This study reveals the regulatory role of tumor exosomes on cancer-associated fibroblast (CAF) in ovarian cancer, showing that ovarian cancer-derived exosomes can promote the proliferation and migration of CAF through the H19/miR-29c-3p/LOXL2-COL1A1 pathway, leading to tumor growth. This finding provides a theoretical basis for the development of therapeutic regimens targeting fibroblasts in ovarian cancer.
Cancer-associated fibroblast (CAF) is an essential risk factor for ovarian cancer. Exosomes can mediate cellular communication in the tumour microenvironment, but the interaction of tumour cell exosomes with CAF is less studied in Ovarian cancer. This study identified H19/miR-29c-3p/LOXL2-COL1A1 as a ceRNA regulatory network involved in regulating tumour matrix-associated signaling pathways associated with CAF. Cellular as-says demonstrated that exosomes from ovarian cancer cell line SKOV3 significantly promoted the proliferation and migration of CAF. The results of mixed transplantation tumour experiments in nude mice showed that exosomes of SKOV3 significantly promoted tumour growth. Ovarian cancer tumour-derived exosomes can regulate CAF proliferation and migration through H19/miR-29c-3p/LOXL2-COL1A1. This study reveals the regulatory role of tumour exosomes on CAF, which may provide a theoretical basis for the development of therapeutic regimens targeting fibroblasts in ovarian cancer.
