- Evolution of desmosomal genes in teleost fish and expression analysis of desmosomal cadherins in the gilthead sea bream (Sparus aurata)Publication . Silva, Melina Coelho da; Power, DeborahFish aquaculture is a viable and profitable industry worldwide and monitoring fish larvae health and growth is a key step. The gilthead sea bream (Sparus aurata) is an economically important species reared mainly under mesocosm and intensive aquaculture systems. However, heterogeneous larvae growth and anatomic deformations are observed using these systems and few molecular markers to monitor fish growth are currently in use. Desmosomes are a type of cell-cell junction formed by a protein complex that promotes strong connections between cells, playing a crucial role in the maintenance of tissue integrity. Desmosomal genes are well studied in human but poorly in fish, thus their potential as an additional molecular marker to monitor fish growth and health in aquaculture remains to be explored. The aim of this project was to study the desmosomal genes evolution in fish and characterize their potential involvement in fish development and physiology in aquaculture. The results showed that desmosomal genes largely expanded in fish when compared to other vertebrates and teleosts possess a single desmocollin (dsc); three desmogleins (dsg a,b and c); two plakoglobins (pg a and b); two desmoplakins (dp a and b) and seven plakophilins (pkp 1a, 1b, 2, 3a, 3b, 4a and 4b). Dsc and dsg b were the candidates and their expression in Sparus aurata was analyzed in various experiments. In general their expression in larvae was not affected by the aquaculture systems. However, these genes seem to be associated with growth, in larvae exhibiting heterogeneous growth, the smaller individuals have the dsg b expression significantly up-regulated (p < 0.05) compared to the dsc. Thus these genes have potential to be used as molecular markers of growth. Different dsc profile expressions were found among the experiments, revealing that genetic background may also influence the expression of this gene.
