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

890 views | Jul 17 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.

Liu R et al. conclude that the endogenous EPO/EPOR signaling pathway may contribute to the protective effects of ALA in the retina after ONC injury. [Read the Full Post]

The RNA-Binding Proteins Zfp36l1 and Zfp36l2 Enforce the Thymic β-Selection Checkpoint by Limiting DNA Damage Response Signaling and Cell Cycle Progression

1623 views | Jul 16 2017

Vogel KU et al. showed that in addition to controlling the timing of proliferation at β-selection, posttranscriptional control by Zfp36l1/l2 limits DNA damage responses, which are known to promote thymocyte differentiation. Zfp36l1/l2 therefore act as posttranscriptional safeguards against chromosomal instability and replication stress by integrating pre-TCR and IL-7 signaling with DNA damage and cell cycle control.
