DING Hai-feng, CAO Yong-bing, AN Mao-mao, JIA Xin-ming, JIANG Yuan-ying
2011, 29(2): 89-92,116.
Abstract(2969)
Abstract:
In the last few years, inhibitors of the type 2 sodium glucose co-transporters (SGLT2) had been the subject of novel approach to treating diabetes. SGLT2 played a major role in physiology of glucose reabsorption from proximal part of kidney. The blockade of SGLT2 in the kidney had the potential to prompts urinary excretion of glucose and promotes normalization of blood glucose without hypoglycemia in the setting of type 2 diabetes. Clinical trails showed that their efficacy in the treatment of type 2 diabetes was promising; Weight loss and very low risk of hypoglycemia were the potential benefits of these inhibitors. Some of these inhibitors had been developed and advanced to late phase clinical testing.

Abstract(2899)
Abstract:
Objective To express and purify the human ribosomal protein S3a and study the subcellular localization of human ribosomal protein S3a. Methods The RPS3a gene was obtained by RT-PCR, total RNA extracted from human HEK293 cell as the template,and cloned into the prokaryotic expressing vector PET-21a to form PET21a-RPS3a, then transferred into (Escherichia coli)BL21(DE3). PET21a-RPS3a was highly expressed in (Escherichia coli)BL21(DE3) in the presence of isopropyl-β-D-thiogalactopyranoside (IPTG) and most products existed in a soluble form. After ultrasonication, recombinant fusion proteins were purified by Ni2+-NTA affinity chromatography and 50 kD ultrafiltration membrane, the purity of RPS3a was further confirmed by Western Blot analysis. The full sequence of RPS3a gene was recombined in the downstream of the green fluorescent protein gene in the EGFP-N1 vector.The recombined pEGFP-N1-RPS3a vector was transfected into human kidney epithelial cells (293 cells), through the subcellular localization, which was observed RPS3a recombinant fluorescent protein in the cell distribution. Results The higher purity of recombinant fusion protein was obtained. Subcellular localization analysis confirmed that RPS3a recombinant fluorescent protein distributed mainly in the cytoplasm. Conclusion The recombinant fusion protein PET21a-RPS3a was successfully cloned, expressed, purified. Application of subcellular localization raises the foundation to the study on nature and function of human RPS3a protein.

Abstract(2349)
Abstract:
Objective To investigate the effects of pravastatin on nitric oxide production in endothelial progenitor cells. Methods Total mononuclear cells(MNCs) were isolated from peripheral blood by Ficoll density gradient centrifugation,and cultured in vitro. After 7 days of culture, attached cells were stimulated with pravastatin (10 and 100 μmol/L) for 48 h. The cells were identified by immuno-histochemistry and flow cytometry and tested the ability to intake the acLDL. The content of NO and the level of endothelial nitric oxide synthase ( eNOS) mRNA were tested. Results Compared with control group, the content of NO and the level of eNOS of pravastatin group increased obviously (P<0. 05). Conclusions Pravastatin could increase the production of nitric oxide and the expression of eNOS mRNA in EPCs, which could improve blood vessel endothelium function.
