    衰老目前被认为是多个独立表现的生物过程的结果,彼此加强,并在整体上导致衰老表型。针对衰老的特定潜在原因的遗传和药物方法已用于延长从酵母到哺乳动物的模型生物的寿命和健康时间。然而,大多数干预措施只显示出适度的益处。如果我们考虑到即使一个衰老过程被成功治疗,这个结果是可以预期的,其他老化途径可能保持完整。因此,解决衰老问题可能需要一次针对的不是一个,而是许多根本原因。在这里,我们回顾了旨在延长哺乳动物寿命的联合疗法的挑战和成功,并为其发展提出了新的方向。我们得出的结论是,通过结合针对相同或不同衰老特征的干预措施,可以实现对哺乳动物寿命的累加和协同作用。然而,同时针对多个标志的研究数量惊人地有限.我们认为,这种方法是有希望的,因为它是研究不足。
    Aging is currently viewed as a result of multiple biological processes that manifest themselves independently, reinforce each other and in their totality lead to the aged phenotype. Genetic and pharmaceutical approaches targeting specific underlying causes of aging have been used to extend the lifespan and healthspan of model organisms ranging from yeast to mammals. However, most interventions display only a modest benefit. This outcome is to be expected if we consider that even if one aging process is successfully treated, other aging pathways may remain intact. Hence solving the problem of aging may require targeting not one but many of its underlying causes at once. Here we review the challenges and successes of combination therapies aimed at increasing the lifespan of mammals and propose novel directions for their development. We conclude that both additive and synergistic effects on mammalian lifespan can be achieved by combining interventions that target the same or different hallmarks of aging. However, the number of studies in which multiple hallmarks were targeted simultaneously is surprisingly limited. We argue that this approach is as promising as it is understudied.

    口腔鳞状细胞癌(OSCC)被认为是最常见的头颈部鳞状细胞癌(HNSCC),因为它拥有90%的HNSCC病例,这些病例来自口腔中的多个位置。在过去的三十年中,侵袭性肿瘤OSCC的诊断和治疗进展甚微。然而,深入了解OSCC的发病机制,分期和分级,标志,和致病因素是OSCC患者晚期诊断和治疗的首要要求。因此,本综述旨在理解OSCC的患病率,分期和分级,分子发病机制包括癌前阶段,各种标志,病因学,诊断方法,治疗(包括FDA批准的具有作用机制和副作用的药物),和治疗医生。当前的评论更新,为了更好地理解OSCC进展肿瘤促进炎症,持续增殖信号,生长抑制信号/凋亡能力逃避是需要考虑的三个最重要的标志。该综述表明,在所有病因因素中,烟草的消费是导致OSCC高发病率的主要原因。在OSCC诊断中,活检被认为是金标准,然而,甲苯胺蓝染色是最简单、无创、准确度高的方法。虽然有多种治疗剂可用于癌症治疗,然而,只有少数被FDA批准专门用于OSCC治疗。本综述建议在所有可用的OSCC治疗中,基于抗体的CAR-NK是未来癌症治疗的一种有前景的治疗方法.目前的审查还表明,治疗药物促进了癌症诊断和治疗的进步,然而,需要额外的工作来完善治疗与不同方式结合在癌症治疗中的作用。
    Oral squamous cell carcinoma (OSCC) is considered the most common type of head and neck squamous cell carcinoma (HNSCC) as it holds 90 % of HNSCC cases that arise from multiple locations in the oral cavity. The last three decades witnessed little progress in the diagnosis and treatment of OSCC the aggressive tumor. However, in-depth knowledge about OSCC\'s pathogenesis, staging & grading, hallmarks, and causative factors is a prime requirement in advanced diagnosis and treatment for OSCC patients. Therefore present review was intended to comprehend the OSCCs\' prevalence, staging & grading, molecular pathogenesis including premalignant stages, various hallmarks, etiology, diagnostic methods, treatment (including FDA-approved drugs with the mechanism of action and side effects), and theranostic agents. The current review updates that for a better understanding of OSCC progress tumor-promoting inflammation, sustained proliferative signaling, and growth-suppressive signals/apoptosis capacity evasion are the three most important hallmarks to be considered. This review suggests that among all the etiology factors the consumption of tobacco is the major contributor to the high incidence rate of OSCC. In OSCC diagnosis biopsy is considered the gold standard, however, toluidine blue staining is the easiest and non-invasive method with high accuracy. Although there are various therapeutic agents available for cancer treatment, however, a few only are approved by the FDA specifically for OSCC treatment. The present review recommends that among all available OSCC treatments, the antibody-based CAR-NK is a promising therapeutic approach for future cancer treatment. Presently review also suggests that theranostics have boosted the advancement of cancer diagnosis and treatment, however, additional work is required to refine the role of theranostics in combination with different modalities in cancer treatment.

