Dimethylhydrazine (DMH) is a potent colonic and hepatic carcinogen that is metabolized into oxyradicals causing liver injury and DNA mutations.is a well-documented medicinal herb that possesses anti-inflammatory, antioxidant and antitumor activities and is commonly used to treat diverse ailments. The present study aimed to reveal the hepatoprotective effects ofaqueous extract during an intermediate stage of colorectal cancer (CRC) in mice. Male Balb/c mice were divided into six groups: group A served as control, group B received chamomile extract (150 mg/Kg b.w.) orally for 12 weeks, and groups C-F received weekly intraperitoneal injections of DMH (20 mg/Kg b.w.) once a week for 12 weeks. In addition to DMH, groups D and F received chamomile during the initiation and post-initiation stages, respectively. Blood and liver samples were collected for biochemical and molecular analyses. The results showed that DMH induced hepatic injury in mice as shown by significant increase in serum aspartate aminotransferase and alanine aminotransferase. The changes in biochemical parameters were accompanied by activation of the Wnt signaling pathway leading to increased hepatocytes proliferation as well as inflammation evidenced by high levels of pro-inflammatory enzymes cyclooxygenase 2 (COX-2) and inducible nitric oxide synthase (iNOS). The results also showed potential hepatoprotective effects of chamomile extract against DMH-induced liver injury, proliferation and inflammation. Chamomile restored the biochemical and molecular parameters and this improvement was more pronounced in mice pretreated with the extract. In conclusion, chamomile extract may exert its hepatoprotective activities against DMH probably due to the antioxidant, antiproliferative and anti-inflammatory properties of its flavonoids.
