Gut microbiome metabolites alter genomic networks in PC12 cells relevant to autism spectrum diorders

Alterations in the composition of the gut microbiome have an emerging role in brain function and behaviour. We have porposed that short chain fatty acids (SCFA) including propionate and butyrate which are present in the diet and are fermantation products of many gastrointestinal bacteria are contributing environmental factors in autism spectrum disorders (ASD). Here we used the microarray technology to compare global changes in gene expression profiles following exposure of PC12 cells to structurally related SCFA propionate and butyrate each in two different concentrations. Large number of affected genes, common for both SCFA were identified, including genetic networks and GO processes implicated in ASD.
