Visfatin reduces gap junction mediated cell-to-cell communication in proximal tubule-derived epithelial cells [PDF]

, 2013
Background/Aims: In the current study we examined if the adipocytokine, visfatin, alters connexin-mediated intercellular communication in proximal tubule-derived epithelial cells.

Proximal tubule dysfunction is associated with podocyte damage biomarkers nephrin and vascular endothelial growth factor in type 2 diabetes mellitus patients: a cross-sectional study. [PDF]

PLoS ONE, 2014
There is an ongoing debate as to whether early diabetic nephropathy in Type 2 diabetes mellitus may be attributed to the glomerulus or to the proximal tubule.

A microfluidic renal proximal tubule with active reabsorptive function

PLoS ONE, 2017
In the kidney, the renal proximal tubule (PT) reabsorbs solutes into the peritubular capillaries through active transport. Here, we replicate this reabsorptive function in vitro by engineering a microfluidic PT. The microfluidic PT architecture comprises

Proximal tubule apical endocytosis is modulated by fluid shear stress via an mTOR-dependent pathway

Molecular Biology of the Cell, 2017
Kidney proximal tubule cells cultured under shear stress become remarkably well differentiated and endocytic capacity is rapidly tuned in response to acute changes in shear stress.

The Na+/H+ Exchanger 3 in the Intestines and the Proximal Tubule of the Kidney: Localization, Physiological Function, and Key Roles in Angiotensin II-Induced Hypertension

Frontiers in Physiology, 2022
The sodium (Na+)/hydrogen (H+) exchanger 3 (NHE3) is one of the most important Na+/H+ antiporters in the small intestines of the gastrointestinal tract and the proximal tubules of the kidney.

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

, 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.

Mercapturate Pathway in the Tubulocentric Perspective of Diabetic Kidney Disease [PDF]

, 2019
BACKGROUND: The recent growing evidence that the proximal tubule underlies the early pathogenesis of diabetic kidney disease (DKD) is unveiling novel and promising perspectives.

Ontogeny of NHE8 in the rat proximal tubule [PDF]

American Journal of Physiology-Renal Physiology, 2007
Proximal tubule bicarbonate reabsorption is primarily mediated via the Na+/H+ exchanger, identified as NHE3 in adults. Previous studies have demonstrated a maturational increase in rat proximal tubule NHE3 expression, with a paucity of NHE3 expression in neonates, despite significant Na+-dependent proton secretion. Recently, a novel Na+/H+ antiporter (

A Depolarizing Leak in Sodium Bicarbonate Cotransporter NBCe1 Causes Brain Edema

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives SLC4A4 encodes electrogenic sodium bicarbonate cotransporter NBCe1, prominently expressed in kidney and brain. Recessive loss‐of‐function variants in SLC4A4 cause proximal renal tubular acidosis, no brain edema. In the brain, NBCe1 is expressed by astrocytes, where it regulates pH and mediates astrocyte volume changes.

An emerging protagonist: Sodium Glucose Co-transporters (SGLTs) as a burgeoning target for the treatment of diabetes mellitus [PDF]

, 2012
Contemporary therapies to rationalize the hyperglycaemia in type 2 diabetes mellitus (T2DM) generally involve insulin-dependent mechanisms and lose their effectiveness as pancreatic b-cell function decreases to a greater extent. The kidney emerges out as
