Ganoderma lucidum, a popular medicinal fungus, has been utilized to treat a variety of diseases. It possesses a unique therapeutic and pharmacological reputation in suppressing cancer/tumor progression, especially breast cancer, due to its embedded rich bioactive chemical constituents, mainly triterpenoids (ganoderic acids). The most prevalent malignant tumor in women with a high mortality and morbidity rate is breast cancer. Ganoderic acids A, D, DM, F, and H are evidenced in previous research to have breast cancer-preventive properties by exhibiting autophagic and apoptosis, anti-proliferative, and anti-angiogenesis effects. However, the anti-breast cancer mechanism remains unclear. The putative targets of the ganoderic acids were further determined using bioinformatics techniques and molecular docking calculation. Finally, the key targets were verified in vitro. A total of 53 potential target proteins associated with 202 pathways were predicted to be related to breast cancer. The potential targets were narrowed down to six key targets (AKT1, PIK3CA, epidermal growth factor receptor [EGFR], STAT1, ESR1, and CTNNB1), using different algorithms of the CytoHubba plugin, which were further validated using molecular docking analysis. The ganoderic acid DM (GADM) and the targets (PIK3CA and EGFR) with the strongest interactions were validated via MDA-MB-231 and MCF7 cells. The expression level of PIK3CA in both MDA-MB-231 and MCF7 cells was dose-dependently suppressed by GADM, whereas EGFR expression was unexpectedly increased, which warrants further investigation. These data indicated that the network pharmacology-based prediction of GADM targets for treating human breast cancer could be reliable.

灵芝是一种广受欢迎的药用真菌,已被用于治疗多种疾病。灵芝含有丰富的生物活性化学成分,主要是三萜类化合物(灵芝酸),因此在抑制癌症/肿瘤进展,特别是乳腺癌方面具有独特的治疗和药理作用。乳腺癌是女性最常见的恶性肿瘤,死亡率和发病率都很高。以前的研究证明,灵芝酸 A、D、DM、F 和 H 具有自噬和凋亡、抗增殖和抗血管生成的作用,从而具有预防乳腺癌的特性。然而,其抗乳腺癌的机制仍不清楚。利用生物信息学技术和分子对接计算进一步确定了灵芝酸的推定靶点。最后,对关键靶点进行了体外验证。共预测出与乳腺癌相关的 53 个潜在靶蛋白,涉及 202 个通路。利用CytoHubba插件的不同算法,将潜在靶标缩小到六个关键靶标(AKT1、PIK3CA、表皮生长因子受体[EGFR]、STAT1、ESR1和CTNNB1),并进一步通过分子对接分析进行验证。通过 MDA-MB-231 和 MCF7 细胞验证了甘露二酸 DM(GADM)和相互作用最强的靶标(PIK3CA 和表皮生长因子受体)。PIK3CA 在 MDA-MB-231 和 MCF7 细胞中的表达水平受到 GADM 的剂量依赖性抑制,而 EGFR 的表达却意外增加,这值得进一步研究。这些数据表明,基于网络药理学预测 GADM 治疗人类乳腺癌的靶点是可靠的。

Periodontitis is an inflammatory condition that affects the tooth-supporting structures, triggered by the host's immune response toward the bacterial deposits around the teeth. Annexin A1 (AnxA1), a vital member of the annexin superfamily, is known for its diverse physiological functions, particularly its anti-inflammatory and anti-senescence properties. We hypothesized that AnxA1 has a protective effect against lipopolysaccharide (LPS)-induced inflammatory responses and cellular damage in periodontal ligament cells (PDLCs). In this study, we demonstrate that LPS stimulation significantly reduced telomerase activity in PDLCs, a decline that was dose-dependently reversed by AnxA1. Importantly, AnxA1 protected the cells from LPS-induced cellular senescence and the downregulation of human telomerase reverse transcriptase (hTERT) expression. In line with this, AnxA1 suppressed the LPS-induced expression of p21 and p16 at both the mRNA and protein levels. Furthermore, AnxA1 demonstrated potent anti-inflammatory effects by inhibiting the secretion of interleukin 6 (IL-6), interleukin 8 (IL-8), and monocyte chemoattractant protein-1 (MCP-1). It also mitigated LPS-induced oxidative stress by reducing the levels of phosphorylated Foxo3a (Ser253) and restored sirtuin 1 (SIRT1) expression. Notably, SIRT1 silencing abolished AnxA1's protective effects on Foxo3a phosphorylation and cellular senescence, suggesting that SIRT1 mediates AnxA1's actions. In conclusion, AnxA1 protected PDLCs against LPS-triggered inflammation and cell senescence by activating SIRT1 signal pathway. These findings indicate that AnxA1 could serve as a promising therapeutic strategy for the treatment of periodontitis.

