Screening for the HCV IRES interacting proteins
 Roučová, Kristina ; Pospíšek, Martin (advisor) ; Kuthan, Martin (referee)
Hepatitis C virus (HCV) is a worldwide spread pathogen infecting up to 3 % of the human population. Nowadays, research of new drugs against this virus is focused on the individual steps in its life cycle, including the translation initiation. In the case of HCV translation initiation is dependent on the internal ribosome entry site (IRES). Besides of components of the translational machinery also other components of the cell, so called IRES trans-acting factors (ITAF), contribute to its proper progress. This work continues in previous research of our laboratory focused on searching for new ITAF. In order to search for potential ITAF increasing HCV IRES activity new recombinant plasmid vectors and reference strains were prepared and selection conditions of the selection system were optimized. The differences in the growth characteristics of the reference strains were analyzed and quantified under selective and non-selective conditions. A set of pilot high efficiency transformations of the yeast strain pJ69-4A carrying bicistronic construct with HCV IRES were conducted using human expression cDNA library in order to optimize the efficiency of transformation and selection conditions and to attempt to identify new ITAF. Several dozens of randomly selected clones from these transformations obtained under...
