The cell killing effects and bystander effects of double suicide gene on pulmonary carcinoma cells were explored. Lung adenocarcinoma cells (A549) were transfected with different titers of adenovirus vector and followed with different concentrations of 5-FC after a recombinant adenovirus vector carrying CD/UPRT gene (Ad-CD/UPRT) was constructed. The cell viability was measured by MTT assay 4 days later. The cell viability was dropped to 30.57 %-8.62 % after 10 MOI of Ad-CD/UPRT transfected and 5-FC (10-1000 microg/mL) administration. Furthermore, Ad-CD/UPRT-infected A549 cells showed a profound neighbor cell killing effect in the same methods. These results suggested that Ad-CD/UPRT/5-FC system can effectively suppress growth of lung adenocarcinoma cells, which may provide a novel and powerful candidate for lung cancer gene therapy strategies.

Based on the transcriptome data, we cloned the open reading frame of IiHCT gene from Isatis indigotica, and then performed bioinformatic analysis of the sequence. Further, we detected expression pattern in specific organs and hairy roots treated methyl jasmonate( MeJA) by RT-PCR. The IiHCT gene contains a 1 290 bp open reading frame( ORF) encoding a polypeptide of 430 amino acids. The predicted isoelectric point( pI) was 5.7, a calculated molecular weight was about 47.68 kDa. IiHCT was mainly expressed in stem and undetectable in young root, leaf and flower bud. After the treatment of MeJA, the relative expression level of IiHCT increased rapidly. The expression level of IiHCT was the highest at 4 h and maintained two fold to control during 24 h. In this study, cloning of IiHCT laid the foundation for illustrating the biosynthesis mechanism of phenylpropanoids in I. indigotica.

OBJECTIVETo observe the effect of six common Chinese medicinal herbs for promoting blood circulation, including Radix Paeoniae rubra (I), Radix Salviae miltiorrhizae (II), Rhizoma Chuanxiong (III), Radix Notoginseng (IV), Semen Persicae (V) and wine steamed Radix et Rhizoma Rhei (VI), on blood lipids and inflammatory reaction of atherosclerotic plaques in ApoE gene deficiency mice.

METHODSNinety mice, 6 - 8 weeks old, were divided into 8 groups, the model group, the control group (treated with simvastatin) and the six treated groups treated with the above-mentioned 6 Chinese medicinal herbs respectively. All the mice were fed with the diet of western kind for 13 weeks until the mature atherosclerotic plaques formed in them. Then they were treated with respective drugs for another 13 weeks except those in the model group. All the mice were sacrificed at the end of experiment, their blood was collected for lipids determination, heart and aorta were taken out for determining the level of CD68 in root of aorta, as well as the expressions of monocyte chemotactic protein-1 (MCP-1) and tumor necrosis factor-a (TNF-a) by immunohistochemistry staining.

RESULTSAll the 6 Chinese herbs showed regulatory action on blood lipids. The positive expression of CD68 in the model group displayed the highest activity. As compared with the model group, the CD68 positive expressed cells in the control group and the groups treated with Chinese herbs II, III, and IV were lesser (P < 0.05), and the expression of inflammatory factors (MCP-1 and TNF-alpha) in atherosclerotic plaques was significantly lower in the control group and the group treated with Chinese herb VI (P < 0.05).

CONCLUSIONChinese medicinal herbs tested in this study can interfere the maturing progress of atherosclerotic plaques and stabilize the plaques in ApoE deficiency mice, the mechanisms may relate to its actions in regulating lipids metabolism and inhibiting inflammatory reaction. Different Chinese medicinal herbs for activating blood circulation of conventional dosage might show difference in potency and acting links.