牙周炎是一种影响牙齿支撑结构的炎症,由宿主对牙齿周围细菌沉积物的免疫反应引发。附件蛋白 A1(Annexin A1)是附件蛋白超家族的一个重要成员,它具有多种生理功能,尤其是抗炎和抗衰老特性。我们假设 AnxA1 对脂多糖(LPS)诱导的牙周韧带细胞(PDLCs)炎症反应和细胞损伤具有保护作用。在这项研究中,我们证明了 LPS 的刺激会显著降低牙周韧带细胞的端粒酶活性,而 AnxA1 则可以剂量依赖性地逆转这种下降。重要的是,AnxA1能保护细胞免受LPS诱导的细胞衰老和人类端粒酶逆转录酶(hTERT)表达的下调。与此相应,AnxA1 在 mRNA 和蛋白质水平上抑制了 LPS 诱导的 p21 和 p16 的表达。此外,AnxA1 还能抑制白细胞介素 6(IL-6)、白细胞介素 8(IL-8)和单核细胞趋化蛋白-1(MCP-1)的分泌,从而显示出强大的抗炎作用。它还通过降低磷酸化 Foxo3a(Ser253)的水平和恢复 sirtuin 1(SIRT1)的表达,减轻了 LPS 诱导的氧化应激。值得注意的是,沉默 SIRT1 可消除 AnxA1 对 Foxo3a 磷酸化和细胞衰老的保护作用,这表明 SIRT1 介导了 AnxA1 的作用。总之,AnxA1通过激活SIRT1信号通路保护PDLCs免受LPS引发的炎症和细胞衰老的影响。这些研究结果表明,AnxA1可作为治疗牙周炎的一种有前途的治疗策略。

This study aimed to evaluate the potential of ethanolic extract of propolis on the secondary lesions of the liver, renal, and pancreatic that were derived by primary colorectal cancer, and comparison of the ethanolic extract of propolis with the vitamin E. The groups included the control, ethanolic extract of propolis, vitamin E, dimethylhydrazine, dimethylhydrazine + ethanolic extract of propolis, and dimethylhydrazine + vitamin E. After 13 weeks of treatment, the blood and tissue samples were taken from all the rats, and alanine transaminase, aspartate transaminase, alkaline phosphatase, uric acid, creatinine, blood urea nitrogen, insulin, amylase, and lipase indices along with the tissue pathological examination of the kidney, liver, and pancreas were evaluated. Ethanolic extract of propolis effectively alleviated the colorectal cancer-induced secondary lesions in the liver by significantly lowering the alanine transaminase significantly. Ethanolic extract of propolis significantly decreased uric acid in rats; and also significantly elevated the pancreatic insulin. In addition, inflammation and cell necrosis indices in all these tissues were significantly reduced when ethanolic extract of propolis was consumed compared to the dimethylhydrazine group. It seemed ethanolic extract of propolis showed high antioxidant, anticancer, and anti-inflammatory potentials, and can be used practically to reduce the side lesions of colorectal cancer.

本研究旨在评估蜂胶乙醇提取物对原发性大肠癌引起的肝脏、肾脏和胰腺继发性病变的潜在影响,并比较蜂胶乙醇提取物与维生素E的作用。治疗 13 周后,对所有大鼠进行血液和组织采样,评估丙氨酸转氨酶、天门冬氨酸转氨酶、碱性磷酸酶、尿酸、肌酐、血尿素氮、胰岛素、淀粉酶和脂肪酶指数,以及肾脏、肝脏和胰腺的组织病理学检查。蜂胶乙醇提取物能显著降低丙氨酸转氨酶,从而有效缓解结直肠癌引起的肝脏继发性病变。蜂胶乙醇提取物能明显降低大鼠的尿酸,还能明显提高胰岛素。此外,与二甲基肼组相比,服用蜂胶乙醇提取物后,所有这些组织的炎症和细胞坏死指数都明显降低。由此看来,蜂胶乙醇提取物具有很高的抗氧化、抗癌和抗炎潜力,可用于减少结直肠癌的副作用。

