(B) Log2 fold-change of GDF11 expression in excitatory and inhibitory neurons isolated from post mortem brains from individuals with Rett syndrome and Gdf11 expression in Mecp2-knockout (Mecp2-KO), mutant (Mecp2 MT), and MECP2 overexpression (MECP2 OE) mouse model RNA-seq experiments. This evidence concerns the gene GDF11 and Rett syndrome.
