An in vitro model was constructed by osteogenic differentiation-induced stimulation (OS) on the hFOB1.19 cell line. Real-time fluorescence quantitative PCR (RT-qPCR) was performed to detect the expression of NR2F1-AS1, miR-423-5p and osteogenic differentiation markers (RUNX2, OCN, OPN). Cell Counting Kit-8 (CCK8) method and flow cytometry were observed cell proliferation and apoptosis, respectively. Enzyme linked immunosorbent assay (ELISA) tested alkaline phosphatase (ALP) activity. Dual-Luciferase Report (DLR) assay and RNA immunoprecipitation (RIP) verified gene interactions. Bioinformatics methods predicted downstream target genes and their pathways of action. OS increased osteogenic differentiation markers and NR2F1-AS1 expression and decreased miR-423-5p levels. Transfection of si- NR2F1-AS1 promoted OS osteoblast apoptosis, but inhibited cell proliferation, ALP activity and osteogenic differentiation marker expression. NR2F1-AS1 is mostly present in the cytoplasm and is involved in the osteogenic differentiation process by down-regulating miR-423-5p. The use of miR-423-5p inhibitor can resist apoptosis induced by silencing NR2F1-AS1, promote osteoblast proliferation, activate ALP activity, and induce osteogenic differentiation process in osteoblasts. Bioinformatics prediction identified 82 target genes that might be involved in osteogenic differentiation, and Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis suggested that they were mainly associated with inter-synaptic formation and signaling.

Aldehyde dehydrogenase 1A1 (ALDH1A1), a cytosolic enzyme, shows vital physiological and pathophysiological functions in many areas. In the majority of cancer types, obesity-associated protein (FTO) is upregulated and exhibits an essential tumor-promoting role. We speculate that FTO and ALDH1A1 may play a significant role in the pathogenesis of PE by affecting the trophoblast cell biological behaviors. We analyzed differential expression genes (DEGs) in PE and non-PE groups in the GSE234726 dataset. The reverse-transcription quantitative polymerase chain reaction (qRT-PCR) and western blot assay were performed to test the mRNA and protein levels. The cell proliferation and apoptosis were examined using 5-Ethynyl-2'-deoxyuridine (EdU) and flow cytometry. The cell migration was investigated by wound healing assay and transwell assay. The ability of angiogenesis was tested by angiogenesis assay. The Spearman's rank correlation coefficient was used to analyze the correlation between ALDH1A1 expression and FTO expression. The m6A methylation site of ALDH1A1 mRNA was predicted using SRAMP website. The RNA immunoprecipitation (RIP) and m6A RNA immunoprecipitation (MeRIP) assay were performed to examine the binding relationship between ALDH1A1 and FTO. In PE, ALDH1A1 level is decreased. Silencing ALDH1A1 suppressed cell proliferation, migration, and angiogenesis and induced cell apoptosis. ALDH1A1 knockdown inhibited the expression of cyclin D1, anti-matrix metalloproteinase 9 (MMP9), and vascular endothelial growth factor (VEGF) and facilitated c-casp3 levels. The FTO expression was increased in PE placentas. Besides, the ALDH1A1 expression was negatively correlated with FTO levels, and FTO could target ALDH1A1. Mechanically, FTO repressed the biological behaviors of HTR-8/SVneo cells via ALDH1A1 down-regulation. FTO retards the HTR-8/SVneo cell biological function through knockdown of ALDH1A1.

The purpose of this study was to explore the role and mechanism of ELF3 in regulating EC progression. In this study, we collected 8 pairs of EC tissue and normal paracancerous endometrial tissue, and injected human endometrial cancer cells (Ishikawa) into the left axilla of nude mice to construct a model of subcutaneous tumorigenesis in nude mice.

In this study, it was found that the expression of ELF3 was up-regulated in EC, and knockdown of ELF3 could inhibit the proliferative activity and colony formation of EC cells, promote the expression of E-cadherin, inhibit the expression of N-cadherin and Vimentin, and reduce the epithelial-mesenchymal transition (EMT) of EC cells, thereby inhibiting the migration of EC cells to a certain extent and alleviating the development of EC in vivo. Mechanistically, ELF3 inhibits TPM1 transcription by binding to the promoter region of TPM1 gene, thereby inhibiting TPM1 expression, promoting EMT, proliferation and migration of EC cells, and accelerating the occurrence and development of EC in vivo.

Characterisation techniques confirmed the synthesis of CEGSTNs and CEGSSNs. Both exhibited significant anticancer activity, induced apoptosis, and downregulated SKA3 expression, which inactivated the PI3K/AKT/mTOR pathway in HeLa cells. Acute toxicity analysis showed no toxicity or adverse effects in the treatment group. Overall, these results suggested that CEGSTNs have exhibited more anticancer efficacy than CEGSSNs.

Four primary hPDLSC populations-two with high osteo/cementogenic potential (HOP) and two with low potential (LOP)-were cultured under standard (SDM) and osteo/cementogenic (OM) conditions. Mineralization was assessed using Alizarin Red Staining (AR-S) and alkaline phosphatase (ALP) activity, while gene expression of ASPN, BMP2, osteocalcin (OCN), and runt-related transcription factor 2 (RUNX2) was quantified by quantitative real-time polymerase chain reaction (qRT-PCR). BMP2 protein levels were measured using the Luminex system. Data analysis incorporated Principal Component Analysis (PCA), Linear Discriminant Analysis (LDA), Pearson correlations, correlation networks, and multivariate regression models in RStudio.

Here, a comprehensive study is presented to investigate the impact of potentially critical process parameters (aeration rate, agitation speed, dissolved oxygen level and copper concentration) on process performance and CQAs. Results demonstrated that dissolved oxygen level has a dominate positive effect on lactate consumption. Scale-relevant parameters (aeration rate and agitation speed) and copper concentration have smaller but also significant positive influence on lactate consumption. Based on these results, it can be summarized that low dissolved oxygen, agitation and aeration rates plus low copper concentration, would lead to insufficient oxygen availability for cell respiration (hypoxia). Under this condition, cells would rely on anaerobic glycolysis to generate energy and hence promote lactate production. This study also revealed a linkage between hypoxic condition and antibody purity and charge heterogeneity.

However, whether sevoflurane affects the metastasis of small cell lung cancer (SCLC) cells remains unexplored. This study's primary objective was to investigate the mechanism by which sevoflurane induces calcium overload and EFHD1 upregulation, thereby contributing to pyroptosis in SCLC cells. NCI-H446 cells were treated with sevoflurane at concentrations of 0%, 0.6%, 3% and 15%. Cell proliferation was assessed using the CCK8 assay, while cell migration and invasion were analyzed using the Transwell assay. EFHD1 expression was determined by q-PCR and Western blot. Calcium content, ROS levels, and CCO content were measured using respective assay kits, and mitochondrial morphology was observed using transmission electron microscopy. Western blotting was performed to detect the expression of caspase-1 and GSDMD. All procedures were repeated under conditions of EFHD1 overexpression or silencing. Sevoflurane inhibited the proliferation, migration, and invasion of NCI-H446 cells, concurrently exerting a significant pro-pyroptotic effect. This was mediated by mitochondrial calcium overload, EFHD1 upregulation, and subsequent mitochondrial damage-induced pyroptosis. Sevoflurane significantly enhances pyroptosis in NCI-H446 cells, thereby potentially reducing cancer cell dissemination during surgery.</p>","PeriodicalId":10890,"journal":{"name":"Cytotechnology","volume":"77 4","pages":"150"},"PeriodicalIF":2.0,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12271033/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144674098","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}
