Abstract

Infantile and juvenile neuronal ceroid lipofuscinosis (NCLs) are progressive neurodegenerative disorders of childhood with distinct ages of clinical onset, but with a similar pathological outcome. Infantile and juvenile NCL are inherited in an autosomal recessive manner due to mutations in the CLN1 and CLN3 genes, respectively. Recently developed Cln1- and Cln3-knockout mouse models share similarities in pathology with the respective human disease. Using oligonucleotide arrays we identified reproducible changes in gene expression in the brains of both 10-week-old Cln1- and Cln3-knockout mice as compared to wild-type controls, and confirmed changes in levels of several of the cognate proteins by immunoblotting. Despite the similarities in pathology, the two mutations affect the expression of different, non-overlapping sets of genes. The possible significance of these changes and the pathological mechanisms underlying NCL diseases are discussed.
