Protease-activated receptor-2 (PAR2) is a G protein-coupled receptor abundantly expressed in the kidney. The aim of this study was to profile inflammatory gene and protein expression induced by PAR2 activation in human kidney tubular epithelial cells (HTEC). A novel PAR2 antagonist, GB88, was used to confirm agonist specificity. Intracellular Ca(2+) (iCa(2+)) mobilization, confocal microscopy, gene expression profiling, qRTPCR, and protein expression were used to characterize PAR2 activation. PAR2 induced a pronounced increase in iCa(2+) concentration that was blocked by the PAR2 antagonist. Treatment with SLIGKV-NH2 at the apical or basolateral cell surface for 5 h induced expression of a range of inflammatory genes by greater than fourfold, including IL-1β, TRAF1, IL-6, and MMP-1, as assessed by cDNA microarray and qRTPCR analysis. Using antibody arrays, GM-CSF, ICAM-1, TNF-α, MMP-1, and MMP-10 were among the induced proteins secreted. Cytokine-specific ELISAs identified three- to sixfold increases

1. The present study has determined the kinetics of the uptake of L-3,4-dihydroxyphenylalanine (L-DOPA) and 3-O-methyl-L-DOPA (3-OMDOPA) in rat renal tubules and examined the effect of 3-OMDOPA on the inward transport of L-DOPA and on its conversion into dopamine in kidney homogenates. 2. The accumulation of both L-DOPA and 3-OMDOPA in renal tubules was found to occur through non-saturable and saturable mechanisms. The kinetics of the saturable component of L-DOPA and 3-OMDOPA uptake in renal tubules were as follows: L-DOPA, Vmax = 11.1 nmol mg-1 protein h-1 and Km = 216 microM (n = 6); 3-OMDOPA, Vmax = 8.1 nmol mg-1 protein h-1 and Km = 231 microM (n = 5). The diffusion constant of the non-saturable component for the accumulation of L-DOPA and 3-OMDOPA was 0.0010 and 0.0014 mumol-1, respectively. 3. 3-OMDOPA (100 to 2000 microM) was found to produce a concentration-dependent decrease (29% to 81% reduction) of the saturable component of the tubular uptake of L-DOPA; the Ki value of 3-OMDOPA for
Proteinuria is the most important predictor of outcome in glomerulonephritis and experimental data suggest that the tubular cell response to proteinuria is an important determinant of progressive fibrosis in the kidney. However, it is unclear whether proteinuria is a marker of disease severity or has a direct effect on tubular cells in the kidneys of patients with glomerulonephritis. Accordingly we studied an in vitro model of proteinuria, and identified 231 albumin-regulated genes differentially expressed by primary human kidney tubular epithelial cells exposed to albumin. We translated these findings to human disease by studying mRNA levels of these genes in the tubulo-interstitial compartment of kidney biopsies from patients with IgA nephropathy using microarrays. Biopsies from patients with IgAN (n=25) could be distinguished from those of control subjects (n=6) based solely upon the expression of these 231 albumin-regulated genes. The expression of an 11-transcript subset related to the ...

exchanger or the BSC-1 and BSC-2 isoforms of the Na+/K+/2Cl−cotransporter, could also be involved in RTC apoptosis, by impeding intracellular volume expansion. However, prominent functions for these proteins in proximal RTC apoptosis are unlikely, since none are abundantly expressed in the proximal tubule (1,15, 18).. In addition to cell shrinkage, RTC NHE1 degradation was also associated with intracellular acidification (16). The data are in agreement with studies in leukocyte cell lines, which demonstrate that apoptosis is preceded by decreased pHi (16,27, 36). Importantly, NHE1 stimulation prevented intracellular acidification and abrogated apoptosis (16, 36), indicating NHE1 activation opposes apoptosis. Rich et al. (40) demonstrated that human leukemia cells exhibit a significantly higher pHi compared with normal leukocyte lineage cells. Moreover, decreased pHi was associated with increased apoptosis, which was exacerbated by exposure to the NHE1 inhibitor HMA. Barrière et al. (2) ...

