{"title":"Effects of Ursolic Acid in Extracts of <i>Prunella vulgaris</i> on the Proliferation of Thyroid Papillary Carcinoma Cells Under the p53MAPK Signaling Pathway","authors":"Chao Hu, Qi Zhang, Dongxian Liu, Chao Li, Ming Li","doi":"10.1166/sam.2023.4520","DOIUrl":"https://doi.org/10.1166/sam.2023.4520","url":null,"abstract":"The aim of this research was to demonstrate the impact of ursolic acid (UA) in Prunella vulgaris extracts on the proliferation of papillary thyroid carcinoma (PTC) cells through the p53MAPK signaling. Effects of Prunella vulgaris extracts on TPC-1 cell proliferation were analyzed by intervening with various concentrations of UA, including negative control (NC) group, solvent control (SC) group, 3 μ M UA group, 6 μ M UA group, 12 μ M UA group, and 15 μ M UA group. Flow cytometry was adopted to evaluate apoptosis in TPC-1 cells, while real-time fluorescent quantitative (RT-q) PCR was implemented to assess expression (EP) of Bax and Bcl-2 in TPC-1 cells following UA intervention. RT-qPCR and Western blotting were employed to examine the differential EP levels of cell apoptosis, Bax, and Bcl-2 proteins. RT-qPCR was utilized to investigate the influence of UA on EP of various genes in MAPK pathway. The ethyl acetate extract exhibited the most notable inhibitory effect on TPC-1 cells. The content of UA in Prunella vulgaris increased gradually with the extension of ultrasonic time. The growth curve of TPC-1 cells demonstrated an initial increase followed by a decrease with increasing time. As the concentration increased, cell proportion in S phase increased, while the proportions in the GO-G1 and G2-M phases decreased, indicating that UA concentration-dependently arrested cells in the S phase. The level of Bax mRNA exhibited an increasing trend with increasing concentration, and the 12 μ M UA and 15 μ M UA groups demonstrated remarkable differences versus NC group ( P <0.01). Bcl-2 protein demonstrated a decreasing trend with increasing concentration, and the 6 μ M UA, 12 μ M UA, and 15 μ M UA groups exhibited considerable differences relative to NC group ( P < 0.05). Additionally, pro-apoptotic protein Bax increased, while that of anti-apoptotic protein Bcl-2 decreased. UA treatment upregulated EP of the p53 gene in the MAPK pathway. Genes such as ERK, MEK, TSHR, Ras, p53, BRAF, PAK4, and PAKCa were downregulated. In summary, UA can upregulate EP of the p53 gene in the MAPK pathway, greatly inhibit proliferation of TPC-1 cells in PTC, and promote apoptosis. These findings provide insights for therapy of thyroid cancer.","PeriodicalId":21671,"journal":{"name":"Science of Advanced Materials","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135736319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We identified differentially expressed genes (DEGs) between OSCC and control samples and intersected them with telomere-related genes. Three risk model genes (IGF2BP2, EIF5A2, and PLOD2) were obtained through Cox and LASSO analyses. A risk model was constructed based on the expression of these genes. The OSCC samples were divided into high and low-risk groups using the median risk score. Univariate and multivariate Cox analyses identified risk score and age as independent prognostic factors. Gene set enrichment analysis revealed enrichment in chemical stimulus and appendage development pathways. We constructed a transcription factor (TF)-mRNA network involving two mRNAs (EIF5A2, PLOD2) and 17 TFs, including STAT1-EIF5A2 and TEAD1-EIF5A2. Immune-infiltration analysis showed significant differences in the abundance of 11 immune cells between the high and low-risk groups, including T cells CD8, activated mast cells, and macrophages M0. Our findings contribute to the development of a telomere-related risk model (including IGF2BP2, EIF5A2, and PLOD2) for predicting the prognosis of OSCC, providing new insights for further studies in this area.","PeriodicalId":21671,"journal":{"name":"Science of Advanced Materials","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135736560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The thermal expansion coefficient of the porous carrier for negative thermal expansion materials was examined, and modifications were made to the material used for snow melting and ice suppression. In conclusion, the researchers successfully developed snow melting and ice suppression materials with low thermal expansion that met the desired performance criteria. Furthermore, they conducted an analysis of the precipitation rate, as well as the snow melting and ice suppression effectiveness of these materials across various temperature ranges. According to the results, the thermal expansion coefficient of the carrier Z1 is positive