WT1 (Wilms' tumor gene 1): biology and cancer immunotherapy.
Wilms' tumor gene WT1 encodes a transcription factor and plays an important role in cell growth and differentiation. The WT1 gene is highly expressed in leukemia and various types of solid tumors, whereas WT1 is a tumor marker convenient for the detection of minimal residual disease of leukemia. The WT1 gene was originally defined as a tumor suppressor gene, but we proposed that it was, on the ...
متن کاملWilms' tumor suppressor gene (WT1) is expressed in primary breast tumors despite tumor-specific promoter methylation.
We analyzed Wilms' tumor suppressor 1 (WT1) expression and its regulation by promoter methylation in a panel of normal breast epithelial samples and primary carcinomas. Contrary to previous reports, WT1 protein was strongly expressed in primary carcinomas (27 of 31 tumors) but not in normal breast epithelium (1 of 20 samples). Additionally, the WT1 promoter was methylated in 6 of 19 (32%) prima...
متن کاملOverexpression of the Wilms' tumor gene WT1 in esophageal cancer.
BACKGROUND The Wilms' tumor gene WT1 is overexpressed in various kinds of solid cancers. However, it remains unclear whether WT1 is expressed in esophageal squamous cell carcinoma. MATERIALS AND METHODS Expression of the WT1 gene was examined by real-time RT-PCR in 12 esophageal squamous cell carcinoma (ESCC) and by immunohistochemistry in 9 of these 12 and another 29. RESULTS Real-time RT-...
متن کاملMutations in the Wilms' tumor gene WT1 in leukemias.
The tissue-specific Wilms' tumor gene WT1 is expressed in a range of acute leukemias and hematopoietic cell lines. Using single-strand conformational polymorphism analysis, we have found mutations in the WT1 gene in 4 of 36 acute leukemias. WT1 mutations are found in 15% of cases of acute myeloid leukemia, in which they are associated with a poor response to chemotherapy. The mutations comprise...
متن کاملWT1 splicing alterations in Wilms' tumors.
Hereditary and sporadic forms of tumors are generally related to germ-line and somatic mutations of the same tumor suppressor gene. Unexpectedly, in Wilms' tumor, somatic mutations of the WT1 gene were found only occasionally in sporadic cases, although constitutional mutations of this gene are clearly associated with predisposition. It has been suggested that abnormal splicing may be another m...
