Zhai J, Min J, Gong M. Induction of ferroptosis by brucine suppresses gastric cancer progression through the p53-mediated SLCA711/ALOX12 axis. Heliyon 2024; 10:e33674. [PMID: 39050447 PMCID: PMC11267018 DOI: 10.1016/j.heliyon.2024.e33674] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2023] [Revised: 06/24/2024] [Accepted: 06/25/2024] [Indexed: 07/27/2024] Open
Abstract
Increasing evidence indicates important antiproliferative and anti-inflammatory roles of brucine in various diseases. However, the mechanism through which brucine causes the cell death of gastric cancer (GC) remains unclear. In the current research, we looked into whether brucine inhibits GC progression. GC cell migration and proliferation were assessed in response to brucine using Transwell, scratch, and the Cell Counting Kit-8 (CCK-8) assays. To assess the expression of proteins linked to ferroptosis, western blotting was used. An in vivo experiment was conducted to investigate if brucine decreases tumor growth. The CCK-8 experiment demonstrated that brucine reduced AGS and MKN45 cell viability in a way that was dose- and time-dependent. Brucine dramatically promoted cell death in AGS and MKN45 cells according to flow cytometry. In addition, brucine reduced AGS and MKN45 cells' ability to migrate. According to Western blot investigations, brucine elevated p53 and ALOX12 expression, while suppressing the expression of SLC7A11 in AGS and MKN45 cells. Notably, silencing p53 reversed brucine-induced ferroptotic cell death. Additionally, brucine was shown to decrease tumor weight and volume in in vivo experiments. Moreover, malondialdehyde (MDA) and Fe2+ levels decreased in response to brucine treatment. Furthermore, in tumors treated with brucine, p53 and ALOX12 expression increased, whereas SLCA711 expression decreased. In summary, we demonstrated that brucine regulates the p53/SLCA711/ALOX12 axis to cause ferroptosis in GC cells. The results of this study lend support to the idea of treating GC with brucine.

Arch Biochem Biophys 2024; 751:109842. [PMID: 38040224 DOI: 10.1016/j.abb.2023.109842] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2023] [Revised: 11/26/2023] [Accepted: 11/27/2023] [Indexed: 12/03/2023]
Abstract
Six-transmembrane epithelial antigen of the prostate 3 (STEAP3) has been reported to play a regulatory role in various types of cancers. However, its involvement in lung squamous cell carcinoma (LUSC) remains understudied. Here, we aimed to explore the biological functions and underlying mechanisms of STEAP3 in LUSC. Intersection genes associated with LUSC and ferroptosis were analyzed using the Venn method, STRING, GEPIA and UALCAN databases. The expression of STEAP3 was detected by qPCR and western blotting assay. Cell proliferation and viability were determined using the cell counting kit-8 assay and EDU staining. Oxidative stress and lipid peroxidation were measured by corresponding kits and DCFH-DA staining. Ferroptosis was evaluated by Phen Green SK and Western blot assay. The correlation between STEAP3 and EGFR was predicted by the TIMER and starBase database. Co-immunoprecipitation was conducted to verify the binding of STEAP3 and EGFR. The data demonstrated a significant upregulation of STEAP3 expression in LUSC cell lines. Silencing of STEAP3 suppressed H2170 cell viability and proliferation while promoting oxidative stress and lipid peroxidation through increased levels of MDA and ROS, as well as inhibited SOD activity. In addition, knockdown of STEAP3 induced ferroptosis through the regulation of ferroptosis-related proteins. Moreover, the binding between STEAP3 and EGFR was predicted and confirmed in LUSC. EGFR overexpression reversed the effects of STEAP3 silencing on H2170 cell viability, proliferation, oxidative stress, and ferroptosis. To summarize, the inhibition of STEAP3/EGFR may serve as a promising therapeutic target for LUSC treatment, as it can suppress LUSC proliferation and promote lipid peroxidation and ferroptosis.

Cell Commun Signal 2023; 21:356. [PMID: 38102610 PMCID: PMC10722859 DOI: 10.1186/s12964-023-01390-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2023] [Accepted: 11/08/2023] [Indexed: 12/17/2023] Open
Abstract
BACKGROUND Synaptosomal-associated protein 25 (SNAP25) exerts protective effects against postoperative cognitive dysfunction (POCD) by promoting PTEN-induced kinase 1 (PINK1)/Parkin-mediated mitophagy and repressing caspase-3/gasdermin E (GSDME)-mediated pyroptosis. However, the regulatory mechanisms of SNAP25 protein remain unclear. METHODS We employed recombinant adeno-associated virus 9 (AAV9)-hSyn to knockdown tumor necrosis factor α-induced protein 1 (TNFAIP1) or SNAP25 and investigate the role of TNFAIP1 in POCD. Cognitive performance, hippocampal injury, mitophagy, and pyroptosis were assessed. Co-immunoprecipitation (co-IP) and ubiquitination assays were conducted to elucidate the mechanisms by which TNFAIP1 stabilizes SNAP25. RESULTS Our results demonstrated that the ubiquitin ligase TNFAIP1 was upregulated in the hippocampus of mice following isoflurane (Iso) anesthesia and laparotomy. The N-terminal region (residues 1-96) of TNFAIP1 formed a conjugate with SNAP25, leading to lysine (K) 48-linked polyubiquitination of SNAP25 at K69. Silencing TNFAIP1 enhanced SH-SY5Y cell viability and conferred antioxidant, pro-mitophagy, and anti-pyroptosis properties in response to Iso and lipopolysaccharide (LPS) challenges. Conversely, TNFAIP1 overexpression reduced HT22 cell viability, increased reactive oxygen species (ROS) accumulation, impaired PINK1/Parkin-dependent mitophagy, and induced caspase-3/GSDME-dependent pyroptosis by suppressing SNAP25 expression. Neuron-specific knockdown of TNFAIP1 ameliorated POCD, restored mitophagy, and reduced pyroptosis, which was reversed by SNAP25 depletion. CONCLUSIONS In summary, our findings demonstrated that inhibiting TNFAIP1-mediated degradation of SNAP25 might be a promising therapeutic approach for mitigating postoperative cognitive decline.

