Abstract |
Endothelin (ET)-1 is involved in the pathophysiology of various renal disorders, promoting renal cellular proliferation and extracellular matrix protein accumulation, and, thus, diminishing fundamental renal function, including filtration. To determine whether ET-1 and ET-2 play a role in feline chronic renal failure, we analyzed the messenger RNA ( mRNA) expression of the prepro-ET (PPET )-1 and PPET-2 genes in affected cat kidney after molecular cloning of full-length PPET-2 complementary DNA ( cDNA). Conceptual analysis of the primary structure of cat PPET-2 based on the cloned sequence demonstrated that the putative regions corresponding to a mature peptide and peptidase processing sites are present in cat PPET-2. Homology analysis showed that the similarity of the cat PPET-2 amino acid sequence with those from human, mouse, rat, rabbit, dog, ferret, cow, and horse was 73.0%, 68.6%, 69.1%, 76.4%, 81.2%, 83.1%, 76.3%, and 79.2%, respectively. Analysis of PPET-1 and PPET-2 mRNA in cat by reverse transcription polymerase chain reaction showed upregulated expression of both genes in kidneys affected by renal failure.
