Summary |
Progressive myoclonus epilepsy of Unverricht-Lundborg type (EPM1) is an inherited neurodegenerative disease with myoclonus, seizures and ataxia, caused by the mutations in cystatin B (CSTB) gene. In an approach towards understanding the molecular basis of pathogenic events in EPM1 we have utilized the cystatin B deficient mice (Cstb-/-), a model for the disease. We have characterized the gene expression changes from the cerebellum of Cstb-/- mouse at postnatal day 7 (P7) and P30 as well as in cultured cerebellar granule cells using a pathway-based approach. A marked upregulation of immune response genes was seen at P30, reflecting the ongoing neuropathology, however, the observed alterations in complement cascade genes could also imply defects in synaptic plasticity. Differentially expressed genes in pre-symptomatic Cstb-/- animals at P7 were connected to synaptic function and plasticity and in cultured cerebellar granule cells to cellular biogenesis, cytoskeleton and intracellular transport. Especially GABAergic pathways were affected.
