The Effects Of JAZF1Gene Inhibits In AKT And AMPK Signaling Pathway On Giucose And Lipid Metabolism | | Posted on:2013-05-21 | Degree:Master | Type:Thesis | | Country:China | Candidate:L Du | Full Text:PDF | | GTID:2234330374477864 | Subject:Clinical Laboratory Science | | Abstract/Summary: | PDF Full Text Request | | Objective: To establish the mice JAZF1-shRNA expression vectorand construct the cell model of JAZF1gene inhibition.Methods: JAZF1shRNA sequence were designed and synthesized.Select pGenesil-1.2carrier and mU6promoter to build pGenesil-JAZF11,2,3inhibit the plasmid. Transfected into the mice hepa1-6cells,quantitative PCR technique were used to screen the best inhibition ofplasmid. The effect was determined in3T3-l1cells.Result: The three recombinant plasmids of pGenesil-JAZF1wereconstructed successfully. The pGenesil-JAZF1-3inhibition of plasmid wasscreened for the best suppression fragment,and inhibition rate is78-84%inhepa1-6cell and37-42%in3T3-L1cells.Conclusion: JAZF1-shRNA recombinant plasmid Was successfullyconstructed, and the best efficiency was identified. Objective: To observe the effect of JAZF1suppression onglycolipids metabolism of adipocyte and hepatocytes.Method:3T3cells and Hepa1-6cells were transfected with mostefficiency pGenesil-JAZF1-3plasmids, cell immunofluorescence wereemployed to detect glycometabolism related protein expression, Westernblot and cell immunofluorescence were used to detect glycolipidsmetabolism related protein level.Glycometabolism targets were detectedusing real-time PCR,Triglyceride level of3T3cells after transfection wasassessed by oil red O stain,H3tracing was used to assess carbohydrateuptake rate.Results: GLUT1and GLUT4mRNA was upregulated afterpGenesil-JAZF1-3transfection(P<0.05),protein level of GLUT1andG-6-Pase were upregulated but didn’t reach statistics significance, PEPCKwas upregulated (P<0.05);HSL and PPAR-γ was upregulated but didn’treach statistics significance。In3T3cells, GLUT1and GLUT4mRNA wasdownregulated after pGenesil-JAZF1-3transfection(P<0.05),GLUT1and GLUT4mRNA was upregulated but didn’t reach statistics significance;pGenesil-JAZF1-3transfected showed lower expression of HSL(P<0.05)and higher expression of PPAR-γ;Visfatinã€Acrp30and Insig-2weredownregulated after pGenesil-JAZF1-3transfection(P<0.05). Conclusion: JAZF1gene silence reduced basic carbohydratetransport,raised synthesis of lipide and cholesterol, cytokine related to fatdesintegration was downregulated at the same time. Objective:To study on the signal pathway that related to theglycolipids metabolism, identify effect of JAZF1suppresion onglycolipids metabolism.Methods:Protein targets on signal pathway that related to theglycolipids metabolism were assesed using Western blot technology.Results:P-AKT and P-AMPK of Hepa1-6after JAZF1silence wasno changed. AKT/PKA/HSL lipid metabolism signal and AMPK/TORC2glycometabolism signal were inhibited after JAZF1silence in3T3cells(P<0.01).Conclusion:The inhibition of JAZF1gene was a important factor insignal pathway of glycolipids metabolism,which increase the risk ofdiabetes. JAZF1gene may promote glucose and lipid metabolismsignaling pathway in the phosphorylation as an important factors. | | Keywords/Search Tags: | JAZF1, shRNA, pGenesil, Hepa1-6, 3T3-L1JAZF1, Gene silence, 3T3-L1, glycolipidsMetabolismJAZF1, AKT, AMPK, signal pathway | PDF Full Text Request | Related items |
