digestive/alimentary system
decreased colon length ( J:300275 )
• in mice treated with tamoxifen and DSS
• however, treatment with TNF attenuates exacerbated DSS-induced colon reduction
increased susceptibility to induced colitis ( J:300275 )
• in mice treated with tamoxifen and DSS with increased body weight loss, disease activity scores, and enteroscopic and histological colitis scores, and reduced colon length that are not responsive to LPA treatment
• increased inflammation is not associated with higher macrophage infiltration into the colonic lamina prioria in mice treated with tamoxifen and DSS
• however, treatment with TNF attenuates exacerbated DSS-induced colitis

growth/size/body
increased susceptibility to weight loss ( J:300275 )
• in mice treated with tamoxifen and DSS
• however, treatment with TNF attenuates exacerbated DSS-induced weight loss

immune system
increased susceptibility to induced colitis ( J:300275 )
• in mice treated with tamoxifen and DSS with increased body weight loss, disease activity scores, and enteroscopic and histological colitis scores, and reduced colon length that are not responsive to LPA treatment
• increased inflammation is not associated with higher macrophage infiltration into the colonic lamina prioria in mice treated with tamoxifen and DSS
• however, treatment with TNF attenuates exacerbated DSS-induced colitis

homeostasis/metabolism
abnormal corticosterone level ( J:300275 )
• lower corticosterone concentrations from the supernatants of colonic explants of mice treated with tamoxifen and DSS
• however, treatment with TNF increases corticosterone concentrations from the supernatants of colonic explants of mice treated with tamoxifen and DSS
