Abstract Objectives: Metastatic spread to the lung is one of the leading causes of fatal outcomes in thyroid cancer, but the underlying molecular mechanisms remain unclear. To investigate how exosomal microRNA-17-5p (miR-17-5p) promotes lung metastasis in thyroid cancer within the framework of the “seed and soil” hypothesis. Methods: Serum exosomes from thyroid cancer lung metastasis patients and controls were analyzed for miR-17, which was elevated in metastatic cases. miR-17 was transfected into embryonic lung fibroblasts (MRC-5), and their supernatants were co-cultured with thyroid cancer cells (Cal62). Cell proliferation and migration were evaluated using colony formation, Ki67… More >
