Effects of Starvation on the Levels of Triglycerides, Diacylglycerol, and Activity of Lipase in Male and Female Drosophila Melanogaster

Figure 2

Levels of TG and DG in 2 d old male and female flies during starvation. Lipids were separated on thin layer chromatography at different time periods after the male and female flies were subjected to starvation (a). The density of the TG spots (b) and DG spots (c) (percent of control) as a function of starvation time was measured. Levels of TG in both male and female flies decreased depending upon the duration of starvation. There was a significant increase in levels of DG in final phase of starvation (48-57 h) in female flies (c). In male flies, DG levels continued to increase after death from 48 to 57 h (all 10 male flies were dead at 48 h of starvation) (c). The percent of DG levels vs. percent of dead male and female flies at different starvation period is shown in (d). The data is representative of three experiments and is presented as the . It was analyzed by two-way ANOVA with Sidak’s multiple comparison test. denotes , denotes , denotes , and denotes .
