Heat-shock proteins (HSPs) —also phosphorylating AKT—were upregulated in CLs and normal-like TN tumours; some of them—HSP90AA1 and HSP90B1—were also upregulated in basal-like TN tumours, and one—HSP90B1— was upregulated across all sample groups. The gene discussed is HSP90B1; the disease is neoplasm.
