Host-virus interactions of mammalian endogenous retroviruses
Farkašová, Helena ; Elleder, Daniel (advisor) ; Hirsch, Ivan (referee) ; Mělková, Zora (referee)
Endogenous retroviruses (ERVs) originate by germline infection and subsequent mendelian inheritance of their exogenous counterparts. With notable exceptions, all mammalian ERVs are evolutionarily old and fixed in the population of its host species. Some groups of retroviruses were believed not to be able to form endogenous copies. We discovered an additional endogenous Lentivirus and a first endogenous Deltaretrovirus. Both of these groups were previously considered unable to form endogenous copies. Endogenous lentiviruses were discovered only recently and are still quite rare. These are still just small pieces of evidence insufficient to give a broader picture about the history of virus endogenization. We described a novel endogenous Lentivirus in the genome of Malayan colugo (Galeopterus variegatus) denoted ELVgv (endogenous Lentivirus of G. variegatus). Based on several analyses we proved that this is the oldest Lentivirus discovered up to date and confirmed its presence in the only other extant species of Dermoptera - Cynocephalus volans. Endogenous deltaretroviruses were the last group without a single endogenous member. We detected the remnants of endogenous Deltaretrovirus in the genome of Natal Long-fingered bat (Miniopterus natalensis). However, this sequence was present in the genome only in one...
