In vivo cell ablation technologies are essential tools for understanding biological processes within living animal models. The nitroreductase (NTR)/metronidazole system enables highly effective spatiotemporal cell ablation. Using transgenic zebrafish that combine NTR2.0 with the QF3/QUAS binary gene expression system, conditions to achieve efficient cell type–specific chemogenetic ablation were optimized. This approach provides a versatile in vivo platform for investigating developmental processes and regeneration, as well as for disease modeling and drug discovery.

Viral transduction of primary T cells enables stable genetic engineering for research and immunotherapy, supporting both transgene overexpression and gene deletion. Although the overall workflow can be similar to transduction in other mammalian cell lines, primary T cell culture imposes distinct requirements such as cell-state-dependent nuances shaped by T cell activation and proliferation, which can make it challenging to obtain a sufficient number of genetically engineered T cells. This article provides practical guidance for researchers new to T cells but familiar with basic mammalian cell culture.
原代T细胞的病毒转导可以为研究和免疫治疗提供稳定的基因工程,支持转基因过表达和基因缺失。尽管整个工作流程可能与其他哺乳动物细胞系的转导相似,但原代T细胞培养施加了不同的要求,例如由T细胞激活和增殖形成的细胞状态依赖性细微差别,这使得获得足够数量的基因工程T细胞具有挑战性。本文为新接触T细胞但熟悉基本哺乳动物细胞培养的研究人员提供实用指导。

Cytokinesis, the final stage of cell division, physically partitions the cytoplasm between daughter cells through mechanisms evolved to accommodate unique cellular constraints. Plant cells divide by the formation of rigid cell walls using the phragmoplast—a specialized structure guiding centrifugal cell plate formation from the cell center outward. Despite structural differences from the animal contractile ring mechanism, plant and animal cytokinesis share fundamental similarities in division plane determination, vesicle trafficking, and conserved proteins, including kinesins and microtubule-associated proteins. This conservation alongside kingdom-specific adaptations makes plant cytokinesis an excellent model for understanding evolutionary divergence. Recent technological advances have enabled detailed characterization of molecular components and regulatory networks controlling spatiotemporal progression through post translational modifications. In this review, we provide an integrated perspective of plant cytokinesis, examining cellular dynamics from division plane determination to cell plate maturation, molecular machinery driving these processes, and kinase-mediated regulatory networks ensuring precise coordination of this complex process.
细胞质分裂是细胞分裂的最后阶段,通过进化的机制将细胞质在子细胞之间进行物理划分,以适应独特的细胞限制。植物细胞分裂的方式是利用隔膜形成坚硬的细胞壁,隔膜是一种特殊的结构,引导离心细胞板从细胞中心向外形成。尽管与动物的收缩环机制存在结构上的差异,但植物和动物的细胞分裂在分裂面确定、囊泡运输和保守蛋白(包括运动蛋白和微管相关蛋白)方面具有基本的相似性。这种保守性加上王国特有的适应性,使植物细胞分裂成为理解进化分化的一个极好的模型。最近的技术进步使得通过翻译后修饰控制时空进展的分子成分和调控网络的详细表征成为可能。在这篇综述中,我们提供了植物细胞分裂的综合视角,研究了从分裂平面决定到细胞板成熟的细胞动力学,驱动这些过程的分子机制,以及确保这一复杂过程精确协调的激酶介导的调节网络。

Aging in Caenorhabditis elegans is regulated by evolutionarily conserved pathways that coordinate cellular maintenance and systemic homeostasis. Here, we review recent advances on four major longevity regimens, including reduced insulin/insulin-like growth factor 1 signaling (IIS), dietary restriction (DR), mild inhibition of mitochondrial respiration, and germline deficiency. Each longevity-promoting regimen enhances protein and RNA quality control, metabolic remodeling, and stress resistance to delay functional declines with age. Reduced IIS strengthens proteostasis and RNA surveillance. DR remodels metabolism and activates autophagy. Mild mitochondrial inhibition elicits adaptive redox signaling and quality control responses. Germline deficiency links reproductive cues to somatic maintenance. We highlight that longevity arises from the integrated regulation of transcriptional, metabolic, and inter-tissue signaling networks. Our review will provide valuable insights obtained from C. elegans into the conserved mechanisms of aging, facilitating the development of interventions that promote healthy longevity in humans.
秀丽隐杆线虫的衰老是由协调细胞维持和系统稳态的进化保守途径调节的。在这里,我们回顾了四种主要的长寿方案的最新进展,包括减少胰岛素/胰岛素样生长因子1信号(IIS)、饮食限制(DR)、轻度抑制线粒体呼吸和种系缺乏。每一种长寿疗法都能增强蛋白质和RNA质量控制、代谢重塑和抗应激能力,以延缓功能随年龄增长而衰退。降低IIS可增强蛋白质抑制和RNA监视。DR重塑代谢,激活自噬。轻度线粒体抑制引发适应性氧化还原信号和质量控制反应。种系缺陷将生殖线索与体细胞维持联系起来。我们强调,长寿源于转录、代谢和组织间信号网络的综合调控。我们的综述将为秀丽隐杆线虫的保守衰老机制提供有价值的见解,促进促进人类健康长寿的干预措施的发展。

