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.
