报告摘要:Abstract

To assess the toxicity of various circadian patterns of anticancer drug delivery so as to enhance the efficiency of cancer chronotherapy, we need a model for the mammalian cell cycle. We developed two complementary approaches to cell cycle modeling. One is a detailed model for the cyclin/Cdk network driving the mammalian cell cycle. The second approach represents a stochastic automaton model for the cell cycle. Based on the sequential transitions between the successive phases G1, S (DNA replication), G2, and M (mitosis) of the cell cycle, the model allows us to simulate the distribution of cell cycle phases as well as entrainment by the circadian clock. We used the model to evaluate circadian patterns of administration of two anticancer drugs, 5-fluorouracil (5-FU) and oxaliplatin (l-OHP). The results indicate that the same temporal pattern of drug administration can have minimum cytotoxicity toward one cell population, e.g. of normal cells, and at the same time can display high cytotoxicity toward a second cell population, e.g. of tumor cells.  Thus the model allows us to uncover factors that may contribute to improve simultaneously the chronotolerance and chronoefficacy of anticancer drugs.
