Transcriptomic and metabolic network analysis of metabolic reprogramming and IGF-1 modulation in SCA3 transgenic mice
Spinocerebellar ataxia type 3 (SCA3), also called Machado-Joseph disease (MJD), is a polyQ neurodegenerative disease that is still seeking cure. We used SCA-3 84Q transgenic mice as a disease model to study the therapeutic effect of insulin-like growth factor 1 (IGF-1). Transcriptomic and metabolomic profiles were established and compared  between the control (15Q), disease(84Q) and treatment(84Q+IGF-1) groups using RNA-seq and metabolic network analysis.  SCA3-84Q mice showed a decrease in glycolysis, lipolysis and mitochondrial oxidative phosphorylation, and an increase in apoptosis, and IGF-1 treatment reversed the alterations slightly. Overall design: RNAseq analysis of cerebellar tissue from three groups of mice, each group contains 3 replicates. 15Q mice are used as control samples, 84Q mice are disease samples and 84Q mice treated with IGF1 are belong to treatment samples.
