Intra-oviductal administration of RNA obtained from oviducts of estradiol-treated rats resulted in accelerated egg transport (<A HREF="#rios97">Ríos et al., 1997</A>). It is probable that estradiol-induced messenger RNA (mRNA) entered oviductal cells and was translated into the proteins involved in accelerated egg transport. In order to test this interpretation we deposited in vivo 50 µg of pure ß-galactosidase (ß-gal) mRNA, 50 µg of pure DNA from the reporter gene ß-gal under SV40 promoter or the vehicle (control oviducts) into the oviductal lumen of rats. Twenty four hours later the ß-gal activity was assayed in oviductal tissue homogenates using o-nitrophenyl-ß-D-galactopyranoside as a substrate. The administration of ß-gal mRNA and pSVBgal... |
