Abstract
Adenomyosis is frequently observed in premenopausal women, and oral dienogest is the recommended treatment to target the underlying pathology and improve the symptoms. This retrospective study investigated the association of Lewis (b) antigen expression with outcomes of dienogest therapy among women with adenomyosis. Records from a total of 342 adenomyosis patients were analysed, who were prescribed with oral dienogest for a maximum of 16 weeks. Expression levels of Lewis (b) antigen were measured to categorize all patients into either Le (b)- and Le(b)+ groups. Treatment outcomes, in terms of uterine volume, menstrual flow, pain symptoms and quality of life, were compared between the two groups. While oral dienogest therapy showed considerable clinical efficacy in both groups of patients, the extent of improvements in treatment outcomes was significantly more pronounced in Le (b)- group than Le (b)+ group, with respect to treatment time, uterine symptoms, menstrual flow, pain symptoms and quality of life. No difference in adverse effects was observed between the two groups. Expression of Lewis (b) blood group antigen interferes with oral dialogist therapy among women with adenomyosis.

Abstract
DC-SIGN is an immune C-type lectin that is expressed on both immature and mature dendritic cells associated with peripheral and lymphoid tissues in humans. It is a pattern recognition receptor that binds to several pathogens including HIV-1, Ebola virus, Mycobacterium tuberculosis, Candida albicans, Helicobacter pylori, and Schistosoma mansoni. Evidence is now mounting that DC-SIGN also recognizes endogenous glycoproteins, and that such interactions play a major role in maintaining immune homeostasis in humans and mice. Autoantigens (neoantigens) are produced for the first time in the human testes and other organs of the male urogenital tract under androgenic stimulus during puberty. Such antigens trigger autoimmune orchitis if the immune response is not tightly regulated within this system. Endogenous ligands for DC-SIGN could play a role in modulating such responses. Human seminal plasma glycoproteins express a high level of terminal Lewis(x) and Lewis(y) carbohydrate antigens. These epitopes react specifically with the lectin domains of DC-SIGN. However, because the expression of these sequences is necessary but not sufficient for interaction with DC-SIGN, this study was undertaken to determine if any seminal plasma glycoproteins are also endogenous ligands for DC-SIGN. Glycoproteins bearing terminal Lewis(x) and Lewis(y) sequences were initially isolated by lectin affinity chromatography. Protein sequencing established that three tumor biomarker glycoproteins (clusterin, galectin-3 binding glycoprotein, prostatic acid phosphatase) and protein C inhibitor were purified by using this affinity method. The binding of DC-SIGN to these seminal plasma glycoproteins was demonstrated in both Western blot and immunoprecipitation studies. These findings have confirmed that human seminal plasma contains endogenous glycoprotein ligands for DC-SIGN that could play a role in maintaining immune homeostasis both in the male urogenital tract and the vagina after coitus.

Abstract
The cholesterol-dependent cytolysins (CDCs) are a large family of pore-forming toxins that often exhibit distinct structural changes that modify their pore-forming activity. A soluble platelet aggregation factor from Streptococcus mitis (Sm-hPAF) was characterized and shown to be a functional CDC with an amino-terminal fucose-binding lectin domain. Sm-hPAF, or lectinolysin (LLY) as renamed herein, is most closely related to CDCs from Streptococcus intermedius (ILY) and Streptococcus pneumoniae (pneumolysin or PLY). The LLY gene was identified in strains of S. mitis, S. pneumoniae, and Streptococcus pseudopneumoniae. LLY induces pore-dependent changes in the light scattering properties of the platelets that mimic those induced by platelet aggregation but does not induce platelet aggregation. LLY monomers form the typical large homooligomeric membrane pore complex observed for the CDCs. The pore-forming activity of LLY on platelets is modulated by the amino-terminal lectin domain, a structure that is not present in other CDCs. Glycan microarray analysis showed the lectin domain is specific for difucosylated glycans within Lewis b (Le (b)) and Lewis y (Le (y)) antigens. The glycan-binding site is occluded in the soluble monomer of LLY but is apparently exposed after cell binding, since it significantly increases LLY pore-forming activity in a glycan-dependent manner. Hence, LLY represents a new class of CDC whose pore-forming mechanism is modulated by a glycan-binding domain.

