The matrix metalloproteinases (MMPs) and the tissue inhibitors of metalloproteinases (TIMPs) have been associated with ovarian tissue remodelling and development of ovarian tumours. With respect to ovarian cancer, the majority of previous studies were performed on serous and mucinous tumours, and little is known about clear cell carcinoma, which shows unique characteristics among ovarian cancer...

Primary peritoneal papillary serous carcinoma is a rare primary malignancy diffusively involving the peritoneum of abdomen and pelvis. Epithelial ovarian cancers and primary peritoneal cancers arise from the common germinal epithelium which develops from the coelomic epithelium. Due to a common embryonic origin of the ovary and the peritoneum, carcinoma of the ovary and primary peritoneal carci...

BACKGROUND Dysregulation of BCL6 plays critical oncogenic roles and facilitates tumorigenesis in various malignancies. However, whether the aberrant expression of BCL6 in ovarian carcinoma is associated with malignancy, metastasis or prognosis remains unknown. Our study aimed to investigate the expression of BCL6 in ovarian carcinoma and its possible correlation with clinicopathological feature...

Ovary is one of the main endocrine glands, also the source of female fertility and at the same time the organ with the largest number of histological varieties of malignant tumors. The most frequent among primary neoplasms are epithelial tumors. Secondary tumors of the ovary arise by direct tumor extension from adjacent organs or tissues, by transtubal or transperitoneal route, as well as hemat...

Ovarian carcinomas of epithelial type comprise a heterogeneous group of neoplasms, each with a different underlying pathogenesis and natural behaviour. Accurate classification of ovarian carcinomas is important since each type may be associated with a different behaviour, natural history and outcome. Precise classification is also critical to determine whether alternative therapeutic strategies...

The first tissue-specific angiogenic molecule, endocrine gland-derived vascular endothelial growth factor (EG-VEGF), was identified recently in human ovary, raising hopes of developing tumor type-specific angiogenesis inhibitors. In the present study, we analyzed the expression of EG-VEGF mRNA in normal human tissues and ovarian neoplasms by quantitative real-time reverse transcription-PCR. EG-...

We report a pedigree in which three sisters had a particular type of ovarian cancer, small cell carcinoma of the hypercalcaemic type. This rare type of ovarian carcinoma is now well characterised by clinical and pathological findings and is well distinguished from other ovarian epithelial tumours and ovarian germ cell tumours. The occurrence of this rare type of cancer in several members of the...

Clear cell carcinoma of ovary is uncommon ovarian tumour that arises from surface epithelium of ovary. It has well-known association with ovarian endometriosis. We report here the first case of bilateral clear cell carcinoma of ovaries in a 40-year-old woman with a 17-year history of bilateral ovarian endometriosis. In addition, during the longstanding duration of the endometriosis, the patient...

Ovarian serous carcinoma is a highly aggressive neoplastic disease in women. Our previous studies have demonstrated Notch3 gene amplification and upregulation in many ovarian serous carcinomas and Notch pathway activity contributed to drug resistance. Among different Notch3 ligands, Jagged1 is most dominant in ovarian cancer, and Notch3 pathway activity correlated with Jagged1 expression level ...

Non-motile cilia are thought to be important determinants of the progression of many types of cancers. Our goal was to identify patterns of cilia gene dysregulation in eight cancer types (glioblastoma multiforme, colon adenocarcinoma, breast adenocarcinoma, kidney renal clear cell carcinoma, lung squamous cell carcinoma, lung adenocarcinoma, rectal adenocarcinoma, and ovarian cancer) profiled b...
