  7. Phopholipase c - 1 ( plc - 1 ) is widely known to play an important role in regulating cell proliferation and differentiation, development of the organisms, cell transformation and oxidative stress. till now, the mechanism how phopholipase c - 1 acts can not be thoroughly illustrated, nor has the interaction between plc - 1 pathway and other signal pathways been systematically reported. this research chose 2 - de + ms as the basic method from all kinds of proteomics strategies and compared the total protein expression map of mef genetically deficient in plc - 1 ( plc - 1 - / - ) to that of wild type mef ( plc - l + / + ) aimed to find some protein spots differentially expressed, thus we can discuss the impact of knockout of plc - 1 on signal transduction initiated by growth factors such as egf comprehensively. in this way, we can study the biological function of plc - 1 and mechanism of plc - 1 pathway indirectly, which will contribute a lot to further analysis

    鑒于plc - 1發揮上述作用的機制尚未完全闡明， plc - 1通路與其他信號通路間的交聯和代償尚無系統報道，又因為以往的研究方法不夠全面，本研究以野生型小鼠胚胎成纖維細胞（ plc - 1 ~ （ + / + ） ）和缺失磷脂酶c - 1的小鼠胚胎成纖維細胞（ plc - 1 ~ （ - / - ） ）為研究模型，在眾多蛋白組學策略中選擇了雙向電泳+質譜（ 2 - de + ms ）作為研究手段，通過對比表皮生長因子（ egf ）刺激24小時後上述兩種細胞的總蛋白質表達差異，全面地探討敲除plc - 1對生長因子誘導的信號傳遞的影響，從而間接研究plc - 1生物學作用、信號傳遞機制及其代償情況，為后續的深入研究打下基礎。
