Research indicates that gut microbial metabolites, such as SCFAs and -tocopherol, can activate various G protein-coupled receptors (e.g., FFAR2, OLF78, GPBAR1) on the surface of EC cells, thereby promoting the expression of tryptophan hydroxylase 1 (TPH1) and the release of 5-HT (252255)

However, drastic redistributions of MDM2 from p53 to the IGF-1R can probably only be achieved after experimental modulations, like inhibition of p53 expression by antisense strategies, etc, and do not likely occur in this manner in a physiologic context
