Y-632 inhibits heat shock protein 90 (Hsp90) function by disrupting the interaction between Hsp90 and Hsp70/Hsp90 organizing protein, and exerts antitumor activity in vitro and in vivo

2750 views | Aug 01 2017

Wang W et al. believe that Y-632, acting as a novel small-molecule inhibitor of the Hsp90-Hsp70/Hsp90 organizing protein complex, has great potential to be a promising Hsp90 inhibitor for cancer therapy, such as for imatinib-resistant leukemia. [Read the Full Post]

Functional Effects of AKT3 on Aurora Kinase Inhibitor-induced Aneuploidy

Activation of EIF4E by Aurora Kinase A Depicts a Novel Druggable Axis in Everolimus-Resistant Cancer Cells

1531 views | Jul 30 2017

Katsha A et al. indicated that AURKA plays an important role in the activation of EIF4E and cap-dependent translation. Targeting the AURKA-EIF4E-c-MYC axis using alisertib is a novel therapeutic strategy that can be applicable for everolimus-resistant tumors and/or subgroups of cancers that show overexpression of AURKA and activation of EIF4E and c-MYC.
