PPDPF suppresses the development of hepatocellular carcinoma through TRIM21-mediated ubiquitination of RIPK1

ABSTRACT: Our study have shown that PPDPF promoted NF-κB activation through TRIM21-mediated K63-linked ubiquitination of RIPK1 in hepatocytes. Upon TNF-α stimulation, PPDPF enhances TRIM21/RIPK1 interaction and increases TRIM21-mediated K63-linked ubiquitination of RIPK1, which promotes NF-κB activation.To map the ubiquitination site of RIPK1 regulated by PPDPF, we performed MS analysis using control and RIPK1-overexpressing HEK293T cells with or without PPDPF overexpression

Palmitoylation licenses RIPK1 cytotoxicity in the TNF pathway

Project description:We identified S-palmitoylation as a licensing modification for RIPK1 kinase activity in the TNF pathway. We found that DHHC5 palmitoylates RIPK1 at Cys257 residue, a process dependent on K63-linked ubiquitination of RIPK1, in response to TNF stimulation.

Ubiquitination profile of polarized macrophages

Project description:Previous studies linked mac activation with the ubiquitination (ub) status of key proteins in inflammatory signal pathways. Lysine-48 ub (K48-ub) of the NF-κB inhibitor (IκB), the final checkpoint of the NFκB pathway, leads to IκB degradation and consequent NF-κB-associated inflammation. In contrast, TRAF6, an upstream positive regulator of the NF-κB pathway, is modulated by K63-ub, leading to its conformational change and activation. However, a comprehensive analysis of ub profiles of polarized macs has not been reported. If a unique ub signature is associated with individual mac subsets is not known.

Cooperation of TRADD- and RIPK1-dependent Cell Death Pathways in Maintaining Intestinal Homeostasis

Project description:Dysfunctional NF-kB signaling is critically involved in Inflammatory bowel disease (IBD). We investigated the mechanism by which RIPK1 and TRADD, two key mediators of NF-kB signaling, in mediating intestinal pathology using TAK1 IEC deficient model. We show that phosphorylation of TRADD by TAK1 modulates RIPK1-dependent apoptosis. TRADD and RIPK1 act cooperatively to mediate cell death mediated by TNF and TLR signaling. We demonstrate the pathological evolution from RIPK1-dependent ileitis to RIPK1- and TRADD-co-dependent colitis in TAK1 IEC deficient condition. Combined RIPK1 inhibition and TRADD knockout completely protect against intestinal pathology and lethality in TAK1 IEC KO mice. Furthermore, we identify distinctive microbiota dysbiosis biomarkers for RIPK1-dependent ileitis and TRADD-dependent colitis. These findings reveal the cooperation between RIPK1 and TRADD in mediating cell death and inflammation in IBD with NF-kB deficiency and suggest the possibility of combined RIPK1 kinase inhibition and TRADD knockout as a new therapeutic strategy for IBD.

TNFR2 induced priming of the inflammasome leads to a RIPK1-dependent cell death in the absence of XIAP

Project description:The pediatric immune deficiency X-linked proliferative disease-2 (XLP-2) is a unique disease, with patients presenting with either hemophagocytic lymphohistiocytosis (HLH) or intestinal bowel disease (IBD). Interestingly, XLP-2 patients display high levels of IL-18 in the serum even while in stable condition, presumably through spontaneous inflammasome activation. Recent data suggests that LPS stimulation can trigger inflammasome activation through a TNFR2/TNF/TNFR1 mediated loop in xiap−/− macrophages. Yet, the direct role TNFR2-specific activation plays in the absence of XIAP is unknown. We found TNFR2-specific activation leads to cell death in xiap−/− myeloid cells, particularly in the absence of the RING domain. RIPK1 kinase activity downstream of TNFR2 resulted in a TNF/TNFR1 cell death, independent of necroptosis. TNFR2-specific activation leads to a similar inflammatory NF-kB driven transcriptional profile as TNFR1 activation with the exception of upregulation of NLRP3 and caspase-11. Activation and upregulation of the canonical inflammasome upon loss of XIAP was mediated by RIPK1 kinase activity and ROS production. While both the inhibition of RIPK1 kinase activity and ROS production reduced cell death, as well as release of IL-1β, the release of IL-18 was not reduced to basal levels. This study supports targeting TNFR2 specifically to reduce IL-18 release in XLP-2 patients and to reduce priming of the inflammasome components.

The deubiquitinase OTUD7B ameliorates central nervous system autoimmunity by inhibiting degradation of glial fibrillary acidic protein and astrocyte hyperinflammation

Project description:Astrocytes are central to the pathogenesis of multiple sclerosis; however, their regulation by intrinsic post-translational ubiquitination and deubiquitination is unresolved. This study shows that the deubiquitinating enzyme OTUD7B in astrocytes confers protection against murine experimental autoimmune encephalomyelitis, a model of MS, by limiting neuroinflammation. RNA-sequencing of isolated astrocytes and spatial transcriptomics showed that in EAE OTUD7B downregulates the expression of chemokines in astrocytes of inflammatory lesions, which is associated with reduced recruitment of encephalitogenic CD4+ T cells. Furthermore, OTUD7B was essential for GFAP protein expression of astrocytes bordering inflammatory lesions. Mechanistically, OTUD7B (i) restricted TNF-induced chemokine production of astrocytes by sequential K63- and K48-deubiquitination of RIPK1 limiting NF-κB and MAPK activation and (ii) enabled GFAP protein expression by supporting GFAP mRNA expression and preventing its proteasomal degradation through K48-deubiquitination of GFAP. This dual action on TNF signaling and GFAP identifies astrocyte-intrinsic OTUD7B as a central inhibitor of astrocyte-mediated inflammation.

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.
