Abstract
Background Hypoxia-reperfusion (HR) and inflammation are causes of renal allograft injury. Pathological evidence has indicated that ischemia followed by reperfusion leads to the proteolysis and destruction of the extracellular matrix (ECM) in renal tubular epithelial cells. Matrix metalloproteinases (MMPs), such as MMP-2 and MMP-9, play roles in cleaving and reshaping the ECM. Acute accumulation of MMP-9 secreted from neutrophils promotes the incidence of inflammation and exacerbates graft trauma. Our goal was to investigate the activities of MMP-9/MMP-2 and their correlation with HR injury and neutrophil-related inflammation in renal proximal tubular cells. Methods This model was established by placing HK-2 cells under hypoxic conditions (5% CO2, 1% O2) for 6 h and then exposing them to reperfusion (5% CO2, 21% O2) for 12 h in a tri-gas incubator. The cell culture medium was collected for culturing polymorphonuclear leukocytes (PMNs). BB-94 (MMP-9 inhibitor) was added to the culture medium in the inhibitor group. Results Flow cytometry showed a significant increase in reactive oxygen species (ROS) levels in HK-2 cells from the HR injury group. MMP-9 expression was significantly increased and MMP-2 expression was significantly decreased in HK-2 cells from the HR group. MMP-9 and MPO expression were significantly increased in the HR group, while MPO expression was significantly decreased in the PMN inhibitor group. Conclusions The outcomes indicated that MMP-9 and MMP-2 are important components of an underlying pathophysiological mechanism of injury following HR. MMP-9 inhibition may be a potential approach to mitigateHR injury.

Abstract
Matrix metalloproteinases (MMPs) are large family of proteinases. In addition to a fundamental role in the remodeling of the extracellular matrix, they also cleave a number of cell surface proteins and are involved in multiple cellular processes. MMP activity is regulated via numerous mechanisms, including inhibition by endogenous tissue inhibitors of metalloproteinases (TIMPs). Similar to MMPs, a role for TIMPs has been established in multiple cell signaling pathways. Aberrant expression of MMPs and TIMPS in renal pathophysiology has long been recognized, and with the generation of specific knockout mice, the mechanistic role of several MMPs and TIMPs is becoming more understood and has revealed both pathogenic and protective roles. This chapter will focus on the expression and localization of MMPs and TIMPs in the kidney, as well as summarizing the current information linking these proteins to acute kidney injury and chronic kidney disease. In addition, we will summarize studies suggesting that MMPs and TIMPs may be biomarkers of renal dysfunction and represent novel therapeutic targets to attenuate kidney disease.

Abstract
Chronic renal allograft injury is reflected by interstitial fibrosis and tubular atrophy (IF/TA) and by the accumulation of extracellular matrix (ECM). Metalloproteinases (MMPs) are renal physiologic regulators of ECM degradation. Changes in MMPs expression or activity may disturb ECM turnover leading to glomerular scarring and worsening renal function. Our goal was to investigate intragraft MMP2 and MMP9 activities and their correlation with renal dysfunction. Plasma MMP2 and MMP9 activities were analyzed as noninvasive markers of renal allograft deterioration. Transplanted patients were biopsied and histopathologically characterized as IF/TA+ or IF/TA-. Renal function was evaluated by serum creatinine, glomerular filtration rate (GFR) estimated by Modification of Diet in Renal Disease equation and urinary protein/creatinine ratio. Kidney and plasma MMP2 and MMP9 activities were analyzed by zymography. A significant renal dysfunction was observed in IF/TA+ patients. Intragraft proMMP9 showed a significant higher activity in IF/TA+ than in IF/TA- samples and was inversely correlated with the GFR. Intragraft proMMP2 activity tended to increase in IF/TA+ samples, although no statistic significance was reached. Circulating proMMP2 and proMMP9 activities did not show significant differences between groups. Our data provide evidence that correlates intragraft proMMP9 activity with the fibrotic changes and renal dysfunction observed in IF/TA.

Abstract
OBJECTIVE To assess the long-term impact (minimum of 3 years follow-up) of polymorphisms in cytokine genes in donor:recipient pairs on the results of the transplant. METHODS We compared genetic cytokine polymorphisms and the primary factors of risk for the development of chronic rejection in paired groups of renal transplant patients with and without chronic allograft nephropathy [CAN]. RESULTS Multivariate analysis indicated that the presence of the high-production TT genotype (codon 10) of the transforming growth factor beta-1 (TGFB1) was protective in receptors (p=0.017), contrasting with the increased risk when present in donor samples (p=0.049). On the other hand, in the case of the gamma interferon studied, the greater frequency of the high production allele was protective in the analysis of the donor group (p=0.013), increasing the risk of chronic nephropathy of the allograft when present in the recipients (p=0.036). CONCLUSION Our results highlight the importance of TGFB1 genotyping in donors, and indicate that polymorphisms in the gene of this cytokine in donor cells might contribute to the development of chronic allograft nephropathy.

