乳腺癌是女性中最常见的癌症类型。了解乳腺癌的微环境以及细胞和细胞因子之间的相互作用将为患者提供更好的治疗方法。在这项研究中,我们开发了一个数据驱动的数学模型来研究乳腺癌发生过程中关键细胞和细胞因子的动态变化。我们使用肿瘤的基因表达谱来估计每个免疫细胞和基于他们的免疫模式的患者组的相对丰度。动力学结果显示细胞和分子之间复杂的相互作用,敏感性分析强调巨噬细胞和脂肪细胞对癌细胞生长的直接影响。此外,我们观察到了干扰素对肿瘤细胞增殖的双重作用,既可以直接抑制癌细胞,也可以通过增加CD8+T细胞的细胞毒作用。
Breast cancer is the most prominent type of cancer among women. Understanding the microenvironment of breast cancer and the interactions between cells and cytokines will lead to better treatment approaches for patients. In this study, we developed a data-driven mathematical model to investigate the dynamics of key cells and cytokines involved in breast cancer development. We used gene expression profiles of tumors to estimate the relative abundance of each immune cell and group patients based on their immune patterns. Dynamical results show the complex interplay between cells and molecules, and sensitivity analysis emphasizes the direct effects of macrophages and adipocytes on cancer cell growth. In addition, we observed the dual effect of IFN- on cancer proliferation, either through direct inhibition of cancer cells or by increasing the cytotoxicity of CD8+ T-cells.
