Abstract
In current infertility treatments it is necessary to evaluate uterine receptivity in each menstrual cycle. During the implantation period, the uterus goes through many complex orchestrated changes, including changes to the glycocalyx. The changes to the glycocalyx are due to sialylation, sulfation and fucosylation. Can the measurement of in-vivo uterine pH and/or oxidation-reduction potential (ORP) determine the alterations of uterine endometrium for implantation and evaluate prospective uterine receptivity? In the present study we assessed in vivo uterine pH and ORP during the early stages of pregnancy in naïve mice, as well as in a murine model of implantation failure created by local and transient suppression of signal transducer and activator of transcription 3. There was no change in the in vivo uterine pH between post-coitus Days 2 and 6. In vivo uterine ORP was significantly higher compared to the day before. One day before implantation began, uterine ORP was significantly decreased in the implantation failure group compared with the naïve and control groups. Receiver operator characteristic (ROC) curve analysis of uterine ORP as a predictor of non-conception showed an area under the ROC curve of 0.96 (95% confidence interval 0.92-1.00). Thus, in vivo uterine ORP could be a parameter to prospectively evaluate uterine receptivity.

Abstract
STUDY QUESTION Can vaginal bioelectrical impedance (VZ) electrophysiologically determine alterations of the endometrium in preparation for implantation? SUMMARY ANSWER VZ can electrophysiologically detect the sulfation and sialylation changes in the uterine glycocalyx in preparation for implantation. WHAT IS KNOWN ALREADY Uterine receptivity is associated with various glycosylation changes that affect negative charge density at the luminal epithelial cell surface. VZ has been used to monitor the oestrous cycle. STUDY DESIGN, SIZE, DURATION Pathogen-free Jcl:ICR mice, aged 8-10 weeks, were used in this study. We conducted the following three steps to test our hypothesis that VZ may be used to determine uterine receptivity. First, to investigate whether VZ could determine alteration of sulfation and sialylation in the uterine glycocalyx, VZ was measured in mice with induced artificial sulfation and sialylation changes in the uterine glycocalyx (galactose-3-O-sulfotransferase 2 (GP3ST) + α(1,3/1,4) fucosyltransferase gene (FucT-III)-transferred group (n = 15) and in LacZ (encoding for β-galactosidase)-transferred mice as a control group (n = 12)). Second, to investigate whether VZ could determine alterations of the endometrium in preparation for implantation, we measured VZ during the early stage of pregnancy (n = 12 each). Third, to investigate whether VZ could be used to evaluate uterine receptivity prospectively, VZ was measured in an implantation failure model mice. In 21 mice, local and transient suppression of signal transducer and activator of transcription-3 (Stat3) in the uterus were evaluated 1 day before implantation began, and 23 scramble decoy-transferred mice were used as a control group. PARTICIPANTS/MATERIALS, SETTING, METHODS The VZ was measured at a frequency of 1 kHz in Jcl:ICR mice. Data were analysed using the Kruskal-Wallis test with Dunn's multiple comparisons, or the Student's t-test or Wilcoxon's rank-sum test with the Shapiro-Wilk normality test. The values of VZ were analysed using receiver operating characteristic (ROC) curve analysis to identify the optimal cut-off point to determine if this parameter predicted non-pregnancy. MAIN RESULTS AND THE ROLE OF CHANCE Sulfation and sialylation changes induced in the luminal epithelial glycocalyx decreased the value of VZ. VZ showed a significant daily decrease during the early stage of pregnancy (Day 1.5 versus 2.5 p.c.: P < 0.005; Student's t-test, Day 2.5 versus 3.5 p.c.: P < 0.001; Wilcoxon's rank-sum test, Day 3.5 versus 4.5 p.c.: P < 0.005; Student's t-test, Day 4.5 versus 5.5 p.c.: P < 0.05; Student's t-test). One day before implantation began, VZ in the implantation failure model mice was significantly higher than in the control mice (P < 0.001, Wilcoxon's rank-sum test). The ROC curve analysis of VZ as a predictor of non-conception showed areas under the ROC curve of 0.91 (95% CI: 0.83-0.99). LIMITATIONS, REASONS FOR CAUTION Although it is influenced by surface charge in the uterine epithelium, the mechanism whereby VZ changes during early pregnancy is still unexplained. WIDER IMPLICATIONS OF THE FINDINGS Local bioelectrical impedance may help to prospectively evaluate uterine receptivity in women. Including the measurement of local bioelectrical impedance as part of a frozen-thawed embryo transfer strategy may improve the efficiency of ART.

