Lyu D, Wang M, Qiu L, Deng R, Hu S, Zhang Y. Deletion of Nrf1α exacerbates oxidative stress-induced cellular senescence by disrupting cell homeostasis. BIOCHIMICA ET BIOPHYSICA ACTA. MOLECULAR CELL RESEARCH 2025; 1872:119970. [PMID: 40280334 DOI: 10.1016/j.bbamcr.2025.119970] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/12/2024] [Revised: 04/07/2025] [Accepted: 04/22/2025] [Indexed: 04/29/2025]
Abstract
Cellular senescence is recognized as a fundamental hallmark contributing to ageing and various age-related diseases, with oxidative stress playing a critical initiating role in their pathological processes. However, the anti-senescence potential of the antioxidant nuclear factor erythroid-derived 2-like 1 (Nrf1, encoded by Nfe2l1) remains elusive, despite accumulating evidence demonstrating its role as an indispensable redox-determining transcription factor for maintaining cellular homeostasis and organ integrity. This study reveals that deletion of Nrf1α significantly elevates senescence characteristics in Nrf1α-/--deficient cells, as evidenced by two distinct experimental models. These cells exhibit heightened activity of senescence-associated β-galactosidase and progressive senescence-associated secretory phenotype (SASP), accompanied by decreased cell vitality and intensified cell cycle arrest. Further investigation uncovers that this acceleration of oxidative stress-induced senescence results from increased disturbance in cellular homeostasis. The Nrf1α-/- deficiency leads to STAG2- and SMC3-dependent chromosomal stability disruption and autophagy dysfunction, albeit being accompanied by excessive accumulation of Nrf2 (encoded by Nfe2l2). The aberrantly hyperactive Nrf2 cannot effectively counteract the escalating disturbance of cellular homeostasis caused by Nrf1α-/-. This study provides evidence supporting Nrf1α's essential cytoprotective function against stress-induced cellular senescence, highlighting its indispensable contribution to maintaining robust cell homeostasis during the senescence pathophysiological process.

Plant-derived terpenoids modulating cancer cell metabolism and cross-linked signaling pathways: an updated reviews. NAUNYN-SCHMIEDEBERG'S ARCHIVES OF PHARMACOLOGY 2025:10.1007/s00210-025-03937-y. [PMID: 40019530 DOI: 10.1007/s00210-025-03937-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/18/2025] [Accepted: 02/16/2025] [Indexed: 03/01/2025]
Abstract
Cancer is a critical health issue that remains a predominant cause of mortality globally. It is a complex disease that may effectively regulate many signaling pathways and modify the metabolism of the body to evade the immune system. Understanding neoplastic metabolic reprogramming as a hallmark of cancer has facilitated the creation of innovative metabolism-targeted treatment strategies. Various signaling cascades, such as the PI3K/Akt/mTOR, ERK, JAK/STAT, MAPK/p38, NF-κB/Nrf2, and apoptotic pathways, are commonly involved in this process. It is now widely recognized that an inadequate response and the subsequent development of resistance are frequently caused by the highly selective blockage of these pathways in tumor cells. Consequently, to enhance the overall efficacy of anticancer agents, it is crucial to employ multi-target compounds that can concurrently inhibit multiple vital processes within tumor cells. The utilization of plant-derived bioactive compounds for this purpose is particularly promising, owing to their varied structures and numerous targets. Among these bioactive compounds, terpenoids have exhibited significant anticancer efficacy by targeting various altered signaling pathways. Thus, this review examines the terpenoid class of plant-derived compounds exhibiting potential anticancer activity, including their impact on metabolism and interconnected deregulated signaling pathways in human tumor cells. Accordingly, current research will help in the rational design and critical evaluation of innovative anticancer therapeutics utilizing plant-derived terpenoids for the modulation of cross-linked signaling pathways of cancer metabolism.

Cell enlargement modulated by GATA4 and YAP instructs the senescence-associated secretory phenotype. Nat Commun 2025; 16:1696.

