mortality/aging
• following removal of DSS treatment, mice exhibit increased mortality compared to similarly treated wild-type mice
|
• 10% to 15% of mice develop intestinal problems and die prior to day 25
|
• mice with abdominal irregularities die prior to day 25
|
digestive/alimentary system
• at 2 to 3 days after birth, 10% to 15% of mice exhibit diarrhea and abdominal discoloration unlike wild-type mice
|
• cell proliferation and apoptosis of the epithelial layer in the colon is increased compared to in wild-type mice
|
• 10% to 15% of mice exhibit a thin-walled, pale small intestine
|
• severely affected animals display a nearly complete loss of crypt-villus structure in the ileum
|
• severely affected animals display a nearly complete loss of crypt-villus structure in the ileum
|
• despite removal of DSS mice continue to exhibit increased intestinal epithelial apoptosis and fail to recover unlike wild-type mice
|
• mice are more susceptible to colitis induced by long term DSS treatment than wild-type mice
• unlike wild-type mice, after 5 to 7 days of treatment with DSS mice exhibit rectal bleeding, more severe weight loss, increased mucosal damage, colon epithelial cell proliferation and apoptosis, increased PGE2, IL-6 and MCP-1 levels, and increased immune response
• following removal of DSS treatment, mice exhibit increased mortality compared to similarly treated wild-type mice
• despite removal of DSS mice continue to exhibit increased intestinal epithelial apoptosis
|
growth/size/body
• mice with abdominal irregularities exhibit decreased postnatal weight gain compared to wild-type mice
|
immune system
• mice are more susceptible to colitis induced by long term DSS treatment than wild-type mice
• unlike wild-type mice, after 5 to 7 days of treatment with DSS mice exhibit rectal bleeding, more severe weight loss, increased mucosal damage, colon epithelial cell proliferation and apoptosis, increased PGE2, IL-6 and MCP-1 levels, and increased immune response
• following removal of DSS treatment, mice exhibit increased mortality compared to similarly treated wild-type mice
• despite removal of DSS mice continue to exhibit increased intestinal epithelial apoptosis
|
endocrine/exocrine glands
• severely affected animals display a nearly complete loss of crypt-villus structure in the ileum
|
homeostasis/metabolism
• following removal of DSS treatment, mice exhibit increased mortality compared to similarly treated wild-type mice
