We have previously shown that testosterone depletion in adult male mice induced neural androgen receptor (Ar) down-regulation and led to neuroinflammation and increased blood brain barrier (BBB) permeability in the medial preoptic area. In the present study, we investigated the effects of neural Ar deletion on glial function and BBB integrity in male mice. For this purpose, we used control and mutant littermates obtained from a mouse line deleted for the Ar in neural progenitors by Cre-loxP technology. Neural Ar deletion induced glial activation evidenced by increased immunoreactivity against markers of astrocytes (glial fibrillary acidic protein -GFAP- and N-myc downstream-regulated gene 2) and microglia (ionized calcium binding adaptor molecule 1). Fluoro-Jade® C fluorescent labeling was increased and inflammatory molecules such as inducible nitric oxide synthase (iNOS) and cyclooxygenase 2 (COX2) were detected in the vicinity of capillaries in the male medial preoptic area of neural Ar knockout mice. Analysis of BBB integrity showed enhanced permeability for Evans Blue tracer and endogenous immunoglobulins in mutant animals compared to their control littermates. In addition, modifications in the ultrastructural organization of capillary endothelial tight junctions were observed by electron tomography. These effects were specific to neural Ar deletion since no changes were observed for GFAP-immunoreactivity, BBB permeability or Fluoro-Jade® C labeling in male mice expressing the wild type Ar allele and carrying the Cre transgene.
Altogether, these data indicate the key role of the neural AR in testosterone-induced regulation of astrocyte, microglial and BBB functions in the medial preoptic area of male mice.
我们之前的研究表明,成年雄性小鼠的睾酮消耗诱导神经雄激素受体(Ar)下调,导致神经炎症和内侧视前区血脑屏障(BBB)通透性增加。在本研究中,我们研究了神经Ar缺失对雄性小鼠神经胶质功能和血脑屏障完整性的影响。为此,我们使用了通过Cre-loxP技术从神经祖细胞中删除Ar的小鼠系中获得的对照和突变幼崽。神经Ar缺失诱导胶质细胞活化,这可以通过增强对星形胶质细胞(胶质纤维酸性蛋白- gfap -和N-myc下游调控基因2)和小胶质细胞(离子钙结合接头分子1)标记物的免疫反应性来证明。Fluoro-Jade®C荧光标记增强,在雄性神经Ar敲除小鼠内侧视前区毛细血管附近检测到诱导型一氧化氮合酶(iNOS)和环氧化酶2 (COX2)等炎症分子。血脑屏障完整性分析显示,与对照组相比,突变动物的Evans Blue示踪剂和内源性免疫球蛋白的渗透性增强。此外,通过电子断层扫描观察到毛细血管内皮紧密连接的超微结构组织的变化。这些影响是神经Ar缺失所特有的,因为在表达野生型Ar等位基因并携带Cre转基因的雄性小鼠中,没有观察到gfap免疫反应性、血脑屏障通透性或Fluoro-Jade®C标记的变化。总之,这些数据表明,神经AR在睾丸激素诱导的雄性小鼠内侧视前区星形胶质细胞、小胶质细胞和血脑屏障功能的调节中起关键作用。

