Phillygenin is an effective component of <i>Forsythiae fructus</i> that has long been used in cancer therapy. The mechanism by which phillygenin regulates the TME remains unknown. Methods and Results: A co-culture system of CRC cells and Jurkat T cells was used to simulate the TME <i>in vitro</i>. Network pharmacology and Human XL cytokine arrays were used to preliminarily evaluate the role of phillygenin in the TME. The target of phillygenin was determined using transfection of plasmid-producing overexpression of hypoxia-inducible factor 1 alpha (HIF-1α) overexpression or abrogated HIF-1α expression via short hairpin RNA plasmid. The therapeutic effect of phillygenin <i>in vivo</i> was assessed in a subcutaneous tumor mouse model. <i>In vitro</i>, phillygenin enhanced the immune response of T cells and prevented the immune escape of cancer cells via the inhibition of HIF-1α. Phillygenin upregulated interleukin (IL)-2 and downregulates IL-10 and FOXP3 in Jurkat T cells co-cultured with CRC cells. Phillygenin inhibited expressions of HIF-1α, transforming growth factor-beta, vascular endothelial growth factor, and CD31 in CRC cells cultured alone or with Jurkat T cells. Phillygenin considerably suppressed tumor growth and improved the TME <i>in vivo</i>. Conclusions: Phillygenin can enhance the immune response and inhibit angiogenesis in the TME in CRC by inhibiting HIF-1α.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s10616-024-00679-2.</p>","PeriodicalId":10890,"journal":{"name":"Cytotechnology","volume":"77 1","pages":"17"},"PeriodicalIF":2.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11631830/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142817505","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These results indicate that pH has a strong influence on the antitumor activity of CTX-XII, likely due to pH-dependent ionization changes in CTX-XII that increase its affinity for and penetration into tumor cell membranes.

Based on this, here we studied the role of CTLA-4 silencing by specific siRNA in MCF-7 breast cancer cell line together with Docetaxel treatment which is one of the robust chemotherapy agents to demonstrate the significance of combining chemotherapy with efficient targeted therapy in tumor regression. The MCF-7 breast cancer cell line was transfected with CTLA-4-siRNA through the electroporation method, then received an appropriate dose of Docetaxel determined by MTT assay.

The previous study demonstrated that IBS008738, the activator of TZA, was able to enhance myogenesis in mouse myogenic C2C12 cells, prevent dexamethasone-induced muscle atrophy, and facilitate muscle repair in cardiotoxin-induced muscle injury. Accordingly, our study was designed to probe into the potential role of IBS008738 in muscle damage in mouse models induced by high-intensity exercise. Mice were first administrated with IBS008738, and then subjected to high-intensity eccentric exercise to induce muscle damage after 24 h. During the experiment, mouse weight change and food take were recorded. At the end of the experiment, blood samples were collected through cardiac puncture and centrifugated. Serum levels of blood urea nitrogen (BUN), creatinine, glucose, lactate dehydrogenase (LDH), creatinine kinase (CK), and C-related protein were evaluated using an autoanalyzer. After mice were sacrificed, the gastrocnemius muscles were dissected for DCFH-DA assay of ROS generation, thiobarbituric acid-reactive substances (TBARS) assay of MDA content, hematoxylin-eosin (H&E) staining of histological examination, and western blotting analysis of Akt/mTOR/S6K1 signaling expression. IBS008738 and/or exercise exert significant effects on mouse weight and food take. High-intensity exercise markedly increased ROS generation and lipid peroxidation, upregulated serum levels of CK, LDH, and C-related protein, ameliorated muscle histological damage, and reduced TAZ, phosphorylated (p)-Akt, p-mTOR, and p-S6K1 protein levels in mice. However, IBS008738 administration reversed the above changes induced by high-intensity exercise in mice. IBS008738 alleviates oxidative stress and muscle damage in mice after high-intensity exercise by activating TAZ and the Akt/mTOR/S6K1 signaling pathway.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s10616-024-00667-6.</p>","PeriodicalId":10890,"journal":{"name":"Cytotechnology","volume":"77 1","pages":"2"},"PeriodicalIF":2.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11576750/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142686022","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we examined the effects of donor age and cell expansion on ASC characteristics and transcriptome using ASCs obtained from three young and three old donors. Cell expansion significantly impaired stem cell properties, notably reducing proliferation and differentiation capacities. In contrast, donor age had minimal effects on ASCs. RNA sequencing (RNA-seq) revealed differences in gene expression related to stemness, phagocytosis, and metabolic processes influenced by cell expansion. To investigate miRNA variability, we performed small RNA-seq on sEVs collected from ASCs of all six donors. The miRNA profiles were influenced by donor age and cell passage. Interestingly, functional enrichment analysis indicated that advanced donor age and increased cell passage may enhance the production of miRNAs associated with organ development through various pathways.

However, large-scale in vitro expansion is necessary to obtain enough cells for therapeutic purposes. Therefore, this study aimed to optimize cell culture conditions and determine the characteristics of expanded WJ-MSCs. WJ-MSCs were seeded in 6-well plates at a density of 5000 cells/cm<sup>2</sup> and cultured with different mediums, including DMEM-LG+10% FBS, DMEM-LG+10% HPL, serum-free commercial medium 1, serum-free GMP grade commercial medium 2, and HPL supplemented commercial medium 3.

WJ-MSCs were then cultured in the selected mediums at seeding densities ranging from 1000 to 5000 cells/cm<sup>2</sup>, and cell growth kinetics were analysed. WJ-MSCs cultured in the selected mediums were characterized by their immunophenotype, tri-lineage differentiation potential and immunosuppression property. WJ-MSCs cultured with DMEM-LG+10% HPL, commercial medium 1 and commercial medium 2 showed smaller size, significantly higher cell yield, and shorter population doubling time than those cultured in other mediums.

In summary, DMEM-LG+10% HPL is the best medium for WJ-MSC expansion, as it provides the highest cell yield without compromising cell characteristics and functionality.
