We found that the Octopus ER is widely expressed in both
sexes, with the highest transcript levels in ovary. These results
are consistent with a role in female reproduction but do not rule
out other functions as well. Our experiments were limited to a
single time point. Further studies are necessary to determine
whether ER expression is temporally up-regulated in some
tissues during specific stages of the Octopus reproductive cycle.
