Morusin induces GSDME-dependent pyroptosis in non-small cell lung cancer via the angiotensin II receptor type 2

ABSTRACT: Lung cancer remains the leading cause of cancer-related mortality worldwide, its 5-year survival rate continues to be unsatisfactory. Current therapies are often limited by resistance, toxicity, or poor efficacy, highlighting the urgent need for novel strategies. Here, we performed a high-throughput screen for compounds and identified that morusin could activate gasdermin E (GSDME), which is expressed in non-small-cell lung cancer. Using a genome-wide CRISPR/Cas9 screen, we identified AGTR2 as a critical regulator of morusin-induced pyroptosis, which acts via activation of the caspase-3–GSDME signaling cascade. In mouse tumor models, pyroptosis induced by morusin suppresses tumor growth without cause weight loss. Thus, our study uncovers a novel mechanism through which morusin exerts its anti-tumor effect, thereby establishing AGTR2 as a potential therapeutic target and providing a rationale for pyroptosis-based non-small-cell lung cancer therapy.

Revealing disulfide bond formation in GSDME upon UVC irradiation under non-reducing conditions

Project description:It is widely acknowledged that gasdermin family proteins, which are known as the executors of pyroptosis, undergo protease-mediated cleavage prior to inducing pyroptosis. Here, we unexpectedly discovered a non-canonical form of pyroptosis mediated by full-length GSDME (FL-GSDME) without any proteolytic cleavage. Upon intense ultraviolet (UV) irradiation-triggered DNA damage, hyperactivation of nuclear PARP1 led to extensive formation of poly(ADP-ribose) (PAR) polymers and then release to the cytoplasm.These PAR polymers activate PARP5 to catalyze GSDME PARylation, resulted in a conformational change in GSDME that relieved autoinhibition imposed by its C terminus on the N terminus. On the other hand, intense UV irradiation boosted mitochondrial fission-dependent generation of mitochondrial reactive oxygen species (mito-ROS), further promoting cytochrome c-catalyzed peroxidation of cardiolipin. This lipid-ROS signal was then sensed by PARylated-GSDME and then induced oxidative oligomerization of GSDME, which facilitated FL-GSDME plasma membrane targeting for perforation, eventually inducing pyroptosis. Reagents that concurrently stimulate PARPs activity and lipid-ROS also induced sequential modifications i.e., PARylation and oxidation of FL-GSDME and synergistically promoted pyroptotic cell death. Overall, our findings elucidate a novel mechanism underlying cleavage-independent function of GSDME in executing cell demise, further enriching the paradigms and cognition of FL-GSDME-mediated non-canonical pyroptosis.

A novel non-nad-based PARP1 inhibitor, Japoflavone B, triggered Caspase-3/GSDME-mediated pyroptosis through ROS/p38/p53 pathway in NSCLC

Project description:It’s an effective anti-cancer strategy to study natual products for activating GSDME-mediated pyroptosis through targeting PARP-1 in NSCLC. Previously, we found that a novel flavonoid Japoflavone B (JFB) has exhibited an excellent inhibitory activity against cancer cell proliferation in vitro study, but its in vivo and mechanism study are still unknown. Herein, JFB could specifically inhibit the proliferation of NSCLC cells, but not normal lung epithelial cells. JFB induced inflammatory pyroptosis through the activation of caspase-3 and GSDME cleavage. JFB also activated caspase-3/7/9 activities and triggered mitochondria-mediated apoptosis. Its inhibitory activity would be significantly reversed with the caspase-3 or GSDME deficiencies and their specific inhibitors. JFB could targetedly inhibit PARP-1 activity, and promote DNA damage and ROS accumulation. Meanwhile, JFB could significantly promote p-p38 and p53 expression. Then, JFB induced cell cycle G2/M arrest by reprogramming the expression of cyclins, CDKs and CKIs. Moreover, its cytotoxicity could be dramatically reversed with the ROS scavenger and p38 inhibitor. In vivo, JFB exhibited a comparable anti-tumor activity to that of Dox with no significant tissue toxicity. Our data firstly revealed that JFB functions as a selective and non-NAD-based PARP inhibitor with high affinity and low toxicology, which makes it potential to develop as a lead anti-cancer compound. As well, JFB promoted caspase-3/GSDME-mediated pyroptosis through ROS/p38/p53 pathway in NSCLC cells. Our study was further enriched the specific mechanism that PARP inhibitor could trigger caspase-3/GSDME-mediated pyroptosis through ROS/p38/p53 pathway in NSCLC cells.

GSDME-controlled pyroptosis promotes muscle repair by coordinating tissue resident macrophages and fibro-adipogenic progenitors

Project description:GSDME (Gasdermin E) is a critical protein known for its role in pyroptosis, a form of programmed cell death associated with inflammation. We demonstrated that GSDME as a crucial mediator in muscle repair, particularly in the context of muscle damage induced by cardiotoxin (CTX). Specifically, we found that GSDME-controlled pyroptosis promotes muscle repair by coordinating the activities of tissue-resident macrophages and fibro-adipogenic progenitors (FAPs).

