Abstract

Obesity is common in the Appalachain population and contributes of disorders of metabolism of lipid called, collectively, dylipidemias. These are primarily the result of consuming western diet, which contains high amounts of fats and cholesterol. The goal of our study is to determine the effects of diet induced oxidative stress on larval zebrafish (Danio rerio). Our first hypothesis is when larval zebrafish are fed a high-fat diet, oxidative stress will be induced. Our second hypothesis is that when a high-fat diet is combined with the natural product Dihydronortanshinone (DNT), there should be a reduced amount of oxidative stress. To test these claims, we will have three dietary conditions for the zebrafish, a low-fat diet, a high-fat diet, and a high-fat diet plus DNT. Zebrafish will be fed for eight weeks, and their food consumption will be calculated after each feed. After eight weeks, the body fat volume will be calculated, and a dissection of the intestines will occur. The dissected intestines will be processed for RNA extraction and RT-PCR of oxidative stress genes. We expect to see increased BMI in the high-fat diet animals. In the high-fat diet plus DNT aimals we expect to see a decrease in oxidative strees response gene expression. This study's significance is to fill in knowledge gaps associated with oxidative stress created by high-fat diet consumption.
