HSP90AA1 and neoplasm: In addition, upregulation of HSP90ɑ and translationally controlled tumor protein (TPT‐1) in both CAB and CAO patients, and upregulation of HSP70 in CAO patients compared to HS, is consistent with previous studies which reported their association with enhanced tumor invasiveness and malignancy.50, 51 In contrast, HSP70, HSP90α, and TPT‐1 were not detected in CAOAC subjects, possibly suggesting their chemosensitivity toward paclitaxel and carboplatin drug therapy.
