7-Ketocholesterol (7-KC) is a biologically active oxysterol formed through the oxidation of cholesterol, predominantly under conditions of oxidative stress. It is generated both enzymatically in specific tissues such as the brain and liver, and non-enzymatically via reactive oxygen species (ROS), especially in aging tissues and heat-processed animal-derived foods. 7-KC exerts multifaceted effects on human health, extending beyond lipid metabolism to disrupt glucose and amino acid utilization, impair mitochondrial function, and provoke endoplasmic reticulum (ER) stress. These disturbances contribute to chronic inflammation and oxidative damage, playing pivotal roles in the development of various diseases, including atherosclerosis, neurodegenerative disorders, diabetes, cancer, hepatic steatosis, and ocular and gastrointestinal pathologies. Additionally, 7-KC is a marker of cholesterol oxidation in the food industry, where it signals product degradation and potential toxicity in long-stored or thermally processed animal-based foods. This review explores the biosynthesis, metabolic fate, and pathophysiological role of 7-KC, highlighting its critical role in intermediary metabolism, disease progression, and food safety. Furthermore, it outlines mitigation strategies to reduce 7-KC exposure through dietary modifications, antioxidant interventions, and advanced food processing technologies aimed at enhancing public health.
7-酮胆固醇(7-KC)是一种具有生物活性的氧甾醇,主要是在氧化应激条件下通过胆固醇氧化形成的。它可以在特定组织(如大脑和肝脏)中酶促产生,也可以通过活性氧(ROS)非酶促产生,特别是在老化组织和热加工的动物源性食品中。7-KC对人体健康具有多方面的影响,不仅限于脂质代谢,还可破坏葡萄糖和氨基酸的利用,损害线粒体功能,并引起内质网(ER)应激。这些紊乱导致慢性炎症和氧化损伤,在各种疾病的发展中起关键作用,包括动脉粥样硬化、神经退行性疾病、糖尿病、癌症、肝脂肪变性、眼部和胃肠道病变。此外,在食品工业中,7-KC是胆固醇氧化的标志,在长期储存或热加工的动物性食品中,它标志着产品降解和潜在毒性。本文综述了7-KC的生物合成、代谢命运和病理生理作用,重点介绍了7-KC在中间代谢、疾病进展和食品安全中的重要作用。此外,它还概述了通过饮食调整、抗氧化干预和旨在加强公众健康的先进食品加工技术来减少7-KC暴露的缓解战略。

Zingerone has various biological properties with a modulatory role in ovarian activity. Despite its biological property, its effect has not been investigated on the uterus. Therefore, the present study has investigated the effects of zingerone supplementation on uterus of mice. Female Swiss albino mice were randomly divided into four groups: control, Z10, Z25, and Z50, where zingerone was orally given for 28 days. Zingerone treatment at 25 and 50 mg/kg increased the number of uterine glands. Immunolocalization of PCNA was decreased in the in vivo study, while in vitro BrdU incorporation was stimulated by the zingerone. Zingerone treatment increased apoptosis at a 25 mg/kg dose; however, zingerone at a 50 mg/kg dose decreased uterine apoptosis. In vitro study also showed zingerone down-regulates BCL2 expression and up-regulates active caspase expression. These findings suggest modulatory effects of zingerone on uterine proliferation and apoptosis. The pro-inflammatory TNFα showed the lowest expression in 50 mg/kg zingerone-treated mice uterus. In vitro findings also showed that zingerone decreased expression of TNFα. Furthermore, an in vivo study has also shown zingerone down-regulates INSR and GLUT4 without affecting uterine glucose concentration. In addition, an in vitro study has also shown that zingerone down-regulates INSR. Zingerone treatment showed elevated MDA levels and GPX enzyme activity. However, SOD activity was suppressed in 25 and 50 mg/kg groups. Furthermore, catalase activity was highest in the 50 mg/kg zingerone-treated group. Thus, these results showed the modulatory role of zingerone on apoptosis, glucose metabolism, and antioxidant status in uterus. The functional significance of zingerone-mediated parameters on uterine functions remains to be investigated.
生姜酮具有多种生物学特性,对卵巢活性具有调节作用。尽管其具有生物学特性,但其对子宫的影响尚未被研究。因此,本研究探讨了补充生姜酮对小鼠子宫的影响。雌性瑞士白化病小鼠随机分为对照组、Z10组、Z25组和Z50组,每组口服青姜酮28 d。生姜酮25、50mg/kg组大鼠子宫腺数量增加。在体内研究中,PCNA的免疫定位降低,而在体外,生姜酮刺激BrdU掺入。25mg/kg剂量的姜酮增加了细胞凋亡;50mg/kg剂量的姜酮可抑制子宫细胞凋亡。体外研究也显示姜酮下调BCL2表达,上调活性caspase表达。提示姜酮对子宫增殖和细胞凋亡具有调节作用。促炎TNFα在50mg/kg黄酮处理小鼠子宫中表达最低。体外实验结果也显示姜酮能降低TNFα的表达。此外,一项体内研究也表明生姜酮下调INSR和GLUT4而不影响子宫葡萄糖浓度。此外,一项体外研究也表明,生姜酮下调INSR。生姜酮处理后,MDA水平和GPX酶活性均升高。25和50mg/kg组SOD活性受到抑制。过氧化氢酶活性以50mg/kg姜酮处理组最高。由此可见,姜酮对子宫细胞凋亡、糖代谢和抗氧化的调节作用。黄酮介导的参数对子宫功能的功能意义有待进一步研究。

