Transcriptional and Biochemical Effects of Cadmium and Manganese on the Defense System of Octopus vulgaris Paralarvae

Figure 2

Expression of hsp70 mRNA in response to cadmium (a) and manganese (b) treatments in the O. vulgaris paralarvae. The expression levels of validated internal control genes (18S rRNA, ubi, and tuba) were used to calculate the normalization factor in real-time PCR experiments. Values indicate the mean ± SD. Asterisks indicate statistically significant differences versus nonexposed controls at .