Histone H3 lysine 4 trimethylation (H3K4me3) has been associated with active transcription, yet whether it plays a causative role in gene activation remains an open question. In this study, we reveal that the deletion of Paf1 complex subunit Leo1 in Saccharomyces cerevisiae induces robust transcriptional activation at a subset of genes, particularly those involved in sterol transport, without altering global H3K4me3 levels. These induced genes acquire de novo H3K4me3 at promoter-proximal regions, and this transcriptional induction is entirely dependent on Set1, the sole methyltransferase responsible for H3K4me3. Strikingly, loss of Set1 abolishes expression of these genes, even in the presence of previously established H3K4me3, and their expression is fully restored upon Set1 reintroduction. These effects are specific to Leo1 deficiency and not observed in other Paf1C mutants. Furthermore, Set1-dependent gene activation enhances sterol uptake, underscoring its physiological relevance. Our findings provide direct in vivo evidence that Set1-catalyzed H3K4me3 is not merely a transcriptional correlate, but a context-dependent driver of gene expression.
组蛋白H3赖氨酸4三甲基化(H3K4me3)与活性转录有关,但它是否在基因激活中起致病作用仍然是一个悬而未决的问题。在这项研究中,我们揭示了酿酒酵母中Paf1复合物亚基Leo1的缺失诱导了一部分基因的强大转录激活,特别是那些参与固醇运输的基因,而不会改变全球H3K4me3水平。这些诱导基因在启动子-近端区域重新获得H3K4me3,这种转录诱导完全依赖于Set1,这是唯一负责H3K4me3的甲基转移酶。引人注目的是,即使在先前建立的H3K4me3存在的情况下,Set1的缺失也会消除这些基因的表达,并且在Set1重新引入后,它们的表达完全恢复。这些影响仅针对Leo1缺乏症,而在其他Paf1C突变体中未观察到。此外,set1依赖性基因激活增强了甾醇摄取,强调了其生理相关性。我们的研究结果提供了直接的体内证据,证明set1催化的H3K4me3不仅是转录相关的,而且是基因表达的上下文依赖驱动因素。数据可用性:本研究中讨论的ChIP-seq和RNA-seq数据已存储在NCBI的Gene Expression Omnibus (Edgar et al., 2002)中,可通过GEO Series登录号GSE303595 (https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE303595)和GSE303407 (https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE303407)访问。

Fibrosis is a chronic, progressive disease characterized by the excessive accumulation of extracellular matrix (ECM) in tissues and organs during damage-repair responses. This pathological process can involve almost any tissue or organ and may eventually lead to organ failure, posing a major threat to human health. ECM production is closely related to intercellular communication. As one of the biologically active substances participating in intercellular communication, exosomes have attracted increasing attention in recent years. In particular, noncoding RNAs (ncRNAs) enriched in exosomes regulate gene expression at multiple levels and influence the fibrosis process. Common ncRNAs include miRNA, long ncRNAs, circRNA, and tRNA, which can be selectively loaded into exosomes by various cells to modulate receptor cell functions. In fibrosis-related diseases, the primary sources of exosome-derived ncRNAs (Exo-ncRNAs) include mesenchymal stem cells, macrophages, epithelial cells, and fibroblasts. These Exo-ncRNAs regulate macrophage polarization, epithelial-mesenchymal transition, and fibroblast-myofibroblast transdifferentiation within the microenvironment. In this review, we summarize the regulatory roles and molecular mechanisms of these ncRNAs in the fibrosis process, and discuss Exo-ncRNAs with potential therapeutic effects. Understanding Exo-ncRNAs from different cell sources may provide new research directions for pathological intervention and the treatment of multiorgan fibrosis.
纤维化是一种慢性进行性疾病,其特征是在损伤修复反应过程中组织和器官中细胞外基质(ECM)的过度积累。这种病理过程可以涉及几乎任何组织或器官,并可能最终导致器官衰竭,对人体健康构成重大威胁。ECM的产生与细胞间通讯密切相关。外泌体作为参与细胞间通讯的生物活性物质之一,近年来受到越来越多的关注。特别是外泌体中富集的非编码rna (ncRNAs)在多个水平上调节基因表达并影响纤维化过程。常见的ncrna包括miRNA、lncRNA、circRNA和tRNA,它们可以被各种细胞选择性地装载到外泌体中,以调节受体细胞的功能。在纤维化相关疾病中,外泌体衍生的ncRNAs (Exo-ncRNAs)的主要来源包括间充质干细胞、巨噬细胞、上皮细胞和成纤维细胞。这些exo - ncrna在微环境中调节巨噬细胞极化、上皮-间质转化和成纤维细胞-肌成纤维细胞转分化。在本文中,我们总结了这些ncrna在纤维化过程中的调控作用和分子机制,并讨论了具有潜在治疗作用的exo - ncrna。了解不同细胞来源的exo - ncrna可能为病理干预和多器官纤维化的治疗提供新的研究方向。

