Disruption of the secretion and action of 17,20 beta-dihydroxy-4-pregnen-3-one in response to a rise in temperature in the Arctic charr, Salvelinus alpinus. Consequences on oocyte maturation and ovulation
Plasma levels of 17,20β-dihydroxy-4-pregnen-3-one (17,20βP), and the timing of ovulation were investigated in female Arctic charr (Salvelinus alpinus) reared at 5 °C and at 10 °C during the pre-spawning period. The effects of switching from 5 to 10 °C, and from 10 to 5 °C were also investigated. 17,...

Both LH and 17,20βP stimulated oocyte maturation more effectively in oocytes incubated at 5 °C than at 10 °C. At both incubation temperatures, the rearing temperature of the donor females had a significant impact on their responsiveness to LH stimulation, but had no effect on their responsiveness to 17,20βP stimulation.

The effects of switching from 5 to 10 °C, and from 10 to 5 °C were also investigated. 17,20βP plasma levels were higher at 5 °C than at 10 °C. A switch from 10 to 5 °C stimulated 17,20βP secretion, whereas a switch from 5 to 10 °C had the opposite effect. Ovulation occurred spontaneously in the females kept at 5 °C, and in those switched from 10 to 5 °C. In contrast, ovulation was inhibited in females reared at 10 °C, and in those switched from 5 to 10 °C. Oocyte maturation at 5 °C and at 10 °C in the presence of LH or of 17,20βP was also investigated in vitro using donor females reared at 5 or 10 °C.
