Testicular Degeneration of Transgenic Porcine Model of Huntington's Disease
 Skřivánková, Monika ; Motlík, Jan (advisor) ; Roth, Jan (referee) ; Petr, Jaroslav (referee)
Huntington's disease is an autosomal dominant neurodegenerative disorder caused by an extended (≥36) CAG repeat in the huntingtin gene. Its hallmark is brain athrophy, but huntingtin is widely deposited in all tissues of the body, most notably in the brain and testes. Its pathogenic effect is conditioned by the formation of cytotoxic forms of aggregates and fragments, which occur in both brain and peripheral tissues. Testicular atrophy has been demonstrated in postmortem samples from human patients with Huntington's disease and in transgenic mouse models. We investigated reproductive decline in a large animal model of Huntington's disease. A transgenic (tgHD) minipig model was created by inserting a lentiviral vector into the genome of a pig. Vector contained a truncated form of the N terminal part of huntingtin gene. Boars of this transgenic line showed a reduced ability to produce offspring from 13 months of age. We confirmed apoptosis of seminiferous epithelial cells and Sertoli cells, and a production of morphologically damaged spermatozoa, which were unable to efficiently fertilize the oocyte under in vitro conditions. We found a reduction of mitochondrial metabolism parameters in the sperm of tgHD boars. These changes were not dependent on the age of the boars., It is directly related to the...
