چکیده انگلیسی
Protocadherins, a subgroup of the cadherin superfamily of calcium-dependent cell adhesion molecules, are considered to play important roles in the developing embryo particularly in the central nervous system. The Protocadherin 8 (Pcdh8) gene comprises three coding exons in both human and mouse, and the exon junctions are precisely conserved between these two species. Alternative splicing of Pcdh8 RNA leads to the formation of two isoforms that differ in the length of the cytoplasmic domains. We have investigated the expression of these short and long variants of Pcdh8 during early mouse development by RT/PCR and in situ hybridization. We found that both isoforms were predominantly expressed in the nervous system, and that their expression patterns appeared to be developmentally regulated. However, the short variant had a broader pattern of expression than the long variant and was found in some non-neuronal tissues, such as paraxial mesoderm, developing somites, and in limb interdigital mesenchyme where massive programmed cell death occurs. The differential expression of two alternative cytoplasmic domain variants suggests that Pcdh8 may regulate cell adhesion in a variety of developmental processes, and that this may involve different intracellular interactions.
