Furthermore, to investigate the involvement of MAMs in atherosclerosis pathogenesis, we examined the expression of three core MAMs-related molecules—Mitofusin 1 (MFN1), Mitofusin 2 (MFN2), and Mitochondrial Fission 1 (Fis1)—in the same PBMC samples. The gene discussed is MFN2; the disease is atherosclerosis.