Abstract
Ferroptosis, a regulated form of cellular death characterized by the iron-mediated accumulation of lipid peroxides, provides a novel avenue for delving into the intersection of cellular metabolism, oxidative stress, and disease pathology. We have witnessed a mounting fascination with ferroptosis, attributed to its pivotal roles across diverse physiological and pathological conditions including developmental processes, metabolic dynamics, oncogenic pathways, neurodegenerative cascades, and traumatic tissue injuries. By unraveling the intricate underpinnings of the molecular machinery, pivotal contributors, intricate signaling conduits, and regulatory networks governing ferroptosis, researchers aim to bridge the gap between the intricacies of this unique mode of cellular death and its multifaceted implications for health and disease. In light of the rapidly advancing landscape of ferroptosis research, we present a comprehensive review aiming at the extensive implications of ferroptosis in the origins and progress of human diseases. This review concludes with a careful analysis of potential treatment approaches carefully designed to either inhibit or promote ferroptosis. Additionally, we have succinctly summarized the potential therapeutic targets and compounds that hold promise in targeting ferroptosis within various diseases. This pivotal facet underscores the burgeoning possibilities for manipulating ferroptosis as a therapeutic strategy. In summary, this review enriched the insights of both investigators and practitioners, while fostering an elevated comprehension of ferroptosis and its latent translational utilities. By revealing the basic processes and investigating treatment possibilities, this review provides a crucial resource for scientists and medical practitioners, aiding in a deep understanding of ferroptosis and its effects in various disease situations.

Novel synergistic mechanism of 11-keto-β-boswellic acid and Z-Guggulsterone on ischemic stroke revealed by single-cell transcriptomics. Pharmacol Res 2023:106803.

Abstract
Although strides have been made, the challenge of preventing and treating ischemic stroke continues to persist globally. For thousands of years, the natural substances Frankincense and Myrrh have been employed in Chinese and Indian medicine to address cerebrovascular diseases, with the key components of 11-keto-β-boswellic acid (KBA) and Z-Guggulsterone (Z-GS) being the active agents. In this study, the synergistic effect and underlying mechanism of KBA and Z-GS on ischemic stroke were examined using single-cell transcriptomics. Fourteen cell types were identified in KBA-Z-GS-treated ischemic penumbra, and microglia and astrocytes account for the largest proportion. They were further re-clustered into six and seven subtypes, respectively. GSVA analysis reflected the distinct roles of each subtype. Pseudo-time trajectory indicated that Slc1a2 and Timp1 were core fate transition genes regulated by KBA-Z-GS. In addition, KBA-Z-GS synergistically regulated inflammatory reactions in microglia and cellular metabolism and ferroptosis in astrocytes. Most notably, we established an innovative drug-gene synergistic regulation pattern, and genes regulated by KBA-Z-GS were divided into four categories based on this pattern. Finally, Spp1 was demonstrated as the hub target of KBA-Z-GS. Taken together, this study reveals the synergistic mechanism of KBA and Z-GS on cerebral ischemia, and Spp1 may be the synergistic target for that. Precise drug development targeting Spp1 may offer a potential therapeutic approach for treating ischemic stroke.

[PMID: 37239365 DOI: 10.3390/genes14051005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2023] [Revised: 04/23/2023] [Accepted: 04/25/2023] [Indexed: 05/28/2023] Open
Abstract
TNF α-induced protein 1 (TNFAIP1) was first identified in human umbilical vein endothelial cells and can be induced by tumor necrosis factor α (TNFα). Early studies have found that TNFAIP1 is involved in the development of many tumors and is closely associated with the neurological disorder Alzheimer's disease. However, little is known about the expression pattern of TNFAIP1 under physiological conditions and its function during embryonic development. In this study, we used zebrafish as a model to illustrate the early developmental expression pattern of tnfaip1 and its role in early development. First, we examined the expression pattern of tnfaip1 during early zebrafish development using quantitative real-time PCR and whole mount in situ hybridization and found that tnfaip1 was highly expressed in early embryonic development and, subsequently, expression became localized to anterior embryonic structures. To investigate the function of tnfaip1 during early development, we constructed a model of a stably inherited tnfaip1 mutant using the CRISPR/Cas9 system. Tnfaip1 mutant embryos showed significant developmental delays as well as microcephaly and microphthalmia. At the same time, we found decreased expression of the neuronal marker genes tuba1b, neurod1, and ccnd1 in tnfaip1 mutants. Analysis of transcriptome sequencing data revealed altered expression of the embryonic development related genes dhx40, hspa13, tnfrsf19, nppa, lrp2b, hspb9, clul1, zbtb47a, cryba1a, and adgrg4a in the tnfaip1 mutants. These findings suggest an important role for tnfaip1 in the early development of zebrafish.
