We have reported recently that inhibition of protein phosphatase (PP)-2A and PP-1 by calyculin A, a specific inhibitor of PP-2A and PP-1, induced Alzheimer-like hyperphosphorylation of tau and spatial memory retention impairment. In this study, we tested the in vivo effects of melatonin on these Alzheimer-like changes. We found that administration of(More)
Aluminum (Al) is the most abundant metal in the earth’s crust. Al accumulates in erythrocyte and causes toxicity on erythrocyte membrane. The dysfunction of erythrocyte membrane is a potential risk to hypertension. The high Al content in plasma was associated with hypertension. To investigate the effect of AlCl3 on blood pressure and the function of(More)
Aluminum promotes osteoblast (OB) apoptosis. Apoptosis is induced by the disordered calcium homeostasis. Therefore, to investigate the relationship between Al-induced OB apoptosis and calcium homeostasis, calvarium OBs from neonatal rats (3–4 days) were cultured and exposed to 0.048-mg/mL Al3+ or 0.048-mg/mL Al3+ combined with 5 μM BAPTA-AM (OBs were(More)
The retromer complex is an important component of the endosomal protein sorting machinery and mediates protein cargoes from endosomes to the trans-Golgi network (TGN) by retrograde pathway or to the cell surface through recycling pathway. Studies show that retromer and its receptors can make amyloid precursor protein (APP)/β-site APP-cleaving enzyme 1(More)
