Objective To investigate the general changes of up-regulated proteins in colonic mucosa from chronic slow transit constipation rats and analyze the function of the specified proteins. Methods An experimental rat model of chronic slow transit constipation (STC) was established by diphenoxylate and used for separating proteins from colonic mucosa by two-dimensional electrophoresis (2DE). ImageMaster 2DElite
mass spectrometry
protein bank and bibliometrics were applied to identify the up-regulated proteins and analyze their clinical significance and function. Results Obvious distinction was observed in the genesis of STC
such as calponin (CaP
A1),histone H2B (A2),rat aldoketo-reductase analog (A3). The expression of A1
A2
and A3 up-regulated in the gel graph of STC rats. Conclusion Calponin plays a vital role in regulating the gastrointestinal movement by amount alteration and mediates the effect of gastrointestinal dynamia of diphenoxylate.
