Fold changes in NHE3 and PTGS2 mRNA expression in polarized Caco-2 cell monolayers after 24-h exposure to IL-1α

		Concentration of Recombinant Human IL-1α
Gene Name	Control	10 ng/ml	100 ng/ml	500 ng/ml
NHE3	1.07 ± 0.18^a	1.48 ± 0.32^a	1.60 ± 0.49^a	1.28 ± 0.29^a
PTGS2	1.00 ± 0.05^a	2.00 ± 0.24^b	2.38 ± 0.34^b	2.02 ± 0.20^b

Data are means ± SE of fold differences in gene expression measured by quantitative RT-PCR; n = 6. NHE3, Na⁺/H⁺ exchanger; PTGS2, prostaglandin-endoperoxide synthase 2. Significantly different values are marked in bold.

^{^a,b}

Each gene marked with a different superscript differs by at least P < 0.05 compared with control.