Dilated cardiomyopathy (DCM) is the most common type of myocardial dysfunction, affecting mostly young adults, but its therapeutic diagnosis and biomarkers for prognosis are lacking. This study aimed to investigate the possible effect of the common food additive monosodium glutamate (MSG) and tannic acid (TA), a phenolic compound, on the key molecular actors responsible for DCM. DCM-related publicly available microarray datasets (GSE120895, GSE17800, and GSE19303) were downloaded from the comprehensive Gene Expression Omnibus (GEO) database, and analyzed to identify differentially expressed genes (DEGs). By integrating DEGs and gene-disease validity curation results, overlapping genes were screened and identified as hub genes. Protein-protein interaction (PPI) network and ontology analysis were performed to make sense of the identified biological data. Finally, mRNA expression changes of identified hub genes in the heart tissues of rats treated with MSG and TA were measured by the qPCR method. Six upregulated (IGF1, TTN, ACTB, LMNA, EDN1, and NPPB) DEGs were identified between the DCM and healthy control samples as the hub genes. qPCR results revealed that the mRNA levels of these genes involved in DCM development increased significantly in rat heart tissues exposed to MSG. In contrast, this increase was remarkably alleviated by TA treatment. Our results provide new insights into critical molecular mechanisms that should be focused on in future DCM studies. Moreover, MSG may play a critical role in DCM formation, and TA may be used as a promising therapeutic agent in DCM.

扩张型心肌病(DCM)是最常见的心肌功能障碍类型,多发于青壮年,但目前尚缺乏治疗诊断和预后生物标志物。本研究旨在探讨常见食品添加剂味精(MSG)和酚类化合物单宁酸(TA)对导致 DCM 的关键分子角色可能产生的影响。研究人员从综合性基因表达总库(GEO)数据库中下载了与DCM相关的公开微阵列数据集(GSE120895、GSE17800和GSE19303),并对其进行了分析,以确定差异表达基因(DEGs)。通过整合 DEGs 和基因-疾病有效性策展结果,筛选出重叠基因并确定为枢纽基因。通过蛋白质-蛋白质相互作用(PPI)网络和本体分析,对所识别的生物数据进行了意义分析。最后,采用 qPCR 方法测定了经 MSG 和 TA 处理的大鼠心脏组织中已确定的中心基因的 mRNA 表达变化。qPCR 结果显示,在暴露于味精的大鼠心脏组织中,这些参与 DCM 发生的基因的 mRNA 水平显著升高。与此相反,TA 治疗显著缓解了这种增加。我们的研究结果为未来 DCM 研究应关注的关键分子机制提供了新的见解。此外,味精可能在 DCM 的形成过程中起着关键作用,而 TA 则可能被用作一种治疗 DCM 的药物。

