This Teaching Resource provides lecture notes, slides, and a problem set for introducing graduate-level students to computational biology through a simple mathematical model of the cell cycle. The model simulates interactions between cyclin B and cyclin-dependent kinase 1, proteins that together form the mitosis-promoting factor (MPF), which initiates the processes leading to mitosis. The lecture begins with a biological background describing the importance of MPF for mitosis, the components of MPF, and the changes in cellular MPF observed during different phases of the cell cycle. The model is compared with newer, more mechanistically detailed models of the same process, which allows for a discussion of the insights that can be gained even from simplified models. The lecture concludes with a demonstration of how this model can be implemented in the scientific programming language MATLAB and includes a problem set.
本教学资源提供了讲义、幻灯片和习题集,通过一个简单的细胞周期数学模型,向研究生介绍计算生物学。该模型模拟了细胞周期蛋白 B 和细胞周期蛋白依赖性激酶 1 之间的相互作用,这两种蛋白共同构成了有丝分裂促进因子(MPF),它启动了导致有丝分裂的过程。讲座首先介绍了生物学背景,描述了 MPF 对有丝分裂的重要性、MPF 的组成以及在细胞周期的不同阶段观察到的细胞 MPF 的变化。该模型与同一过程的更新、更具机械细节的模型进行了比较,从而可以讨论即使从简化模型中也可以获得的见解。讲座最后演示了如何在科学编程语言 MATLAB 中实现该模型,并包含了习题集。