Abstract
PURPOSE During the implantation period, the uterus goes through many complex, orchestrated changes, including alterations of the glycocalyx that are due to sialylation, sulfation, and fucosylation. A previous mouse study showed that the in vivo intrauterine oxidation-reduction potential (ORP) aided in determining the alterations in the uterine endometrium that are suitable for implantation and for evaluating prospective uterine receptivity, while the in vivo intrauterine pH did not. It was assessed if the in vivo intrauterine ORP could be a useful parameter to predict pregnancy in women. METHODS A prospective cohort study was conducted for patients who had received a frozen-thawed single embryo transfer in a programmed, hormonally controlled cycle. The in vivo intrauterine ORP was measured 3 times during the treatment cycle, at cycle days 9-10, 1 day before progesterone administration and immediately before the embryo transfer. RESULTS The amount of in vivo intrauterine ORP at 9-10 days after the start of menstrual bleeding was significantly lower in the pregnant group than in the non-pregnant group. A receiver-operator characteristic curve analysis of the intrauterine ORP as a predictor of non-conception showed an area under the curve of 0.80. CONCLUSION The in vivo intrauterine ORP could be a useful parameter to predict pregnancy for the frozen-thawed embryo transfer treatment cycle.

Effective Selection of a Well-Differentiated Type of Human Uterine Endometrial Carcinoma Cells by Transfection of the Sulfotransferase Gene and Possible Association of Sulfoglycolipids With Well-Differentiated Phenotypes. Int J Gynecol Cancer 2017; 27:267-273.

Abstract
OBJECTIVES Sulfatide has been shown to be characteristically increased on the apical surface of the normal endometrium at the secretory phase, and to be related with the formation of the glandular structure and the secretion of mucin from glands for the implantation of a fertilized egg. Additionally, sulfatides are expressed in the well-differentiated type, but not in the poorly differentiated type, of endometrial carcinomas. This suggests that sulfatides are a molecular marker of differentiated phenotypes. To further elucidate the biological significance of sulfoglycolipids, we transfected the sulfotransferase gene into endometrial carcinoma-derived cells without sulfoglycolipids and compared their glycolipid compositions and phenotypes with those of the original cells. MATERIALS AND METHODS The glycolipid sulfotransferase gene was transfected into endometrial carcinoma-derived SNG-II cells, the resultant transfected cells being found to frequently form a domelike structure, and some of them were selected as SNG-II-GST cells. We compared the glycolipid compositions and phenotypes of SNG-II and SNG-II-GST cells. RESULTS Although the original SNG-II cells grew in a paving stone pattern, SNG-II-GST cells formed a domelike structure. SNG-II-GST cells exhibited high GST activity and contained sulfoglycolipids, IISO3-LacCer and IISO3-Gg3Cer, which were not found in SNG-II cells. The amounts of sulfoglycolipids in SNG-II-GST cells were 1.5 times higher than those of gangliosides, and the proportions of LacCer and GM3 in SNG-II-GST cells were greatly different from those in SNG-II cells. SNG-II and SNG-II GST cells exhibited poorly differentiated and well-differentiated phenotypes on histochemical examination of cancerous nodules in nude mice. However, by means of an oxygen electrode, SNG-II-GST cells were found to be more resistant to anticancer drugs than SNG-II cells. CONCLUSION Enhanced expression of sulfoglycolipids in poorly differentiated cells is a feasible means of selecting well-differentiated ones, and sulfoglycolipids are involved in the well-differentiated phenotype like those in the normal endometrium at the secretory phase.

Abstract
Based on our previous analysis of neutral glycolipids in the human endometrium, the present authors already reported that the concentrations of glucosylceramide, lactosylceramide and globotriaosylceramide (Gb3Cer), in which both fatty acids and sphingosines in the ceramides are hydroxylated, exhibit a marked increase during the luteal phase of the menstrual cycle. It is also well known that poorly differentiated endometrial adenocarcinoma exhibits a more rapid progression and a worse response to therapy than well-differentiated endometrial adenocarcinoma. To examine the molecular background of well-differentiated and poorly differentiated cancers, the levels of neutral glycolipids in tumor tissues from endometrial carcinoma displaying different degrees of differentiation were measured. The composition of neutral glycolipids in tumor tissues was determined, and ceramide structures that were specifically expressed in well-differentiated endometrial carcinomas were investigated using biochemical analytical methods, including lipid extraction, enzyme digestion, thin-layer chromatography (TLC), gas-liquid chromatography and mass spectrometry. Well-differentiated adenocarcinoma contained numerous structurally unknown glycolipids that exhibited slower migration than globotetraosylceramide (Gb4Cer). In the case of Gb3Cer, three bands appeared on TLC in well-differentiated cancer, but only two bands appeared in the poorly-differentiated cancer. This difference was associated with the fatty acid composition of ceramide, since non-hydroxy fatty acids with ≥20 carbon atoms were increased in well-differentiated cancer, while α-hydroxy fatty acids were increased in poorly differentiated cancer. Similarly, there were two bands on TLC of Gb4Cer from well-differentiated cancer, but only one band in poorly differentiated cancer, and the long-chain base of ceramide was observed to contain phytosphingosine in well-differentiated cancer. It was demonstrated in endometrial cancer that the structure of ceramide molecules changes with the extent of tumor differentiation. These findings suggest that hydroxylated ceramides contribute to the well-differentiated phenotype of endometrial adenocarcinoma.

