In addition, mRNA expression of HSP90 family members in TCGA ACC cohort was statistically significantly and linearly correlated with MKI67 (cell proliferative index)24 and CTNNB1 (β-catenin)25, two well-known genes associated with poor prognosis in human ACC (Table 1). Here, HSP90AB1 is linked to adrenal cortex carcinoma.
