AIM: To investigate the contribution of angiotensin-converting enzyme inhibitor (ACEI) to the regulation of calpain system in infarcted myocardium. METHODS: Rat myocardial infarction (MI) model was established by permanent ligation of the left coronary artery. The treatment with the ACEI inhibitor rampril (1 mg·kg-1·d-1) was started 7 days prior to surgery. On day 1, 3, 7 and 14 after MI, protein levels of calpainⅠ, Ⅱ and calpastatin were determined in left ventricular free wall (LVFW), interventricular septum (IS) and right ventricule. RESULTS: CalpainⅠprotein level was increased in IS 14 d post MI, whereas the protein level of calpainⅡ was maximally increased in LVFW 3 d post MI. Rampril decreased protein up-regulation of calpainⅠ and Ⅱ, and reduced infarct size and interstitial fibrosis. Calpastatin protein expression was not affected by ACEI. CONCLUSIONS: CalpainⅠ is involved in cardiac remodelling in the late and calpainⅡ contributes to cardiac tissue damage in the early phase of MI. The heart protective effect of ACEI may be related to the inhibition of calpain system in the pathogenesis of myocardial infarction.  相似文献   

Increased expression of CD40 ligand by peripheral blood mononuclear cells in patients with systemic lupus erythematosus

AIM:To investigate expression and function of CD40 ligand by peripheral blood mononuclear cells (PBMCs) in patients with systemic lupus erythematosus (SLE).METHODS:Expression of CD40 ligand by PBMCs in patients with SLE and control were examined by flow cytometric analysis before and after stimulated by phytohemagglutinin(PHA)and depressed by Dexamethasone(Dex). The correlation between expression of CD40 ligand and SLE activity index(SLEDAI) was analysed in patients with SLE.RESULTS:The expression of CD40 ligand by PBMCs in patients with active SLE was higher than that in patients with inactive SLE and control. Though the expression of CD40 ligang by PBMCs could be stimulated by PHA in three groups, it was the highest in patients with active SLE. Dex depressed the expression of CD40 ligand by PBMCs significantly in patients with SLE, but not in control. There was high positive correlation between expression of CD40 ligand and SLEDAI in patients with active and inactive SLE.CONCLUSION:Increased expression of CD40L by PBMCs in patients with SLE may play an important role in pathogenesis of SLE.  相似文献   

Association of polymorphism of Fc receptor γ chain gene at position-29 in promoter with the susceptibility to systemic lupus erythematosus in southern Chinese     

ZHOU Shu-lu  YE Ren-gao  LIU Xiao-bo  ZHANG Hong  XU Han-shi  DU Yong  LI You-ji  YANG Nian-sheng  YANG Xiao  YU Xue-qing 《园艺学报》2003,19(6):782-785

AIM:To detect the association between the polymorphism of Fc receptor γ chain gene at position-29 in promoter and systemic lupus erythematosus(SLE).METHODS:The genotypes at position -29 in promoter of Fc receptor γ chain gene were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method in 180 patients with SLE and 140 ethnically matched controls in southern China.RESULTS:The frequencies of TT genotype(33.3%) and T allele (54.4%) at position -29 in patients with SLE were significantly higher than those in controls (17.2% and 42.9%, respectively), whereas, the frequencies of GG genotype (24.4%) and G allele (45.6%) in patients with SLE were remarkably lower than those in controls (31.4% and 57.1%, respectively) (P＜0.05). The TT genotype and T allele at position -29 were not associated with lupus nephritis in SLE patients (P＞0.05).CONCLUSION:Our results indicate that the T allele at position -29 in promoter of Fc receptor gene probably contributes to the susceptibility to SLE, but does not play a role in the occurrence of lupus nephritis.  相似文献   

Cloning of p15^INK4b related gene CCRG and expression analysis in the renal carcinoma     

JIN Gui-hua  YE Xiong-jun  CHANG Zhi-jie 《园艺学报》2003,19(10):1300-1304

AIM and METHODS:To analysis the factor that involved in renal carcinogenesis, we used the bait gene AK001518 to screen GenBank. To understand the relationship between cell cycle related gene(CCRG) and p15, we did RT-PCR and Northern Blot experiments. Then we examined CCRG expression level in renal carcinogenesis. RESULTS:Gained a function unknown gene CCRG that was 67% a mino acid identical with the gene AK001518 that was regulated by p15. It was shown that the CCRG mRNA was dramatically decreased when p15 gene was over-expressed. CCRG expression level was much higher in tumor tissues and cells than normal tissues and cells. CONCLUSION:The novel gene CCRG expressed highly in the renal carcinoma, which might play a significant role in the renal carcinogenesis.  相似文献   

Expression and role of CD134 and NF-κB in renal tissue of lupus nephritis     

ZHOU Yan-bin  YE Ren-gao  XIE Can-mao  XU Han-shi  GUAN Wei-ming  YANG Xiao  YANG Nian-sheng 《园艺学报》2003,19(9):1221-1223

AIM:To investigate the role of CD134 (OX40) and NF-κB in the pathogenesis of lupus nephritis (LN).METHODS:Renal in situ CD134 and NF-κB expression were examined in 40 biopsy specimens from LN patients by immunohistochemistry and microwave-based immunohistochemistry, respectively. The relationship between expression of CD134 and NF-κB was analyzed.RESULTS:The expression of glomerular and tubular CD134 and NF-κB in LN were higher than that in normal control, especially in class Ⅳ LN, where there was intense staining of endothelial cell, distal tubules, and interstitial mononuclear cell. The CD134 expression of glomerular and tubular was closely related to NF-κB expression, respectively (r=0.5542, P＜0.05;r=0.6279, P＜0.05). CONCLUSIONS:The abnormal expression of costimulatory molecule CD134 was well evidenced in LN. Strong expression of renal in situ NF-κB was likely mediated by CD134 signal pathway, which may play an important role in the pathogenesis of LN.  相似文献
