酸介导肿瘤侵袭的PDE-ODE模型的全局稳定性

Global Stability of a PDE-ODE model for acid-mediated tumor invasion

Fang li, Zheng-an Yao, Ruijia Yu

摘要:

本文研究了一类基于酸介导入侵假说的一般反应扩散模型的全局动力学性质,该假说是Warburg效应的一个候选解释。该模型的一个关键特征是肿瘤细胞的密度受限的肿瘤扩散项,这可能导致抛物型方程的退化。我们的理论结果表征了健康细胞和肿瘤细胞的耐酸性和相互竞争对肿瘤进展的长期影响,即,是健康细胞与肿瘤细胞共存还是肿瘤细胞在肿瘤侵袭后占优势。该方法依赖于合适的李雅普诺夫泛函和上/下解的建设。

英文摘要:

In this paper, we study the global dynamics of a general reaction-diffusion model based on acid-mediated invasion hypothesis, which is a candidate explanation for the Warburg effect. A key feature of this model is the density-limited tumor diffusion term for tumor cells, which might give rise to the degeneracy of the parabolic equation. Our theoretical results characterize the effects of acid resistance and mutual competition of healthy cells and tumor cells on tumor progression in the long term, i.e., whether the healthy cells and tumor cells coexist or the tumor cells prevail after tumor invasion. The approach relies on the construction of suitable Lyapunov functionals and upper/lower solutions.
