The expression of TFF3 genes in cells effect by LPS and rhTFF3. Cells were treated with a final concentration of, respectively; 1, 10, 100 μg/mL of endotoxin and 50 μg/mL of rhTFF3, the amount of TFF3 gene expression respectively 0.11, 0.58, 1.48, and 0.71 times of the control group, shows that concentration of 100 μg/mL of endotoxin plays an enhanced role in TFF3 gene expression in cells. With the concentration of 1 μg/mL, 10 μg/mL of endotoxin and 50 μg/mL rhTFF3, TFF3 gene expression in cells with different degree of inhibition.
