Recent reports have shown that the endoplasmic reticulum (ER) stress is relevant to the pathogenesis of Alzheimer disease. Following the amyloid cascade hypothesis, we therefore attempted to investigate the effects of ER stress on amyloid-beta peptide (Abeta) generation. In this study, we found that ER stress altered the localization of amyloid precursor(More)
Tauopathy is a pathological condition with an abnormal intracellular accumulation of tau protein in neurons and glias, which is a feature of Alzheimer's disease (AD) as well as frontotemporal lobar degenerations (FTLD). Recent reports showed that tauopathy occupies an important position for pathological process of dementia generally. Previously, we reported(More)
We recently demonstrated that endoplasmic reticulum (ER) stress induces sigma-1 receptor (Sig-1R) expression through the PERK pathway, which is one of the cell's responses to ER stress. In addition, it has been demonstrated that induction of Sig-1R can repress cell death signaling. Fluvoxamine (Flv) is a selective serotonin reuptake inhibitor (SSRI) with a(More)
Due to chemotherapy, the majority of breast cancer patients survive, but frequently complain of chemotherapy-associated cognitive impairment. This phenomenon is termed "chemobrain" or "chemofog" in the literature. However, its mechanisms are unclear. The objective of this study was to investigate the mechanisms of paclitaxel (Px)-induced neurotoxicity, with(More)