Enhanced expression of sulfatide, a sulfated glycolipid, in well-differentiated endometrial adenocarcinoma. Int J Gynecol Cancer 2013; 22:1192-7.

Abstract
OBJECTIVES It is well known that a poorly differentiated endometrial adenocarcinoma shows more rapid progression and a worse response to therapy than a well-differentiated endometrial adenocarcinoma. Qualitative and quantitative changes of cell surface glycolipids occur during neoplastic transformation. Sulfatide is one of the sulfated glycolipids in the cell membrane that may have an important role in various functions such as cell adhesion. To examine the molecular background of the morphological and biological features of well-differentiated and poorly differentiated cancer, we measured the levels of lipids, especially glycolipids, in tumor tissues from patients with endometrial carcinoma. MATERIALS AND METHODS We determined the composition of lipids and glycolipids in tumor tissues, investigated glycosyltransferase messenger RNA expression by the reverse transcription-polymerase chain reaction, and assessed the localization of galactosylceramide sulfotransferase (an enzyme involved in sulfatide biosynthesis) by immunohistochemical staining. RESULTS No significant differences were observed between well-differentiated and poorly differentiated cancer with respect to the levels of cholesterol ester, cholesterol, phospholipids, cholesterol sulfate, ceramides, neutral glycolipids of the globo series, and GM3 ganglioside. However, the amount of sulfatides in well-differentiated tumors was significantly greater than that in poorly differentiated tumors, which was confirmed by thin-layer chromatography and immunostaining with a monoclonal antisulfatide antibody. Altered expression of sulfatide was found to be secondary to a change of galactosylceramide sulfotransferase messenger RNA expression. Immunohistochemical staining revealed that galactosylceramide sulfotransferase expression was characteristically observed in glandular areas but not in solid areas. CONCLUSION These findings suggest that sulfatide contributes to the well-differentiated phenotype of endometrial adenocarcinoma and that it is being expressed in normal uterine endometrium at sites of gland formation during the luteal phase, as we have previously reported.

Abstract
Cholesterol sulfate (CS) is a major sterol sulfate in human plasma that is detected in the uterine endometrium. CS plays a role in steroidogenesis, cellular membrane stabilization, and regulation of the skin barrier. We previously reported that CS increased in rabbit endometrium during the implantation period. Recently, CS has been reported to be a ligand of retinoic acid receptor-related orphan receptor alpha (RORA). NR1D1 is one of the genes regulated by RORA. In the present study, we investigated the regulation of RORA and NR1D1 by CS in human endometrium. We determined the association-dissociation curves for the interaction of CS with RORA and the kinetic rates by surface plasmon resonance. Immunohistochemical staining and in situ hybridization revealed that RORA and NR1D1 were expressed in human endometrial stromal and epithelial cells. CS treatment significantly induced the mRNA expression of RORA and NR1D1 mRNA in ESCs. The results of a luciferase assay showed that RORA significantly activated the human NR1D1 promoter regardless of CS. Our results suggest that CS regulates the expression of RORA responsive genes in human endometrial cells but not as a ligand for RORA.

Abstract
This study aimed to promote gland formation in cells derived from endometrial cancer, and assess the relevance of sulfolipids by performing culture with type I collagen. Tumors were developed in nude mice using cultured cell lines, gland formation was induced by culture with type I collagen and the composition of tumor cell sulfolipids was analyzed. Results showed that after culturing the cells on type I collagen gel, the gel was floated. Another layer of gel was placed on top so that the cells were sandwiched between two layers. Using this method, it was possible to induce gland formation in cells that formed only poorly differentiated tumors in nude mice. Mucous staining and electron microscopy demonstrated polarity of the glands. The cell lines that showed gland formation expressed sulfolipids, but not cholesterol sulfate. In conclusion, type I collagen and sulfolipids are involved in the process of gland formation in endometrioid adenocarcinoma.

