Exosomes from Fn-infected CRC cells promote tumor metastasis by selectively carrying miR-1246/92b-3p/27a-3p and CXCL16, Fn promotes CRC metastasis by regulating KRT7-AS/KRT7, and Fn promotes CRC development by activating the cytochrome P450 and epoxyoctadecenoic acid axes [11, 39, 40]. The gene discussed is KRT7; the disease is neoplasm.
