Production and impact of prostaglandins on the crab's ovary

Circadian Biology Weekly Brief ↗PubMed ↗DOI ↗

Updated

Abstract

Uptake of labelled arachidonic acid into the ovary of the crab was significantly greater than in other tissues.

  • Prostaglandin H synthase activity increased in the ovary during the late vitellogenic stage compared to immature ovary.
  • Different prostaglandins were biosynthesized in the ovary throughout the crab's reproductive cycle.
  • Injection of prostaglandin F(2alpha) and prostaglandin E(2) led to a significant dose-dependent increase in ovarian index and oocyte diameter.
  • Prostaglandin D(2) did not influence ovarian growth.
