increment. it is categorized based on genetic aberrations. some of these genetic disorders can determine minimal residual diseases (mrd) and prognosis of aml patients. wilms tumor (wt1) over expression is found in aml patients. the aim of this study was to determine the frequency of wt1 over expression in aml pediatric cases in north -east of iran. materials and methods: this retrospective stud...

Background: Acute myeloid leukemia (AML) is one of myeloid malignancies which the risk increases with age increment. It is categorized based on genetic aberrations. Some of these genetic disorders can determine minimal residual diseases (MRD) and prognosis of AML patients. Wilms tumor (WT1) over expression is found in AML patients. The aim of this study was to determine the frequency of WT1 ove...

BACKGROUND Wilms' tumor is an embryonal neoplasm of the kidney that accounts for approximately 6 % of all childhood tumors. The chemokine CXCL12 (C-X-C chemokine ligand 12) and its ligand CXCR4 (C-X-C chemokine receptor type 4) are involved in the development of several organs, including the kidney, and are also associated with tumor growth and metastasis. FOXP3 (forkhead transcription factor 3...

objectives this study aimed at reviewing the current literature on the diagnosis, staging, and different treatment strategies for wilms’ tumor with either ureteral or intravascular extension. evidence acquisition in this article, we reviewed the current literature about staging, diagnosis, and management strategies for wt, through a randomized clinical trial, which focused on this matter. the m...

background: neuroblastoma is the most common tumor in infancy and wilms’ tumor is the most common malignant tumor of kidney in childhood. both the tumors are usually within the differential diagnosis of each other. this study compares the clinical manifestations, sex and age distribution of childhood wilms’ tumor and neuroblastoma at one of tehran children hospitals. materials and methods: the ...

Anaplastic histology and metastasis are each associated with higher relapse and mortality rates in Wilms tumor patients. However, not all anaplastic tumors relapse and some nonanaplastic tumors relapse unexpectedly. To identify more accurate early prognostic indicators, we analyzed expression of 4,900 cancer-related genes in 26 primary Wilms tumors. This analysis revealed that expression of a s...

background: the wilms tumor 1 (wt1) gene is originally defined as a tumor suppressor gene and a transcription factor that overexpressed in leukemic cells. it is highly expressed in more than 80% of acute myeloid leukemia (aml) patients, both in bone marrow (bm) and in peripheral blood (pb), and it is used as a powerful and independent marker of minimal residual disease (mrd);we have determined ...

Wilms' tumor (WT) is associated with loss of heterozygosity at chromosome 11p13, the site of the Wilms' tumor suppressor gene, WT1. Although the preferential loss of maternal alleles suggested that differential allelic expression of WT1 might occur, this has not been evident in normal fetal tissues or WTs. In this study, we show that the WT1 antisense regulatory region is differentially methyla...
