ULK overexpression mitigates motor deficits and neuropathology in mouse models ...
Vasconcelos-Ferreira, Ana; Martins, Inês Morgado; Lobo, Diana; Pereira, Dina; Lopes, Miguel M.; Faro, Rosário; Lopes, Sara M.; Verbeek, DinekeMachado-Joseph disease (MJD) is a fatal neurodegenerative disorder clinically characterized by prominent ataxia. It is caused by an expansion of a CAG trinucleotide in ATXN3, translating into an expanded polyglutamine (polyQ) tract in the ATXN3 protein, that becomes prone to misfolding and aggregation. The pathogenesis of the disease has been associated with the dysfunction of several cellular mechanisms, inclu...
The autophagy-enhancing drug carbamazepine improves neuropathology and motor im...
Vasconcelos-Ferreira, Ana; Carmo-Silva, Sara; Codêsso, José Miguel Antunes; Silva, Patrick Joel da; Martinez, Alberto Rolim MuroMachado-Joseph disease (MJD), or spinocerebellar ataxia type 3 (SCA3), is the most common autosomal dominantly-inherited ataxia worldwide and is characterised by the accumulation of mutant ataxin-3 (mutATXN3) in different brain regions, leading to neurodegeneration. Currently, there are no available treatments able to block disease progression. In this study, we investigated whether carbamazepine (CBZ) would ac...
Cordycepin activates autophagy through AMPK phosphorylation to reduce abnormali...
Marcelo, Adriana; Brito, Filipa; Carmo-Silva, Sara; Matos, Carlos A.; Alves-Cruzeiro, Joao; Vasconcelos-Ferreira, Ana; Koppenol, RebekahMachado-Joseph disease (MJD) is a neurodegenerative disorder caused by an abnormal expansion of citosine-adenine-guanine trinucleotide repeats in the disease-causing gene. This mutation leads to an abnormal polyglutamine tract in the protein ataxin-3 (Atx3), resulting in formation of mutant Atx3 aggregates. Despite several attempts to develop a therapeutic option for MJD, currently there are no available therap...
