Opioid Peptides Control Progesterone and Estradiol Production in Ovarian Granulosa Cells
Multiple opioid peptides (met-enkephalin, dynorphin, endomorphin) directly inhibited progesterone and stimulated estradiol production in porcine granulosa cells through kappa and mu receptors, revealing complex opioid control of ovarian steroidogenesis.
Quick Facts
What This Study Found
Opioid peptides differentially modulated granulosa cell steroidogenesis: inhibiting progesterone while stimulating estradiol through kappa and mu receptor subtypes, revealing a complex opioid regulatory layer in ovarian hormone production.