Abstract
Unique CD16(-) natural killer (NK) cells appear in the human cycling endometrium and acutely increase in number after ovulation. Selective recruitment from peripheral blood (PB) CD16(-) NK cells is a potential mechanism for the postovulatory increase of these NK cells. The interaction between selectin L, an adhesion molecule playing a critical role in leukocyte extravasation, and its ligands may be involved in this phenomenon. We investigated the menstrual cycle-dependent fluctuation of selectin L expression on PB CD16(-) NK cells and selectin L ligand expression in the human endometrial endothelium. The expression of selectin L on PB CD16(-) NK cells was constantly high throughout the menstrual cycle compared with other PB CD16(+) NK cells and non-NK lymphocytes. Among eight selectin L ligands examined, podocalyxin-like, mucosal addressin cell adhesion molecule-1 (MADCAM1) and chondroitin sulfate proteoglycan 2 (CSPG2) were localized in the endometrial endothelium. Semiquantitative score of immunostaining intensity in the endometrial endothelium for MADCAM1 was highest in the late secretory phase, whereas that for CSPG2 peaked throughout the secretory phase. There was a strong positive correlation between the number of endometrial NK cells and the semiquantitative score for CSPG2. Three active isoforms of CSPG2 mRNA were detected in the human endometrium. These findings support the idea that the interaction between selectin L and selectin L ligands functions in the postovulatory selective recruitment of PB CD16(-) NK cells into the human endometrium.

Abstract
INTRODUCTION There is sufficient evidence that blood group related Lewis antigens are tumour-associated molecules. The Lewisy and Lewisb antigens are complex carbohydrates that are over-expressed by breast, lung, colon and ovarian cancers. The SC101 mAb is a unique Lewisy/b binding antibody that binds to native and extended Lewisy and Lewisb haptens, displaying no cross reactivity with H type 1, H type 2, Lewisx or normal blood group antigens. METHODS Immunohistochemical detection of Lewisy/b was performed on 660 formalin-fixed, paraffin embedded breast tumour specimens using a streptavidin-biotin peroxidase technique. Tissue from these patients had previously been included in tissue microarrays. This cohort comprises a well characterized series of patients with primary operable breast cancer diagnosed between 1987 and 1992, obtained from the Nottingham Tenovus Primary Breast Carcinoma Series. This includes patients 70 years of age or less, with a mean follow up of 7 years. RESULTS Of the breast carcinomas, 370 of 660 (56%) were negative for Lewisy/b expression, 110 (17%) cases showed a low level of expression (<25% of positive cells) and only 54 cases (8%) showed extensive expression of Lewisy/b (>75% of positive cells). We found significant positive associations between histological grade (p < 0.001), Nottingham Prognostic Index (p = 0.016), tumour type (p = 0.007) and the level of Lewis y/b expression. There was a significant correlation between the proportion of Lewisy/b positive tumour cells and survival in lymph-node negative patients (p = 0.006). CONCLUSION The unique epitope recognised by SC101 mAb on Lewisy/b hapten is over-expressed on breast tumour tissue compared with normal breast. In this large series of invasive breast cancers, higher expression of Lewisy/b was more often found in high grade and poor prognosis tumours compared to good prognosis cancers. Moreover, in lymph node negative breast carcinomas, over-expression of Lewisy/b hapten was associated with significantly decreased patient survival.

Abstract
AIM To characterize serum elevations of carbohydrate antigens; DU-PAN-2, CA19-9, sialyl Lewisx and CA125 in endometrial adenocarcinomas (EMACs), particularly focusing on the clarification of DU-PAN-2 expression profiles. METHODS Sixty-four resected EMACs of endometrioid type were used. The preoperative serum values of four markers were measured and comparatively analyzed regarding the relationship between histological grade and clinicopathological stage. RESULTS The overall ratios of positive cases were 26.2% for DU-PAN-2, 25.0% for CA19-9, 13.6% for sialyl Lewisx, and 35.5% for CA125. DU-PAN-2 decreased as the grading went up (G1: 410.3 +/- 243.8 to G3: 246.7 +/- 90.0 U/mL), however, the reverse was true with CA19-9 (G1: 123.9 +/- 147.4 to G3: 320.0 +/- 180.0 U/mL). Sialyl Lewisx showed a strong tendency towards high elevation in G1 (346.3 +/- 102.6 U/mL), compared to G3 (< 2.5 U/mL). CA125 increased markedly as the grading went up (G1: 43.5 +/- 6.3 to G3: 578.0 +/- 10.0 U/mL). During staging-up from I + II to III + IV, the positive ratios inclined in all four markers as follows: DU-PAN-2, 18.4-53.3%; CA19-9, 20.4-40.0%; sialyl Lewisx, 11.4-22.2%; CA125, 31.8-44.4%. Serum elevations and positive ratios were correlated for DU-PAN-2, CA19-9 and CA125, while the reverse relationship was found for sialyl Lewisx. CONCLUSION It is suggested that DU-PAN-2 tends to be produced more in well-differentiated components of EMACs than in poorly differentiated ones. Since approximately half the cases with EMAC were serologically positive for DU-PAN-2 in stage III + IV, the marker is believed to be of much use for monitoring the cases with an extrauterine extent.

