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 investigate the effects of peroxisome proliferator-activated receptor α( PPARα) on macrophage-mediated inflammatory responses with the interference of lipopolysaccharide and the possible mechanism.Methods The bone marrow stem cells were isolated from the femora of mice.The granulocyte-macrophage colony stimulating factor ( GM-CSF) was used to stimulate the in vitro differentiation from bone marrow stem cells into primary macrophages.An in vitro model with cultured cells expressing in-flammatory cytokines was established by treating the primary macrophages with lipopolysaccharide ( LPS) .A specific chemical agonist, Wy-14643, was used to activate PPARα. Autophagy inhibitors including 3-methyladenine (3-MA) and small interfering RNA against Atg7 ( Atg7 siRNA) were used to inhibit the autophagy.Western blot assay was performed to detect the expression of autophagy-related proteins ( Atg5, Atg7, Beclin-1 and LC3).The transcriptional levels of TNF-α, IL-1β, IL-6, Atg5, Atg7 and Beclin-1 were analyzed by qRT-PCR.Results Compared with the macrophages treated with LPS alone, those pretreated with various concentrations of Wy-14643 (10 μmol/L, 25 μmol/L and 50 μmol/L) showed inhibited ex-pression of proinflammatory cytokines ( TNF-α,IL-1βand IL-6) and enhanced expression of autophagy-relat-ed proteins (Atg5, Atg7 and Beclin-1) at mRNA level in a dose-dependent manner.The expression of auto-phagy-related proteins (Atg5, Atg7, Beclin-1 and LC3) by macrophages was promoted with the pretreatment of Wy-14643 as indicated by Western blot assay.The transcriptional levels of TNF-α, IL-1βand IL-6 were increased in Wy-14643 pretreated-macrophages after stimulation with 3-MA or Atg7 siRNA .Conclusion PPARαsuppressed the macrophage-mediated inflammatory responses by promoting autophagy, suggesting that the PPARα-autophagy pathway might be one of the signaling pathways regulating LPS induced-inflamma-tory responses.
