Abstract [en]

Carcinoembryonic antigen (CEA) is a tumor marker of wide clinical use though its function remains unknown. The CEA counterpart and some related macromolecules cannot be demonstrated in mice, thus prohibiting studies of CEA function by gene disruption strategies. In an attempt to find a relevant animal model for functional studies of CEA we have investigated the occurrence of CEA subgroup members in baboon and African green monkey at the genomic and mRNA levels. The investigation was focused on the characteristic immunoglobulin-variable region-like (IgV-like) N-terminal domain of the family members. Based on N-domain sequences 3 and 4 different CEA subgroup genes, respectively, were identified. One sequence in each monkey species corresponded to human CEACAM8, while it was not possible to assign an obvious human counterpart for the other N-domain sequences. However, studies of cDNAs from African green monkey COS-1 cells identified one of the sequences as CEACAM1. Expression of CEACAM1 mRNA and protein was upregulated by IFNgamma as has previously been demonstrated for human CEACAM1. Presence of GPI-linked CEA subgroup members in African green monkey was suggested by sequencing. Both monkey species would thus seem suitable for functional studies of selected CEA subgroup members.
