Mechanism of Action

In vitro	Treatment of hemin or AFC damped the expression of TFRC in CT26 cells, which can be significantly rescued by overexpression of OTUD1.
In vivo	Following the i.p. administration of Hemin (100 μM/kg), the HO-1 level in the renal cortex begins to increase gradually. The HO-1 level reaches its peak 24 h after this compound preconditioning. HO-1 is expressed mainly in the renal tubules. The HO-2 level in the kidney does not change following this chemical preconditioning.