Type 2 diabetes mellitus (T2DM) often induces diabetic osteoporosis (DOP) with impaired bone remodeling, yet its underlying mechanism remains elusive. This study identified the differential regulatory role of the AMPK/mTOR/p70 S6K signaling axis in bone cell function. In vivo, diabetes reduced AMPK phosphorylation, enhanced mTOR/p70 S6K activation, and diminished autophagy in rat femoral tissue. In vitro, HG exerted cell-type-specific effects via the AMPK signaling pathway: in osteoblasts, HG inhibited AMPK phosphorylation, activated mTOR/p70 S6K, suppressed autophagy, and impaired mineralization as well as alkaline phosphatase (ALP) activity; conversely, in osteoclasts, HG enhanced autophagy through the inverse regulatory pathway and accelerated osteoclast differentiation and bone resorption. Collectively, these findings illustrate that hyperglycemia disrupts bone homeostasis via cell-type-specific regulation of AMPK, suggesting that AMPK-mediated autophagy serves as a potential critical therapeutic target for diabetes-related bone diseases.
2型糖尿病(T2DM)常诱发糖尿病性骨质疏松症(DOP)并伴骨重塑受损,但其潜在机制尚不清楚。本研究确定了AMPK/mTOR/p70 S6K信号轴在骨细胞功能中的差异调节作用。在体内,糖尿病降低了AMPK的磷酸化,增强了mTOR/p70 S6K的激活,减少了大鼠股组织的自噬。在体外,HG通过AMPK信号通路发挥细胞类型特异性作用:在成骨细胞中,HG抑制AMPK磷酸化,激活mTOR/p70 S6K,抑制自噬,损害矿化和碱性磷酸酶(ALP)活性;相反,在破骨细胞中,HG通过逆调控途径增强自噬,加速破骨细胞分化和骨吸收。总之,这些发现表明,高血糖通过细胞类型特异性调节AMPK破坏骨稳态,表明AMPK介导的自噬是糖尿病相关骨病的潜在关键治疗靶点。

Pursuant to patient desires of alternatives to injectable gonadotropins, a plethora of attempts have identified, characterized, and demonstrated efficacy of small molecules that activate (agonists) gonadotropin receptors. Discoveries have also been made of small molecule gonadotropin receptor inhibitors (antagonists), which have potential as useful alternatives to steroid hormone-based contraception. Implementation of these small molecules in advanced testing systems not necessarily used in screening, which identified lead compounds, has yielded a bounty of wonders. It is likely that a richer understanding of the role of signaling platforms and conformation-dependent molecular assemblies are likely to emerge. Several small molecule agonists have been observed to function as conformational boosters that can rescue receptor trafficking defects, or initiate internalization of receptors without bound hormone. Still others have revealed insights into the role of molecular platforms in persistent signaling. Unexpectedly, such antagonists, like molecular scalpels, can ablate certain signaling pathways and not others leading to discovery of biased signaling in gonadotropin receptors. That seminal observation has led to studies of nuanced signaling and, consequently, nuanced gene expression. Gonadotropin receptor structure-based design for better specificity and potency of agonists and antagonists has been provided by new cryo-EM structures of the gonadotropin receptors, demonstrating proof of concept. Structural determination of downstream supramolecular assemblies will be necessary to validate and fully understand these complicated receptors and how their interaction with other proteins and when occupied by hormone and allosteric modulators, nuances their actions and, ultimately, fertility.

根据患者对可注射性促性腺激素替代品的渴望,大量的尝试已经确定、表征并证明了激活(激动剂)促性腺激素受体的小分子的功效。小分子促性腺激素受体抑制剂(拮抗剂)也有了新发现,有可能成为类固醇激素避孕的有用替代品。将这些小分子应用于不一定用于筛选的先进测试系统中,从而识别出先导化合物,已经产生了大量的奇迹。很可能会对信号平台和构象依赖的分子组装的作用有更丰富的理解。一些小分子激动剂已经被观察到作为构象助推器的功能,可以挽救受体运输缺陷,或启动没有结合激素的受体内化。还有一些人揭示了分子平台在持续信号传导中的作用。出乎意料的是,这些拮抗剂,如分子手术刀,可以消融某些信号通路,而不是其他的,从而发现促性腺激素受体的偏倚信号。这一开创性的观察导致了对细微信号的研究,从而导致了细微的基因表达。基于促性腺激素受体结构的设计为激动剂和拮抗剂更好的特异性和效力提供了新的促性腺激素受体冷冻电镜结构,证明了概念的证明。下游超分子组装的结构确定对于验证和充分理解这些复杂的受体是必要的,以及它们如何与其他蛋白质相互作用,以及当它们被激素和变构调节剂占据时,它们的行为和最终的生育能力是微妙的。

