  9. Literature Review • Nass, et. al., (2002) • GFP is a usable method of observing the dopamine neurons in C. elegans. Dopamine neurons are unaffected Dopamine neurons are progressively dying Figure 10 Degeneration of dopamine neurons http://docs.google.com/gview?a=v&q=cache%3AtdtxA_lhng0J%3Aweb.mac.com%2Frdblakely%2FBlakelyLab%2FBlakely_Lab_News_files%2FWorm%2520research%2520yields%2520powerful%2520model%2520for%2520Parkinson%27s%2520disease%25203.1.02.pdf+c+elegans+parkinson%27s+filetype%3Apdf&hl=en&gl=us

  10. 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 Table displaying effect of centrophenoxine on lipofuscin in C. elegans 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.

  11. Purpose • The purpose of the experiment is to observe the effects of centrophenoxine on Parkinson’s disease 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.

  12. The Effects of Centrophenoxineon Parkinson’s disease in Caenorhabditiselegans Methodology Caenorhabditis elegansham-1(ot339) obtained from the Caenorhabditis Genetics Center (CGC) N=100 Given 6.8 mMcentrophenoxine: N=50 No centrophenoxine is applied: N=50 C. elegans will be cultured in the Nematode Growth Media at 20 °C , and fed Escherichia coli(op50). 6.8 mMcentrophenoxine will be applied to the NGM where the C. elegans are cultured and observed throughout lifespan. Qualitative data will be collected on how strong both the GFP and lipofuscin fluorescence is-using a scale that ranges the strength of fluorescence. Statistical analysis with SPSS

  13. Protocol • C. elegans are grown in petri dishes at 20°C with NGM and fed U.V. killed E. coli. • Both Ampicillin and 5-Fluoro-2′-deoxyuridin (FUDR) are added to the plates Picture by author Figure 11 Culturing the C. elegans in a petri dish

  14. Protocol E.coli + NGM with centrophenoxine + Amp + FUDR using the DAPI and GFP filter to observe amount of lipofuscin and GFP fluorescence present in both C. elegans ham-1(ot339)groups
