Abstract:
Philosophiae Doctor - PhD<br>Introduction: Globally, there are over 190,000 new reported cases of ovarian cancers per annum. This comprises 3% to 4% of all cancers in women. Ovarian cancer is one of the leading causes of deaths in women. Ovarian cancer is the second most diagnosed gynaecological malignancy and over all the fifth cause leading to death among all types of cancer in the UK in 2004. More than 70% of epithelial ovarian cancers are diagnosed at an advanced stage. Consequently, the prognosis is poor and the mortality rate high. Thus, the survival rate is affected by how far the disea

Abstract:
Benign ovarian tumors and majority of epithelial ovarian cancers possess steroid receptors including estrogen receptors (ERs). However, the estrogen-ER signaling in ovarian carcinomas is not completely understood. Tumorigenesis is a multiple-step process involving dysregulated cell growth and metastasis. Tumor cells acquire the capacity of migration and invasion by temporal phenotypical and genotypical changes termed epithelial-mesenchymal transition (EMT). Considerable evidence implicates a mitogenic action of estrogen in early ovarian carcinogenesis. In contrast, its influence in the metasta

Abstract:
Ovulation is a putative risk factor for ovarian cancer, and may be attributed to proliferating ovarian surface epithelial (OSE) cells interacting with the extracellular matrix (ECM) during ovulatory wound repair. We investigated the effects of ECM and cellular density on OSE cell morphology, proliferation, and expression of c-Kit, a proto-oncogene expressed in 70% of ovarian tumours. Fibrillar collagen I caused significant changes in morphology and proliferation but monomeric ECM had no effect. Normal human ovaries co-expressed KIT, collagen I and fibronectin in 75% of abnormal OSE structures.

Ovarian cancer is the deadliest of all the gynecologic cancers and is known for its clinically occult and asymptomatic dissemination. Most ovarian malignancies are diagnosed in the late stages of the disease and the high rate of morbidity is thought to be due, in part, to the highly metastatic nature of ovarian carcinomas. Cancer metastasis relies on the ability of cells to migrate away from primary tumors and invade into target tissues. Though the processes are distinct, cancer cell invasion relies on the underlying migration machinery to invade target tissues. Cell migration requires the coo

Importantly, these can also be found in a significant proportion of adjacent non-malignant endometriotic lesions and, therefore, are likely early events in OCCC pathogenesis.

Epithelial ovarian cancer cells with low E-cadherin expression are more invasive, and the absence of E-cadherin expression in ovarian cancer is associated with poor prognosis and survival.

Abstract:
Glycosphingolipids (GSL) modulate several signal transduction processes controlling cell proliferation, survival, differentiation and transformation. Alterations in the expression of carbohydrate epitopes associated with GSL are frequent in tumors, and it has been hypothesized that GSL could play important roles in modulating some of the properties of tumor cells. The contribution of transformation-associated changes in GSL composition to the tumor phenotype are very complex and not fully elucidated, and likely implies heterogeneous molecular mechanisms. However, at least two well established
