Predicting motif mimicry in viruses
… PPI data can be used to study molecular mimicry in viruses and to discover novel SLiMs. An in-silico peptide exchange approach was developed and applied to provide additional validation of predicted mimicry candidates. Despite limitations of this technique in large-scale validation of …

Targeting Vasculogenic Mimicry in Cancer
… mechanism to angiogenesis known as vascular mimicry (VM). In VM capable tumours, pseudo blood vessels are formed by tumour cells that have acquired endothelial-like properties independently of host endothelium. VM is a marker of poor prognosis and metastasis in patients, however it is still …

Vocal mimicry in the brown thornbill
Mimicry of other species' alarm calls is common among birds, but its function is often unknown. Although anti-predator functions for mimetic alarm calls have been suggested, these are yet to be tested. In this thesis I formally evaluated claims of vocal mimicry in the brown thornbill (Acanthiza …

The evolution of exploitation through mimicry
The aim of this thesis is to propose that mimicry of signals in human communication is an effective behavioural strategy for exploiting social systems. Detection of mimicry may consequently have evolved as a counterstrategy, creating a competitive co-evolutionary relationship between signaller and …

Teaching linguistic mimicry to improve second language pronunciation.
… suprasegementals through the use of linguistic mimicry is more effective than a focus on segmentals in improving native speakers perceptions of accent and comprehensibility of ESL students' pronunciation of English. The thesis is organized into seven chapters. Chapter 2 is a discussion of the …

Biodiversity, conservation and mimicry rings of Appalachian millipedes
… and hue, are shared between genera in aposematic mimicry rings. Leading to the formation of mimicry rings between distantly related genera, their bright coloration functions to advertise a cyanide-based defense. Some species have been recorded as having six color patterns, each a member of a …

Mimicry and speciation in the parasitic finches of Africa
… by critically examining the logic with which mimicry in the natural world can be conceptually organized (Chapter 2). This creates a “mimicry landscape” in which to situate the mimetic adaptations of hosts exhibited by Vidua. The framework can be used to contrast and draw parallels between …

Eukaryotic protein mimicry as an infection strategy for Ehrlichia chaffeensis
… document reports the first example of bacterial mimicry of Wnt pathway ligands and investigates a pathogenic mechanism with potential for targeting by antimicrobial therapeutics.

Prenatal Testosterone, Empathy, Emotion Recognition, and Facial Mimicry in Women
… whether individual differences in facial mimicry, emotion recognition, and empathy are related to prenatal testosterone (PT) exposure. Previous studies have found relationships among facial mimicry, emotion recognition, and selfreport empathy scores; further, imaging studies suggest that …

Molecular characterization of CLE peptide mimicry during cyst nematode pathogenesis
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI-COLUMBIA AT AUTHOR'S REQUEST.] Plant-parasitic cyst nematodes establish intimate parasitic relationships with their hosts by penetrating the root as motile juveniles and migrating intracellularly until they reach the root vasculature where they …

Toward Hydrogenase mimicry : subjecting the problem to three different approaches
In this work, the challenging task of modelling Hydrogenase is subjected to three different approaches. The first strategy used here is bioorganometallic. A wide range of sulfur containing ferrocene-peptide derivatives were synthesized and fully characterized. As a second approach, organic …

Creation of Bioinformatics Approaches to Understand Host-Pathogen Molecular Mimicry
… and proliferation. Also called molecular mimicry, imitation of host biomolecules has been observed to target a wide range of processes, including host signaling pathways and the immune system. Identification of molecular mimicry can provide insights into pathogen virulence and …

Ehrlichia chaffeensis Activates Notch Signaling Through SLiM Mimicry to Inhibit Apoptosis
… the molecular basis of Ehrlichia-Notch ligand mimicry is important for understanding the survival strategies of intracellular pathogenesis. Defining such interactions may lead to the development of novel therapeutics that target host-pathogen protein-protein interactions. The proposed study is …

Host cell-pathogen interactions between erythrocytes and P. falciparum: apoptotic mimicry?
… which could represent a form of apoptotic mimicry; therefore, aiding in parasite perpetuation and immune evasion. A new phagocytic assay was developed, using dihydroethidine and CellTraceTM Violet. While both infected and uninfected erythrocytes in P. falciparum cultures were phagocytosed …
