Nedd4-2 has been proposed to play a critical role in regulating epithelial Na+ channel (ENaC) activity. Biochemical and overexpression experiments suggest that Nedd4-2 binds to the PY motifs of ENaC subunits via its WW domains, ubiquitinates them, and decreases their expression on the apical membrane. Phosphorylation of Nedd4-2 (for example by Sgk1) may(More)
Effective improvement in sorghum crop development necessitates a genomics-based approach to identify functional genes and QTLs. Sequenced in 2009, a comprehensive annotation of the sorghum genome and the development of functional genomics resources is key to enable the discovery and deployment of regulatory and metabolic genes and gene networks for crop(More)
The case of a 12-year-old with a hybrid CFH/CFHL1 gene and atypical hemolytic uremic syndrome (aHUS) that had previously developed native kidney and then renal allograft loss is reported. This case illustrates the relatively common occurrence of renal loss from the late presentation of aHUS. Also presented is a protocol for the pre-emptive use of eculizumab(More)

The entity of focal segmental glomerulosclerosis (FSGS), oddly, includes several distinct changes involving glomeruli that need not be focal, segmental, or even sclerotic. It is fitting to rethink our nosological approach to FSGS, which has focused on descriptive morphological entities. Rather, we should consider them as 'podocytopathies' - diseases with an(More)
Acute rejection is a major cause of kidney allograft dysfunction. It is important to distinguish between cellular and antibody-mediated rejection to guide the treatment strategy. The management of acute antibody-mediated rejection includes aggressive therapy with plasmapheresis and intravenous immunoglobulin. C4d staining of peritubular capillaries has(More)
Cigarette smoking may have harmful effects on both native and transplant kidneys. Although a causal relationship was not shown, nodular glomerulosclerosis was reported in association with long-term cigarette smoking. We report a 48-year-old woman with a long-term history of smoking who underwent cadaveric renal transplantation. A renal biopsy to assess a(More)
ABO-incompatible (ABOI) living donor kidney transplantation has become a well-accepted practice with standard protocols using perioperative antibody-depleting therapies to lower blood group titers to an acceptable threshold for transplantation. However, a subset of patients will experience accelerated antibody-mediated rejection (AMR) after ABOI kidney(More)
Focal segmental glomerulosclerosis (FSGS) is the cause of renal failure in more than 10% of pediatric patients undergoing renal transplantation. Recurrent FSGS is a major cause of pediatric allograft failure, with the risk increasing for patients undergoing retransplantation. Standard therapy for recurrent posttransplantation FSGS includes the use of(More)
BACKGROUND/AIMS We examined the correlations between renal biopsy findings in Wegener's granulomatosis and renal function at baseline and 1 year in 22 patients who presented between 1988 and 1999. METHODS Renal histology was independently reviewed by 2 pathologists who were masked to the clinical data. The primary outcome was the relationship of the(More)
