Furthermore, pretreatment with TMP (Figures 5(d), D4; 5(e), E4; 5(f); and 5(g)) or NAC (Figures 5(d), D3; 5(e), E3; 5(f); and 5(g)) significantly decreased the abundance of CCL2 and CCR2 relative to its abundance in the CIN kidneys (p < 0.01). This evidence concerns the gene CCR2 and cervical squamous intraepithelial neoplasia.
