Insights

The Ras and Akt pathways regulate translation via the initiation factor eIF4E, crucial for cancer development. Targeting eIF4E offers a promising strategy for anticancer therapies.

Area of Science:

  • Molecular Biology
  • Oncology
  • Cell Biology

Background:

  • Historically, research focused on transcriptional regulation in oncogenesis.
  • Recent studies highlight the critical role of translational control in cancer.
  • Ras and Akt signaling pathways are key regulators of mRNA translation and cellular transformation.

Purpose of the Study:

  • To review the role of the translation initiation factor eIF4E in oncogenesis.
  • To elucidate how Ras and Akt signaling pathways influence translation and mediate cancer development.

Main Methods:

  • Literature review focusing on translational control mechanisms in cancer.
  • Analysis of the convergence of Ras/Akt pathways on eIF4E.
  • Examination of eIF4E's role in regulating malignancy-associated mRNAs.

Main Results:

  • eIF4E binds the 5'cap of mRNAs, controlling translation of key oncogenic transcripts.
  • eIF4E regulates mRNAs involved in polyamine synthesis, cell cycle, proto-oncogene activation, angiogenesis, growth, survival, invasion, and cell communication.
  • eIF4E activity is implicated in cell division, development, and programmed cell death.
  • Overexpression of eIF4E is observed in multiple human cancers.

Conclusions:

  • eIF4E-mediated translational control is pivotal in tumor formation and metastasis.
  • eIF4E's critical role in oncogenesis and its overexpression in cancers make it a significant therapeutic target.

Initiation of Translation02:33

Initiation of Translation

Initiating translation is complex because it involves multiple molecules. Initiator tRNA, ribosomal subunits, and eukaryotic initiation factors (eIFs) are all required to assemble on the initiation codon of mRNA. This process consists of several steps that are mediated by different eIFs.
First, the initiator tRNA must be selected from the pool of elongator tRNAs by eukaryotic initiation factor 2 (eIF2). The initiator tRNA (Met-tRNAi) has conserved sequence elements including modified bases at...

Improving Translational Accuracy02:07

Improving Translational Accuracy

Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...
Post-translational Translocation of Proteins to the RER01:27

Post-translational Translocation of Proteins to the RER

A sizable fraction of proteins destined for ER are first synthesized in the cell cytosol and then transported across the ER membrane–a process called post-translational translocation. Similar to cotranslationally translocated proteins, these proteins also use the Sec translocon complex to enter the ER lumen.
Targeting proteins to the ER
Hsp40 and Hsp70 chaperone molecules bind the translated proteins in the cytosol to prevent their folding. The chaperone binding helps to keep the signal...
Translation in Prokaryotes01:29

Translation in Prokaryotes

Prokaryote translation is a complex, highly coordinated process that converts genetic information from mRNA into functional proteins. It involves three stages: initiation, elongation, and termination, each facilitated by specific molecular components.Initiation of TranslationThe process begins with the assembly of the ribosomal subunits and initiation factors on the mRNA. In bacteria, the 30S ribosomal subunit recognizes the Shine-Dalgarno sequence in the mRNA, a conserved region upstream of...

Translation

Lesson: Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.
