The 2016 Mark A. Smith Prize Winner

MSA Sumin Jung

Congratulations to our 2016 Mark Smith Award winner,  Sunmin Jung (Seoul National University), for Dual-specificity phosphatase 26 (DUSP26) stimulates Aβ42 generation by promoting amyloid precursor protein axonal transport during hypoxia
Journal of Neurochemistry (2016) J Neurochem 137(5), 770-781.
Sunmin Jung, Jihoon Nah, Jonghee Han, Seon-Guk Choi, Hyunjoo Kim, Jaesang Park, Ha-Kyung Pyo, Yong-Keun Jung. DOI: 10.1111/jnc.13597

The article makes a very interesting contribution to the study of Aβ production in Alzheimer’s brain. Hypoxia is a known risk factor for AD and stimulates Aβ generation by γ-secretase; however, the underlying mechanisms remain unclear. Under hypoxic conditions, dual-specificity phosphatase 26 (DUSP26) regulates Aβ generation through changes in subcellular localization of the γ-secretase complex and its substrate C99. DUSP26 was identified as a novel γ-secretase regulator from a genome-wide functional screen using a cDNA expression library. Additionally, DUSP26 induced c-Jun N-terminal kinase (JNK) activation for APP processing and axonal transport of C99. The results suggest that DUSP26 mediates hypoxia-induced Aβ generation through JNK activation, revealing a new regulator of γ-secretase-mediated APP processing under hypoxic conditions.

Sunmin Jung is working at Seoul National University, Department of Biological Science.

The 2015 Mark A. Smith Prize Winner

2015 Mark A Smith prizewinner Yuda Huo

Congratulations to Yuda Huo, for The deubiquitinating enzyme USP46 regulates AMPA receptor ubiquitination and trafficking
Journal of Neurochemistry (2015) J Neurochem 134(6), 1067–1080.
Yuda Huo, Natasha Khatri, Qingming Hou, James Gilbert, Guan Wang and Heng-Ye Man. DOI: 10.1111/jnc.13194
The article has broad relevance in the field of protein ubiquitination, a highly dynamic and reversible process, achieved via the balance between ubiquitination and deubiquitination. The glutamatergic AMPARs, which mediate most of the excitatory synaptic transmission in the brain, are known to be subjected to Nedd4-mediated ubiquitination; however, the deubiquitination process and the responsible deubiquitinating enzymes (DUBs) for mammalian AMPARs remain elusive. We find that AMPARs are subject to K63-type ubiquitination, and identify USP46 as the DUB for AMPARs. USP46 deubiquitinates AMPARs in vitro and in vivo. Up- or down-regulation of USP46 leads to changes in AMPAR ubiquitination, surface expression, and trafficking, as well as the strength of synaptic transmission. USP46-mediated regulation of AMPAR ubiquitination and turnover may play an important role in synaptic plasticity and brain function.

Yuda Huo has co-authored a number of relevant articles in the field in the past, using a variety of biochemical, molecular and cell biological as well as imaging methods. He is currently working at Boston University, USA under the guidance of Dr. Heng-ye Man to pursue his PhD degree in Neuroscience.

The 2013 Mark A. Smith Prize Winner

AJNC Hikita 2013

Congratulations to Takao Hikita, PhD, for Rac1-mediated indentation of resting neurons promotes the chain migration of new neurons in the rostral migratory stream of post-natal mouse brain J Neurochem 128(6), 790-797. Takao Hikita, Akihisa Ohno, Masato Sawada, Haruko Ota and Kazunobu Sawamoto. DOI: 10.1111/jnc.12518
Dr. Hikita earned his PhD in the Department of Cell Pharmacology at the Nagoya University Graduate School of Medicine in Japan. He currently holds a PostDoc position at the Max Planck Institute for Heart and Lung Research in Bad Nauheim, Germany. The winning paper sheds light on cell migration mechanisms using cutting edge techniques such as live cell imaging, and thus has broad appeal and impact in the neurochemistry and neuroscience fields.
