摘要：

Heat shock proteins (Hsp) 70 and Hsp 40 are stress proteins that cooperate as chaperones in mammalian cells. We determined the expression of Hsp 70 and Hsp 40 in 81 gastric cancers. Immunoreactivities to Hsp 70 and Hsp 40 were detected in 67.9 and 22.2% of tumors, respectively. Immunohistochemical analysis showed enhanced Hsp 70 and Hsp 40 expression in gastric tumor tissue, relative to the surrounding normal tissue. Overexpression of Hsp 70 and Hsp 40 was also confirmed by immunoblotting. Among various clinicopathological parameters, low histopathological differentiation was associated with reduced expression of both proteins. (C) 2003 Elsevier Ireland Ltd. All rights reserved.
