BACKGROUND Wilms' tumor is an emberyonal tumor arising from remnants of immature renal tissue. Her2/neu is an onco-protein which mediates cellular proliferation, differentiation and survival. METHODS In the current study, we analyzed Her2/neu expression in 40 Wilms' tumors. The clinico-demographic data of 40 patients with Wilms' tumor were retrieved. Immunohistochemical staining for HER2/neu ...

Wilms' tumor or nephroblastoma is believed to arise from embryonic nephrogenic rests of multipotent cells that fail to terminally differentiate into epithelium and continue to proliferate. The WT1 tumor suppressor gene, a transcription factor controlling the mesenchymal-epithelial transition in renal development, is mutated in 10% to 15% of Wilms' tumors. This potentially explains the disordere...

Insulin-like growth factor-II (IGF-II) is thought to play a critical role in the development of embryonic tumors such as Wilms' tumor. However, despite highly elevated IGF-II mRNA levels in tumors, IGF-II is not elevated in the serum of patients with Wilms' tumors. Recently high molecular weight forms of IGF-II ('big'- or pro-IGF-II) have been found to be produced by some tumors. In order to pr...

Extrarenal Wilms' tumor of the ovary is a very rare tumor likely derived from embryonic mesonephros. We present the first reported case of a teratoid extrarenal Wilms' tumor of the ovary with a short review of the existing literature. In the case, a 26-year-old woman presented with back pain and was found to have a dermoid cyst; three years later, she presented again, now pregnant, with severe ...

We have previously demonstrated an increased DNA copy number and expression of IGF1R to be associated with poor outcome in Wilms tumors. We have now tested whether inhibiting this receptor may be a useful therapeutic strategy by using a panel of Wilms tumor cell lines. Both genetic and pharmacological targeting resulted in inhibition of downstream signaling through PI3 and MAP kinases, G(1) cel...
