Abstract: | Indolylalkylamines (5-HT, 5-chlorotryptamine, 5-ethyltryptamine) suppress or block the progesterone-induced oocyte maturation in Bufo viridis and Xenopus laevis and disturb cytoskeletal rearrangements associated with oocytes involved, together with the other transmitter systems, in modulation of progesterone effect. |
