Long-Term Outcome of Zero-Ischemia Partial Nephrectomy for the Treatment of Multifocal Renal Cell Carcinoma in Renal Transplant Allograft: A Case Report.

Exp Clin Transplant 2019 Jan;17(Suppl 1):145-147

From the Department of Urology and Kidney Transplantation, Shahid Labbafinejad Medical Center, Shahid Beheshti University of Medical Sciences, Tehran, Iran.

Multifocal synchronous renal cell carcinoma in the functioning allograft is a rare disease; there is no consensus regarding its treatment, and few cases have been reported. In isolated masses, some authorities advocate graft nephrectomy, and some recommend partial nephrectomy. To our knowledge, we describe the first experience of nephron-sparing surgery in multifocal synchronous renal cell carcinoma in an allograft with its long-term outcome. Read More

Whole-Exome Sequencing Enables a Precision Medicine Approach for Kidney Transplant Recipients.

J Am Soc Nephrol 2019 Feb 17;30(2):201-215. Epub 2019 Jan 17.

Division of Nephrology,

Background: Whole-exome sequencing (WES) finds a CKD-related mutation in approximately 20% of patients presenting with CKD before 25 years of age. Although provision of a molecular diagnosis could have important implications for clinical management, evidence is lacking on the diagnostic yield and clinical utility of WES for pediatric renal transplant recipients.

Methods: To determine the diagnostic yield of WES in pediatric kidney transplant recipients, we recruited 104 patients who had received a transplant at Boston Children's Hospital from 2007 through 2017, performed WES, and analyzed results for likely deleterious variants in approximately 400 genes known to cause CKD.

Autosomal dominant polycystic kidney disease: Disrupted pathways and potential therapeutic interventions.

J Cell Physiol 2019 Jan 15. Epub 2019 Jan 15.

Department of Stem Cells and Developmental Biology, Cell Science Research Center, Royan Institute for Stem Cell Biology and Technology, ACECR, Tehran, Iran.

Autosomal dominant polycystic kidney disease (ADPKD) is a monogenic inherited renal cystic disease that occurs in different races worldwide. It is characterized by the development of a multitude of renal cysts, which leads to massive enlargement of the kidney and often to renal failure in adulthood. ADPKD is caused by a mutation in PKD1 or PKD2 genes encoding the proteins polycystin-1 and polycystin-2, respectively. Read More

Increased water intake reduces long-term renal and cardiovascular disease progression in experimental polycystic kidney disease.

PLoS One 2019 2;14(1):e0209186. Epub 2019 Jan 2.

Centre for Transplant and Renal Research, Westmead Institute for Medical Research, The University of Sydney, Sydney, NSW, Australia.

Polycystic kidney disease (PKD) is the most common inherited cause of kidney failure and currently has limited treatment options. Increasing water intake reduces renal cyst growth in the pck rat (a genetic ortholog of autosomal recessive PKD) but it is not clear if this beneficial effect is present in other models of PKD. In this study, we tested the hypothesis that high water intake (HWI) reduces the progression of cystic renal disease in Lewis polycystic kidney (LPK) rats (a genetic ortholog of human nephronophthisis-9).

Pediatric cystic diseases of the kidney.

J Ultrasound 2019 Jan 1. Epub 2019 Jan 1.

Radiology Department, Federico II University, Naples, Italy.

Pediatric renal cystic diseases include a variety of hereditary or non-hereditary conditions. Numerous classifications exist and new data are continuously published. Ultrasound is the primary technique for evaluating kidneys in children: conventional and high-resolution US allows a detailed visualization of renal parenchyma and of number, size and location of the cysts, hence representing the most important diagnostic imaging technique for the first diagnosis and follow-up of these young patients.

Kidney cysts can manifest as focal disease (simple and complex kidney cysts), affect a whole kidney (eg, multicystic dysplastic kidney or cystic dysplasia), or manifest as bilateral cystic disease (eg, autosomal recessive polycystic kidney disease [ARPKD] or autosomal dominant polycystic kidney disease [ADPKD]). In children, as opposed to adults, a larger proportion of kidney cysts are due to genetic diseases (eg, HNF1B nephropathy, various ciliopathies, and tuberous sclerosis complex), and fewer patients have simple cysts or acquired cystic kidney disease. The purpose of this consensus statement is to provide clinical guidance on standardization of imaging tests to evaluate kidney cysts in children. Read More

Urinary Tract Cytology.

Vet Clin North Am Small Anim Pract 2019 Mar 24;49(2):247-260. Epub 2018 Dec 24.

Department of Pathology and Population Medicine, Midwestern University College of Veterinary Medicine, 5715 West Utopia Road, Glendale, AZ 85308, USA.

Cytologic evaluation of the urinary tract can be diagnostically rewarding in cases of renomegaly or when discrete kidney or bladder masses are identified. Cytology can often help to distinguish between cystic, inflammatory, and neoplastic disorders. Various types of cystic and benign urinary tract lesions, diseases associated with urinary tract inflammation, and the cytologic differences between primary and metastatic neoplasms of the kidney and bladder are described.

