- Caffeic acid phenethyl ester prevented radiation-induced hepatic injury in rat.
- Caffeic acid phenethyl ester reversed the serum levels of alanine aminotransferase and aspartate aminotransferase and decreased the number of apoptosis cells in rat liver induced by radiation.
- Caffeic acid phenethyl ester may be a new hepato-protective compound against radiation-induced hepatotoxicity.
Caffeic acid phenyl ester (CAPE) is a potent anti-inflammatory agent and it can eliminate the free radicals. The current study was intended to evaluate the protective effect of CAPE against the acute radiation-induced liver damage in rats. Male Sprague-Dawley rats were intraperitoneally administered with CAPE (30 mg/kg) for 3 consecutive days before exposing them to a single dose of 30 Gy of β-ray irradiation to upper abdomen. We found that pretreatment with CAPE significantly decreased the serum levels of alanine aminotransferase and aspartate aminotransferase and increased the activity of superoxide dismutase and glutathione. Histological evaluation further confirmed the protection of CAPE against radiation-induced hepatotoxicity. TUNEL assay showed that CAPE pretreatment inhibited hepatocyte apoptosis. Moreover, CAPE inhibited the nuclear transport of NF-κB p65 subunit, decreased the level of tumor necrosis factor-α, nitric oxide and inducible nitric oxide synthase. Taken together, these results suggest that pretreatment with CAPE offers protection against radiation-induced hepatic injury.
