2.Advances on correlation between Girdin protein and breast cancer
Practical Oncology Journal 2016;30(1):57-60
Girdin protein is a kind of actin binding protein,which has the complex molecular structure and takes part in a variety of signaling pathways related with causing cancer.The biological characteristics of Gir-din protein have close association with the proliferation and invasion of malignant tumor.Recent studies have shown that Girdin protein is closely related with occurrence and progress of breast cancer.Girdin protein expres-sion in breast cancer cells can not only promote the progress of breast cancer,but also affect the lymph node me-tastasis and prognosis.Therefore Girdin protein is expected as an independent biomarker to provide a new direc-tion for breast cancer treatment.

6.Correlation of NDRG1 gene with liver tissue differentiation and hepatocarcinogenesis
Journal of Peking University(Health Sciences) 2003;0(05):-
Objective: To detect the expression profile of NDRG1 gene in different tissues and cell lines and explore the relationship of NDRG 1 with liver tissue differentiation and hepatocarcinogenesis. Methods: The expression profiles of NDRG 1 in hepatocellular carcinoma (HCC) tissues, paired noncancerous liver (PNL) tissues, adult normal liver (NL) tissues, baby mouse liver tissues and fetal liver tissues in different developmental stages and cultured cell lines were performed using RT PCR and Northern Blot analysis. Results: Expression of NDRG 1 was significantly up regulated in HCC tissues compared to that of NL tissues and PNL tissues, however, the expressions of NDRG1 in NL and PNL tissues showed no evident difference. In ten cell lines, the highest expression was in the 293T human kidney cell line, the next one in liver cell L02, and the lowest one in the undifferentiated HLE cell line. Expression of NDRG1 in liver tissues enhanced with the development of the baby mouse and human fetus. Conclusion: NDRG 1 is probably related to the liver cell differentiation and is highly expressed in the specific stage of the differentiation. However, it could not be recognized as a marker of differentiation. The high expression of NDRG 1 in HCC indicates that HCC is not just distributed to a simple de differentiation. Much more study is necessary in understanding the comprehensive relationship of the disorder proliferation and differentiation of HCC and the related genes.
7.Improving Effect of Traditional Chinese Medicine on Diabetic Nephropathy via Regulating MCP-1 and TNF-α
China Pharmacist 2017;20(3):534-537
Diabetic nephropathy ( DN) is one of the complications of diabetes, which is closely related to the pathogenesis of in-flammation. This article summarized the relevant literatures on the correlation between MCP-1 , TNF-α and DN, and the intervention of traditional Chinese medicine with DN. In kidney tissues, oxidative stress and NF-κB-dependent signal pathways induced the increase of monocyte chemoattractant protein-1 (MCP-1) expression, which could induce macrophage accumulation, proteinuria increase, renal fibrosis and renal clearance capacity decrease, and further leading to kidney damage. The clinical and experimental trails showed tumor necrosis factorαmRNA and protein levels in serum, urine and renal tissues were closely related with DN, which could be used as a bio marker to provide clinical guidance. As the therapeutic targets,MCP-1 and TNF-αcould give a novel insight into the clinical treatment of DN. Some traditional Chinese medicines or monomer could ameliorate DN by inhibiting MCP-1 and/or TNF-α. Thus, further verifi-cation or clinical application of those traditional Chinese medicines is worth trying.

Chinese Journal of Biochemical Pharmaceutics 2017;37(4):317-319
Objective To investigate the effects of serum MMP-9,MMP-2 and inflammatory factor levels by intensive lipid-lowering therapy in patients with acute myocardial infarction.Methods A total of 76 cases with acute myocardial infarction from May 2012 to October 2016 in our hospital were collected and randomly divided into control group and experiment group with 38 cases in each group.Patients in the control group were treated by clinical routine lipid-lowering(simvastatin 20mg/day); patients in the experiment group were treated by clinical intensive lipid-lowering(simvastatin 80mg/day),treated for two weeks.Observed the serum MMP-9,MMP-2 and inflammatory factor levels changed of the two groups before and after treatment,explored the validity and security of intensive lipid-lowering therapy in the treatment of patients with acute myocardial infarction.Results After treatment,the clinical efficacy of the experiment group was better than control group,performanced as: the serum MMP-9 and MMP-2 levels of the experiment group were more lower than the control group; the serum hs-CRP,TNF-αand IL-6 levels significant lower than the control group,the above results had statistical significance(P<0.05).The adverse reactions of the experiment group were slight,back to normal after stopped drugs.Conclusion Intensive lipid-lowering therapy in the treatment of patients with acute myocardial infarction can significantly reduce serum MMP-9 MMP-2 and inflammatory factor levels,and high safety.
9.miR-486 is a tumor suppressor in glioma stem cells
Chinese Journal of Tissue Engineering Research 2015;(41):6633-6637
BACKGROUND:Previous studies have found that the expression level of miR-486 in glioma stem cels (CD133+) is significantly down-regulated compared with that in glioma non-stem cels (CD133-), but the effect of down-regulation of miR-486 on CD133+ cels remains unclear . OBJECTIVE: To explore the effect of miR-486 on CD133+ cels. METHODS:CD133+ glioma stem cels and CD133- glioma cels were separated from U87 cels by flow cytometer. miR-486 overexpression glioma stem cels were constructed by lipofection transfection. RESULTS AND CONCLUSION:After sorting and purification, the content of the CD133+ fraction was enriched up to 83.5%. The expression level of miR-468 in CD133+ glioma stem cels was obviously down-regulated compared with that in CD133- glioma cels. CD133+ glioma stem cels overexpressing miR-486 were fabricated successfuly. Results from in vitro experiments showed that miR-486 overexpression could dramaticaly decrease the proliferation of glioma stem cels, induce a cel cycle arrest in G1/S phase for CD133+ glioma stem cels and promote cel apoptosis. These findings suggest that miR-486 can be a suppressor of glioma stem cels, which offers a novel potential therapeutic target for glioma stem cels and human glioma.
10.The regulation of Cathepsin B on cell apoptosis induced by SAHA in breast cancer cell line MCF-7
Chinese Pharmacological Bulletin 2016;32(8):1086-1090
Aim To clarify the regulation role of ca-thepsin B ( Cat B ) in cell proliferation and apoptosis induced by SAHA in ER-positive breast cancer cell line MCF-7.Methods MTT was used to screen the optimal concentration and treatment time of SAHA . The expression levels of related proteins were deter-mined by ELISA , and the morphological changes were observed through time-lapse live cell imaging acquisi-tion.Cell viability and apoptosis assay in MCF-7 cells were assessed by Muse Cell Analyzer with SAHA and /or Cystatin C treatment .Results MTT assay showed that the anti-tumor efficacy of SAHA was significant . The optimal concentration and treatment time were 10μmol? L-1 and 24 h respectively . ELISA assay showed that SAHA could induce expression of Cat B in MCF-7 cells.Real-time live-cell imaging experiments demonstrated that the combination treatment of Cystatin C and SAHA significantly resumed the inhibitory effect caused by SAHA alone .Cytology test showed that SA-HA alone obviously depressed the cell viability and in-duced apoptosis . However , the effect was reversed with the combination of Cystatin C .Conclusion Cat B plays an important role in apoptosis induced by SAHA in ER +breast cancer cells MCF-7.