Cervical cancer (CC) poses a threat to human health. Enhancing pyroptosis can prevent the proliferation and epithelial–mesenchymal transition (EMT) of tumor cells. This study aims to reveal the candidates that modulate pyroptosis in CC. Accordingly, the common microRNAs (miRNAs/miRs) that were sponged by RBPMS antisense RNA 1 (RBPMS-AS1) and could target Phospholipase C–Like 1 (PLCL1) were intersected. The expression of PBPMS-AS1/miR-19a-3p (candidate miRNA)/PLCL1 was predicted in cervical squamous cell carcinoma (CESC), by which the expression location of RBPMS-AS1 and the binding between RBPMS-AS1/PLCL1 and miR-19a-3p were analyzed. The targeting relationship between RBPMS-AS1/PLCL1 and miR-19a-3p was confirmed by dual-luciferase reporter assay. After the transfection, cell counting kit-8 assay, colony formation assay, quantitative reverse transcription PCR, and Western blot were implemented for cell viability and proliferation analysis as well as gene and protein expression quantification analysis. Based on the results, RBPMS-AS1 and PLCL1 were lowly expressed, yet miR-19a-3p was highly expressed in CESC. RBPMS-AS1 overexpression diminished the proliferation and expressions of N-cadherin, vimentin, and miR-19a-3p, yet enhanced those of E-cadherin, PLCL1, and pyroptosis-relevant proteins (inteleukin-1β, caspase-1, and gasdermin D N-terminal). However, the above RBPMS-AS1 overexpression–induced effects were counteracted in the presence of miR-19a-3p. There also existed a targeting relationship and negative interplay between PLCL1 and miR-19a-3p. In short, RBPMS-AS1 sponges miR-19a-3p and represses the growth and EMT of CC cells via enhancing PLCL1-mediated pyroptosis.
宫颈癌(CC)对人类健康构成威胁。加强热蛋白沉积可以防止肿瘤细胞的增殖和上皮-间质转化(EMT)。本研究旨在揭示调控CC中热变性的候选基因。因此,研究人员交叉研究了RBPMS反义RNA 1(RBPMS-AS1)海绵化的常见微RNA(miRNA/miRs),这些微RNA可靶向磷脂酶C-Like 1(PLCL1)。通过预测 PBPMS-AS1/miR-19a-3p (候选 miRNA)/PLCL1 在宫颈鳞状细胞癌(CESC)中的表达,分析了 RBPMS-AS1 的表达位置以及 RBPMS-AS1/PLCL1 与 miR-19a-3p 之间的结合。RBPMS-AS1/PLCL1与miR-19a-3p之间的靶向关系通过双荧光素酶报告实验得到了证实。转染后,通过细胞计数试剂盒-8 检测、菌落形成检测、定量反转录 PCR 和 Western 印迹进行细胞活力和增殖分析,以及基因和蛋白表达定量分析。结果显示,RBPMS-AS1和PLCL1在CESC中低表达,而miR-19a-3p在CESC中高表达。RBPMS-AS1的过表达降低了N-钙粘蛋白、波形蛋白和miR-19a-3p的增殖和表达,但增强了E-钙粘蛋白、PLCL1和热休克相关蛋白(白细胞介素-1β、caspase-1和gasdermin D N-terminal)的表达。然而,在 miR-19a-3p 的存在下,上述 RBPMS-AS1 过表达诱导的效应被抵消。PLCL1 和 miR-19a-3p 之间还存在靶向关系和负向相互作用。总之,RBPMS-AS1通过增强PLCL1介导的热蛋白沉积抑制了miR-19a-3p,并抑制了CC细胞的生长和EMT。

Mesoporous silica nanoparticles (MSNs) have displayed high-potential prospects in biomedical use, especially for drug delivery due to large surface area, tunable pore size and simple surface functionalization. The objective behind the present research is to synthesize and profile piperine-modified MSNs for their preparation due to antioxidative anticarcinogenic, anti-inflammatory properties of the alkaloid chosen as a modifier. In the study, silica piperine nanoparticles (SPN) were fabricated based on a modified Stöber method. Characterization techniques including SEM, TEM, AFM, FTIR, XRD, and DSC showed significant differences of incorporated piperine in the production process to plain MSN properties. Piperine was observed to inhibit nanoparticles’ growth so that they became smaller, heterogeneous, with a changed morphology and surface chemistry. As a strong confirmation of covalent incorporation, spectroscopic data showed the presence of electrons in the piperine's functional group that were exchanged into some silanol groups and removed excessive surface energy. The antioxidant activity of SPNs revealed that the silica matrix, and moreover bioactive piperine combination resulted to significant increase in enhanced antioxidant potential.

介孔二氧化硅纳米粒子(MSNs)因其比表面积大、孔径可调、表面功能化简单等特点,在生物医学领域,特别是在药物输送方面显示出了巨大的潜力。本研究的目的是合成哌啶修饰的 MSNs 并对其进行剖析,因为这种生物碱具有抗氧化、抗癌、抗炎等特性。本研究采用改良的斯托伯(Stöber)方法制备了二氧化硅胡椒碱纳米粒子(SPN)。包括扫描电镜、电子显微镜、原子力显微镜、傅立叶变换红外光谱、X 射线衍射和 DSC 在内的表征技术表明,在生产过程中掺入胡椒碱与普通 MSN 特性之间存在显著差异。据观察,胡椒碱抑制了纳米粒子的生长,使其变得更小、异质、形态和表面化学性质发生了变化。作为共价结合的有力证明,光谱数据显示胡椒碱官能团中存在电子,这些电子被交换到一些硅醇基团中,消除了过多的表面能。SPN 的抗氧化活性表明,二氧化硅基质和具有生物活性的胡椒碱的结合显著增强了抗氧化潜力。总之,这项研究的结果为如何利用和处理胡椒碱以适应 MSN 提供了有意义的启示,目的是优化其生物医学用途,如药物输送应用,因为其抗氧化特性可能会带来治疗效果。哌啶修饰 MSN 的整体表征和标准化为进一步的项目实践和推进生物医学应用铝硅酸盐纳米结构的调整奠定了坚实的基础。