Abstract
The binding of xenoreactive natural antibodies to the Galalpha1-3Galbeta1-4GlcNAc (alpha-galactose) oligosaccharide epitope on pig cells activates the recipient's complement system in pig to primate xenotransplantation. Expression of human alpha-1, 2-fucosyltransferase in pigs has been proposed as a strategy for reducing the expression level of the alpha-galactose epitope, thereby rendering the pig organs more suitable for transplantation into humans. The aim of this study was to examine how the cell surface expression of alpha-galactose, H, and related fucosylated and sialylated structures on a pig liver endothelial cell line is affected by transfection of human alpha-1,2-fucosyltransferase cDNA. Nontransfected and mock-transfected cells expressed alpha-galactose, alpha-2,3-sialylated, and alpha-2,6-sialylated epitopes strongly, with low level expression of type 2 H and LewisX. By contrast, expression of the H epitope was increased 5-8-fold in transfected cells with a 40% reduction in the expression of alpha-galactose epitope and a 50% decrease in sialylation, as measured by binding of Maackia amurensis and Sambuccus nigra agglutinins. LewisX expression was reduced to background levels, while the LewisY neoepitope was induced in human alpha-1,2-fucosyltransferase-expressing pig cells. The activities of endogenous alpha-1,3-galactosyltransferase, alpha-1,3-fucosyltransferases, and alpha-2,3- and alpha-2, 6-sialyltransferases acting on lactosamine were unaffected. Our results show that a reduction in alpha-galactose epitope expression in porcine endothelial cells transfected with human alpha-1, 2-fucosyltransferase cDNA may be achieved but at the expense of considerable distortion of the overall cell surface glycosylation profile, including the appearance of carbohydrate epitopes that are absent from the parent cells.

Abstract
Type-1 chain histo-blood group antigens such as the Lewis (Le)a, monosialosyl-Le(a), Le(b) and H antigens show an increased expression in endometrial carcinomas. However, the possibility that these antigens are expressed under genetic or hormonal influence in endometrial carcinomas has not been considered. In the present study, the expression of type-1 chain carbohydrate antigens in normal and malignant endometrium was evaluated by immunohistochemistry and related to both genetic and hormonal factors. The glands of normal, non-secretory endometria expressed, in contrast with surface epithelial cells, Le(a), Le(b), disialosyl-Le(a), and H determinants infrequently. Adenomatous hyperplasias and endometrial carcinomas showed an increased expression of type-1 chain carbohydrates that was qualitatively influenced by the erythrocyte Lewis phenotype and the secretor status. Whereas Le(a+b-) non-secretors mainly accumulated Le(a) antigen, and only limited amounts of Le(b) antigen, Le(a-b+) secretors expressed H, Le(b) and Le(a) antigens. The expression of type-1 chain antigens showed no association with the serum-oestrogen level or to the hormone-receptor status. Thus the Lewis secretor status has a qualitative influence on the increased expression of type-1 chain antigens, which, however, seem to be unrelated to hormonal factors. Our findings suggest an increased activity of the Se-gene-defined or a closely related fucosyl-transferase in neoplastic endometrial epithelial cells.

