内容記述
Growing evidence suggests that low-LET radiation can paradoxically promote tumor invasion and metastatic processes, however, there are limited reports concerning the effect of high-LET radiation on the invasiveness and migration of tumor cells, and the molecular mechanism remain largely unknown. Here, we found that carbon ions and gamma radiation can both induce a converse effect on cellular migration and invasion in HCT116 and DLD-1 cells, and this may be related to the opposite EMT process in these two cell lines, which are regulated by different phosphorylation of GSK3β protein after radiation.
