The role of TGF-β1 in mice hepatic fibrosis bySchistosomiasis Japonica

Summary To investigate the role of transforming growth factor-β₁ (TGF-β₁) in mice with hepatic fibrosis caused bySchistosomiasis Japonica, ELISA, VG staining and multimedia color hieroglyph quantitative analysis were used to study the change of the serum TGF-β₁, liver collagen fiber and reticular fiber in mice. The level of serum TGF-β₁ in experimental group was significantly higher than that in control group (P < 0. 01 orP < 0. 05) 8, 10, 12 weeks after infected by schistosomiasis. After infection, the level of liver collagen fiber and reticular fiber, and that of TGF -β₁ increased over time (P < 0. 01 orP < 0. 05). In mice infected bySchistosomiasis Japonica, the level of TGF-β₁ increased with prolongation of infection time, and with the increase of liver collagen fiber and reticular fiber. TGFβ₁ plays an important role of immunomodulation in hepatic fibrosis formation caused bySchistosomiasis Japonica.     

Effects of <Emphasis Type="Italic">Panax notoginoside</Emphasis> on the expression of TGF-β1 and Smad-7 in renal tissues of diabetic rats

In order to explore the effects of Panax notoginoside (PNS) on the expression of transforming growth factor β1 (TGF-β1) and Smad-7 in renal tissues of diabetes, a rat model of diabetic nephropathy was set up by intravenous injection of streptozotocin (STZ). Wistar rats were randomly divided into normal group, diabetic control group, group treated by PNS at low-dosage (PL), group treated by PNS at high-dosage (PH) and group treated by catopril (C), respectively. Fasting blood glucose (FBG), renal index, endogenous creatinine clearance rate (CCr) and urinary albumin (UAlb) in 24 h were examined after 6 weeks. Meanwhile, the expressions of TGF-β1 and Smad7 in renal tissues were immunohistochemically dectected. At the end of the sixth week, FBG, renal index, Ccr, UAlb were all elevated significantly in control group (P<0.01). The expression of TGF-β1 protein was increased while Smad7 protein decreased in renal tissue (P<0.01). However, the treatment with PNS reversed the aforementioned changes in renal tissues of diabetic rats. These results indicate that PNS possess a protective effect on the kidney of diabetic rats and it might protect kidney by inhibiting the expression of TGF-β1 protein and enhancing the expression of Smad7 protein.

Effect of Anluohuaxian Tablet Combined with γ-IFN on Schistosomal Liver Fibrosis

The therapeutic effects of anluohuaxian tablet combined with γ-IFN on schistosomal liver fibrosis and its mechanism were studied in a murine model and clinical cases of schistosomal liver fibrosis, Fifty Kunming mice were randomly divided into 5 groups： normal control group, infection control group, anluohuaxian tablet-treated group, γ-IFN-treated group and combined treatment （anluohuaian tablet＋γ-IFN） group. Pathologic changes in liver, including hepatic pigmentation and the size of schistosomal egg granuloma, were observed by HE staining after treatment for 8 weeks. The expression of the type Ⅰ and Ⅲ collagen, and TIMP-1 was detected by immunohistochemistry. TGF-β1 mRNA expression was examined by real-time fluorescent quantitative PCR. Sixty patients with schistosomal liver fibrosis were divided into treatment group and control group. The patients in treatment group were treated with anluohuaxian tablet in combination with γ-IFN for 6 months. Before and after treatment, the changes of symptoms and signs, liver function, serum liver fibrosis indexes and imaging indexes were observed. The results showed that as compared with infection control group, all forms of treatments relieved the hepatic pathological injury with apparently diminished size of schistosomal egg nodules and decreased percentage of pigmentation （P〈0.05）. Furthermore, the expression of collagen Ⅰ and Ⅲ, TIMP-1, and TGF-β1 mRNA in combined treatment group was significantly decreased as compared with anluohuaxian tablet-treated and γ-IFN-treated groups （P〈0.05）. In the clinical observation, the serum liver fibrosis indexes, the portal vein width as well as the spleen thickness was significantly reduced in treatment group as compared with control group （P〈0.05）. It was concluded that the combined use of anluohuaxian tablet with γ-IFN in schistosomal liver fibrosis could protect liver function, alleviate liver fibrosis, and could be used as a choice in treating patients with schiatosomal liver fibrosis.