7-Ketocholesterol (7-KC), a major oxysterol formed through cholesterol autoxidation, is increasingly recognized as a pathogenic mediator in ageing and chronic disease. Detected in atherosclerotic plaques, Alzheimer’s cortex, aged retina, and lysosomal storage disorders, 7-KC actively drives oxidative stress, chronic inflammation, organelle dysfunction, and oxiapoptophagy. These mechanisms underpin its role in cardiovascular, neurodegenerative, and metabolic pathologies. Recent advances highlight nutritional antioxidants, pharmacological agents, microbial bioremediation, and nanotechnology as promising therapeutic avenues. Recognizing 7-KC as both a biomarker and therapeutic target offers opportunities for innovation in diagnostics and treatment of age-related and inflammatory disorders.
7-酮胆固醇(7-KC)是通过胆固醇自氧化形成的一种主要的氧甾醇,越来越被认为是衰老和慢性疾病的致病介质。在动脉粥样硬化斑块、阿尔茨海默氏症皮层、老化视网膜和溶酶体贮积障碍中检测到的7-KC积极驱动氧化应激、慢性炎症、细胞器功能障碍和氧化细胞吞噬。这些机制支持其在心血管、神经退行性和代谢病理中的作用。最近的进展强调营养抗氧化剂、药物、微生物生物修复和纳米技术是有前途的治疗途径。认识到7-KC既是一种生物标志物,也是一种治疗靶点,为年龄相关疾病和炎症性疾病的诊断和治疗提供了创新机会。

The host organism's balance within the body relies on its crucial symbiotic relationship with gut microbiota. This balance, known as homeostasis, can be influenced by various factors. One significant factor is the role of bacterial metabolites from different substrates, such as tryptophan. Recent research has revealed that these metabolites impact many biological processes. Microbial metabolites, such as Indole-3-Propionic Acid (IPA), are produced by the intestinal microbiota by converting dietary tryptophan. IPA is absorbed by intestinal epithelial cells, transported via the portal circulation, undergoes minimal hepatic metabolism, and is subsequently released into the systemic circulation to reach peripheral tissues and exert its biological effects. The Pregnane X receptor (PXR) and aryl hydrocarbon receptor (AhR) are the two main receptors of IPA which induce different gene expression profiles and subsequently diverse biological pathways in different tissues. Once absorbed by intestinal epithelial cells, IPA is released into the circulatory system and can significantly affect the immune, cardiovascular, nervous, and gastrointestinal systems. Furthermore, IPA has been found to have positive effects on a cellular level by inhibiting oxidative stress injury and preventing the synthesis of proinflammatory cytokines. Numerous studies have highlighted IPA's antioxidant, anti-inflammatory, anti-cancer, and neuroprotective effects. Therefore, dysbiosis of IPA contributes to disorders such as metabolic syndromes, inflammatory conditions, cancer, and neuropsychiatric diseases. This review provides a detailed examination of the most recent studies on indole-3-propionic acid function through PXR and AhR, outlining its molecular signaling pathways and correlation with various diseases.
宿主生物在体内的平衡依赖于它与肠道微生物群的重要共生关系。这种平衡被称为体内平衡,可以受到各种因素的影响。一个重要的因素是来自不同底物的细菌代谢物的作用,如色氨酸。最近的研究表明,这些代谢物影响许多生物过程。微生物代谢物,如吲哚-3-丙酸(IPA),是由肠道菌群通过转化膳食色氨酸产生的。IPA被肠上皮细胞吸收,经门静脉循环运输,经过最低限度的肝脏代谢,随后释放进入体循环到达外周组织,发挥其生物学作用。孕烷X受体(PXR)和芳烃受体(AhR)是IPA的两个主要受体,它们在不同的组织中诱导不同的基因表达谱和不同的生物学途径。IPA一旦被肠上皮细胞吸收,释放到循环系统,可显著影响免疫、心血管、神经和胃肠道系统。此外,IPA已被发现在细胞水平上具有抑制氧化应激损伤和防止促炎细胞因子合成的积极作用。许多研究都强调了IPA的抗氧化、抗炎、抗癌和神经保护作用。因此,IPA的失调会导致代谢综合征、炎症、癌症和神经精神疾病等疾病。本文综述了吲哚-3-丙酸通过PXR和AhR功能的最新研究进展,概述了其分子信号通路及其与多种疾病的关系。

