  • effect of qufeng tongluo recipe on expression of desmin and cd2ap proteins in adriamycin induced Nephropathy rats an experimental research
    Chinese journal of integrated traditional and Western medicine, 2014
    Co-Authors: Zhu Wang, Ruiping Li, Ye Wang

    Abstract:

    OBJECTIVE: To investigate the effect of Qufeng Tongluo Recipe (QTR) on the expression of desmin and CD2-associated protein (CD2AP) in Adriamycin-Induced Nephropathy rats. METHODS: The Adriamycin-Induced Nephropathy rat model was induced by a disposable intravenous injection of adriamycin. The model was successfully established after 3 weeks. Rats were then randomly divided into the blank control group (Group A, n =12), the model control group (Group B, n = 8), the small, medium, large dose QTR group (Group C, n = 8; Group D, n = 8; Group E, n = 8), and the positive control group (Group F, n = 8). From the fourth week normal saline was given to rats in Group A and Group B, QTR 1.0 g/mL, 2.1 g/mL, and 4.2 g/mL was respectively administered to those in Group C, D, and E. Prednisone 25 mg/kg was given to rats in Group F. All medication was performed by gastrogavage at 10 mL/kg, once daily, for 28 successive days. 24-h urinary protein excretion and sera biochemical indices were determined during medication. At the end of the experiment, ultrastructure was observed, mRNA expression of desmin, mRNA and protein of CD2AP were detected by Real-time PCR and Western blot. RESULTS: (1) Compared with Group B, 24-h urinary protein excretion significantly decreased in Group C, D, E, and F (P < 0.05). (2) Compared with Group B, Alb in Group C, D, and E increased (P < 0.05) and TC significantly decreased (P < 0.05). TG significantly increased in Group F (P < 0.05). (3) Results of electron microscope showed, compared with Group B, the morphology of foot cells was improved to various degrees in Groups D, E, and F, especially the foot process structure and the number of foot processes were significantly improved, which was more obviously shown in Group D and Group E. (4) mRNA expression of desmin, mRNA and protein of CD2AP increased in Adriamycin-Induced Nephropathy rats (P < 0.05). After intervention, when compared with Group B, mRNA expression of desmin and CD2AP were significantly lower in Group C, D, E, and F (P < 0.05). (5) Compared with Group A, expression of desmin and CD2AP significantly increased (P < 0.05). Compared with Group B, the expression of desmin protein were obviously lower in Group C, D, E, and F, and the protein expression of desmin obviously decreased in Group D, E, and F (P < 0.05). The protein expression of desmin and CD2AP gradually decreased in Group C, D, and E (P < 0.05). Compared with Group F, the expression of CD2AP protein obviously increased in Group C and D (P < 0.05); the expression of CD2AP protein obviously decreased in Group E (P < 0.05); the expression of desmin protein was higher in Group C, D, and E (P < 0.05). CONCLUSION: QTR's therapeutic effect on Adriamycin-Induced Nephropathy rats might be achieved through altered expression of desmin and CD2AP.

    Nan fang yi ke da xue xue bao = Journal of Southern Medical University, 2011
    Co-Authors: Wan-sen Sun, Yan-yun Ren, Zhu Wang

    Abstract:

    OBJECTIVE To assess the therapeutic effect of Qufengtongluo (QFTL) recipe against proteinuria and glomerular filtration membrane damage in rats with Adriamycin-Induced Nephropathy (AN). METHODS Fifty-six SD rats were randomized into normal control (A) and AN model groups. In the AN model group, the rat AN models established by a single intravenous injection of adriamycin via the tail vein were subdivided into model (B), QFTL recipe (C), prednisone (D), and benazepril (E) groups 3 weeks after adriamycin injection. The 24-h urinary protein level was measured and the expression of anionic sites on the filtration membrane was evaluated using electron microscope with PEI staining. Nephrin expression on the glomerular filtration membrane was detected with indirect immunofluorescence assay. RESULTS Compared with group A, the model group showed significantly increased level of 24-h urinary protein (P

