Abstract Background Magnetic fluid hyperthermia (MFH) represents a promising therapeutic strategy in cancer utilizing the heating capabilities of magnetic nanoparticles when exposed to an alternating field (AMF). Because efficacy and safety MFH treatments depends on numerous intrinsic extrinsic factors, therefore, proper setups should focus thermal energy dosed into cells. Methods In this study, we performed experiments using human lung A549 cells (in vitro) NUDE Balb/c mice bearing (A549) vivo). these two experimental models, heat was induced by magnesium-doped iron(III) oxide coated with mPEG-silane (Mg 0.1 -γ-Fe 2 O 3 (mPEG-silane) 0.5 ) AMF.

Cancer stem cells (CSCs) play a central role in tumor progression, recurrence, and resistance to conventional therapies, making them critical focus oncology research. This review provides comprehensive analysis of CSC biology, emphasizing their self-renewal, differentiation, dynamic interactions with the microenvironment (TME). Key signaling pathways, including Wnt, Notch, Hedgehog, are discussed detail highlight potential as therapeutic targets. Current methodologies for isolating CSCs critically examined, addressing advantages limitations advancing precision medicine. Emerging technologies, such CRISPR/Cas9 single-cell sequencing, explored transformative unraveling heterogeneity informing strategies. The also underscores pivotal TME supporting survival, promoting metastasis, contributing resistance. Challenges arising from CSC-driven dormancy analyzed, along strategies mitigate these barriers, novel therapeutics targeted approaches. Ethical considerations integration artificial intelligence designing CSC-specific therapies essential elements future manuscript advocates multi-disciplinary approach that combines innovative advanced therapeutics, collaborative research address complexities CSCs. By bridging existing gaps knowledge fostering advancements personalized medicine, this aims guide development more effective cancer treatment strategies, ultimately improving patient outcomes.

Abstract Oleanolic acid (OA) has demonstrated anticancer effects across various cancers, with some derivatives advancing to clinical trials. Howe ver, its precise mechanisms of action remain unclear, especially in oral squamous cell carcinoma (OSCC). This study employed network pharmacology, bioinformatics, molecular docking, dynamics simulations, and experimental validation explore OA’s OSCC elucidate mechanism action. pharmacokinetic physicochemical properties were assessed using SwissADME Molsoft, revealing high bioavailability GI absorption. SwissTargetPrediction SuperPred identified protein targets, whereas GeneCards provided OSCC-related targets. A Venn diagram showed 34 overlapping targets between OA OSCC. STRING Cytoscape used construct a protein-protein interaction (PPI) 32 nodes 164 edges, identifying HSP90AA1, STAT3, HSP90AB1, PI3KR1, NFKB1 as key hub genes. Gene ontology KEGG enrichment analyses highlighted relevant biological processes, functions, pathways. Molecular docking simulations confirmed the strong binding Experimental that inhibited viability colony formation dose-dependent manner, induced apoptosis, downregulated PI3KR1 proteins. In conclusion, this comprehensive combining assays provides valuable insights into potential detailed
