K-RAS基因突变广泛存在于非小细胞肺癌中。与肺癌的其他突变相比,这些药物不能有效地靶向突变的K-RAS。然而,癌细胞的有丝分裂很容易受到外界干扰。我们先前的研究表明,电磁场(MFS)可以抑制细胞增殖。本文以A549细胞为研究对象,考虑MFS对细胞增殖的影响,建立了细胞增殖模型。此外,用有限差分法对A549细胞增殖模型的参数进行了回归,并用数值模拟进行了验证。根据计算,A549细胞的密度反映了光学显微镜测量数据的趋势。这种方法不仅有助于揭示MFS对癌细胞的作用机制,而且为预测磁刺激对癌症的抑制作用提供了一种新的方法。
Mutation of the K-Ras gene has been widely found in non-small cell lung cancer. Compared with other mutations of lung cancer, the drugs cannot effectively target mutant K-Ras. However, the mitosis of cancer cells is vulnerable to external interference. Our previous study showed that electromagnetic fields (MFs) could suppress cell proliferation. In this article, a cell proliferation model based on the A549 cell line was established while considering the effects of MFs. In addition, the parameters of the A549 cell proliferation model were regressed by the finite difference method and verified by numerical simulation. Based on the calculations, the density of the A549 cells reflects the trend of measured data from optical microscopy. This approach not only helps reveal the mechanism of MFs on cancer cells but also suggests a new way to predict the effects of magnetic stimulation on cancer inhibition.