    用于人类发展的新型2D和3D模型的出现,包括滋养层干细胞和囊虫,扩大了调查早期发育事件的机会,逐渐照亮人类发展的神秘领域。虽然这些创新带来了新的前景,为这些模型的细胞来源建立明确的基准已经变得至关重要。我们的目的是提出一个全面的表征多能和滋养干细胞模型,通过采用转录组学的组合,蛋白质组学,表观遗传,和代谢方法。我们的研究结果表明,延伸的多能干细胞与引发的多能干细胞具有许多共同的特征,除了代谢活动。此外,我们的研究表明,DNA低甲基化和高代谢活性决定了滋养干细胞。这些结果强调了考虑多能性的多个标志而不是依赖于单个标准的必要性。乘法标志减轻了阶段匹配偏差。
    The advent of novel 2D and 3D models for human development, including trophoblast stem cells and blastoids, has expanded opportunities for investigating early developmental events, gradually illuminating the enigmatic realm of human development. While these innovations have ushered in new prospects, it has become essential to establish well-defined benchmarks for the cell sources of these models. We aimed to propose a comprehensive characterization of pluripotent and trophoblastic stem cell models by employing a combination of transcriptomic, proteomic, epigenetic, and metabolic approaches. Our findings reveal that extended pluripotent stem cells share many characteristics with primed pluripotent stem cells, with the exception of metabolic activity. Furthermore, our research demonstrates that DNA hypomethylation and high metabolic activity define trophoblast stem cells. These results underscore the necessity of considering multiple hallmarks of pluripotency rather than relying on a single criterion. Multiplying hallmarks alleviate stage-matching bias.

    年龄歧视是一种歧视,其特征是对老年和衰老的负面社会表征,偏见和成见导致老年人的排斥和边缘化,通常认为它们是脆弱和非生产性的。出于这个原因,它被认为是健康衰老的主要敌人之一,特别是当它来自科学和专业领域时。在这个意义上,一些研究人员提出的关于世界卫生组织(WHO)将衰老分类为疾病的建议与健康衰老方法背道而驰。在这个意义上,我们认为没有理论或科学支持将衰老归类为疾病,因此,我们必须在世卫组织面前倡导,以便在其疾病分类代码中消除衰老。在这个框架中,这篇综述提出了“年龄歧视的标志”的概念,被定义为特征,对衰老的拒绝和歧视的表述和态度,老年人和老年人,在政治和体制上,科学或专业,技术和数字,社会,家庭和个人层面,以明确和结构化的方式呈现。出于这个原因,必须全面识别和分析“年龄歧视的标志”,为了提出包括促进“反年龄歧视”的战略和公共政策的方案,作为对“老龄化标志”的反建议,其与衰老相关的生物学变化旨在与慢性非传染性疾病相当。
    Ageism is a type of discrimination characterized by negative social representations of old age and aging, with prejudices and stereotypes that cause rejection and marginalization of older adults, generally considering them as fragile and unproductive. For this reason, it is recognized as one of the main enemies of healthy aging, especially when it arises from the scientific and professional fields. In this sense, the proposals promoted by some researchers regarding the World Health Organization (WHO) classifying aging as a disease goes against the healthy aging approach. In this sense, we consider that there is no theoretical or scientific support to classify aging as a disease, so we must advocate before the WHO so that aging is eliminated within its disease classification codes. In this framework, this review proposes the concept of \"hallmarks of ageism\" defined as the characteristics, representations and attitudes of rejection and discrimination towards aging, old age and older people, at the political and institutional, scientific or professional, technological and digital, social, family and personal levels, which are presented in an articulated and structured manner. For this reason, it is essential to comprehensively identify and analyze the \"hallmarks of ageism\", in order to propose programs that include strategies and public policies that promote \"anti-ageism\" as a counterproposal to the \"hallmarks of aging\", whose biological changes related to aging are intended to be comparable to chronic non-communicable diseases.

