PRE-084 ameliorates adenine-induced renal fibrosis in rats.

| Abstract |
2-(4-morpholinoethyl)- 1-phenylcyclohexane-1-carboxylate hydrochloride (PRE-084) is a selective sigma 1 receptor agonist. It has been shown that PRE-084 protected various tissues from experimental injury. However, no reports are available on its effect on renal fibrosis. Rat model of adenine-induced chronic kidney disease was chosen to study this. Adenine feeding in rats caused renal dysfunction as shown by increased serum creatinine and reduced creatinine clearance along with increased high molecular weight (HMW) urine protein excretion. Further, adenine feeding induced profibrotic changes in the kidney as reflected by increased expression of alpha-smooth muscle actin (α-SMA), fibroblast specific protein-1 (FSP-1) and matrix metalloproteinase-2 (MMP-2) activity; reduced cytokeratin expression. Further, there was excess deposition of extracellular matrix in the kidney, a striking character of fibrosis. However, administration of PRE-084 to adenine fed rats led to reduction in creatinine and proteinuria parameters partly. This was accompanied by reduced expression of α-SMA, FSP-1 and MMP-2 activity and slight restoration of cytokeratin levels leading to reduced extracellular matrix deposition in the kidney. These data demonstrate that PRE-084 partly ameliorated renal dysfunction and exhibited anti-fibrotic potential in the kidney of adenine fed rats.
