Abstract

Calcium‑dependent activator protein for secretion 1 (CAPS1) has been reported to promote metastasis in colorectal cancer (CRC), however, the underlying mechanisms have not yet been elucidated. The present study revealed that exosomes derived from CAPS1‑overexpressing CRC cells could enhance the migration of normal colonic epithelial FHC cells. GW4869, an inhibitor of exosomes, could attenuate the migration of FHC cells. Furthermore, liquid chromatography‑mass spectrometry (LC‑MS) and bioinformatics analysis demonstrated that overexpression of CAPS1 could alter the expression pattern of exosomal proteins involved in cell migration. Bone morphogenetic protein 4, which may serve vital roles in the process of CAPS1‑induced cell migration, was downregulated in the exosomes. In summary, the present results demonstrated that CAPS1 promotes cell migration by regulating exosomes. Inhibiting the secretion of exosomes may be helpful for the treatment of patients with metastatic CRC.
