Excess Fructose In High-Fructose Corn Syrup Reduces Cell Viability & Promotes Nitric Oxide Release In Raw 264.7 Macrophages, Renzo F. Galarza, Edward L. Villegas
Research and Creativity Symposium
High-fructose corn syrup (HFCS) is an artificial sweetener that contains slightly higher concentrations of fructose compared to standard sucrose. It has been linked to an increased risk of obesity, type 2 diabetes, cardiovascular disease, and fatty liver disease. While both HFCS and sucrose are widely used sweeteners, growing evidence suggests they may differ in their inflammatory potential. We sought to understand the effects of elevated fructose on RAW 264.7 macrophages. To investigate these effects, we treated the cells with either a sucrose solution or a
solution designed to mimic high-fructose corn syrup. Lipopolysaccharide (LPS) stimulation was used to model innate …

Departmental Honors & Graduate Capstone Projects
Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer with treatment limited to chemotherapy. However, not all patient tumors respond to chemotherapy. The variable cytotoxic effects of chemotherapies may be due to how cancer cells regulate reactive oxygen species (ROS). In this study, we examined two mouse breast cancer cell lines: 4T1 and EO771, vary when treated with hydrogen peroxide (H2O2) and 5-Fluorouracil (5FU), known ROS-inducing substances. In 4T1 cells H2O2 increased oxidized DNA but caused minimal cell death. While in EO771 cells that same amount of H2O2 caused complete apoptosis. Cell number, ROS, and cell death showed …
