Ng that Se(IV) can counteract the toxicity induced by Pb(II). Similarly, without the supplementation of 0.01 mM of Se(IV), a substantial lower in head thrash occurred in worms exposed to 100 mM of Pb(II), in comparison with these handle (P,0.001) (Fig. 2B). Nematodes with Se(IV) pretreatment exhibited considerable protection (P,0.001) against Pb(II)-induced toxicity on head thrash (Fig. 2B). Despite the fact that Se(IV) pretreatment cannot totally guard the head thrash behavior against Pb(II) neurotoxicity, as observedPLOS A single | plosone.orgFigure 1. Se(IV) attenuated the declines of locomotion behaviors in aged C. elegans. Synchronized wild-type L1 larvae were incubated with various concentrations of Se(IV) (0.01, 0.05, and 0.1 mM) or distilled water as the solvent control at 20uC.

Synchronized L1 wild-type larvae had been incubated with 0.01 mM of Se(IV) or distilled water as the solvent manage for 40 h at 20uC. Subsequently, Se(IV)-pretreated and manage young adult worms were divided into two aliquots and treated with or without the need of 100 mM of Pb(II) for 24 h at 20uC. (A) The amount of physique bends in 20 s, (B) the number of head thrashes in 1 min, and (C) the reversal frequency in 3 min. Approximately thirty worms from each remedy at each time point had been randomly selected for scoring.

A considerable boost in reversal frequency was observed in worms exposed to 0.01 mM of Se(IV), compared to those devoid of Se(IV) manage (P,0.001) (Fig. 2C), suggesting that Se(IV) has ameliorative impact on reversal frequency to C. elegans. Taken together, pretreatment of 0.01 mM of Se(IV) can protect the locomotion behaviors of C. elegans against Pb(II)-induced harm.Se(IV) Decreases the Intracellular ROS Level in C. eleganThis sections explores a mechanism that may explain the manner in which Se(IV) suppresses the decline of locomotion behaviors induced by Pb(II). Pb(II) exposure causes substantial oxidative damage and production of reactive oxygen species (ROS) in C. e.
