Fumigant Activity of the Psidium guajava Var. Pomifera (Myrtaceae) Essential Oil in Drosophila melanogaster by Means of Oxidative Stress

Figure 3

Analysis of the Nrf2/NQO-1/HSP70 signaling pathway in D. melanogaster exposed to P. guajava var. pomifera essential oil. After treatments were finished, samples were collected at each time point indicated and processed for western blot evaluation of each protein target. (a) Representative immunoblots for protein targets at 3 h of exposure to the essential oil. (b) Representative immunoblots for protein targets at 6 h and 12 h of exposure to the essential oil. (c) Optical densitometry of immunoreactive bands of NQO-1. Results are expressed as arbitrary units (mean ± SD). compared to control.
