Alport syndrome is a hereditary glomerulopathy with proteinuria and nephritis caused by defects in genes encoding type IV collagen in the glomerular basement membrane. All male and most female patients develop end-stage renal disease. Effective treatment to stop or decelerate the progression of proteinuria and nephritis is still under investigation. Here we(More)
Alport syndrome (AS) is one of the most common types of inherited nephritis caused by mutation in one of the glomerular basement membrane components. AS is characterized by proteinuria at early stage of the disease and glomerular hyperplastic phenotype and renal fibrosis at late stage. Here, we show that global deficiency of tumor suppressor p53(More)
Sirtuin 1 (SIRT1), an NAD(+)-dependent histone deacetylase, plays crucial roles in various biological processes including longevity, stress response, and cell survival. Endoplasmic reticulum (ER) stress is caused by dysfunction of ER homeostasis and exacerbates various diseases including diabetes, fatty liver, and chronic obstructive pulmonary disease.(More)
Exogenous low-intensity electrical stimulation has been used for treatment of various intractable diseases despite the dearth of information on the molecular underpinnings of its effects. Our work and that of others have demonstrated that applied electrical stimulation at physiological strength or mild electrical stimulation (MES) activates the PI3K-Akt(More)
Alport syndrome (AS) is a hereditary kidney disease caused by mutation of type IV collagen. Loss of collagen network induces collapse of glomerular basement membrane (GBM) structure. The previous studies showed that upregulation of some tyrosine kinase receptors signaling accompanied GBM disorder in AS mouse model. EGFR signaling is one of the well-known(More)
