The concept of addiction, traditionally confined to substances such as drugs and alcohol, has expanded to encompass behavioral patterns such as compulsive eating. Emerging evidence suggests that ultra-processed foods (UPFs), particularly those high in refined sugars and saturated fats, may elicit neurobiological responses akin to those observed in substance use disorders. This review explores the hypothesis that food addiction shares common clinical and neurochemical mechanisms with traditional forms of addiction, drawing from DSM-5 diagnostic criteria and recent findings in neuropharmacology. Animal and human studies have demonstrated that excessive consumption of palatable foods can induce behaviors characteristic of addiction—bingeing, craving, tolerance, and withdrawal—accompanied by significant dopaminergic alterations within the mesolimbic reward circuitry. Neuroimaging and molecular studies further reveal that chronic overconsumption of UPFs alters dopaminergic tone, disrupts prefrontal control, and activates stress pathways, thereby reinforcing compulsive intake. The Yale Food Addiction Scale (YFAS) and its pediatric adaptations provide structured tools for identifying food addiction phenotypes in clinical and research settings. Moreover, parallels between binge eating disorder and substance dependence highlight overlapping neurobehavioral mechanisms. As the obesity epidemic intensifies, particularly among populations with limited access to nutritious foods, understanding the pharmacological underpinnings of food addiction becomes critical. This review underscores the need to reframe UPFs as potentially addictive agents and calls for integrative therapeutic strategies and policy-driven reforms aimed at mitigating their impact on public health.
成瘾的概念,传统上仅限于药物和酒精等物质,已经扩展到包括强迫性饮食等行为模式。新出现的证据表明,超加工食品(upf),特别是那些精制糖和饱和脂肪含量高的食品,可能会引发类似于在物质使用障碍中观察到的神经生物学反应。本文根据DSM-5的诊断标准和神经药理学的最新发现,探讨了食物成瘾与传统形式的成瘾具有共同的临床和神经化学机制的假设。动物和人类研究表明,过度食用美味食物会诱发成瘾行为特征——暴饮暴食、渴望、耐受和戒断——伴随着中脑边缘奖励回路中显著的多巴胺能改变。神经影像学和分子研究进一步表明,长期过量摄入upf会改变多巴胺能张力,破坏前额叶控制,激活应激通路,从而加强强迫性摄入。耶鲁食物成瘾量表(YFAS)及其儿科适应性为临床和研究环境中识别食物成瘾表型提供了结构化工具。此外,暴食症和物质依赖之间的相似之处突出了重叠的神经行为机制。随着肥胖流行病的加剧,特别是在获得营养食物有限的人群中,了解食物成瘾的药理学基础变得至关重要。本综述强调有必要将upf重新定义为潜在的成瘾性药物,并呼吁采取综合治疗策略和政策驱动的改革,以减轻其对公共卫生的影响。

Because of the dysregulation of protein kinase activity in many neoplastic and inflammatory diseases, protein kinases are among the most significant drug targets in the 21st century. Of the 94 FDA-approved protein kinase inhibitors, ten were approved in 2025. Of these drugs, six target dual specificity protein kinases (MEK1/2), fourteen inhibit protein-serine/threonine kinases, twenty-six block nonreceptor protein-tyrosine kinases, and 48 target receptor protein-tyrosine kinases. Most of these drugs (≈ 80) are prescribed for the management of neoplasms and others are used for the treatment of inflammatory and miscellaneous diseases. Of the 94 FDA-approved agents, about two dozen are used in the treatment of multiple diseases. The following ten drugs received FDA approval in 2025 – avutometinib (inhibiting MEK1/2 in serous ovarian carcinomas), defactinib (blocking FAK in low grade serous ovarian carcinomas), delgocitinib (antagonizing the JAK family in hand eczema), mirdametinib (inhibiting MEK1/2 in type I neurofibromatosis), remibrutinib (blocking BTK in chronic spontaneous urticaria), rilzabrutinib (antagonizing BTK in chronic immune thrombocytopenia), sunvozertinib (blocking mutant exon 21 insertion EGFR NSCLC), taletrectinib (inhibiting mutant ROS1 in NSCLC), vimseltinib (blocking CSF1R in tenosynovial giant cell tumors), and zongertinib (antagonizing mutant HER2 in NSCLC). Ninety of the approved protein kinase blockers are orally bioavailable. This article summarizes the physicochemical properties of all 94 FDA-approved small molecule protein kinase inhibitors including the molecular weight, number of hydrogen bond donors/acceptors, ligand efficiency, lipophilic efficiency, polar surface area, and solubility. A total of 45 of the 94 FDA-approved drugs have a least one Lipinski rule of five violation.

