Abstract
Polysialic acid (PSA), an α2,8-linked homopolymer of N-acetylneuraminic acid (Neu5Ac), is developmentally regulated and its expression is thought to be restricted to a few tissues in adults. Recently, we showed that two human pathogens expressed a derivative of PSA containing de-N-acetyl sialic acid residues (NeuPSA). Here we show that an epitope identified by the anti-NeuPSA monoclonal antibody, SEAM 3 (SEAM 3-reactive antigen or S3RA), is expressed in human melanomas, and also intracellularly in a human melanoma cell line (SK-MEL-28), a human T cell leukemia cell line (Jurkat), and two neuroblastoma cell lines (CHP-134 and SH-SY5Y). SEAM 3 binding induced apoptosis in the four cell lines tested. The unusual intracellular distribution of S3RA was similar to that described for the PSA polysialyltransferases, STX and PST, which are also expressed in the four cell lines used here. Interestingly, suppression of PST mRNA expression by transfection of SK-MEL-28 cells with PST-specific short interfering RNA (siRNA) resulted in decreased SEAM 3 binding. The results suggest further studies of the utility of antibodies such as SEAM 3 as therapeutic agents for certain malignancies.

Abstract
There is increasing evidence that cell-surface gangliosides play a role in tumor growth, progression and metastases. In order to determine the frequency of ganglioside GD3 in patients with metastatic malignant melanoma for further therapeutic trials, GD3 ganglioside expression was determined in 119 tissue samples. Of these melanomas, 93% (111/119) were R-24-positive, which indicates the value of this diagnostic marker for melanoma. To study the structural epitopes of gangliosides, 10 ganglioside antibodies with defined specificities and affinities were tested on over 100 fresh-frozen tissue specimens of human normal and melanoma tissues. All the antibodies tested recognize the ganglioside GD3, but vary in their cross-reactivity with other gangliosides. According to their epitope specificity, they can be divided into 5 groups. For example, the antibodies Z-21 and A-4 react like the previously established MAb R-24 with gangliosides GD3 and GQlb, and one MAb (Q-4) detects all gangliosides containing 2 connected sialic acids (GD3, GD2, GDlb, GTlb, GQlb). Specificity on TLC does not always correlate with specificity to melanoma tissues and vice-versa. For example, MAb A-4, which recognizes only GD3 and GQlb on TLC, shows no specific reactivity on tissues. Furthermore, antibodies with the same ganglioside specificity do not have the same staining pattern on human tissues. For example, MAb Z-21, which is directed against the same gangliosides as MAb R-24 on TLC, does not cross-react with as many neuroectodermal tissues as MAb R-24. Because of their distinct properties, some of these antibodies may be even more useful for immunodiagnosis and immunotherapy of malignant melanoma than MAb R-24.

Abstract
Cell-surface gangliosides have immunomodulatory effects that are presumed to play a role in tumour growth, progression, metastasis and therapy. To study the epitopes of gangliosides on human malignant melanomas and to search for monoclonal antibodies (Mabs) with superior immunological effector functions, 19 ganglioside antibodies were established. Specificity and affinity of nine antibodies of IgG3 isotype were evaluated by enzyme linked immunosorbent assay and thin layer chromatography with a panel of purified gangliosides. All antibodies recognised the ganglioside GD3, but their epitope specificity divided them into five groups. Their affinity constants for ganglioside GD3 ranged from 4.7 x 10(6) to 2.3 x 10(8), with 2 x 10(7) for Mab R-24. Two antibodies possessed a higher affinity for GD2 than for GD3. The functional properties of the antibodies were investigated in vitro. Differences in the degree of tumour lysis by complement fixation correlated with the affinity constants. Every ganglioside antibody differed in epitope recognition, affinity and cytotoxicity. Therefore some of these antibodies might even be more useful in the immunotherapy of malignant melanoma than Mab R-24.

Abstract
Among various tumor associated cell surface antigens, gangliosides, the glycosphingolipids that contain sialic acids, offer a variety of epitopes, some of which are preferentially expressed on melanoma cells. These surface components of the bilayered lipid membrane of tumor cells are the targets of active immunotherapy with melanoma vaccine. Purified gangliosides in aqueous solution form micelles and, at high density, form lactones. Their antigenic expression (physical conformation and orientation) on the cell surface is governed by the nature of the sphingosine and the fatty acids they contain. Evidence is accruing to show that the nature of the fatty acid moiety of gangliosides differs in normal and neoplastic cells. Gangliosides per se are not immunogenic and require extrinsic adjuvanticity. Preparation of a melanoma cell vaccine for active immunotherapy requires an understanding of the ganglioside profile of melanoma, the ganglioside-associated heterogeneity of melanoma, and the role of shed melanoma gangliosides in the immunosuppression of cell mediated and humoral immunity. In addition, the role of some of the anti-ganglioside antibodies in the elimination of shed gangliosides, the cytotoxic killing of tumor cells, as well as in the down-regulation of lymphocyte functions must be considered in the formulation of vaccine. Different strategies for augmenting the immunogenicity of melanoma associated gangliosides with melanoma vaccine are evaluated.

