Arsenic is a metalloid that contaminates drinking water supplies worldwide. Due to concerns for human health, the World Health Organization (WHO) and the U.S. Environmental Protection Agency (EPA) have established a safe level in drinking water of ≤ 10 ppb. Arsenic has been shown to have carcinogenic effects in humans at high and low doses. Chronic exposure may result in dermal conditions such as hyperkeratosis and hyperpigmentation. Recently, arsenic exposure has also been linked to lower IQ values in children. The effect of arsenic on neurogenesis, specifically eye development, has not been widely explored. This study aimed to examine the …

Evolutionary And Molecular Analysis Of Conserved Vertebrate Immunity To Fungi, Erin Carter

The innate immune system is highly conserved amongst all multicellular organisms. Yet a constant battle exists between host cells and pathogens due to the rapid evolution of immune system components. Functional genomics and in silico methods can be employed to elucidate the evolutionary patterns of vertebrate immunity to pathogenic fungi such as Candida albicans, an opportunistic fungal pathogen that can cause lethal candidiasis in the immunocompromised. Mammals such as humans and mice possess conserved C-type lectin receptors that recognize the C. albicans cell wall. However, these receptors have not been identified in fish. Here I describe how we identified potential …

Recently, the Kim Lab has shown that the cystic fibrosis transmembrane conductance regulator (cftr) gene is responsible for mediating resistance to Pseudomonas aeruginosa in a zebrafish infection model. Using the Gene Expression Omnibus, an NCBI functional genomics data repository, it was determined that Smad3, a transcription factor in the TGF-β signaling pathway, is upregulated in the presence of P. aeruginosa. It was found that in our zebrafish model, the Smad3 paralogs Smad3a and Smad3b are upregulated following microinjection of a cftr antisense morpholino oligomer. It was also found that microinjection of Smad3a and Smad3b morpholinos, along with …
