Hormonal Influences in the Pathogenesis of Ovarian Tumours

Funded Activity Summary

Ovarian cancer is one of the most common malignancies affecting the female reproductive system. We have found that two types of tumour of the ovary produce a hormone called inhibin; these tumours are also known to produce the steroid hormone estrogen. In these studies we are seeking to determine the genetic changes in the tumours that cause the production of these hormones. We suspect that these genetic changes are also the same changes which contribute to the development of the cancers. In order to identify these genes we will draw on our knowledge of the genes that are important in the controlof growth and hormone secretion in normal ovarian cells. To assist this molecular analysis we will use two ovarian cell lines in culture that have many of the features of the primary tumours including inhibin secretion. We will also use new techniques to scan over 500 genes involved in tumours in general to see whether we detect any unusual or distinctive patterns in this sub-group of tumours. A genome wide scanning technique will be used to seek changes in the DNA of the tumours, inparticular loss of genetic material or amplification of regions. Identification of the genetic changes within these tumours should enable better systems of classification, enhance prognostication and provide specific targets for the development of appropriate treatment strategies.