Corilagin Induces Pyroptosis in AML Cells by Activating the TXNIP-Caspase-3-GSDME Pathway

Project description:Acute myeloid leukemia (AML) is a challenging hematological malignancy characterized by high relapse rates and limited treatment options. Compound corilagin, an ellagitannin derived from ethnopharmacological plants, shows promise as an anti-cancer agent, although its anti-leukemic effects remain poorly understood. This study aims to investigate whether corilagin induces cell death in AML cells and explore the underlying mechanisms. In AML cells, corilagin induces pyroptosis, as characterized by the formation of pyroptotic bubbles, increased lactate dehydrogenase (LDH) release and a higher proportion of propidium iodide (PI)-positive cells. Corilagin activates caspase-3, which in turn cleaves gasdermin E (GSDME) to generate GSDME-NT, promoting pyroptosis. Additionally, corilagin activates thioredoxin-interacting protein (TXNIP), and the knockdown of TXNIP rescues cells from corilagin-induced pyroptosis. Corilagin reduces cell viability and induces pyroptosis in primary AML cells, and in an AML cell-derived xenograft (CDX) mouse model, it inhibits leukemia progression and prolongs survival. These findings imply that corilagin induces pyroptosis in AML through the TXNIP/caspase-3/GSDME pathway, presenting a prospective novel therapeutic strategy for AML treatment.

The collaboration of GSDMD and GSDME in folic acid (FA)-induced renal injury

Project description:Acute kidney injury(AKI) is associated with an increased risk of chronic kidney disease(CKD). There is still a lack of effective prevention for AKI-CKD transition. In the present study, we simultaneously explored the contribution of GSDMD and GSDME in folic acid (FA)-induced nephropathy, a model mimicking the essential components of the AKI-CKD transition. We found that blockage of both GSDMD and GSDME-mediated pyroptosis could have accumulative protection against FA-induced AKI-CKD transition. GSDME-mediated pyroptosis played a crucial role in tubular cell damage. GSDMD could exert important functions in infiltration of inflammatory cells and NETs formation. Pyroptotic tubular cells triggered NETs generation and macrophage polarization. NETs promoted macrophage-to-myofibroblast transition. Our results illustrated the orchestration of GSDMD and GSDME in AKI-CKD transition, providing new insights into the molecular mechanism for the clinical dilemma.

In situ delivery of mRNA-encoded Gasdermin E promotes antitumor immunity via creatine-elicited type Ⅰ interferon signaling in monocytes

Project description:Tumor microenvironment is highly immunosuppressive. Tumor immunotherapy aims to reverse the immunosuppressive tumor microenvironment, activating antitumor immune response, which becomes a hotspot in tumor therapy. mRNA lipid nanoparticle based gene therapy represents a promising strategy for tumor immunotherapy. Identifying novel mRNA target is critical for improving the effect of in vivo gene immunotherapy for cancer. Pyroptosis obtains the key characteristics of immunologic cell death, and GSDME is an essential effector molecule triggering pyroptosis. Here, we synthetized mRNA encoding GSDME encapsulated by LNP (LNP-Gsdme). In situ delivery of LNP-Gsdme through intratumoral injection suppressed tumor growth, boosting monocytes infiltration and CD8+ T cell activation. Mechanistically, LNP-Gsdme-induced pyroptosis and immunogenic cell death in tumor cells, releasing creatine as a novel metabolic damage associated molecular pattern as well as a metabolite biomarker of ICD, eliciting cGAMP-STING-TBK1-IRF3-IFN-I signaling pathway in monocytes, then activating CD8+ T cells in the tumor microenvironment. Furthermore, creatine synergized the antitumor efficacy of LNP-Gsdme. Our observations in this study elucidate the effect and mechanisms of LNP-Gsdme in reshaping tumor immune microenvironment, providing novel insights and therapeutic approach into cancer therapy.

Targeting PARK7: Sodium 4-Phenylbutyrate Shields Endothelial Cells from GSDME-Mediated Pyroptosis in Acute Lung Injury

Project description:Summary Sodium 4-phenylbutyrate (Na-PBA), a histone deacetylase inhibitor, shows potential in mitigating acute lung injury (ALI) by addressing endothelial cell injury. In a lipopolysaccharide (LPS)-induced ALI mouse model, Na-PBA pretreatment reduced lung damage, pulmonary edema, and inflammatory markers, while decreasing oxidative stress and endothelial pyroptosis via the cytochrome c-caspase9-caspase3-GSDME pathway. In vitro studies with human umbilical vein endothelial cells (HUVECs) confirmed that Na-PBA enhanced PARK7 expression, which is crucial for its protective effects against oxidative damage and pyroptosis. The mechanism involves PARK7 stabilizing mitochondria and inhibiting cytochrome c leakage, leading to reduced caspase activation. Na-PBA's effects are mediated through upregulation of PARK7, potentially within a positive feedback loop involving NRF2. These findings identify a novel therapeutic strategy to alleviate endothelial injury in lung diseases.
