Cryptococcus neoformans, the leading cause of fungal meningitis, is a fungal pathogen that causes severe infection of the central nervous system in patients with compromised immune systems, typically caused by HIV/AIDS. C. neoformans infections are present in developed countries including the United States, but most fatalities occur in sub-Saharan Africa where antiretroviral therapy, the treatment for HIV/AIDS, is less accessible. Current treatments for severe cryptococcal infections are extensive and outdated. There is a critical need for an improved understanding of the fungus and new targeted therapies. Our goal is to identify metabolic pathways important to the survival of C. …

The Role Of Fto, A Human Rna Demethylase In Perennial Grass Development And Abiotic Stress Responses, Andrew Fiorentino, Qian Hu, Xiaotong Chen, Zhaohui Chen
Honors College Theses
The integration of the human fat mass and obesity associated (FTO) gene into turfgrass is a novel approach at improving cell proliferation and abiotic stress resistance. The FTO protein is an RNA demethylase responsible for epigenetic regulation of the genome. In related rice, the gene is associated with increased crop yield, tiller number, and aerial biomass. It is proposed to work via demethylation of repeat RNA associated with chromatin remodeling, causing widespread transcriptional activation. In this study, the feasibility of using FTO for plant trait modification in perennial grasses is being investigated. Potentially transformed embryogenic calli of creeping bentgrass with …

Trypanosoma brucei is a kinetoplastid parasite responsible for human African trypanosomiasis (HAT) and nagana, a livestock wasting disease, which both endemic to sub-Saharan Africa. Unique to kinetoplastids are the specialized peroxisomes, named glycosomes, which compartmentalize the first several steps of glycolysis and gluconeogenesis, nucleotide sugar biosynthesis, and many other metabolic processes. Kinetoplastids are unique in that they have a single mitochondrion. In this work, I present the first study into SET domain proteins in any kinetoplastid parasites. We have characterized a predicted SET domain protein, TbSETD3, that localizes to the mitochondrion and a depletion of the protein results in growth …

Cryptococcus neoformans is an environmental basidiomycetous fungus with a worldwide distribution and a wide range of habitats. Inhalation of the desiccated yeasts or spores of C. neoformans often leads to opportunistic pulmonary infections in immunocompromised individuals, and in severe cases causes lethal meningitis following hematogenous dissemination. During infection, depending on the tissue and disease state, the invading fungi experience a range of nutrient microenvironments within the host body. As a result, rapid metabolic adaptations geared towards efficient utilization of carbon sources alternative to glucose become one of the prime determinants of survival and growth for the pathogen. Incidentally, cryptococcal infection …
