    癌症是世界范围内导致死亡的主要原因之一,每年有超过1000万人死亡。虽然肿瘤可以手术切除并用化疗治疗,放射治疗,免疫疗法,激素治疗,或联合疗法,目前的治疗通常会导致正常组织的毒副作用。因此,研究人员正在积极寻找选择性消除癌细胞的方法,将正常组织的毒副作用降至最低。酪蛋白及其衍生物已显示出有希望的抗癌潜力,证明抗肿瘤和细胞毒性作用,从各种肿瘤类型的细胞不造成伤害正常细胞。总的来说,这些数据揭示了酪蛋白及其衍生肽研究的进展,特别是提供对癌症治疗中作用的分子机制的全面了解。这些机制通过各种信号通路发生,包括(i)干扰素相关STAT1信号的增加,(ii)抑制干性相关标志物,如CD44,(iii)衰减STAT3/HIF1-α信号,(iv)uPAR和PAI-1的下调表达,(v)线粒体膜电位的丧失和细胞内ATP产生的减少,(vi)caspase-3活性的增加,和(vii)TLR4/NF-κB信号传导的抑制。因此,我们得出的结论是酪蛋白可能是癌症治疗的有效佐剂。
    Cancer is one of the leading causes of death worldwide, with over 10 million fatalities annually. While tumors can be surgically removed and treated with chemotherapy, radiotherapy, immunotherapy, hormonal therapy, or combined therapies, current treatments often result in toxic side effects in normal tissue. Therefore, researchers are actively seeking ways to selectively eliminate cancerous cells, minimizing the toxic side effects in normal tissue. Caseins and its derivatives have shown promising anti-cancer potential, demonstrating antitumor and cytotoxic effects on cells from various tumor types without causing harm to normal cells. Collectively, these data reveals advancements in the study of caseins and their derivative peptides, particularly providing a comprehensive understanding of the molecular mechanism of action in cancer therapy. These mechanisms occur through various signaling pathways, including (i) the increase of interferon-associated STAT1 signaling, (ii) the suppression of stemness-related markers such as CD44, (iii) the attenuation of the STAT3/HIF1-α signaling, (iv) the down-expression of uPAR and PAI-1, (v) the loss of mitochondrial membrane potential and reduced intracellular ATP production, (vi) the increase of caspase-3 activity, and (vii) the suppression of TLR4/NF-кB signaling. Therefore, we conclude that casein could be an effective adjuvant for cancer treatment.

    Addressing the need for more equitable cardio-oncology care requires attention to existing disparities in cardio-oncologic disease prevention and outcomes. This is particularly important among those affected by adverse social determinants of health (SDOH). The intricate relationship of SDOH, cancer diagnosis, and outcomes from cardiotoxicities associated with oncologic therapies is influenced by sociopolitical, economic, and cultural factors. Furthermore, mechanisms in cell signaling and epigenetic effects on gene expression link adverse SDOH to cancer and the CVD-related complications of oncologic therapies. To mitigate these disparities, a multifaceted strategy is needed that includes attention to health care access, policy, and community engagement for improved disease screening and management. Interdisciplinary teams must also promote cultural humility and competency and leverage new health technology to foster collaboration in addressing the impact of adverse SDOH in cardio-oncologic outcomes.