Abstract
Changes in expression of histo-blood group ABH and Lewis antigens are common alterations in carcinomas. Using immunohistochemistry, we have evaluated the expression of type-2 histo-blood group antigens in normal and malignant endometrial tissues in relation to genetic and hormonal factors. The Le(x), sialosyl-Le(x), and Le(y) antigens were inconstantly expressed in the normal endometrium. The expression was uninfluenced by the secretor status but was related to the ABO blood group status in Oestradiol (E2) stimulated endometria. Le(y) was expressed most frequently in proliferating endometria from blood group 0 individuals. Le(x) and Le(y) were maximally expressed in atrophic endometria, and Le(x) and Le(y) staining scores correlated inversely with serum levels of E2 in normal, non-secretory endometria. No correlation was found in adenomatous hyperplasias and endometrial carcinomas, which when compared with atrophic endometria, showed a loss of Le(x) and Le(y) and an increased H-carbohydrate expression at apical membranes. Carcinomas from non-secretors showed lower expression of Le(y) and H-antigens than carcinomas from secretors. Our findings suggest that the genetic and hormonal influence on glycosylation based on type-2 chain carbohydrates differ between normal and malignant endometrium. This difference is probably related to specific tumour-associated qualitative and quantitative changes in the fucosyltransferases.

Abstract
Estrogen (ER) and progesterone (PR) hormone receptor status and levels were correlated with blood group antigen (A, B, H, Lewis-a and Lewis-b) expression in 48 cases of human breast cancer. Reduced expression of all the blood group antigens was observed with statistically significant reductions for H, Lewis-a and Lewis-b (P < 0.05). The proportions of ER- and PR-positive breast cancers staining for Lewis-b were greater than in hormone-receptor-negative cancers but the differences were not significant. The loss of Lewis-b antigen in breast cancer increased with tumor grade but did not correlate with axillary lymph node metastases. Loss of Lewis-b antigen is probably not a predictor of local recurrence and survival in the short period of observation. We conclude that the loss of H, Lewis-a and, especially, Lewis-b in breast cancer reflects the invasiveness of breast cancer and that Lewis-a and b expression is probably only marginally and not significantly affected by steroid hormone receptor status and levels.

Abstract
Epithelia frequently express blood group antigens and these are often perturbed in neoplasia. This study has characterized the range of expression of ABH and Lewis terminal structures and the Ii backbone chains in the normal human cervix by semiquantitative immunohistochemistry. Effects of the secretor gene were defined by determination of salivary secretor status. Modifications of blood group antigen expression in cervical adenocarcinoma were also addressed. Normal cervical squamous and glandular epithelia showed a range of expression of the antigens studied. Lewis-gene-negative cases showed no expression of Lewis antigens. Secretor status had no effect on ABH expression in squamous epithelium, but it did have a marked effect on ABH expression in glands and on Le(b) expression in both squamous and glandular epithelia. Patterns of expression of i chains in squamous epithelium suggest that these may be the carriers of ABH and Lewis antigens in a proportion of cases. Distinct patterns of expression were seen in glandular tubal metaplasia and in endothelium. Adenocarcinomas showed topographical rather than quantitative changes in blood group antigen expression with more extensive luminal expression of ABH, Lewis and Ii structures than that seen in normal glands. This change is distinct from those usually associated with malignancy.

Abstract
The blood group ABO(H) determinants are major allogenic antigens in both erythrocytes and tissue of man. These antigens and related carbohydrates are markers of cellular maturation and differentiation in many epithelial tissues and have recently attracted great interest as tumor-associated antigens. Previous studies of endometrial tissues have indicated that glycosylation in this tissue may be related to hormonal stimulation. We have investigated the immunohistochemical distribution of type-2 chain histo-blood group-related carbohydrates in specimens of normal, cycling endometria obtained from hysterectomies on women with known ABO/Lewis erythrocyte type and saliva secretor status. N-acetyllactosamine and Le(x) were demonstrated to be uninfluenced by the genetic background. A and Ale(y) antigens were exclusively demonstrated in endometria from blood group A individuals, while Le(y) was expressed in endometria from blood group 0 individuals mainly. The precursor N-acetyllactosamine as well as the terminal H, A, and ALe(y) antigens were shown in only a few cells. In contrast, N-acetyllactosamine substituted by sialic acid and/or fucose residues (Le(x), sialosyl-Le(x), Le(y)) were demonstrated in epithelial cells of normal, cycling endometrium, but with both quantitative and qualitative differences in staining relating to the menstrual cycle, indicating that type-2 chain antigens are expressed under both genetic and hormonal influence in human cycling endometrium.

