Chemical Synthesis of the Tumor-Associated Globo H Antigen.
A derivative of the tumor-associated globo H antigen, a complex hexasaccharide, was synthesized by a convergent and efficient [3+2+1] strategy using various glycosylation methods. All glycosylation reactions afforded good to excellent yields and outstanding stereoselectivity, including the installation of cis α-linked D-galactose and L-fucose. The longest linear sequence for this synthesis was ...
متن کاملCarbohydrate microarray for profiling the antibodies interacting with Globo H tumor antigen.
Understanding the specificity of cell-surface carbohydrates interaction with antibodies and receptors is important for the development of new therapeutics and high-sensitivity diagnostics. This approach is, however, limited to the availability of natural and truncated sequences of the oligosaccharides and the sensitivity of the assay system. Reported here is the synthesis of the cancer antigen ...
متن کاملStage-specific embryonic antigen-4 is expressed in basaloid lung cancer and associated with poor prognosis.
Basaloid carcinoma represents a rare variant of nonsmall cell lung cancer (NSCLC), which has shown a poor prognosis in a number of studies. Although it is considered to derive from a pluri- or multipotent pulmonary stem cells, little is known about the expression and clinical significance of stem cell antigens in this variant. Stage-specific embryonic antigen-4 (SSEA-4) was analysed by immunohi...
متن کاملAge Specific Reference Levels of Serum Prostate-Specific Antigen, Prostate Volume and Prostate Specific Antigen Density in Healthy Iranian Men
Background: It is relevant to highlight that there is not a precise and perfect report on either 95 percentile value (upper limit of normal range) or on appropriate reference intervals for serum PSA in Iranian population. Objective: To determine age-specific reference ranges for serum prostate-specific antigen (PSA) concentration and PSA density (PSAD) and prostate volumes in a population of he...
متن کاملBreast and abdominal adipose multipotent mesenchymal stromal cells and stage-specific embryonic antigen 4 expression.
We assessed human mesenchymal stem cells (MSCs) harvested from breast and abdominal adipose tissues enriched in embryonic stage-specific antigen (SSEA-4) expression for osteogenic and adipogenic differentiation in comparison to a mixed cell population. Human adipose was obtained from abdominal and breast tissues of females undergoing gastric bypass and breast reduction, respectively. SSEA-4-exp...
