Comparison of the Effects of Mesenchymal Stem Cells with Their Extracellular Vesicles on the Treatment of Kidney Damage Induced by Chronic Renal Artery Stenosis.

Background: Chronic renal artery stenosis is considered one of the most common causes of renovascular hypertension (RH). Chronic hypoxia can lead to irreversible damage to renal tissue and to a progressive deterioration of renal function. We have previously shown that bone marrow-derived mesenchymal stem cells (BMSCs) improved renal parenchyma and function in a model of RH (2 kidneys, 1 clip model (2K-1C) in rats.

miR-26a modulates HGF and STAT3 effects on the kidney repair process in a glycerol-induced AKI model in rats.

Acute kidney injury is mostly reversible, and hepatocyte growth factor (HGF) has a relevant role in the tissue repair. MicroRNA (miR)-26a is an endogenous modulator of HGF. The role of miR-26a in the kidney repair process was evaluated in Wistar rats submitted to an acute kidney injury model of rhabdomyolysis induced by glycerol (6 mL/kg).

Intracrine action of angiotensin II in mesangial cells: subcellular distribution of angiotensin II receptor subtypes AT and AT.

Biological effects of angiotensin II (AngII) such as regulation of AngII target genes may be triggered by interaction of AngII with intracellular AngII receptor types 1 and 2 (AT and AT), defined as intracrine response. The aim of this study was to examine the presence of AT and AT receptors in nuclear membrane of human mesangial cells (HMCs) and evaluate the possible biological effects mediated by intracellular AT through an intracrine mechanism. Subcellular distribution of AT and AT was evaluated by immunofluorescence and by western blot in isolated nuclear extract.

Cardiovascular and Renal Effects of Birdseed Associated with Aerobic Exercise in Rats.

Introduction: Phalaris canariensis L. (Pc), known as birdseed, is rich in tryptophan. The aqueous extract of Pc (AEPc) treatment reduced systolic blood pressure (SBP) in spontaneously hypertensive rats (SHR) via mechanisms mediated by the tryptophan metabolizing enzyme indoleamine 2,3-dioxygenase (IDO).