Abstract
The monohexoside glycosphingolipids (GSLs), galactosylceramide (GalC), glucosylceramide (GluC), and their sulfated forms are abundant in cell membranes from a number of tissues. Carbohydrate-carbohydrate interactions between the head groups of some GSLs can occur across apposed membranes and may be involved in cell-cell interactions. In the present study, the ability of GluC to participate in trans interactions with galactosylceramide I(3) sulfate (CBS) was investigated by transmission electron microscopy (TEM) and Fourier transform infrared spectroscopy. Gaucher's spleen GluC had polymorphic phase behavior; in its metastable state, it formed large wrinkled vesicles. It transformed to a stable state via an intermediate state in which the surface of the vesicles consisted of narrow ribbons. In the stable state, the narrow ribbons split off from the surface to form membrane fragments and flat and helical ribbons. The strength of the intermolecular hydrogen bonding interactions between the carbonyls increased in the order metastable<intermediate<stable state. Aqueous dispersions of GluC and CBS were combined to allow trans carbohydrate-carbohydrate interaction across apposed bilayers, or the lipids were premixed in a solvent before hydration to allow lateral cis interactions. Premixed dispersions of NFA-GluC and CBS remained in the metastable state even when incubated under stable state conditions. When NFA-GluC dispersions were combined with CBS dispersions, they had a small effect on each other's amide groups in the metastable state. Furthermore, conversion of NFA-GluC to the stable state was inhibited, although it reached the intermediate state, suggesting that some degree of trans interaction between these two lipids occurred.

Abstract
Human immunodeficiency virus-1 (HIV-1) is primarily a sexually transmitted disease. Identification of cell populations within the female reproductive tract that are initially infected, and the events involved in transmission of infection to other cells, remain to be established. In this report, we evaluated expression of HIV receptors and coreceptors on epithelial cells in the uterus and found they express several receptors critical for HIV infection including CD4, CXCR4, CCR5 and galactosylceramide (GalC). Moreover, expression of these receptors varied during the menstrual cycle. Expression of CD4 and CCR5 on uterine epithelial cells is high throughout the proliferative phase of the menstrual cycle when blood levels of oestradiol are high. In contrast, CXCR4 expression increased gradually throughout the proliferative phase. During the secretory phase of the cycle when both oestradiol and progesterone are elevated, CD4 and CCR5 expression decreased whereas CXCR4 expression remained elevated. Expression of GalC on endometrial glands is higher during the secretory phase than during the proliferative phase of the menstrual cycle. Because epithelial cells line the female reproductive tract and express HIV receptors and coreceptors, it is likely that they are one of the first cell types to become infected. The hormonal regulation of HIV receptor expression may affect a woman's susceptibility to HIV infection during her menstrual cycle. Moreover, selective coreceptor expression could account for the preferential transmission of R5-HIV-1 strains to women. In addition, these studies provide evidence that the uterus, and potentially the entire upper reproductive tract, are important sites for the initial events involved in HIV infection.

Abstract
Cytosolic sulfotransferases play essential roles in regulating the activities and transfer of steroids. To evaluate their biological significance in the murine uterus and placenta during the course of gestation, we determined their activities with several steroids as substrates. Activated estrogen sulfotransferase (EST) was found in the placenta and uterus during the late gestational period. Reverse-transcribed cDNA of murine placental EST (mpEST) was isolated from mouse placenta at 18 days of gestation and its expression in the tissue coincided with a change in its enzyme activity. The open-reading frame of mpEST encodes a protein composed of 296 amino acids with a predicted molecular mass of 35.5 kDa and was revealed to be an isoform of the murine testis-specific EST gene (99.7%). Also, the amino acid sequence of mpEST showed 49.6 and 77.9% homology with human placental and endometrial EST, respectively, showing that it corresponds to human endometrial EST. COS-7 cells transfected with mpEST exhibited sulfotransferase activity with the phenolic hydroxy groups of steroids and artificial substrates. The best acceptor substrate was estrogen.

Abstract
3'-Sulfogalactolipids(SGLs), sulfogalactosyl ceramide (SGC), and sulfogalactoglycerolipid (SGG) bind to the N-terminal ATPase-containing domain of members of the heat shock protein 70 family. We have probed this binding specificity using a series of synthetic positional sulfated or phosphorylated glycolipid analogues, containing either a long-chain bisalkyl hydrocarbon-2-(tetradecyl)hexadecane (B30) or C(18) ceramide (SGC(18)) backbone. By TLC overlay and receptor ELISA, recombinant hsc70 bound ceramide-based glycoconjugates having 3'- or 4'-sulfogalactose glycone moieties and the 4'-sulfogalactose positional isomer conjugated to B30. Hsc70 binding was significantly decreased to the 3'-sulfogalactose conjugated to the long-chain branched alkane. 3'-Sulfoglucose conjugated to B30 was not bound, nor were similarly conjugated di-, tri-, and tetra-sulfated or phosphorylated galactolipids. These results highlight the importance of the position, rather than the number of sulfate esters within the galactose ring. This binding selectivity was shared by the sea urchin hsp70-related sperm receptor. A 3'-SGC-based soluble inhibitor, in which the acyl chain was replaced with an adamantyl group, inhibited binding of hsc70 to both 3'- and 4'-SGC species with an IC(50) of 50 and 75 microM, respectively, indicating a shared sulfogalactose binding site. These studies demonstrate the highly specific nature of hsc70/SGL binding and show, for the first time, that the lipid aglycone can alter the substitution position requirement for glycolipid recognition.

