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.

The large ribosomal subunit has several important structures essential to translation. These include the peptidyl transferase center (PTC) - which is the site where the peptide bond is formed - and a large, internal, water-filled tube through which the nascent polypeptide moves. This latter structure is called the Peptide Exit Tunnel, and it begins at the PTC and spans the body of the large ribosomal subunit. During translation, as the nascent polypeptide chain is synthesized, it passes through...

Area of Science:

  • Neuroscience
  • Behavioral Science
  • Psychiatric Research

Background:

  • Significant unmet needs persist in treating major depression and neuropsychiatric disorders.
  • Traditional forward translation from animal models to human treatments has limitations.
  • A critical appraisal of preclinical-to-clinical translation is needed.

Purpose of the Study:

  • To review emerging reverse translation techniques in preclinical research.
  • To outline key considerations for implementing reverse translation.
  • To emphasize the role of reverse translation in advancing psychiatric treatments.

Main Methods:

  • Focus on reverse translation: developing animal assays based on human behavioral patterns.
  • Utilizing task performance to create behaviorally similar assays across species.
  • Integrating the Research Domain Criteria (RDoC) framework.

Main Results:

  • Reverse translation facilitates rigorous assessment of novel treatments in animal models.
  • This approach allows for testing invasive strategies prior to human trials.
  • Bidirectional research across species can accelerate drug discovery.

Conclusions:

  • Reverse translation offers a framework for innovative therapeutic strategies.
  • Key considerations include behavior, pharmacology, environmental factors, levels of analysis, and cross-species continuity.
  • This approach can advance treatment for resistant neuropsychiatric illnesses.
