Heat Shock Proteins (HSP) are expressed at high levels in cancer and form a fostering environment essential for tumor development. We have reviewed the recent data in this area, concentrating mainly on Hsp27, Hsp70 and Hsp90. The overriding role of the HSPs in cancer is to stabilize the active functions of overexpressed and mutated cancer gene. Elevated HSPs are thus required for many of the traits that underlie the morbidity of cancer, including increased growth, survival and formation of secondary cancers. In addition, HSPs participate in the evolution of cancer treatment resistance. HSPs are also released from cancer cells and influence malignant properties by receptor- mediated signaling. Current data strongly support efforts to target HSPs in cancer treatment.
