A comprehensive assessment of peroxisome biology: ER-dependent peroxisome proliferation control, evolution of organelle inheritance in yeast and a Drosophila model system of Zellweger syndromeDownload
The modern eukaryotic cell is a meshwork of encapsulating membranes that compartmentalize many distinct biochemical processes. It is complex. This complexity facilitates the many unique and diverse processes that aid the eukaryote in its growth, division and adaptation to its environment. A...
An ancestral role in de novo peroxisome assembly is retained by the divisional peroxin Pex11 in the yeast Yarrowia lipolyticaDownload
This thesis is on peroxisome evolution and reports my findings with regard to two major aspects of this process. First, I investigated the evolution of a peroxisomal protein family for which large expansions had been noted in diverse eukaryotes from a comparative genomic perspective and combined...
Flaviviruses are important human pathogens that have an enormous impact on global health. Examples that have been studied in my research include dengue virus (DENV), West Nile virus (WNV) and most recently, Zika virus (ZIKV). Currently, there are very few vaccines against or therapeutic...
Expression of PPARα modifies fatty acid effects on insulin secretion in uncoupling protein-2 knockout miceDownload
Aims/hypothesis In uncoupling protein-2 (UCP2) knockout (KO) mice, protection of beta cells from fatty acid exposure is dependent upon transcriptional events mediated by peroxisome proliferator-activated receptor-α (PPARα). Methods PPARα expression was reduced in isolated islets from UCP2KO and...
Peroxisomes are indispensable organelles that perform many essential metabolic activities. Thus, eukaryotic cells have evolved molecular mechanisms to ensure the inheritance of peroxisomes from mother cell to daughter cell at cell division. In the budding yeast Saccharomyces cerevisiae, the class...
Peroxisomes can import large multimeric protein complexes and even 9-nm gold particles decorated with peroxisome-targeting signals. They achieve these feats of protein passage using a distinctive translocon whose highly dynamic aqueous pore can expand to accommodate the increasing girths of...
