Abstract (original English)
Background Radiation resistance limits radiotherapy efficacy in esophageal squamous cell carcinoma (ESCC). The tumor microenvironment, particularly adipocytes, plays a role in promoting cancer progression. Extracellular vesicles and microRNAs (miRNAs) regulate gene expression and hold prognostic potential for esophageal carcinoma. Elucidating radioresistance mechanisms and identifying radiosensitization targets can help enhance radiotherapy efficacy for esophageal cancer. Aim To investigate the potential role of miRNAs derived from adipocyte exosomes as prognostic markers for radiotherapy efficacy in ESCC. Methods Free adipocytes were isolated from human thoracic adipose tissue. A co-culture model of adipocytes and ESCC cells was established to observe colony formation and cell survival post-irradiation. ESCC cell apoptosis was assessed by flow cytometry. Western Blot and immunofluorescence assays were performed to evaluate DNA damage in ESCC cells post-irradiation. Adipocyte-derived exosomes were isolated by ultracentrifugation and identified by electron microscopy. A similar set of experiments was performed on ESCC cells to analyze cell survival, apoptosis, and DNA damage post-radiation exposure. Exosomes from adipose tissue and serum exosomes from ESCC patients pre- and post-radiotherapy were subjected to high-throughput miRNA-sequencing and validated using real-time quantit
