PG - 177-82 LID - 10.1016/j.fsi.2008.09.009 [doi] AB - Two forms of progranulin mRNA were isolated from kidney and spleen cDNA libraries of the olive flounder, Paralichthys olivaceus. The 3'-untranslated regions (3'-UTRs) of these flounder progranulin (f-pgrn) mRNAs differed in a 20-nucleotide sequence element (5'-AACTGATTACGTTCAACAAC-3') that was present in one mRNA (designated f-pgrn type II) and not in the other (designated f-pgrn type I). Both mRNA sequences contained an open reading frame encoding a 289-amino-acid polypeptide of approximately 33 kDa. Southern blot analysis of the P. olivaceus flounder genome using an f-pgrn cDNA probe and a PCR-based approach identified a single copy of f-pgrn corresponding to the type II mRNA. The expression profiles of the two types of f-pgrn mRNA differed from each other and were tissue- and condition-dependent. The type II mRNA was detected abundantly in studied tissues (gill, kidney, spleen, and intestine) of non-stimulated healthy flounders. The type I mRNA was rarely expressed in any tissues of healthy flounders, but it was continuously increased in the examined tissues of flounders after the intraperitoneal injection of lipopolysaccharide. On the other hand, the expression of type II mRNA was decreased in inverse proportion to the type I mRNA in the LSP-stimulated flounders. These results suggest that type I and type II f-pgrn mRNA are translated into different proteins with different activities in the immune system of flounder.
