Figure 9. Mucin layer protects E-cadherin on intestinal epithelial cells from trypsin-mediated degradation.

Figure 9

Western blot for intra- and extra-cellular domains of E-cadherin of IEC-18 cells without a mucin layer after exposure with serum free without and with trypsin (SFM and SFM+Try respectively) and IEC-18 cell with a mucin layer after exposure to serum free media with or without trypsin (SFM+Mucin and SFM+Mucin +Try) (A) with corresponding density levels measurements (B). Values are mean±SEM (n = 4)/group, **P<0.001 and ***P<0.0001 compared to SFM; ††P<0.001, †††P<0.0001 compared to SFM+Mucin; and ‡‡P<0.001, ‡‡‡P<0.0001 compared to SFM+Mucin+Try.