Abstract
Immunohistochemical examination was performed of serial sections of 24 normal human adult cervical tissues and 53 human cervical carcinomas including 36 cases with lymph node metastasis. For this investigation, monoclonal antibodies directed to Lewis-X, Lewis-Y, sialyl-dimeric Lewis-X (SDLX), sialyl-Tn (STn) and carcinoembryonic antigen (CEA) were used. STn and CEA antigens were expressed very weakly in the normal cervical epithelium but strongly in the cancer cells, indicating the antigens to be oncogenic antigens of cervical squamous cell carcinoma. No significant difference in immunoreactivity was observed between primary and metastatic lesions of carcinoma or between primary lesions with and without metastasis. However, the expression patterns of STn and Lewis-Y antigens were quite different between primary lesions and metastatic lesions. In primary lesions the cancer cell nests tended to be stained centrally, but in metastatic lesions the cancer cell nests tended to be stained peripherally. This finding may reflect an important role of these carbohydrate chains in the process of metastasis of cervical squamous cell carcinoma to regional lymph nodes.

Abstract
The Lewis blood group antigens (Lewis-a [Lea] and Lewis-b [Leb]) and their precursors are present on various normal human epithelial cell surfaces. The authors examined 35 benign and malignant human breast lesions using mouse monoclonal antibodies to synthetic Lea and Leb carbohydrate antigens. Normal breast lobular and ductal epithelium and benign breast lesions showed Leb staining but only occasional Lea staining. In invasive ductal carcinomas of breast, of all grades, a loss of Leb antigen staining was found in 80% of the breast cancer cases. This reduced Leb antigen expression increased with the grade of malignancy. Therefore, the loss of Leb blood group antigens on breast cancer cell surfaces may suggest altered fucosylation patterns in malignant cells and reflect the degree of malignancy and/or invasiveness.

Abstract
A total of 63 surgically resected esophageal carcinomas (including 49 superficial esophageal carcinomas) and histologically normal tissue adjacent to the superficial carcinoma (nontumorous epithelium) were examined immunohistochemically for the blood group antigens (BGA) A, B, H, Lewisa, Lewisb, Lewisx, and Lewisy. Deletion of an expected A, B or H antigen occurred in 12 (24.5%) of the 49 superficial carcinomas and three (21.4%) of the 14 advanced carcinomas. Incompatible expression of an unexpected A or B antigens occurred in only one case (1.6%) in the carcinoma. In the clinicopathologic study, there was a significant correlation between immunoreactivity of Lewisa and depth of cancer invasion (chi-square test, P less than 0.05). In the superficial carcinoma, there were significant correlations between immunoreactivity of Lewisx and lymph node status (chi-square test, P less than 0.05), immunoreactivity of Lewisy and prognosis (Z test, P less than 0.05), and incompatible expression of Lewisb for tumor against nontumorous epithelium and histologic variation (chi-square test, P less than 0.01). The functional significance of alternations in BGA expression that may be associated with oncogenesis is not clear. However, immunohistochemical determination of BGA may be a more advantageous marker to predict the patient's clinical course in superficial esophageal carcinoma.

Abstract
The expression of sialyl-Tn antigen (STn) in normal, hyperplastic and neoplastic tissues of the uterine endometrium was examined by immunoperoxidase staining of formalin-fixed, paraffin-embedded samples using the monoclonal antibody TKH-2, directed toward the STn structure (NeuAc 2-6GalNac 1-O-serine or threonine). STn was expressed in 13 of 18 normal postovulatory endometria with an increasing staining intensity and incidence in the late secretory phase. It was consistently absent in 10 proliferative endometria. None of 5 cystic, 4 adenomatous or 12 atypical hyperplasias expressed STn, but areas of severe cytological atypia in 3 atypical hyperplasias showed faint expression. STn expression was detected in 36 of 43 adenocarcinomas. Although the extent of staining varied from a few to most of the cancer cells, general staining was observed throughout the cytoplasm of cancer cells with increased staining of the luminal surface and frequent positive staining of intraluminal mucin. Thus, it is clear that STn is selectively expressed in cancer cells and shows restricted expression in normal and hyperplastic endometrial tissues. STn may be an early marker of malignant transformation and has potential for use as a diagnostic aid in the surgical pathology of the uterine endometrium.
