HSP90AA1

Across TCGA pan-cancer cohorts, HSP90AA1 mass-spec protein differs between tumor and matched normal tissue in 7 of 18 cancer types tested, making tumor–normal expression one of HSP90AA1’s most consistent transcriptional readouts.

The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where HSP90AA1 mass-spec protein is more highly expressed in tumor relative to normal tissue. In most cancer types HSP90AA1 is over-expressed in tumor, although a few such as CCRCC show the opposite, repressed pattern.

HNSC, CCRCC, and COAD are the cancer types where HSP90AA1 tumor–normal differential expression is most reproducible.

mass-spec protein tumor vs normal associations by lineage

Ranked by sampling consensus. Fold-change is the tumor-versus-normal difference in HSP90AA1 mass-spec protein (log₂); positive values indicate higher expression in tumor. p-values are from the differential-expression test.
