Sheffield Kidney Institute, Northern General Hospital Trust, Sheffield, UK
Exp Nephrol 10:182-95. 2002..01), respectively. This data suggests that reduced MMP activity may contribute towards renal scarring, however this is not a result of reduced MMP transcription or activation, but likely to be due to the inhibition by TIMPs...

- Transglutaminase inhibition ameliorates experimental diabetic nephropathyLinghong Huang
Academic Nephrology Unit, Sheffield Kidney Institute, School of Medicine and Biomedical Sciences, University of Sheffield, Sheffield, UK
Kidney Int 76:383-94. 2009..Our study suggests that transglutaminase inhibition ameliorates the progression of experimental diabetic nephropathy and can be considered for clinical application...
- Effects of caspase inhibition on the progression of experimental glomerulonephritisBin Yang
Sheffield Kidney Institute, Department of Histopathology and Division of Clinical Sciences, Sheffield Teaching Hospitals, Sheffield University, United Kingdom
Kidney Int 63:2050-64. 2003..In a nephrotoxic nephritis (NTN) model, we previously demonstrated an up-regulation of caspase-3 that was associated with inappropriate renal apoptosis, inflammation, tubular atrophy, and renal scarring...
- A shift in the Bax/Bcl-2 balance may activate caspase-3 and modulate apoptosis in experimental glomerulonephritisBin Yang
Sheffield Kidney Institute, Division of Clinical Sciences, Department of Histopathology, Northern General Hospital Trust, Sheffield University, Herries Road, Sheffield, England S5 7AU, UK
Kidney Int 62:1301-13. 2002..However, its importance in controlling apoptosis in glomerulonephritis is unclear. Here, using the nephrotoxic nephritis (NTN) model, we evaluated Bax/Bcl-2 in relation to changes in the apoptosis co-ordination enzyme, caspase-3...
- An IGF-I antagonist does not inhibit renal fibrosis in the rat following subtotal nephrectomySimon D Oldroyd
School of Allied Health Sciences, De Montfort University, Leicester, UK
Am J Physiol Renal Physiol 290:F695-702. 2006..Thus an interventional study with an IGF-I receptor antagonist does not support a role for IGF-I in the development of renal fibrosis in the SNx rat, although IGF-I does make an important contribution to compensatory kidney growth...
