1. Linear and Branched Chitosan Oligomers as Delivery Systems for pDNA and siRNA In Vitro and In Vivo
Sammanfattning : In this thesis, chitosan, a biocompatible polysaccharide that has been approved as a food additive was selected as a platform for the development of safe, efficient non-viral gene delivery systems to mammalian cells. Previously, chitosan-based gene formulations had been generally associated with high molecular weight chitosans, which were poorly characterised in terms of molecular weight distribution and degree of acetylation.

2. Chimeric gene delivery vectors : Design, synthesis, and mechanisms from transcriptomics analysis
Sammanfattning : Delivery of nucleic acid is a promising approach for genetic diseases/disorders. However, gene therapy using oligonucleotides (ONs) suffers from low transfection efficacy due to negative charges, weak cellular permeability, and enzymatic degradation. LÄS MER
3. Characterization of nucleic acid delivery with fatty acid modified cell-penetrating peptide nanoparticle formulations
Sammanfattning : Recent advances with techniques used for manipulating gene expression have brought us to an era where various gene therapeutic approaches are becoming common therapeutic tools for many previously incurable diseases. The main factor impeding the wider translation of gene therapy is that the active pharmaceutical ingredients used for interfering with gene expression are based on nucleic acids and synthetic oligonucleotides and such molecules do not readily reach their intracellular targets due to their physicochemical properties and therefore they require delivery vectors to cross the cell membrane.

4. Regulating Gene Expression to Promote Osteoblastic Differentiation of Stem Cells
Sammanfattning : Bone is a tissue that heals by itself, unless the defect is too large (critical size). Today, novel regenerative medicine approaches have emerged as an alternative to treat such defects. This thesis explores alternative therapeutic strategies for bone tissue engineering which are biocompatible and clinically translatable. LÄS MER
5. Nucleoside analoge cytotoxicity-focus on enzyme regulation, metabolism, and mechanisms of resistance
Sammanfattning : The aim of this thesis was to determine the role of nucleoside analog activating and deactivating enzymes in nucleoside analog metabolism and resistance development. Nucleoside analogs are anti-cancer drogs and are often used to treat different leukemias, attributably to presence of high levels of nucleoside analog activating enzymes in hematopoietic cells.