7-Ketocholesterol (7-KC), a cytotoxic oxysterol generated through cholesterol oxidation, plays a central role in the progression of atherosclerosis, neurodegeneration, and metabolic syndromes through mitochondrial dysfunction, ROS overproduction, and NLRP3 inflammasome activation. This study presents the first integrative systems pharmacology analysis exploring the molecular mechanisms by which β-sitosterol (BS), a phytosterol with antioxidant and anti-inflammatory properties, mitigates 7KC-induced toxicity. Shared targets between BS and 7KC were identified through target prediction databases and subjected to protein–protein interaction (PPI) network analysis using Cytoscape with bottleneck centrality. Top hub genes were functionally enriched using Gene Ontology and KEGG pathway tools, revealing BS’s modulation of nuclear receptor activity, redox homeostasis, and OXPHOS pathways. BS targets were localized across cytosol, nucleus, and membrane compartments, supporting its multi-compartmental regulatory role. This mechanistic framework highlights BS as a potential nutraceutical intervention for 7KC-driven chronic diseases, including atherosclerosis, NAFLD, and Alzheimer’s disease, warranting further biological validation.

Background

Vitamin D is a known immunomodulator, but its predictive value in COVID-19 remains incompletely understood. This study investigates the role of vitamin D across molecular, biochemical, and histopathological levels to evaluate its association with COVID-19 severity and mortality.

Methods

A prospective case-control study was conducted in the Kurdistan Region of Iraq from May to October 2021. Ninety-five confirmed COVID-19 patients (75 survivors, 20 non-survivors) and 75 healthy controls were enrolled. Serum 25(OH)D levels were quantified by ELISA. Clinical severity was assessed using CURB-65, NEWS, and SOFA scores. Genotyping for the FokI (rs2228570) polymorphism in the VDR gene was performed via allele-specific PCR. Lung tissue from five survivors (biopsy) and five non-survivors (autopsy) underwent immunohistochemical staining to evaluate VDR expression.

Results

Serum vitamin D concentrations were markedly reduced in non-survivors (20.34 ± 0.46 ng/mL) relative to survivors (40.11 ± 0.28 ng/mL, p < 0.001). Vitamin D exhibited a negative correlation with CURB-65 (r = –0.828), NEWS (r = –0.794), and SOFA (r = –0.762) scores. Regression analysis established that vitamin D was independently associated with disease severity in our population. The TT genotype of the FokI VDR polymorphism correlated with markedly reduced vitamin D levels and elevated severity scores. Mortality exhibited a strong association with the TT genotype (OR = 10.29, 95 % CI: 2.204–49.19, p = 0.003) and the T allele (OR = 3.923, p = 0.0006). ROC analysis determined a vitamin D threshold of ≤ 20.56 ng/mL as indicative of mortality (AUC = 0.784, p < 0.0001). Immunohistochemistry demonstrated elevated VDR expression in lung tissues of deceased COVID-19 patients relative to VDR-negative controls.

