The occurrence and development of lung cancer are closely related to gene expression and mutations.Recent studies of lung cancer related genes show that the expression of COPS3 gene may play a key role in the lung cancer cell proliferation.Echinoderm microtubule associated protein like 4-anaplastic lymphoma kinase fusion gene and epidermal growth factor receptor mutations coexist.GA733 gene is closely related to lung cancer survival.Fibroblast growth factor receptor 1,high mobility protein family,members of the scavenger receptor class 5 and epidermal growth factor receptor provide new ideas for targeted therapy of lung cancer.For the therapy of lung cancer,multiple gene therapy and gene therapy combined with conventional treatment is required.

Angiopoietin is a novel angiogenesis related molecule. To investigate its roles in tumor angiogenesis and metastasis,angiopoietin 1 gene was obtained from human placental tissue by reverse transcription polymerase chain reaction (RT PCR). The sense, antisense eukaryotic expression vector pcDNA3.1/hangiopoietin1(+), antisense eakaryotic expression vector pcDNA3.1/hangiopoietin1(-), and prokaryotic expression vector pRSETC hangiopoietin1 were successfully constructed by directional cloning the target gene into pcDNA3.1 V5 His C and pRSET C vectors, respectively. This lays good foundation for further study on the roles of angiopoietin 1 in angiogenesis in tumors of the digestive tract.

Objective To analyze the role of cysteinyl aspartate specific proteinase-1 (caspase-1) in a mouse model of D-galactosamine (D-GalN) and lipopolysaccharide (LPS) induced acute liver failure (ALF) and to study the possible mechanism. Methods C57BL/ 6 mice were randomly divided into four groups including control group, Z-WEHD-FMK (caspase-1 inhibitor) treatment group, ALF model group and Z-WEHD-FMK-treated ALF group. The mouse model of ALF was established by intraperitoneally injec-ting the mice with D-GalN (450 mg/ kg) and LPS (10 μg/ kg). The damages in liver tissues were evaluated based on the histopathological examination and the levels of alanine transaminase (ALT) and aspartate trans-aminase (AST) in serum samples. Western blot assay was performed to analyze the expression of caspase-1 and the phosphorylation of glycogen synthase kinase 3β (GSK-3β). The qRT-PCR was used to measure the expression of inflammatory cytokines at transcriptional level. Results The expression of caspase-1 at both mRNA and protein levels were gradually increased during the development of ALF. Compared with the mice with ALF, those in the Z-WEHD-FMK-treated ALF group showed less severe liver damages on histopatholog-ical examination and decreased levels of ALT and AST in serum samples [ALT: (479. 2±39. 5) U/ L vs (998. 5±60. 4 ) U/ L, P<0. 05; AST: ( 478. 5±28. 6) U/ L vs ( 1 180. 7±91. 4) U/ L, P<0. 05]. The expression of TNF-α, IL-1β, IL-18 and IL-33 at transcriptional level were significantly suppressed in mice with ALF upon the Z-WEHD-FMK intervention. Results of the Western blot assay indicated that Z-WEHD-FMK suppressed the activities of GSK-3β by enhancing its phosphorylation. Conclusion This study demon-strated that caspase-1 could promote the activation of GSK-3β resulting in the development of inflammation responses and liver damages during the development of ALF in mice.
