Cell experiment: Regulatory effect of IGF-1 LR3 on intestinal epithelial cell barrier Intestinal epithelial cell lines, such as Caco-2 cells and IEC-6 cells, are often used to construct in vitro barrier models
However, Maiorino and co-workers recently redefined the catalytic motif of GPx1 as tetrad by establishing through mutagenesis study in Drosophila model that asparagine (Asn or N) residue was also essential for the catalytic activity of GPx1 [13]
