Visualization of modifications in the human ribosome europs, a re feat for cryo electron microscopy Ribosomes play a vital role in living beings: These large complexes are made up of two kinds rencnotre molecules: Published in the journal Nature Stie November 15these results not europw provide a better understanding of the structural and functional roles of human ribosome modifications, but also Site de rencontre gratuit en europe up new therapeutic pathways for the treatment of pathologies such as cancer or certain genetic diseases in which dysregulation of protein synthesis is involved.
Genuine molecular machines, ribosomes decipher the information contained in a copy of DNA, called messenger RNA, to synthesize proteins. During ribosomes biogenesis, chemical modifications occur at precise locations of rRNAs. The alteration of these modifications is sometimes associated with disruptions in protein synthesis. Moreover, these modifications in the rRNA structure seem to modulate the activity of antibiotics, indicating that they can influence the ribosome interaction with this kind of drugs.
Chemical modifications of rRNA have been known for decades, particularly in microbes, but their observation remained difficult. In this study, Bruno Klaholz's team at the IGBMC determined the localization and three-dimensional structure of various types of modifications methylations, acetylations, etc. The researchers have thus uncovered the role of these chemical modifications which consists in stabilizing the rRNA structure.
The researchers also analyzed the structure of three antibiotics-binding sites, revealing that these molecules are either in direct contact or very close to the rRNAs modifications sites, implying a role of these modifications in the mechanism of action and specificity of these inhibitors. Moreover, the unexpected presence of certain rRNA modifications suggests that rRNA modifications in human ribosomes could vary between different cell types, especially between normal cells and cancer cells, and could thus constitute a signature for cancer states.
This study represents a major result made possible by cryo electron microscopy, a revolutionary method for the observation of macromolecules coupled with image processing and 3D reconstruction, by which the researchers were able to construct a detailed atomic model of the human ribosome. Recognized recently by the Nobel Prize in Chemistrythis technique provides the double advantage of being able to study biological samples without altering their properties and also allows to fix the orientation of the objects to enable a 3D reconstruction.
Beyond mapping at the atomic level, the visualization of rRNA chemical modifications provides unprecedented insights into their role in the stabilization of rRNA structure, in the translation process and in diseases related to ribosome dysfunctions, paving the way for the development of new drug. Electron cryo-microscopy is honored! This technique allows not only to study biological samples without altering their properties, as it is the case with dyes, but also to produce high-resolution three-dimensional structures of biomolecules which represents a revolution in the field of structural biology.
