Figure 3

Intestinal transit time of the BALB/c Kif26a-KO mice. Barium sulfate was administered orally and radiographs obtained after 4 and 8 h. Barium is observed in the large intestine of the WT (n = 4, 20-week-old female), and KO (n = 4, 20-week-old female) mice at 4 h. After 8 h, barium sulfate remains in the large intestine (arrows) of the KO mice but has been excreted from the large intestine in the WT mice. Areas in the upper left part of each radiograph are associated with barium sulfate that remained attached to the stomach lining.
