Substantia nigra pars compacta (SNpc) is highly sensitive to normal aging and selectively degenerates in Parkinson's disease. However, ventral tegmental area (VTA), a region adjacent to SNpc, is less affected in PD. Until now, molecular mechanisms behind VTA aging have not been fully investigated using high throughput techniques. Here, aging-associated early changes in transcriptome of VTA were investigated comparing late middle-aged (18 months old) to young (2 months old) mice. Three age groups of C57 wild type mice were used in microarray analysis: young (2 months old), middle aged (10 months old), and late-middle aged (18 months old) mice. Four replicates were included in each age group and each replicate was pooled from 5 mice (5 mice/replicate x 4 replicates x 3 age groups). Total RNA was isolated from VTA for hybridization on Affymetrix microarrays.
