Effects of 20 nm PVP-AgNPs and MT on ROS (A) and the relative fluorescence intensity of ROS (B) in C. elegans after 48 h exposure (10×). The influence of the expression of mRNA of mtl-1 and mtl-2 induced by 20 nm PVP-AgNPs in C. elegans (C). Effects of 20 nm PVP-AgNPs in the expression of fluorescence of mtl-1 (D, E) in CF2222 nematode strain (mtl-1::RFP) after 48 h exposure (20×). Effects of 20 nm PVP-AgNPs in the expression of fluorescence of mtl-2 (F, G) in CL2120 nematode strain (mtl-2::GFP) after 48 h exposure (20×). Experimental data were represented by mean ± SD in three parallel experiments. Compared with the control group, *P < 0.05. AgNPs, silver nanoparticles; PVP, polyvinylpyrrolidone; HPMC, hydroxypropyl methyl cellulose.
