| Study Title | The double-edged role of FASII regulator FabT in Streptococcus pyogenes infection - Metabolomics |
| Study Summary | In Streptococcus pyogenes, the type II fatty acid (FA) synthesis pathway FASII is feedback-controlled by the FabT repressor. A FabT mutation leads to bacterial growth defect in the presence of eukaryotic cells and their supernatant. We investigated a possible metabolic basis for the mFabT growth defect, which could reflect an incapacity to use cell-secreted products for growth. We used a metabolomics approach to assess metabolites that are differentially consumed by mFabT compared to the WT strain, cultivated in the presence of non-infected endometrial cells supernatants (HEC-1-A cells). HEC-1-A supernatants were inoculated or not with WT or mFabT strains during 8 or 16 h. The metabolite composition of these supernatants was analyzed by Proteigene (https://proteigene.com) using MxP® Quant 500 kit (Biocrates) by two analytical methods, LC-MS/MS for small molecules and FIA-MS/MS for lipids. This analysis was repeated on 3 independent series of supernatants. These analyses have a defined detection threshold (LOD) for each family of metabolite.

| Project Title: | The double-edged role of FASII regulator FabT in Streptococcus pyogenes infection |
| Project Type: | MS quantitative analysis |
| Project Summary: | In Streptococcus pyogenes, the type II fatty acid (FA) synthesis pathway FASII is feedback-controlled by the FabT repressor. A FabT mutation leads to FASII dysregulation, FAs membrane modification and bacterial growth defect in the presence of eukaryotic cells and their supernatant. We try to understand the consequences on bacteria metabolism. |
