Bag3, a nucleotide exchange factor of the heat shock protein Hsp70, has been
implicated in cell signaling. Here, we report that Bag3 interacts with the SH3
domain of Src, thereby mediating the effects of Hsp70 on Src signaling. Using
several complementary approaches, we established that the Hsp70-Bag3 module is a
broad-acting regulator of cancer cell signaling by modulating the activity of the
transcription factors NF-?B, FoxM1, Hif1?, the translation regulator HuR, and the
cell-cycle regulators p21 and survivin. We also identified a small-molecule
inhibitor, YM-1, that disrupts the Hsp70-Bag3 interaction. YM-1 mirrored the
effects of Hsp70 depletion on these signaling pathways, and in vivo
administration of this drug was sufficient to suppress tumor growth in mice.
Overall, our results defined Bag3 as a critical factor in Hsp70-modulated
signaling and offered a preclinical proof-of-concept that the Hsp70-Bag3 complex
may offer an appealing anticancer target.