    迅速增加的老龄化患病率,复杂性,异质性给科学界和医学界带来了挑战。这些是通过基础研究和转化研究之间的差距来实现的,以及临床实践指南之间,以提高生存率和缺乏证据的个性化策略,以提高功能,幸福和生活质量。衰老科学的成就越来越清楚地揭示了衰老的机制以及医学和技术进步以延长预期寿命的机制。目前,在接下来的二三十年里,生物生物学家和老年病学家之间必须进行更密切的跨学科对话,以使现实生活中对衰老表型的测量能够用来揭示新发现的衰老时钟的生理相关性,从而揭示其转化相关性,生物标志物,和标志。
    The rapidly increasing aging prevalence, complexity, and heterogeneity pose the scientific and medical communities in front of challenges. These are delivered by gaps between basic and translational research, as well as between clinical practice guidelines to improve survival and absence of evidence on personalized strategies to improve functions, wellbeing and quality of life. The triumphs of aging science sheding more and more light on mechanisms of aging as well as those of medical and technological progress to prolong life expectancy are clear. Currently, and in the next two to three decades, all efforts must be put in a closer interdisciplinary dialogue between biogerontologists and geriatricians to enable real-life measures of aging phenotypes to be used to uncover the physiological - and therefore translational - relevance of newly discovered aging clocks, biomarkers, and hallmarks.

    In this narrative review, we sought to provide a comprehensive overview of the mechanisms underlying cutaneous senescence, framed by the twelve traditional hallmarks of aging. These include genomic instability, telomere attrition, epigenetic alterations, loss of proteostasis, impaired macroautophagy, deregulated nutrient sensing, mitochondrial dysfunction, cellular senescence, stem cell exhaustion, altered intercellular communication, chronic inflammation, and dysbiosis. We also examined how topical interventions targeting these hallmarks can be integrated with conventional aesthetic medicine techniques to enhance skin rejuvenation. The potential of combining targeted topical therapies against the aging hallmarks with minimally invasive procedures represents a significant advancement in aesthetic medicine, offering personalized and effective strategies to combat skin aging. The reviewed evidence paves the way for future advancements and underscores the transformative potential of integrating scientifically validated interventions targeted against aging hallmarks into traditional aesthetic practices.

    Ras同源物在脑中富集(Rheb1和Rheb2),小GTPases,在调节神经元活动中发挥关键作用,并因其在癌症发展中的影响而受到关注,特别是在乳腺癌中。这项研究深入研究了Rheb1在神经元和癌症中的多方面功能之间的复杂联系,特别关注mTOR途径。它旨在阐明Rheb1参与关键细胞过程,如增殖,凋亡抗性,迁移,入侵,转移,和炎症反应,同时承认Rheb2尚未被广泛研究。尽管有公认的协会,对Rheb1和Rheb2之间复杂的相互作用以及它们在神经和癌症中的作用的全面理解仍然难以捉摸。这篇综述巩固了关于Rheb1对癌症标志的影响的现有知识,并探讨了Rheb1作为癌症治疗中治疗靶标的潜力。它强调了更深入理解Rheb1介导的致癌过程的分子机制的必要性,强调我们在理解上存在的差距。此外,这篇综述强调了Rheb1抑制剂作为癌症治疗的一个有希望的途径的探索.通过阐明Rheb1/Rheb2与癌症之间的复杂作用,这项研究为科学界提供了有价值的见解。这些见解有助于指导新靶标的识别和推进治疗癌症的有效治疗策略的开发。
    Ras homolog enriched in brain (Rheb1 and Rheb2), small GTPases, play a crucial role in regulating neuronal activity and have gained attention for their implications in cancer development, particularly in breast cancer. This study delves into the intricate connection between the multifaceted functions of Rheb1 in neurons and cancer, with a specific focus on the mTOR pathway. It aims to elucidate Rheb1\'s involvement in pivotal cellular processes such as proliferation, apoptosis resistance, migration, invasion, metastasis, and inflammatory responses while acknowledging that Rheb2 has not been extensively studied. Despite the recognized associations, a comprehensive understanding of the intricate interplay between Rheb1 and Rheb2 and their roles in both nerve and cancer remains elusive. This review consolidates current knowledge regarding the impact of Rheb1 on cancer hallmarks and explores the potential of Rheb1 as a therapeutic target in cancer treatment. It emphasizes the necessity for a deeper comprehension of the molecular mechanisms underlying Rheb1-mediated oncogenic processes, underscoring the existing gaps in our understanding. Additionally, the review highlights the exploration of Rheb1 inhibitors as a promising avenue for cancer therapy. By shedding light on the complicated roles between Rheb1/Rheb2 and cancer, this study provides valuable insights to the scientific community. These insights are instrumental in guiding the identification of novel targets and advancing the development of effective therapeutic strategies for treating cancer.

