HSP90AA1 and non-small cell lung carcinoma: We found that treatment with HSP70 inhibitor (MKT-077) (Figure 2F, 2H) or HSP90 inhibitor (17-AAG) (Figure 2G, 2I) significantly reduced the size and the number of spheres (Figure 2F-G) and the expression of CSC markers and HSP70/HSP90 client proteins (Figure 2H-I) in the indicated NSCLC cells.
