Erythropoietin in polycystic kidneys.
Erythropoietin (EPO) formation in kidneys of 18 patients with autosomal dominant polycystic kidney disease (ADPKD) was investigated. In 12 patients on hemodialysis and in 6 patients with preterminal renal failure serum, EPO was 29 +/- 7 and 16 +/- 1.5 mU/ml and hemoglobin concentrations were 11.0 +/- 0.6 and 12.7 +/- 1.2 g/dl, respectively. Cyst fluid from a total of 357 renal cysts was obtaine...
متن کاملGene profiling of polycystic kidneys.
BACKGROUND While the genetic basis of autosomal dominant polycystic kidney disease (ADPKD) has been clearly established, the pathogenesis of renal failure in ADPKD remains elusive. Cyst formation originates from proliferating renal tubular epithelial cells that de-differentiate. Fluid secretion with cyst expansion and reactive changes in the extracellular matrix composition combined with increa...
متن کاملAcceleration of polycystic kidney disease progression in cpk mice carrying a deletion in the homeodomain protein Cux1.
Polycystic kidney diseases (PKD) are inherited as autosomal dominant (ADPKD) or autosomal recessive (ARPKD) traits and are characterized by progressive enlargement of renal cysts. Aberrant cell proliferation is a key feature in the progression of PKD. Cux1 is a homeobox gene that is related to Drosophila cut and is the murine homolog of human CDP (CCAAT Displacement Protein). Cux1 represses the...
متن کاملIn vitro fluid secretion by epithelium from polycystic kidneys.
The size of the kidneys in patients with autosomal dominant polycystic kidney disease (ADPKD) is due in large measure to the accumulation of secreted fluid within thin-walled epithelial sacs. We measured the net transepithelial movement of liquid in response to forskolin in isolated, intact cysts excised from the surface of human ADPKD kidneys and in cultured, polarized monolayers of epithelial...
متن کاملProteolytic processing of cut homeobox 1 by neutrophil elastase in the MV4;11 myeloid leukemia cell line.
Proteolytic processing by cathepsin L generates p110 Cut homeobox 1 (CUX1) at the end of the G(1) phase, whereas an alternative transcript encodes p75 CUX1. These short CUX1 isoforms were reported to be overexpressed in cancer cells, and transgenic mice overexpressing the p75 isoform were found to develop myeloproliferative disease-like myeloid leukemias. In the present study, we report that th...
