信号级联放大-
细胞内游离Ca2+升高，激活一些蛋白磷酸酶，使底物蛋白磷酸化，将外界信号级联放大，进入核内，影响DNA复制，导致细胞恶变及肿瘤细胞的增殖分化。
The increasing of intracellular free Ca2 + active some protein phosphatase , thereby , affected cell DNA replication , leading to cell malignant transformation and tumor cell proliferation and differentiation .

c-fos作为即刻早期基因的一种，编码的Fos蛋白组成了其他许多基因的转录调控因子，因而可将外界信号级联放大，造成细胞长期的生理功能改变。
C fos , one of the immediate early genes , encodes Fos , which appears to modulate the express of more downstream genes and attribute to long term changes in cellular function .