Abstract
The region(s) of hsp70 critical for sulfogalactolipid (SGL) recognition has been defined through deletion analysis and site-directed mutagenesis. Truncated polymerase chain reaction products of hsp70 generated N-terminal fragments of 43, 35, 29, and 22 kDa. The C terminus substrate-binding domain (28 kDa) was also expressed. The N-terminal ATPase domain (rP43) shared the binding specificity of hsp70, because only sulfogalactosyl ceramide and sulfogalactosyl glycerolipid were recognized by both TLC overlay and RELISA. The C-terminal domain showed no binding. SGL binding of rP29 and rP22 was severely reduced. The loss of SGL binding for rP35 by RELISA but not TLC overlay was considered as a function of receptor presentation. The truncation of rP43 to rP35 demonstrates that residues 318-387 (the base of the ATP binding cleft) are critical for high affinity SGL binding. Mutagenesis showed that Arg(342) and Phe(198) are crucial for this process. SGL binding, mediated by these conserved residues within the ATPase domain of hsp70, implies that this binding specificity is evolutionarily conserved.

Abstract
In this study, we determined the concentrations of acidic lipids, including cholesterol sulfate (CS), sulfatide and GM3 ganglioside, in human sera of non-pregnant state and during the course of pregnancy. In human sera of non-pregnant women, GM3 was present at a concentration of 8 nmol/ml and the concentrations of CS and sulfatides were less than 20% of that of GM3. The concentration of sulfatides in sera at the second trimester of gestation was decreased, but CS gradually increased from the first to the third trimester of gestation with a correlation coefficient of 0.66, and a correlation between the concentration of CS and weeks of gestation (p<0.01). CS was also contained in the placental villi, and its concentration increased from the first to the third trimester of gestation, suggesting that placental CS is one of the source of CS in the blood by shedding.

Abstract
Immunofluorescent studies with anti-2A antisera, raised specifically against a synthetic C-terminal peptide of native murine P70, the testes-specific cognate heat shock protein 70, demonstrated that the rat homologue of P70 is expressed on the surface of testicular cells. The murine hsp 70.2 gene, encoding P70, was cloned and expressed in Escherichia coli. The recombinant P70 (rP70) protein with a 6Xhistidine affinity tag at its amino terminus was purified from E. coli via nickel affinity column chromatography. Monoclonal anti-hsp70 antisera and anti-2A antisera cross-reacted with purified rP70. Binding of rP70 was specific for sulfogalactosylceramide (SGC) and sulfogalactosyglycerolipid (SGG). Binding was not inhibited by the sugar, galactose 3'sulfate, nor was binding observed to desulfated derivatives of SGC and SGG, to other negatively charged lipids or other sulfated lipids. Furthermore, rP70 bound to an SGC-column and was eluted only at high salt in combination with high pH. These results show rP70 to possess a specific sulfatide binding site. Since the biochemical properties and immunoreactivity of rP70 are indistinguishable from native P70 and SLIP1 (testicular sulfoglycolipid immobilized protein 1) rP70 can be employed to examine the role of hsp70-mediated sulfatide binding in fertilization.

Abstract
Cholesterol sulfate (CS) recently has been shown to be involved in signal transduction pathway. To evaluate its functional significance, we determined the concentration of CS, and the specific activities of cholesterol sulfotransferase and CS sulfatase in various tissues of rabbit, and compared them with the concentration of sulfoglycolipids in rabbit tissues. CS was present in the epithelia and mucosa, but not in the tunica muscularis, of the digestive tract, trachea, uterine endometrium and uterine cervix. It was also present in lung, spleen, kidney, prostate, skin, hair, and nail at relatively high concentrations. Its concentration in the uterine endometrium was nine times higher in pseudopregnant rabbits than in nonpregnant rabbits because of activation of cholesterol sulfotransferase and inhibition of CS sulfatase in the pseudopregnant rabbits. Sulfoglycolipids were not detected in the uterine endometria of either non-pregnant- or pseudopregnant rabbits. However, sulfoglycolipids were detected at relatively high concentrations in the cerebrum, cerebellum, stomach, duodenum, jejunum, testis, and kidney of rabbits and thus the tissues in which both sulfolipids were detected were the gastrointestinal tract and kidney. In the digestive tract, the concentration of CS decreased in the order esophagus, stomach, duodenum, and jejunum, but that of sulfatide increased in the same order, indicating distribution of CS in the squamous epithelium. In addition, both CS and sulfatide were detected in the serum. On the other hand, CS sulfatase activity was detected in all tissues examined, even in hair, from which the enzyme was liberated by brief sonication, and its highest specific activity was detected in the liver. The specific activity of cholesterol sulfotransferase varied among the tissues examined and was found to be significantly high in the esophageal epithelium and the uterine endometrium of pseudopregnant rabbit, indicating involvement of cholesterol sulfation in the formation of epithelium.

