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

    Author : Margareta Hägerlöf; Biokemi och Strukturbiologi; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. Cationic Interactions with Nucleic Acids With Focus on Anticancer Active Platinum(II) Complexes

    Author : Åse Sykfont Snygg; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; in-line cleavage; Cisplatin; oxaliplatin; circular dichroism; DENSPM; polyamines; siRNA; pseudoknot; RNA; thermal melting; anticancer active Pt II complex; DNA;

    Abstract : It is well documented that the antitumour activity of the Pt(II)-complex cisplatin, and similar anticancer active complexes, is a result of metalation of DNA, and thereby inhibition of cell proliferation. Since nucleic acids are polyanions at physiological pH, the rate of adduct formation with positively charged complex, as the hydrolyzed Pt(II) complexes studied in this work, is influenced by the ionic environment surrounding the polymer.

  5. 3. Hepatitis B virus RNA in serum and liver tissue - quantification using digital PCR

    Author : Kasthuri Prakash; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hepatitis B virus; NTCP; HBV DNA; HBV RNA; subviral particles; integrations; droplet digital PCR;

    Abstract : Hepatitis B virus (HBV) infection is a global health issue that is responsible for approximately 900,000 deaths each year, by inducing liver cirrhosis and hepatocellular carcinoma (HCC). A few markers are used to classify HBV infection and monitor treatment efficacy, including HBV DNA, surface antigen (HBsAg) and e antigen (HBeAg) in serum as well as HBV DNA and RNA in liver tissue.

  6. 4. RNA systems for NMR studies in vitro and in vivo

    Author : Hannes Feyrer; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : NMR spectroscopy is an excellent tool to study the structure-function relationship of RNA. Such measurements are usually performed in vitro, which requires large amounts of isotope- labeled sample in high purity and can give access to individual atoms, structure of the molecule and conformational dynamics.

  7. 5. Expanding the alphabet of fluorescent nucleic acid base analogues: Characterization of new members

    Author : Anke Dierckx; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fluorescent adenine analogue; fluorescent DNA base analogue; duplex stability; Fluorescence quantum yield; circular dichroism; B-DNA;

    Abstract : Fluorescence has proven to be a powerful tool for studying structure, dynamics and interactions of biomolecules such as proteins, RNA and DNA. However, since the natural DNA/RNA nucleobases are virtually non-fluorescent, there is a need for developing fluorescent nucleic acid markers. READ MORE
