Objective To investigate the expression and significance of activator protein-1 (AP-1)and matrix metalloproteinases (MMPs) in acute myocardial infarction (AMI) subjects. Methods Immunohistochemical techniques were used to detect the subunit of AP-1 (c-Jun), MMP-2 and MMP-9 in human AMI and normal heart tissue and the expressions of c-Jun and MMPs were measured with computer image analysis system. Results (1) There were expressions of c-Jun, MMP-2 and MMP-9 in normal heart tissue, mainly in myocardial cells and cardiac fibroblasts, and their expressions in AMI myocardial tissues were all significantly higher than those in normal myocardial tissues (P <0.05). (2) The level of MMP-9expression was significantly and positively correlated with c-Jun in AMI heart tissue (r=0.773, P < 0.01).Conclusions The expressions of AP-1 and MMPs increase in human myocardial infarction. These findings suggest that AP-1 transcription activation pathway and MMPs may play an important role in ventricular remodeling of myocardial infarction.

OBJECTIVE:To study t he effects of bro mophenylcurcumin(GL63)on the apoptosis ,migration and invasion of human cholangiocarcinoma RBE cells ,and to investigate its mechanism based on JAK/STAT signaling pathway. METHODS :MTT assay was used to detect the effects of different concentrations of GL 63 [0(blank control ,similarly hereinafter ),1.25,2.5,5,10, 20,40 μ mol/L] on the proliferation of RBE cells after 48 h treatment ;the IC 50 was calculated. The effects of different concentrations of GL 63(0,5,10,20 μmol/L)on colony formation were detected by crystal violet staining after 48 h treatment. Flow cytometry ,Hoechst 33342 staining,cell scratch test and Transwell chamber invasion test were used to detect the effects of different concentrations of GL 63(0,5,10,20 μmol/L)on cell cycle distribution ,apoptosis,migration and invasion ability after 24 h treatment. Western blotting assay was adopted to detect the effects of different concentration of GL 63(0,5,10,20 μmol/L) on the expression of JAK 2/STAT3 signal pathway associated proteins. RESULTS :The proliferation inhibition rates of RBE cells in different concentrations of GL 63 groups(1.25-40 μmol/L)were significantly increase d,compared with blank control group (P< 0.01),and showed a dose-dependent trend ,with IC 50 of (8.46±1.30)μmol/L. Compared with blank control group, 85917439。E-mail:zhaoji-an-88@163.com inhibition rates of RBE cell colony formation were significantly decreased in different concentrations (5,10,20 μmol/L)of GL 63 groups(P<0.01). The percentage of RBE cells at G 0/G1 phase increased significantly ,while that at S phase decreased significantly (P<0.01). The apoptotic rate increased significantly(P<0.01),and the nucleus showed dense pyknosis and apoptotic bodies. The rate of cell migration and healing was significantly decreased (P<0.01),and the number of invasive cells through basement membrane was significantly decreased (P< 0.01). The protein expression of p-JAK 2, p-STAT3, Bcl-2, MMP-2, MMP-9, Pro-caspase-9 and P ro-caspase-3 were down-regulated significantly while the expression of Bax ,Cyt-c,Cleaved-caspase-9 and Cleaved-caspase- 3 were up-regulated significantly(P<0.01). CONCLUSIONS :GL63 may inhibit the proliferation ,migration and invasion of RBE cells and promote its apoptosis by inhibiting JAK 2/STAT3 signal pathway.
