细胞凋亡是清除受损或不需要的细胞的重要过程。在这项研究中,我们提出了死亡受体介导的细胞凋亡的数学模型,以研究c-FLIP在控制细胞凋亡和存活之间的平衡中的作用。为了深入了解NF-kappa B介导的促生存途径如何影响我们的建模结果,我们在不考虑这种调节的情况下实施了简化模型。我们的模拟表明,c-FLIP可以作为关键的死亡或生命开关,这种开关行为是双稳态的、不可逆的和鲁棒的。我们引入了一个新的术语,概率凋亡,来描述细胞凋亡事件发生的可能性。该模拟系统是合理的,并可能提供一些有价值的临床指征异常凋亡相关疾病,如癌症。
Apoptosis is an essential process to get rid of injured or unwanted cells. In this study, we proposed a mathematical modeling for death receptor mediated apoptosis to investigate the role of c-FLIP in controlling the balance between apoptosis and survival. In order to get insight into how NF-kappa B mediated pro-survival pathway affects the outcome of our modeling, we implemented reduced models without taking such regulation into consideration. Our simulation revealed that c-FLIP could act as a pivotal death or life switch and this switch-like behavior is bistable, irreversible, and robust. We introduce a new term, probability apoptosis, to delineate the likelihood in occurrence of apoptosis events. This simulation system is plausible and may offer several valuable clinical indications for the abnormal apoptosis related disease, such as cancer.
