AI Article Synopsis
Article Abstract
There are at least eight aquaporins (AQPs) expressed in the kidney. Including AQP1 expressed in proximal tubules, thin descending limb of Henle and vasa recta; AQP2, AQP3, AQP4, AQP5, and AQP6 expressed in collecting ducts; AQP7 expressed in proximal tubules; AQP8 expressed in proximal tubules and collecting ducts; and AQP11 expressed in the endoplasmic reticulum of proximal tubular epithelial cells. Over years, researchers have constructed different AQP knockout mice and explored the effect of AQP knockout on kidney function. Thus, the roles of AQPs in renal physiology are revealed, providing very useful information for addressing fundamental questions about transepithelial water transport and the mechanism of near isoosmolar fluid reabsorption. This chapter introduces the localization and function of AQPs in the kidney and their roles in different kidney diseases to reveal the prospects of AQPs in further basic and clinical studies.

The PKM2 activator TEPP-46 suppresses cellular senescence in hydrogen peroxide-induced proximal tubular cells and kidney fibrosis in CD-1 mice.

Aim/introduction: Senescence is a key driver of age-related kidney dysfunction, including diabetic kidney disease. Oxidative stress activates cellular senescence, induces abnormal glycolysis, and is associated with pyruvate kinase muscle isoform 2 (PKM2) dysfunction; however, the mechanisms linking PK activation to cellular senescence have not been elucidated. We hypothesized that PKM2 activation by TEPP-46 could suppress oxidative stress-induced renal tubular cell injury and cellular senescence.

Introduction: Diabetic nephropathy (DN) is a common diabetes-related complication with unclear underlying pathological mechanisms. Although recent studies have linked glycolysis to various pathological states, its role in DN remains largely underexplored.
Methods: In this study, the expression patterns of glycolysis-related genes (GRGs) were first analyzed using the GSE30122, GSE30528, and GSE96804 datasets, followed by an evaluation of the immune landscape in DN.

Background And Objective: Mitochondria are crucial to the function of renal tubular cells, and their dynamic perturbation in many aspects is an important mechanism of diabetic kidney disease (DKD). Single-nucleus RNA sequencing (snRNA-seq) technology is a high-throughput sequencing analysis technique for RNA at the level of a single cell nucleus. Here, our DKD mouse kidney single-cell RNA sequencing conveys a more comprehensive mitochondrial profile, which helps us further understand the therapeutic response of this unique organelle family to drugs.

SLC17A3 localized to the apical membrane of the renal proximal tubules has been implicated in the urinary excretion of drugs and endogenous/exogenous metabolites transported into the tubules by OAT1 and OAT3. Because SLC17A3 mediates the facilitated diffusion of organic anions, which requires a sensitive and rapid assay, no system has been established to evaluate its transport activity in mammalian cells. In this study, we demonstrated that the exposure of cells expressing click beetle luciferase (bLuc) and SLC17A3 to D-luciferin produces marked bioluminescence, which enables the evaluation of SLC17A3 function.

WBP1L is a broadly expressed transmembrane adaptor protein involved in regulating hematopoietic stem cell function and T cell development. It interacts with NEDD4-family E3 ubiquitin ligases and regulates important chemokine receptor CXCR4. Using tandem affinity purification coupled with mass spectrometry, we identified novel WBP1L interactions with the IFNγ receptor and the Cullin-RING ubiquitin ligases CRL1.