    多发性骨髓瘤(MM)是第二常见的浆细胞恶性血液病,以溶骨性骨病变为特征,贫血,高钙血症,肾功能衰竭,和恶性浆细胞的积累。MM的发病机制涉及MM细胞通过可溶性细胞因子和细胞粘附分子与骨髓微环境相互作用,激活各种信号通路,如PI3K/AKT/mTOR,RAS/MAPK,JAK/STAT,Wnt/β-catenin,和NF-κB通路。这些途径的异常激活有助于增殖,生存,迁移,和骨髓瘤细胞的耐药性,使它们成为有吸引力的治疗干预目标。目前,在MM中针对这些信号通路的批准药物是有限的,许多抑制剂和诱导剂仍处于临床前或临床研究阶段。MM的治疗选择包括非靶向药物,如烷化剂,皮质类固醇,免疫调节药物,蛋白酶体抑制剂,和组蛋白脱乙酰酶抑制剂。此外,靶向药物如单克隆抗体,嵌合抗原受体T细胞,双特异性T细胞衔接者,和双特异性抗体正在用于MM治疗。尽管在MM治疗方面取得了重大进展,这种疾病仍然无法治愈,强调需要根据新兴的理论知识开发新的或联合的靶向疗法,技术,和平台。在这次审查中,我们强调了信号通路在MM的恶性进展和治疗中的关键作用,探索靶向治疗和潜在治疗的进展,为改善MM管理和结局提供进一步的见解。
    Multiple myeloma (MM) is the second most common hematological malignancy of plasma cells, characterized by osteolytic bone lesions, anemia, hypercalcemia, renal failure, and the accumulation of malignant plasma cells. The pathogenesis of MM involves the interaction between MM cells and the bone marrow microenvironment through soluble cytokines and cell adhesion molecules, which activate various signaling pathways such as PI3K/AKT/mTOR, RAS/MAPK, JAK/STAT, Wnt/β-catenin, and NF-κB pathways. Aberrant activation of these pathways contributes to the proliferation, survival, migration, and drug resistance of myeloma cells, making them attractive targets for therapeutic intervention. Currently, approved drugs targeting these signaling pathways in MM are limited, with many inhibitors and inducers still in preclinical or clinical research stages. Therapeutic options for MM include non-targeted drugs like alkylating agents, corticosteroids, immunomodulatory drugs, proteasome inhibitors, and histone deacetylase inhibitors. Additionally, targeted drugs such as monoclonal antibodies, chimeric antigen receptor T cells, bispecific T-cell engagers, and bispecific antibodies are being used in MM treatment. Despite significant advancements in MM treatment, the disease remains incurable, emphasizing the need for the development of novel or combined targeted therapies based on emerging theoretical knowledge, technologies, and platforms. In this review, we highlight the key role of signaling pathways in the malignant progression and treatment of MM, exploring advances in targeted therapy and potential treatments to offer further insights for improving MM management and outcomes.

    肿瘤异质性在骨肉瘤(OS)治疗中提出了重大挑战。在这方面,“组学”时代不断扩大我们对生物标志物和改变的信号通路的理解(即,PI3K/AKT/mTOR,WNT/β-连环蛋白,NOTCH,SHH/GLI,其中)涉及OS病理生理学。尽管参与者和复杂性不同,已经描述了许多共性,其中核因子κB(NF-κB)脱颖而出。它的激活改变在癌症中普遍存在,对许多疾病相关性状具有多效性作用。因此,在本文的范围内,我们强调了OS中NF-κB失调及其与其他癌症相关途径整合的证据,同时我们总结了已被描述为干扰其作用的化合物库.使用计算机策略来证明NF-κB与其他通常失调的信号传导途径紧密协调,不仅通过与其几个成员的功能相互作用,而且通过积极参与其转录的调节。虽然现有的抑制剂缺乏选择性或间接作用,靶向NF-κB的治疗潜力是无可争辩的,首先是它在大多数癌症标志上的多功能性,其次,因为,作为影响OS侵袭性的许多失调途径的常见下游效应物,它将复杂的调控网络转变为分子异质性下的更简单的画面。
    Tumor heterogeneity poses a significant challenge in osteosarcoma (OS) treatment. In this regard, the \"omics\" era has constantly expanded our understanding of biomarkers and altered signaling pathways (i.e., PI3K/AKT/mTOR, WNT/β-catenin, NOTCH, SHH/GLI, among others) involved in OS pathophysiology. Despite different players and complexities, many commonalities have been described, among which the nuclear factor kappa B (NF-κB) stands out. Its altered activation is pervasive in cancer, with pleiotropic action on many disease-relevant traits. Thus, in the scope of this article, we highlight the evidence of NF-κB dysregulation in OS and its integration with other cancer-related pathways while we summarize the repertoire of compounds that have been described to interfere with its action. In silico strategies were used to demonstrate that NF-κB is closely coordinated with other commonly dysregulated signaling pathways not only by functionally interacting with several of their members but also by actively participating in the regulation of their transcription. While existing inhibitors lack selectivity or act indirectly, the therapeutic potential of targeting NF-κB is indisputable, first for its multifunctionality on most cancer hallmarks, and secondly, because, as a common downstream effector of the many dysregulated pathways influencing OS aggressiveness, it turns complex regulatory networks into a simpler picture underneath molecular heterogeneity.