    周细胞(PC)位于小血管壁周围,特别是毛细血管和微血管。除了维持血管完整性的功能外,参与血管生成,调节血液流动,PC还可以作为白色多能干细胞/祖细胞的储库,棕色,米色,和骨髓脂肪组织。由于这种细胞群的复杂性,PC的识别和表征一直具有挑战性。全面了解PC的异质性可能会增强其作为代谢综合征或骨相关疾病治疗靶标的潜力。这篇小型综述总结了谱系追踪研究中常用的多种PC标记,强调它们在不同代谢条件下对脂肪生成和功能的贡献。
    Pericytes (PCs) are located surrounding the walls of small blood vessels, particularly capillaries and microvessels. In addition to their functions in maintaining vascular integrity, participating in angiogenesis, and regulating blood flow, PCs also serve as a reservoir for multi-potent stem/progenitor cells in white, brown, beige, and bone marrow adipose tissues. Due to the complex nature of this cell population, the identification and characterization of PCs has been challenging. A comprehensive understanding of the heterogeneity of PCs may enhance their potential as therapeutic targets for metabolic syndromes or bone-related diseases. This mini-review summarizes multiple PC markers commonly employed in lineage-tracing studies, with an emphasis on their contribution to adipogenesis and functions in different adipose depots under diverse metabolic conditions.

    在1990年代初期,从B细胞淋巴瘤中反复易位的位点鉴定出一组不相关的基因。尽管共享术语\'Bcl\',与血源性癌症有关,这些基因有不相关的功能。在这些基因中,BCL2被认为是参与胱天蛋白酶和其他细胞生存力机制调节的关键癌症靶标。另一方面,BCL3最初被鉴定为NF-kB转录因子途径的非规范调节因子-一种与重要细胞结果相关的信号机制,包括许多癌症标志。大多数对BCL3功能的早期研究都集中在其在NF-kB介导的细胞增殖中的作用。炎症/免疫和癌症。然而,最近的证据表明,这种蛋白质直接与许多其他信号通路相互作用并调节,包括DNA损伤修复,WNT/β-连环蛋白,AKT,TGFβ/SMAD3和STAT3-所有这些在癌症发展中起关键作用,实体瘤的转移性进展和治疗。在这里,我们回顾了证明BCL3在一系列实体瘤类型中调节癌症生物学和治疗反应的信号通路转录网络中的核心作用的直接证据,并提出了BCL3的共同作用机制,这些机制可能在未来被利用来靶向其致癌效应,以使患者受益。
    In the early 1990\'s a group of unrelated genes were identified from the sites of recurring translocations in B-cell lymphomas. Despite sharing the nomenclature \'Bcl\', and an association with blood-borne cancer, these genes have unrelated functions. Of these genes, BCL2 is best known as a key cancer target involved in the regulation of caspases and other cell viability mechanisms. BCL3 on the other hand was originally identified as a non-canonical regulator of NF-kB transcription factor pathways - a signaling mechanism associated with important cell outcomes including many of the hallmarks of cancer. Most of the early investigations into BCL3 function have since focused on its role in NF-kB mediated cell proliferation, inflammation/immunity and cancer. However, recent evidence is coming to light that this protein directly interacts with and modulates a number of other signaling pathways including DNA damage repair, WNT/β-catenin, AKT, TGFβ/SMAD3 and STAT3 - all of which have key roles in cancer development, metastatic progression and treatment of solid tumours. Here we review the direct evidence demonstrating BCL3\'s central role in a transcriptional network of signaling pathways that modulate cancer biology and treatment response in a range of solid tumour types and propose common mechanisms of action of BCL3 which may be exploited in the future to target its oncogenic effects for patient benefit.