Abstract
Dynamic changes in cell size are associated with development and pathological conditions, including aging. Although cell enlargement is a prominent morphological feature of cellular senescence, its functional implications are unknown; moreover, how senescent cells maintain their enlargement state is less understood. Here we show that an extensive remodeling of actin cytoskeleton is necessary for establishing senescence-associated cell enlargement and pro-inflammatory senescence-associated secretory phenotype (SASP). This remodeling is attributed to a balancing act between the SASP regulator GATA4 and the mechanosensor YAP on the expression of the Rho family of GTPase RHOU. Genetic or pharmacological interventions that reduce cell enlargement attenuate SASP with minimal effect on senescence growth arrest. Mechanistically, actin cytoskeleton remodeling couples cell enlargement to the nuclear localization of GATA4 and NF-κB via the Linker of Nucleoskeleton and Cytoskeleton (LINC) complex. RhoU protein accumulates in mouse adipose tissue under senescence-inducing conditions. Furthermore, RHOU expression correlates with SASP expression in adipose tissue during human aging. Thus, our study highlights an unexpected instructive role of cell enlargement in modulating the SASP and reveals a mechanical branch in the senescence regulatory network.

Abstract
Background: Cellular senescence is a state of irreversible cell cycle arrest that serves as a critical regulator of tissue homeostasis, aging, and disease. While transient senescence contributes to development, wound healing, and tumor suppression, chronic senescence drives inflammation, tissue dysfunction, and age-related pathologies, including cataracts. Lens epithelial cells (LECs), essential for maintaining lens transparency, are particularly vulnerable to oxidative stress-induced senescence, which accelerates lens aging and cataract formation. This review examines the dual role of senescence in LEC function and its implications for age-related cataractogenesis, alongside emerging senotherapeutic interventions. Methods: This review synthesizes findings on the molecular mechanisms of senescence, focusing on oxidative stress, mitochondrial dysfunction, and the senescence-associated secretory phenotype (SASP). It explores evidence linking LEC senescence to cataract formation, highlighting key studies on stress responses, DNA damage, and antioxidant defense. Recent advances in senotherapeutics, including senolytics and senomorphics, are analyzed for their potential to mitigate LEC senescence and delay cataract progression. Conclusions: LEC senescence is driven by oxidative damage, mitochondrial dysfunction, and impaired redox homeostasis. These factors activate senescence path-ways, including p53/p21 and p16/Rb, resulting in cell cycle arrest and SASP-mediated inflammation. The accumulation of senescent LECs reduces regenerative capacity, disrupts lens homeostasis, and contributes to cataractogenesis. Emerging senotherapeutics, such as dasatinib, quercetin, and metformin, show promise in reducing the senescent cell burden and modulating the SASP to preserve lens transparency.

Abstract
The cellular proteome determines the functional state of cells and is often skewed to direct pathological conditions. Autophagy shapes cellular proteomes primarily through lysosomal degradation of either damaged or unnecessary proteins. Here, we show that autophagy directs the senescence-specific translatome to fuel inflammation by coupling selective protein degradation with alternative splicing. RNA splicing is significantly altered during senescence, some of which surprisingly depend on autophagy, including exon 5 skipping of the translation regulator EIF4H. Systematic translatome profiling indicates that this event is key to the translational bias toward inflammation in senescence. Autophagy promotes these changes by selectively degrading the splicing regulator splicing factor proline and glutamine rich (SFPQ) via the autophagy receptor NBR1. These autophagy-centric inflammatory controls appear to be conserved during human tissue aging and cancer. Our work highlights the role of autophagy in the on-demand functional remodeling of cellular proteomes as well as the crosstalk between autophagy, alternative splicing, and inflammatory translation.

Abstract
Cancer cells display an altered metabolic phenotype, characterised by increased glycolysis and lactate production, even in the presence of sufficient oxygen - a phenomenon known as the Warburg effect. This metabolic reprogramming is a crucial adaptation that enables cancer cells to meet their elevated energy and biosynthetic demands. Importantly, the tumor microenvironment plays a pivotal role in shaping and sustaining this metabolic shift in cancer cells. This review explores the intricate relationship between the tumor microenvironment and the Warburg effect, highlighting how communication within this niche regulates cancer cell metabolism and impacts tumor progression and therapeutic resistance. We discuss the potential of targeting the Warburg effect as a promising therapeutic strategy, with the aim of disrupting the metabolic advantage of cancer cells and enhancing our understanding of this complex interplay within the tumor microenvironment.

