Clear cell carcinoma is an uncommon subtype of ovarian carcinoma, accounting for 10% of cases. Clear cell carcinoma typically presents with stage I or II disease, and in this setting prognostic markers could aid in management decisions, in particular the decision to treat with adjuvant chemotherapy. We tested whether expression of insulin-like growth factor(More)
Insulin-like growth factor-II messenger RNA (mRNA)-binding protein-3 (IMP-3), also known as K homology domain-containing protein overexpressed in cancer (KOC) and L523S, is a member of the insulin-like growth factor-II mRNA-binding protein family and is expressed during embryogenesis and in some malignancies. IMP-3 expression in melanocytic neoplasms has(More)
The efficacies of targeted therapies for cancer treatment are dependent on the expression of the targeted molecule in the tumors of the treated patient population. Immunohistochemistry is an attractive assay format for determining protein expression in biopsies of solid tumors, and is widely used in pathology laboratories. An optimized immunohistochemistry(More)
A number of malignancies, including high-grade neuroendocrine carcinomas of the lung, have been reported to express K homology domain containing protein overexpressed in cancer (KOC), a member of the insulin-like growth factor messenger RNA-binding protein (IMP) family also known as L523S and IMP3. KOC acts to promote tumor cell proliferation by enhancing(More)
RNA-binding protein IMP3 is a KH-domain-containing protein and a member of the insulin-like growth factor messenger RNA-binding protein family. It is identical to K-homology protein overexpressed in cancer that was identified through screening for genes differentially expressed between benign pancreatic tissue and pancreatic cancer. Several studies have(More)
K homology domain containing protein overexpressed in cancer (KOC) is a member of the insulin-like growth factor (IGF) messenger RNA-binding protein family and is expressed during embryogenesis and in certain malignancies. KOC, known as L523S and IGF messenger RNA-binding protein 3, was shown to be frequently expressed in high-grade neuroendocrine(More)
Depending on the Breslow depth of the primary melanoma, sentinel lymph node biopsy is considered as standard of care for the staging of cutaneous melanoma, and is one of the most important prognostic factors. The histologic analysis of these specimens becomes difficult to interpret when benign intranodal nevic cells mimic metastases. Insulin-like growth(More)
Histopathologic distinction among small-cell carcinoma (SCC), pancreatic endocrine tumor (PET), and gastrointestinal carcinoids metastasized to the liver in needle core biopsies can be extremely challenging because of limited material, crush artifact, and lack of detailed clinical history. In this study, a total of 61 surgically resected or biopsied(More)
AIMS To elucidate the expression and regulation of survivin in normal tissues. METHODS AND RESULTS A novel monoclonal antibody (12C4) to survivin was generated. Application of this antibody to determine survivin expression in human normal adult tissues revealed that most adult tissues do not express survivin and, where it is present, survivin is largely(More)
Insulin-like growth factor II mRNA binding protein 3 is an oncofetal protein that is expressed in multiple malignancies. This study aimed to determine the correlation of insulin-like growth factor II mRNA binding protein 3 expression with histologic grade of lung adenocarcinoma. Eighty-nine cases, including 11 atypical adenomatous hyperplasias, 10 pure(More)
