The mastery of fire transformed human evolution through advantages spanning diet, behavior, physiology, and ecology. While these benefits are well established, here we highlight a previously overlooked cost — and selective pressure — unique to humans: high-temperature burn injury. Unlike other species, humans and their hominin ancestors have faced increased lifetime risk of burns, which we argue has driven genetic adaptation. Drawing on comparative genomic evidence across primates, we suggest that genes associated with burn injury response — relating to wound healing and inflammation — show signs of accelerated evolution in humans. We propose that recurrent exposure to burns acted as a selective force in our lineage, helping to explain both beneficial adaptations and paradoxical maladaptive responses to severe injury. By framing burns as an evolutionary pressure, the Burn Selection Hypothesis invites a re-evaluation of how fire shaped human biology and offers new perspectives for understanding both the evolutionary past and modern burn care.

对火的掌握通过饮食、行为、生理和生态方面的优势改变了人类的进化。虽然这些好处是公认的,但在这里,我们强调了一个以前被忽视的成本和人类特有的选择压力:高温烧伤。与其他物种不同,人类和他们的古人类祖先面临着终生烧伤的风险增加,我们认为这推动了基因适应。通过比较灵长类动物的基因组证据,我们认为与烧伤反应相关的基因——与伤口愈合和炎症有关——在人类中显示出加速进化的迹象。我们认为,在我们的谱系中,反复暴露于烧伤是一种选择性的力量,有助于解释对严重损伤的有益适应和矛盾的适应不良反应。通过将烧伤视为一种进化压力,烧伤选择假说重新评估了火灾如何塑造人类生物学,并为理解过去的进化和现代烧伤护理提供了新的视角。

Stem cell populations employ cell-intrinsic and niche-mediated mechanisms to preserve long-term self-renewal and regenerative potential. We propose that tumor-initiating cells (TICs) hijack this developmental circuitry to sustain their growth and establish an early immunosuppressive microenvironment during malignant progression. Recent work implicates CXCR4+ tissue-resident macrophages (TRMs) in the mammary gland as a central orchestrator of this process. Conserved CXCL12/CXCR4-AKT-β-catenin signaling links CXCR4+ TRM support of normal mammary stem cells to TIC maintenance, underscoring how developmental niches are exploited in malignancy. During tumorigenesis, aberrant CXCL12 production from tumor-associated fibroblasts promotes the expansion of CXCR4+ TRMs, while CXCR4 signaling enhances ALDH1A2-dependent retinoic acid production, which induces regulatory T cells and thereby suppresses anti-tumor immunity at the earliest stages of tumor development. From this perspective, early immune evasion is not only a hallmark of cancer but also a therapeutic window. Targeting TRMs early in cancer development could delay, or even prevent, malignant initiation. More broadly, we propose that TIC–niche crosstalk constitutes a tractable vulnerability, and that incorporating TRM-directed interventions alongside conventional and immune-based therapies may shift the balance toward durable tumor control.

干细胞群体利用细胞内在和生态位介导的机制来保持长期的自我更新和再生潜力。我们提出肿瘤启动细胞(tic)劫持这种发育通路以维持其生长,并在恶性进展期间建立早期免疫抑制微环境。最近的研究表明,乳腺中的CXCR4+组织驻留巨噬细胞(TRMs)是这一过程的中心协调者。保守的CXCL12/CXCR4- akt -β-catenin信号将CXCR4+ TRM支持正常乳腺干细胞与TIC维持联系起来,强调了发育利基如何在恶性肿瘤中发挥作用。在肿瘤发生过程中,肿瘤相关成纤维细胞产生的异常CXCL12促进了CXCR4+ TRMs的扩增,而CXCR4信号传导增强了aldh1a2依赖性视黄酸的产生,从而诱导调节性T细胞,从而在肿瘤发展的早期阶段抑制抗肿瘤免疫。从这个角度来看,早期免疫逃避不仅是癌症的一个标志,也是一个治疗窗口。在癌症发展早期靶向trm可以延缓甚至预防恶性肿瘤的发生。更广泛地说,我们认为TIC-niche串扰构成了一个可处理的脆弱性,并且将trm导向的干预与传统和基于免疫的治疗结合起来可能会将平衡转向持久的肿瘤控制。

