The Effect of Centrophenoxine on Parkinson’s Disease Victoria Wei
Need Taken from Rajput AH, Offord KP, Beard CM, Kurland LT. Epidemiology of parkinsonism: incidence, classification, and mortality. Ann Neurol. 1984;16:278-282. Figure 1 The amount of Parkinson’s disease cases per 100,000 people in the United States as age increases
Knowledge Base • Parkinson’s disease is a brain disorder involving the nerves. Figure 2 The effects of Parkinson’s disease http://www.spinstudios.co.uk/sa/pa3.jpg
Knowledge Base http://www.wormatlas.org/handbook/fig.s/IntroFIG6.jpg 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) http://www.innovitaresearch.org/news/res/06042501_01.jpg 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) http://commons.wikimedia.org/wiki/File:Centrophenoxine.svg Figure 5 Molecular structure of centrophenoxine

Driscoll. “In viv spectrofluorimetry reveals endogenous biomarkers that report healthspan and dietary restriction in Caenorhabditis elegans.
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. 50-53. 1982.
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.
The Effects of Centrophenoxine on the development of Parkinson’s disease in C. elegans Methodology Wild type C. elegans and ham-1 (ot339) C. elegans obtained from the Caenorhabditis Genetics Center N=80 Wild type C. elegans: N=40 ham-1(ot339) C. elegans: N=40 Given 6.8 mMcentrophenoxine N=20 Control N=20 Given 6.8 mMcentrophenoxine N=20 Control N=20 6.8 mMcentrophenoxine 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 filters may also be used to observe whether the C. elegans DA neurons will be affected by the application of centrophenoxine Statistical analysis
Protocol • C. elegans are grown in petri dishes containing Nematode Growth Media (NGM) from Carolina Biological and fed U.V. killed Escherichia coli. Picture by author Figure 11 Culturing the C. elegans in Petri dishes
Protocol • Both Ampicillin and 5-Fluoro-2′-deoxyuridin will be used with NGM in the petri dishes with C. elegans http://upload.wikimedia.org/wikipedia/commons/b/b6/Ampicillin_structure.svg Figure 13 FUDR Figure 12 Ampicillin http://www.sigmaaldrich.com/structureimages/30/mfcd00006530.gif 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
