Representative downstream target proteins of the AKT/mTOR and MAPK signaling pathways (p-mTOR, p-4EBP1, Ras and PanERK) were also strongly activated, as expected, in NNM and PTx induced FAH, and also after OTx, but are not detectable after TTx. Here, MTOR is linked to Fanconi anemia complementation group A.
