Ischemic effect on nitrogen metabolism due to limited oxygen availability. (A) Intracellular amino acid profile of individual cultures as fold accumulation compared to control conditions (B) sPLS-DA principal component analysis based on cellular amino acid profiles. (C) Simplified pathway of cellular ammonia detoxification showing transcript level-independent urea cycle activity in low flux conditions, resulting in increased nitrogen efflux via urea and nitric oxide.