Consumers' risky eating behaviours aided by the current food environment have led to an increase in diet-related metabolic disorders. Metabolic (dysfunction)-associated fatty liver disease origin represents a major global health burden that is increasing at an alarming rate on an annual basis. Modifying the timing of calorie consumption, dietary composition, or caloric intake offers a promising therapeutic approach for the management of this condition. The aim of this review was to provide a concise analysis of the impact of intermittent fasting on the regulation of glucocorticoid levels and diet-induced metabolic disorders with a focus on non-alcoholic fatty liver diseases. We found that intermittent fasting primarily regulates hepatic autophagy via nutritional and hormonal pathways, aiding in the maintenance of energy equilibrium, enhancement of mitochondrial function, regulation of liver quality, preservation of cellular homeostasis, protection of cells from harmful factors, mitigation of liver metabolic disorders, and improvement of liver inflammation. Also, the physiological changes induced by intermittent fasting and their metabolic consequences arise through multiple mechanisms, including alterations in hepatic metabolism, hepatic autophagy, inflammatory responses, liver functional enzymes, hepatic steatosis, fibroblast growth factor signalling, White adipoe tissue browning, adipokines, circadian rhythms, lipid profiles, body composition, the adipose tissue–gut microbiome axis, skeletal muscle, and the autophagy process. Interestingly, we identified the complex interplay among glucocorticoids, intermittent fasting, and non-alcoholic fatty liver diseases highlighting the hepatic macrophage glucocorticoid receptor as a pivotal mediator of fasting-induced reprogramming of the macrophage secretome, including fasting-suppressed cytokines. In conclusion, existing data indicates that intermittent fasting in patients with non-alcoholic fatty liver diseases is a viable, safe, and successful strategy for weight reduction, demonstrating notable trends in the amelioration of dyslipidaemia and non-alcoholic fatty liver diseases.
消费者在当前食品环境下的危险饮食行为导致了饮食相关代谢紊乱的增加。与代谢(功能障碍)相关的脂肪肝疾病来源是全球主要的健康负担,每年以惊人的速度增加。改变热量消耗的时间,饮食组成,或热量摄入为这种情况的管理提供了一个有希望的治疗方法。本综述的目的是简要分析间歇性禁食对糖皮质激素水平调节和饮食引起的代谢紊乱的影响,重点是非酒精性脂肪性肝病。我们发现,间歇性禁食主要通过营养和激素途径调节肝自噬,有助于维持能量平衡,增强线粒体功能,调节肝脏质量,保持细胞稳态,保护细胞免受有害因素的影响,减轻肝脏代谢紊乱,改善肝脏炎症。此外,间歇性禁食引起的生理变化及其代谢后果通过多种机制产生,包括肝脏代谢、肝自噬、炎症反应、肝功能酶、肝脂肪变性、成纤维细胞生长因子信号传导、白色脂肪组织褐变、脂肪因子、昼夜节律、脂质谱、身体组成、脂肪组织-肠道微生物组轴、骨骼肌和自噬过程的改变。有趣的是,我们发现糖皮质激素、间歇性禁食和非酒精性脂肪性肝病之间存在复杂的相互作用,强调肝巨噬细胞糖皮质激素受体是禁食诱导的巨噬细胞分泌组重编程的关键介质,包括禁食抑制的细胞因子。总之,现有数据表明,非酒精性脂肪性肝病患者间歇性禁食是一种可行、安全、成功的减肥策略,在改善血脂异常血症和非酒精性脂肪性肝病方面表现出显著的趋势。

Aims

Papillary thyroid carcinoma (PTC) is the most common thyroid tumor, usually with a good prognosis, though some cases show early invasion, metastasis, and may become iodine-refractory. circRNAs can interact with miRNAs, bind proteins, regulate transcription, and encode polypeptides, but their translation function in thyroid cancer remains unexplored.

Methods

Quantitative real-time PCR (qRT-PCR), agarose gel electrophoresis, circRNA stability assessment, fluorescence in situ hybridization (FISH) were performed to explore the expression profile of circPTPRM in PTC tissues and adjacent non-cancerous thyroid tissues. We performed molecular biological and cell function experiments by constructing knockdown and various overexpression vectors. Effects of circPTPRM on PTC tumorigenesis were investigated through in vitro and in vivo experiments. The mechanism of circPTPRM-mediated tumor promotion was explored through immunofluorescence (IF), LC-MS/MS, immunoprecipitation (IP) and Co-immunoprecipitation (Co-IP), protein stability assessment, and ubiquitination assay.