We review recent multi-omics analyses of the coral heat stress response to explore the generality of the Oxidative Theory of Coral Bleaching (OTCB), which posits that algal symbiont release is the final act of defense by the coral host to survive alga-derived oxidative stress. The OTCB is particularly relevant given that ocean warming, which is accelerating under climate change, has proven devastating for corals, leading to the bleaching phenotype and widespread reef loss. Multi-omics results, in combination with other data, such as genome-wide association studies, support the idea that coral bleaching is a multifactorial response that reflects a wide array of causes and effects and is population-specific under most conditions, with coral ploidy and genotype being critical to bleaching sensitivity. This perspective leverages the location, algal and prokaryotic microbiome, and host genotype-specific aspects of coral resilience to promote a new “personal genomics” approach to coral conservation, analogous to that used in human health.

我们回顾了最近珊瑚热应激反应的多组学分析,以探索珊瑚白化氧化理论(OTCB)的普遍性,该理论认为藻类共生体释放是珊瑚宿主在藻类衍生的氧化应激中生存的最后防御行为。考虑到在气候变化下加速的海洋变暖已被证明对珊瑚具有破坏性,导致白化表型和广泛的珊瑚礁损失,OTCB尤为重要。多组学结果与其他数据(如全基因组关联研究)相结合,支持珊瑚白化是一种多因素反应的观点,反映了广泛的因果关系,在大多数情况下具有种群特异性,珊瑚的倍性和基因型对白化敏感性至关重要。这一观点利用珊瑚复原力的位置、藻类和原核微生物组以及宿主基因型特定方面来促进珊瑚保护的一种新的“个人基因组学”方法,类似于在人类健康中使用的方法。

