CNS region-specific gene expression patterns. (a) PCA of transcriptomes of the indicated CNS regions inclusive of all ages, diets and genders. The results show that each region of CNS has its own molecular signature that is independent of age, diet and gender. (b) PCA of transcriptomes of the CNS regions and non-CNS region (lung) inclusive of all ages, diets and genders.
