To elucidate the pathogenic mechanisms in Huntington's disease (HD) elicited by expression of full-length human mutant huntingtin (fl-mhtt), a bacterial artificial chromosome (BAC)-mediated transgenic mouse model (BACHD) was developed expressing fl-mhtt with 97 glutamine repeats under the control of endogenous htt regulatory machinery on the BAC. BACHD mice(More)
We used affinity-purification mass spectrometry to identify 747 candidate proteins that are complexed with Huntingtin (Htt) in distinct brain regions and ages in Huntington's disease (HD) and wild-type mouse brains. To gain a systems-level view of the Htt interactome, we applied Weighted Correlation Network Analysis to the entire proteomic data set to(More)
Huntington's disease (HD) is a fatal dominantly inherited neurodegenerative disorder caused by a CAG repeat expansion leading to an elongated polyglutamine stretch in huntingtin. Mutant huntingtin (mHTT) is ubiquitously expressed in all cells but elicits selective cortical and striatal neurodegeneration in HD. The mechanistic basis for such selective(More)
We identified a Cu-accumulating structure with a dynamic role in intracellular Cu homeostasis. During Zn limitation, Chlamydomonas reinhardtii hyperaccumulates Cu, a process dependent on the nutritional Cu sensor CRR1, but it is functionally Cu deficient. Visualization of intracellular Cu revealed major Cu accumulation sites coincident with electron-dense(More)
Huntington's disease (HD) is a fatal dominantly inherited neurodegenerative disorder caused by a CAG repeat expansion leading to an elongated polyglutamine stretch in Huntingtin 1. Mutant Huntingtin (mHTT) is ubiquitously expressed but elicits selective cortical and striatal neurodegeneration in HD 2. The mechanistic basis for such selective neuronal(More)
