Heatmap of subcluster using endoplasmic reticulum stress‐related genes (58 probe sets), whose expressions were all changed by treatment with the four stress‐inducing agents. The row names are gene symbols of 58 probe sets, which were converted using the NetAffx database, NA32, supplied by Affymetrix. Two main clusters of upregulated genes were named “class 1” and “class 2” genes. 17‐AAG, 17‐N‐allylamino‐17‐demethoxygeldanamycin.
