Figure 6

(A) Expression of Cu/Zn-SOD3 (CSD3) in P. dicentrarchi trophonts exposed to different levels of UV radiation, as determined in a Western blot (WB) assay with a polyclonal antibody against the recombinant protein rCSD3 (anti-rCSD3) and proteins in peak 2 (P2) purified by ion exchange chromatography. The graph corresponds to the densitometric analysis of the WB (n = 3). A representative WB (not cropped) is shown in the figure. (B) Expression of Cu/Zn-SOD3 transcripts by ciliates exposed to different doses of UV radiation and quantified by RT-qPCR. (C) SOD activity in the P2 fraction from ciliates treated by UV irradiation (3 J/cm2) and untreated ciliates (control), as determined by the PMS-NBT (phenazine methosulfonate - nitroblue tetrazolium) assay. The enzymatic activity was quantified as the decrease in absorbance at 560 nm/min (−Δabsorbance/min). The mean values and standard error are represented in the bar graph, and the asterisks indicate statistically significant differences (*P < 0.05; **P < 0.01) relative to the non-irradiated control.
