Abstract
Ovarian cancer is the most lethal gynaecological malignancy. It is commonly diagnosed at advanced stage when it has metastasised to the abdominal cavity and treatment becomes very challenging. While current standard therapy involving debulking surgery and platinum + taxane-based chemotherapy is associated with high response rates initially, the large majority of patients relapse and ultimately succumb to chemotherapy-resistant disease. In order to improve survival novel strategies for early detection and therapeutics against treatment-refractory disease are urgently needed. A promising new target against ovarian cancer is the sphingolipid pathway which is commonly hijacked in cancer to support cell proliferation and survival and has been shown to promote chemoresistance and metastasis in a wide range of malignant neoplasms. In particular, the sphingosine kinase 1-sphingosine 1-phosphate receptor 1 axis has been shown to be altered in ovarian cancer in multiple ways and therefore represents an attractive therapeutic target. Here we review the roles of sphingolipids in ovarian cancer progression, metastasis and chemoresistance, highlighting novel strategies to target this pathway that represent potential avenues to improve patient survival.

Abstract
Though glycosphingolipids have great potential as therapeutics for cancer, HIV, neurodegenerative diseases and auto-immune diseases, both extensive study of their biological roles and development as pharmaceuticals are limited by difficulties in their synthesis, especially on large scales. Here we addressed this restriction by expanding the synthetic scope of a glycosphingolipid-synthesizing enzyme through a combination of rational mutagenesis and directed evolution with an ELISA-based screening strategy. We targeted both a low-level promiscuous substrate activity and the overall catalytic efficiency of the catalyst, and we identified several mutants with enhanced activities. These new catalysts, which are capable of producing a broad range of homogeneous samples, represent a significant advance toward the facile, large-scale synthesis of glycosphingolipids and demonstrate the general utility of this approach toward the creation of designer glycosphingolipid-synthesizing enzymes.

Abstract
Ceramide and other sphingolipid mediators have emerged as a novel class of lipid second messengers in cell signaling. We assessed the effect of C(2)-ceramide (a membrane permeable analog of ceramide) on spontaneous and agonist-induced contractile responses of uterus, isolated from 19-day pregnant rats. Ceramide (3, 10 microM) moderately, but significantly inhibited the amplitude of spontaneous rhythmic contractions. However, a variable effect was seen on agonist-induced contractions. While 5-HT-induced contractions were markedly inhibited at 3 and 10 microM ceramide, oxytocin and carboprost (a PGF(2)alpha analogue)-induced contractions were not affected by the sphingolipid. Ceramide (10 microM) also markedly inhibited CaCl(2)-induced contractions elicited in K(+)-depolarized tissues. Further, in rabbit portal vein myocytes, which display robust L-type calcium channel current, ceramide inhibited the I(Ba) in a dose-dependent manner. Therefore, it is suggested that the inhibitory effect of ceramide on uterine contractility may involve a decrease in the influx of Ca(2+) through voltage-dependent L-type Ca(2+) channels, such that contractile responses that are primarily dependent on extracellular Ca(2+), like rhythmic and serotonin contractions, were inhibited by ceramide. Further study is required to establish the role of endogenous ceramide and other sphingolipids in regulating uterine tone during gestation and at term.

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.
