Figure 2. Cellular amphiregulin levels in human epithelial colorectal adenocarcinoma Caco-2 cells incubated with iron compounds.

Quantative data measured with Thermo Scientific™ hAREG ELISA kit. Data are presented as means, n=3 ± SD. The significance of the differences is expressed as letters a-e where a: p=2,5E⁻⁷, b: p=2,4E⁻⁵, c: p=1,14E⁻¹⁰, d: p=9.9E⁻⁷, e: p=0.6. Differences of p <0.05 were considered as significant.