    胚胎干细胞(ESC)是明显未分化的细胞,起源于胚泡的内部细胞团。它们具有自我更新和分化成多种细胞类型的能力,使它们在疾病建模和转基因动物的创造等多种应用中具有不可估量的价值。近年来,随着农业实践从传统育种发展到生物育种,很明显,多能干细胞(PSC),ESC或诱导多能干细胞(iPSC),是连续筛选合适的细胞材料的最佳选择。然而,家畜长期体外培养或建立PSC细胞系的技术还不成熟,研究进展参差不齐,这对PSC在各个领域的应用提出了挑战。这些细胞的强大体外系统的建立关键取决于了解其多能性维持机制。认为多能转录因子的联合作用,关键信号通路,表观遗传调控有助于维持它们的多能状态,形成一个全面的监管网络。本文将深入研究PSC多能性维持的主要机制,并详细阐述PSC在家畜领域的应用。
    Embryonic stem cells (ESCs) are remarkably undifferentiated cells that originate from the inner cell mass of the blastocyst. They possess the ability to self-renew and differentiate into multiple cell types, making them invaluable in diverse applications such as disease modeling and the creation of transgenic animals. In recent years, as agricultural practices have evolved from traditional to biological breeding, it has become clear that pluripotent stem cells (PSCs), either ESCs or induced pluripotent stem cells (iPSCs), are optimal for continually screening suitable cellular materials. However, the technologies for long-term in vitro culture or establishment of cell lines for PSCs in livestock are still immature, and research progress is uneven, which poses challenges for the application of PSCs in various fields. The establishment of a robust in vitro system for these cells is critically dependent on understanding their pluripotency maintenance mechanisms. It is believed that the combined effects of pluripotent transcription factors, pivotal signaling pathways, and epigenetic regulation contribute to maintaining their pluripotent state, forming a comprehensive regulatory network. This article will delve into the primary mechanisms underlying the maintenance of pluripotency in PSCs and elaborate on the applications of PSCs in the field of livestock.

    Pericytes are multipotent cells embedded within the vascular system, primarily surrounding capillaries and microvessels where they closely interact with endothelial cells. These cells are known for their intriguing properties due to their heterogeneity in tissue distribution, origin, and multifunctional capabilities. Specifically, pericytes are essential in regulating blood flow, promoting angiogenesis, and supporting tissue homeostasis and regeneration. These multifaceted roles draw on pericytes\' remarkable ability to respond to biochemical cues, interact with neighboring cells, and adapt to changing environmental conditions. This review aims to summarize existing knowledge on pericytes, emphasizing their versatility and involvement in vascular integrity and tissue health. In particular, a comprehensive view of the major signaling pathways, such as PDGFβ/ PDGFRβ, TGF-β, FOXO and VEGF, along with their downstream targets, which coordinate the behavior of pericytes in preserving vascular integrity and promoting tissue regeneration, will be discussed. In this light, a deeper understanding of the complex signaling networks defining the phenotype of pericytes in healthy tissues is crucial for the development of targeted therapies in vascular and degenerative diseases.

    TAFRO(血小板减少症(T),anasarca(A),发烧(F),网织蛋白纤维化(F/R),肾功能衰竭(R),和器官肿大(O))是特发性多中心Castleman病(iMCD)的异质性临床亚型,与iMCD的其他亚型相比,其预后明显较差。TAFRO症状学也可以在iMCD之外的病理环境中看到,但目前还不清楚这些病例是否应该被认为是代表不同的疾病实体,或者仅仅是其他传染病的严重表现,恶性,和风湿病。虽然白细胞介素-6(IL-6)是iMCD-TAFRO发病机制的既定驱动因素,病因不明。最近关于TAFRO患者的病例报道和文献综述提示血管内皮生长因子(VEGF),以及VEGF和IL-6的相互作用,而不是作为单一细胞因子的IL-6,可能是iMCD-TAFRO病理生理学的驱动程序,尤其是肾损伤。在这次审查中,我们讨论了VEGF在iMCD-TAFRO的病理生理和临床表现中的可能作用。特别是,VEGF可能通过其激活RAS/RAF/MEK/ERK和PI3K/AKT/mTOR信号通路的能力参与iMCD-TAFRO病理。进一步阐明VEGF-IL-6轴的作用和其他疾病驱动因素可能会阐明治疗TAFRO患者的治疗选择,或以其他方式复发,用IL-6靶向药物治疗。本文综述了VEGF在iMCD-TAFRO病理生理学中的潜在作用以及未来靶向相关信号通路的潜力。
    TAFRO (thrombocytopenia (T), anasarca (A), fever (F), reticulin fibrosis (F/R), renal failure (R), and organomegaly (O)) is a heterogeneous clinical subtype of idiopathic multicentric Castleman disease (iMCD) associated with a significantly poorer prognosis than other subtypes of iMCD. TAFRO symptomatology can also be seen in pathological contexts outside of iMCD, but it is unclear if those cases should be considered representative of a different disease entity or simply a severe presentation of other infectious, malignant, and rheumatological diseases. While interleukin-6 (IL-6) is an established driver of iMCD-TAFRO pathogenesis in a subset of patients, the etiology is unknown. Recent case reports and literature reviews on TAFRO patients suggest that vascular endothelial growth factor (VEGF), and the interplay of VEGF and IL-6 in concert, rather than IL-6 as a single cytokine, may be drivers for iMCD-TAFRO pathophysiology, especially renal injury. In this review, we discuss the possible role of VEGF in the pathophysiology and clinical manifestations of iMCD-TAFRO. In particular, VEGF may be involved in iMCD-TAFRO pathology through its ability to activate RAS/RAF/MEK/ERK and PI3K/AKT/mTOR signaling pathways. Further elucidating a role for the VEGF-IL-6 axis and additional disease drivers may shed light on therapeutic options for the treatment of TAFRO patients who do not respond to, or otherwise relapse following, treatment with IL-6 targeting drugs. This review investigates the potential role of VEGF in the pathophysiology of iMCD-TAFRO and the potential for targeting related signaling pathways in the future.

