IQGAP2 and colitis: Consistent with the results in the acute colitis model described above, Iqgap2-/- mice showed no signs of colitis after a 7-day recovery period, while WT mice showed only a partial recovery, with body weights at 95% of the basal levels and small unrepaired areas of colonic epithelium still present (Fig 2C, right panel and S5 Fig).