Abstract
Studies have indicated that matrix metalloproteinase-2 (MMP-2) is vital for the patient's condition after renal transplantation. Although the allograft survival rate has been improved, the relationships between various clinical parameters in stable graft function and serum MMP-2 still need to be clarified. In this study, gelatin zymography and enzyme-linked immunosorbent assay were employed to measure MMP-2 level in the plasma of 152 kidney transplant recipients, 41 chronic kidney disease patients, and 50 healthy control subjects. The creatinine and the MMP-2 levels in the transplant recipients were significantly greater (P < 0.001) than those of control subjects. Univariate and stepwise regression analysis demonstrated the MMP-2 level was associated with cystatin C level (P < 0.001), creatinine level (P = 0.036), proteinuria (P = 0.043), posttransplant days (P = 0.025), and posttransplant diabetes mellitus (P = 0.03). We conclude that circulating MMP-2 is associated with cystatin C, posttransplant duration, and diabetes mellitus in kidney transplant recipients and suggest that MMP-2 may be critical for graft survival.

Abstract
Treatment of liver fibrosis and cirrhosis remains a challenging field. Hepatocyte injury and the activation of hepatic stellate cells are the 2 major events in the development of liver fibrosis and cirrhosis. It is known that several Chinese herbs have significant beneficial effects on the liver; therefore, the purpose of the present study was to investigate the therapeutic effect of saikosaponin-d (SSd) on liver fibrosis and cirrhosis. A rat model of liver fibrosis was established using the dimethylnitrosamine method. Liver tissue and serum were used to examine the effect of SSd on liver fibrosis. A hepatocyte culture was also used to investigate how SSd can protect hepatocytes from oxidative injury induced by carbon tetrachloride. The results showed that SSd significantly reduced collagen I deposition in the liver and alanine aminotransferase level in the serum. Moreover, SSd decreased the content of TGF-beta1 in the liver, which was significantly elevated after dimethylnitrosamine induced liver fibrosis. Furthermore, SSd was able to alleviate hepatocyte injury from oxidative stress. In conclusion, SSd could postpone the development of liver fibrosis by attenuating hepatocyte injury.

Abstract
Matrix metalloproteinases (MMPs) are a large family of proteinases that remodel extracellular matrix (ECM) components and cleave a number of cell surface proteins. MMP activity is regulated via a number of mechanisms, including inhibition by tissue inhibitors of metalloproteinases (TIMPs). Originally thought to cleave only ECM proteins, MMP substrates are now known to include signaling molecules (growth factor receptors) and cell adhesion molecules. Recent data suggest a role for MMPs in a number of renal pathophysiologies, both acute and chronic. This review will focus on the expression and localization of MMPs and TIMPs in the kidney, as well as summarizing the current information linking these proteins to acute kidney injury, glomerulosclerosis/tubulointerstitial fibrosis, chronic allograft nephropathy, diabetic nephropathy, polycystic kidney disease, and renal cell carcinoma.

Abstract
Recent data suggest that early changes in the process of acute renal transplant rejection (ARTR) occurring during the first 3 months after transplantation include interstitial fibrosis. Transforming growth factor beta (TGF-beta) has been recognized as a key mediator of renal fibrogenesis; therefore, the present study was conducted to ascertain immunoexpression of TGF-beta in ARTR. Another purpose of our study was to determine whether TGF-beta could correlate with the interstitial area and to examine a possible relationship between TGF-beta and interstitial alpha-smooth muscle actin (alpha-SMA), endothelin-1 (ET-1) expression, interstitial T lymphocytes, and monocytes/macrophages. Twenty-four renal allograft biopsy specimens obtained from patients with ARTR were examined using percutaneous renal biopsy. As a control, we used 11 allograft biopsy specimens obtained from patients without any sign of rejection. Staining intensities of TGF-beta-1 in tubuli and of ET-1 in the endothelium of peritubular capillaries, in arterioles, and in the renal tubular epithelial cells were recorded semiquantitatively, whereas interstitial CD3+ cells, CD68+ cells, alpha-SMA expression, and the interstitial area were assessed quantitatively using computer image analysis system. Our study revealed that in the ARTR group, the mean values of the immunoexpression of TGF-beta-1, ET-1, interstitial CD3+ cells, CD68+ cells, alpha-SMA expression, and the interstitial area were significantly increased as compared with controls. In the ARTR group, there were significant positive correlations between immunostaining of TGF-beta-1 and ET-1, immunostaining of TGF-beta-1 and alpha-SMA, as well as immunostaining of TGF-beta-1 and interstitial volume. The correlation between immunostaining of TGF-beta-1 and CD 3+ cells tended to be negative; however, this did not reach statistical significance. We did not find any significant relationship between TGF-beta-1 and interstitial monocytes/macrophages. In controls, all these correlations were not significant. In conclusion, our correlative study suggests a role of TGF-beta-1 in early interstitial fibrotic changes in acutely rejected renal allografts, and we hypothesize that endothelin-1 and myofibroblasts pathways may play an important role in this process.
