“…For example, rainbow trout, cod, and Atlantic salmon [18,19,48], medaka, Oryzias latipes [49-51], winter flounder, Pseudopleuronectes americanus [52], and gilthead seabream, Sparus aurata [53], synthesize Zr-protein in the liver. Other species, such as carp, Cyprinus carpio [54,55], and pipefish, Syngnathus scovelli [56] appear to synthesize Zr-protein in the ovary. Hence, the primary sequence of Zr-proteins is known in many teleost species, including winter flounder [52], medaka [49,50], carp [54,55], Atlantic salmon [48], and rainbow trout [57-59].…”

Eggshell and egg yolk proteins in fish: hepatic proteins for the next generation: oogenetic, population, and evolutionary implications of endocrine disruption

The oocyte is the starting point for a new generation. Most of the machinery for DNA and protein synthesis needed for the developing embryo is made autonomously by the fertilized oocyte. However, in fish and in many other oviparous vertebrates, the major constituents of the egg, i.e. yolk and eggshell proteins, are synthesized in the liver and transported to the oocyte for uptake. Vitellogenesis, the process of yolk protein (vitellogenin) synthesis, transport, and uptake into the oocyte, and zonagenesis, the synthesis of eggshell zona radiata proteins, their transport and deposition by the maturing oocyte, are important aspects of oogenesis. The many molecular events involved in these processes require tight, coordinated regulation that is under strict endocrine control, with the female sex steroid hormone estradiol-17β in a central role. The ability of many synthetic chemical compounds to mimic this estrogen can lead to unscheduled hepatic synthesis of vitellogenin and zona radiata proteins, with potentially detrimental effects to the adult, the egg, the developing embryo and, hence, to the recruitment to the fish population. This has led to the development of specific and sensitive assays for these proteins in fish, and the application of vitellogenin and zona radiata proteins as informative biomarkers for endocrine disrupting effects of chemicals and effluents using fish as test organisms. The genes encoding these important reproductive proteins are conserved in the animal kingdom and are products of several hundred million years of evolution.

“…All euteleost fish and Clupeiformes, which is diverged early from Otocephala, have both ovarian‐ and liver‐expressing ZP genes (Sano et al., ). The liver‐expressing ZP genes in Otocephala have lost the evolutionary process to Ostariophysi, and the egg envelopes of Ostariophysi, such as milkfish, zebrafish, carp, and goldfish, are composed of ovarian‐synthesized ZP proteins (Chang et al., , ; Sano et al., , ; Wang et al., ). The egg envelopes of euteleost species have been particularly well studied, and their egg envelopes are principally composed of liver‐synthesized ZP proteins (Hamazaki et al., , Murata et al., ).…”

Comparison of Egg Envelope Thickness in Teleosts and its Relationship to the Sites of ZP Protein Synthesis

Teleost egg envelope generally consists of a thin outer layer and a thick inner layer. The inner layer of the Pacific herring egg envelope is further divided into distinct inner layers I and II. In our previous study, we cloned four zona pellucida (ZP) proteins (HgZPBa, HgZPBb, HgZPCa, and HgZPCb) from Pacific herring, two of which (HgZPBa and HgZPCa) were synthesized in the liver and two (HgZPBb and HgZPCb) in the ovary. In this study, we raised antibodies against these four proteins to identify their locations using immunohistochemistry. Our results suggest that inner layer I is constructed primarily of HgZPBa and Ca, whereas inner layer II consists primarily of HgZPBa. HgZPBb and Cb were minor components of the envelope. Therefore, the egg envelope of Pacific herring is primarily composed of liver-synthesized ZP proteins. A comparison of the thickness of the fertilized egg envelopes of 55 species suggested that egg envelopes derived from liver-synthesized ZP proteins tended to be thicker in demersal eggs than those in pelagic eggs, whereas egg envelopes derived from ovarian-synthesized ZP proteins had no such tendency. Our comparison suggests that the prehatching period of an egg with a thick egg envelope is longer than that of an egg with a thin egg envelope. We hypothesized that acquisition of liver-synthesized ZP proteins during evolution conferred the ability to develop a thick egg envelope, which allowed species with demersal eggs to adapt to mechanical stress in the prehatching environment by thickening the egg envelope, while pelagic egg envelopes have remained thin.

“…The molecular composition of invertebrate egg ECMs appears to differ significantly from that of vertebrate egg ECMs. In addition, ZP protein homologues have been identified in several nonmammalian species, including the frog [27][28][29], chicken [30,31], and even fish [32][33][34][35][36], which diverged from mammals 650 million years ago. Instead, invertebrate VEs are composed of completely different proteins, such as VERL in the abalone [22] and the 350-kDa receptor for sperm, VE-B, and other proteins in the sea urchin [23][24][25].…”

Sperm-egg interactions occur at multiple levels on the egg surface, first with the egg's extracellular matrix and then with the egg's plasma membrane. The BioPore minisymposium on "The Egg Surface" at the 1999 annual meeting of the Society for the Study of Reproduction highlighted a series of events underlying successful interactions of the sperm with the egg: 1) composition, synthesis, and assembly of the mouse egg's extracellular matrix, the zona pellucida, during oogenesis; 2) oocyte maturation and development of the sperm-binding domain of mouse eggs; and 3) characterization of functional domains in different sperm ligands (fertilin-alpha and fertilin-beta in the mouse and lysin in the abalone) that recognize cognate binding sites on the egg surface. Data that were presented are reviewed here and discussed with respect to conserved and divergent features of gamete functions.
