Data represent three independent experiments and were presented as mean ± SEM (n = 10/group). Values with different superscript letters [a (highest value)–d (lowest value)] in the same column were significantly different at p ≤ 0.05. All groups were compared to each other. Cnt, control group; Que, quercetin-treated group; MWC-L, MWCNTs low dose-treated group; MWC-H, MWCNTs high dose-treated group; MWC-L+Que, MWCNTs low-dose and quercetin co-treated group; MWC-H+Que, MWCNTs high-dose and quercetin co-treated group.