Conclusion

This study indicates that serum vitamin D levels, VDR gene polymorphism (rs2228570), and lung tissue VDR expression are strongly correlated with the severity and mortality of COVID-19. These findings validate the clinical use of vitamin D and VDR profiling may have associative markers and prospective treatment targets in the management of COVID-19.
维生素D是一种已知的免疫调节剂,但其对COVID-19的预测价值仍不完全清楚。本研究探讨了维生素D在分子、生化和组织病理学水平上的作用,以评估其与COVID-19严重程度和死亡率的关系。方法于2021年5 - 10月在伊拉克库尔德斯坦地区进行前瞻性病例对照研究。纳入了95名确诊的COVID-19患者(75名幸存者,20名非幸存者)和75名健康对照。ELISA法测定血清25(OH)D水平。使用CURB-65、NEWS和SOFA评分评估临床严重程度。通过等位基因特异性PCR对FokI (rs2228570) VDR基因多态性进行基因分型。对5名幸存者(活检)和5名非幸存者(尸检)的肺组织进行免疫组织化学染色以评估VDR表达。结果非幸存者血清维生素D浓度(20.34±0.46 ng/mL)明显低于幸存者(40.11±0.28 ng/mL, p < 0.001)。维生素D与CURB-65 (r = -0.828)、NEWS (r = -0.794)、SOFA (r = -0.762)得分呈负相关。回归分析表明,在我们的人群中,维生素D与疾病严重程度独立相关。FokI VDR多态性的TT基因型与维生素D水平显著降低和严重程度评分升高相关。死亡率与TT基因型(OR = 10.29, 95 % CI: 2.204 ~ 49.19, p = 0.003)和T等位基因(OR = 3.923, p = 0.0006)密切相关。ROC分析确定维生素D阈值≤ 20.56 ng/mL作为死亡率的指示值(AUC = 0.784, p <; 0.0001)。免疫组织化学显示,与VDR阴性对照相比,死亡COVID-19患者肺组织中VDR表达升高。结论血清维生素D水平、VDR基因多态性(rs2228570)和肺组织VDR表达与COVID-19的严重程度和死亡率密切相关。这些发现验证了维生素D的临床应用和VDR谱分析可能在COVID-19的管理中具有相关标记和前瞻性治疗靶点。

Research on the effects of the mineralocorticoid receptor (MR) suggested a role in innate and adaptive immune responses. The inflammatory profile is directly linked to MR activation in several pathologies such as cardiovascular diseases, autoimmunity, chronic renal disease and obesity. MR is a high-affinity receptor binding both mineralocorticoids and glucocorticoids. In this study, we explored the pharmacological modulation of MR with the mineralocorticoid agonist deoxycorticosterone (DOCA) and the antagonist spironolactone (SPIRO) on corticosterone levels in plasma, neuroinflammation, myelin status and neurodegeneration in the spinal cord of mice with experimental autoimmune encephalomyelitis (EAE) model of Multiple Sclerosis. Animals were treated from day 1 until sacrificed on day 17 post-induction, and experimental groups were divided into: EAE+DOCA (0.75 mg/kg s.c every 3 days), EAE+DOCA+SPIRO (Spironolactone: 25 mg/kg i.p daily), vehicle-treated EAE (EAE+VEH) and Control (CTRL). Administration of DOCA or vehicle to EAE conducted to similar neuropathological alterations. The MR antagonist (a) significantly decreased inflammatory parameters TLR4, IL-1β and microglial CD11b mRNAs and showed a tendency to reduced osteopontin, b) reduced the % of infiltrated cellular and demyelinated area, as well as the reactive gliosis (GFAP+ area and number of IBA1 + cells) vs EAE+DOCA (c) increased the area of the neuronal marker NeuN vs EAE+DOCA and EAE+VEH groups (d) improved functional performance in the rotarod test and clinical signs vs EAE+DOCA. Interestingly, plasma corticosterone was increased in EAE+VEH and EAE+DOCA vs CTRL, while SPIRO administration raised even more corticosterone levels. This hypercorticosteronemia had functional consequences, because the glucocorticoid receptor (GR) and the target gene serum glucocorticoid regulated kinase 1 (SGK1) mRNAs expression were also increased vs DOCA alone. We hypothesized that MR blockage with SPIRO downregulated inflammation-related spinal cord pathology whereas excess glucocorticoids circulating in the EAE+DOCA+SPIRO group may contribute to anti-inflammatory effects.
对矿化皮质激素受体(MR)作用的研究表明其在先天和适应性免疫反应中起作用。在心血管疾病、自身免疫、慢性肾脏疾病和肥胖等多种疾病中,炎症谱与MR激活直接相关。MR是一种结合矿皮质激素和糖皮质激素的高亲和力受体。在这项研究中,我们探讨了矿化皮质激素激动剂脱氧皮质酮(DOCA)和拮抗剂螺内酯(SPIRO)对多发性硬化症实验性自身免疫性脑脊髓炎(EAE)模型小鼠血浆皮质酮水平、神经炎症、髓磷脂状态和脊髓神经退行性变的药理学调节。诱导后第1天至第17天处死,实验组分为EAE+DOCA(0.75 mg/kg s.c / 3 d)、EAE+DOCA+SPIRO(螺内酯:25 mg/kg i.p / d)、载药EAE (EAE+VEH)和对照组(CTRL)。对EAE给予DOCA或载药可引起类似的神经病理改变。MR拮抗剂(a)显著降低炎症参数TLR4、IL-1β和小胶质细胞CD11b mrna,并有降低骨桥蛋白的倾向;b)与EAE+DOCA相比,降低了细胞渗透和脱髓鞘面积的百分比,以及反应性胶质瘤(GFAP+面积和IBA1 +细胞数量);c)与EAE+DOCA和EAE+VEH组相比,增加了神经元标记物NeuN的面积;d)与EAE+DOCA组相比,改善了rotarod试验的功能表现和临床症状。有趣的是,与对照组相比,EAE+VEH和EAE+DOCA组血浆皮质酮水平升高,而SPIRO组提高的皮质酮水平更高。这种高皮质酮血症具有功能性后果,因为糖皮质激素受体(GR)和靶基因血清糖皮质激素调节激酶1 (SGK1) mrna的表达也比单独使用DOCA增加。我们假设SPIRO的MR阻塞下调了炎症相关的脊髓病理,而EAE+DOCA+SPIRO组中循环的过量糖皮质激素可能有助于抗炎作用。

