Exosomal ANXA1 derived from thyroid cancer cells is associated with malignant transformation of human thyroid follicular epithelial cells by promoting cell proliferation.

ABSTRACT: Exosomes are nano‑sized extracellular vesicles that can be released from cancer cells. It has been shown that cancer cell‑derived exosomes may be associated with carcinogenesis by transferring signaling proteins from malignant to neighboring non‑malignant cells. In addition, annexin A1 (ANXA1) is a well‑known oncogene, that can be released from extracellular vesicles by cancer cells. However, the role of exosomal ANXA1 in the cell‑to‑cell communication of thyroid cancer and thyroid follicular epithelial cells remains unclear. In the present study, the protein expression levels of ANXA1 in thyroid cancer cells and thyroid cancer cell‑derived exosomes were analyzed using western blot analysis. In addition, Cell Counting Kit‑8 and Transwell assays were used to determine cell viability and inv
