1. DNA checkpoint override and redox signaling in Schizosaccharomyces pombe
Sammanfattning : This thesis covers intracellular stress signaling through genotoxic stress, overriding of checkpoint control, as well as cellular redox status in hypoxic and oxidative stress Papers I and II: Caffeine has been shown to override cell cycle checkpoints in humans as well as in the fission yeast Schizosaccharomyces pombe. Understanding of the mechanism may aid in the development of compounds with similar overriding mechanisms for sensitization in cancer therapy. LÄS MER
2. Replication Dynamics in the DNA Damage Response
Sammanfattning : Faithful DNA replication is essential and the induction of replication stress may have profound effects on genomic integrity. This is demonstrated by the formation of DNA double strand breaks (DSBs), considered to be the most toxic DNA lesions, at stalled replication forks. LÄS MER
3. From oncogenic replication stress to drug resistance : F-box proteins as signalling hubs in cancer
Sammanfattning : Cancer arises from cells that acquire genetic and epigenetic changes during the course of a, sometimes decades-long, somatic evolutionary process. These changes result in deregulation of a multitude of cellular processes leading to novel capabilities, often referred to as hallmarks of cancer, and a strong selective advantage for these cells albeit at a dramatic cost to the organism as a whole.

4. Interactive antiproliferative mechanisms when 5-fluorouracil is combined with cisplatin or ionizing radiation : an in vivo and in vitro experimental study
Sammanfattning : Results from clinical studies and experimental investigations have given evidence of a synergistic effect when 5- fluorouracil (5-FU) has been combined with radiation or cisplatin (CDDP). From earlier experiments performed by the research team we know, that addition of S-FU to CDDP can synergistically increase the antiproliferative effect. LÄS MER