Guinea pigs injected with heterologous renal basement membranes (RBM) and complete Freunds adjuvant (FA) develop a new renal cortical tubular disease and form antibodies that react with renal tubular basement membrane (TBM) (1-3). We now document the characteristics and immunopathology of this renal tubular disease and the presence of anti-TBM antibodies in the serum and along the cortical TBM. Finally, we demonstrate a positive correlation between the incidence of severe tubular disease and large amounts of anti-cortical TBM autoantibodies.. Materials and Methods. RBM, rich in TBM, were prepared from frozen New Zealand White rabbit kidneys3 by a modification of Krakower and Greenspons method (4). Briefly, rabbit cortex was buttered through a 100-mesh metal screen. The screenings were washed by centrifugation in saline to remove free cells. By repeated shaking and washing of the residue, glomeruli settled faster than tubules. Supernatants rich in tubules were examined microscopically (4, ...
Experiments were performed to evaluate the influence of the distal tubular feedback mechanism on glomerular function in the dog. Single nephron glomerular filtration rate (SNGFR) and stop-flow pressure (SFP) were measured from early segments of proximal tubules during alterations in distal perfusion rate (via a late proximal puncture site) and perfusate composition. Perfusion rate (PR) was varied from 16 to 68 nl/min with a microperfusion pump. The intermediate segment of the nephron was blocked with a solid wax cast, thus preventing retrograde influences of the microperfusion procedure. During perfusion with an ultrafiltrate of plasma and an artificial tubular fluid solution (ATF), SNGFR decreased from 63 ± 2.6 (SE) nl/min at a PR of 16 nl/min to 20 ± 2.4 nl/min at a PR of 63 ± 2.6 nl/min. At a PR of 16 nl/min, SFP was 48 ± 1.3 mmHg with ultrafiltrate and ATF. Increases in PR to 68 nl/min led to a reduction in SFP to 26 ± 1.5 mmHg. SFP was also measured during changes in PR with various ...

Unilateral ureteral obstruction (UUO) is characterized by progressive renal atrophy, renal interstitial fibrosis, an increase in renal transforming growth factor-β (TGF-β), and renal tubular apoptosis. The present study was undertaken to determine the effect of a monoclonal antibody to TGF-β (1D11) in UUO. Methods. Mechanical stretch was applied to tubular epithelial cells (NRK-52E) by a computer-assisted system.

N2 - Increases in sodium delivery to the distal nephron reduce glomerular filtration rate (GFR) via tubuloglomerular feedback (TGF). Central volume expansion and pharmacological concentrations of atrial natriuretic factor (ANF) are known to attenuate this response. To test the hypothesis that whole kidney TGF is attenuated by pathophysiological concentrations of ANF, hypertonic saline was given intrarenally in five dogs receiving an intravenous infusion of synthetic ANF at 20 ng·kg-1·min-1. To examine whole kidney TGF responses in heart failure, six additional dogs with acute congestive heart failure induced by rapid ventricular pacing also received intrarenal hypertonic saline. Seven sham-paced dogs served as controls. An isolated increase in circulating ANF from 26 ± 3 to 342 ± 23 pg/ml abolished the whole kidney GFR response to ...
We recently reported the existence of certain renal tubular cells that participate in kidney regeneration. These cells were identified as LRTC and were shown to be a potential source of regenerating cells after renal ischemia (23). Here, we isolated LRTC from adult kidney tubules by separating a Hoechstlow population by FACS. These cells could be distinguished by expression of marker genes and by functional assays. We found that (1) LRTC proliferate with epithelial marker expression in response to certain growth factors but, unlike non-LRTC, have a unique in vitro proliferation and differentiation response to MM cell line-derived soluble factors; (2) the growth and differentiation pattern of LRTC is affected by ECM; (3) LRTC form cyst-like or tubule-like structures in collagen gels; and (4) LRTC are integrated into several types of renal cells when transplanted into embryonic kidney.. During tubular regeneration after injury, the expression of various growth factors is altered (3) and there are ...

