1. 1. Post-transcriptional regulation by RNases in Streptococcus pyogenes

   Författare :Anne-Laure Lécrivain; Emmanuelle Charpentier; Bernt Eric Uhlin; Tracy Nissan; Ciarán Condon; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Post-transcriptional regulation; mRNA decay; RNA sequencing; RNase Y; RNase III; YhaM; PNPase; RNase R; RNase J1; Streptococcus pyogenes.; molekylärbiologi; Molecular Biology;

   Sammanfattning : Ribonucleases (RNases) are proteins that adjust cellular RNA levels by processing RNA transcripts, leading to their stabilization or degradation. RNases are grouped based on their ability to cleave the transcript internally (endoRNases) or degrade the transcript starting from the ends (exoRNases). LÄS MER

3. 2. Conformationally Constrained Nucleosides, Nucleotides and Oligonucleotides : Design, Synthesis and Properties

   Författare :Dmytro Honcharenko; Jyoti Chattopadhyaya; Piet Herdewijn; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bioorganic chemistry; antisense oligonucleotides; conformationally constrained nucleosides; azetidine; aza-ENA; target affinity; RNase H; exonuclease stability; pyrene-functionalized nucleotides; fluorescence; mismatch discrimination; Bioorganisk kemi; Cell and molecular biology; Cell- och molekylärbiologi;

   Sammanfattning : This thesis is based on six original research publications describing synthesis, structure and physicochemical and biochemical analysis of chemically modified oligonucleotides (ONs) in terms of their potential diagnostic and therapeutic applications. Synthesis of two types of bicyclic conformationally constrained nucleosides, North-East locked 1',2'-azetidine and North locked 2',4'-aza-ENA, is described. LÄS MER

4. 3. Transcriptional regulation of the Epstein-Barr virus nuclear antigen 1 gene in latent and lytic stages of infection

   Författare :Henrik Zetterberg; Göteborgs universitet; []
   Nyckelord :Epstein-Barr virus; EBNA1; Burkitt s lymphoma; nasopharyngeal carcinoma; ; B-lymphocyte; transformation; transcriptional regulation;

   Sammanfattning : Epstein-Barr virus (EBV) is a lymphotropic herpesvirus that infects more than 90% of humans worldwide. The virus is the causative agent of infectious mononucleosis, a self-limiting lymphoproliferative disorder, and is also associated with a variety of malignancies including Burkitt's lymphoma (BL), Hodgkin's disease (HD), nasopharyngeal carcinoma (NPC), and lymphoproliferative disorders in immunocompromised individuals.

5. 4. Multifaceted RNA-mediated regulatory mechanisms in Streptococcus pyogenes

   Författare :Anaïs Le Rhun; Emmanuelle Charpentier; Franz Narberhaus; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Streptococcus pyogenes; small RNAs; CRISPR; Cas9; tracrRNA; RNases; gene expression; RNA sequencing; Infectious Diseases; infektionssjukdomar; mikrobiologi; Microbiology;

   Sammanfattning : Bacterial pathogens rely on precise regulation of gene expression to coordinate host infection processes and resist invasion by mobile genetic elements. An interconnected network of protein and RNA regulators dynamically controls the expression of virulence factors using a variety of mechanisms. LÄS MER
