Final Report Abstract

Rapid, diverse, and robust amplification is characteristic of EOMES-expressing tissue. EOMES is found during the formation of the embryonic head and cardiac mesoderm, but also in activated T cells, cancer, and inflamed tissue. The context of this EOMES-driven amplification is often ambivalent and elusive, and therefore the subject of controversy. We hypothesize that excitotoxicity leads to cell cycle promotion in a glycolytic context, where EOMES most effectively promotes fate-specific target genes. It is important to note that this hypothetical link between the occurrence of these EOMES+ systems through excitotoxicity has not yet been systematically investigated. In summary, we can already deduce critical markers on the “border” of physiological neurogenesis from our RT-PCR validated RNAseq analysis and morphological assays, whilst we want to complete the landscape by covering the translational level (mass spectrometry) and the epigenetic level (meATACseq) with the same aliquots from all experiments. By joining all these levels, an unbiased multi-omics analysis across the specific different cell populations analysed will provide the scientific community with a rich dataset that challenges old dogmata and opens new questions on corticogenesis. Moreover, by testing the influence of MIA during cortical development, we are uncovering the role of the environment in the expression of Tbr2 which shed light on the molecular events that support the formation of IPs.