and varies slightly in the temperature range of −30 °C~−10 °C. In the temperature range of −10 °C~0 °C, the thermal expansion coefficient is negative, and it has negative thermal expansion characteristics. At 0 °C~60 °C, its thermal expansion coefficient first increases and then decreases. In the low temperature stage, the amount of salt precipitation decreases with the decrease of temperature. In the conductivity test, the conductivity at 0 °C is greater than that at −5 °C, and much greater than that at 10 °C, the presence of a negative thermal expansion coefficient has been observed to exert a specific influence on the precipitation of materials used for snow melting and ice suppression. In addition, with the increase of temperature, the amount of salt precipitation increases. Whereas, when the temperature is higher than 35 °C, due to the thermal expansion characteristics of the carrier, the expansion of the volume of snow melting and ice suppression materials is comparatively limited, which results in a not greatly increased precipitation rate of the snow melting and ice suppression components compared with that at 35 °C.","PeriodicalId":21671,"journal":{"name":"Science of Advanced Materials","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135736313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Clarithromycin is a well-known macrolide antibiotic that is commonly used for the treatment of a wide variety of bacterial infections. However, extensive preclinical and clinical studies have recently revealed the efficacy of clarithromycin in treating various tumors in combination with conventional therapy. In this study, we formulated a clarithromycin nanoemulsion using pumpkin seed oil as a natural nano-carrier to study the possible cytotoxic effects against colorectal (HCT 116), breast (MCF-7), and liver cancer (HepG2) in vitro . The formulated nanoemulsion was characterized for droplet size distribution, surface charge, drug loading and in vitro drug release. The droplet size of clarithromycin nanoemulsion was 360.6±42.5 nm and zeta potential was −31.6± 2.8 mV. Incorporating the lipophilic drug, clarithromycin, within nanoemulsion significantly heightened in vitro drug release, compared to plain drug. The anticancer properties of the nanoemulsion formulation were examined using sulforhodamine B (SRB) assay as well as cell cycle and apoptosis analyses. Clarithromycin-loaded pumpkin seed oil-based nanoemulsion remarkably diminished the viability of all tested cell lines, compared to either plain clarithromycin or plank pumpkin seed oil nanoemulsion. In addition, incorporating clarithromycin within pumpkin seed oil-based nanoemulsion synergistically augmented the cytotoxic efficacy of clarithromycin against various cancer cell lines via advocating considerable cell cycle arrest with subsequent elicitation of potent apoptotic response. These results support the potential use of clarithromycin in cancer therapy, and merit future translational research.","PeriodicalId":21671,"journal":{"name":"Science of Advanced Materials","volume":"2 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135736317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The TCMSP platform was used to select active ingredients and targets of LGZGD based on drug ADME properties, forming a component-target network. Obesity-related targets were identified from various databases, and a global network was constructed to analyze interactions between components, targets, and disease-related proteins. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were conducted using G: profiler. Molecular docking using AutoDockTools validated the binding of key active components to core targets. The study identified 120 active ingredients and 201 targets for LGZGD, with 84 targets related to obesity. GO analysis revealed various biological processes, cellular components, and molecular functions associated with obesity, including lipid response and cellular response to chemical stimuli. KEGG pathway analysis highlighted signaling pathways such as AGE-RAGE signaling in diabetic complications, cancer pathways, IL-17 signaling, and neuroactive ligand-receptor interaction signaling. Molecular docking confirmed that the core active components of LGZGD tightly bind to key targets involved in obesity treatment. This study provides a preliminary understanding of the pharmacological basis and efficacy mechanism of LGZGD in treating obesity, supporting its traditional use and offering a theoretical foundation for further research.","PeriodicalId":21671,"journal":{"name":"Science of Advanced Materials","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135736321","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
