Responses To Fine Particulate Matter (Pm2.5) Exposures In Two Wild-Type Zebrafish Strains, Connor Necaise
Honors Theses
Atmospheric fine particulate matter (PM2.5) exposure poses great health risks across the globe, causing both acute and chronic illnesses in humans. Therefore, a more complete understanding of the mechanisms in which PM2.5 induces these adverse health effects is urgently needed. Oxidative stress due to PAHs and other common components of PM2.5 is a proposed mechanism for its adverse health effects. However, little is known about the actual mechanisms of PM2.5 damage in humans. This study aimed to distinguish behavioral differences in two lines of zebrafish (AB & 5D) as a result of developmental exposure to …

I tested the hypothesis that recombinant leptin protein can be introduced to zebrafish in vivo through non-invasive soaking in a solution containing the protein. One way to study various molecules’ effects in vivo is through intraperitoneal or intracerebroventricular injections during the embryonic or larval stage, which is invasive, difficult to administer, and can have a high mortality rate. 48 hours post fertilization (hpf) zebrafish were soaked in a His-tagged recombinant leptin protein solution at 10 nM and 100 nM concentrations (produced by Genscript). After soaking, zebrafish larvae were washed extensively to remove all recombinant protein on their exterior before homogenization. …
