Furthermore, in order to seek for potential anti-tumor drugs targeting HSP90B1-associated genes, we conducted analysis from the Connectivity Map (CMap) database and identified 57 HSP inhibitors [14], which demonstrated proliferative-suppressive effects on cancer cell lines such as SKB, A375, PC3, and SW480 (connectivity score < 0) (Suppl. This evidence concerns the gene HSP90B2P and cancer.