Current therapies for immune-mediated diseases often lack precision, causing broad immunosuppression. While Mangifera indica L. extract (here referred to as MIE) shows promise in resolving pain and modulating adaptive immunity, its direct impact on monocyte recruitment and macrophage polarization, remains elusive. Using a reverse translational approach, we examined the effects of MIE on primary human monocytes and macrophages from healthy donors and inflammatory bowel disease (IBD) patients. We assessed its ability to inhibit monocyte transmigration across TNF-α-activated endothelial monolayers and to modulate macrophage polarization along the M1/M2 phenotypes. Transcriptomic profiling via RNA-seq revealed several MIE-responsive pathways in human macrophages, which were subsequently validated functionally using murine peritoneal macrophages stimulated with a panel of distinct toll-like receptors (TLRs) agonists. MIE markedly impaired monocyte adhesion and transmigration across activated endothelium. In human macrophages, it selectively attenuated the pro-inflammatory M1 phenotype, robustly suppressing TNF-α secretion from both healthy donors and IBD patients, while exerting minimal effects on the M2 profile. Transcriptomic analysis revealed that MIE disrupts key inflammatory signalling networks, notably those governed by NF-κB and TLRs. Mechanistically, MIE did not exert broad TLR inhibition but instead acted as a precise immunological rheostat, dampening responses to murine TLR2, TLR4, and TLR6 agonists. TLR4-targeted modulation was mediated via downregulation of MyD88 and NF-κB expression, culminating in reduced pro-inflammatory cytokine production. We delineate a novel mechanism for MIE as a selective rheostat of the TLR2/4/6 axis for restoring innate immune homeostasis in inflammatory-based diseases.
目前免疫介导疾病的治疗方法往往缺乏精确性,导致广泛的免疫抑制。虽然芒果提取物(这里称为MIE)在缓解疼痛和调节适应性免疫方面有希望,但其对单核细胞募集和巨噬细胞极化的直接影响尚不清楚。使用反向翻译方法,我们研究了MIE对来自健康供体和炎症性肠病(IBD)患者的原代人单核细胞和巨噬细胞的影响。我们评估了其抑制单核细胞在TNF-α-活化的内皮单层上的转移和调节巨噬细胞沿M1/M2表型极化的能力。通过RNA-seq转录组分析揭示了人类巨噬细胞的几种mie响应途径,随后使用一系列不同的toll样受体(TLRs)激动剂刺激小鼠腹膜巨噬细胞对其进行了功能验证。MIE明显损害单核细胞在活化内皮中的粘附和迁移。在人巨噬细胞中,它选择性地减弱促炎M1表型,强有力地抑制来自健康供体和IBD患者的TNF-α分泌,同时对M2谱的影响很小。转录组学分析显示,MIE破坏了关键的炎症信号网络,特别是由NF-κB和TLRs控制的信号网络。在机制上,MIE不发挥广泛的TLR抑制作用,而是作为一种精确的免疫变阻器,抑制对小鼠TLR2、TLR4和TLR6激动剂的反应。tlr4靶向调节通过下调MyD88和NF-κB表达介导,最终减少促炎细胞因子的产生。我们描述了一种新的机制,即MIE作为TLR2/4/6轴的选择性变阻器,在炎症性疾病中恢复先天免疫稳态。

Purpose

Herbal medicines are widely used during pregnancy, yet their potential effects on offspring remain uncertain. This systematic review aimed to comprehensively evaluate both the potential benefits and risks of prenatal herbal medicine use on offspring outcomes by synthesizing evidence from randomized controlled trials (RCTs) and observational studies.

