SM increased lipofuscin accumulation in let-60 (gf) mutants.
(A) Fluorescence image of worms after SM treatment for 5 days (N = 20). Con and C: control. Scale bar, 200 μm. (B) Quantified fluorescence intensity of lipofuscin. Data is presented as the mean ± SD of at least three independent experiments. Bars with different letters indicated that there was a significant difference at a level of 0.05 among groups.
