Chinese Journal of Trauma 1993;0(05):-
Objective To study the expression changes of matrix metalloproteinases (MMPs), protein kinase C (PKC) and nuclear factor-?B (NF-?B ) on the injured rabbit vascular smooth muscular cells (VSMC) transfected with tissue inhibitor of metalloproteinase-2 (TIMP-2) vector. Methods Lipofectin method was used to transfect TIMP-2 vector into VSMC, Western blot analysis to detect TIMP-2 peptides and zymography assay to determine MMPs. The activities of MMPs and NF-?B were detected by electrophoretic mobility shift assay (EMSA). The mRNA and protein expressions of PKC? were determined by RT-PCR and immunocytochemistry. Results The injured VSMC showed increased enzyme activity of MMP-2. There was very lower level expressions of PKC? and NF-?B in the normal VSMC but high in the injured VSMC. However, in injured VSMC transfected with TIMP-2 vector, the activity of MMP2/9 was suppressed and the expressions of PKC? and NF-?B decreased (P

Objective To construct the endothelial cell model with overexpressed human protein kinase C ?2(PKC?2) after high glucose inducement in order to study the function of human PKC?2. Methods The PRKCB1 gene was amplified from pMD18-T-PRKCB1 plasmid and then directly cloned into shuttle plasmid pDC315 to construct shuttle plasmid. Then the recombinant shuttle plasmid and adenovirus genomic plasmid pBHGlox△E1,3Cre were cotransfected into 293 cells to construct recombinant adenovirus Ad-PRKCB1. The virus titer was calculated by TCID50. The Ad-PRKCB1 was verified by immunocytochemistry and RT-PCR. Ad-PRKCB1 was transfected into human umbilical vein endothelial cells (HUVECs) followed by the treatment of high glucose (25 mmol/L) for 96 h, and then the cells were observed by laser scanning confocal microscopy (LSCM). Results Restrictive endonuclease digestion and PCR result showed that the target gene was correctly cloned into shuttle plasmid. Cytopathic effect (CPE) was observed under inverted microscope through homologous recombination. The virus titer was 7.9?109 IU/ml. Immunocytochemical staining and RT-PCR indicated the expression of human PKC?2 in the transfected HUVECs. The translocation was observed under LSCM. Conclusion A recombinant adenovirus vector with human PKC?2 and the endothelial cell model with human PKC?2 overexpression by high glucose are constructed successfully.

Objective To investigate the role of local aldosterone system in oncofetal fibronectin ( oncofetal FN) mRNA expression and reactive oxygen species (ROS) production in human mesangial cells (HMCs) exposed to short-term intermittent high glucose and the effect of Fenofibrate.Methods The HMCs were divided into 8 groups:normal glucose(NG) ;osmotic fluctuation(OF) ;mean glucose load (MGL) ;stable high glucose (SHG),short-term intermittent high glucose (IHG) ; intermittent high glucose plus eplerenone (IHGE) ; intermittent high glucose plus fenofibrate(IHGF) ; and normal glucose plus fenofibrate (NGF) groups.The mRNA expression levels of Aldosterone synthase ( CYP11 B2 ),11 β-hydroxysteroid dehydrogenase type 2 ( 11βHSD2 ) and oncofetal FN were determined by RT-PCR.The expression of CYP11B2 protein was determined by western-blot.Aldosterone level in cell culture supernatant was detected by radioimmunoassay.The expression and translocation of mineralocorticoid receptor (MR)protein were assayed with confocal laser scanning microscopy. ROS levels were determined by Fluorescence microscopy and fluorescence microplate reader.Results ( 1 ) MGL,SHG,and IHG groups showed a 2.41,3.63,and 4.45 times increase in CYP11B2 mRNA expression,and a 1.83,2.15,and 2.78 times increase in CYP11B2 protein expression,respectively,compared with NG group (P < 0.05 ).The aldosterone levels of HMCs culture supernatant in MGL,SHG,and IHG groups were also increased,being 1.49,2.04,and 2.54 times of that in NG group ( P<0.05 ),and the degree of elevation in IHG group was more marked than that in SHG group( P<0.05 ).MR was activated and translocated from cytosol to nucleus in MGL,SHG,and IHG groups.Quantitative analysis showed the ratioes of cytosol/nucleus fluorescence intensity in MGL,SHG,and IHG groups were 15%,38%,and 53% decreased as compared with that in NG group,and the decrease was more marked in IHG group ( P<0.05 ).(2) Oncofetal FN mRNA expression and ROS levels in MGL,SHG,and IHG groups were increased,being 1.54,2.31,3.65 and 1.26,1.91,2.48 times of those in NG group,respectively ( P<0.05 ),and this increase was more marked in group IHG ( P<O.05 ).Compared with IHG group,oncofetal FN mRNA expression and ROS levels in group IHGE were significantly decreased by 54% and 53%,and in group IHGF by 45% and 39%. ( 3 ) CYP11B2 mRNA,protein,and aldosterone levels in IHGF group were decreased by 74%,59%,and 50%,and the activation of MR in group IHGF was inhibited when the ratio of cytosol/nuclear fluorescence intensity was increased 1.88 fold as compared with that in group IHG ( P<0.05 ).Conclusions Increased expressions of oncofetal FN and ROS by HMCs induced by short-term intermittent high glucose were nore marked than those induced by stable high glucose.The mechanism was associated with activation of local aldosterone system.Fenofibrate may inhibit the activation of local aldosterone system and alleviate the injury to HMCs induced by intermittent high glucose.

Objective To analyze the correlation between 18F-FDG SUV and immunohistochemical index including GLUT1, Ki-67, MVD, survivin and cyclinA in non-snall-cell lung cancer. Methods Thirty-three patients with NSCLC underwent preoperative PET/CT examination and surgical operation. All patients were divided into two groups according to the size of tumor (cutoff=3 cm), metastasis of mediastinal or hilar lymph nodes or not, and histological types of the cancer, respectively. The expression of GLUT1, Ki-67, MVD, survivin and cyclinA were estimated with SP immunohistochemical technique, and were analyzed statistically to reveal the correlation to FDG SUV. Results The rate of positive expression of GLUT1, Ki-67 and CD34 were 66.67%, 72.73% and 100%, respectively. The mean value of CD34 in all 33 patients was 12.6±2.9 (12-56). The rate of positive expression of survivin was 84.85%, and the corresponding data of cyclinA was 27.27%. Conclusion There is linear correlation between FDG PET SUV and GLUT1, but not between FDG PET SUV and Ki-67, MVD, survivin and cyclinA. The expressions of GLUT1, Ki-67, MVD, survivin and cyclinA are not related with the size of tumor, nor metastasis of lymph nodes. The expression of GLUT1 and Ki-67 is related with histological types of the cancer, but not with MVD, survivin and cyclinA.
