Transcriptional responses of abalone MTF-1 (a) and MT (b) to experimental heavy metal exposures. Metal exposures were done with cadmium or zinc with the dose strengths of 20 and 100 ppb for 24 h. RT-qPCR data were presented as fold changes of MTF-1 mRNAs in expressed groups relative to that of non-exposed control (Con) based on the normalization against two internal control genes (RPL5 and PPL7). Histograms with different letters indicate the significantly different means based on ANOVA followed by Duncan’s multiple ranged tests at P < 0.05