Influence of High Level TGF-β1 on Scleral Thickness

In order to explore the role of TGF-β1 in scleral remodeling and the possible mechanism,the influence of high level TGF-β1 on scleral thickness and the expression of MMP-2 and TIMP-2 was investigated in a TGF-β1 transgenic mouse model.Alb/TGF-β1(Cys223,225Ser) TGF-β1 transgenic mice were used as experimental subjects and non-transgenic littermates as controls.Plasma levels of TGF-β1 were determined by ELISA.TGF-β1,MMP-2 and TIMP-2 levels in sclera were detected by using Western blot.The thickness of posterior sclera was measured by computerized image analysis of a midsagittal section.Mean difference was analyzed with independent t-test.The results showed plasma levels of TGF-β1 in transgenic mice were 1.68 times as much as that in the controls(P<0.01).TGF-β1 levels in the sclera of transgenic mice were 2.68 times of the controls(P<0.01).Posterior scleral thickness in transgenic mice were significantly thicker than in the controls.There was no significant difference in the MMP-2 levels between transgenic mice and controls,but the TIMP-2 levels were increased significantly in transsgenic mice as compared with those in the controls.It was suggested that high levels of TGF-β1 in transgenic mice could result in the increased scleral thickness by inducing the expression of TIMP-2 to suppress the activity of MMP-2,finally inhibiting the degradation of collagen.     

Effect of TGF-β1 on the expression of IL-12, IL-15, IL-18, IL-4 and IL-10 in heart transplantation rejection in rats

Summary To investigate the effect of TGF-β1 on the expressions of IL-12, IL-15, IL-18, IL-4 and IL-10 in heart transplantation rejection in rats, a model of rat cervical heterotopic heart transplantation was set up and the model rats were randomly divided into three groups: control group, transplant group and TGF-β1 group. The mRNA expression levels of IL-12, IL-15, IL-18, IL-4 and IL-10 were determined by RT-PCR at the 5th day after the transplantation. The mRNA expression levels of IL-12, IL-15, IL-18 were increased obviously and those of IL-4, IL-10 were significantly decreased in the transplant group as compared with the control group (P<0.01). In the TGF-β1 group, the mRNA expression levels of IL-12, IL-15, IL-18 were significantly decreased and those of IL-4, IL-10 were significantly increased as compared with the transplant group (P<0.01). The immunosuppressive effect of TGF-β1 on heart transplantation rejection was related to its inhibition of the expressions of Th1-type cytokines (IL-12, IL-15, IL-18 etc) and its promotion of the expressions of Th2-tpye cytokines (IL-4, IL-10).     

Protective effects of eplerenone on podocyte injury in adriamycin nephropathy rats

To investigate the protective effects of eplerenone on adriamycin-induced renal injury and the possible mechanisms involved,36 male Sprague-Dawley rats were randomly divided into control group,adriamycin nephropathy(AN) group and eplerenone-treated group(100 mg.kg-1.d-1 eplerenone).Blood pressure,24-h urinary protein,serum potassium,sodium and creatinine were measured 28 days after adriamycin injection(a single tail intravenous injection of 6.5 mg/kg adriamycin).The morphological changes of renal tissues were observed by light and electron microscopy.Immunohistochemistry and Western blotting were performed to examine the expression of TGF-β1 and desmin in renal cortex.The results showed that 28 days after adriamycin injection,there were no significant changes in the level of serum potassium,sodium,creatinine concentrations and blood pressure values in the rats of the three groups.Meanwhile,the 24-h proteinuria excretion in the AN group was significantly higher than that in the control group(P<0.01),but that in the eplerenone-treated group was substantially reduced when compared with that in the AN group(P<0.05).Mild mesangial cell proliferation and matrix expansion,diffuse deformation and confluence of foot processes in podocytes were found in the AN group.By contrast,rats in the eplerenone-treated group exhibited obvious attenuation of these morphological lesions.The protein expression of TGF-β1 and desmin in the AN group was markedly up-regulated in contrast to that in the control group(P<0.01),whereas that in the eplerenone-treated group was much lower than in the AN group(P<0.05).It was concluded that eplerenone may ameliorate the proteinuria and the development of pathological alteration in adriamycin-induced nephropathy presumably via the inhibition of cytokine release,and restore the morphology of podocytes independent of its blood pressure-lowing effects.
