Parkinson's disease(PD) is a neurodegenerative disorder characterized clinically by
bradykinesia. rigidity, tremor, and pathologically by neuronal cell death in substania
nigra. The cause of dopaminergic neuronal cell death in PD remains unknown.
Recently, decreased mitochondrial complex I activities have been reported in platelets.
muscles. substantia nigra of the PD Patients.
Blood samples were lysed with lysis buffer, and incubated 1 hour with 200mh/ml
proteinase K at 37¡É. DNA was extracted with phenol and chloroform (1:1). The long
and accurate polymerase chain reaction (LA PCR) was performed by mitochondrial
specific primers. The mitochondrial ND 1, ND 2, CO ¥°, CO ¥±, and 1/3ATPase 6/8, CO
¥². genes as well as parts of ND3 and 3/4ND5 subunit coding regions were analysed by
LA PCR. In this study, it is observed not only 4,997 bp mtDNA deletion but a partial
mtDNA deletion of the ND1, ND2, Co ¥°¡­¥² genes in blood from patients with PD.
The results of this study cannot rule out the possibility of point mutation. It is possible
that such a deletion would cause mitochondrial dysfunction, and as a result of
mitochondrial dysfuction. Parkinson's disease could progress.
