ABSTRACT
The compound 5-fluorouracil (5-FU) is used in cancer chemotherapy and is known to cause diarrhoea. We recently reported that chemokine (C-X-C motif) ligand 1 (CXCL1) and neutrophils in the colonic mucosa were markedly increased by the administration of 5-FU in mice. Curcumin has anti-inflammatory, antitumour and antioxidant properties. Therefore, we examined the effect of curcumin on 5-FU-induced diarrhoea development and CXCL1 and CXCL2 up-regulation in the colon. Mice were given 5-FU (50 mg/kg, i.p.) daily for 4 days. Curcumin (100 or 300 mg/kg, p.o.) was administered on the day before the first administration of 5-FU and administered 30 min. before the administration of 5-FU. Gene expression levels of CXCL1 and CXCL2 in the colon were examined by real-time RT-PCR. Curcumin reduced the 5-FU-induced diarrhoea development. Under this condition, the CXCL1 and CXCL2 gene up-regulated by 5-FU administration was inhibited by curcumin. The gene expression of CXCL1 and CXCL2 was also enhanced by 5-FU application in vitro. The 5-FU-induced up-regulated CXCL1 and CXCL2 gene expressions were inhibited by curcumin, Bay-117082 and bortezomib, nuclear factor kappa B (NF-κB) inhibitors, C646, a p300/cyclic adenosine monophosphate response element-binding protein-histone acetyltransferase (HAT) inhibitor. In conclusion, these findings suggested that curcumin prevented the development of diarrhoea by inhibiting NF-κB and HAT activation.
