Uncovering the mystery of how oxidative stress, the culprit of aging and neurodegenerative diseases, accumulates and operates in the motor system

Peng JJ, Lin SH, Liu YT, Lin HC, Li TN, Yao CK
Increased oxidative stress is considered to be one of the key factors leading to aging and neurodegenerative diseases, but it is not clear why oxidative stress can accumulate in the nervous system and affect the functioning of the nervous system.

Sharp Tools Make Good Work: The Early Success of ASCEM

Chen CY, Chang YC, Lin BL, Lin KF, Huang CH, Hsieh DL, Ko TP, Tsai MD
Dr. Ming-Daw Tsai, Director of Academia Sinica Cryo-EM Center (ASCEM) and Distinguished Research Fellow of Institute of Biological Chemistry, collaborates with Dr. Chin-Yu Chen, an assistant professor from Department of Life Science National Central University, in using the state of the art technology, cryo-electron microscopy (cryo-EM), to uncover the structural bases of pH effect and cofactor bispecificity of ketol-acid reductoisomerase from archaea Sulfolobus solfataricus. The result is published in the Journal of the American Chemical Society on April 17 and featured on the Journal cover.

Rice can be drowned! Although rice is a semi-aquatic plant, the seedlings will die if they are submerged completely under water and oxygen is depleted. Recent climate change has transformed once-in-a-lifetime typhoon or heavy rainfall into a frequent occurrence, which greatly reduced rice production in Taiwan.

The C-terminal D/E-rich domain of MBD3 is a putative Z-DNA mimic that competes for Zα DNA-binding activity

Lee CH, Shih YP, Ho MR, Wang AH*
Academician Andrew H.-J. Wang and his team at the Institute of Biological Chemistry have recently found that the C-terminal D/E-rich domain of MBD3 was able to associate with the Z-DNA binding domain (Zα) of ADAR1. The D/E-rich domain of MBD3 may act as a DNA mimic to compete with Z-DNA for binding to Zα. The interplay of MBD3 and ADAR1 may participate in regulating the local DNA conformational transition between B-DNA and Z-DNA and thereby results in alterations in gene expression.