Methods

We searched PubMed, Embase, and the Cochrane Central Register of Controlled Trials from inception to November 9, 2024. Eligible studies reported maternal use of herbal medicines during pregnancy and assessed offspring-related outcomes.

Results

A total of 111 studies met the inclusion criteria, comprising 39 RCTs, 36 cohort studies, 18 case–control studies, and 18 cross-sectional surveys. In RCTs, prenatal use of certain herbal medicines was associated the live birth rate (RR=1.14, 95 % CI: 1.05–1.24) and a lower risk of birth defects (RR=0.46, 95 % CI: 0.22–0.94), primarily among women undergoing assisted reproduction; reductions in miscarriage were observed among those with threatened or recurrent miscarriage. At the overall level, observational studies adjusted for confounding did not show significant associations between prenatal herbal medicine use and major adverse offspring outcomes (including birth defects, miscarriage, stillbirth, or preterm birth). Exploratory analyses of individual herbal products suggested that some specific herbs—such as almond oil and Glycyrrhiza (with preterm birth), betel quid (with low birth weight), An-Tai-Yin (with musculoskeletal malformations), khat (with nervous system malformations), and Coptidis Rhizoma (with nervous system and genital organ malformations)—may be linked to increased risks. However, these signals were based on a limited number of studies and should be interpreted with caution given variability in exposure definitions, study quality, and potential residual confounding.

Conclusions

For women undergoing assisted reproduction or those at increased risk of miscarriage, certain herbal medicines may offer potential benefits during pregnancy. Overall, evidence from RCTs and adjusted observational studies does not indicate a clear increase in adverse offspring outcomes associated with prenatal herbal medicine use. Nonetheless, a few herbs have been linked to potential safety concerns, although the supporting evidence remains limited and heterogeneous. Cautious use is advised, particularly for products without robust data on fetal and long-term postnatal safety.
目的:草药在怀孕期间被广泛使用,但它们对后代的潜在影响仍不确定。本系统综述旨在综合随机对照试验(rct)和观察性研究的证据,全面评估产前使用草药对后代结局的潜在益处和风险。方法:检索PubMed、Embase和Cochrane中央对照试验注册库(Central Register of Controlled Trials),检索时间从成立到2024年11月9日。符合条件的研究报告了母亲在怀孕期间使用草药的情况,并评估了与后代相关的结果。结果:共有111项研究符合纳入标准,包括39项随机对照研究、36项队列研究、18项病例对照研究和18项横断面调查。在随机对照试验中,产前使用某些草药与活产率(RR=1.14, 95% CI: 1.05-1.24)和较低的出生缺陷风险(RR=0.46, 95% CI: 0.22-0.94)相关,主要是在接受辅助生殖的妇女中;流产的减少被观察到在那些有先兆或复发性流产。总体而言,经混杂因素调整后的观察性研究并未显示出产前使用草药与主要不良后代结局(包括出生缺陷、流产、死胎或早产)之间存在显著关联。个别草药产品的探索性分析表明,一些特定的草药——如杏仁油和甘草(早产)、槟榔液(低出生体重)、安泰饮(肌肉骨骼畸形)、阿拉伯茶(神经系统畸形)和黄连(神经系统和生殖器官畸形)——可能与风险增加有关。然而,这些信号是基于有限数量的研究,考虑到暴露定义、研究质量和潜在残留混淆的可变性,应谨慎解释。结论:对于接受辅助生殖或流产风险增加的妇女,某些草药可能在怀孕期间提供潜在的益处。总的来说,来自随机对照试验和调整后的观察性研究的证据并没有表明与产前使用草药相关的不良后代结局明显增加。尽管如此,一些草药与潜在的安全问题有关,尽管支持的证据仍然有限且不同。建议谨慎使用,特别是对于没有胎儿和产后长期安全性可靠数据的产品。

YBX1-LDHB axis orchestrates pyruvate production from lactate to promote ICC initiation and development YBX1-LDHB轴协调乳酸生成丙酮酸,促进ICC的发生和发展

