Detect the change of the Expression of oncoprotein on the Chinese hamster lung cells (V79 cells) which effect with two main district of China and four alternative chrysotile fiber to investigate the factors of lung cancer. V79 cells were exposed to the suspension of Chrysotile and its substitute with different powder content, the survival rate of cells was monitored by MTT. After 48 h, the location, distribution and expression of Survivin, Cap43, Bcl-2, p16 and p53 in V79 cell were examined by immunohistochemistry and compared. In the six kinds of powder, the inhibition of rockwool on the growth of cells was weakest, the inhibition of Chrysotile from Xinkang Sichuan and Southern Shanxi on the growth of cells was strongest. Chrysotile from Xinkang Sichuan, Chrysotile from Southern Shanxi, glass fiber, ceramic fiber, rockwool and wollastonite had a certain influence on the survival rate of V79 cells. As the concentration of powder increased the survival rate of cells decreased, which showed dose-effect relationship. The expression of Survivin, Cap43 and Bcl-2 was upregulated and the expression of P16 and P53 was downregulated in V79 cells, which was obviously in the powder suspension of Chrysotile from Southern Shanxi and Xinkang Sichuan and glass fiber. The expression was mainly in cytoplasm. The influence of different kind of powder on the cells differed in degree. Chrysotile and its substitute can induce the development of cancer by upregulating the expression of Survivin, Cap43 and Bcl-2 and downregulating the expression of p16 and p53.
