Popis: | The ovary of many mammalian species has been shown to produce not only steroids but also a number of regulatory peptides. Some of these peptides, like inhibin (Ying 1988), have extra ovarian functions whereas others, like oxytocin (Wathes and Swann 1982), vasopressin (Clements and Funder 1986), and Vasoactive intestinal peptide (VIP; Gozes and Tsafriri 1986; Ahmed et al. 1986) exert their function within the ovary. Hence, they act in either a para- or autocrine fashion. The messenger RNAs (mRNAs) for some of the above-mentioned peptides have been demonstrated in ovarian extracts in a number of species (Gozes and Tsafriri 1986; Jones and Flint 1988; Fuller et al. 1985; Einspanier et al. 1986). Although species differences exist in the amount of peptides produced by the different ovarian compartments, the fundamental functions of these regulatory peptides appear to be the same. Thus, oxytocin, the best-explored peptide with paracrine action in the ovary, inhibits progesterone release from cultured luteal cells from all species tested so far, including the human (Pitzel et al. 1988). |
