Abstract
Gangliosides have been suggested to play important roles in various functions such as adhesion, cell differentiation, growth control, and signaling. Mouse follicular development, ovulation, and luteinization during the estrous cycle are regulated by several hormones and cell-cell interactions. In addition, spermatogenesis in seminiferous tubules of adult testes is also regulated by several hormones, including follicle-stimulating hormone (FSH) and luteinizing hormone (LH) and cell-cell interactions. The regulation of these processes by hormones and cell-cell interactions provides evidence for the importance of surface membrane components, including gangliosides. During preimplantation embryo development, a mammalian embryo undergoes a series of cleavage divisions whereby a zygote is converted into a blastocyst that is sufficiently competent to be implanted in the ma ternal uterus and continue its development. Mouse embryonic stem (mES) cells are pluripotent cells derived from mouse embryo, specifically, from the inner cell mass of blastocysts. Differentiated neuronal cells are derived from mES cells through the formation of embryonic bodies (EBs). EBs recapitulate many aspects of lineage-specific differentiation and temporal and spatial gene expression patterns during early embryogenesis. Previous studies on ganglioside expression during mouse embryonic development (including during in vitro fertilization, ovulation, spermatogenesis, and embryogenesis) reported that gangliosides were expressed in both undifferentiated and differentiated (or differentiating) mES cells. In this review, we summarize some of the advances in our understanding of the functional roles of gangliosides during the stages of mouse embryonic development, including ovulation, spermatogenesis, and embryogenesis, focusing on undifferentiated and differentiated mES cells (neuronal cells).

Abstract
The 350-kDa sperm-binding protein (SBP), a species-specific sperm-binding protein, is localized in the vitelline layer of sea urchin eggs. In this study, we have shown for the first time that sperm gangliosides are ligands for the intact glycosylated SBP. Using recombinant fragments of the SBP, the N-terminal heat shock protein 110-like domain was shown to be responsible for the binding. The intact SBP could bind various gangliosides, and the binding was sialidase-sensitive and inhibited by sialyllactose, thus indicating that it is the sialic acid-binding protein. Calcium and magnesium ions were not required but they did enhance the binding activity of SBP. The observation that bacterially expressed recombinant SBP and the sialidase-treated intact glycosylated SBP lost divalent cation-dependent enhancement of binding activity suggests that the sialylated carbohydrate moieties of the SBP may be involved in this property. Furthermore, the SBP was shown to bind sperm lipid rafts, in which gangliosides are enriched, and this binding was lost upon sialidase treatment of the lipid rafts. Finally, liposomes containing the ganglioside specifically inhibited fertilization. Taken together, these results allow us to identify SBP as a member of a new class of sialic acid-binding lectin belonging to the Hsp110 family, and indicate that SBP may be involved in interaction of sperm with the vitelline layer of the egg.

Abstract
Diabetes and obesity cause abnormal development of reproductive processes in a variety of species, but the mechanisms that underlie this effect have not been fully elucidated. This study examined the expressional changes of ganglioside GM3 during ovarian maturation, in vitro fertilization (IVF) and early embryonic development in diabetic/obese db/db mice. In high-performance thin-layer chromatography studies, GM3 expression was conspicuously low in the ovaries of db/db mice compared to non-diabetic db/+ mice. Signal detected by anti-GM3 monoclonal antibody was greatly reduced in the primary, secondary and graffian follicles of db/db mice compared to control mice. Results from IVF with ova and sperm from db/db mice showed that GM3 expression during early embryonic development was obviously decreased compared to db/+ mice. This study also elucidated the effects of high glucose (20 and 30 mm) on early embryonic development in ICR strain mice. High glucose caused a decrease in GM3 expression during early embryonic development. Taken together, the results of this study indicate decreased GM3 expression during ovarian maturation and embryonic development of db/db mice, suggesting that alteration of ganglioside expression induced by the diabetic condition may be implicated in the abnormal follicular embryonic development.

Abstract
The low density detergent-insoluble membrane (LD-DIM) fraction was obtained by a sucrose-density gradient centrifugation from sperm of three sea urchin species, Hemicentrotus pulcherrimus, Strongylocentrotus purpuratus, and Anthocidaris crassispina. These LD-DIM preparations were characterized by enriched glycosphingolipids (GSL) including gangliosides and sulfatide (SLF), having more than 50% of the total amount of GSL present in these sperm. Interestingly, a minor component of H. pulcherrimus sperm (HO3S-->8Neu5Acalpha2-->8Neu5Acalpha2-->6Glcbeta1++ +-->Cer) was shown to be even more enriched in the LD-DIM as revealed by using monoclonal antibody (mAb.3G9) speific to this ganglioside. In addition to the GSL, phosphatidyl-serine (PS) and diacylglcerol (DG) were enriched in the LD-DIM. On the other hand, cholesterol (CL) and sphingomyelin (SM) were not so enriched, which contrasted with the LD-DIM from Madin-Darby canine kidney (MDCK) cells, where CL and SM were reported to be abundant. Because mammalian somatic cell-derived DIMs have been proposed to be associated with functional signal transduction, it seems possible that the ganglioside-enriched LD-DIM in sea urchin sperm can participate in binding to eggs and the subsequent egg activation process. To our knowledge this is the chemical characterization of the LD-DIM fraction of a gametic cell.

