| Research Abstract |
HRD1 promotes degradation of unfolded proteins in the endoplasmic reticulum as a ubiquitin ligase. In the present study, we suggest the possible involvement of oxidative stresses in the decrease of HRD1 protein, which promotes degradation of amyloid precursor protein (APP), in the brain of Alzheimer's disease (AD) patient. Furthermore, we evaluated whether HRD1 knockout mice exhibited the phenotypes of AD. In addition, we found another ubiquitin ligase, which is involved in the APP protein metabolism.
