Lineage plasticity drives treatment resistance in lung adenocarcinoma (LUAD) as cancer cells adopt new identities. In this issue of Genes & Development, Fort and colleagues (doi:10.1101/gad.352742.125) report HNF4α as a key regulator of hybrid identity states and tumor progression in NKX2-1-positive LUAD. Using murine and human models, they show that HNF4α promotes gastrointestinal/liver-like programs and suppresses pulmonary identity by modulating cell identity-specific binding of NKX2-1. In addition, RAS/MEK signaling was implicated in maintenance of this hybrid identity state by regulating NKX2-1 chromatin binding in LUAD. These findings nominate HNF4α as a driver of LUAD plasticity and a potential therapeutic target to overcome resistance.
谱系可塑性驱动肺腺癌(LUAD)的治疗耐药,因为癌细胞采用了新的身份。在本期的《基因》杂志上;Development, Fort及其同事(doi:10.1101/gad.352742.125)报道,HNF4α是nkx2 -1阳性LUAD杂交身份状态和肿瘤进展的关键调节因子。通过小鼠和人类模型,他们发现HNF4α通过调节NKX2-1的细胞特异性结合来促进胃肠道/肝脏样程序并抑制肺身份。此外,RAS/MEK信号通过调节LUAD中NKX2-1染色质结合参与了这种杂交身份状态的维持。这些发现表明,HNF4α是LUAD可塑性的驱动因素,也是克服耐药性的潜在治疗靶点。

Although vertebrates share a similar body plan, different vertebrate species can develop at very different rates. In recent years, there has been an increasing appreciation of the fact that protein stability regulates the pace of differentiation. For example, global differences in protein stability may help explain why humans develop more slowly than mice. Mechanisms controlling the stability of particular proteins are also likely to play a role. In keeping with this idea, in this issue of Genes & Development, Meijer and colleagues (doi:10.1101/gad.352909.125) report that cells must keep tight control over the stability of the Notch1 intracellular domain (NICD) to tune developmental timing in the context of human somitogenesis.
尽管脊椎动物有着相似的身体结构,不同的脊椎动物物种可以以不同的速度发育。近年来,人们越来越认识到蛋白质的稳定性调节着分化的速度。例如,蛋白质稳定性的全球差异可能有助于解释为什么人类比老鼠发育得慢。控制特定蛋白质稳定性的机制也可能发挥作用。为了与这个观点保持一致,在这一期的《基因》杂志上;发展,Meijer和他的同事(doi:10.1101/gad.352909.125)报告说,在人类体细胞发生的背景下,细胞必须严格控制Notch1细胞内结构域(NICD)的稳定性,以调节发育时间。

In response to excess nutrients, white adipose tissue expands by both generating new adipocytes and upregulating lipogenesis in existing adipocytes. Here, we performed a genome-wide functional CRISPR screen to identify regulators of adipogenesis in the mouse 3T3-L1 preadipocyte model. In this pooled screening strategy, we used FACS to isolate populations based on lipid content, gating for fluorescence intensity of lipophilic fluorescent BODIPY dye. Additionally, we categorized whether the gene functions primarily during mitotic clonal expansion, lipogenesis, or both. We found that translation initiation and ubiquitin-dependent protein stability regulators drive both adipogenic fate change and lipogenesis. We further supported these findings with proteomics, demonstrating that essential changes in protein reprogramming can drive or inhibit 3T3-L1 adipogenesis independent of transcription. Furthermore, we demonstrated that specific branches of the hypusination pathway, a conserved regulator of translation initiation, are critical for translating adipogenic inducers of mitotic clonal expansion and that the neddylation/ubiquitin pathway modulates insulin sensitivity during lipogenesis.
作为对过量营养的反应,白色脂肪组织通过产生新的脂肪细胞和上调现有脂肪细胞的脂肪生成来扩张。在这里,我们进行了全基因组功能CRISPR筛选,以鉴定小鼠3T3-L1前脂肪细胞模型中脂肪形成的调节因子。在这种混合筛选策略中,我们使用FACS根据脂质含量分离群体,对亲脂性荧光BODIPY染料的荧光强度进行筛选。此外,我们分类了该基因是否主要在有丝分裂克隆扩增、脂肪生成或两者中起作用。我们发现翻译起始和泛素依赖的蛋白质稳定性调节因子驱动脂肪生成命运的改变和脂肪生成。我们用蛋白质组学进一步支持了这些发现,证明蛋白质重编程的基本变化可以独立于转录驱动或抑制3T3-L1脂肪形成。此外,我们证明了翻译起始的保守调节因子hypusination通路的特定分支对于翻译有丝分裂克隆扩增的脂肪生成诱导剂至关重要,并且类化修饰/泛素通路调节脂肪生成过程中的胰岛素敏感性。