Breast cancer (BC) is one of the most prevalent malignant tumors among women, with estrogen receptor (ER)-positive patients constituting approximately 70 % of all cases. Endocrine therapy is currently a treatment option for patients with ER-positive BC; however, the development of resistance significantly limits the effectiveness of this treatment. Nano-curcumin (Nano-CUR) possesses anticancer properties and enhances bioavailability by improving the hydrophobic character of curcumin (CUR). However, the underlying mechanism by which Nano-CUR affects tamoxifen (TAM) resistance in ER-positive BC remains unknown. Here, we found that Nano-CUR promoted apoptosis and cell cycle arrest, inhibited cell proliferation and reduced the levels of cancer stem cells (CSCs)-related markers, including octamer-binding protein (OCT4), Nanog homeobox (NANOG) and sex-determining region Y-box 2 (SOX2) in TAM-resistant BC cells. Additionally, Nano-CUR demonstrated the ability to inhibit tumor malignant progression in TAM-treated BC mice. Mechanistically, Nano-CUR blocked the activation of the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT)/mammalian target of rapamycin (mTOR) pathway in MCF-7/TAM and T47D/TAM cells. The activation of this pathway by its activators (PI3K activator 740Y-P, AKT activator SC-79, and mTOR activator MHY1485) effectively alleviated the anti-tumor effect induced by Nano-CUR in TAM-resistant BC cells. Collectively, these findings reveal that Nano-CUR contributes to the reduction of tumorigenesis and TAM resistance in ER-positive BC cells by inhibiting the PI3K/AKT/mTOR signaling pathway.
乳腺癌(BC)是女性中最常见的恶性肿瘤之一,雌激素受体(ER)阳性患者约占所有病例的70%。内分泌治疗是目前er阳性BC患者的一种治疗选择;然而,耐药性的发展极大地限制了这种治疗的有效性。纳米姜黄素(nanocurcumin, Nano-CUR)通过改善姜黄素(curcumin, CUR)的疏水性来提高生物利用度,并具有抗癌特性。然而,Nano-CUR影响er阳性BC中他莫昔芬(TAM)耐药性的潜在机制尚不清楚。在这里,我们发现Nano-CUR促进细胞凋亡和细胞周期阻滞,抑制细胞增殖,降低癌症干细胞(CSCs)相关标志物的水平,包括抗tam BC细胞中的八聚体结合蛋白(OCT4), Nanog同源盒(Nanog)和性别决定区Y-box 2 (SOX2)。此外,Nano-CUR在tam治疗的BC小鼠中显示出抑制肿瘤恶性进展的能力。在机制上,Nano-CUR阻断了MCF-7/TAM和T47D/TAM细胞中磷脂酰肌醇3-激酶(PI3K)/蛋白激酶B (AKT)/哺乳动物雷帕霉素靶蛋白(mTOR)通路的激活。该通路的激活剂(PI3K激活剂740Y-P、AKT激活剂SC-79和mTOR激活剂MHY1485)可有效缓解Nano-CUR对tam耐药BC细胞的抗肿瘤作用。综上所述,这些发现表明Nano-CUR通过抑制PI3K/AKT/mTOR信号通路,有助于减少er阳性BC细胞的肿瘤发生和TAM耐药性。
