digestive/alimentary system
• after tamoxifen (TAM) induction, most cells of the elongated colonic crypts are Ki67-positive, indicating colonic epithelial hyperplasia
• after TAM induction, colonic crypts exhibit significantly increased mRNA levels of markers for goblet cells (Muc2, Agr2) and secretory progenitors (Atoh1, Spdef and Neurog3), indicating increased mucin secretion
• however, mRNA levels of the stem cell marker Lgr5 are normal
• at 4 weeks after TAM induction, mice show significantly elongated crypts and compromised crypt integrity throughout the entire colon, with aberrant cell arrangements and irregular nuclei
• crypt elongation and loss of integrity is more evident in the proximal colon than in the mid to distal colon
• colonic crypts show a significant increase in Muc2 (mucin 2) expression
• after TAM induction, colonic crypts exhibit significantly increased mRNA levels of markers for goblet cells (Muc2, Agr2)