Characterization of purinergic receptor expression in ARPKD cystic epithelia.

Purinergic Signal 2018 12 11;14(4):485-497. Epub 2018 Nov 11.

Department of Physiology, Medical College of Wisconsin, 8701 Watertown Plank Road, Milwaukee, WI, 53226, USA.

Polycystic kidney diseases (PKDs) are a group of inherited nephropathies marked by formation of fluid-filled cysts along the nephron. Growing evidence suggests that in the kidney formation of cysts and alteration of cystic electrolyte transport are associated with purinergic signaling. PCK/CrljCrl-Pkhd1pck/CRL (PCK) rat, an established model of autosomal recessive polycystic kidney disease (ARPKD), was used here to test this hypothesis. Read More

The expression of somatostatin receptor 2 decreases during cyst growth in mice with polycystic kidney disease.

Exp Biol Med (Maywood) 2018 Sep 27;243(13):1092-1098. Epub 2018 Sep 27.

1 Department of Human Genetics, Leiden University Medical Center, Leiden 2300 RC, The Netherlands.

Impact Statement: Somatostatin (SST) analogs have been shown to halt cyst growth and progression of autosomal dominant polycystic kidney disease by several clinical trials. However, two studies suggest that the effect of the SST analog octreotide on kidney growth during the first year of treatment is reduced in the subsequent follow-ups and the kidney enlargement resumes. This biphasic change in kidney growth during octreotide treatment may be partially explained by alterations in SSTR2 expression. Read More

Congenital malformations of the seminal vesicle are uncommon, and most of them are cystic malformations. If an insult occurs during the first trimester of gestation, the embryogenesis of the kidney, ureter, seminal vesicle, and vas deferens could be altered. The mutual embryological origins of the seminal vesicle and ureteral bud from the mesonephric (Wolffian) duct result in association between ipsilateral renal agenesis and seminal vesical cysts.

Precision toxicology shows that troxerutin alleviates ochratoxin A-induced renal lipotoxicity.

FASEB J 2019 Feb 24;33(2):2212-2227. Epub 2018 Sep 24.

Beijing Advanced Innovation Center for Food Nutrition and Human Health, College of Food Science and Nutritional Engineering, China Agricultural University, Beijing, China.

Lipotoxicity is the most common cause of severe kidney disease, with few treatment options available today. Precision toxicology can improve detection of subtle intracellular changes in response to exogenous substrates; thus, it facilitates in-depth research on bioactive molecules that may interfere with the onset of certain diseases. In the current study, troxerutin significantly relieved nephrotoxicity, increased endurance, and improved systemic energy metabolism and renal inflammation in OTA-induced nephrotic mice. Read More

Ultrasound and color Doppler applications in chronic kidney disease.

J Nephrol 2018 Dec 6;31(6):863-879. Epub 2018 Sep 6.

Sant'Anna School of Advanced Studies, Department of Internal Medicine, University of Pisa, Pisa, Italy.

Chronic kidney disease (CKD) includes all clinical features and complications during the progression of various kidney conditions towards end-stage renal disease (ESRD). These conditions include immune and inflammatory disease such as: primary and hepatitis C virus (HCV)-related glomerulonephritis; infectious disease such as pyelonephritis with or without reflux and tuberculosis; vascular disease such as chronic ischemic nephropathy; hereditary and congenital disease such as polycystic disease and congenital cystic dysplasia; metabolic disease including diabetes and hyperuricemia; and systemic disease (collagen disease, vasculitis, myeloma). During the progression of CKD, ultrasound imaging and color Doppler imaging (US-CDI) can differentiate the etiology of the renal damage in only 50-70% of cases. Read More

New insights into the role of HNF-1β in kidney (patho)physiology.

Pediatr Nephrol 2018 Jul 1. Epub 2018 Jul 1.

Department of Internal Medicine, University of Texas Southwestern Medical Center, Dallas, TX, USA.

Hepatocyte nuclear factor-1β (HNF-1β) is an essential transcription factor that regulates the development and function of epithelia in the kidney, liver, pancreas, and genitourinary tract. Humans who carry HNF1B mutations develop heterogeneous renal abnormalities, including multicystic dysplastic kidneys, glomerulocystic kidney disease, renal agenesis, renal hypoplasia, and renal interstitial fibrosis. In the embryonic kidney, HNF-1β is required for ureteric bud branching, initiation of nephrogenesis, and nephron segmentation. Read More

Autosomal dominant polycystic kidney disease (ADPKD) is associated with progressive enlargement of cysts, leading to a decline in function and renal failure that cannot be prevented by current treatments. Mutations in and , encoding the polycystin 1 and 2 proteins, induce growth-related pathways, including heat shock proteins, as occurs in some cancers, raising the prospect that pharmacological interventions that target these pathways might alleviate or prevent ADPKD. Here, we demonstrate a role for VX-809, a corrector of cystic fibrosis transmembrane conductance regulator (CFTR), conventionally used to manage cystic fibrosis in reducing renal cyst growth.

Acquired Cystic Disease-associated Renal Cell Carcinoma (ACD-RCC): A Multiinstitutional Study of 40 Cases With Clinical Follow-up.

