Bcl-2 phosphorylation confers resistance on chronic lymphocytic leukaemia cells to the BH3 mimetics ABT-737, ABT-263 and ABT-199 by impeding direct binding

1242 views | Aug 03 2017

Song T et al. suggested that a structural alteration in the BH3-binding groove was induced by phosphorylation of Bcl-2. Our data also provided a framework to overcome resistance of CLL cells to the ABT compounds by combining pBcl-2 kinase inhibitors with the ABT compounds. [Read the Full Post]

Image-Guided Radiotherapy Targets Macromolecules through Altering the Tumor Microenvironment

2152 views | Aug 01 2017

Appelbe OK et al. suggest repurposing image-guided radiotherapy as a tool to guide cancer nanomedicine delivery, enhancing local control for primary tumors and metastatic disease while limiting systemic toxicity. [Read the Full Post]

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

2136 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

1193 views | Jul 31 2017

Noguchi K et al. suggests that AKT3 could repress the antiproliferative effects of AURKi, with a novel activity particularly suppressing the aneuploidy induction. [Read the Full Post]

Sunitinib Treatment Enhances Metastasis of Innately Drug-Resistant Breast Tumors

Wragg JW et al. unraveled specific features of antiangiogenic resistance, with potential therapeutic implications. [Read the Full Post]

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

1035 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.

Long-term treatment with EGFR inhibitor erlotinib attenuates renal inflammatory cytokines but not nephropathy in Alport syndrome mouse model

1637 views | Jul 28 2017

Omachi K et al. suggested that EGFR signaling is upregulated in kidney, but although inhibiting this signaling pathway suppressed renal inflammatory cytokines, it did not ameliorate renal dysfunction in AS mouse model. [Read the Full Post]

miR-17-5p down-regulation contributes to erlotinib resistance in non-small cell lung cancer cells

1580 views | Jul 28 2017

Zhang W et al. indicated that miR-17-5p down-regulation contributes to erlotinib resistance of NSCLC by modulating its target genes such as EZH1 and plasma miR-17-5p might be a potential biomarker of erlotinib response in NSCLC patients. [Read the Full Post]

PI3 Kinase Pathway and MET Inhibition is Efficacious in Malignant Pleural Mesothelioma
