摘要： The use of natural substances derived from traditional Chinese medicine and natural plants as safe radiosensitizing adjuvants is a new trend for cancer radiotherapy. Ganoderma lucidum has been used as a traditional Chinese medicine with a history of more than 2000 years. Ganoderic acid T (GAT) is a typical triterpene of G. lucidum, which has strong cytotoxicity to cancer cells, but whether it has radiation sensitization effect has not been explored. In this work, we treated the HeLa cells with different concentrations of GAT before exposure to gamma-ray radiation and investigated its influence on the radiosensitivity. The cell viability, apoptosis rate, necoptosis rate, intracellular ATP level, cell cycle, the amount of H2AX and 53BP1, reactive oxygen species, and mitochondrial membrane potential were examined. Apoptotic, necroptotic, and autophagic biomarker proteins, including caspase 8, cytochrome c, caspase 3, RIPK, MLKL, P62, and LC3, were analyzed. As a result, we confirmed that with treatment of GAT, the gamma-ray radiation induced both apoptosis and necroptosis in HeLa cells, and with increase of GAT, the percentage ratio of necroptosis was increased. The involved pathways and mechanisms were also explored and discussed.
