PhD Oral Defense ofÌýVahid H Gazestani,ÌýInstitute of Parasitology
Trypanosomatid pathogens, causative agents of serious diseases in humans and animals, areÌývector-borne parasites with intricate life cycle. These pathogens rely on fine regulation of ÌýgeneÌýexpression to respond and adapt to variable environments, with implications in transmission andÌýinfectivity. Unlike mammals (hosts) or most other eukaryotes, trypanosomatid gene regulationÌýoccurs at the post-transcriptional level mostly through interaction of trans-acting RNA-bindingÌýproteins (RBPs) and cognate cis-acting sequence elements (¬RNA Regulatory Elements, RREs)Ìýthat direct mRNA maturation, localization, stability, and translation rate. However, theseÌýregulatory elements and their mechanisms of actions are largely unknown. In this thesis, we useÌýintegrated computational experimental strategies to unravel the regulatory circuitsÌýcontrolling RNA processing and abundance in these human parasites that can be eventuallyÌýexploited to identify novel chemotherapeutics.