Am J Surg Pathol 2018 Sep;42(9):1156-1165

Robert J Tomsich Pathology and Laboratory Medicine Institute, Cleveland Clinic.

The incidence of renal cell carcinoma (RCC) is known to be higher in patients with end-stage renal disease, including those with acquired cystic kidney disease due to dialysis. Acquired cystic disease (ACD)-associated RCC was recently incorporated into the 2016 WHO Classification of Tumors of the Urinary System and Male Genital Tract as a distinct entity and is reportedly the most common RCC arising in end-stage renal disease. In this study, we sought to further describe clinicopathologic findings in a large series of ACD-RCC, emphasizing histologic features, immunophenotype, clinical outcome, and patterns of disease spread.

Long noncoding RNA is dysregulated in autosomal dominant polycystic kidney disease and regulates mTOR signaling.

J Biol Chem 2018 06 1;293(24):9388-9398. Epub 2018 May 1.

From the Department of Medicine and.

Autosomal dominant polycystic kidney disease (ADPKD) is a debilitating disease that is characterized by the accumulation of numerous fluid-filled cysts in the kidney. ADPKD is primarily caused by mutations in two genes, and Long noncoding RNAs (lncRNA), defined by a length >200 nucleotides and absence of a long ORF, have recently emerged as epigenetic regulators of development and disease; however, their involvement in PKD has not been explored previously. Here, we performed deep RNA-Seq to identify lncRNAs that are dysregulated in two orthologous mouse models of ADPKD (kidney-specific and mutant mice). Read More

Are Pax proteins potential therapeutic targets in kidney disease and cancer?

Kidney Int 2018 08 21;94(2):259-267. Epub 2018 Apr 21.

Department of Pathology, University of Michigan, Ann Arbor, Michigan, USA. Electronic address:

Pax genes encode developmental regulators that are expressed in a variety of tissues and control critical events in morphogenesis. In the kidney, Pax2 and Pax8 are expressed in embryonic development and in specific renal diseases associated with aberrant epithelial cell proliferation. Prior genetic and cell biological studies suggest that reducing the activity of Pax proteins in renal cancer or in polycystic kidney disease can slow the progression of these conditions. Read More

Macedonia Academy of Science and Arts, Skopje, Republic of Macedonia.

Rare renal diseases (RRD) are an important category of rare disease (RD) as they can do great damage to the patients, families and society. The patient may undergo years even decades of numerous investigations including invasive procedures and yet not have definitive and precise diagnose and therefore, no opportunity for appropriate treatment. The great progress in molecular genetic techniques characterized many Mendelian diseases on molecular level. Read More

Eukaryotic cilia are assembled by intraflagellar transport (IFT) where large protein complexes called IFT particles move ciliary components from the cell body to the cilium. Defects in most IFT particle proteins disrupt ciliary assembly and cause mid gestational lethality in the mouse. IFT25 and IFT27 are unusual components of IFT-B in that they are not required for ciliary assembly and mutant mice survive to term. Read More

Inhibition of Hedgehog signaling suppresses proliferation and microcyst formation of human Autosomal Dominant Polycystic Kidney Disease cells.

Sci Rep 2018 Mar 21;8(1):4985. Epub 2018 Mar 21.

Department of Anatomy and Cell Biology, University of Kansas Medical Center, Kansas City, KS, USA.

Autosomal Dominant Polycystic Kidney Disease (ADPKD) is caused by mutation of PKD1 or PKD2, which encode polycystin 1 and 2, respectively. The polycystins localize to primary cilia and the functional loss of the polycystin complex leads to the formation and progressive growth of fluid-filled cysts in the kidney. The pathogenesis of ADPKD is complex and molecular mechanisms connecting ciliary dysfunction to renal cystogenesis are unclear. Read More

Transepithelial Fluid and Salt Re-Absorption Regulated by cGK2 Signals.

Int J Mol Sci 2018 Mar 16;19(3). Epub 2018 Mar 16.

Institute of Metabolic Disease Research and Drug Development, China Medical University, Shenyang 110122, China.

Transepithelial fluid and salt re-absorption in epithelial tissues play an important role in fluid and salt homeostasis. In absorptive epithelium, fluid and salt flux is controlled by machinery mainly composed of epithelial sodium channels (ENaC), cystic fibrosis transmembrane conductance regulator (CFTR), Na⁺/H⁺ exchanger (NHE), aquaporin, and sodium potassium adenosine triphosphatase (Na⁺/K⁺-ATPase). Dysregulation of fluid and salt transport across epithelium contributes to the pathogenesis of many diseases, such as pulmonary edema and cystic fibrosis. Read More

The epithelial sodium channel (ENaC) mediates sodium absorption in lung, kidney, and colon epithelia. Channels in the ENaC/degenerin family possess an extracellular region that senses physicochemical changes in the extracellular milieu and allosterically regulates the channel opening. Proteolytic cleavage activates the ENaC opening, by the removal of specific segments in the finger domains of the α- and γ ENaC-subunits. Read More
