In contrast, the basal gene expression of MT-1H, MT-1F, MT-1E, MT-1G was a little transcript in HPBLs. No signal was detected for the MT-1B. There was a sex difference (P < 0.05) in basal gene expression of MT-1E. The level of gene expression of MT-1A, MT-1E, MT-1F, MT-1G, MT-1H and MT-1X was significantly increased (P < 0.05), but not the level of MT-1B after exposure to cadmium.It was suggested that gene expression of MT-1F, MT-1G, MT-1H and 1X in HPBLs could be used as potential exposure biomarker.Read More
