This approach is not novel since inhibitors of proteasomes, autophagy, and the Hsp90 chaperone are already employed in clinics, but the idea of our research was to destroy the Hsp70-based chaperonic system in particular, which is known to regulate the most important processes in a tumor cell by binding occasionally (or not occasionally) a variety of protein targets [35]. Here, HSPA1A is linked to neoplasm.
