Summary
Cancer progression involves altered translational control, where specific mRNA networks are modulated, not just overall protein synthesis. Understanding this translational specificity offers new therapeutic targets for cancer treatment.
Area of Science:
- Molecular Biology
- Oncology
- Genetics
Background:
- Aberrant translational control is a hallmark of cancer, driving initiation and progression.
- Oncogenic pathways induce significant translational reprogramming, impacting specific mRNA networks crucial for cellular transformation.
- Ribosomopathies, resulting from mutations in ribosome components, contribute to pathological features and cancer susceptibility.
Purpose of the Study:
- To elucidate the specific mechanisms by which translational control is deregulated in cancer.
- To characterize the innate specificity of the translational apparatus in gene expression modulation.
- To identify novel therapeutic targets by understanding the role of translational control in cancer.
Main Methods:
- Analysis of translational reprogramming in cancer cells.
- Investigation of mRNA network modulation during oncogenesis.
- Study of ribosomopathies and their link to cancer susceptibility.
Main Results:
- Deregulated translation significantly impacts cancer initiation and progression.
- Specific mRNA networks, rather than global protein synthesis, are key targets of oncogenic pathway activation.
- Mutations in ribosome components (ribosomopathies) are linked to specific pathologies and increased cancer risk.
Conclusions:
- Translational control exhibits striking specificity that is crucial for normal cellular function and is altered in cancer.
- Characterizing this specificity provides fundamental insights into cancer biology.
- Targeting specific translational mechanisms presents a promising avenue for novel cancer therapies.

Leaky Scanning
During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA. Marilyn Kozak discovered that the sequence RCCAUGG (where R stands for...
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.

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...
