1. 1. Tracking single molecules in uncharted territory : A single-molecule method to study kinetics in live bacteria

   Författare :Javier Aguirre Rivera; Magnus Johansson; Dmitri N. Ermolenko; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; single-molecule; protein synthesis; fluorescence microscopy; antibiotics; aminoglycosides; macrolides; apramycin; gentamicin; paromomycin; S13; translation; bacteria; Molekylär biovetenskap; Molecular Life Sciences;

   Sammanfattning : The synthesis of proteins, also known as translation, is a fundamental process in every living organism. The steps in the translation of genetic information to functional proteins have been meticulously studied, mostly using in vitro techniques, yielding a detailed model of their mechanisms. LÄS MER

3. 2. Structural Decorations in Viruses : Unraveling Acquired Functional Structures in Icosahedral RNA Virus Capsids

   Författare :Han Wang; Kenta Okamoto; Sarah Butcher; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Viruses; RNA viruses; capsid; structure; cryo-EM; Molekylär biovetenskap; Molecular Life Sciences;

   Sammanfattning : Viruses have a profound impact worldwide, posing challenges to animal welfare, agriculture, human health, and the ecosystem. This thesis examines the realm of non-enveloped icosahedral double-stranded (ds)RNA and single-stranded (ss)RNA viruses through three studies. LÄS MER

4. 3. The role of non-coding single-stranded oligonucleotides on Respiratory syncytial virus infection

   Författare :Sandra Axberg Pålsson; Anna-Lena Spetz; Annika Karlsson; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Respiratory syncytial virus RSV ; single-stranded oligonucleotide ssON ; small non-coding RNA sncRNA ; nucleolin; virus infection; antiviral; molekylär biovetenskap; Molecular Bioscience;

   Sammanfattning : Respiratory syncytial virus (RSV) is an enveloped RNA virus of the Pneumoviridae family. RSV is reported to infect host cells by receptor-mediated endocytosis, also called clathrin-dependent endocytosis. Many reports indicate that the virus utilizes the host receptor nucleolin for entry.

5. 4. Guardians of the genome : Connecting chromatin structure and genome integrity in Saccharomyces cerevisiae

   Författare :Stefanie Lena Bauer; Stefan U. Åström; Brian Luke; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; molekylär biovetenskap; Molecular Bioscience;

   Sammanfattning : Branched DNA structures arise during recombination and during other DNA repair processes such as repair of stalled replication forks. One branched structure, the Holliday Junction (HJ), is a four-way junction that can connect sister chromatids or homologous chromosomes. We show a physical interaction between the HJ-cleaving enzyme Yen1 and Uls1. LÄS MER

7. 5. The impact of cytochrome P4501-inhibitors on aryl hydrocarbon receptor signaling

   Författare :Johanna Bengtsson; Emma Wincent; Ulf Rannug; Malin Celander; Stockholms universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; molekylär biovetenskap; Molecular Bioscience;

   Sammanfattning : The aryl hydrocarbon receptor (AHR) best known as a ligand-activated transcription factor that mediates toxic responses to xenobiotics such as dioxins, is also activated by certain endogenous compounds. Activation of the AHR up-regulates transcription of a large number of genes, including those encoding members of the cytochrome P450 1 family of enzymes (CYP1s). LÄS MER
