General Description of Wilm's Tumor 1.
Recognizes a 47-55kDa-tumor suppressor protein, identified as Wilm's Tumor (WT1) protein. The antibody reacts with all isoforms of the full-length WT1, also identifies WT1 lacking exon 2-encoded amino acids, frequently found in subsets of sporadic Wilm s tumors.WT1, a sporadic, familial pediatric kidney tumor, is genetically heterogeneous. Wilm s tumor is associated with mutations of WT1, a zinc-finger transcription factor that is essential for the development of the metanephric kidney, the urogenital system. The WT1 gene is normally expressed in fetal kidney, mesothelium,, its expression has been suggested as a marker for Wilm s tumor, mesothelioma. WT1 protein has been identified in proliferative mesothelial cells, malignant mesothelioma, ovarian carcinoma, gonadoblastoma, nephroblastoma,, desmoplastic small round cell tumor. Lung adenocarcinomas rarely stain positive with this antibody. WT1 protein expression in mesothelial cells has become a reliable marker for the diagnosis of mesotheliomas.

Wilm's Tumor 1 Previously Observed Antibody Staining Patterns

Observed Subcellular, Organelle Specific Staining Data:

Anti-WT1 antibody staining is expected to be primarily localized to the nucleoplasm.

Observed Antibody Staining Data By Tissue Type:

Variations in Wilm's Tumor 1 antibody staining intensity in immunohistochemistry on tissue sections are present across different anatomical locations. An intense signal was observed in myoepithelial cells in the breast, cells in the endometrial stroma in endometrium, glandular cells in the fallopian tube, cells in the glomeruli in kidney and cells in the seminiferous ducts in testis. More moderate antibody staining intensity was present in myoepithelial cells in the breast, cells in the endometrial stroma in endometrium, glandular cells in the fallopian tube, cells in the glomeruli in kidney and cells in the seminiferous ducts in testis. Low, but measureable presence of Wilm's Tumor 1 could be seen inglandular cells in the breast and epididymis, cells in the tubules in kidney, decidual cells in the placenta, trophoblastic cells in the placenta, glandular cells in the prostate and seminal vesicle, adipocytes in mesenchymal tissue, fibroblasts in mesenchymal tissue and cells in the red pulp in spleen. We were unable to detect Wilm's Tumor 1 in other tissues. Disease states, inflammation, and other physiological changes can have a substantial impact on antibody staining patterns. These measurements were all taken in tissues deemed normal or from patients without known disease.

Observed Antibody Staining Data By Tissue Disease Status:

Tissues from cancer patients, for instance, have their own distinct pattern of Wilm's Tumor 1 expression as measured by anti-Wilm's Tumor 1 antibody immunohistochemical staining. The average level of expression by tumor is summarized in the table below. The variability row represents patient to patient variability in IHC staining.

Sample Type breast cancer carcinoid cervical cancer colorectal cancer endometrial cancer glioma head and neck cancer liver cancer lung cancer lymphoma melanoma ovarian cancer pancreatic cancer prostate cancer renal cancer skin cancer stomach cancer testicular cancer thyroid cancer urothelial cancer
