PURPOSE To elucidate the molecular mechanisms contributing to the unique clinicopathologic characteristics of mucinous ovarian carcinoma, global gene expression profiling of mucinous ovarian tumors was carried out. EXPERIMENTAL DESIGN Gene expression profiling was completed for 25 microdissected mucinous tumors [6 cystadenomas, 10 low malignant potential (LMP) tumors, and 9 adenocarcinomas] u...

BACKGROUND We showed there are specific ALDH1 autoantibodies in ovarian autoimmune disease and ovarian cancer, suggesting a role for ALDH1 in ovarian pathology. However, there is little information on the ovarian expression of ALDH1. Therefore, we compared ALDH1 expression in normal ovary and benign and malignant ovarian tumors to determine if ALDH1 expression is altered in ovarian cancer. Sinc...

PURPOSE Jab1 (Jun activation domain-binding protein 1) has been described as a coactivtor of AP1 transcription factor, and is a subunit of a large protein complex (called the COP9 signalosome). Recent study (K. Tomoda et al., Nature (Lond.), 398: 160-165, 1999) found that Jab1 protein can cause breakdown of p27(kip1) protein in mammalian cells. To investigate whether Jab1 expression is correlat...

Epithelial carcinoma of the ovary is one of the most common gynecological malignancies and the fifth most frequent cause of cancer death in women. Currently blood test of advanced epithelial tumors are reflected in a high level of CA 125 antigen. However, it is not a good marker for early stage tumors, and may yield false positives. Clearly, there is a need for better understanding of the molec...

Most human ovarian tumors are classified into one of several categories based on presumed histogenesis and direction of differentiation. Separate categories are reserved for neoplasms composed of cells of several origins and for nonneoplastic disorders that simulate neoplasms. Using the World Health Organization Histologic Classification of Ovarian Tumors, histologic features for common and rar...

BACKGROUND Peritoneal dissemination of ovarian tumors is a major prognostic parameter in ovarian malignancies. Analysis of peritoneal washing cytology serves as a useful predictor of ovarian surface involvement and peritoneal metastasis even in the absence of clinical omental spread. The aim of the current study is to correlate peritoneal cytology with various histologic features of ovarian can...

OBJECTIVE To evaluate the value of individual and combined measurement of human epididymis protein 4 (HE4) and cancer antigen 125 (CA-125) in the diagnosis of ovarian cancer. METHODS A clinical case-control study was performed in which the levels of serum HE4 and CA-125 of subjects with malignant, borderline, benign ovarian tumors and healthy women were measured before surgery. An immunohisto...