Results

We confirmed that circPTPRM influenced PTC cell proliferation, migration, invasion through its translated polypeptides. In vivo experiments with nude mouse tumors also demonstrated that overexpression of circPTPRM contributed to the tumor's increased volume and weight. Subsequently, in the mechanistic analysis we found that circPTPRM-187aa polypeptide could bind IQGAP1 and induce TGF-β pathway activation by elevating RAC1 and CDC42.

Conclusion

CircPTPRM can encode circPTPRM-187aa polypeptide. circPTPRM-187aa, regulates the expression of IQGAP1 protein, and up-regulates RAC1 and CDC42 proteins in TGF-β signaling pathway, enhancing the PTC cells proliferation, migration, and invasion.
目的:甲状腺乳头状癌(PTC)是最常见的甲状腺肿瘤,通常预后良好,但部分病例早期侵袭、转移,并可能成为碘难治性肿瘤。circRNAs可以与mirna相互作用,结合蛋白质,调节转录,编码多肽,但其在甲状腺癌中的翻译功能仍未被探索。方法:采用实时荧光定量PCR (Quantitative real-time PCR, qRT-PCR)、琼脂糖凝胶电泳、circRNA稳定性评估、荧光原位杂交(fluorescence in situ hybridization, FISH)等方法,探讨circPTPRM在PTC组织及癌旁非甲状腺组织中的表达谱。通过构建敲低和各种过表达载体,进行了分子生物学和细胞功能实验。通过体外和体内实验研究circPTPRM对PTC肿瘤发生的影响。通过免疫荧光(IF)、LC-MS/MS、免疫沉淀(IP)和共免疫沉淀(Co-IP)、蛋白稳定性评估和泛素化实验探讨circptprm介导的促瘤机制。结果:我们证实circPTPRM通过其翻译的多肽影响PTC细胞的增殖、迁移和侵袭。裸鼠肿瘤的体内实验也表明,circPTPRM的过表达导致肿瘤体积和重量的增加。随后,在机制分析中,我们发现circPTPRM-187aa多肽可以结合IQGAP1,通过升高RAC1和CDC42诱导TGF-β通路激活。结论:CircPTPRM可编码CircPTPRM -187aa多肽。circPTPRM-187aa,调控IQGAP1蛋白的表达,上调TGF-β信号通路中的RAC1和CDC42蛋白,增强PTC细胞的增殖、迁移和侵袭。

Background

Aggressive Lactotroph Pituitary Neuroendocrine Tumors (Lactotroph PitNETs) usually exhibit invasive growth behavior and resistance to dopamine agonists, showing difficulty in radical treatment and a high recurrence rate. Heat shock protein 90α(Hsp90α),a pivotal isoform of the heat shock protein 90(Hsp90) family, acts as a central chaperone that stabilizes numerous oncoproteins driving tumor progression, but its role in Lactotroph PitNETs remains unclear.

Objective

To study the effect of Hsp90α knockdown on the proliferation and invasiveness of Lactotroph PitNETs cells (MMQ).

Methods

Hsp90α and EGFR expression was compared between 18 aggressive and 22 Non-Aggressive human Lactotroph PitNETs by IHC and immunofluorescence. MMQ rat lactosomatotroph cells were transduced with lentiviral shRNA targeting Hsp90α(shHsp90α). Cell proliferation (CCK8),apoptosis (Annexin-V/7-AAD flow cytometry), Prolactin (PRL) secretion (ELISA), migration and invasion (Transwell) were assessed. Western blotting evaluated EGFR,PRL,AKT,ERK1/2,mTOR,p-AKT,p-ERK1/2 and p-mTOR.

Results

Aggressive Lactotroph PitNETs displayed higher Hsp90α and EGFR expression and showed a notable degree of spatial overlap. Hsp90α knockdown reduced EGFR,AKT,ERK1/2,mTOR,p-AKT,p-ERK1/2 and p-mTOR levels, decreased proliferation, increased apoptosis, lowered PRL secretion, and impaired migration and invasion.

