Autophagy in Huntington disease and huntingtin in autophagy

DDO Martin, S Ladha, DE Ehrnhoefer… - Trends in neurosciences, 2015 - cell.com
Autophagy is an important biological process that is essential for the removal of damaged
organelles and toxic or aggregated proteins by delivering them to the lysosome for degradation…

Small changes, big impact: posttranslational modifications and function of huntingtin in Huntington disease

DE Ehrnhoefer, L Sutton, MR Hayden - The Neuroscientist, 2011 - journals.sagepub.com
… The SENP family of enzymes is responsible for the de-SUMOylation of htt. (B) Alternatively,
lysines 6, 9, and 15 of htt can be ubiquitinated by E3 ligases, including E2-25K, which directs …

Caspase-6 and neurodegeneration

RK Graham, DE Ehrnhoefer, MR Hayden - Trends in neurosciences, 2011 - cell.com
Caspases are cysteine-aspartic proteases that post-translationally modify their substrates
through cleavage at specific sites, which causes either substrate inactivation or a gain of …

EGCG redirects amyloidogenic polypeptides into unstructured, off-pathway oligomers

DE Ehrnhoefer, J Bieschke, A Boeddrich… - Nature structural & …, 2008 - nature.com
The accumulation of β-sheet–rich amyloid fibrils or aggregates is a complex, multistep process
that is associated with cellular toxicity in a number of human protein misfolding disorders, …

EGCG remodels mature α-synuclein and amyloid-β fibrils and reduces cellular toxicity

…, J Russ, RP Friedrich, DE Ehrnhoefer… - Proceedings of the …, 2010 - National Acad Sciences
Protein misfolding and formation of β-sheet-rich amyloid fibrils or aggregates is related to
cellular toxicity and decay in various human disorders including Alzheimer’s and Parkinson’s …

Balance between synaptic versus extrasynaptic NMDA receptor activity influences inclusions and neurotoxicity of mutant huntingtin

…, M Talantova, D Yao, P Xia, DE Ehrnhoefer… - Nature medicine, 2009 - nature.com
Huntington's disease is caused by an expanded CAG repeat in the gene encoding huntingtin
(HTT), resulting in loss of striatal and cortical neurons. Given that the gene product is …

Green tea (−)-epigallocatechin-gallate modulates early events in huntingtin misfolding and reduces toxicity in Huntington's disease models

DE Ehrnhoefer, M Duennwald… - Human molecular …, 2006 - academic.oup.com
Huntington's disease (HD) is a progressive neurodegenerative disorder for which only
symptomatic treatments of limited effectiveness are available. Preventing early misfolding steps …

Full-length huntingtin levels modulate body weight by influencing insulin-like growth factor 1 expression

…, Y Xie, NH Skotte, DE Ehrnhoefer… - Human molecular …, 2010 - academic.oup.com
Levels of full-length huntingtin (FL htt) influence organ and body weight, independent of
polyglutamine length. The growth hormone-insulin like growth factor-1 (GH-IGF-1) axis is well …

Mouse models of Huntington disease: variations on a theme

DE Ehrnhoefer, SL Butland… - Disease models & …, 2009 - journals.biologists.com
An accepted prerequisite for clinical trials of a compound in humans is the successful alleviation
of the disease in animal models. For some diseases, however, successful translation of …

HACE1 reduces oxidative stress and mutant Huntingtin toxicity by promoting the NRF2 response

…, AL Southwell, DE Ehrnhoefer… - Proceedings of the …, 2014 - National Acad Sciences
… We therefore tested whether HACE1 promotes NRF2 protein synthesis, as NRF2 nuclear
localization under oxidative stress is dependent on de novo NRF2 synthesis (22). To compare …
