内容記述 | In vivo biological effects induced by carbon-ion (C-ion) are still not fully understood. We examined gene expression changes for six mouse leg tumors of C3H/HeNrs mice using 44K oligo-microarrays at 6 hours (h), 1 day, and 3 days after C-ion irradiation with a single dose of 30 Gy. Gamma rays of 30 Gy and 50 Gy were used as a reference beam. In all six tumors, C-ion significantly changed the expression amounts of several tens of genes, including Cdkn1a, Ccng1, Ercc5, Mgmt, Cd80, and Polk at 6 h and 1 day, and Casp4, Tnfrsf6, Ikbke, Ifi202b, Fdps, and Ecm1 at 3 days. Expression changes of stress-responsive genes and cell communication-related genes lasted until 3 days. Expression changes of these genes in gamma-ray-treated samples were mostly similar or less than with C-ion, with large intertumor variance, while several genes, including Ikbke and Saa3, responded quite differentially from those irradiated by C-ions. Sequential immunohistochemical analysis of AurkA, Cdc20, and Cdkn1a revealed cell cycle/division arrest with mitotic catastrophe. Prolonged upregulation of stress-marker proteins and downregulation of cell-cycle promotion molecules provided evidence for the efficacy of this modality for local tumors. | |||||
