1. DNA checkpoint override and redox signaling in Schizosaccharomyces pombe
Abstract : 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. READ MORE

2. The ABC of the cell cycle : roles of the mammalian Cdc25 isoforms
Abstract : Cell cycle progression is mediated by Cyclin dependent kinases (Cdks) in complex with Cyclins. The activity of the Cyclin-Cdk complexes is regulated through a variety of levels: expression and proteolysis of Cyclins, binding of inhibitors, phosphorylations and subcellular localization.

3. Regulation of CDK dephosphorylation in mitotic entry
Abstract : Cell cycle progression is orchestrated by the activity of a Cyclin dependent kinase (Cdk) in complex with a Cyclin. The key regulator of early mitotic events is the Cyclin B1/Cdk1 complex. In G2, Cyclin B1/Cdk1 is kept inactive by phosphorylation in the active site of Cdk1. READ MORE

4. Computer Simulation of Protein Tyrosine Phosphatase Reaction Mechanisms and Dihydrofolate Reductase Inhibition
Abstract : Protein tyrosine phosphatases catalyse the hydrolysis of phosphotyrosine residues in proteins, which is an important reaction in the cell signalling system. The three dimensional structure of such a protein tyrosine phosphatase has been used in a computational study of the reaction mechanism at the atomic level. READ MORE

5. Characterization of candidate disease genes from human chromosomes 11g13 and 22q
Abstract : Two regions of the human genome, 11q13 and 22q, have been shown to harbor numerous disease-related genes, among them tumor suppressor genes (TSGs). The aim of this project was to construct transcription maps within these chromosomal segments, and thus provide a basis for further analysis of some of the genes for their involvement in disease-related processes.
