    細胞生長受到外部 growth factor 或細胞內部經 tyrosine kinase 的 signaling transduction 等調控,平常受到良好控制,當相關基因突變導致 growth factor 或tyrosine kinase 失控時,growth factor大量表現或 tyrosine kinase 不斷活化結果可能誘導細胞變成tumor,而這些突變後導致失控的gene就是proto-oncogenes,這時候你就要去找啥東東突變會導致 growth factor 或其 receptor 大量表現,或是啥種tyrosine kinase 突變會導致細胞走向 tumorigenesis
