HSPH1 and lung cancer: 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).