Previous work from our group established that Y-box binding protein 1 (YBX1) plays a pivotal role in the initiation and progression of intrahepatic cholangiocarcinoma (ICC); however, its specific biological functions and underlying regulatory mechanisms remain unclear. The current study demonstrates that YBX1 is highly expressed in ICC tissues, and its highly expression correlates significantly with a poor prognosis in patients with ICC. In vitro experiments revealed that YBX1 overexpression significantly enhanced the proliferation of ICC cells. Conversely, YBX1 knockout robustly inhibited tumor growth in both in vitro and in vivo models. Mechanistically, YBX1 upregulated the expression of lactate dehydrogenase B (LDHB) by increasing its transcriptional activity and stabilizing LDHB mRNA. Elevated LDHB expression drives the conversion of lactate to pyruvate, which is further metabolized to acetyl coenzyme A. This metabolic reprogramming enhances the activity of tricarboxylic acid (TCA) cycle and production of adenosine triphosphate, thereby providing essential energy support for the proliferation of ICC cells. Corroboratively, inhibiting LDHB via CRISPR-Cas9-mediated knockout suppressed ICC cell proliferation, whereas LDHB overexpression accelerated the ICC tumor progression.

本小组前期工作证实,Y-box结合蛋白1 (YBX1)在肝内胆管癌(ICC)的发生和发展中起关键作用;然而,其具体的生物学功能和潜在的调控机制尚不清楚。本研究表明YBX1在ICC组织中高表达,其高表达与ICC患者预后不良显著相关。体外实验表明,YBX1过表达可显著促进ICC细胞的增殖。相反,在体外和体内模型中,YBX1敲除均能显著抑制肿瘤生长。在机制上,YBX1通过增加乳酸脱氢酶B (LDHB)的转录活性和稳定LDHB mRNA来上调其表达。升高的LDHB表达驱动乳酸转化为丙酮酸,丙酮酸进一步代谢为乙酰辅酶a。这种代谢重编程增强了三羧酸(TCA)循环的活性和三磷酸腺苷的产生,从而为ICC细胞的增殖提供必需的能量支持。证实,通过crispr - cas9介导的敲除抑制LDHB抑制ICC细胞增殖,而LDHB过表达加速ICC肿瘤进展。乳酸诱导YBX1核易位,进而激活LDHB转录。总之,我们的研究结果证明了YBX1和LDHB在ICC进展中的致癌作用,确定了乳酸是维持TCA循环和氧化磷酸化活性的关键能量来源,并强调了YBX1-LDHB轴是潜在的治疗靶点。

Neurodegenerative diseases impose a heavy social and economic burden, and effective therapeutic strategies are essential for slowing disease progression and improving patient quality of life. Notoginsenoside R1 (NGR1), a key saponin derived from Panax notoginseng (Burk. F.H. Chen), has been widely studied in experimental models of neurodegenerative diseases, such as stroke and Alzheimer’s disease (AD). Based on a rigorous literature screening and a meta-analysis of animal studies, we confirmed that NGR1 significantly reduces infarct volumes in cerebral ischemia-reperfusion models and improves escape latency in AD mice. Mechanistically, NGR1 confers neuroprotection by attenuating oxidative stress, suppressing neuroinflammation, inhibiting apoptosis, and preserving the neurovascular unit. Furthermore, using network pharmacology, reverse virtual screening, and molecular docking, we preliminarily identified potential targets and signaling pathways, providing a theoretical basis for future studies. However, clinical translation of NGR1 remains limited due to poor oral bioavailability and restricted permeability across the blood-brain and blood-spinal cord barriers. To address these challenges, we summarized delivery strategies, including nanoparticle-based carriers, intranasal administration, and permeability enhancers, to facilitate NGR1 entry into the central nervous system. We also discussed additional potential approaches, such as structural modification and targeted delivery, analyzing their respective advantages and limitations. Collectively, these findings highlight NGR1 as a promising candidate for the prevention and treatment of neurodegenerative diseases.
神经退行性疾病造成沉重的社会和经济负担,有效的治疗策略对于减缓疾病进展和改善患者生活质量至关重要。三七皂苷R1 (NGR1)是一种从三七中提取的关键皂苷。在神经退行性疾病,如中风和阿尔茨海默病(AD)的实验模型中得到了广泛的研究。基于严格的文献筛选和动物研究的荟萃分析,我们证实NGR1显著减少脑缺血再灌注模型中的梗死体积,并改善AD小鼠的逃避潜伏期。从机制上讲,NGR1通过减轻氧化应激、抑制神经炎症、抑制细胞凋亡和保存神经血管单位来提供神经保护。通过网络药理学、反向虚拟筛选、分子对接等手段,初步确定了潜在靶点和信号通路,为后续研究提供理论基础。然而,由于口服生物利用度差以及血脑和血脊髓屏障的渗透性有限,NGR1的临床转化仍然有限。为了解决这些挑战,我们总结了递送策略,包括纳米颗粒载体、鼻内给药和渗透性增强剂,以促进NGR1进入中枢神经系统。我们还讨论了其他可能的方法,如结构改造和定向输送,分析了各自的优势和局限性。总的来说,这些发现突出了NGR1作为预防和治疗神经退行性疾病的有希望的候选者。

