All-trans-retinoic acid attenuates radiation-induced intestinal fibrosis in mice.
    The Journal of surgical research, 2008, Volume: 150, Issue:1

    Intestinal fibrosis leading to severe bowel dysmobility or obstruction is a troublesome adverse effect of abdominal or pelvic radiation therapy. We have recently reported that all-trans-retinoic acid (ATRA) prevents radiation- or bleomycin-induced lung fibrosis. Here, we examined the impact of ATRA on the mouse model of radiation-induced intestinal fibrosis.. We evaluated the histology of late radiation fibrosis in surgical samples. We then performed histological examinations and quantitative measurements of mRNA of interleukin-6 and transforming growth factor-beta(1) in intestinal tissues of irradiated mice with or without intraperitoneal administration of ATRA and investigated the effect of ATRA on the transdifferentiation and the production of collagen of irradiated human intestinal fibroblasts.. Human samples of late radiation enteritis showed thickened submucosa and serosa, consistent with mouse model. Administration of ATRA attenuated irradiation-induced intestinal fibrosis and reduced mRNA of interleukin-6 and transforming growth factor-beta(1). In vitro studies disclosed that ATRA suppressed the transdifferentiation of irradiated intestinal fibroblasts and diminished the production of collagen from the cells.. Our findings indicate that ATRA ameliorates irradiation-induced intestinal fibrosis. ATRA could be a novel approach in the treatment of fibrosis associated with chronic radiation enteritis.