Killing wisely: precision senolytics in the age of frailty 明智地杀戮:脆弱时代的精准老年学

Cellular senescence plays a dual role in tissue biology by promoting tumor suppression and wound healing when transient but driving inflammation, fibrosis, and age-related disease when persistent. The growing recognition that senescent cell clearance can reverse these pathologies has catalyzed efforts to develop therapeutics that preferentially kill senescent cells (also known as “senolytics”). However, clinical translation from bench to bedside remains challenging due to senescent state heterogeneity, limited biomarkers, off-target toxicities, and the frailty of aged patients. Small molecule senolytics, although promising, often lack defined mechanisms of action and pose safety concerns that may constrain their use in older adults. Emerging precision approaches, including those that exploit surface markers and leverage engineered immune therapies, offer a rational and potentially more selective path forward. Here we highlight recent advances in senescence profiling and targeted clearance strategies, emphasizing the need for therapies designed with both biological complexity and the needs of aging populations in mind.
细胞衰老在组织生物学中起双重作用,短暂时促进肿瘤抑制和伤口愈合,但持续时驱动炎症、纤维化和年龄相关疾病。越来越多的人认识到,清除衰老细胞可以逆转这些病理,这促使人们努力开发优先杀死衰老细胞的治疗方法(也称为“抗衰老药物”)。然而,由于衰老状态的异质性、有限的生物标志物、脱靶毒性和老年患者的虚弱,从实验室到床边的临床转化仍然具有挑战性。小分子抗衰老药物虽然很有前景,但往往缺乏明确的作用机制,并且存在安全问题,这可能限制其在老年人中的使用。新兴的精确方法,包括那些利用表面标记和利用工程免疫疗法的方法,提供了一种合理的、可能更具选择性的前进道路。在这里,我们重点介绍了衰老分析和靶向清除策略的最新进展,强调需要在设计治疗时考虑到生物复杂性和老龄化人口的需求。

Scaling life as an interspecies hallmark of aging 缩放生命是物种间衰老的标志

Across species, the “pace of life”—encompassing development, reproduction, and senescence—varies widely, yet the molecular mechanisms that regulate these interspecies trajectories of aging remain elusive. Even among vertebrates, a 1000-fold difference in life span is observed between species, ranging from several months in the turquoise killifish to half a millennium in the Greenland shark. As a relatively “young” area of investigation, aging research lacks the unifying conceptual frameworks that anchor more established disciplines, such as neuroscience. Therefore, current theories, which in some cases provide contradicting predictions, rely heavily on experimental data to mature. These contradictions not only define key outstanding questions but also illuminate fertile ground for transformative research.
物种间的“生命节奏”——包括发育、繁殖和衰老——差异很大,然而调节这些物种间衰老轨迹的分子机制仍然难以捉摸。即使在脊椎动物中,物种之间的寿命也有1000倍的差异,从绿松石鳉的几个月到格陵兰鲨的5000年不等。作为一个相对“年轻”的研究领域,衰老研究缺乏统一的概念框架,而这些框架可以锚定更成熟的学科,如神经科学。因此,目前的理论,在某些情况下提供矛盾的预测,在很大程度上依赖于实验数据来成熟。这些矛盾不仅定义了关键的突出问题,而且为变革性研究提供了肥沃的土壤。

A noncanonical Pol III-dependent, Microprocessor-independent biogenesis pathway generates a germline-enriched miRNA family 一个非规范的依赖于Pol iii,不依赖于微处理器的生物发生途径产生了一个种系富集的miRNA家族

MicroRNAs (miRNAs) are short RNAs that post-transcriptionally regulate gene expression. In canonical miRNA biogenesis, primary miRNAs are transcribed from intergenic loci or intronic regions by RNA polymerase II and sequentially cleaved by the Microprocessor complex and Dicer, and the resulting mature miRNAs are loaded into Argonaute to repress target mRNAs. A minority of miRNAs are generated via noncanonical biogenesis pathways that bypass the Microprocessor complex and/or Dicer. Here, we describe a new Pol III-dependent, Microprocessor-independent, and Dicer-dependent biogenesis pathway exemplified by the mir-1829 family in Caenorhabditis elegans. Although the mir-1829 family loci reside in intronic regions of protein-coding genes, we show that the miRNAs are derived from independent Pol III transcripts. Unlike other Pol III-dependent miRNAs, the mir-1829 family small RNAs are the dominant species derived from their loci rather than fragments of a larger functional noncoding RNA. These germline-enriched miRNAs are loaded in multiple miRNA Argonautes, including the recently characterized germline Argonaute ALG-5, which we demonstrated is repressive when tethered to a reporter transcript. We extend these findings, identifying additional Pol III transcribed and noncanonical small RNAs in C. elegans and human data sets, including human miR-4521. These young, noncanonical miRNAs may represent an early snapshot in the evolution of de novo miRNA genes.
MicroRNAs (miRNAs)是一种转录后调控基因表达的短rna。在典型的miRNA生物发生中,初级miRNA由RNA聚合酶II从基因间位点或内含子区转录,然后由微处理器复合体和Dicer依次切割,产生的成熟miRNA被装载到Argonaute中抑制目标mrna。少数mirna是通过绕过微处理器复合物和/或Dicer的非规范生物发生途径产生的。在这里,我们描述了一个新的Pol iii依赖性,微处理器依赖性和dicer依赖性的生物发生途径,以秀丽隐杆线虫中的mir-1829家族为例。尽管mir-1829家族位点位于蛋白质编码基因的内含子区域,但我们发现mirna来源于独立的Pol III转录本。与其他依赖Pol iii的mirna不同,mir-1829家族小RNA是来自其基因座而不是更大的功能性非编码RNA片段的优势种。这些生殖系富集的miRNA装载在多种miRNA Argonaute中,包括最近表征的生殖系Argonaute ALG-5,我们证明当连接到报告转录本时,它是抑制性的。我们扩展了这些发现,在秀丽隐杆线虫和人类数据集中鉴定了额外的Pol III转录和非规范小rna,包括人类miR-4521。这些年轻的、非规范的miRNA可能代表了新生miRNA基因进化的早期快照。

