compared with uninfected controls (naive, DSF-only, TTM-only), PbA infection-induced ECM controls (Pb group) exhibited upregulated expression of SLC31A1 (P < 0.01), FDX1 (P < 0.01), DLAT (P < 0.01), and DLST (P < 0.01), alongside downregulated ATP7A (P < 0.01). This evidence concerns the gene ATP7A and infection.
