HSP90 gene expression profile (mRNA level) across all tumor samples and normal tissues were analyzed in GEPIA and these results were shown in bar plot (A) and dot plot (B) separately. (C) Expression levels of HSP90 gene in rectal cancers (READ), colon cancers (COAD) and normal tissues were analyzed using TCGA data. The statistical analysis was performed by using the Student's t test. *P < 0.05.
