Abstract
A low-oxygen (hypoxia) tumor microenvironment can facilitate chemotherapy and radiation therapy resistance in tumors and is associated with a poor prognosis. Hypoxia also affects PCa (prostate cancer) phenotype transformation and causes therapeutic resistance. Although O-glycans are known to be involved in the malignancy of various cancers under hypoxia, the expression and function of O-glycans in PCa are not well understood. In this study, the saccharide primer method was employed to analyze O-glycan expression in PCa cells. Results showed that the expression of sTn antigens was increased in PCa cells under hypoxia. Furthermore, it was found that ST6GalNAc1, the sTn antigen synthase gene, was involved in the migration-proliferation dichotomy and drug resistance in PCa cells under hypoxia. The results of this study will contribute to the development of novel diagnostic markers and drug targets for PCa under hypoxia.
期刊介绍：
Glycoconjugate Journal publishes articles and reviews on all areas concerned with:
function, composition, structure, biosynthesis, degradation, interactions, recognition and chemo-enzymatic synthesis of glycoconjugates (glycoproteins, glycolipids, oligosaccharides, polysaccharides and proteoglycans), biochemistry, molecular biology, biotechnology, immunology and cell biology of glycoconjugates, aspects related to disease processes (immunological, inflammatory, arthritic infections, metabolic disorders, malignancy, neurological disorders), structural and functional glycomics, glycoimmunology, glycovaccines, organic synthesis of glycoconjugates and the development of methodologies if biologically relevant, glycosylation changes in disease if focused on either the discovery of a novel disease marker or the improved understanding of some basic pathological mechanism, articles on the effects of toxicological agents (alcohol, tobacco, narcotics, environmental agents) on glycosylation, and the use of glycotherapeutics.
Glycoconjugate Journal is the official journal of the International Glycoconjugate Organization, which is responsible for organizing the biennial International Symposia on Glycoconjugates.