Abstract
OBJECTIVE Our purpose was to investigate the metabolic background of the expression of sulfoglycolipids in human endometrium during the luteal phase. STUDY DESIGN We investigated the expression of sulfoglycolipids by thin-layer chromatography immunostaining and the activities of galactosylceramide sulfotransferase and arylsulfatase A, which regulate the synthesis and degradation of sulfoglycolipid. In addition, arylsulfatase A messenger ribonucleic acid was studied by reverse transcriptase polymerase chain reaction. RESULTS Sulfoglycolipid expression showed a marked increase in the luteal phase but not in the follicular phase, whereas sialoglycolipids remained relatively constant. The increase of sulfoglycolipids was found to be due to 4.5-fold increased activation of sulfotransferase and a concurrent reduction of arylsulfatase A activity in the luteal phase. Arylsulfatase A messenger ribonucleic acid was detected in both phases and showed no significant changes. CONCLUSIONS These findings suggest that increased sulfoglycolipid expression in the luteal phase is due to the simultaneous regulation of sulfotransferase and arylsulfatase A, probably by sex steroid hormones.

Abstract
We have previously shown that several mycoplasma species associated with infertility bind specifically to sulfated glycolipids isolated from the mammalian reproductive tract. We now show that a germ cell-specific sulfoglycolipid binding protein (SLIP 1), which is a potent inhibitor of sperm/egg binding in vitro, is immunologically related to the heat shock protein(Hsp) 70 family of stress proteins and that Hsps are surface antigens in male germ cells. Our present data demonstrate that several mycoplasma and mammalian Hsps share this glycolipid binding specificity in vitro, and suggest that surface Hsps can function as adhesins which mediate sulfoglycolipid recognition in infectious disease and normal reproductive physiology.

Abstract
Cellular proliferation and differentiation in mammary gland are known to be significantly altered during pregnancy and subsequent lactation. To characterize the different stages of mammary gland during pregnancy and lactation, we analyzed the glycosphingolipid compositions in the mammary gland of DDD and ICR mice at several periods of pregnancy and lactation, and found that the ganglioside composition, but not neutral glycosphingolipids, was characteristically altered during the pregnancy and lactation periods. The concentrations of acidic glycosphingolipids, I3SO3-GalCer 1, GM3, GM1a, GM1b and GD1a, were reduced during the course of pregnancy and lactation. GD1 alpha (III6NeuAc alpha,IV3NeuAc alpha-Gg4Cer) was first detected at the mid-period of pregnancy (12 days of pregnancy for ICR mice), increased in concentration at the late-period of pregnancy (GD1 alpha concentration was 100 times higher at 18 days than that at 12 days of pregnancy), and was a major ganglioside comprising 60-70% of the total lipid-bound sialic acid in the mammary gland of ICR and DDD mice at the lactation period, indicating that expression of GD1 alpha is associated with the lactating mammary gland of mice. In fact, GD1 alpha was highly concentrated in the milk fat globule, in which it was a major component.

Abstract
Sulphatide has been found in rat islets of Langerhans and anti-sulphatide antibodies have been demonstrated in patients with insulin-dependent diabetes mellitus. Using a specific monoclonal antibody, Sulph I, directed against sulphatide, we investigated the in situ distribution of this glycolipid immunohistochemically; furthermore, the sulphatide concentration was determined in several organs and cells by thin-layer chromatography. The islets of Langerhans in all species examined, mouse, rat, pig, and monkey were intensively stained but exocrine tissue remained unlabelled. The sulphatide concentration in human islets was 150 +/- 46 pmol/100 islets. The only glycolipid-antigen detected was sulphatide. Regarding other tissues, sulphatide was found to be located in distal tubules in the kidney, peripheral nerves, distinct scattered spot-like structures in the choreoid layer of the eye, the ovum, and peripheral granulocytes. Sulph I injection in mice showed homing to kidney tubules, Lung, heart, liver, adrenal, spleen, lymph node and thymus were not stained by Sulph I. Thus, the distribution of sulphatide shows an association with organs known to be affected in diabetes, either initially or in late complications.

