Ascorbic acid (Vitamin C) is an excellent water-soluble dietary antioxidant, well known to protect the biomolecules from oxidative stress-linked damages. It is reported to show a contrary behavior by inflicting pro-oxidant effects under varied, altered circumstances. The present work is an attempt to study the antioxidant and pro-oxidant behavior of ascorbic acid in Musca domestica larvae. Its pro-oxidant properties were tested by exposing the larvae to various concentrations of ascorbic acid. For confirming its oxidant scavenging properties, its effects on the antioxidant enzyme profiles were studied in both the normal and stress-induced M. domestica larvae. Oxidative stress was induced by adding D-Galactose (D-Gal) to the normal food supplement of the larvae. Outcomes of the study demonstrate that ascorbic acid acts as an efficient antioxidant when added in lower concentrations, but at high concentrations, it induces oxidative stress in the larvae, thus acting as a pro-oxidant. At the concentration of 10 mM, ascorbic acid significantly reduced the oxidative stress induced by D-Gal (p < 0.05) and maintained the percent pupal survival and percent eclosion. In conclusion, we suggest that ascorbic acid may function as an antioxidant and pro-oxidant in a concentration-dependent manner under normal physiological conditions.

The usage of insects as a sustainable and functional natural products resource is a new promise in complementary and alternative medicine. The present study aimed to investigate the ability of Musca domestica (housefly) larval hemolymph (insect blood) to display the enhanced in vitro antioxidant and cytotoxic effects. The oxidative stress (OS) was elicited by inducing lipopolysaccharides (LPS) treatment as an exogenous stressor. Determination of superoxide dismutase 1 (SOD1), glutathione (GSH), malondialdehyde (MDA) and total antioxidant capacity (TAC), and mRNA and protein expressions of SOD1, was investigated as confirmatory markers of oxidative stress induction. Cytotoxicity on cancerous MCF-7 and normal Vero cells were also evaluated using an MTT assay at 24 h post-injection. The injection of LPS induced a significant (p < 0.05) increase in SOD, GSH and TAC, whereas, the MDA was diminished. Hemolymph was collected from normal and treated larvae after 6, 12 and 24 h. The M. domestica superoxide dismutase (MdSOD1) transcripts were significantly (p < 0.05) upregulated 6 and 12 h post-treatment, while a significant downregulation was observed after 24 h. Western blot analysis showed that MdSOD1 was expressed in the hemolymph of the treated larvae with an increase of 1.2 folds at 6 and 12 h and 1.6 folds at 24 h relative to the control group. LPS-treated larval hemolymphs exhibited significant cytotoxicity with respect to the untreated ones against MCF-7 while Vero cells showed no cytotoxicity for both hemolymphs. The DPPH free radical scavenging activity was examined and a significant antioxidant potential potency was observed at 6 h (50% maximal inhibitory concentration (IC50): 63.3 ± 3.51 µg/mL) when compared to the control M. domestica larval hemolymph (IC50: 611.7 ± 10.41 µg/mL). Taken together, M. domestica larval hemolymph exhibited enhanced antioxidant and consequently increased cytotoxic capacities under stressed conditions.
