Evaluating Selected Antioxidants on UV Light Induced Stress in Lumbriculus Variegatus

Overview

Many diseases such as skin cancer, retinoblastoma, and macular degeneration are linked to free radical damage from UV light. Antioxidants are molecules that contain an extra electron that they give up to free radicals to stop the damage they cause to cells. Changes in the environment due to the increase in air pollutants, poor diets, and the depletion of the ozone layer allowing more UV light to reach earth all contribute to induced cellular stress. The purpose of this investigation is to evaluate how a diet with a high amount of antioxidants can protect against free radical damage to cells. Ii is hypothesized that the selected antioxidants would increase the amount of segments that regenerate in UV light stressed worms. 120 worms were split into 24 groups of 5 worms each for the experimental and control groups. Several tests were conducted to support or reject each of the hypotheses. The data suggests the main hypothesis was supported and the evaluated antioxidant foods were able to increase cell regeneration in each of the UV light induced stressed L variegatus experimental groups.
