To carry out their activities, Research Teams of the Frédéric Joliot Institute for Life Sciences have developed high-profile technological platforms in many areas : biomedical imaging, structural biology, metabolomics, High-Throughput screening, level 3 microbiological safety laboratory...
All the news of the Institute of life sciences Frédéric Joliot
A team from I2BC@Saclay (SB2SM), in collaboration with the RPBS platform, has put online a server for structural prediction of interactions between proteins. This server, designed for biologists, uses the information provided by the coevolution of protein sequences and predicts the structure of protein complexes, essential information for understanding their functional role.
NeuroSpin researchers (UNATI and UNICOG), in collaboration with the Timone Neuroscience Institute, have studied a type of individual anatomical variation in the structure of the human cortex, the transverse gyrus or 'fold crossing', which separates grooves in two parts. They showed that the presence of this structure in the upper temporal groove is heritable. This result is important, given the role of this region of the brain in the production of language.
A SIMOPRO project supported by SATT Paris-Saclay: in vivo validation of the efficacy of the DTR8 molecule, developed and patented at SIMOPRO (Department of Medicines and Technologies for Health) in collaboration with Inserm, as a treatment for glomerulonephritis rapidly progressive.
Last April, a delegation of experts from the DRF visited colleagues at the Butantan Institute of São Paulo, a biomedical research center that has had close links with several researchers at the Joliot Institute since 2014. This mission is is concluded by the signing of a framework agreement between the two institutes in the field of therapeutic and vaccine innovation.
Two Research Teams from I2BC@Saclay and SPI (LI2D, Marcoule), in collaboration with IRAMIS, highlight the very strong affinity of silica nanoparticles for proteins with RGG motifs (family of binding proteins). RNA), especially when these are methylated. These results are important for the development of safe by design approaches.
The SHFJ LDM-PET team (GIP Cyceron, Caen), in collaboration with the University Hospital of Caen, successfully used, for the first time in the clinic, the radiopharmaceutical drug developed and produced by the researchers of the team. , the [18F] Fludarabine. This drug, which is innovative for lymphoproliferative diseases, has been shown to be more effective in terms of specificity and sensitivity than its current counterpart, [18F] FDG.
Collaborative work between the SBIGeM (I2BC@Saclay) and the Marseille Cancer Research Center, published in Molecular Cell, illuminates the mechanistic basis and genetic control of homologous recombination, a mechanism for repairing DNA breaks responsible for chromosome exchange during meiosis. However, canonical models do not explain the complexity of meiotic recombination profiles and this study, which reconstructs reaction intermediates, constitutes a major advance in the understanding of this mechanism.
In a study published in Analytical Chemistry, the Mass Spectrometry Research Team of the Laboratory Drug Metabolism Research Laboratory (SPI) demonstrated the interest of Orbitrap Fusion, a state-of-the-art mass spectrometer for the identification of relevant metabolites based on their masses and isotopes measured with high accuracy.
