TGFβ1 gene expression in the parietal peritoneum.
TGFβ1 mRNA was measured by RT-PCR. mRNA levels increased in Groups 2 and 4 compared to Group 1 but expression in Groups 2 and 5 was significantly lower than in Group 4. GAPDH expression served as a loading control. *p<0.05 vs. Group 1, #p<0.05 vs. Group 4.