Abstract
Endometrium biopsic samples from women with cystic hyperplasia or adenocarcinoma were analysed by biochemical procedures to verify fluctuations in the acidic glycosphingolipid (sulphatide) concentration and arylsulphatase A (ASA) activity. Comparing the values of the considered parameters with those obtained in normal subjects, it was observed that ASA activity significantly increased in both pathologies; in contrast, sulphatide concentration underwent a non-significant decrease in hyperplasia and a statistically significant increase in neoplasia. The thin-layer chromatography (TLC) images revealed not only quantitative, but also qualitative differences in the lipid fractions. In fact, compared with controls, the sulphatides showed one more marked fraction in the neoplastic endometrium, and two fractions with different Rf values in the hyperplastic one. Moreover, two new unknown fractions also appeared in some subjects with cystic hyperplasia. The findings suggest the lipid metabolism undergoes considerable changes under the pathological conditions examined. The fluctuations observed, in particular, in the sulphatide concentration are believed to be related to changes in the biosynthetic and catabolic activities of the key enzymes directly involved in their metabolism, i.e. arylsulphatase A and sulphotransferase, which are regulated by sex hormones.

Abstract
Sulfate incorporation was studied in subcultured glandular epithelial cells of guinea-pig endometrium untreated or treated with 10(-8) M 17 beta-estradiol alone or associated with various concentrations of progesterone. In the cells treated with progesterone in association with 17 beta-estradiol, the maximum of the 35S-labelled cell-associated macromolecules failed to bind with an anion-exchange resin (53% of total radioactivity) and had a hydrophobic character. This fraction was separated as an aggregate when the cells were extracted with 4 M guanidine-HCl, and separated as a single component in the presence of Triton X-100, suggesting that it aggregates with cellular lipid. The guanidine-extracted material contained 23.5% proteoglycans. However, the bulk of the radioactivity was in the sulfated lipids (68-75%), essentially represented by cholesterol sulfate. In the progesterone-treated cells, the amount of cholesterol sulfate was significantly higher than in 17 beta-estradiol-treated or untreated cells (1.35-1.5-fold). Thus, the effect of progesterone is located on a lipophilic proteoglycan associated with cholesterol sulfate. These results are discussed in relation to the preparation of the endometrium for embryo implantation.

Abstract
In a series of experiments on the hormone-dependent molecular alteration in the human genital tract during the menstrual cycle, we focused our attention on a change in the negative charge due to the sulfuric acid- and sialic acid-containing glycosphingolipids. Although a ganglioside-derived negative charge was maintained in the cervical epithelia and uterine endometria at a relatively constant concentration throughout the luteal and follicular phases, I3SO3GalCer in both tissues characteristically increased in the luteal phase, indicating that the synthesis of I3SO3-GalCer in both tissues is associated with the menstrual cycle. However, I3SO3-GalCer in mucosae of the fallopian tubes in both phases was present in a concentration similar to that in the uterine endometrium in the luteal phase, and the change in the concentration did not associated with the menstrual cycle. On the other hand, although the concentrations of I3SO3-GalCer and II3NeuAc-LacCer, a major ganglioside, were similar in different regions, that is, the isthmus, ampulla and fimbriae of the fallopian tubes in the luteal phase, II3NeuAc-LacCer was present in a gradually increasing concentration from the isthmus to the fimbriae in the follicular phase, giving a gradually decreasing ratio of I3SO3GalCer to ganglioside from the uterus to the fimbriae. These findings indicate that the metabolism of sulfo- and sialoglycosphingolipids in the human genital tract is strictly controlled by estrogen and progesterone.

Abstract
Mycoplasma hominis, a human pathogen, has previously been observed to bind to sulfatide separated on thin-layer chromatograms. It has not been demonstrated, however, that the binding is not simply a nonspecific ionic interaction. The ability of a low-passage patient isolate of M. hominis to adhere to glycoconjugates other than sulfatide and the characteristics of its binding to sulfatide were studied. Mycoplasmas were found to bind strongly and specifically in a temperature- and dose-dependent manner to only sulfatide of all of the glycolipids and glycoproteins tested. The avidity and specificity of binding, as well as the ability to inhibit the interaction specifically, suggest that the receptors to which M. hominis binds, particularly in the human urogenital tract, from which it is frequently isolated, are primarily, if not solely, sulfated glycolipids.

Abstract
The effect of progesterone was studied on the sulfate entry in glandular epithelial cells of guinea-pig endometrium subcultured in bicameral chambers on matrix-coated filters in a chemically defined medium. At post-confluency (8 days of subculture), cells were treated with 10 nM estradiol alone or in association with various concentrations of progesterone. Optimal progesterone action was at a 16 h incubation time and a 10 nM hormonal concentration. Progesterone increased in a dose-dependent fashion the sulfate uptake specifically in glandular epithelial cells, preferentially from the basal surface. Progesterone effect on the sulfate uptake occurred only in estradiol-primed epithelial cells and was inhibited by the antiprogestin steroid RU-486. The progesterone-dependent increase in sulfate uptake was inhibited by the inhibitor of anion exchange, 4,4'-diisothiocyanostilbene-2,2'-disulfonic acid (DIDS). At physiological sulfate concentrations, progesterone essentially induces a high-affinity DIDS-sensitive transport system.

