Abstract

Amyotrophic lateral sclerosis (ALS) is one of the most common adult-onset debilitating neurodegenerative diseases (NDs) which is characterized by a chronic progressive degeneration of upper and lower motor neurons, resulting in muscular atrophy, paralysis and ultimately death. It has been established that in ALS, the canonical Wnt/beta-catenin pathway is upregulated. Peroxisome proliferator-activated receptor gamma (PPAR gamma) generally varies in opposite way compared with the Wnt/beta-catenin signaling. Several studies carried out on ALS transgenic mice have shown the beneficial effects induced after treatment by PPAR agonists partly due to anti-inflammatory effects induced by PPAR gamma. The coupling between the Wnt/beta-catenin signaling and PPAR gamma has led to divide NDs into two classes: NDs in which the Wnt/beta-catenin pathway is upregulated whereas PPAR gamma is downregulated (ALS, Parkinson’s disease, Huntington’s disease and Friedreich’s ataxia); and NDs in which the Wnt-beta-catenin pathway is downregulated while PPAR gamma is upregulated (Alzheimer’s disease, bipolar disorder and schizophrenia).