Abstract
Cancer cells undergo significant metabolic reprogramming to support their rapid growth and survival. This study examines important metabolic pathways like glycolysis, oxidative phosphorylation, glutaminolysis, and lipid metabolism, focusing on how they are regulated and their contributions to the development of tumors. The interplay between oncogenes, tumor suppressors, epigenetic modifications, and the tumor microenvironment in modulating these pathways is examined. Furthermore, we discuss the therapeutic potential of targeting cancer metabolism, presenting inhibitors of glycolysis, glutaminolysis, the TCA cycle, fatty acid oxidation, LDH, and glucose transport, alongside emerging strategies targeting oxidative phosphorylation and lipid synthesis. Despite the promise, challenges such as metabolic plasticity and the need for combination therapies and robust biomarkers persist, underscoring the necessity for continued research in this dynamic field.

Abstract
Cellular immortalization is a complex process that requires multiple genetic alterations to overcome restricting barriers, including senescence. Not surprisingly, many of these alterations are associated with cancer; two tumor suppressor pathways, the cellular tumor antigen p53 and p16-Retinoblastoma (RB) pathways, are the best-characterized examples, but their mutations alone are known to be insufficient to drive full immortalization. En et al. identified a role for the lamin B receptor (LBR) in promoting cellular proliferation and immortalization in p53- and RB-deficient cells by maintaining their genome integrity and suppressing senescence. Thus, modulation of LBR could be exploited to treat cancer and potentially also to promote cell rejuvenation.

Fusobacterium periodonticum BCT protein targeting glucose metabolism to promote the epithelial-mesenchymal transition of esophageal cancer cells by lactic acid. J Transl Med 2024; 22:401.

Abstract
BACKGROUND The cancer microbiota was considered the main risk factor for cancer progression. We had proved that Fusobacterium periodonticum (F.p) was higher abundance in Esophageal cancer(EC)tissues. Bioinformation analysis found that BCT was a key virulence protein of F.p. However, little is known about the role and mechanism of BCT in EC. This study aimed to recognize the key virulence protein of F.p and explore the mechanism of BCT in promoting EC. METHODS We constructed a eukaryotic expression vector and purified the recombinant protein BCT. CCK8 used to analyzed the activity of EC after treated by different concentration of BCT. UPLC-MS/MS and ELISA used to detect the metabonomics and metabolites. The ability of migration and invasion was completed by transwell assay. RT-QPCR, WB used to analyze the expression of relevant genes. RESULTS Our data showed that BCT was higher expression in EC tumor tissues (p < 0.05) and BCT in 20 µg/mL promoted the survival, invasion and migration of EC cells (EC109) (p < 0.05). Meanwhile, UPLC-MS/MS results suggested that BCT resulted in an augmentation of hypotaurine metabolism, arachidonic acid metabolism, glycolysis/gluconeogenesis, tryptophan metabolism, citrate cycle activity in EC109. The metabolic changes resulted in decreasing in glucose and pyruvate levels but increase in lactate dehydrogenase (LDH) activity and lactic acid (LA) as well as the expression of glucose transporter 1, Hexokinase 2, LDH which regulated the glycolysis were all changed (p < 0.05). The BCT treatment upregulated the expression of TLR4, Akt, HIF-1α (p < 0.05) which regulated the production of LA. Furthermore, LA stimulation promoted the expression of GPR81, Wnt, and β-catenin (p < 0.05), thereby inducing EMT and metastasis in EC109 cells. CONCLUSION Altogether, these findings identified that impact of BCT in regulation of glycolysis in EC109 and its involves the TLR4/Akt/HIF-1α pathway. Meanwhile, glycolysis increasing the release of LA and promote the EMT of EC109 by GPR81/Wnt/β-catenin signaling pathway. In summary, our findings underscore the potential of targeting BCT as an innovative strategy to mitigate the development of EC.
