1. Molecular Pathogenesis of Cervical Carcinoma : Analysis of Clonality, HPV16 Sequence Variations and Loss of Heterozygosity
Sammanfattning : A previous model of morphological pathogenesis assumed that cervical carcinoma is of monoclonal origin and progresses through multiple steps from normal epithelium via CINS into invasive carcinomas. The aim of this study was to investigate the molecular mechanism of pathogenesis of cervical neoplasia. LÄS MER
2. Targeting allelic loss in colorectal cancer
Sammanfattning : Targeted cancer therapy exploits molecular differences between tumor and normal cells to selectively kill cancer cells. Whereas targeting of activated oncogenes has proved clinically useful, few current therapies exploit loss-of-function mutations in tumor suppressor genes or in the genome at large. LÄS MER
3. Genotoxic effects of systemic chemotherapy in cancer patients, with special focus on the relation between MSI, LOH and development of secondary cancers
Sammanfattning : Systemic chemotherapy results in both phenotypic and genotypic side effects. Genotoxicity posed by chemotherapy is a major concern since it induces DNA damage and instability in the patients’ genome. LÄS MER
4. Genetic studies of neuroblastoma with emphasis on the apoptotic pathway
Sammanfattning : Aim: The objective of this thesis was to find genes and chromosomal regions involved in neuroblastoma (NB) tumor progression. NB is a childhood tumor of the sympathetic nervous system that generally occurs spontaneously. LÄS MER
5. Population History and Non-invasive Monitoring : Use of low copy number DNA in Conservation Genetics
Sammanfattning : Conservation genetics research is increasingly becoming an integrated part of the management of small and endangered populations. In this thesis I developed tools for genetic analysis of low copy number sources of DNA, such as old teeth from museum specimens as well as field-collected faeces and urine. LÄS MER
