Deoxyribonucleic acid (DNA) carries all the genetic information of a cell. Ribonucleotide reductase (RNR) provides balanced pools of all four dNTPs, the building blocks of DNA. These building blocks are needed during DNA synthesis and repair. A failure in the control of the dNTP levels and/or their relative amounts leads to cell death or genetic abnormalities.

Regulation of the Expression of Mouse Ribonucleotide Reductase Small Subunit at the Levels of Transcription and Protein Degradation
Malaria, an infectious disease caused by Plasmodium parasites, is one of the major world-scale health problems. Despite the efforts aimed at finding an effective way to control the disease, the success has been thwarted by the emergence of parasite drug resistance and mosquito resistance to insecticides. This thesis focuses on the genetic analysis of resistance to murine malaria induced by the lethal Plasmodium berghei ANKA using a wild-derived-inbred strain (WDIS).
Aromatase is the enzyme that catalysis the conversion of androgens into estrogens. It´s a member of P450 cytochrome family and is encoded by the CYP19-gene. The enzyme aromatase has an important role in regulating physiological and behavioral sexual mechanisms. This includes for instance activation, motivation and maintenance of the reproductive behaviors.
Monogenic disorders offer a possibility for studies of genetic disturbances in hearing impairment—a knowledge which could be essential for development of future treatment options. In this thesis, the underlying genetic disturbances in neurofibromatosis 2 (NF2) and familial Meniere’s disease (FMD) were evaluated, and familial X-linked hearing impairment was described from a clinical point of view.
Type 1 diabetes mellitus (T1DM) is an autoimmune disease in which T-cells and macrophages invade the islets of Langerhans and selectively destroy the insulin producing β-cells, either directly or through the secretion of e.g. cytokines and nitric oxide (NO). This thesis has studied possible strategies to prevent T1DM.
Novel Interactors of X-linked Inhibitor of Apoptosis Protein: Expression and Effects on Tumor Cell Death
Programmed cell death, or apoptosis, has during the last decade received a lot of attention due to its involvement in a large number of pathological conditions. Since death is always irreversible, it is important for cells to fully control the initiation and execution of this process. One of many apoptosis-regulatory proteins is XIAP.
The main aims were to: explore whether there is a relation between doctors’ ability to identify patients’ worry and wish for information and self-efficacy with regard to communicating with patients about difficult matters; describe which cues doctors consider when estimating patients’ worry and wish for information, and investigate whether there is a relation between patients’ satisfaction with doctors’ care and patients’ psychosocial function
The use of catanionic drug-surfactant mixtures was proven to be an efficient novel method of obtaining prolonged drug release from gels. It was shown that various commonly used drug compounds are able to form catanionic mixtures together with oppositely charged surfactants. These mixtures exhibited interesting phase behaviour, where, among other structures, vesicles and large worm-like or branched micelles were found.
