1 Constitutive overexpression of the Hsp70 molecular chaperone is capable of suppressing polyglutamine neurodegeneration. polyglutamine Heat-shock-protein-70Ab Drosophila melanogaster
2 We further showed that cellular heat shock response remained intact in aged flies, indicating the decline of Hsp70 levels observed in polyglutamine-expressing flies is not due to normal ageing. polyglutamine Heat-shock-protein-70Ab Drosophila melanogaster
3 In contrast to the well-documented polyglutamine suppression caused by constitutive Hsp70 overexpression, no suppression of degeneration was observed when inducible copies of hsp70 transgenes were instead coexpressed. polyglutamine Heat-shock-protein-70Ab Drosophila melanogaster
4 This supports a transcriptional dysregulation of endogenous hsp70 gene induction in polyglutamine flies. polyglutamine Heat-shock-protein-70Ab Drosophila melanogaster
