Axial differences in endocytosis along the kidney proximal tubule [PDF]

open access: yesAmerican Journal of Physiology-Renal Physiology, 2019
The proximal tubule (PT) reabsorbs filtered proteins via receptor-mediated endocytosis to prevent energetically inefficient wasting in the urine. Recent intravital imaging studies have suggested that protein reabsorption occurs in early (S1) segments, which have a very high capacity.

Biochemical heterogeneity of arginine metabolism along kidney proximal tubules

open access: yesKidney International, 1996
By using an in vitro single tubule micromethod of high specificity, in four different species of mammals it has been observed that (a) arginine synthesis from citrulline (arginine synthase activity, E.C. 6.3.4.5 and E.C. 4.3.2.1) is restricted to the early portions of proximal convoluted tubules, whereas (b) urea production from arginine (arginase ...

Changes in renal WT-1 expression preceding hypertension development [PDF]

open access: yes, 2016
Background: Hypertension is a public health problem with mostly unknown causes, and where strong hereditary genetic alterations have not been fully elucidated. However, the use of experimental models has provided valuable information.

Adaptive changes in GFR, tubular morphology, and transport in subtotal nephrectomized kidneys: modeling and analysis [PDF]

open access: yes, 2017
Removal of renal mass stimulates anatomical and functional adaptations in the surviving nephrons, including elevations in single-nephron glomerular filtration rate (SNGFR) and tubular hypertrophy. A goal of this study is to assess the extent to which the

Intratubular, Intracellular, and Mitochondrial Angiotensin II/AT1 (AT1a) Receptor/NHE3 Signaling Plays a Critical Role in Angiotensin II-Induced Hypertension and Kidney Injury

open access: yesFrontiers in Physiology, 2021
Hypertension is well recognized to be the most important risk factor for cardiovascular diseases, stroke, and end-stage kidney failure. A quarter of the world’s adult populations and 46% of the US adults develop hypertension and currently require ...

Fyn Phosphorylates Transglutaminase 2 (Tgm2) and Modulates Autophagy and p53 Expression in the Development of Diabetic Kidney Disease

open access: yesCells, 2023
Autophagy is involved in the development of diabetic kidney disease (DKD), the leading cause of end-stage renal disease. The Fyn tyrosine kinase (Fyn) suppresses autophagy in the muscle. However, its role in kidney autophagic processes is unclear.

Proximal tubular deletion of superoxide dismutase-2 reveals disparate effects on kidney function in diabetes

open access: yesRedox Biology
There is a large body of evidence implicating mitochondrial reactive oxygen species (ROS) overproduction and oxidative stress in the development of diabetic kidney disease and the deficiency of mitochondrial antioxidant systems in the kidney, such as ...

Quantitative morphology of renal cortical structures during compensatory hypertrophy [PDF]

open access: yes, 1998
The compensatory hypertrophy in different renal cortical structures was studied in rats 10 and 21 days after unilateral nephrectomy (UNX). Quantitative morphological/stereological analysis revealed significant increases in total renal cortical volume ...
