河北农业大学最新Science论文:校史首篇,破解达尔文的“恼人之谜”
生物世界· 2026-02-07 01:00
编辑丨王多鱼 排版丨水成文 自白垩纪中期以来, 被子植物 为何能 迅速崛起 ,并在极短时间内完成爆发式多样化的?这一 达尔文 提出的 "恼人之谜" ( abominable mystery ) ,至今仍 是一个悬而未决的难题 。 基因组学和泛基因组学的最新进展为研究开花植物的快速进化和发育开辟了新途径。 然而,高质量的无间隙基因组和泛基因组资源的缺乏限制了我们全面了解基 因组和泛基因组结构及多样性,以及它们与植物表型变异之间联系的能力。在驯化过程中迅速多样化的作物,例如 白菜 ( Brassica rapa ) ,可能是解答此类 问题的合适对象。 2026 年 2 月 5 日,河北农业大学 赵建军 教授、 马卫 教授、 洪益国 教授及 河南省农科院蔬菜研究所 原玉香 研究员,比利时根特大学 Yves Van de Peer 教 授作为共同通讯作者 ( 马卫、刘远铭、张晓孟、魏小春、李晓楠、刘照坤、袁凌云、李光光为论文共同第一作者 ) ,在国际顶尖学术期刊 Science 期刊发表了 题为: Gapless pangenome analyses reveal fast Brassica rapa subspec ...

编辑丨王多鱼 排版丨水成文 甘蔗 ( Saccharum spp.) 是全球重要的糖料和能源作物,提供了全球约 80% 的食糖和 40% 的乙醇。 现代甘蔗栽培品种具有极其复杂的基因组,这是由种间杂交、极端且不均等的多倍体、非整倍体以及大量 重复序列所塑造的。这些特征模糊了单倍型和等位基因剂量,使遗传研究和育种工作变得复杂。 单一线性 参考基因组 无法适应倍性、染色体数量或渗入背景方面的变异。 被认为是最具发展潜力的可再生能源作物之一。广西是我国最大的甘蔗主产区,甘蔗产业的可持续发展对 保障国家食糖安全具有重要意义。 现代栽培甘蔗品种源于高糖的热带种甘蔗与高抗逆的野生甘蔗在百余年前的杂交回交,其基因组呈现倍性 高、染色体数量多、结构变异频繁和重复序列高度富集等极端复杂特征。这使得传统单一线性参考基因组 难以准确解析甘蔗的遗传结构和等位剂量信息,测序数据在分析过程中普遍存在比对困难和信息丢失。研 究表明,传统 "单一线性基因组"范式已难以满足甘蔗等复杂多倍体作物的研究需求,亟需建立新的基因组 参考和分析体系。 多组学整合:泛基因组指导的多组学分析改善了比对效果,增强了可用信号,发现了更多高置信度的表观 基因组特 ...

Core Viewpoint - The article discusses the development of OpenScholar, an AI assistant designed specifically for researchers to synthesize scientific literature accurately and efficiently, addressing the issue of "hallucination" in existing large language models [2][5][21]. Group 1: OpenScholar Overview - OpenScholar is a retrieval-augmented language model that can intelligently retrieve relevant paragraphs from 45 million open-access papers and generate comprehensive review papers with accurate citations [5][7]. - The model's citation accuracy is comparable to that of human experts and surpasses mainstream models like GPT-4o in multiple tests [5][11]. Group 2: Functionality and Workflow - OpenScholar operates through a three-step process: retrieval of relevant content, generation of answers with citations, and self-feedback for iterative improvement [7][9]. - The system is built on a dedicated data store (OpenScholar DataStore) that allows for transparent and reproducible research [7][21]. Group 3: Evaluation and Performance - The ScholarQABench benchmark was developed to assess AI systems' reliability in synthesizing scientific literature, featuring nearly 3,000 expert-written questions across various fields [12][13]. - OpenScholar demonstrated impressive results in the benchmark, outperforming GPT-4o in citation accuracy and overall usefulness, with human experts favoring OpenScholar's responses over those of GPT-4o [16][18][19]. Group 4: Implications for Research - The introduction of OpenScholar signifies a significant advancement in the application of AI in scientific research, potentially transforming literature reviews from a burdensome task into an efficient exploration process [21][23]. - Future developments may enhance OpenScholar's capabilities, making it a true collaborator for researchers, allowing them to focus more on innovation rather than information filtering [23].
Nature:华人学者证实,肿瘤会欺骗大脑关闭免疫系统,抑制抗癌免疫、促进癌症进展

