MYC and Hyperammonemia: Consistent with the data in Huh7 cells treated with low concentrations of NH4Cl, livers of spf‐ash mice, a model of constitutive hyperammonemia, displayed increased expression of c‐Myc and active dephosphorylated form of β‐catenin compared to WT control mice, suggesting how also in vivo this axis could be involved in the modulation of autophagy by ammonia.
