a–c Relative mRNA level of the three putative PGES genes in control and LsHPX1 KD animals. Expression was calculated relative to 18S expression, and the average mRNA level ± SD is shown (N = 3). Arrows indicate the approximate time of molting from nauplius 2 to copepodids. d Analysis of PGE2 metabolites. e PGF2α metabolites in control and KD animals at 8 days post-hatching (dph). Average metabolite amount ± SD is given (N = 3). Asterisks indicate statistical difference between control and KD animals, determined by t-tests with a threshold P value of 0.05