Abstract
Ca(2+)-dependent carbohydrate-binding proteins were purified from bovine kidney by two-step affinity chromatography on fetuin and heparin columns and subsequent anion-exchange high-performance liquid chromatography. On sodium dodecyl sulphate-polyacrylamide gel electrophoresis, the purified fraction gave two protein bands corresponding to proteins of relative molecular mass 33,000 (p33) and 41,000 (p41), respectively. Although the proteins had no haemogglutinating activities towards human and rabbit erythrocytes, their carbohydrate-binding activity was examined by a newly developed method using horseradish peroxidase (HRP) and/or biotin-labelled glycoconjugates as affinity probes. They could bind in a Ca(2+)-dependent manner to labelled fetuin and heparin in a specific and dose-dependent manner by solid-phase assay after immobilization on plastic plate surface. Inhibition assay of the binding revealed that N-acetylneuraminic acid is the most potent inhibitor of the proteins among the monosaccharides tested. Fucoidin and heparan sulphate most strongly inhibited the binding of the proteins to labelled heparin. Direct binding assay to acidic glycolipids prepared from bovine kidney showed that the proteins react with the ganglioside fraction but not with sulphatide [Gal(3-SO4) beta 1-1Cer]. These results indicated that the purified proteins have a significant affinity to charged oligosaccharides linking to glycoproteins, glycolipids and charged polysaccharides in a Ca(2+)-dependent manner.

Abstract
In the previous study, we found that sulfatide was characteristically expressed in the secretory phase of human uterine endometrium and that the metabolism of glycosphingolipids was strictly controlled by sex steroid hormones. Therefore, the neutral glycosphingolipid composition of human uterine endometrium in the proliferative and secretory phases was analyzed and was found to be characteristic in both phases. The major neutral glycolipids were GlcCer, LacCer, Gb3Cer and Gb4Cer. The concentrations of GlcCer, LacCer and Gb3Cer in the secretory phase were higher than those in the proliferative phase. Furthermore, on TLC, GlcCer, LacCer and Gb3Cer in the proliferative phase gave three bands, the 3rd band, which migrated to the lowest position, being much more predominant in the secretory phase. The individual band materials in both phases were purified by silica gel column chromatography, and their structures were analyzed by FABMS and GLC. The lower-migrating bands of GlcCer, LacCer and Gb3Cer were found to contain molecules with 2-hydroxy fatty acyl phytosphingosine, indicating that hydroxylation of the fatty acid and sphingosine moieties to give 2-hydroxy fatty acid- and phytosphingosine-containing glycosphingolipids, respectively, is induced selectively in the secretory phase on a change in the hormonal environment.

Abstract
The effect of progesterone on the available intracellular sulphate pool in subcultured glandular epithelial cells from guinea-pig endometrium is reported. Progesterone in concert with 17 beta-estradiol was shown to cause an increase in the available intracellular sulphate pool. The maximum effect was obtained for 10(-8) M and 10(-7) M progesterone. This effect of progesterone on the available intracellular sulphate pool essentially concerned the intracellular inorganic sulphate and was inhibited by the antiprogesterone steroid RU 486 (5 x 10(-7) M). Sulphate incorporation into the endometrial epithelial cells was suppressed by the inhibitor of anion transport diisothiocyanostilbene-2,2'-disulfonic acid (DIDS) and the protein synthesis inhibitor, cycloheximide. These results would suggest that a sulphate transport system may be involved in the accumulation of the intracellular sulphate, stimulated by progesterone. This phenomenon could be an early process in the preparation of the endometrium for implantation.

Abstract
1. Two clones (osmR-A and osmR-B) resistant to hyperosmotic media of 700 and 800 mosmol/l, respectively, were selected from Madin-Darby canine kidney (MDCK) cells. 2. When cultured in isosmotic medium (300 mosmol/l), the concentration of galactosyl sulfatide and lactosyl sulfatide in these hyperosmosis-resistant clones was 3.4-5.9 times higher than in the wild-type MDCK. The rate of incorporation of [35S]sulfate into sulfolipids of osmR-A and osmR-B was 1.9-6.7 times higher than MDCK. 3. The stimulation of incorporation into sulfolipids by hyperosmotic culture was completely inhibited by cycloheximide. The pulse-chase studies indicated decreased turnover rate of sulfolipids in osmR-A.