Abstract
M5 ganglioside (NeuGc alpha 2-6Glc beta 1-1'Cer) is the predominant glycosphingolipid in sea urchin eggs. Distribution of M5 ganglioside was studied in unfertilised and fertilised eggs of the sea urchin Hemicentrotus pulcherrimus by indirect immunofluorescence microscopy. In the cortices of unfertilised eggs, anti-M5 antibody strongly stained the submembranous, polygonal and tubular network of endoplasmic reticulum that was revealed by a membrane-staining dye, DiIC18(3). In addition to the cortical network of endoplasmic reticulum, at least two morphologically distinct vesicles were positive to the antibody. In the cortices isolated from fertilised eggs 30 min after insemination, the antibody stained only a similar network of endoplasmic reticulum, presumably the one reconstructed 5-10 min after fertilisation. During mitosis the endoplasmic reticulum is known to aggregate within the asters of the mitotic apparatus. Indeed, the antibody stained the asters and (more strongly) the vesicular components attaching to the periphery of the mitotic apparatus.

Abstract
The carbohydrate structures of the major glycosphingolipids from the liver of the rainbow trout Oncorhynchus mykiss have been examined. We have isolated and identified four major neutral (glucosylceramide, galactosylceramide, lactosylceramide, and globoside) and five acidic (sulfatide, GM3, GM2, GD1a, and 9-O-Acetyl GD3) glycosphingolipids from trout liver. They have been characterized by 1H nuclear magnetic resonance spectroscopy, methylation analysis, fast atom bombardment mass spectrometry, and specific monoclonal antibodies. Significantly, the relatively scarce ganglioside 9-O-acetyl GD3 was found to comprise approximately 23% of the total ganglioside content of normal rainbow trout liver. 9-O-Acetyl GD3 is, however, abundant in human melanoma and as such, trout liver may be a suitable source of this antigen.

Abstract
An unusual sialoglycolipid containing D-glucose, D-galactose, L-arabinose and N-acetylneuraminic acid was purified from the total lipid extract of hepatopancreas of the starfish Patiria pectinifera. The structure of the sialolipid was studied by total and partial acid hydrolysis, methanolysis, periodate oxidation, methylation, chromium trioxide oxidation and enzymatic hydrolysis. The oligosaccharide chain of the sialolipid is branched: N-acetylneuraminic acid is located in the inner part of the carbohydrate chain; the arabinose residues are in furanose forms and are located at the non-reducing ends of the carbohydrate chain. The long-chain bases are C16-, C17- and C18-phytospingosines with both branched and normal chains. Only alpha-hydroxy fatty acids are found, C22-, C23- and C24-alpha-hydroxy fatty acids represent approx. 95% of the total fatty acids.

Abstract
The glycosphingolipids have been found in many animal tissues, but the complexity of their molecular structure varies considerably among the different phyla. Relatively simple structures have been found in invertebrate species, while the most complex have been demonstrated in brain tissue of modern fishes and amphibians. The data on the phylogenetic distribution of the glycosphingolipids has been interpreted to indicate that a significant number of gene duplications, involving many different structural genes, may have occurred during a few specific periods of vertebrate evolution. The transition from invertebrate to jawless vertebrate, the divergence of rays and skates from true sharks, the advent of modern bony fishes and the transition from aquatic to terrestrial vertebrates, each could have veen accompained by duplications of genes involved in the synthesis and degradation of glycosphingolipids. The evolutionary study of such a multi-enzyme system may be one means to detect alterations in the genome as a whole. The apparent correspondence in time of these gene duplications involved in glycosphingolipid metabolism and periods of rapid vertebrate evolution which may have been accompanied by significant increases in the amount of cellular DNA suggests that such changes may have occurred via the mechanism of tetraploidization.

Abstract
The localization of sialoglycosphingolipids in the plasma membrane of sea urchin spermatozoa was studied by employing immunological methods including immunolysis of liposomal model membranes. The antibodies produced against these complex lipids were found to agglutinate various sea urchin spermatozoa differently. Both species differences and species similarities in the agglutination were found in spermatozoa of the echinoderm, the sea urchin and the starfish. The agglutination of the sea urchin spermatozoa was inhibited specifically by ceratain carbohydrates. Only a limited number of molecular species of sialoglycosphingolipid were localized at the surface of the plasma membrane of sea urchin spermatozoa cells. Moreover, topographical differences were found in the localization of the sialoglycosphingolipids at the cell surface of spermatozoa.
