Knowledge Base Parkinson’s disease is a brain disorder involving the nerves. Figure 2 The effects of Parkinson’s disease

Knowledge Base Figure 3 The life cycle of C. elegans

Knowledge Base Lipofuscin is an auto- fluorescent age pigment which is found in people with neurodegenerative diseases. (Gray, et. al., 2005) Figure 4 Lipofuscin in neurons of the human brain.

Knowledge Base Centrophenoxine is an anti-aging medicine which slows the accumulation of lipofuscin. Schneider, et. al. (1977) Figure 5 Molecular structure of centrophenoxine

Literature Review Application of centrophenoxine to the C. elegans decreased the rate of lipofuscin accumulation by an average of 41.3%. (Shulkin, et. al., 1978) Figure 10 Fluorescence of the C. elegans using the lipofuscin as a biomarker for health span. Shulkin, D.J.; B.M. Zuckerman. “Spectrofluorometric analysis of the effect of centrophenoxine on lipofuscin accumulation in the nematode C. elegans.” Age. Volume 5. Pp

Purpose The purpose of the experiment is to observe the effects of centrophenoxine on the restriction of Parkinson’s disease symptoms in C.elegans Hypothesis Null- the symptoms of Parkinson’s disease will remain the same with or without the application of centrophenoxine. Alternate- the symptoms of Parkinson’s disease will lessen with the application of centrophenoxine.

Methodology The Effects of Centrophenoxine on the development of Parkinson’s disease in C. elegans C. elegans obtained from the Caenorhabditis Genetics Center- N=80 Wild type C. elegans: N=40 ham-1(ot339) C. elegans: N= mM centrophenoxine will be applied to the Nematode Growth Media for 21 days. Use of 4',6-diamidino-2-phenylindole (DAPI) to observe the amount of auto fluorescent pigment- lipofuscin- in C. elegans. GFP filter will also be used. Statistical analysis with SPSS Given centrophenoxine N=20 Control N=20 Given centrophenoxine N=20 Control N=20

Protocol C. elegans are grown in petri dishes containing Nematode Growth Media (NGM) from Carolina Biological and fed U.V. killed Escherichia coli. Figure 11 Culturing the C. elegans in Petri dishes Picture by author

Protocol Both Ampicillin and 5-Fluoro-2′-deoxyuridin will be used with NGM in the petri dishes with C. elegans Figure 12 Ampicillin Figure 13 FUDR E.coli + NGM with centrophenoxine + Ampicillin + FUDR  using the DAPI and GFP filter to observe amount of lipofuscin and fluorescence present in both C. elegans groups