    三阴性乳腺癌(TNBC)细胞缺乏雌激素受体(ER),孕激素受体(PRs),和人表皮生长因子受体2(HER2),它(TNBC)占所有乳腺癌的10-15%。TNBC是高度侵入性的,具有更快的生长速度和更高的转移和复发风险。尽管如此,化疗是治疗TNBC的广泛应用选择之一.本研究综述了TNBC亚型的组织学和分子特征,异常表达的信号通路,靶向这些途径的小分子,作为单一药物或与其他治疗剂如化疗剂的组合,免疫治疗,和抗体-药物缀合物;它们的作用机制,挑战,并回顾了未来的前景。使用从SciFinder收集的文献进行了详细的分析审查,PubMed,ScienceDirect,谷歌学者,ACS,Springer,Wiley数据库发现几种小分子抑制剂是治疗TNBC的治疗剂。研究了小分子的作用机制和发挥其作用的不同信号通路,包括临床试验,如果报告。这些小分子抑制剂包括布帕利西,依维莫司,Vandetanib,阿帕替尼,奥拉帕利,红景天苷,等。参与TNBC的一些信号通路,包括VEGF,PARP,STAT3,MAPK,EGFR,P13K,和SRC路径,进行了讨论。由于缺乏这些生物标志物,治疗TNBC的药物开发具有挑战性,化疗是主要的治疗药物。然而,化疗与化疗耐药性和对健康细胞的高毒性有关。因此,对于特异性靶向在TNBC中异常表达的几种信号通路的小分子抑制剂存在持续的需求。我们试图包括该领域的所有最新发展。任何遗漏都是无意的。
    Triple-negative breast cancer (TNBC) cells are devoid of estrogen receptors (ERs), progesterone receptor (PRs), and human epidermal growth factor receptor 2 (HER2), and it (TNBC) counts for about 10-15% of all breast cancers. TNBC is highly invasive, having a faster growth rate and a higher risk of metastasis and recurrence. Still, chemotherapy is one of the widely used options for treating TNBC. This study reviewed the histological and molecular characterization of TNBC subtypes, signaling pathways that are aberrantly expressed, and small molecules targeting these pathways, as either single agents or in combination with other therapeutic agents like chemotherapeutics, immunotherapeutics, and antibody-drug conjugates; their mechanisms of action, challenges, and future perspectives were also reviewed. A detailed analytical review was carried out using the literature collected from the SciFinder, PubMed, ScienceDirect, Google Scholar, ACS, Springer, and Wiley databases. Several small molecule inhibitors were found to be therapeutics for treating TNBC. The mechanism of action and the different signaling pathways through which the small molecules exert their effects were studied, including clinical trials, if reported. These small molecule inhibitors include buparlisib, everolimus, vandetanib, apatinib, olaparib, salidroside, etc. Some of the signaling pathways involved in TNBC, including the VEGF, PARP, STAT3, MAPK, EGFR, P13K, and SRC pathways, were discussed. Due to the absence of these biomarkers, drug development for treating TNBC is challenging, with chemotherapy being the main therapeutic agent. However, chemotherapy is associated with chemoresistance and a high toxicity to healthy cells as side effects. Hence, there is a continuous demand for small-molecule inhibitors that specifically target several signaling pathways that are abnormally expressed in TNBC. We attempted to include all the recent developments in this field. Any omission is truly unintentional.
