Objective: Acetaminophen (APAP) overdose causes acute liver injuries. Studies show that stem cell factor (SCF) and its receptor, c-Kit, enhance liver recovery from APAP-induced injuries in mice. In this study we explore the effect of SCF on activity of glutathione S-transferase (GSTs) enzymes which are considered to be important in APAP metabolism. Methods: We divided 45 Balb/c mice into three groups. Within each group there were three sub-groups of five mice per subgroup. The groups included: 1. APAP (300 mg/kg B.W., i.p.); 2. SCF (40 µg/kg B.W., i.p.) given.30 minutes after APAP (300 mg/kg B.W., i.p.), and 3.control mice treated with normal saline. The mice were sacrificed at 1, 12 and 24 hours, respectively. Hepatotoxicity was evaluated in the 24 hour group by histopathology and assessment of biochemical serum markers (ALT and AST). We assessed the levels of SCF receptor (c-Kit) protein and GST enzyme activities in the liver tissues.  Results: Hepatotoxicity was induced by APAP (300 mg/kg, B.W) as evident by both histopathological observations and a significant (p<0.05) increase in serum ALT and AST levels, which were reversed by SCF administered post-APAP. SCF administration after APAP administration significantly increased GSTs enzyme activity levels by 24 hours, however it led to a significant decrease in c-Kit protein level compared to the control and APAP groups. Conclusion: Our data suggest that SCF binding to its receptor (c-Kit) on liver cells may attenuate APAP-induced liver injuries by increasing GST activities in the livers of mice.
