ART BIO MATTERS Conference - September 22-24, 2021

ART BIO MATTERSART BIO MATTERS (ABM) aims to provide a stimulating forum in which to explore current and new directions in the study of biological materials found in cultural heritage collections through a biannual meeting and a dedicated website. A key aspect of the forum is the opportunity to discuss research at any stage of completion among a balanced community of experts in a format designed to promote collegial dialogue and debate.

While the core disciplines of ABM are science, curatorial/cultural history, and conservation, ABM welcomes other stakeholders involved in cultural heritage studies.

New postdoctoral researcher – DR Florent Grélard

Florent Grélard
         Dr Florent Grélard

Since September, 2021, a new postdoctoral researcher, Florent Grélard, has joined the S2MB (Mass Spectrometry of Biological Macromolecules) team of the UMR CNRS 5248 Institute of Chemistry & Biology of Membranes & Nano-objects.
Florent has obtained his PhD in Computer Science, more specifically in image analysis, at the Laboratoire Bordelais de Recherche en Informatique (LaBRI), in Bordeaux. His PhD was about the characterization of tubular organs, such as airway trees or blood vessels. The characterization was achieved through precise measurements, using alternative representations of the object, such as orthogonal planes and skeletons. 
Florent has pursued his research in two postdoctoral positions: the first one in Lyon was about urban photographs indexing, and the second, in Nantes, was about the joint statistical analysis of mass spectrometry imaging and MRI.
In September 2021, Florent joined the CBMN in order to develop methods suited to the processing and analysis of images. In his project, he combines several imaging modalities, such as mass spectrometry imaging, immunofluorescence and Raman spectroscopy, to study tuberculosis.

Bordeaux Summer School 2021 - Advanced mass spectrometry applied to cultural heritage - June 16th-18th, 2021


Bordeaux Summer School - Advanced mass spectrometry applied to cultural heritage

June 16th - June 18th, 2021

This online summer school is an innovative and inter / multi-disciplinary training based on advanced mass spectrometry to decipher the complexity of cultural heritage material, i.e. artworks, archaeological and palaeological materials, via their organic macromolecular signatures uncoding (proteins, lipids, polysaccharides).

Lasting three days, the course is delivered remotely and combines lectures and workshops in sample preparation, current mainstream mass spectrometry techniques and their most recent improvements, omics, and bioinformatics, all within the framework of cultural heritage. The program is open to doctoral students, post-doctoral researchers, academics, as well as private and museum actors in analytical and heritage sciences.

Title : "New developments in high-resolution mass spectrometry for proteomic analysis applied to cultural heritage: study of intact proteins, their cross-linkages and interactions in artworks and museum objects".

Summary : Proteins in cultural heritage objects constitute a critical source of information. Their detection and characterisation can provide an accurate comprehension of the artist’s technique and formulations. A more in-depth insight of the state of conservation and history of the artwork can also be achieved through investigation at the molecular level of the degradation mechanisms induced by natural ageing, environmental factors or either by inappropriate conservation/restoration treatments. Firstly, the PhD was dedicated to the development of proteomic bottom-up and top-down strategies using mass spectrometry for the study of proteins at trace levels from historical and artistic objects. The potentialities of a combination of these two complementary approaches were highlighted in the study of Gainsborough’s drawings, where the presence of milk-based fixatives was revealed with samples collected with minimally invasive techniques. Information achieved with the peptidic analysis, such as the specific breed origin of the detected proteins and their modifications, were enriched through top-down analysis with the detection of highly modified proteoforms characterised by multiple cleavage patterns. Secondly, the PhD study aimed to achieve a better insight into the proteins’ structural and conformational alterations in an artwork. A strategy based on the elaboration of data from the bottom-up analysis was optimised to investigate the protein networks formations through the localisation and characterisation of cross-linked peptidic pairs. The methodology was initially tested on mock-ups of paintings (formulated with lysozyme mixed with lead white pigment) which were treated with oxidising agents and naturally aged. The detection of different reticulated products led to defining various molecular patterns characteristic of oxidative-based cross-links in the lysozyme protein which subsequently were detected in more complex samples from historical tempera paintings. The cross-linking examination, combined with an unbiased modification search, also was effective for a more exhaustive understanding of the conservation history of a Coptic manuscript subjected to ancient invasive restoration treatment. The detection of a great extent of lysine methylations and especially the characteristic fragmentation markers of formaldehyde-based cross-links provided the first analytical evidence of a potential parchment consolidation treatment based on gelatin-formol used by the Vatican library during restoration. The developed approach also offered a more accurate protein identification detecting peptides that passed unnoticed in the classical strategy because they were chemically modified or structurally unreachable. Finally, the action of some of the most common inorganic pigments on proteins molecular and structural changes was also investigated. Particularly, the role of these inorganic compounds in proteins conformational changes was investigated for the first time through Hydrogen/Deuterium exchange (HDX) studies via mass spectrometry (intact protein approach). The decrease of deuterium exchange observed for certain mixtures suggested the interposition of the pigment in the protein solvent accessibility, or/and the modification of the molecular conformation.

Title : "Extraction and analysis by liquid chromatography coupled with mass spectrometry of Lawsonia inermis and the study of its anti-melanoma effect".

Summary : Lawsonia inermis L. commonly called Henna belongs to the family Lythraceae. It is known for its traditional importance both as a cosmetic and medicinal agent, especially in the indigenous regions of North Africa, South Asia and Middle East countries. The different parts of this shrub; leaves, stems, seeds and roots have different chemical constituents such as naphthoquinones, polyphenols, flavonoids, tannins, etc, which have various biological activities. The interest of this Mediterranean plant, in addition to its cosmetic use, is its biological activity antimicrobial, anti-inflammatory, anticancer and many others. This research work has been particularly interested in studying its anticancerous effect and more particularly its potential anti-melanoma metastasis given its traditional use often as a topical treatment for irritated skin. This research work allowed, first of all, the development of an experimental plan for the optimization of the global yield of extraction of active molecules from Henna (Lawsonia inermis L.). In the second stage, the identification and quantification of active compounds by high performance liquid chromatography coupled with mass spectrometry.  A geographical mapping of henna crops in southern Morocco, using principal component analysis and based on the nature of the climate of each region was carried out. Subsequently, the effect of plumbagin on metastatic melanoma was studied. The study of this activity was evaluated in-vitro on murine and human cells respectively B16F10 and SKMEL-28. Plumbagin was found to significantly inhibit three important metastatic processes: migration, adhesion and invasion of B16F10 cells. These results were confirmed in the human cell line SK-MEL-28.
