Exploratory experiment designed to discover new patterns targeting TFEB in cell models expressing misfolded proteins. Primary outcome: clearance of misfolded protein aggregates
This experiment tested the functional significance of trehalose-induced autophagy by examining its effects on the clearance of disease-causing misfolded proteins in motoneuron disease models. The study used filter retardation assays and immunofluorescence to measure the degradation of aggregate-prone proteins. TFEB silencing experiments were performed to confirm that the pro-degradative activity of trehalose on misfolded proteins was dependent on TFEB function. The researchers also tested trehalase-resistant analogs to confirm the mechanism was independent of trehalose metabolism.
