Image-Guided Radiotherapy Targets Macromolecules through Altering the Tumor Microenvironment

2218 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

2200 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]

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

1070 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

1699 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

1633 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

1361 views | Jul 27 2017

Kanteti R et al. showed that a combination of crizotinib with BKM120 was highly synergetic in inhibiting MPM tumor growth. In conclusion our findings suggest that dual inhibition of PI3K and MET pathway is an effective strategy in treating MPM as compared to a single agent. [Read the Full Post]
