Previously, we showed that the β-glucan curdlan suppressed osteoclastogenesis via binding to dectin-1, a pattern recognition receptor. Curdlan negatively regulates osteoclast differentiation and bone resorption capacity by suppressing the expression of nuclear factor of activated T cells 1 (NFATc1), a master factor for osteoclast differentiation, in a dectin-1-dependent manner; however, the mechanism involved in this process has not yet been fully elucidated. In this study, we aimed to elucidate the molecular mechanism involved in the suppression of RANKL-induced osteoclast differentiation by curdlan. Real-time RT-qPCR results showed that curdlan suppressed the expression of NFATc1 in cells of the osteoclast progenitor cell line RAW264.7 overexpressing dectin-1 (d-RAW cells), without altering the expression of negative regulators. Therefore, we examined the effect of curdlan on the NF-κB pathway, which is important for the induction of NFATc1 expression. Western blot analysis results showed that curdlan addition suppressed RANKL-induced NF-κB activation in the vector control line (c-RAW) cells with low expression of dectin-1, in d-RAW cells, and the parental RAW264.7 (RAW) cells. The results of tartrate-resistant alkaline phosphatase staining and real-time RT-qPCR showed that curdlan addition suppressed osteoclast differentiation in RAW cells, suggesting the presence of a dectin-1-independent modification system. Finally, we focused on the complement receptor 3 (CR3), which binds β-glucan, and revealed that blocking the binding of β-glucan to the CD11b molecule, a component of CR3, by neutralizing antibody, recovered the suppression of IκBα degradation by curdlan. These results suggest that the suppression of osteoclast differentiation by curdlan involves not only the dectin-1-dependent pathway but also the negative regulation of NFATc1 via modification of the NF-κB pathway via CR3 recognition. The results of this study may aid to establish treatment methods for metabolic bone diseases and inflammatory bone destruction and to clarify their pathogenesis.</p>\u0000 </div>","PeriodicalId":15219,"journal":{"name":"Journal of cellular biochemistry","volume":"126 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2024-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142739529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hyperoxia-treated type II alveolar epithelial cells (L2 cells) were used as the in vitro BPD model. CCK-8, flow cytometry, and reactive oxygen species (ROS) were used to evaluate cell viability. Fluorescence in situ hybridization confirmed the subcellular localization. Circ-ECH1 overexpression (or inhibited) and miR-708-5p mimics were used to investigate the roles of circ-ECH1 and miR-708-5p in BPD. Quantitative reverse-transcription polymerase reaction (qRT-PCR) detected the expressions of circ-ECH1, miR-708-5p, and neurotrophic receptor tyrosine kinase 2 (Ntrk2). Ntrk2 expression was evaluated by Western blot analysis. Changes in lung tissues were evaluated by hematoxylin and eosin staining. Pulmonary fibrosis was examined by Mason staining. TUNEL staining was performed to evaluate cell apoptosis in lung tissues. RNA sequencing was performed in the lung tissues of BPD rats. The binding between circ-ECH1 and miR-708-5p was confirmed through dual luciferase activity. Hyperoxia reduced cell viability and increased cell apoptosis and ROS accumulation. In addition, hyperoxia decreased the expression levels of circ-ECH1, which is mainly located in the cytoplasm. Circ-ECH1 overexpression increased cell viability but reduced cell apoptosis and ROS accumulation. On the contrary, interference with circ-ECH1 further promoted cell apoptosis and reduced cell activity. Furthermore, circ-ECH1 overexpression reduced the incidence of pulmonary fibrosis and lung cell apoptosis. RNA sequencing, followed by qRT-PCR, confirmed that the expressions of Ntrk2 and miR-708-5p were affected by circ-ECH1. miR-708-5p mimics reversed the role of circ-ECH1 in the BPD. Mechanistically, circ-ECH1 may bind with miR-708-5p to regulate Ntrk2 expression. Circ-ECH1 may compet with miR-708-5p to regulate Ntrk2 expression in BPD.

