AIM:To explore the regulatory effect of microRNA-3666 (miR-3666) on the expression of its tar-get gene phosphatase and tensin homologue deleted on chromosome ten (PTEN) in leukemic cells.METHODS: miR-3666 expression levels in normal peripheral blood mononuclear cells and leukemic cells were determined by quantitative real-time PCR.miR-3666 targeting PTEN 3'-untranslated region (3'UTR) was predicted by TargetScan software .3'UTR of PTEN was inserted in the dual luciferase reporter vector psiCHECK 2.The reporter activity was evaluated by the Dual-Lu-ciferase Reporter Assay System after the luciferase promoter vector and miRNA were co -transfected into HEK293T cell line. K562 cells were transfected with synthetic miR-3666 inhibitor ( anti-miR-3666) or a synthetic control miRNA ( anti-miR-C) .The expression of PTEN protein in the above transfected K 562 cells was determined by Western blotting .RESULTS:miR-3666 was up-regulated in the human leukemic cell lines and primary leukemic cells compared to normal peripheral blood mononuclear cells .The results of dual luciferase assays validated PTEN as a specific target gene of miR-3666.Inhi-bition of miR-3666 resulted in an up-regulation of PTEN protein expression in the K 562 cells.CONCLUSION:miR-3666 is over-expressed in leukemic cells .The abnormal over-expression of miR-3666 may play a key role in leukemia due to the down-regulation of PTEN .

Objective To observe the effect of curcumin on the expression of smad7 and TGF-β1 in rats renal tubular cells of with Ang II, and discuss the mechanism of curcumin to improve renal interstitial fibrosis.Methods Cultured rat renal tubular epithelial cells were divided into the blank group, the Ang II control group and the low, medium and high dose curcumin group. The rest of the groups were intervened by 10-8 mol/L Ang II except the blank group; the low, medium and high dose groups of curcumin were intervened by 2.5, 5.0, 10.0μmol/L curcumin. Then Western blot was used to detect the expression of TGF-β1 and smad7 protein, RT-PCR was used to detect the TGF-β1 and smad7 mRNA expression.Results Compared with the blank group, the expression of TGF-β1 protein (0.23 ± 0.03vs. 0.16 ± 0.01), and TGF-β1 mRNA (1.89 ± 0.20vs. 1.00 ± 0.00) significantly increasedin AngⅡ control group (P<0.05), and the expression of smad7 protein (0.19 ± 0.03vs. 0.24 ± 0.02), and smad7 mRNA (0.48 ± 0.05vs. 1.00 ± 0.00) significantly reduced in AngⅡcontrol group (P<0.05). Compared with the AngⅡ control group, the expression of TGF-β1 protein in low, medium and high dose curcumingroup (0.18 ± 0.02, 0.17 ± 0.02, 0.16 ± 0.03vs. 0.23 ± 0.03) and TGF-β1 mRNA (1.58 ± 0.11, 1.34 ± 0.16, 0.97 ± 0.19vs. 1.89 ± 0.20) significantly decreased (P<0.05), and the expression of smad7 protein (0.28 ± 0.04, 0.31 ± 0.03, 0.34 ± 0.04vs. 0.19 ± 0.03) and smad7 mRNA (0.68 ± 0.07, 0.80 ± 0.06, 0.98 ± 0.09vs.0.48 ± 0.05) increased significantly (P<0.05).Conclusions Curcumin can thus play its role in renal protection by counteract the AngⅡ mediated renal interstitial fibrosis. Its mechanism may be related to the reduction of TGF-β1 protein and its mRNA expression, up regulation of smad7 protein and its mRNA expression.