Psoriasis is a common immune-related polygenic inflammatory skin disease. Salidroside (SAL) exerts anti-inflammatory and antioxidant effects and is used to treat skin diseases. However, the specific effects of SAL on psoriasis remain unclear. In this study, we aimed to investigate the efficacy of SAL for psoriasis treatment. Mice were treated with imiquimod (IMQ) to establish an in vivo psoriasis model. Histological analysis was conducted via hematoxylin and eosin staining. Cytokine release was determined via enzyme-linked immunosorbent assay. Additionally, mRNA levels were determined via reverse transcription-quantitative polymerase chain reaction. Protein expression was assessed via Western blotting. Gasdermin D (GSDMD) and Ki-67 expression levels were determined via immunohistochemistry. Caspase 1 and GSDMD expression levels were determined via immunofluorescence assay. Furthermore, macrophage function and keratinocyte pyroptosis were also analyzed via flow cytometry. Cell proliferation was determined using 5-ethynyl-2ʹdeoxyuridine assay. SAL alleviated IMQ-induced psoriasis. IMQ-mediated GSDMD-driven pyroptosis and keratinocyte hyperproliferation promoted M1 macrophage polarization. However, SAL treatment suppressed GSDMD expression, thereby inhibiting keratinocyte proliferation and pyroptosis and promoting M2 macrophage polarization. GSDMD deficiency further promoted the effects of SAL and suppressed psoriasis progression. Overall, our findings suggest that SAL exerts protective effects against psoriasis. Specifically, it exerts anti-inflammatory effects by regulating M2 macrophage polarization and inhibiting keratinocyte pyroptosis-driven proliferation induced by the immune microenvironment in psoriasis.
牛皮癣是一种常见的与免疫相关的多基因炎症性皮肤病。皂甙(SAL)具有抗炎和抗氧化作用,可用于治疗皮肤病。然而,SAL 对银屑病的具体作用仍不清楚。本研究旨在探讨 SAL 对银屑病的治疗效果。用咪喹莫特(IMQ)治疗小鼠,建立体内银屑病模型。通过苏木精和伊红染色进行组织学分析。通过酶联免疫吸附试验测定细胞因子的释放。此外,还通过反转录定量聚合酶链反应测定了 mRNA 水平。蛋白质表达通过 Western 印迹法进行评估。Gasdermin D(GSDMD)和Ki-67的表达水平通过免疫组织化学法进行测定。Caspase 1和GSDMD的表达水平通过免疫荧光法测定。此外,还通过流式细胞术分析了巨噬细胞功能和角质形成细胞的热解。细胞增殖采用 5- 乙炔基-2ʹ脱氧尿苷测定法。SAL 可减轻 IMQ 诱导的银屑病。IMQ介导的GSDMD驱动的热蛋白沉积和角质细胞过度增殖促进了M1巨噬细胞的极化。然而,SAL 治疗抑制了 GSDMD 的表达,从而抑制了角质形成细胞的增殖和热蛋白沉积,促进了 M2 巨噬细胞的极化。GSDMD 的缺乏进一步促进了 SAL 的作用并抑制了银屑病的发展。总之,我们的研究结果表明,SAL 对银屑病具有保护作用。具体来说,它通过调节 M2 巨噬细胞的极化和抑制银屑病免疫微环境诱导的角质形成细胞脓毒症驱动的增殖来发挥抗炎作用。

