ABSTRACT

Mitochondria in cancer have genetic instability like genetic mutations or polymorphisms, and D-loopis hot spot region and is suggested its association with cancer prognosis. Genetic variations of D-loop were associatedwith mitochondrial copy number. In present study, mitochondrial polymorphism in D-loop (D310 and D514)was studied in 108 DNAs from health individuals and its association with mitochondrial copy number was alsoinvestigated. In D310 polymorphism, C7 was most common (37.7%, 40/108), and C8 and C9 was found in 32.1%and 30.2%, respectively. In D514 polymorphism, (CA)5 and (CA)4 was shown in 61.4% and 38.6%, respectively. Mitochondrial copy number was increased in 40.7% while it was decreased in 59.3%. There was no associationbetween mitochondrial polymorphism and copy number. Follow-up study should be needed to confirm its changein same individuals.
