PI: G. Bea A. Wisman, PhD
Bea Wisman is a molecular biologist and obtained her PhD at the Departments of Medical Oncology and Gynecologic Oncology, University Medical Center Groningen in the laboratory of Prof dr EGE de Vries. The main subject of her PhD was to study the role of telomerase in human diseases with an emphasis on gynecological cancers. During her PhD, she received a KWF travel grant to perform research at the Beatson Institute (Glasgow, UK) in the lab of Dr. N. Keith. After her PhD, she remained interested in translational research and obtained a post-doc position in the Department of Gynecologic Oncology (head: Prof. AGJ van der Zee) and performed research on ovarian cancer and cervical cancer. In 2005, she became project leader in the lab of Prof. AGJ van der Zee. Over the last years, studies have been performed on the detection and (prognostic) significance of cell biological parameters in gynecologic cancers with a special interest in epigenetics. In 2004, she was a visiting scientist in the lab of Prof. D Sidransky (Johns Hopkins University School of Medicine, Baltimore, USA).
1. Improvement of the current population-based cervical cancer screening
Cervical cancer is an important cause of death in women worldwide. Cervical carcinogenesis is highly associated with high-risk human papillomavirus (hr-HPV) infections. Cytomorphological examination of cervical smears is a widely applied, though not ideal screening method for cervical cancer and its precursors (cervical intraepithelial neoplasia (CIN), because of its non-optimal sensitivity. Hr-HPV testing has been suggested to improve cervical cancer screening. However, the specificity of hr-HPV testing, especially in a young screening population is relatively low. Additional objective markers are needed to improve sensitivity and specificity for cervical cancer screening. Methylation of tumor suppressor genes contributes to an immortalized phenotype by silencing expression of genes responsible for control of normal cell differentiation and/or inhibition of cell growth. In addition to the functional implications of gene inactivation in tumor development, these methylation patterns represent excellent targets for novel diagnostic approaches based on methylation sensitive PCR (MSP). Promoter hypermethylation analysis might improve sensitivity and specificity for cervical cancer screening. We search for specific and sensitive methylation markers by several genome-wide approaches resulting in the identification of a methylation panel of genes, which will improve population-based cervical cancer screening. In addition, the role of these genes in cervical carcinogenesis is analyzed.
2. Identification of novel genes and pathways in the response to therapy
The response to chemotherapy (in ovarian cancer) and chemoradiation (in cervical cancer) is mainly determined by genes belonging to pathways involved in cell cycle, DNA repair and apoptosis. Silencing of tumor suppressor genes by hypermethylation of CpG islands in promoter regions of these genes is a common feature of human cancer. By the analysis of protein expression and DNA promoter hypermethylation on patient samples and cancer cell lines, genes and/or pathways will be identified and validated by their relation in the response to chemotherapy or chemoradiation. Ultimately, we will modulate these genes/pathways in order to improve the response on therapy.
Research is performed in collaboration with groups within the department and institute (UMCG/RUG) as well as in national and international settings. Funding has been obtained from the Dutch Cancer Society and OncoMethylome Sciences, S.A. Liege, Belgium.
