Knowledge BaseLipofuscin 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. http://www.innovitaresearch.org/news/res/06042501_01.jpg
Knowledge BaseCentrophenoxine is an
anti-aging medicine which slows the accumulation of lipofuscin.

Literature ReviewApplication of centrophenoxine to the C. elegans
decreased the rate of lipofuscin accumulation by an average of 41.3%. (Shulkin, et. al., 1978)

PurposeThe purpose of the experiment is to observe the effects
of centrophenoxine on the restriction of Parkinson’s disease symptoms in C .elegans
HypothesisNull- 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
C. elegans obtained from the Caenorhabditis Genetics Center- N=80
Wild type C. elegans: N=40 ham-1(ot339) C. elegans: N=40
6.8 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 centrophenoxineN=20
Control N=20
Given centrophenoxineN=20
Control N=20
ProtocolC. elegans are grown
in petri dishes containing Nematode Growth Media (NGM) from Carolina Biological and fed U.V. killed Escherichia coli.
