MT-CO1 and ovarian carcinoma: In this study, we analyzed sequence variants in two regions of mtDNA obtained from 118 epithelial ovarian cancer and 18 matched paracancerous normal tissues spanning 5317 to 7608 and 8282 to 10110 bp, including ND subunits 2 and 3; MT-COI, II, and III; ATPase 8; part of ATPase 6; and tRNA genes.
