(Master thesis / Hovedoppgave, 2004)Chromosome One Amplified Sequence 2 (COAS2) is a member of the cyclophilin family of proteins (Meza Zepeda et al., 2002). It has 84% amino acid homology to H. sapiens cyclophilin A, also known as Peptidylprolyl Isomerase ...
-
(Master thesis / Hovedoppgave, 2004)Autofagi er en viktig proteindegraderingsmekanisme i eukaryote celler, da den er hovedmekanismen for nedbrytning av cytosoliske proteiner og organeller når tilgangen på næringsstoffer er begrenset. I tillegg er autofagi ...
-
(Master thesis / Hovedoppgave, 2004)The disagreement between various immunoassays for the tumour marker carcinoembryonic antigen (CEA) is well known, and the discrepancies are explained by the co-measurement of the structurally related non-specific cross-reacting ...
-
(Master thesis / Hovedoppgave, 2004)The rbcL promoter of C. reinhardtii has been reported to lack a functional -35 consensus motif common to the ó70 type promoters found in prokaryotes and many plastid promoters, while retaining a conserved ó70 like -10 ...
-
(Master thesis / Hovedoppgave, 2004)ABSTRACT: A reporter gene was constructed consisting of the 5´ region of the C. reinhardtii rbcL gene from position –70 to +47, relative to the transcription start point, fused to the E. coli uidA(GUS) structural gene ...
-
(Master thesis / Hovedoppgave, 2005)DNA polymeraser er av fundamental betydning for levende organismer, ettersom de spiller en avgjørende rolle i replikasjon og reparasjon av DNA. I de siste årene er de blitt viktige genteknologiske verktøy, og varmestabile ...
-
(Master thesis / Hovedoppgave, 2005)Antimicrobial peptides produced by lactic acid bacteria (LAB) are extensively studied, but little is know about their three-dimensional structures. Solution structures of these peptides will be useful to gain information ...
-
(Master thesis / Masteroppgave, 2005)The major histocompatibility (MHC) class II molecules present peptides to the T cell receptor on CD4+ lymphocytes. The diversity of the epitopes presented depends critically on the processing of the ingested antigens, and ...

(Master thesis / Masteroppgave, 2005)
-
(Master thesis / Masteroppgave, 2005)Histone lysine methylation is considered to be a relatively stable modification associated with important functions in epigenetic gene control and for organizing chromatin domains. Genes encoding mammalian homologues of ...
-
(Master thesis / Masteroppgave, 2005)Covalent modifications of the DNA and histones through acetylation, phosphorylation, methylation, etc are central to gene regulation, recombination, DNA replication and many other processes in the cell. With respect to ...
-
(Master thesis / Hovedoppgave, 2005)In isolated rat hepatocytes, okadaic acid and cantharidin activate AMP-activated protein kinase (AMPK) by a naringin-sensitive and a naringin-resistant mechanism respectively, probably through inhibition of protein ...
-
(Master thesis / Hovedoppgave, 2005)Production of DNA damage is the basis of cancer treatments, such as radiotherapy. The limitation of the treatment dose tends to be how well the tumor and normal cell within the body can tolerate the therapy. In order to ...
-
(Master thesis / Masteroppgave, 2005)Abstract Nuclear receptors that work as heterodimers with RXR control several aspects of lipid metabolism. One such nuclear receptor, pregnane X receptor (PXR) is the molecular target for a wide variety of endogenous and ...
-
(Master thesis / Hovedoppgave, 2005)Vekstfaktorer og vekstfaktorreseptorer er med på å regulere vekst av celler via et nettverk av spesifikke intracellulære signalmekanismer. Binding av vekstfaktorer til reseptorer aktiverer reseptorene slik at signalkjeder ...
-
(Master thesis / Masteroppgave, 2005)NUCKS-proteinet ble oppdaget i 1985 av Anne Carine Østvold og hennes medarbeidere ved Biokjemisk Institutt, Universitetet i Oslo. NUCKS genet er klonet og proteinet nøye karakterisert, men dets biologiske funksjon er ...
-
(Master thesis / Hovedoppgave, 2005)Perfluoro oktansyre (PFOA) er en peroksisomal proliferator som er kjent for å også gi antiinflammatoriske reaksjoner. Virkningsmekanismen for stoffet i levende dyr er lite kjent. For å få en bedre forståelse av PFOAs ...
-
(Master thesis / Hovedoppgave, 2006)Epitelcellelinjen ”Madin-Darby canine kidney” (MDCK), er en velstudert polarisert cellelinje som danner et tett cellelag med separate apikale og basolaterale membranoverflater. For å opprettholde polariteten, må nysyntetiserte ...
-
(Master thesis / Masteroppgave, 2006)Transmissible spongiform encephalopathies (TSEs) are fatal, neurodegenerative diseases in human and animals, caused by prion protein (PrP). The functions of PrP and the basis of these diseases are still under debate. In ...
-
(Master thesis / Masteroppgave, 2006)Cancer is a disease resulting from an accumulation of acquired genetic mutations. The consequence is an uncontrolled growth of cells and disruption of normal control mechanisms. Complex chromosomal aberrations such as ...
