Hypochlorite modified albumins promote cell death in the tubule interstitium in rats via mitochondrial damage in obstructive nephropathy and the protective effects of antioxidant peptides.

A major feature of the injury sustained by the kidney during obstructive nephropathy is a profound induction of apoptosis in the tubular epithelium. In this study, we explored the central roles of mitochondria and the mechanism of the protective effect of the mitochondrial targeted peptides in tubular cell apoptosis and interstitial fibrosis during obstructive nephropathy. Unilateral ureter obstruction (UUO) was performed on rats, and the animals were randomly assigned to intravenous treatment with normal saline, rat serum albumin (RSA), or HOCl-rat serum albumin (HOCl-RSA) in the presence or absence of SS-31.

Role of mitochondrial dysfunction in renal fibrosis promoted by hypochlorite-modified albumin in a remnant kidney model and protective effects of antioxidant peptide SS-31.

Oxidative stress aggravates renal fibrosis, a pathway involved in almost all forms of chronic kidney disease (CKD). However, the underlying mechanism involved in the pathogenesis of renal oxidative stress has not been completely elucidated. In this study, we explored the role and mechanism of hypochlorite-modified albumin (HOCl-alb) in mediating oxidative stress and fibrotic response in a remnant-kidney rat model.

[Effects of statins on delaying progression of chronic kidney disease: a meta-analysis].

Objective: Whether statins can slow down the progression of chronic kidney disease (CKD) remains controversial. We performed a meta-analysis to evaluate the effects of statin therapy on disease progression in adult patients with CKD who did not require dialysis therapy.

Methods: We searched the electronic databases for relevant randomized controlled trials (RCTs) published by February 2015.

Hypochlorite-Modified Albumin Upregulates ICAM-1 Expression via a MAPK-NF-κB Signaling Cascade: Protective Effects of Apocynin.

Hypochlorite-modified albumin (HOCl-alb) has been linked to endothelial dysfunction, which plays an important role in the development of hypertension, diabetes, and chronic kidney disease. However, whether HOCl-alb induces endothelial dysfunction via vascular inflammation and whether a signaling pathway is involved are unknown and have not been investigated. HOCl-alb was found to upregulate ICAM-1 expression in human umbilical vein endothelial cells (HUVECs) in a time- and dose-dependent manner.

[Preparation and spectrum of multilayer films of polyoxometalate {(Eu(PW11)2)m/PEI}].

The layer-by-layer assembly (LBL) is a new method of thin film deposition often used for oppositely charged polyelectrolytes. LBL technique has been extensively used to make multilayer films of polyions with biomolecules such as proteins, enzymes and DNA. It can also be successfully applied to the preparation of thin films of nanoparticles.
