Comparing gene expression of Lentigo to perilesional normal. Comparing gene expression of Lentigo to perilesional normal

Analyze of gene expression of Lentigo and perilesional normal and compare gene expression of Lentigo to gene expression of perilesional normal. Overall design: We have 2 sample (two patient), we collected Lentigo and perilesional normal region in each patient, extract RNA and analyze exon array. We compare of gene expression of Lentigo and gene expression of perilesional normal.
