SIRT2-and NRF2-Targeting Thiazole-Containing Compound with Therapeutic Activity in Huntington's Disease Models

There are currently no disease-modifying therapies for the neurodegenerative disorder Huntington's disease (HD). This study identified novel thiazole-containing inhibitors of the deacetylase sirtuin-2 (SIRT2) with neuroprotective activity in ex vivo brain ...

Synchrotron Infrared Microspectroscopy Detecting the Evolution of Huntington's Disease Neuropathology and Suggesting Unique Correlates of Dysfunction in White versus Gray Brain Matter

László Forró, Sylvia Jeney, Heike Runne, Markus Bonda

Huntington's disease (HD), caused by a mutation of the corresponding gene encoding the protein huntingtin (htt), is characterized by progressive deterioration of cognitive and motor functions, paralleled by extensive loss of striatal neurons. At the cellul ...

Developmental expression of Synaptotagmin isoforms in single calyx of Held-generating neurons

Ralf Schneggenburger, Olexiy Kochubey, Yunyun Han, Heather Mary Elizabeth Murray, Heike Runne, Le Xiao

The large glutamatergic calyx of Held synapse in the auditory brainstem has become a powerful model for studying transmitter release mechanisms, but the molecular bases of presynaptic function at this synapse are not well known. Here, we have used single-c ...

SIRT2 inhibition achieves neuroprotection by decreasing sterol biosynthesis

Ozgün Gökce, Heike Runne

Huntington's disease (HD), an incurable neurodegenerative disorder, has a complex pathogenesis including protein aggregation and the dysregulation of neuronal transcription and metabolism. Here, we demonstrate that inhibition of sirtuin 2 (SIRT2) achieves ...

Diminished activity-dependent brain-derived neurotrophic factor expression underlies cortical neuron microcircuit hypoconnectivity resulting from exposure to mutant huntingtin fragments

Henry Markram, Michele Giugliano, Elena Katsyuba, Ozgün Gökce, Heike Runne, Luca Gambazzi

Although previous studies of Huntington's disease (HD) have addressed many potential mechanisms of striatal neuron dysfunction and death, it is also known, based on clinical findings, that cortical function is dramatically disrupted in HD. With respect to ...

Short-term striatal gene expression responses to brain-derived neurotrophic factor are dependent on MEK and ERK activation

Ozgün Gökce, Heike Runne

BACKGROUND: Brain-derived neurotrophic factor (BDNF) is believed to be an important regulator of striatal neuron survival, differentiation, and plasticity. Moreover, reduction of BDNF delivery to the striatum has been implicated in the pathophysiology of H ...

Transcriptional dysregulation in Huntington's disease

Heike Runne

Huntington's disease (HD) is a progressive neurodegenerative disorder with autosomal dominant inheritance. It is caused by a singular mutation in exon 1 of the HD gene encoding an abnormal polyglutamine (polyQ) expansion in the N-terminal region of the hun ...

Dysregulation of gene expression in primary neuron models of Huntington's disease shows that polyglutamine-related effects on the striatal transcriptome may not be dependent on brain circuitry

Patrick Aebischer, Valérie Gafner, Ozgün Gökce, Nicole Déglon, Heike Runne, Diana Zala

Gene expression changes are a hallmark of the neuropathology of Huntington's disease (HD), but the exact molecular mechanisms of this effect remain uncertain. Here, we report that in vitro models of disease comprised of primary striatal neurons expressing ...

Analysis of potential transcriptomic biomarkers for Huntington's disease in peripheral blood

Mauro Delorenzi, Heike Runne

Highly quantitative biomarkers of neurodegenerative disease remain an important need in the urgent quest for disease-modifying therapies. For Huntington's disease (HD), a genetic test is available (trait marker), but necessary state markers are still in de ...
