چکیده
Thank you for submitting your manuscript for consideration to The EMBO Journal editorial office. I have now had the opportunity to read the manuscript carefully and also to discuss it in detail with the other members of our editorial team. Furthermore, I kindly asked an external advisor to independently assess your manuscript for its suitability here, which might explain the slight delay in getting back to you with an initial editorial decision. After this consultations, I am sorry to say that our evaluation was not a positive one, as we all had to conclude that we are unable to offer publication.

4E-BP1 is a target of Smad4 essential for TGFbeta-mediated inhibition of cell proliferation.
Assembly of the multi-subunit eukaryotic translation initiation factor-4F (eIF4F) is critical for protein synthesis and cell growth and proliferation. eIF4F formation is regulated by the translation-inhibitory protein 4E-BP1. While proliferation factors and intracellular pathways that impinge upon 4E-BP1 phosphorylation have been extensively studied, how they control 4E-BP1 expression remains u...
متن کاملChromatin, Gene, and RNA Regulation Contribution of HIF-1a in 4E-BP1 Gene Expression
The eukaryotic translation initiation factor 4E (eIF4E) is necessary for the translation of capped mRNAs into proteins. Cap-dependent mRNA translation can be however inhibited by the eIF4E-binding protein 1 (4E-BP1). The hypophosphorylated forms of 4E-BP1 indeed sequester eIF4E and thus block translation initiation and consequent protein synthesis. Different reports indicate that, in addition t...
متن کاملLAT-derived microRNAs in HSV-1 target SMAD3 and SMAD4 in TGF-β/Smad signaling pathway
Background: During its latent infection, HSV-1 produces only a miRNA precursor called LAT, which encodes six distinct miRNAs. Recent studies have suggested that some of these miRNAs could target cellular mRNAs. One of the key cell signaling pathways that can be affected by HSV-1 is the TGF-β/Smad pathway. Herein, we investigated the potential role of the LAT as well as three LAT-derived miRNAs ...
متن کاملNew insights into 4E-BP1-regulated translation in cancer progression and metastasis.
Remarkable progress has been made highlighting the importance of cap-dependent mRNA translation in cancer progression. 4E-BP1 is a translation initiation repressor by sequestering the mRNA cap-binding protein eIF4E and consequently inhibiting the translation of certain key oncogenic mRNAs encoding proteins for cell proliferation, survival, angiogenesis and malignancy. In most tumors, however, t...
متن کاملO-13: Phosphorylation of 4E-BP1 Promotes Translation at The Oocyte Spindle
Background: Fully grown mammalian oocyte utilizes transcripts synthetized and stored during earlier development. In the mouse oocyte there are three forms of cap-dependent translational repressors: 4E-BP1, 4E-BP2, and 4E-BP3. The dominant form, 4E-BP1, inhibits cap-dependent translation by binding to the eIF4E translation initiation factor. Hyperphosphorylation of 4E-BP1 disrupts this inhibitor...
