Expression analysis in yeast model of Huntington's disease (HD)

ABSTRACT: Expressing a mutant fragment of huntingtin (Htt) in yeast produces several HD-relevant phenotypes. We used microarrays to study global change in expression induced by this mutant htt fragment. Expression was also analysed in three suppressor deletion strains expressing a toxic mutant htt fragment: bna4Δ, mbf1Δ, and ume1Δ. Yeast samples expressing either a wild-type or mutant htt fragment (Htt25Q or Htt103Q, respectively), and suppressor deletion strains expressing Htt103Q: bna4Δ, mbf1Δ, and ume1Δ.

Huntington disease (HD) is a neurodegenerative disorder caused by the expansion of a polyglutamine tract in the huntingtin (htt) protein. To uncover candidate therapeutic targets and networks involved in pathogenesis, we integrated gene expression profiling and functional genetic screening to identify genes critical for mutant htt toxicity in yeast. Using mRNA profiling, we have identified genes differentially expressed in wild-type yeast in response to mutant htt toxicity as well as in three to  ...[more]
