Gene expression profile of acupuncture treatment in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine-induced Parkinson's disease model
2010
Abstract Objectives: To find new biomarkers by stimulating acupuncture point GB34 (Yangneungcheon) which has neuroprotective effect on the mouse model of Parkinson's disease, analysis of cDNA microarray on mRNAs of the substantia nigra was performed. Methods: Male C57BL/6 mice were divided into two groups: 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine-treated mice (MPTP group, n=3); 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine and acupuncture (GB34)-treated mice (MPTP + ACU group, n=3). The mice received an intraperitoneal injection of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (30 mg/kg) once daily for 3 consecutive days. Manual acupuncture was performed 2 hours after every injection of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine. The total RNA in the substantia nigra of each mouse was isolated on 3 days after the last 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine injection. Agilent mouse whole genome 44K chip was used for microarray analysis and the hybridization image was analysed by GenePix Pro 6.0. ...
