Ovarian cancer is the fourth most common cancer in women in the Western world. In a pilot scale study, we highlight changes in the total serum glycome of patients with advanced ovarian cancer that might shed insight into disease pathogenesis. These changes include increases in levels of core fucosylated, agalactosyl biantennary glycans (FA2) and sialyl(More)
Aberrant glycosylation on glycoproteins that are either presented on the surface or secreted by cancer cells is a potential source of disease biomarkers and provides insights into disease pathogenesis. N-Glycans of the total serum glycoproteins from advanced breast cancer patients and healthy individuals were sequenced by HPLC with fluorescence detection(More)
BACKGROUND Metastatic breast cancer (MBC) is currently an incurable condition that is primarily treated with palliative measures. Isolation of circulating tumor cells (CTCs) from the peripheral blood of these patients provides a predictive prognostic indicator, independent of the type of therapy, site of occurrence and biological characteristics of the(More)
Sialuria is an inborn error of metabolism characterized by coarse face, hepatomegaly and recurrent respiratory tract infections. The genetic defect in this disorder results in a loss of feedback control of UDP-N-acetylglucosamine 2-epimerase/N-acetylmannosamine-kinase by CMP-N-acetylneuraminic acid (CMP-NeuAc) resulting in a substantial overproduction of(More)
One of the most urgent requirements in breast cancer is the development of a blood-based test for early detection and prognosis. Previously published results found a significant difference between specific glycan levels in patients with advanced breast cancer and healthy controls. The aim of this investigation was to address a more clinically relevant(More)