Chaperone-mediated autophagy (CMA) is a highly selective form of autophagy responsible for the degradation of specific cytosolic proteins within lysosomes. Recent research has established a significant correlation between CMA and colorectal cancer (CRC). However, the majority of current research focuses on tumor parenchymal cells, with limited attention paid to the expression and role of CMA in tumor stromal cells, particularly in tumor-associated macrophages (TAMs). In this study, we generated myeloid-specific LAMP2A-knockout and knock-in mice to investigate the role of macrophage CMA in dextran sodium sulfate (DSS)-induced colitis and azoxymethane/dextran sodium sulfate-induced CRC. Our findings indicated that the expression of LAMP2A, the rate-limiting component of CMA, was reduced in tumor-associated macrophages of both human and mouse CRC tissues. The knockout of LAMP2A in macrophages exacerbated experimentally induced colitis and colitis-related CRC, whereas its overexpression in macrophages alleviated the progression of colitis and CRC in mice. Notably, we observed increased angiogenesis within the tumor mass of CRC tissues from LAMP2A-mØKO mice. Mechanistically, LAMP2A deficiency elevated the protein levels of HIF-1α, thereby enhancing the secretion of its target genes, vascular endothelial growth factor A and IL-1β, which are 2 important proangiogenic cytokines. Our study suggests that the activation of CMA in macrophages may represent a promising therapeutic strategy for the treatment of CRC.
伴侣介导的自噬(CMA)是一种高度选择性的自噬形式,负责溶酶体内特定细胞质蛋白的降解。最近的研究已经确定了CMA与结直肠癌(CRC)之间的显著相关性。然而,目前的研究大多集中在肿瘤实质细胞,很少关注CMA在肿瘤基质细胞,特别是肿瘤相关巨噬细胞(tumor-associated macrophages, tam)中的表达和作用。在这项研究中,我们制造了骨髓特异性lamp2a敲除和敲入小鼠,以研究巨噬细胞CMA在葡聚糖硫酸钠(DSS)诱导的结肠炎和偶氮氧甲烷(AOM)/DSS诱导的结直肠癌中的作用。我们的研究结果表明,在人和小鼠CRC组织的tam中,CMA的限速成分LAMP2A的表达都降低了。巨噬细胞中LAMP2A的敲除加重了实验性结肠炎和结肠炎相关性CRC,而巨噬细胞中LAMP2A的过表达则减轻了小鼠结肠炎和CRC的进展。值得注意的是,我们观察到LAMP2A-mØKO小鼠CRC组织肿瘤块内血管生成增加。机制上,LAMP2A缺乏升高HIF-1α的蛋白水平,从而增加其靶基因血管内皮生长因子A (VEGFA)和IL-1β的分泌,这是两种重要的促血管生成细胞因子。我们的研究表明,激活巨噬细胞中的CMA可能是治疗结直肠癌的一种有希望的治疗策略。

Recent research has established a significant correlation between CMA and colorectal cancer (CRC). However, the majority of current research focuses on tumor parenchymal cells, with limited attention paid to the expression and role of CMA in tumor stromal cells, particularly in tumor-associated macrophages (TAMs). In this study, we generated myeloid-specific LAMP2A-knockout and knock-in mice to investigate the role of macrophage CMA in dextran sodium sulfate (DSS)-induced colitis and azoxymethane/dextran sodium sulfate-induced CRC. Our findings indicated that the expression of LAMP2A, the rate-limiting component of CMA, was reduced in tumor-associated macrophages of both human and mouse CRC tissues. The knockout of LAMP2A in macrophages exacerbated experimentally induced colitis and colitis-related CRC, whereas its overexpression in macrophages alleviated the progression of colitis and CRC in mice. Notably, we observed increased angiogenesis within the tumor mass of CRC tissues from LAMP2A-mØKO mice. Mechanistically, LAMP2A deficiency elevated the protein levels of HIF-1α, thereby enhancing the secretion of its target genes, vascular endothelial growth factor A and IL-1β, which are 2 important proangiogenic cytokines. Our study suggests that the activation of CMA in macrophages may represent a promising therapeutic strategy for the treatment of CRC.</div></div>","PeriodicalId":18795,"journal":{"name":"Molecules and Cells","volume":"48 12","pages":"Article 100298"},"PeriodicalIF":6.5,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145523929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
