Directed evolution of an HIV-1 LTR specific recombinase for anti-retroviral therapy- a proof of concept study

Sarkar, Indrani 17 January 2007 (has links) (PDF)
The prospect of the work presented in this thesis has been to engineer Cre recombinase to recognize and recombine a sequence from an HIV-1 Long Terminal Repeat (LTR), characterize the recombination proficiency of the evolved recombinase in mammalian cells and explore the potential of the recombinase for a novel antiretroviral strategy.

Mutační a substituční tempo u sexuálních a klonáních forem: možný klíč k vysvětlení persistence sexu u modelové skupiny sekavců? / Mutation and substitution rates in sexual and asexual forms: a clue to the persistence of sex in a model group of Cobitis?

TITLE: Mutation and substitution rates in sexual and asexual forms: a clue to the persistence of sex in a model group of Cobitis? AUTOR: Jan Röslein DEPARTMENT: Ústav živočišné fyziologie a genetiky AVČR, v.v.i. SUPERVISOR: Mgr. Karel Janko, Ph.D. ABSTRACT: Subject of this thesis is to test several hypotheses about the evolution of asexual reproduction in model group of fish family Cobitis and its mutual competition among sexual and asexual forms, which touches one of the oldest unresolved issues of biology. Specifically, the work deals with the accumulation of non-synonymous mutations, which accelerated accumulation in the genome of clonal lineages theoretically leads to increased extinction compared with sexually reproducing populations (so-called. The theory of Muller's ratchet and Kondrashov's hatchet). This thesis is based on a normalized cDNA sequencing data from oocytes and liver tissue, which has served as a base matrix (generated based on non-normalized cDNA data) for transcriptome sequencing (RNAseq). Consequently, the RNAseq data have served as validation for acquired polymorphisms, detection of differential expression of allele- specific expression (ASE) hybrid biotypes. This diploma thesis balances among the edges of vast spectrum of hypotheses regarding the evolution of the genus hybrid...
