In addition, the expression level of HSPH1 in lung cancer cell lines (A549, H1299, H1734, H520, Lewis cell, Beas-2b, H1975) was also examined by Western-blot, and it was found that compared with normal lung epithelial cells Beas-2b, the expression of HSPH1 was significantly higher in the remaining lung cancer cells, and the particular the difference was more obvious in both A549 and H520 cells (Figure 7B). This evidence concerns the gene HSPH1 and lung carcinoma.
