Glycosphingolipid GM2 Induces Invasiveness in Irradiation-tolerant Lung Cancer Cells.
Glycans, including glycosphingolipids, are broadly expressed in plasma membranes and play important roles in cell-cell interactions. Recently, it has been revealed that glycans participate in the regulation of malignant phenotypes of cancer cells, e.g. growth and invasion. However, their roles in irradiation-tolerant cancer cells have not yet been elucidated. In this study, we show that specific glycosphingolipids are highly expressed in invasive, irradiation-tolerant lung cancer cells. Particularly, the glycosphingolipid GM2 contributes to the development of an invasive phenotype in these lung cancer cells. Our results suggest that glycosphingolipids, including GM2, are implicated in the regulation of invasiveness in irradiation-tolerant lung cancer cells and may therefore serve as potential therapeutic targets for lung cancers following radiotherapy.Key words: glycosphingolipids, GM2, invasion, lung cancer cells, radiotherapy.
期刊介绍:
Cell Structure and Function is a fully peer-reviewed, fully Open Access journal. As the official English-language journal of the Japan Society for Cell Biology, it is published continuously online and biannually in print.
Cell Structure and Function publishes important, original contributions in all areas of molecular and cell biology. The journal welcomes the submission of manuscripts on research areas such as the cell nucleus, chromosomes, and gene expression; the cytoskeleton and cell motility; cell adhesion and the extracellular matrix; cell growth, differentiation and death; signal transduction; the protein life cycle; membrane traffic; and organelles.