<p>Originally, I planned to share these thoughts under the heading ‘Brainless animals still sleep’, but the insights are deeper than that. Still, a recent study showing that cnidarians, ‘lowly’ animals with neural networks but without brains, such as jellyfish and sea anemones, exhibit sleep, is a good place to start [<span>1</span>]. Thus, sleep actually evolved before a centralized nervous system, which had already become clear with the discovery of sleep-like states in jellyfish almost 10 years ago [<span>2</span>]. The latest, more specific, findings bolster a theory that sleep evolved, at least in part, to protect the DNA in individual nerve cells, helping to repair damage that builds up while animals are awake. So, what are these specific findings? It has been known for over a decade that sleep is critical for maintaining neuronal genomic integrity, as it reduces DNA damage, which normally accumulates in nerve cells of (in)vertebrates (e.g., flies and mice) during wakefulness. This stems from, among other things, higher metabolic activity and associated reactive oxygen species (ROS). Therefore, one of the benefits of sleep, and probably its oldest, is protecting neurons from accumulating DNA damage. The jellyfish model, <i>Cassiopea andromeda</i>, sleeps at night, while the sea anemone model, <i>Nematostella vectensis</i>, sleeps at dawn. But indeed, in both cases, sleep deprivation and mutagens increased neuronal DNA damage and sleep pressure, while sleep, both spontaneous and induced, improved genome stability. As an author of [<span>1</span>], Lior Appelbaum, states: “Neurons are very precious”, “they don't divide, so you need to keep them intact” [<span>3</span>]. Which brings us to the deeper question: why don't neurons (normally) divide anymore?</p><p>At the dawn of metazoan evolution, multicellularity and differentiation towards nerve cells allowed further encoding of the state of the world, including its history. This introduced concepts such as critical periods during embryogenesis, which allowed neural networks to start monitoring different parts of the body. Such mirroring evolved into a full representation of the body in the central nervous systems of ever more complex animals. Alongside this, the development of highly dynamic connections with varying strengths between ever-increasing numbers of neurons enabled the storage of exponentially growing amounts of information about the environment these bodies inhabit. In vertebrates, a single neuron can have between 10<sup>3</sup> and 10<sup>4</sup> synaptic connections. Thus, while we can easily replace dedicated cells such as muscle, skin, liver, or blood cells, neurons are exceptional because the information they help to encode is eroded upon their loss. As such, they will become ‘irreplaceable’. The new results with cnidarians demonstrate that such a threshold is reached surprisingly quickly.</p><p>This all fits nicely with an informative recent review about “signaling roles for
最初,我打算在“无脑动物仍在睡觉”的标题下分享这些想法,但我的见解远不止于此。不过,最近的一项研究表明,刺胞动物是一种有神经网络但没有大脑的“低级”动物,比如水母和海葵,它们也有睡眠,这是一个开始[1]的好地方。因此,睡眠实际上是在中枢神经系统出现之前进化而来的,这一点随着近10年前在水母身上发现类似睡眠的状态而变得清晰起来。最新的、更具体的发现支持了一种理论,即睡眠的进化,至少在一定程度上,是为了保护单个神经细胞的DNA,帮助修复动物清醒时形成的损伤。那么,这些具体发现是什么呢?十多年来,人们已经知道睡眠对维持神经元基因组的完整性至关重要,因为它可以减少DNA损伤,而DNA损伤通常在清醒时积聚在脊椎动物(如苍蝇和老鼠)的神经细胞中。除其他外,这源于更高的代谢活性和相关的活性氧(ROS)。因此,睡眠的好处之一,可能也是最古老的好处之一,就是保护神经元免受DNA损伤的累积。水母模型仙后座(Cassiopea andromeda)在晚上睡觉,而海葵模型线虫(Nematostella vectensis)在黎明睡觉。但事实上,在这两种情况下,睡眠剥夺和诱变剂都增加了神经元DNA损伤和睡眠压力,而睡眠,无论是自发的还是诱导的,都提高了基因组的稳定性。正如[3]的作者Lior Appelbaum所说:“神经元非常珍贵”,“它们不会分裂,所以你需要保持它们的完整”。这给我们带来了更深层次的问题:为什么神经元(通常)不再分裂?在后生动物进化的初期,多细胞和向神经细胞的分化使得对世界状态的进一步编码,包括它的历史。这引入了诸如胚胎发生的关键时期之类的概念,使神经网络能够开始监测身体的不同部位。在更复杂的动物的中枢神经系统中,这种镜像进化成了身体的完整代表。除此之外,不断增加的神经元数量之间具有不同强度的高度动态连接的发展,使得存储这些身体所处环境的信息呈指数级增长。在脊椎动物中,一个神经元可以有103到104个突触连接。因此,虽然我们可以很容易地替换专用细胞,如肌肉、皮肤、肝脏或血细胞,但神经元是特殊的,因为它们帮助编码的信息在它们丢失时被侵蚀了。因此,它们将变得“不可替代”。刺胞动物的新结果表明,达到这个阈值的速度惊人。这与最近一篇关于“星形细胞脂质代谢在脑功能中的信号作用”的综述非常吻合。在这里,作者展示了建立的大脑能量稳态代谢模型,星形细胞-神经元乳酸穿梭假说,如何扩展到乳酸和脂肪酸氧化(FAO)衍生的ROS在大脑正常功能和维持中的信号作用。顺便说一句,它们也隐含地推翻了两个长期流行的关于神经元中线粒体(mt) FAO相对缺乏的“解释”:(i) FAs不能通过血脑屏障(但星形胶质细胞确实大量氧化它们);(ii)饥饿的神经元可能会“吃掉”自己的保护髓鞘,如果他们使用mt FAO(但髓鞘在外面覆盖轴突,由少突胶质细胞制造,它们自己使用这一途径产生丰富的ATP来生产髓鞘)。由于胶质细胞,如少突胶质细胞和星形胶质细胞(本身也是异质的)可以得到补充,而神经元的死亡导致不可替代的损失,因此,将mt FAO与较高的内部活性氧形成率和细胞死亡率联系起来似乎是一种更可能的解释[10]。事实上,该综述提到星形胶质细胞使用FAO通过mt复合体I控制ROS的产生,用于信号目的,尽管它强调较弱的复合体I - iii相互作用的作用,而不是来自较高水平的还原泛醌的反向电子传递。两者可能都有作用;参见[6,7]。自然界几乎没有绝对的存在,神经元似乎在特殊条件下偶尔会表现出mt FAO(例如,当面临“峰值需求”或在其神经末梢时),但“……星形胶质细胞总体上比神经元更能胜任FAO”[4]。这篇综述描绘了一幅近乎诗意的画面:少突胶质细胞和星形胶质细胞保护性地“溺爱”神经元,这是一种高度复杂、精细调节的FAO和相关ROS生成的平衡行为。脊椎动物的大脑确实已经发展了很长一段路,但一些关键的选择力量在它们卑微的开始时就已经被识别出来了。

