We then interrogated the mRNA expression of Hsp90 co-chaperones from two GBM clinical datasets, including cell division cycle 37 (CDC37), stress-induced phosphoprotein 1 (STIP1), and Hsp90 class B, demonstrating a clear upregulation of HSP90AA1 in each (Figure 1C). The gene discussed is STIP1; the disease is glioblastoma.
