  2. 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

  3. 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

  4. Knowledge Base http://www.wormatlas.org/handbook/fig.s/IntroFIG6.jpg Figure 3 The life cycle of C. elegans

  5. Knowledge Base http://www.vhl.org/gifs/hif-1.jpg Figure 4 The hypoxic response in normal and low oxygen environments

  6. 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 5 Lipofuscin in neurons of the human brain.

  7. Knowledge Base • Exposure to heavy metals induced a higher chance of acquiring PD. (Bjorklund, 1995.) http://img.alibaba.com/photo/103547192/_Super_Deal_Spot_Electrolytic_Copper_Powder_High_Purity_Copper_Powder.jpg Figure 6 Copper oxide

  12. Purpose • The purpose of the experiment is to observe the effects of a hypoxic response in anoxia on the amount of lipofuscin present in C .elegans Hypothesis • Null- the amount of lipofuscin present during the hypoxic response in anoxia will be the same as the amount present without the hypoxic response in anoxia. • Alternate- the amount of lipofuscin present during the hypoxic response in anoxia will be less than the amount present without the hypoxic response in anoxia.

  13. The Effects of the Hypoxic Response in Anoxia on the Amount of Lipofuscin Present in C. elegans Methodology C. elegans obtained from the Caenorhabditis Genetics Center- N=80 Wild type C. elegans: N=40 VHL-1(ok161) C. elegans strain: (vhl-1 deletion) Constitutive HIF-1 in normoxia; slow growth and reduced brood size: N=40 Given copper oxide N=20 Control Wild Type N=20 Given copper oxide N=20 Control VHL-1 N=20 Copper oxide concentrations will be found through experimentation with lethal doses Use of 4',6-diamidino-2-phenylindole (DAPI) to observe the amount of auto fluorescent pigment- lipofuscin- in C. elegans Statistical analysis using SPSS and T-test

  14. 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

  15. 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 + Ampicillin + FUDR + copper oxide  symptoms of Parkinson’s disease starting with the L1 stage  using the DAPI filter to observe amount of lipofuscin present in both C. elegans groups

  17. Protocol Picture by author Figure 15 Process of copper oxide application and observation amongst the four C. elegans groups
