1. 16. Post-Transcriptional Regulation of the Murine Inducible Nitric Oxide Synthase Gene

   Författare :Malin Söderberg; Matti A. Lang; Françoise Raffalli-Mathieu; Eeva Moilanen; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biochemistry; iNOS; inducible nitric oxide synthase; gene regulation; post-transcriptional; mRNA stability; RNA-protein interactions; dexamethasone; murine; heterogeneous nuclear ribonucleoprotein; hnRNPI; hnRNPL; Farmaceutisk biokemi; Pharmaceutical biochemistry; Farmaceutisk biokemi;

   Sammanfattning : Large amounts of nitric oxide (NO) are produced by the inducible nitric oxide synthase (iNOS) upon inflammatory stimuli. NO is a multifaceted molecule, which may have beneficial effects as an antimicrobial agent in the immune defense, or cytotoxic effects in chronic inflammations, manifested as e.g. arthritis and asthma.

3. 17. Post-transcriptional regulation after stress in Schizosaccharomyces pombe

   Författare :Daniel Nilsson; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Post transcriptional regulation;

   Sammanfattning : Post transcriptional regulation is part of the gene expression control and is important for many cellular processes. It influences how mRNAs are selected for translation, degradation or storage. In this thesis, I describe some of the known mechanisms for transcriptional regulation in S. LÄS MER

4. 18. Small RNAs, Big Consequences : Post-transcriptional Regulation and Adaptive Immunity in Bacteria

   Författare :Mirthe Hoekzema; Gerhart E. H. Wagner; Magnus Lundgren; Kai Papenfort; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; small RNA; sRNA; non-coding RNA; Hfq; gene regulation; post-transcriptional regulation; biofilm; OmrA; OmrB; toxin-antitoxin; TisB; IstR-1; Persisters; CRISPR-Cas; CRISPR-Cas adaptation reporter; Escherichia coli; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

   Sammanfattning : It is nowadays widely accepted that non-coding RNAs play important roles in post-transcriptional regulation of genes in all kingdoms of life. In bacteria, the largest group of RNA regulators are the small RNAs (sRNAs). LÄS MER

5. 19. 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

7. 20. Transcriptional regulation of mouse ribonucleotide reductase

   Författare :Anna Elfving; Lars Thelander; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ribonucleotide reductase; promoters; cell cycle; transcriptional regulation; primer extension; protein purification; EMSA; Biochemistry; Biokemi; medicinsk biokemi; Medical Biochemistry;

   Sammanfattning : All living organisms are made of cells and they store their hereditary information in the form of double stranded DNA. In all organisms DNA replication and repair is essential for cell division and cell survival. These processes require deoxyribonucleotides (dNTPs), the building blocks of DNA. LÄS MER