Conclusions

Hsp90α knockdown simultaneously destabilizes EGFR and its downstream AKT/mTOR and ERK axes, resulting in multi-modal suppression of Lactotroph PitNETs invasion. Targeting Hsp90α may offer a novel therapeutic strategy for Aggressive Lactotroph PitNETs refractory to standard medical therapy.
侵袭性垂体神经内分泌乳营养瘤(Lactotroph PitNETs)通常表现出侵袭性生长行为和对多巴胺激动剂的耐药性,难以根治,复发率高。热休克蛋白90α(Hsp90α)是热休克蛋白90(Hsp90)家族的关键亚型,作为一种中心伴侣蛋白,稳定许多驱动肿瘤进展的癌蛋白,但其在乳营养蛋白PitNETs中的作用尚不清楚。目的研究Hsp90α基因下调对嗜乳PitNETs细胞(Lactotroph PitNETs, MMQ)增殖和侵袭性的影响。方法采用免疫组化法和免疫荧光法比较18例侵袭性和22例非侵袭性嗜乳杆菌PitNETs中shsp90 α和EGFR的表达。用靶向Hsp90α(shHsp90α)的慢病毒shRNA转导MMQ大鼠乳生长营养细胞。检测细胞增殖(CCK8)、凋亡(Annexin-V/7-AAD流式细胞术)、泌乳素(PRL)分泌(ELISA)、迁移和侵袭(Transwell)。Western blotting检测EGFR、PRL、AKT、ERK1/2、mTOR、p-AKT、p-ERK1/2和p-mTOR。结果侵袭性嗜乳菌PitNETs具有较高的Hsp90α和EGFR表达,且存在明显的空间重叠。Hsp90α的下调使EGFR、AKT、ERK1/2、mTOR、p-AKT、p-ERK1/2和p-mTOR水平降低,增殖减少,凋亡增加,PRL分泌减少,迁移和侵袭受损。结论shsp90α敲低同时破坏EGFR及其下游AKT/mTOR和ERK轴的稳定性,导致乳营养蛋白PitNETs侵袭的多模式抑制。靶向Hsp90α可能为标准药物治疗难治性侵袭性乳营养不良PitNETs提供新的治疗策略。

Pesticide mixture exposure during critical developmental windows is a growing public health concern, given their potential additive or synergistic effects on the male reproductive system. This study aimed to evaluate whether developmental exposure to a mixture of propiconazole (PRO) and glyphosate (GLY) alters the postpubertal rat prostate. Pregnant rats were orally exposed to vehicle (saline) or a mixture of PRO and GLY (4 mg PRO/kg/day and 3.7 mg GLY/kg/day) from gestation day 9 until weaning. On postnatal day 60, male offspring were euthanized, and the prostate and serum samples were collected. PROGLY-exposed rats exhibited changes in the ventral and dorsolateral prostate histoarchitecture, including epithelial and stromal remodeling and increased incidence of prostate lesions. In the ventral prostate, although the relative glandular area remained unchanged, PROGLY exposure exhibited increased epithelial height and decreased luminal acinar area. Also, hyperplastic and atrophic acini were more prevalent in these animals. PROGLY exposure reduced estrogen receptor beta (ESR2) protein level, particularly in hyperplastic and atrophic acini, without affecting androgen or estrogen receptor alpha. ESR2 decrease was associated with an increased cell proliferation index in hyperplastic acini and a reduction in serum testosterone level in PROGLY-exposed rats. Stromal alterations included increased smooth muscle cell layers and reduced vimentin-positive fibroblasts, with no evidence of myofibroblast presence. This study shows that developmental exposure to PROGLY disrupts normal ventral prostate architecture and hormone signaling in postpubertal rats. These findings highlight the potential long-term risks of combined pesticide exposure on male reproductive health and the importance of evaluating mixture effects.
鉴于农药混合物对男性生殖系统的潜在加性或协同效应,在关键发育窗口期暴露是一个日益严重的公共卫生问题。本研究旨在评估发育暴露于丙环康唑(PRO)和草甘膦(GLY)混合物是否会改变青春期后大鼠的前列腺。妊娠大鼠从妊娠第9天起至断奶,口服载药(生理盐水)或PRO和GLY的混合物(4 mg PRO/kg/day和3.7 mg GLY/kg/day)。在出生后第60天对雄性子代实施安乐死,并收集前列腺和血清样本。progly暴露的大鼠表现出前列腺腹侧和背侧组织结构的变化,包括上皮和间质重塑,前列腺病变发生率增加。在前列腺腹侧,虽然相对腺体面积保持不变,但PROGLY暴露显示上皮高度增加,管腔腺泡面积减少。此外,增生性和萎缩性腺泡在这些动物中更为普遍。PROGLY暴露降低了雌激素受体β (ESR2)蛋白水平,特别是在增生性和萎缩性腺泡中,而不影响雄激素或雌激素受体α。在progly暴露的大鼠中,ESR2的降低与增生性腺泡细胞增殖指数的增加和血清睾酮水平的降低有关。基质改变包括平滑肌细胞层数增加,静脉球蛋白阳性成纤维细胞减少,无肌成纤维细胞存在的证据。本研究表明,发育暴露于PROGLY破坏了青春期后大鼠正常的腹侧前列腺结构和激素信号。这些发现强调了混合农药暴露对男性生殖健康的潜在长期风险以及评估混合效应的重要性。