Abstract
The lacto series of glycolipids are only minor constituents in mammalian CNS and are found mostly during development. Expression of a significant amount (70 micrograms of neuraminic acid/g dry weight) of disialosyl-lacto-N-neotetraosylceramide (LD1) in adult mouse cerebellum is reported for the first time in the nervous system. The structure of this ganglioside was determined by hydrolysis with various glycosidases, immunochemical tests, sugar and fatty acid analyses after permethylation and capillary GLC-mass spectrometry, sugar linkage analysis of permethylated alditol acetates, and fast-atom bombardment-mass spectrometry of the native ganglioside. The structure of LD1 was determined to be NeuAc-NeuAc alpha 2-3Gal beta 1-4GlcNAc beta 1-3Gal beta 1-4Glc beta 1-1-ceramide. The major fatty acid was 18:0, and the long-chain base was C18-sphingenine. Mouse cerebellum also contained O-acetyl-LD1 and several other O-acetylated gangliosides as recognized by monoclonal antibodies ME311 and 3G5. The levels of LD1 and O-acetyl-LD1 in cerebellum increased during postnatal development. During development of the Purkinje cell degeneration mutant, pcd/pcd, the levels of both of these gangliosides in the cerebellum declined with the loss of Purkinje cells, a finding indicating that these gangliosides are primarily associated with Purkinje cells. In the cortex, LD1, O-acetyl-LD1, and O-acetyl GD3, like GD3, are developmentally regulated antigens and are only expressed in the fetal cortex and not to any significant extent in the adult.

Abstract
NTERA-2 cl.D1 human embryonal carcinoma (EC) cells were induced to differentiate by either bromodeoxyuridine (BUdR) or hexamethylene bisacetamide (HMBA), and also by retinoic acid. Following exposure to each of these inducers, the globoseries glycolipid antigens stage-specific embryonic antigens -3 and -4 (SSEA-3 and -4) and the glycoprotein antigen TRA-1-60, all characteristic of the human EC cell surface, underwent a marked reduction in expression within about 7 days. At the same time, the lactoseries glycolipid antigen SSEA-1, and ganglioseries antigens A2B5 (GT3) and ME311 (9-0-acetyl GD3) were induced in BUdR- and retinoic acid-treated cells. However, these antigens did not appear during the first 7-14 days of HMBA-induced differentiation. The observations of cell surface antigen expression were paralleled by analysis of glycolipids isolated from the cells by thin-layer chromatography. This analysis, in which the new monoclonal antibodies VINIS-56 and VIN-2PB-22 were included, also revealed expression of gangliosides GD3 and GD2 in all differentiated cultures, albeit at much lower levels following HMBA exposure than following retinoic acid or BUdR-exposure. Further, disialylparagloboside was detected in retinoic acid and BUdR-induced, but not HMBA-induced, cultures. Taken with morphological observations, the results suggest that HMBA induces differentiation of NTERA-2 cl.D1 EC cells along a pathway distinct from the pathway(s) induced by retinoic acid and BUdR.

Abstract
Micro lipid droplets fuse with each other in vivo to form larger precursors of milk lipid globules. The extent of fusion dictates the size range of lipid globules in milk. A cell-free system in which micro lipid droplet fusion can be induced has been developed. Fusion was promoted by calcium and a protein complex from cytosol. Exogenously supplied gangliosides were potent fusion-promoting agents. Endogenous gangliosides were detected on micro lipid droplet surfaces by immunocytochemical localization. Monoclonal antibody to disialyllactosylceramide (GD3) inhibited micro lipid droplet fusion. These observations are suggestive of a role for gangliosides in micro lipid droplet fusion in situ.

Abstract
Monoclonal antibody (MAb) R24 was previously shown to be directed toward ganglioside GD3 [Pukel, C. S., Lloyd, K. O., Travassos, L. R., Dippold, W. G., Oettgen, H. F., and Old, L. J. (1982) J. Exp. Med. 155, 1133-1147]. The structural specificity of the MAb has now been further characterized based on binding to structurally related glycolipids, including four GD3 derivatives with different N-acetylneuraminic acid (NeuAc) and N-glycolylneuraminic acid (NeuGc) substituents. Three assay systems (enzyme immunostaining on thin-layer chromatography, enzyme-linked immunosorbent assay, and immune adherence inhibition assay) were used. MAb R24 was found to react with (NeuAc-NeuAc-)GD3 and (NeuAc-NeuGc-)GD3 but not with (NeuGc-NeuAc-)GD3 or (NeuGc-NeuGc-)GD3. These results clearly indicate that the outer sialic acid (Sia) moiety of GD3 is crucial and must be a NeuAc residue, while the inner sialic acid is less involved in binding to the MAb and can be either NeuAc or NeuGc. The MAb was also found to cross-react weakly with two gangliosides, GT1a and GQ1b, but none of other gangliosides nor neutral glycolipids tested reacted. These findings suggest that the epitope detected by MAb R24 is the trisaccharide structure NeuAc alpha 2----8Sia alpha 2----3Gal-, which must be in a terminal position.

Abstract
Gangliosides from cell cultures established from melanocytic lesions, representing different stages of melanoma tumor progression, were analyzed by chemical and immunological means on thin-layer chromatograms. The GD2 ganglioside and N-acetylgalactosaminyl transferase, which catalyzes the biosynthesis of GD2 from its precursor GD3, were detected in cultures established from advanced primary and metastatic melanomas, but not in cultures of normal melanocytes. Immunohistochemical studies on tissue sections from all progression stages confirmed GD2 expression only in these advanced lesions. A distinct biochemical event thus coincides with the onset of faster growth and acquisition of metastatic competence in human melanoma tumor progression.