The Hippo signaling pathway plays a key role in organ size control in normal development and tumorigenesis. While many components of this pathway are well understood, its upstream regulation remains unclear. Among the most enigmatic upstream regulators are the protocadherins Dachsous and Fat. These transmembrane proteins regulate a growth-promoting complex composed of the atypical myosin Dachs, the adaptor protein Dlish, and the palmitoyltransferase Approximated (together termed the core complex).

Hippo信号通路在正常发育和肿瘤发生的器官大小控制中起关键作用。虽然这一途径的许多组成部分已被很好地理解,但其上游调控仍不清楚。其中最神秘的上游调节因子是原钙粘蛋白Dachsous和Fat。这些跨膜蛋白调节由非典型肌球蛋白Dachs、适应蛋白Dlish和棕榈酰基转移酶(统称为核心复合物)组成的促进生长的复合物。我们提出,默认情况下,核心复合体促进生长,而Dachsous和Fat,以前被认为是拮抗作用,也可以协同作用,抑制核心复合体的功能,从而限制生长。了解Dachsous-Fat信号传导的分子机制有助于了解多细胞生物如何精确控制器官大小。

Life on Earth has evolved as a series of evolutionary transitions, during which lower-level units merged to form a new and more complex higher-level entity. Besides few canonical examples, many life forms exist for which it remains unclear whether or not they are about to complete the transition. This paucity of mechanistic understanding is likely due to an overemphasis on few model systems and a lack of criteria to compare disparate biological units. Here, we aim at filling this gap by proposing a new framework to classify different forms of biological organization, which considers two fundamental aspects: (i) the physiological component and (ii) the evolutionary component. Categorizing different biological units according to whether and how these aspects are represented yields six types of structural organization. Our framework allows to compare different organizational forms, and, in this way, provide insight into the evolutionary processes giving rise to these arrangements.

地球上的生命是通过一系列的进化转变而进化的,在此过程中,低级单位合并形成一个新的、更复杂的高级实体。除了少数几个典型的例子外,许多生命形式的存在仍然不清楚它们是否即将完成转变。这种机制理解的缺乏可能是由于过度强调少数模型系统和缺乏比较不同生物单位的标准。在这里,我们旨在通过提出一个新的框架来填补这一空白,该框架考虑了两个基本方面:(i)生理成分和(ii)进化成分来分类不同形式的生物组织。根据这些方面是否和如何表现,对不同的生物单位进行分类,产生六种结构组织类型。我们的框架允许比较不同的组织形式,并且,通过这种方式,提供对产生这些安排的进化过程的洞察。

In eukaryotic cells, genomic DNA is packaged into chromatin, restricting the access of regulatory proteins and thus regulating key processes such as transcription, replication, recombination, and the repair of DNA. Barrier-to-autointegration factor (BAF) plays key roles in organizing chromatin architecture and nuclear functions. BAF bridges DNA segments and connects them to Lamin A/C and inner nuclear membrane proteins containing the LEM domain, ensuring proper chromatin organization and nuclear envelope assembly and repair. Over the last three decades, multiple structural studies have revealed that BAF dimerizes to bind DNA and shapes higher-order chromatin structure. In this review, we summarize the structural features of BAF in complexes with its binding partners and explore how these interactions contribute to maintaining nuclear integrity and regulating genome function.

在真核细胞中,基因组DNA被包装成染色质,限制了调节蛋白的进入,从而调节了转录、复制、重组和DNA修复等关键过程。自整合障碍因子(Barrier-to-autointegration factor, BAF)在染色质结构和核功能的组织中起着关键作用。BAF桥接DNA片段,并将它们连接到Lamin A/C和含有LEM结构域的核膜蛋白,确保染色质组织和核膜的组装和修复。在过去的三十年中,多项结构研究表明,BAF二聚体结合DNA并形成高阶染色质结构。在这篇综述中,我们总结了BAF及其结合伙伴复合物的结构特征,并探讨了这些相互作用如何有助于维持核完整性和调节基因组功能。
