          Abstract

          An extensive number of animal and clinical studies indicate that transforming growth factors-β (TGF-βs) play an important role in inflammatory and fibrotic diseases, including renal fibrosis. Recent mouse models harboring genetically engineered alterations in TGF-β pathways reveal complicated mechanisms of regulation of TGF-β activity in vivo. The purpose of this review is to present recent advances relevant to our understanding of the TGF-β-signaling system in renal physiology and pathophysiology.

          The effect of angiotensin-converting-enzyme inhibition on diabetic nephropathy. The Collaborative Study Group.

          Renal function declines progressively in patients who have diabetic nephropathy, and the decline may be slowed by antihypertensive drugs. The purpose of this study was to determine whether captopril has kidney-protecting properties independent of its effect on blood pressure in diabetic nephropathy. We performed a randomized, controlled trial comparing captopril with placebo in patients with insulin-dependent diabetes mellitus in whom urinary protein excretion was > or = 500 mg per day and the serum creatinine concentration was or = 1.5 mg per deciliter, creatinine clearance declined at a rate of 23 +/- 25 percent per year in the captopril group and at a rate of 37 +/- 25 percent per year in the placebo group (P = 0.01). Captopril treatment was associated with a 50 percent reduction in the risk of the combined end points of death, dialysis, and transplantation that was independent of the small disparity in blood pressure between the groups. Captopril protects against deterioration in renal function in insulin-dependent diabetic nephropathy and is significantly more effective than blood-pressure control alone.

              Targeted disruption of the mouse transforming growth factor-beta 1 gene results in multifocal inflammatory disease.

              Transforming growth factor-beta 1 (TGF-beta 1) is a multifunctional growth factor that has profound regulatory effects on many developmental and physiological processes. Disruption of the TGF-beta 1 gene by homologous recombination in murine embryonic stem cells enables mice to be generated that carry the disrupted allele. Animals homozygous for the mutated TGF-beta 1 allele show no gross developmental abnormalities, but about 20 days after birth they succumb to a wasting syndrome accompanied by a multifocal, mixed inflammatory cell response and tissue necrosis, leading to organ failure and death. TGF-beta 1-deficient mice may be valuable models for human immune and inflammatory disorders, including autoimmune diseases, transplant rejection and graft versus host reactions.