SLK activity and appearance are increased during kidney advancement and recovery from renal ischemia-reperfusion damage. understood poorly. The Ste20-like kinase SLK is certainly an organization V GCK portrayed in kidney tubular epithelial cells also to a lesser level in glomerular visceral epithelial cells (GECs; podocytes). Previously we confirmed that appearance and activity of SLK had been elevated in rat fetal kidneys weighed against adult control kidneys which renal ischemia-reperfusion damage enhanced SLK appearance and activity in adult rat kidneys.7 Thus SLK is a renal epithelial proteins kinase whose expression and activity are increased during advancement and recovery from acute renal failure where injured tubular epithelial cells may regenerate by recapitulating developmental procedures.8 Moreover expression of SLK in mature and developing podocytes suggests a possible role in glomerulogenesis or glomerular injury. The regulatory and functional areas of SLK have obtained considerable ...

AU - Lee, Vivian S.. PY - 2016/12/1. Y1 - 2016/12/1. N2 - MRI can provide excellent detail of renal structure and function. Recently, novel MR contrast mechanisms and imaging tools have been developed to evaluate microscopic kidney structures including the tubules and glomeruli. Quantitative MRI can assess local tubular function and is able to determine the concentrating mechanism of the kidney noninvasively in real time. Measuring single nephron function is now a near possibility. In parallel to advancing imaging techniques for kidney microstructure is a need to carefully understand the relationship between the local source of MRI contrast and the underlying physiological change. The development of these imaging markers can impact the accurate diagnosis and treatment of kidney disease. This study ...
We have examined the timing of specification of the pronephric tubules and duct in Xenopus laevis by explanting the presumptive pronephric rudiments into blastula ectodermal wraps. We have established I-he time point of specification using the monoclonal antibody markers 3G8 and 4A6 which recognize antigens in pronephric tubule and duct, respectively. We show that, by experimental analysis in explants, kidney tubules are specified by stage 12.5 in the pronephric anlagen whereas pronephric duct is specified later between stages 13 and 14. Furthermore we show that signals involved in tubulogenesis of the pronephric tubules are normally received between stage 12.5 and 13. These experiments unambiguously pinpoint the timing of pronephros specification analyzed by explant experimentation to a developmental stage prior to that demonstrated for urodele amphibia, and provide an essential biological backdrop to a search for the molecular nature of pronephric inducers.

The work carried out was multifaceted, dealing with the many factors concerned in acute and chronic injury to renal tubules. In view of the fact that most tubular lesions are the consequence of vascular impairment, many of the studies involved an examination of the behavior of arteries, arterioles and glomeruli in the face of different stimuli. The juxtaglomerular apparatus is intimately concerned in the regulation of blood flow and experiments were carried out to shed light on this structure. The factors concerned in the stimulus for hyperplasia of the juxtaglomerular apparatus were studied to test the validity of the notion that the tonicity of the filtrate acting on the macula densa is of importance.

Tubulointerstitial and glomerular accumulations of immune cells, such as macrophages and T cells, are a prominent feature of a variety of nephritis (6, 31, 32, 33). The C-C family of chemokines is major mononuclear cell chemoattractants and may be central to the recruitment of these cells. As LPS is involved in the onset or progression of acute and chronic renal diseases (2, 3, 4, 5), C-C chemokines produced by renal cells after LPS exposure (44, 45, 46) may play a predominant role in the pathogenesis. LPS initiates multiple intracellular signaling events, including the activation of NF-κB, AP-1, and three distinct MAPKs: p38 MAPK, ERK, and JNK (7). Recently, it has been documented that LPS-induced MCP-1 gene expression in rat tubular epithelial cells is NF-κB dependent (46). In our studies performed by using various inhibitors, the LPS-mediated MCP-1 mRNA increase was dependent on NF-κB activation, but not on the three MAPK signaling pathways. In contrast, much less is known about the ...

