daf-7 expression declines in aging animals. A) Expression pattern of ksIs2[
daf-7p::GFP] reporter in young (i,ii) and aged (iii,iv)animals. Solid triangles indicate ASI neurons, open triangles indicate ASJ neurons. B) Quantification of GFP expression driven by ksIs2[
daf-7p::GFP], normalized to exposure time. Representative of 4 replicates with n>10 animals per day. *** represents p < 0.001 by one-way ANOVA C)Quantification of GFP expression driven by cuIs5[C183::
myo-2p::GFP] in aging animals, normalized to exposure time. WT statistics indicated ongraph,
daf-7(
e1372) statistics- Day 3 p = 0.0002; Day 5 p = 0.5225; Day 7 p = 0.0005; Day 9 p = 0.0445; all differences in
daf-7(
e1372) are aresult of increased GFP fluorescence later in life. Representative of 4 replicates with n>10 animals per genotype per day. *** representsp < 0.001 by one-way ANOVA D) Summary of lifespan experiments initiating BD at various times in adulthood. * indicates BD lifespan wassignificantly different (p < 0.005) than fed control group in all experiments.
