Previously, we found that Hsp90-beta was higher in H446 cells (1.72 times) and A549 cells (2.19 times) than 16-HBE cells [18] and that increase of Hsp90-beta correlated with postoperative survival time and lymph node metastasis of lung cancer patients [11]. Here, HSP90AB1 is linked to metastatic malignant neoplasm in the lymph nodes.
