis, and inflammation. Multiple RIPK1 inhibitors have been advanced into human clinical trials as new therapeutics for human inflammatory and neurodegenerative diseases, including ALS and AD. However, while the mechanism of cytosolic RIPK1 in control of cell death has been extensively investigated, how the activation of RIPK1 may promote transcription of proinflammatory cytokines is unclear as a nuclear function of RIPK1 has not been explored, nor is it clear if and how RIPK1 kinase activity may directly mediate inflammation independent of cell death. Here we show that nuclear RIPK1 is recruited by specific transcription factors and binds to the BAF complex on active enhancers and promoters marked by H3K4me1 and H3K27ac. Nuclear RIPK1 mediates the phosphorylation of SMARCC2, a key component of the BAF complex, to promote chromatin remodeling and the transcription of specific proinflammatory genes. Our results suggest that RIPK1 kinase serves a transcriptional coregulator in nucleus that can transmit extracellular stimuli to BAF complex to modulate the chromatin accessibility and directly regulate the transcription of specific genes involved in mediating inflammatory responses.

Genome wide Affymetric Microarray analysis for RIPK1 dependent inflammatory changes in Bone Marrow Derived Macrophages (BMDMs)

Project description:Gene level expression estimate using the Whole Transcript (WT) Assay approach of the Gene 1.0 ST Array System for Mouse. This assay was done to identify the RIPK1-dependent gene expression changes in mouse BMDMs. Cost-effective gene-level analysis based on whole-transcript coverage. We analyzed Bone Marrow Derived Macrophages (BMDMs) under 4 different conditions (Control, LPS, LPS/zVAD, LPS/zVAD/Nec-1) to assess inflammatory changes in RIPK1 kinase dependent manner compared to LPS, LPS/zVAD plus RIPK1 inhibitor Nec-1 and control.

A RIPK1-specific PROTAC degrader achieves potent antitumor activity by enhancing immunogeniccell death

Project description:Receptor-interacting serine/threonine-protein kinase 1 (RIPK1) functions as a critical stress sentinel that co- ordinates cell survival, inflammation, and immunogenic cell death (ICD). Although the catalytic function of RIPK1 is required to trigger cell death, its non-catalytic scaffold function mediates strong pro-survival signaling. Accordingly, cancer cells can hijack RIPK1 to block necroptosis and evade immune detection. We generated a small-molecule proteolysis-targeting chimera (PROTAC) that selectively degraded human and murine RIPK1. PROTAC-mediated depletion of RIPK1 deregulated TNFR1 and TLR3/4 signaling hubs, accentuating the output of NF-kB, MAPK, and IFN signaling. Additionally, RIPK1 degradation simultaneously promoted RIPK3 activation and necroptosis induction. We further demonstrated that RIPK1 degradation enhanced the immunostimulatory effects of radio- and immunotherapy by sensitizing cancer cells to treat- ment-induced TNF and interferons. This promoted ICD, antitumor immunity, and durable treatment responses. Consequently, targeting RIPK1 by PROTACs emerges as a promising approach to overcome radio- or immunotherapy resistance and enhance anticancer therapies.