This study presents a novel approach to manage vaginal infections due to Candidiasis, utilizing a novel silver secnidazole nano-hybrid emulsion (Ag-Secn-NHE)-based probiotics and free Ag-Secn-NHE. Ag-Secn-NHE was prepared by simple homogenization‒ultrasonication technique and validated by using a ultraviolet‒visible scan, dynamic light scattering, transmission electron microscopy (TEM), Fourier-transform infrared spectroscopy, and zeta potential. Saccharomyces cerevisiae (RCMB 002Y001) is the most effective probiotic-producing organism that demonstrates significant effects when combined with Ag-Secn-NHE. Ag-Secn-NHE-based probiotics showed significant antifungal effect compared to free Ag-Secn-NHE, silver nitrate, silver nanoparticles, secnidazole, secnidazole nanoemulsion, and commercial vaginal wash against multidrug-resistant vaginal pathogens. The highest inhibitory effect was achieved with Ag-Secn-NHE-based probiotic against Candida auris, Candida albicans, and Cryptococcus neoformans with minimal inhibitory concentration (MIC) 0.625 ± 0.002, 0.00625:1.25 ± 0.012 and 0.00625:1.25 ± 0.032 mg/mL, respectively, in comparison with Ag-Secn-NHE that show MIC at 0.00625:1.25 ± 0.612, 0.0125:2.5 ± 0.812, and 0.0125:2.5 ± 0.112 mg/mL (Ag:Secn). Ag-Secn-NHE-based- probiotic show minimum fungicidal concentration (MFC) at range from 2.5 to 20 mg/mL, wherever free Ag-Secn-NHE show MFC range from 5 to >20 mg/mL. Additionally, Ag-Secn-NHE-based probiotics have 75% inhibition of biofilm formation against C. auris and 60% inhibition of biofilm formation against both Cryptococcus neoformans and C. albicans in comparison with free Ag-Secn-NHE. Time-kill curves showed that the antifungal effect of Ag-Secn-NHE-based probiotics was fungistatic at 2MIC value after 4 h and after 16 h for Ag-Secn-NHE. TEM photographs showed that C. auris cells treated with Ag-Secn-NHE-based probiotic formula revealed severe deformations and distored ultrastructural changes. furthermore, results indicated that the Gamma radiation up to 15 kGy increases production of Ag-Secn-NHE in comparison with non-irradiated one.
本研究提出了一种治疗念珠菌性阴道炎的新方法,即利用新型瞬效唑纳米银杂化乳剂(Ag-Secn-NHE)为基础的益生菌和游离Ag-Secn-NHE。Ag-Secn-NHE 采用简单的均质-超声技术制备,并通过紫外-可见光扫描、动态光散射、透射电子显微镜(TEM)、傅立叶变换红外光谱和 zeta 电位进行了验证。酿酒酵母(RCMB 002Y001)是最有效的益生菌,与 Ag-Secn-NHE 结合使用时效果显著。与游离的 Ag-Secn-NHE、硝酸银、纳米银颗粒、昔尼达唑、昔尼达唑纳米乳剂和商用阴道洗液相比,基于 Ag-Secn-NHE 的益生菌对耐多药阴道病原体具有显著的抗真菌效果。基于 Ag-Secn-NHE 的益生菌对白色念珠菌、白色念珠菌和新生隐球菌的抑制效果最高,最小抑菌浓度(MIC)分别为 0.625 ± 0.002、0.00625 ± 0.002、0.00625 ± 0.002。002、0.00625:1.25 ± 0.012 和 0.00625:1.25 ± 0.032 mg/mL,而 Ag-Secn-NHE 的 MIC 为 0.00625:1.25 ± 0.612、0.0125:2.5 ± 0.812 和 0.0125:2.5 ± 0.112 mg/mL(Ag:Secn)。基于 Ag-Secn-NHE 的益生菌的最低杀菌浓度为 2.5 至 20 毫克/毫升,而游离 Ag-Secn-NHE 的最低杀菌浓度为 5 至 20 毫克/毫升。此外,与游离Ag-Secn-NHE相比,基于Ag-Secn-NHE的益生菌能抑制75%的阴沟球菌生物膜形成,抑制60%的新生隐球菌和白僵菌生物膜形成。时间杀伤曲线显示,基于 Ag-Secn-NHE 的益生菌的抗真菌效果在 4 小时后达到 2MIC 值,16 小时后达到 Ag-Secn-NHE 的 2MIC 值。TEM 照片显示,用 Ag-Secn-NHE 型益生菌配方处理的 C. auris 细胞出现了严重的变形和超微结构变化。

