Promoter-Specific Expression and Imprint Status of Marsupial IGF2
In mice and humans, IGF2 has multiple promoters to maintain its complex tissue- and developmental stage-specific imprinting and expression. IGF2 is also imprinted in marsupials, but little is known about its promoter region. In this study, three IGF2 transcripts were isolated from placental and liver samples of the tammar wallaby, Macropus eugenii. Each transcript contained a unique 5' untransl...
متن کاملIdentification of tammar wallaby SIRH12, derived from a marsupial-specific retrotransposition event
In humans and mice, there are 11 genes derived from sushi-ichi related retrotransposons, some of which are known to play essential roles in placental development. Interestingly, this family of retrotransposons was thought to exist only in eutherian mammals, indicating their significant contributions to the eutherian evolution, but at least one, PEG10, is conserved between marsupials and eutheri...
متن کاملNutrition of marsupial herbivores.
Mammalian herbivores can be divided into two groups on the basis of the principal site of microbial fermentation. Fore-gut fermenters have an expanded and differentiated fore-stomach. Eutherian fore-gut fermenters include sloths, colobid monkeys, hippos, peccaries, camelids and ruminants. Marsupial fore-gut fermenters include the kangaroos, wallabies and rat-kangaroos. Hind-gut fermenters have ...
متن کاملA ricle Evolutionary Histories of Transposable Elements in the Genome of the Largest Living Marsupial Carnivore, the Tasmanian Devil
The largest living carnivorous marsupial, the Tasmanian devil (Sarcophilus harrisii), is the sole survivor of a lineage originating about 12 Ma. We set out to investigate the spectrum of transposable elements found in the Tasmanian devil genome, the first high-coverage genome of an Australian marsupial. Marsupial genomes have been shown to have the highest amount of transposable elements among ...
