Objective To explore the expression profile of Wnt4 in rat kidney during renal development and its effect on renal development. Methods Rats with embryonic age of 18 days (E 18 d) , 20 days (E 20 d) as well as postnatal age of 0 day (P 0 d), 1 day (P 1 d), 3 days (P 3 d), 5 days (P 5 d) and 7 days (P 7 d) were selected. Expression levels of Wnt4 in rat kidney during renal development were quantified by immunohistochemistry and Western blot in all time points. Results Immuno?histochemistry analysis showed that during E 18 d to P 7 d, Wnt4 mainly expressed in proximal tubules, ureteric bud, comma shaped bodies and S shaped bodies of nephrogenic zone;the expression in the distal tubule was weak;the expression in renal corpuscle decreased with time;Western blot analysis showed that the expression of Wnt4 in rat kidney began to decrease from E 18 d and reached bottom at P 1 d then rise again until P 7 d when it dropped again. Conclusion During renal development, Wnt4 proteins were involved in the development of the nephrogenic zone through regulating canonical Wnt/β-catenin signaling pathway, and was involved in extension of proximal tubules by inducing the non canonical Wnt/PCP signaling pathway. Expression of Wnt4 protein in rat kidney was closely related to nephron formation and development of proximal tubules.

Telomeres are protective caps located at the ends of human chromosomes. Telomeres shorten with each successive cell di-vision in normal human cells, whereas they are continuously elongated by human telomerase in over 85%of tumors. This simple and attractive difference steers the development of anticancer drugs targeting telomeres and telomerase. Many promising current telo-mere/telomerase-targeting agents, such as GRN163L and GV1001, showed good therapeutic effect both in preclinical studies and phaseⅠ/Ⅱclinical trials. These agents have even entered phaseⅢclinical trials in patients with various tumors. Most therapeutics are more effective when used in combination with standard chemotherapies. Moreover, pharmacological interference with tumor-cell telomere biology to reduce telomere length and/or telomere stability could enhance the effectiveness and safety of radiotherapy. Therapeutics targeting telomere/telomerase may play a key role in radiotherapy in the era of personalized medicine in the future.

BACKGROUND:Hypoxic death limits application of cells in transplantation and tissue regeneration.
OBJECTIVE:To investigate the protective effects of mangiferin on bone marrow-derived mesenchymal stem cells against hypoxia injury-induced apoptosis resulted from cobalt chloride.
METHODS:Rat bone marrow-derived mesenchymal stem cells were in vitro cultured and hypoxia cellmodel was established by cobalt chloride. Model cells were treated with mangiferin. Protective effects of mangiferin were detected using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide;cellapoptosis and mitochondrial membrane potential were detected using flow cytometry.
RESULTS AND CONCLUSION:Cobalt chloride significantly inhibited growth of bone marrow-derived mesenchymal stem cells in a dose-dependent manner. The apoptosis rate of cells was (42.49±3.96)%after treated with 200μmol/L cobalt chloride for 12 hours, (46.37±4.49)%after treated for 24 hours. With increasing concentration of mangiferin, apoptosis of bone marrow-derived mesenchymal stem cells in hypoxic model was gradual y reduced (P<0.01), indicating that mangiferin has a protective effect in a concentration-dependent manner on rat bone marrow-derived mesenchymal stem cells in hypoxic injury. Cobalt chloride can induce hypoxic model successful y in bone marrow-derived mesenchymal stem cells. There are some advantages of accurate dose control, no special equipment requirements, and easy operation. Mangiferin can effectively inhibit bone marrow-derived mesenchymal stem cells apoptosis under hypoxic injury.

Objective:The purpose of this study is to evaluate the effects of a single-chain antibody against death receptor 5 (ZF1) on tumor growth and survival in murine H22 hepatocellular carcinoma tumor model.Methods:Killing effect of ZF1 on H22 cells was analyzed by MTT assay in vitro. The apoptosis rate of H22 cells induced by ZF1 was detected using Flow Cytometry assay. The transplanted model of H22 tumor was developed in mice. The mice were randomly divided into four groups, PBS group, ZF1 group, EPI group and combined treatment group of ZF1/EPI. Tumor growth and body weight changes were observed. After treatment over 13 days, the tumor tissue for HE staining and TUNNEL assay was performed to detect apoptosis.Results:The results showed that ZF1 could inhibit growth of H22 cells in a dose dependent manner. The growth inhibition rate was up to 84.5%. The results showed that ZF1 alone or in combination with ZF1/EPI, the tumor growth was significantly inhibited. HE staining and TUNNEL analysis showed that ZF1 could effectively induce apoptosis of tumor cells without toxic effects, especially in ZF1/EPI combined treatment group.Conclusion:It is showed that ZF1 induces a good inhibition on the proliferation of H22 cell, especially in combined treatment group of ZF1/EPI.
