1. Nephron-sparing surgery for treatment of reninoma: a rare renin secreting tumor causing secondary hypertension
Main findings A 25-year-old hypertensive female patient was referred to our institution. Initial workup exams demonstrated a 2.8 cm cortical lower pole tumor in the right kidney. She underwent laparoscopic partial nephrectomy without complications. Histopathologic examination revealed a rare juxtaglomerular cell tumor known as reninoma. After surgery, she r

2. "Fatores clínicos e biológicos para recidivas em tumores de Wilms localizados" / Clinical and biological factors for relapse in localized wilms tumor
Apesar do excelente prognóstico dos tumores de Wilms (TW) localizados (estádios I e II) e de histologia favorável (HF), 10% deles recidivam. Em 122 pacientes com TW com essas características, diagnosticados de 1976 e 2001, analisamos alguns fatores clínicos, como a idade por ocasião do diagnóstico e peso do tumor, em todos os pacientes; fatores bioló

3. Infrequent involvement of c-fos in avian leukosis virus-induced nephroblastoma.
To determine whether c-fos is involved in avian leukosis virus-induced nephroblastoma, 28 tumors from chickens were analyzed for novel fos fragments. DNA from 1 of 16 clonal outgrowths (in chicken 6561) contained novel fos-related EcoRI and KpnI fragments which hybridized to both v-fos and viral probes. Oncogenicity tests using filtered 6561 tumor cell homog

4. The noncoding and surface envelope coding sequences of myeloblastosis-associated virus are respectively responsible for nephroblastoma development and renal hyperplasia.
The use of chimeric viruses allowed us to establish that myeloblastosis-associated virus long terminal repeat sequences are necessary and sufficient for induction of nephroblastoma in chickens and that the blastemal hyperplasia induced by env SU is not a prerequisite for tumor development but rather constitutes a predisposing stage.

6. Pathology of chickens infected with avian nephoblastoma virus MAV-2(N).
A neophroblastoma-inducing myeloblastosis-associated virus, MAV-2(N), derived from avian myeloblastosis virus was characterized with respect to biochemical composition and avian pathogenesis. Purified fibroblast-grown virus contained the same size 35S ribonucleic acid and the same relative amounts of viral polypeptides as another myeloblastosis-associated vi

8. Induction of nephroblastoma by myeloblastosis-associated virus type 1: state of proviral DNAs in tumor cells.
Myeloblastosis-associated virus type 1 (MAV1) derived from a molecular clone of infectious proviral DNA (B. Perbal, J. S. Lipsick, J. Svoboda, R. F. Silva, and M. A. Baluda, J. Virol. 56:240-244, 1985) was shown to specifically induce nephroblastoma in chickens and therefore belongs to the MAV-N class. We show that nephroblastomas are polyclonal tumors conta

9. Immunocytochemical localisation of renin in nephroblastoma.
An antibody to pure human renin and an immunoperoxidase technique were used to stain immunoreactive renin in nephroblastomas. In an unselected series of surgically removed nephroblastomas immunoreactive renin was found in 10 of 19 tumours (53%). Tissue obtained at necropsy from 12 cases of disseminated nephroblastoma was also studied, and immunoreactive reni

10. Transfection of Chicken Embryo Cells with DNA Extracted from Avian Virus-Producing Neoplastic Cells
DNA isolated from avian virus-producing leukemic myeloblasts induced the production of viruses, but not morphological transformation, in cultivated chicken fibroblasts. The recovered virus had the same biological characteristics as the original avian myeloblastosis virus (AMV) and produced myeloblastosis and nephroblastomas when injected into chickens. Neutr

11. Wilms' tumour and a de novo (1;7) translocation in a child with bilateral radial aplasia
The case of a child with nephroblastoma, bilateral radial aplasia, and a de novo (1;7) translocation is reported.

12. Differential expression of novH and CTGF in human glioma cell lines
Aims—(1) To investigate the expression in human derived glioblastoma cell lines of two structurally related genes, novH (nephroblastoma overexpressed gene) and CTGF (connective tissue growth factor), which encode putative insulin-like growth factor binding proteins of a novel type. (2) To investigate whether the same transcription factors regulate CTGF and
