Abstract:
Chronic kidney disease (CKD) is an important problem throughout the world, associated with the increase of blood urea nitrogen (BUN) and serum creatinine (sCre) and with renal tubular injuries. It is crucial to elucidate the molecular mechanisms of renal injuries to identify the new therapeutics and early diagnostic methods. We focused on cell adhesion molecule-1 (CADM1) protein. CADM1, its isoform SP4, is expressed in the epithelial cells of various tissues, including renal distal tubules, localized on the lateral cell membrane, mediates cell-cell adhesion via trans-homophilic binding, and in

Abstract:
Ischemia-reperfusion- (IR-) induced kidney injury is difficult to avoid during renal transplantation and robot-assisted partial nephrectomy. Renal IR injury is characterized by tubular damage, microcirculation failure, and inflammation, which coordinately augment renal injury; however, no specific treatment is available for these conditions. Protease-activated receptor-1 (PAR-1) and its ligand, thrombin, are involved in coagulation and were shown to be associated with epithelial cell injury. Here, we hypothesized that PAR-1 exaggerated renal IR-induced tubular cell damage and microcirculation

Abstract:
Urinary tract obstruction and the subsequent development of hydronephrosis can cause kidney injuries, which results in chronic kidney disease. Although it is important to detect kidney injuries at an early stage, new biomarkers of hydronephrosis have not been identified. In this study, we examined whether vanin-1 could be a potential biomarker for hydronephrosis. Male Sprague-Dawley rats were subjected to unilateral ureteral obstruction (UUO). On day 7 after UUO, when the histopathological renal tubular injuries became obvious, the vanin-1 level in the renal pelvic urine was significantly high

Abstract:
Preterm birth interrupts the development and maturation of the kidneys during the critical growth period. The kidneys can also exhibit structural defects and functional impairment due to hyperoxia, as demonstrated by various animal studies. Furthermore, hyperoxia during nephrogenesis impairs renal tubular development and induces glomerular and tubular injuries, which manifest as renal corpuscle enlargement, renal tubular necrosis, interstitial inflammation, and kidney fibrosis. Preterm birth along with hyperoxia exposure induces a pathological predisposition to chronic kidney disease. Hyperoxi

Abstract:
Most chronic kidney injuries inevitably progress to irreversible renal fibrosis. Tubular epithelial-to-mesenchymal transition (EMT) is recognized to play pivotal roles in the process of renal fibrosis. However, a comprehensive understanding of the pathogenesis of renal scar formation and progression remains an urgent task for renal researchers. The endogenously produced microRNAs (miRNAs), proved to play important roles in gene regulation, probably regulate most genes involved in EMT.

Abstract:
The convoluted (CPT) and straight (SPT) portions of the renal proximal tubule are susceptible to injury by a wide variety of chemical agents. These agents often affect the CPT or SPT selectively by proposed mechanisms usually attributed to tubular concentration, blood flow delivery patterns and tubuloglomerular feedback responses within the intact kidney. The innate cellular responses to chemical exposures remain virtually unexplored. Hence, the basic goal of this research was to develop an in vitro system that was conducive to examining the innate cellular differences in susceptibility betwee

It is well known that a variety of toxicants can cause damage to the renal proximal tubule. However, the early pathogenesis of these deleterious interactions between a toxicant and this region of the nephron remain poorly understood. Thus, the purpose of this research was to attempt to answer three interrelated questions. First, what are the earliest changes in kidney function and structure after administration of tubule toxicants in vivo? Secondly, how do these structural/functional alterations change over time? Finally, are certain indicators of renal "dysfunction" more sensitive then other

Abstract:
Three major hypotheses attempt to explain progressive kidney disease following diverse diseases and injuries. To varying degrees they can explain the observed risk factors for progression and the ability of interventions to lower risk. The hyperfiltration hypothesis argues that progression is due to stress on residual nephrons leading to injury and damage to remaining glomeruli. The toxicity of proteinuria hypothesis proposes that serum proteins or bound substances are toxic to tubular or tubulointerstitial cells. This sets up cycles of damage which lead to tubulointerstitial scarring. The pod

Abstract:
Despite improvements in short-term renal allograft survival, long-term survival has not appreciably changed. Excepting death with a functioning graft, most late graft loss results from chronic allograft dysfunction. Immune and non-immune-mediated injuries contribute to graft dysfunction over time, ultimately leading to a non-specific and irreversible histological end-point of fibrosis, tubular atrophy, and glomerulosclerosis. Screening and early identification of pathology is crucial to allow timely intervention in order to prevent permanent nephron damage and graft loss. This chapter outlines

Abstract It is a well established observation from both human and animal studies of renal disease, that once a degree of renal damage has occurred then the progression of kidney failure is inexorable, even if the original injurious process has resolved [1]. Such observations have led to the hypothesis that following renal damage of any aetiology a maladaptive response occurs in the remaining nephrons which results in their eventual destruction by a common pathogenic mechanism. In support of this, the histological appearance of the kidney in end-stage renal disease is similar whatever the initi

Abstract Alterations in endothelial cell function occur not only as part of new vessel formation, but also wound healing. Small injuries to the endothelial cell monolayer heal by migration of adjacent endothelial cells into the wound; after they reattach to the underlying matrix, they then reenter the cell cycle and divide to replace the denuded cells. In angiogenesis, the first step under most circumstances is dissolution of the underlying matrix, brought about by release of proteases (e.g., collagenases and plasminogen activator) from the stimulated endothelial cells themselves or from cells
