Knowledge BaseLipofuscin is an auto-

fluorescent age pigment which is found in people with neurodegenerative diseases. (Gray, et. al., 2005)

Figure 10 Mutation of VHL-1 reduces accumulation of auto-fluorescent age pigments

PurposeThe purpose of the experiment is to observe the effects

of a hypoxic response in anoxia on the amount of lipofuscin present in C .elegans

HypothesisNull- 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.

The Effects of the Hypoxic Response in Anoxia on the Amount of Lipofuscin Present in C. elegans

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

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

Given copper oxideN=20

Control VHL-1N=20

Given copper oxideN=20

Control Wild TypeN=20

ProtocolC. elegans are grown

in petri dishes containing Nematode Growth Media (NGM) from Carolina Biological and fed U.V. killed Escherichia coli.

ProtocolBoth Ampicillin and 5-Fluoro-2 -deoxyuridin will be ′

used with NGM in the petri dishes with C. elegans