  • Vincristine alleviates Adriamycin-Induced Nephropathy through stabilizing actin cytoskeleton.
    Cell & Bioscience, 2017
    Co-Authors: Lei Yin, Ye Wang, Youying Mao, Hejie Song, Wei Zhou, Zhen Zhang

    Abstract:

    Antimicrotubule agent vincristine (VCR) has long been known as an alternative treatment for frequent relapse nephrotic syndrome and steroid-dependent nephrotic syndrome (SDNS). However, the mechanism is unknown. Here we found that VCR at a dosage much lower than that as an antimicrotubule agent can alleviate adriamycin (ADR)-induced proteinuria and podocyte foot process effacement. In cultured podocytes, VCR prevents ADR-induced actin fiber disorganization. In both in vitro and in vivo models, VCR suppresses ADR-induced overexpression of α3β1 integrin and focal adhesion kinase (FAK). These data suggest that VCR may relieve ADR-induced Nephropathy through inhibiting injury-induced activation of integrin outside-in signaling to prevent actin cytoskeleton remodeling. Hence, our work reveals a novel role of VCR in regulating actin fiber assembly and provides first evidence on the therapeutic mechanism of VCR on nephrotic syndrome.

    Abstract:

    OBJECTIVE: To observe the effects of Qufengtongluo Recipe (QFTLR) on the expression of podocin mRNA and podocyte morphology in rats with Adriamycin-Induced Nephropathy (AN), and explore the possible mechanism mediating the therapeutic effect of QFTLR on nephropathic proteinuria. METHODS: SD rats were randomized into normal control group, AN model group (established by a single injection of adriamycin via the tail vein), and 3 intervention groups with QFTLR, prednisone, or benazepril treatment. After the corresponding treatments, the expression of podocin mRNA in the renal tissues was detected by RT-PCR methods, and the morphological changes of the podocytes were examined by electron microscope. RESULTS: Compared with the normal control group, the AN model group showed significantly lowered expressions of podocin mRNA (P

  • Effects of qufengtongluo recipe on expressions of HSPG mRNA and protein in Adriamycin-Induced Nephropathy rats
    Sichuan da xue xue bao. Yi xue ban = Journal of Sichuan University. Medical science edition, 2010
    Co-Authors: Wan-sen Sun, Yan-yun Ren, Yan-long Zhao

    Abstract:

    OBJECTIVE To investigate the expression of HSPG in glomerular base membrane of Adriamycin-Induced Nephropathy (AN) rats, and the effect of Qufengtongluo recipe on HSPG mRNA expression and proteinuria in AN rats. METHODS One hundred forty rats were used in this study, including 32 rats in normal control group. AN was induced in the left rats by a single tail intravenous injection of adriamycin. Three weeks later, 90 AN rats were randomly divided into five groups; the Nephropathy group (B, n=18), the Qufeng group (C, n=18), Qufeng and prednisone group (D, n=18), prednisone group(E,n=18) and benazepri group (F, n= 18). The rats in these five groups were treated with different combination of Qufeng recipe and prednisone. In each group, renal tissue samples were collected at week 3 and 7. The distribution, expression of HSPG was examined by indirect immunofluorescence, and semi-quantity RT-PCR, respectively. RESULTS (1) In AN rats, the diffuse fusion and effacement of foot processes were observed when model established. (2) Compared with Nephropathy group, the average fluorescence intensity of HSPG dramatically increased in Qufeng group and prednisone group (P < 0.01), similarly, it also increased in D and F groups (P < 0.01). (3) Compared with Nephropathy group, the expression of HSPG mRNA was significantly up-regulated in other groups. (P < 0.01), especially in C and F groups. There was significant negative correlation between the expression of HSPG and quantity of 24-hour proteinuria. CONCLUSION The abnormal expression of HSPG and their altered distributions may be an important molecular mechanism that leads to the occurrence and development of proteinuria in AN rats. The effect of Qufengtongluo recipe on nephrotic syndrome might be related to the alteration of HSPG expression and distribution in glomerulus.