Patient genomics and mouse functional genetics have revealed that senescence is a barrier to metastatic progression of prostate cancer. Many efforts focus on eliminating senescent cells, whereas others aim to elucidate distinct characteristics that set them apart from normal and aging cells. Here, we discuss how exploration of the redox state of senescent cells could help define new markers and pro-oxidant vulnerabilities, drawing analogy to what is known about the redox sensitivity of proliferating cancer cells.

Caenorhabditis elegans has been at the forefront of research on mechanisms of age-related decline for the past 30 years. Despite its popularity in longevity research, C. elegans is underappreciated for its potential to study complex behaviors and the progressive decline in these functions with age. Using assays of learning and memory, we have identified genetic pathways that regulate these behaviors and identified new mechanisms to boost these functions with age in both worms and mice. Because C. elegans is so highly conserved, some of these recently described mechanisms may be good targets to prevent human cognitive decline with age.
在过去的30年里,秀丽隐杆线虫一直处于与年龄相关的衰退机制研究的前沿。尽管秀丽隐杆线虫在长寿研究中很受欢迎,但它在研究复杂行为和这些功能随着年龄的增长而逐渐下降方面的潜力却没有得到充分的重视。通过对学习和记忆的分析,我们已经确定了调节这些行为的遗传途径,并确定了蠕虫和小鼠随着年龄增长而增强这些功能的新机制。由于秀丽隐杆线虫是如此高度保守,这些最近描述的机制中的一些可能是防止人类认知能力随着年龄增长而下降的良好目标。

Model organisms such as yeast, worms, flies, and mice were key to discovering genes and other factors controlling life span and directly improved our understanding of human aging. Today, genomic tools allow study of a broader range of species, including those with short or long life spans, closely related species with different aging rates, or differences in interspecies aging. Models such as killifish, bats, and ants have much to teach us about human aging.

酵母菌、蠕虫、苍蝇和老鼠等模式生物是发现控制寿命的基因和其他因素的关键,并直接提高了我们对人类衰老的理解。今天,基因组工具允许研究更广泛的物种,包括那些寿命短或长的物种,衰老速度不同的近亲物种,或物种间衰老的差异。像鳉鱼、蝙蝠和蚂蚁这样的模型可以教会我们很多关于人类衰老的知识。它们还揭示了一个灵活的生物工具包,当进化压力推动生长、繁殖或适应力与年龄相关的衰退重新平衡时,物种可以使用它。

Aging is the greatest risk factor for most diseases. We propose that aging manifests as disease as a function of tumor-suppressive capabilities. Adequate tumor suppression results in cell death or an accumulation of damaged cells leading to inflammation and tissue dysfunction that underlies diseases such as cardiovascular disease, neurodegenerative diseases, or type 2 diabetes. Conversely, inadequate tumor suppression leads to cancer. Telomeres are central to this process because they oppose hyperproliferation that is required for cancer initiation by enforcing two potent tumor suppressor mechanisms: senescence and crisis. Although senescent cells promote age-related diseases via inflammatory signaling, crisis cells have lost the p53 and RB pathways, have more unstable genomes, and harbor shorter telomeres, all of which could increase inflammation to a greater degree than is seen in senescence. This model emphasizes the intimate relationship between aging, telomeres, tumor suppression, and inflammation and suggests that crisis cells may represent an unexplored driver of inflammation in advanced age.
衰老是大多数疾病的最大危险因素。我们提出,衰老作为肿瘤抑制能力的功能表现为疾病。充分的肿瘤抑制会导致细胞死亡或受损细胞的积累,导致炎症和组织功能障碍,这是心血管疾病、神经退行性疾病或2型糖尿病等疾病的基础。相反,肿瘤抑制不足会导致癌症。端粒是这个过程的核心,因为它们通过执行两种有效的肿瘤抑制机制:衰老和危机,来对抗癌症起始所需的过度增殖。尽管衰老细胞通过炎症信号促进与年龄相关的疾病,但危机细胞失去了p53和RB通路,基因组更不稳定,端粒更短,所有这些都可能比衰老细胞更严重地增加炎症。该模型强调衰老、端粒、肿瘤抑制和炎症之间的密切关系,并表明危机细胞可能代表了一种未被探索的老年炎症驱动因素。
