Objective: To study the effect of Sijunzi Tang (SJZT)-containing serum on cell migration and proliferation
c-Myc mRNA and protein expression of injured intestinal epithelial (IEC-6) cell
so as to explore the mechanism of SJZT in promoting gastrointestinal mucosal injury repair. Method: Rats were selected to prepare SJZT-containing serum
and IEC-6 cell migration model was established by tips scratch method
so as to observe the effect of SJZT on cell migration. Real-time cell analyzer (RTCA) was used to determine the effect of SJZT-containing serum on IEC-6 cell proliferation
c-Myc mRNA and protein expressions were detected by Real-time PCR and Western blot analysis
respectively. Result: The 10% and 20% SJZT-containing serum stimulated IEC-6 cell migration 8 h after cell damage (P<0.01); 10% and 20% SJZT-containing serum increased IEC-6 cell proliferation 12 h after cell damage (P<0.01). 5%
10%
and 20% SJZT-containing serum enhanced IEC-6 proliferation both at 24
36 h after damage (P<0.05
P<0.01). Further studies showed that
10% and 20% SJZT-containing serum increased c-Myc mRNA and protein expressions that were closely correlated with gastrointestinal mucosal injury repair (P<0.01). Conclusion: Sijunzi Tang-containing serum can repair the injury of gastrointestinal mucosal barrier
the mechanism may be related to its effect in improving mucosal c-Myc mRNA and protein expressions and promoting IEC-6 cell migration and proliferation.