Recurrence of high-risk advanced retinoblastoma (RB) is still a major obstacle even after enucleation due to resistance to adjuvant chemotherapy, especially in China. To identify any germline alterations or candidate genes associated with RB prognosis, we obtained whole-exome sequencing (WES) and reduced-representation bisulfite sequencing (RRBS) profiles by using patient peripheral blood samples, followed by clinical validation and functional characterization. For follow-up studies, we selected 17 candidate genes from the WES and RRBS analyses. Among them, MBD4, which carries a germline loss-of-function mutation (rs140693), was identified for further clinical replication. MBD4 downregulation significantly impaired carboplatin or etoposide efficacy in vitro and in vivo, respectively. There were marked decreases in the expression of 5 related genes plus increased DNA methylation in their promoters in Y79 (MBD4-/-) cells, along with even more significant effects after carboplatin treatment. MBD4 affected the transcription and expression of its downstream genes, such as FADD and P21, via MBDCap-PCR, ChIPqPCR, and reporter gene assays. Moreover, the germline mutation was responsible for MBD4 instability with attenuated binding to USP7, thereby leading to impaired drug sensitivity. It was confirmed by the reinstated susceptibility of Y79 (MBD4-/-) cells after MBD4-WT was restored. In the present study, our findings indicate that depletion or mutation of MBD4 interferes with the activation of the cell cycle and apoptosis via epigenetic regulation, thereby reducing drug susceptibility. It provides new insights into the role in RB chemoresistance of MBD4 as an epigenetic regulator, which might fuel the development of new RB-targeted strategies.
高风险晚期视网膜母细胞瘤(RB)即使在去核后,由于对辅助化疗的耐药性,复发仍然是一个主要障碍,特别是在中国。为了确定任何与RB预后相关的生殖系改变或候选基因,我们通过使用患者外周血样本获得了全外显子组测序(WES)和减少代表性亚硫酸酯测序(RRBS)谱,随后进行了临床验证和功能表征。在后续研究中,我们从WES和RRBS分析中选择了17个候选基因。其中,携带生殖系功能缺失突变(rs140693)的MBD4被确定用于进一步的临床复制。MBD4下调在体外和体内分别显著损害卡铂或依托泊苷的疗效。在Y79 (MBD4-/-)细胞中,5个相关基因的表达显著降低,其启动子DNA甲基化增加,卡铂治疗后效果更为显著。通过MBDCap-PCR、ChIPqPCR和报告基因检测,MBD4影响其下游基因FADD和P21的转录和表达。此外,种系突变导致MBD4不稳定,与USP7的结合减弱,从而导致药物敏感性受损。在恢复MBD4- wt后,Y79 (MBD4-/-)细胞恢复了敏感性,证实了这一点。在本研究中,我们的研究结果表明,MBD4的缺失或突变通过表观遗传调控干扰细胞周期和凋亡的激活,从而降低药物敏感性。它为MBD4作为表观遗传调控因子在RB化疗耐药中的作用提供了新的见解,这可能推动新的RB靶向策略的发展。