The mechanism of sodium retention and its location in kidney tubules may vary with time in nephrotic syndrome (NS). We studied the mechanisms of sodium retention in transgenic POD-ATTAC mice, which display an inducible podocyte-specific apoptosis. At day 2 after the induction of NS, the increased abundance of NHE3 and phosphorylated NCC in nephrotic mice compared with controls suggest that early sodium retention occurs mainly in the proximal and distal tubules. At day 3, the abundance of NHE3 normalized, phosphorylated NCC levels decreased, and cleavage and apical localization of γ-ENaC increased in nephrotic mice. These findings indicate that sodium retention shifted from the proximal and distal tubules to the collecting system. Increased cleavage and apical localization of γ-ENaC persisted at day 5 in nephrotic mice when hypovolemia resolved and steady-state was reached. Sodium retention and γ-ENaC cleavage were independent of the increased plasma levels of aldosterone. Nephrotic mice displayed

Ureteral obstruction leads to renal damage via a bimodal process, with tubular apoptosis occurring as an early event followed by the release of cytokines and chemokines from the injured tubular cell, resulting in inflammatory reaction and interstitial fibrosis. Thus it has been suggested that inhibition of tubular apoptosis may protect against subsequent inflammatory response and interstitial fibrosis (5). Treatments targeting various mediators of apoptosis and inflammation, such as neutralizing antibodies of TGF-β1 and angiotensin-converting enzyme (ACE) inhibitors, have reduced early apoptosis and late fibrosis. Oxidative stress resulting from mechanical stretch and ischemia also play an important role in tubular apoptosis, and antioxidants may be useful therapeutic agents for UUO. However, previous attempts to limit tissue damage by targeting ROS with antioxidants have met with limited success (13, 18, 22, 25, 31). In this study, we provide a proof of concept that using a ...

Ly-6 is a multigene family of murine polymorphic cell membrane proteins that are glycosydlphosphatidylinositol anchored, widely expressed on lymphoid tissue, and homologous to the recently described human CD59. An unexpected feature of Ly-6 is its high level of expression in the kidney. This renal expression and its interferon (IFN)-gamma inducibility in murine strains expressing different Ly-6 haplotypes were studied with monoclonal antibodies and cDNA probes that recognize Ly-6A/E and Ly-6C. Ly-6 expression was much more extensive in the kidney than in other parenchymal organs. Ly-6A.1/E.2 was extensively expressed on vascular endothelium and on tubular epithelium, particularly in the distal nephron. Pattern of expression differed between strains expressing A and E alleles. Ly-6C was not detected by monoclonal antibodies but was detected by oligonucleotide-specific probes. Treatment with recombinant IFN-gamma or IFN-inducing agents increased Ly-6 expression markedly, particularly on the luminal aspect
The term tubulointerstitial is used to broadly refer to kidney diseases that involve structures in the kidney outside the glomerulus. These diseases generally involve tubules and/or the interstitium of the kidney and spare the glomeruli, as shown in the image below.
At one end of each nephron, in the cortex of the kidney, is a cup shaped structure called the (Bowmans or renal) capsule. It surrounds a tuft of capillaries called the glomerulus that carries high-pressure blood. Together the glomerulus and capsule act as a blood-filtering device . The holes in the filter allow most of the contents of the blood through except the red and white cells and large protein molecules. The fluid flowing from the capsule into the rest of the kidney tubule is therefore very similar to blood plasma and contains many useful substances like water, glucose, salt and amino acids. It also contains waste products like urea ...

... Background. Tissue damage at the time of organ transplantation has a negative impact on the subsequent success of the procedure, both in the immediate and longer term. Hypothermia is the principal element used to prolong organ viability ex vivo, but paradoxically also induces cellular edema through inhibition of energy-dependent adenosine triphosphatases (ATPases). This induces an electrolyte imbalance that leads to fluid influx and cell swelling. It is important, therefore, that improvements are made in the preservation of ischemic organs to reduce this injury. Methods. This study has applied a novel in vitro system to model cold and warm ischemic-induced renal tubule swelling that characterizes tissue damage in ischemia/reperfusion injury. Biochemical blockade of ATPases in this system using strophanthidin modeled the effects of energy depletion and induced cell swelling. By measuring such tubule swelling ...
