On the contrary, in the malignant tumor group, that of HSP27 and HSP60 both decreased to 65.00% (26/40), and those of HSP70, HSP86 and HSP84 increased to 100% (40/40), 100% (40/40) and 90% (36/40), respectively (P=0.006, 0.581, 0.002, 0.001 and 0.029, respectively). This evidence concerns the gene HSP90AB1 and cancer.
