Extracellular roles for the molecular chaperone, hsp90

Abstract

In an Extra Views publication by Eustace and Jay (Cell Cycle 2004; 3:1096-1098), we reported that the co-chaperone Hsp70 was not found in the conditioned media of HT-1080 fibrosarcoma cells grown in culture (Figure 1). We have since discovered that this finding is in error. We reproducibly observe Hsp70 in HT-1080 conditioned media and believe the previous result was flawed due to a poor batch of antibody used for immunoblotting. We sincerely apologize for any confusion that this error might have caused.