CLDN14 is highly expressed in human colorectal cancer (CRC) tissues and confers chemoresistance. CLDN14 may become a novel therapeutic target for CRC, but CLDN14-targeting drugs have not been developed. Here, we searched for a CLDN14-targeting peptide, which can suppress CLDN14 expression and chemoresistance using human CRC-derived DLD-1 and LoVo cells. Among some short peptides which mimic the second extracellular loop structure of CLDN14, PSGMK most strongly suppressed the protein expression of CLDN14. The mRNA expression of other endogenous TJ components was unchanged by PSGMK. The PSGMK-induced reduction of CLDN14 protein was inhibited by chloroquine, a lysosome inhibitor, and monodansylcadaverine, a clathrin-dependent endocytosis inhibitor, indicating that PSGMK may enhance endocytosis and lysosomal degradation of CLDN14. In a three-dimensional culture model, the oxidative stress was significantly reduced by PSGMK, whereas hypoxia stress was not. Furthermore, the expression levels of nuclear factor erythroid 2-related factor 2, an oxidative stress response factor, and its target genes were decreased by PSGMK. These results suggest that PSGMK relieves stress conditions in spheroids. The cell viability of spheroids was decreased by anticancer drugs such as doxorubicin and oxaliplatin, which was exaggerated by the cotreatment with PSGMK.

This study explores the effects of solasodine on regulating P-glycoprotein (P-gp) expression through the Nrf2/Keap1 signaling pathway and oxidative stress-induced sensitization of drug-resistant cancer cells to chemotherapeutics. Initially, the oxidative stress indicators such as intracellular ROS generation, the levels of 8-hydroxy-2-deoxyguanosine (8-OHdG) and gamma-H2AX (γ-H2AX) in the KBChR-8-5 drug-resistant cells were measured. Additionally, the protein expression levels of Nuclear factor erythroid 2-related factor 2 (Nrf-2), Kelch-like ECH-associated protein 1 (Keap1), and ATP Binding Cassette Subfamily B Member 1 (ABCB1)/P-gp were measured at various concentrations of solasodine (1, 5, &amp; 10 µM) through immunofluorescence and western blot analysis. The antioxidant activities in the KBChR-8-5 cells were assessed using established protocols. In this investigation, the treatment with solasodine and doxorubicin combination showed a notable increase in intracellular ROS generation in KBChR-8-5 cells. Furthermore, this combination treatment led to enhanced nuclear condensation, elevated levels of 8-OHdG, and increased γ-H2AX foci formation in the KBChR-8-5 cells. Solasodine treatment effectively inhibited the nuclear translocation of Nrf2 and activation of the <i>ABCB1</i> gene, consequently preventing overexpression of P-gp in KBChR-8-5 cells. Additionally, the combination therapy increased the lipid peroxidation levels while simultaneously reducing the activities of antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), and the levels of glutathione (GSH). These results demonstrated that solasodine disrupts redox balance, and overcomes drug resistance by downregulating P-gp via regulating Nrf2/Keap1 signaling pathway in MDR cancer cells.</p>\u0000 </div>","PeriodicalId":15219,"journal":{"name":"Journal of cellular biochemistry","volume":"126 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142620389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our study revealed the release time and anticancer potential of Shk on the SCC9 and H357 oral cancer cell lines. We investigated the antiproliferative, antimigratory, cell cycle arresting and apoptosis promoting activity of Shk in oral cancer cells by performing MTT and morphological assay, colony, and tumor sphere formation assay, AO/EtBr and DAPI staining, Annexin V-FITC/PI staining, assay for reactive oxygen species (ROS) and mitochondrial membrane potential (MMP) measurement, comet assay, qRT-PCR, and western blot analysis. We also checked the interaction of DNA and Shk by docking and CD spectroscopy and EtBr displacement assay. As a result, we found that Shk reduced the viability, proliferation, and tumorigenicity of SCC9 and H357 cells in a time and concentration-dependent manner. We obtained half-maximal inhibitory concentration (IC₅₀) at 0.5 µM for SCC9 and 1.25 µM for H357. It promotes apoptosis via overexpressing proapoptotic Bax and caspase 3 via enhancing ROS that leads to MMP depletion and DNA damage and arrests cells at the G2/M &amp; G2/S phase. The antimigratory activity of Shk was performed by analyzing the expression of markers of epithelial–mesenchymal transition like E-cadherin, ZO-1, N-cadherin, and vimentin.