The field of endocrine oncology is benefiting from broad advances based on key insights in the pathogenesis of neoplasia. While traditionally regarded as unique and distinct entities from non-endocrine neoplasias, deeper molecular profiling studies of endocrine tumors are now challenging this dogma. In this group of papers, experts from across the field provide their perspectives. Each group focuses on a different endocrine gland which they use as a model that highlights the spectrum of disease behavior. It is hoped that collective reflection on these vignettes will reveal new opportunities that can facilitate more effective detection and therapeutic approaches.

Endocrine disorders necessitate diagnostic platforms capable of detecting rapid, low-abundance, fluctuating hormonal signals with high precision. Quantum dot (QD) technology has revolutionized this field by enabling multiplexed, ultrasensitive, and real-time biochemical profiling. Unlike traditional immunoassays limited to single-analyte detection and signal decay, QDs offer exceptional photostability, quantum-level sensitivity, and tunable emission, allowing simultaneous monitoring of various hormonal biomarkers related to thyroid, pancreatic, adrenal, and reproductive dysfunctions. Recent advancements have combined QDs with AI-assisted signal decoding, microfluidics, and wearable biosensor interfaces, creating intelligent systems capable of predicting trends rather than providing static measurements. Functionalized QDs engineered with aptameric, peptidic, or antibody-based recognition domains have shown promising diagnostic capabilities for insulin, estradiol, and thyroid hormones in complex biological samples. As biocompatible QD formulations continue to evolve, their integration with digital health platforms positions them as the next frontier in continuous endocrine monitoring, early disease detection, and personalized hormonal medicine. This review highlights key technological advancements, translational hurdles, and future directions necessary to propel QD-enabled endocrine diagnostics from the laboratory to clinical practice.
内分泌疾病需要能够高精度检测快速、低丰度、波动的激素信号的诊断平台。量子点(QD)技术通过实现多路复用、超灵敏和实时生化分析,彻底改变了这一领域。与传统的仅限于单分析物检测和信号衰减的免疫测定不同,量子点具有优异的光稳定性、量子级灵敏度和可调发射,允许同时监测与甲状腺、胰腺、肾上腺和生殖功能障碍相关的各种激素生物标志物。最近的进展将量子点与人工智能辅助信号解码、微流体和可穿戴生物传感器接口相结合,创造了能够预测趋势的智能系统,而不是提供静态测量。具有适配体、肽或基于抗体的识别结构域的功能化量子点在复杂生物样品中显示出对胰岛素、雌二醇和甲状腺激素的诊断能力。随着生物相容性QD制剂的不断发展,它们与数字健康平台的整合使它们成为持续内分泌监测、早期疾病检测和个性化激素药物的下一个前沿领域。这篇综述强调了推动量子点内分泌诊断从实验室到临床实践所必需的关键技术进步、转化障碍和未来方向。
