英文摘要	The molecular mechanisms underlying the biological effects of carbon ions are unclear. The aim of this study was to explore the Wnt/beta-catenin pathway in regulating carbon ion (C-12(6+)) radiation-induced cellular toxicity. HLY78 is a Wnt-specific small molecular modulator, whose effects on C-12(6+) radiation-induced damage are mostly unknown. HLY78, in combination with C-12(6+) radiation was investigated on HeLa cell viability, cell cycle progression, DNA damage, and the expression of apoptotic and Wnt-related proteins. C-12(6+) radiation suppressed cell viability in a time-dependent manner, whereas the addition of HLY78 to cells significantly reduced this stress. Moreover, after irradiation with C-12(6+), HeLa cells exhibited increased cell apoptosis, G2/M phase arrest, and a number of gamma-H2AX foci. However, Wnt signaling activation alleviated these effects. Furthermore, when compared with the radiation alone group, supplementation with HLY78 markedly increased the expression of anti-apoptotic and Wnt-related proteins, and significantly decreased the expression of apoptotic proteins. The present results indicated that activation of the Wnt/beta-catenin signaling pathway by HLY78 reduced C-12(6+) radiation-induced HeLa cell dysfunction, suggesting that the Wnt/beta-catenin signaling pathway plays an important role in regulating C-12(6+) radiation-induced cellular toxicity in HeLa cells.
