Loss of chromosome 16 from renal epithelial cells in humans.

Observation of Inclusion Bodies in Renal Epithelial Cells of Experimelltally Infected Horses with African Horse-Sickness Virus

Loss of the polycystic kidney disease (PKD1) region of chromosome 16p13 in renal cyst cells supports a loss-of-function model for cyst pathogenesis.

It is not known whether mutations in the PKD1 gene cause autosomal dominant polycystic kidney disease (PKD) by an activating (gain-of-function) or an inactivating (loss-of-function) model. We analyzed DNA from cyst epithelial cells for loss of heterozygosity (LOH) in the PKD1 region of chromosome 16p13 using microsatellite markers. 29 cysts from four patients were studied. Five cysts from three...

Allelic loss at chromosome 3p characterizes clear cell phenotype of renal cell carcinoma.

Incidence of the loss of heterozygosity on chromosome 3p was evaluated using 7 polymorphic probes in 35 Japanese patients with sporadic renal cell carcinoma (RCC). Overall frequency of the loss of heterozygosity on 3p was 53%, representing 16 of 30 informative cases. Examination of the relationship between histopathological phenotypes of RCC and incidence of the 3p loss revealed that the loss o...

Specific loss of chromosomes 1, 2, 6, 10, 13, 17, and 21 in chromophobe renal cell carcinomas revealed by comparative genomic hybridization.

We analyzed 19 chromophobe renal cell carcinomas by means of comparative genomic hybridization. Two tumors revealed no numerical abnormalities. In the remaining 17 cases we found loss of entire chromosomes with underrepresentation of chromosome 1 occurring in all 17 cases; loss of chromosomes 2, 10, and 13 in 16 cases; loss of chromosomes 6 and 21 in 15 tumors; and loss of chromosome 17 in 13 c...

Renal Cyst Cells Supports a Loss-of-Function Model for Cyst Pathogenesis
