Clinical Responses and Prognostic Indicators of Concurrent Chemoradiation for Non-small Cell Lung Cancer.

Purpose: To evaluate treatment outcomes and prognostic factors in non-small cell lung cancer (NSCLC) patients treated with concurrent chemoradiation.

Materials And Methods: From January 2005 to June 2009, 51 patients were treated with concurrent chemoradiation for 3 different aims: locally advanced stage III, locally recurrent disease, and postoperative gross residual NSCLC. Median age was 63 years.

CD36 signaling inhibits the translation of heat shock protein 70 induced by oxidized low density lipoprotein through activation of peroxisome proliferators-activated receptor gamma.

Oxidized LDL (OxLDL), a causal factor in atherosclerosis, induces the expression of heat shock proteins (Hsp) in a variety of cells. In this study, we investigated the role of CD36, an OxLDL receptor, and peroxisome proliferator-activated receptor gamma (PPARgamma) in OxLDL-induced Hsp70 expression. Overexpression of dominant-negative forms of CD36 or knockdown of CD36 by siRNA transfection increased OxLDL-induced Hsp70 protein expression in human monocytic U937 cells, suggesting that CD36 signaling inhibits Hsp70 expression.
