Regulation of mRNA decay by Pumilio in Drosophila melanogaster
… thesis focuses on an RNA-binding protein called Pumilio and its role in regulating the degradation of maternal mRNAs in Drosophila melanogaster embryos. Pumilio protein and pumilio mRNA are both maternally loaded and deficiencies in pumilio are maternal-effect lethal. While homologs of Pumilio …

Pumilio Regulates the Epithelial-Mesenchymal Transition and Gastrulation During Zebrafish Development
The pumilio family of RNA binding proteins act as translational repressors to control developmental patterning events of invertebrates, germline stem cell maintenance, and neuronal growth through deadenylation, inhibition of translational elongation, and allow access of microRNAs to their targets. …

Regulation of Pumilio RNA Binding Proteins by Long Noncoding RNA NORAD
… where it functions by binding to and inhibiting PUMILIO (PUM1 and PUM2) RNA binding proteins (RBPs). Thorough dissection of the functional domains of NORAD establish the essentiality of PUM binding to NORAD for its function in maintaining genome stability. We further examine the mechanism by …

Influence de la protéine Pumilio 2 sur le phénotype sénescent induit par les oncogènes
… induire la sénescence cellulaire. La protéine Pumilio 2 est un membre de la famille des protéines PUF. Ce régulateur post-transcriptionnel se lie aux ARN messagers et inhibe leur traduction ou entraine leur dégradation. Il a été montré que la protéine ERK, dernière kinase de la voie des MAPK, …

¿Cómo varían los ciclos biogeoquímicos debido al aprovechamiento forestal en bosques de Nothofagus pumilio de Tierra del Fuego?
En Tierra del Fuego, los bosques de Nothofagus pumilio (lenga) han sido aprovechados desde principios de la colonización europea. Estos bosques constituyen el principal recurso maderero de interés comercial en el sur de Chile y Argentina. El objetivo general de esta tesis fue evaluar la posible …

Seed predation and potential dispersal of Ceratocaryum argenteum (Restionaceae) nuts by the striped mouse (Rhabdomys pumilio) / Joseph Douglas Mandla White
… were encountered and exploited. Rhabdomys pumilio was confirmed as being the most common murid at the study site, however, it seems unlikely that it scatter-hoards C. argenteum seeds, as no consumption or burial of seeds was observed. However, R. pumilio did show an interest in C. argenteum …

The social organisation and behaviour of the striped field-mouse Rhabdomys Pumilio (Sparrman 1784) : studies in captivity and in the field
… behaviour of the striped field-mouse Rhabdomys pumilio was studied in a large outdoor cage. It was found that the social organisation was based on a male dominance hierarchy, with the development of territory in the dominant male and breeding females. The level of testosterone in males was found …

Demography and population dynamics of the striped fieldmouse, Rhabdomys pumilio, in alien Acacia vegetation on the Cape Flats, Cape Province, South Africa
… small rodent, the striped fieldmouse, Rhabdomys pumilio, over a relatively long period of time. It was felt that the usual field study of one or two years duration was insufficient to obtain reliable data on demographic parameters. This was because it was important to document the variability of …

Ecological Assembly of Leaf-Litter Anuran Communities Across a Neotropical Land-Bridge Archipelago
… in a territorial and common species, Oophaga pumilio, associates with aggressiveness and dominance, and how this association influences the outcome of species interactions; and third, examine species co-occurrence and body size overlap patterns, assessing how differences in coloration - …

An assessment of coping strategies in the marketing of produce by street vendors
… namaquensis, Aethomys ineptus and Rhabdomys pumilio were the most abundant species occurring in almost all altitudinal sites. Six models were built to test influence of different environmental variables on small mammal. Akaike's information criterion (AIC) was used to assess the best model …

Tools for RNA and cell-free synthetic biology
… I report that the RNA-binding protein PumHD (Pumilio homology domain), which has been widely used in native and modified form for targeting RNA, can be engineered to yield a set of four canonical protein modules, each of which targets one RNA base. These modules (which I call Pumby, for …

Biological and ecological studies of Hydrotaea aenescens (Wiedemann) (Diptera: Muscidae), and other arthropods of high-rise cage layer poultry houses
… from the manure samples (including Carcinops pumilio, pseudoscorpions, a dermapteran species, an anthocorid species, and H. aenescens) were correlated with percent manure moisture, the results showed that, of these predators, only H. aenescens was positively correlated with both manure …

The Reproductive biology of Erica pudens
… were found in the faeces of the two Rhabdomys pumilio individuals (average of 13 and 1 respectively). There was very little footage captured of rodent activity around E. pudens flowers and none to demonstrate the foraging activities of a potential pollinator. The exclusion of pollinators showed …

Germline development in Platynereis dumerilii and its connection to embryonic patterning
… role of Nanos (and possibly its partner Pumilio) in the translational repression of hunchback, as it is the case in Drosophila, arguing that this system might be a conserved mechanism to establish embryonic polarity in the protostomes.

Rbfox1 Regulates mRNA Translation to Promote Germ Cell Differentiation
… within their 3’ UTRs. We have identified pumilio (pum) as a critical Rbfox1 target gene. Pum is an RNA-binding protein essential for germline maintenance across species. During germline cyst differentiation, Rbfox1 silences pum mRNA translation thereby promoting germ cell development. …

Intrasexual selection and warning color evolution in an aposematic poison dart frog
… of the strawberry poison frog (Oophaga pumilio) where males are brighter than females, a classic signature of sexual selection. In Chapter 1, I used theoretical models of predator and frog visual systems to determine which can see the variation in bright warning coloration within this …

The natural history, sensory ecology and biogeography of the seed dispersal of large fruits in Fynbos
… by the nonhoarding small mammals, Rhabdomys pumilio and Micaelamys namaquensis. The large, dry, nut-like fruits of Ceratocaryum argenteum have a globally unique, alternative strategy for effective dispersal. The nuts emit a strong scent that mimics the scent of herbivore dung and exploits the …

Are foraging patterns of aerial predators influencing diurnal activity of their prey?
… mainly of the diurnal mouse, Rhabodmys pumilio and a total of 197 hours was spent observing hunting behaviour of four raptor species: Black and African Marsh Harriers (Circus maurus and C. ranivorus), Black-shouldered Kite (Elanus caeruleus) and Rock Kestrel (Falco rupicolus). All birds …

Nucleic Acid Scaffold-dependent Proximity-mediated Enzyme Response (NASPER) - A Proof of Concept Study