Core Insights - The article discusses the role of the vagus nerve in tumor-brain communication and its implications for cancer immunity and progression [2][3][5]. Group 1: Tumor-Brain Communication - The study reveals a bidirectional communication between tumors and the brain mediated by the sensory-sympathetic axis, which plays a crucial role in inhibiting anti-cancer immunity and promoting cancer progression [3][6]. - Increased neural innervation of tumors is associated with poor cancer prognosis, highlighting the importance of understanding how the brain perceives and responds to tumors in peripheral organs [5][6]. Group 2: Mechanisms of Action - The research identifies a tumor-brain signaling axis that promotes tumor development by establishing an immunosuppressive tumor microenvironment [6]. - Vagal sensory neurons, which connect visceral organs to the brain, are shown to be involved in the signaling process, with specific neurons transmitting signals from lung tumors to brainstem nuclei, enhancing sympathetic output in the tumor microenvironment [6][7]. Group 3: Therapeutic Implications - Disruption of the sensory-sympathetic pathway through genetic, pharmacological, or chemogenetic methods can significantly inhibit lung tumor growth by enhancing anti-cancer immune responses [8][10]. - Targeting the tumor-brain communication pathway may provide new therapeutic strategies for visceral organ cancers [10].
Cell Metabolism:华南师范大学王璋团队等揭示生酮饮食改善脓毒症相关肺损伤的新机制
生物世界· 2026-02-06 04:26
撰文丨王聪 编辑丨王多鱼 排版丨水成文 脓毒症 被定义为一种危及生命的器官功能障碍综合征,其 特征是对感染的免疫能力受损,导致多器官功能障碍,其中 肺部 是最易受累的器官。 在这项最新研究中,研究团队发现, 生酮饮食 (Ketogenic diet) 通过" 微生物-肠-肺 "信号轴减轻脓毒症诱导的肺损伤。 具体来说,生酮饮食改变了小鼠和人类的肠道微生物群,富集了 罗伊氏乳杆菌 ( Limosilactobacillus reuteri ) 和 植物乳杆菌 ( Lactiplantibacillus plantarum ) 。这些肠道细菌的特定菌株产生一种黄素依赖性单加氧酶 ( flavin-dependent monooxygenase,FMO ) ,能将生酮饮食中的油酸 (oleic acid) 转化为壬二酸 ( azelaic acid ) 。脓毒症期间,壬二酸易位至肺部,通过激活 PPAR-γ 促进中性粒细胞凋亡并扩增 MerTK + 肺泡巨噬细胞,从而增强 胞葬作用 ( efferocytosis ) 并促进肺损伤的消退。 生酮饮食 ( Ketogenic diet,KD) 是一种高脂肪、极低碳水化 ...
Cell Stem Cell:郑州大学于政权团队等揭示睡眠障碍影响肠道干细胞的“脑-肠神经内分泌通路”
生物世界· 2026-02-06 00:18
Core Viewpoint - Sleep disorders are increasingly recognized as a global public health challenge, significantly increasing the risk of various chronic diseases, particularly those related to the gut, such as inflammatory bowel disease and colorectal cancer [3][4]. Group 1: Research Findings - A new "brain-gut dialogue" neuroendocrine regulatory pathway has been revealed, showing that sleep disorders can directly regulate intestinal stem cell function through the "dorsal motor nucleus of the vagus (DMV) - vagus nerve - gut" axis [4]. - The research team constructed a mouse model of sleep deprivation and found that the DMV is a key neural cluster highly sensitive to sleep deprivation, with sleep loss leading to abnormal activation of DMV neurons and increased acetylcholine release to the gut [7]. - Excessive serotonin (5-HT) levels in the gut, resulting from sleep deprivation, significantly impair the regenerative capacity of intestinal stem cells, with a notable decrease in their numbers and epithelial renewal ability observed after just two days of sleep deprivation [7][8]. Group 2: Implications and Interventions - Approximately 95% of the body's serotonin originates from the gut, and its imbalance due to sleep disorders may not only damage the gut barrier but also affect other organs like the liver, pancreas, and cardiovascular system, potentially driving multi-organ dysfunction [8]. - Various intervention strategies targeting this pathway have shown protective effects, including atropine to block muscarinic receptor signaling, the specific HTR4 antagonist GR113808, and the antioxidant vitamin C, which can alleviate gut damage caused by sleep disorders [8][10].
