1. 1. RNA-mediated gene expression regulation

   Författare :Paula Petronela Groza; Francesca Aguilo; Yuri B. Schwartz; Silvia Remeseiro; Henrik Nielsen; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; RNA modifications; fibrillarin; 2 -O-methylation; translation; alternative splicing; METTL3; m6A; ZFP207; breast cancer; mouse ESCs; molekylärbiologi; Molecular Biology;

   Sammanfattning : The regulation of gene expression is a key mechanism that underlies all biological processes, from embryonic development to the onset and progression of various diseases, including cancer. A growing body of evidence places RNA molecules at the center of critical regulatory steps in gene expression. LÄS MER

3. 2. Chromosome-specific adaptations of RNA stability and the roles of the roX RNAs in dosage compensation

   Författare :Marie-Line Faucillion; Jan Larsson; Jean-Yves Roignant; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Drosophila melanogaster; dosage compensation; buffering; RNA stability; RNA decay; RNA half-life; RNA-seq; genome-wide; sex chromosomes; evolution; roX1; roX2; POF; MSL; molekylärbiologi; Molecular Biology;

   Sammanfattning : Sex chromosomes evolved from an ancient pair of autosomes and the Y chromosome lost most of its genetic information in the process. This created two kinds of genomic imbalances: the first one between males (XY) and females (XX) and the second one between the sex chromosomes and the autosomes (X:AA). LÄS MER

4. 3. Conformationally Constrained Oligonucleotides for RNA Targeting

   Författare :Qing Li; Jyoti Chattopadhyaya; Li-He Zhang; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; conformationally constrained nucleoside; antisense oligonucleotide; RNA affinity; nuclease stability; RNase H; RNA degradation; Chemistry with specialization in Bioorganic Chemistry; Kemi med inriktning mot bioorganisk kemi;

   Sammanfattning : A short oligonucleotide sequence as in a single-stranded antisense oligo nucleotides (AON) or in double-stranded small interfering RNAs (siRNA) can modulate the gene expression by targeting against the cellular mRNA, which can be potentially exploited for therapeutic purposes in the treatment of different diseases. In order to improve the efficacy of oligonucleotide-based drugs, the problem of target affinity, nuclease stability and delivery needs to be addressed. LÄS MER

5. 4. Nucleic Acids as Drug Targets - Influence of Platinum Complexes on Duplex Stability and Binding Kinetics

   Författare :Christopher Polonyi; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Anticancer drugs; platinum complexes; cisplatin; oxaliplatin; nucleic acid; RNA; DNA; duplex melting; thermodynamic stability; kinetics; non-coding RNA; miRNA; siRNA; wobble base pair; loop; BRCA1; mimic; luciferase assay;

   Sammanfattning : Gaining a detailed understanding of how human cells are affected by metal-based drugs is crucial, since these drugs have shown great potential in cancer treatment. Cisplatin is used to treat many different types of cancer, e.g. testicular, ovarian, melanoma, bladder, non-small cell lung cancer, small cell lung cancer, myelomas and lymphomas. LÄS MER

7. 5. Nucleic Acids as Drug Targets -Interactions of Platinum Complexes, Polyamines, and siRNA with DNA and RNA Models

   Författare :Margareta Hägerlöf; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kinetics; Kemi; Chemistry; AU-rich region; siRNA; Circular Dichroism; Polyamine; Modified Nucleoside; HPLC; Thermodynamic Stability; cisplatin; Hairpin; DNA and RNA conformation; RNA; DNA; Anticancer Drug; Platinum Complexes;

   Sammanfattning : Drugs targeting nucleic acids were studied in DNA and RNA model systems. The effects were investigated with respect to structural and thermodynamic influence, kinetics, and biological function. The drugs employed in this thesis were anticancer active platinum(II) complexes, polyamine derivatives, and siRNA. LÄS MER
