neoplasm
• found in about 65% of one year old mice, averaging about 1.5 tumors per mouse
• tumors appear first in the small intestine, then the large intestine, never in the stomach
• epithelial in origin, becoming invasive carcinomas in older mice
|
cardiovascular system
• fecal blood found as early as 6 months of age when gastrointestinal tumors can also be found
|
digestive/alimentary system
• fecal blood found as early as 6 months of age when gastrointestinal tumors can also be found
|
• mice exhibit distorted and flattened structure of the epithelial cells
|
• los of the mucus layer of the distal colon
• loss of lamina propria architecture
• the lamina propria shows an increase in total cells, CD4+ and CD8+ T lymphocytes and IgA-producing B cells
|
• absent in the intestine
|
• increase in crypt length, particularly in the distal colon
|
• found in about 65% of one year old mice, averaging about 1.5 tumors per mouse
• tumors appear first in the small intestine, then the large intestine, never in the stomach
• epithelial in origin, becoming invasive carcinomas in older mice
|
• mice exhibit bacteria on the epithelium and in crypts of the distal colon indicating compromised mucus barrier
|
• intestinal epithelial cells exhibit decreased apoptosis
|
• intestinal epithelial cells exhibit increased proliferation
|
• mice exhibit cell infiltration and superficial epithelial erosions that are more pronounced at the distal end of the colon
• the colon lamina propria shows an increase in total cells, CD4+ and CD8+ T lymphocytes and IgA-producing B cells
• only a subset of mutants show signs of inflammation in the colon characterized by neutrophil infiltration in the colon lamina propria corresponds with decreased number of CD103+CD11b- dendritic cells and increased number of CD103+CD11b+ dendritic cells and CD103-CD11b+ macrophages in the colon
|
• mice develop spontaneous colitis between 8 and 20 weeks of age
• mice exhibit a higher bacterial burden than controls in the colon and mesenteric lymph nodes due to compromised mucus barrier in the intestine
|
endocrine/exocrine glands
• increase in crypt length, particularly in the distal colon
|
immune system
• mice exhibit cell infiltration and superficial epithelial erosions that are more pronounced at the distal end of the colon
• the colon lamina propria shows an increase in total cells, CD4+ and CD8+ T lymphocytes and IgA-producing B cells
• only a subset of mutants show signs of inflammation in the colon characterized by neutrophil infiltration in the colon lamina propria corresponds with decreased number of CD103+CD11b- dendritic cells and increased number of CD103+CD11b+ dendritic cells and CD103-CD11b+ macrophages in the colon

|
cellular
• absent in the intestine
|
• intestinal epithelial cells exhibit decreased apoptosis
|
• epithelial cells in the intestinal mucosa migrate more rapidly
|
• intestinal epithelial cells exhibit increased proliferation
|
• in intestinal epithelial cells
