Targeting MDM2 affects spastin protein levels and functions: implications for HSP treatment by Francesca Sardina, Federica Polverino, Sonia Valentini, Claudia Carsetti, Elisabetta Falvo, Giada Tisci, Silvia Soddu, Fabiola Moretti, Alessandro Paiardini, Cinzia Rinaldo

“…By biochemical and functional experiments, we demonstrate that MDM2 binds spastin and regulates its levels in a post-transcriptional manner independently of the E3 ubiquitin ligase activity. Of relevance, treatment of spastin-deficient cells with the MDM2 inhibitor Nutlin-3a can restore spastin levels and functions, such as cytokinetic abscission and sorting of transferrin receptor. …”

Therapeutic Potential of α-Synuclein Evolvability for Autosomal Recessive Parkinson’s Disease by Jianshe Wei, Gilbert Ho, Yoshiki Takamatsu, Eliezer Masliah, Makoto Hashimoto

“…The majority of Parkinson’s disease (PD) is sporadic in elderly and is characterized by α-synuclein (αS) aggregation and other alterations involving mitochondria, ubiquitin-proteasome, and autophagy. The remaining are familial PD associated with gene mutations of either autosomal dominant or recessive inheritances. …”
