Suppression subtractive hybridisation (SSH) was used to generate cDNA libraries representing genes differentially-expressed in liver from male plaice (Pleuronectes platessa) exposed to ethynyl oestradiol (EE2). BLAST analysis and alignments of the clones with database sequence suggested at least three vitellogenin (VTG) genes and three zona radiata protein (ZRP) genes were represented. Clones with unique sequence (62 up-, 13 down-regulated) were arrayed as probes on nylon membranes to investigate temporal expression of oestrogen-responsive genes in experimental animals. Arrays were hybridised with radiolabelled cDNAs prepared from hepatic mRNA from animals treated with EE2 for various times upto 21 days and from treated animals transferred to clean water for upto a further 31 days.
