Induction Of The Heat Shock Response To Protect Against Polyglutamine Diseases And The Role Of Protein Sumoylation In Laminopathies And Alzheimer's Disease, Yu-Qian Zhang
University of Kentucky Doctoral Dissertations
Heat shock proteins function as molecular chaperones which help protein folding and prevent protein aggregation. My study shows that celastrol, a pharmacological compound capable of up-regulating the levels of heat shock proteins, inhibits cell death and protein aggregation caused by expanded polyglutamine containing protein, and the protective effects of celastrol are dependent on heat shock factor 1. These results suggest the potential of celastrol as a therapeutic agent in the treatment of polyglutamine diseases.
Sumoylation is a protein modification which plays diverse roles in regulating the target proteins. My study shows that lamin A is a target of protein sumoylation, …
