چکیده

Mice have been used in ovarian cancer research mainly as hosts for cell lines derived from human ovarian tumors and ascites. Such models provided valuable information into the nature of metastatic ovarian cancer and possible treatment strategies. However, the complexity of genetic aberrations in human ovarian cancer cell lines precluded understanding of the initiating events responsible for ovarian cancer induction. Since the majority of ovarian cancer patients present at an advanced stage of the disease, it has been difficult to identify the precursor lesions that could be used to study the early morphologic and genetic changes in ovarian cancer. It is thought that the development of animal models in which ovarian cancer can be induced and studied during its early stages will enable better understanding of early ovarian cancer lesions and elucidate molecular events that support ovarian cancer progression. The difficulties in generating such models include the lack of an adequate ovaryspecific promoter, the uncertainty about the tissue of origin for different histologic types of ovarian cancer, and the deficiency in understanding the genetic aberrations responsible for ovarian cancer induction. In spite of these difficulties, the first advances toward generating mouse models for ovarian cancer have been made.

Generation of Cisplatin-Resistant Ovarian Cancer Cell Lines

Ovarian cancer is the most lethal gynecological cancer in which cisplatin-based treatment plays fundamental role as the first line chemotherapy option. However, development of platinum-resistance is a critical and poorly understood problem in ovarian cancer treatment. Although in vitro generation of platinum-resistant ovarian cancer cell lines is a long established approach to uncover the molec...

Modeling and simulation of ovarian cancer and tumor growth and spread in different stages of ovarian cancer according to the TNM system

Introduction: Ovarian cancer is caused by malignant changes in the cells of the ovary. In various studies, cancer has been regarded as a biological system that has a set of characteristics; therefore, presenting a model of this system can considerably help to study and predict the phenomena related to the growth and spread of cancer. This study attempted to model and simulate the growth and spr...

Failure to Demonstrate the Role of High Risk Human Papilloma Virus in Epithelial Ovarian Cancer

Background and Aims: Ovarian cancer is one of most common causes of cancer related women's mortalities. Human papilloma virus is a known factor concerning cervical cancer but its role in causing ovarian cancer is not yet verified. A few studies also identified HPV DNA in ovarian carcinoma tissues. However, some studies did not detect HPV DNA in ovarian carcinoma tissues. In this articl...

Evaluation of the inhibitory synergic effects of the Persian Gulf brittle star extract and taxol on ovarian cancer A2780cp

Paclitaxel is a current standard chemotherapeutic drug for ovarian cancer with several side effects. Recurrences of drug resistant clones have been considered the serious problem in the failure of chemotherapy. Medicinal marine natural products have been intensively proposed as diverse chemotherapeutic agents. Therefore there is an affinity to find efficient modality to overwhelm ovarian cancer...
