Replacement of the famesyl group by lipid analogues could be performed for full length Ras proteins in vitro by means of the enzyme famesyltrans-ferase. When such partially modified Ras constructs were applied in Xenopus oocytes the cellular machinery completed modification (endoprotease activity, carboxymethylation and palmitoylation). In these cases the H-Ras famesyl group could be stripped off most of its isoprenoid features that distinguish it from a fatty add without any apparent effect on its ability to induce oocyte maturation and activation of mitogen-activated protdn kinase In contrast, replacement by the less hydrophobic isoprenoid geranyl causes severely delayed oocyte activation. 

There is ever more evidence that the results obtained with low doses can equal those earlier obtained with larger doses, while in principle reducing the risk of over-stimulation. Where human chorionic gonadotropin is concerned, a dose of 3300 IU now appears to be sufficient, at least in high responders, to provide adequate oocyte maturation and fertilization (29), whereas doses of 5000 or 10 000 U have often been used. 

The sexual dimorphism of cuticular hydrocarbons is completed during the first three days after imaginal eclosion. During the same period, important physiological events take place, female oocyte maturation and vitellogenesis. A number of mutations have been described which affect ovarian development or endocrine control. These mutants were used to elucidate a possible hormone control mechanism used to regulate hydrocarbon biosynthesis.

It is now apparent that teleost vitellogenesis involves a suite of distinct Vgs and product yolk proteins with specific functions during oocyte maturation and development of embryos and larvae. Thus vitellogenesis is a far more complicated and interesting process than was previously thought. These complications in the...

A LOCAL REGULATOR OF OVULATION, OOCYTE MATURATION, AND LUTEAL FUNCTION... 

While several functions for NO have been identified, the signal transduction pathway(s) that are utilized by NO at critical stages of ovarian development have not yet been definitively elucidated. The ecNOS- and iNOS-deficient mice provide excellent tools for the dissection of the relative functions for each isoform in the ovary. Furthermore, the study of ovarian NOS provides an experimental system in which the roles of ecNOS and iNOS in development (follicular and oocyte maturation) and differentiation (formation of the corpus luteum) can be studied. 

Volume 5 of Advances in Developmental Biochemistry consists of seven chapters that review specific aspects of development in several different organisms including mollusks, flies, and mice. Five of the seven chapters address aspects of fertilization, including capacitation of sperm (Chapter 3), the acrosome reaction (Chapter 7), gamete adhesion (Chapters 2 and 6), and oocyte maturation and ovulation (Chapter 4). 

In Chapter 4, Olson discusses ovarian nitric oxide, a local regulator of ovulation, oocyte maturation, and luteal function in mammals. Although this is a relatively new area of investigation, there is compelling evidence that nitric oxide is a local regulator of all of these key ovarian processes in mammals. The author provides an experimental basis for this conclusion and for future studies.
