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.

Methodology 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 2 hour timed egg laying for C. elegans. During the L4 stage, the C. elegans will be transferred to the Nematode Growth Media *(NGM) at 20°C. The C. elegans are fed U.V. killed E. coli stored at room temperature and grown overnight at 37°C. C. elegans are grown in liquid media at 16°C. 1.5 mM of 1-methyl-4-phenylpyridinium (MPP+) after the L1 stage is applied in the food. Use of 4',6-diamidino-2-phenylindole (DAPI) to observe the amount of auto fluorescent pigment- lipofuscin- in C. elegans- scale will be used to measure the amounts of lipofuscin. Statistical analysis using SPSS and T-test Given MPP+ N=20 Control VHL-1 N=20 Given MPP+ N=20 Control Wild Type N=20

Protocol C. elegans are grown in petri dishes containing Nematode Growth Media (NGM) from Carolina Biological and fed U.V. killed Escherichia coli. Figure 10 Culturing the C. elegans in Petri dishes Picture by author