The objective of this article is to evaluate the salivary levels of tumor necrosis factor‐alpha (TNF‐α), interferon‐gamma (IFN‐γ), interleukin‐2 (IL‐2), and IL‐10 in patients with active psoriasis and compare them with those in healthy control subjects. This study included 60 subjects who were clinically diagnosed cases with active psoriasis (categorized further into 33 mild to moderate and 27 severe cases based on the Psoriasis Area Severity Index score) and 60 age‐ and gender‐matched healthy control subjects. Levels of TNF‐α, IFN‐γ, IL‐2, and IL‐10 in the unstimulated saliva of subjects were determined via enzyme‐linked immunosorbent assay (BT Lab). The salivary levels of TNF‐α, IFN‐γ, and IL‐2 were significantly higher, whereas IL‐10 concentration was significantly reduced in psoriatic patients in comparison to controls, and the difference increased with the progressing severity of the disease. Assessment of cytokine profiles in psoriasis patients is significant for diagnostic validation and monitoring the disease severity. Saliva offers an alternate, noninvasive, and readily available biological sample for evaluating cytokine levels. Extensive research in this field has been recommended for better scientifically proven conclusions.
本文旨在评估活动性银屑病患者唾液中肿瘤坏死因子-α(TNF-α)、γ干扰素(IFN-γ)、白细胞介素-2(IL-2)和IL-10的水平,并与健康对照组进行比较。这项研究包括60名经临床诊断为活动性银屑病的受试者(根据银屑病面积严重程度指数的评分进一步分为33名轻中度患者和27名重度患者),以及60名年龄和性别匹配的健康对照组受试者。受试者唾液中的 TNF-α、IFN-γ、IL-2 和 IL-10 水平通过酶联免疫吸附测定法(BT Lab)进行测定。与对照组相比,银屑病患者唾液中TNF-α、IFN-γ和IL-2的浓度明显升高,而IL-10的浓度则明显降低,且随着病情的加重,差异也随之增大。评估银屑病患者的细胞因子谱对于诊断验证和监测疾病严重程度具有重要意义。唾液为评估细胞因子水平提供了一种替代性、非侵入性和随时可用的生物样本。建议在这一领域开展广泛研究,以得出更科学的结论。

Currently, there exists conflicting data regarding the biological activity of unmodified fullerene C60. Various sources report its toxicity, geroprotective activity, and potential interaction with DNA. Contradictory findings regarding the toxicity of C60 may arise from the use of toxic solvents, as well as the influence of bioavailability and bioactivity on the preparation conditions of C60 suspensions. Furthermore, the microbiota of experimental animals can impact geroprotective activity results by releasing surfactants that facilitate substance penetration through the cell membrane. In this study, we selected conditions for solubilizing fullerene C60 in a solution of surfactin, a surfactant of bacterial origin, as well as in a 2% aqueous solution of TWEEN 80, employing ultrasound. Through bioluminescent analysis using lux biosensors in Escherichia coli MG1655, we observed that C60 in surfactin reduced induced genotoxic and oxidative stress. Given that surfactin enhances membrane permeability to fullerene C60, suspensions of fullerene in designated concentrations of surfactin can be regarded as a DNA protector and antioxidant, warranting further investigation as a promising component of novel drugs.
目前,有关未改性富勒烯 C60 生物活性的数据相互矛盾。各种来源都报道了它的毒性、老年保护活性以及与 DNA 的潜在相互作用。有关 C60 毒性的矛盾研究结果可能是由于使用了有毒溶剂,以及 C60 悬浮液的制备条件对生物利用率和生物活性的影响。此外,实验动物的微生物群会释放表面活性剂,促进物质穿透细胞膜,从而影响老年保护活性的结果。在这项研究中,我们利用超声波选择了富勒烯 C60 在表面活性素(一种源于细菌的表面活性剂)溶液和 2% TWEEN 80 水溶液中的增溶条件。通过在大肠杆菌 MG1655 中使用勒克斯生物传感器进行生物发光分析,我们观察到表面活性剂中的 C60 降低了诱导的基因毒性和氧化应激。鉴于表面活性剂能增强膜对富勒烯 C60 的渗透性,富勒烯在指定浓度的表面活性剂中的悬浮液可被视为一种 DNA 保护剂和抗氧化剂,值得进一步研究,有望成为新型药物的一种成分。
