OBJECTIVETo observe the effects of conditioned medium from keloid fibroblasts under hypoxia on angiogenesis, and to investigate the role of hypoxic microenvironment in invasive growth of keloid.
METHODSPrimary keloid fibroblasts and human umbilical endothelial cells (HUVEC) were cultured as conventional method. Keloid fibroblasts were cultured either in a hypoxic incubator (2% O2) for 48 h or in a normoxic incubator (20% O2) as control. Then those cell culture mediums were collected and mixed with endothelial cell medium by the proportion of 1:1 as conditioned medium. The mRNA and secreted protein of pro-angiogenic factors such as vascular endothelial growth factor (VEGF), angiopoietin-1 (Ang-1) and periostin of keloid fibroblasts under hypoxia were detected by real time PCR and ELISA. The proliferation, migration and invasion, tube formation of HUVEC cultured with conditioned medium were evaluated by CCK-8 assay, Transwell assay and matrigel tube formation assay, respectively.
RESULTSHypoxia increased the expression of VEGF, Ang-1 and periostin in both mRNA (increased by 75%, 43% and 118% respectively, P < 0.05) and secreted protein (increased by 30.2%, 14.2% and 19.5% respectively, P < 0.05) levels; the proliferations of HUVEC in hypoxic conditioned medium in 1, 2 and 3 d were 0.67 +/- 0.07, 0.84 +/- 0.09 and 1.08 +/- 0.10 respectively, which were higher compared to those in control group (0.52 +/- 0.08, 0.72 +/- 0.10 and 0.91 + 0.14, P < 0.05); the numbers of migration, invasion and tube formation of HUVEC were (73.2 +/- 8.9), (56.3 +/- 12.5), (9.66 +/- 1.96) cells/HP, which were higher compared to those in control group [(59.0 +/- 8.0), 35.5 +/- 8.5), (6.5 +/- 1.87) cells/HP, P < 0.05].
CONCLUSIONSHypoxia increases the expression of pro-angiogenic factors of keloid fibroblasts, and its conditioned medium under hypoxia could promote angiogenesis. The results suggest hypoxic microenvironment may play a significant role in the invasive growth of keloid by inducing angiogenesis.

Objective To investigate the pathogen-related genes of atmospheric polluting disease so as to clarify the biology mechanism and provide the scientific basis.Methods By using the technique of dot blot hybridization,we analyzed genes’differential expression with cloning by exposure to ≥75 μg/m3 PM2.5 in heating season and < 75 μg/m3 PM2.5 in un-heating season in WI-38 human embryo lung cells.The levels of cytokines TNF-α,IL-2, IL-6 and IL-8 were determined by radio immunity assay. Results After 24h of treatment, compared with control group,more than 100μg/mL PM2.5 significantly increased TNF-α,IL-6 and IL-8 levels,and decreased IL-2 in WI-38 human embryo lung cells (P < 0.05 ).The clear stripe was found in 350 bp in 48 gene samples with segment with differential expression of genes exposed to different concentrations of PM2.5 in WI-38 human embryo lung cells.Through the dot blot hybridization,black brown spots were found in 41 samples in Tester cDNA hybridization,and no similar spots were found in all of the same samples in Driver cDNA hybridization. Conclusion PM2.5 exposure may induce the inflammatory damage of WI-38 human embryo lung cells.Obvious genetic damage was observed in those cells exposed to ≥75 μg/m3 PM2.5 in heating season.

Objective To observe the protective effects of Toll-like receptor(TLR)-4 siRNA against acute liver injury in mice induced by lipopolysaccharide(LPS)and D-galactosamine(D-GalN).Methods One hundred and fifty C57BL/6 male mice were divided into 5 groups: phosphate buffered solution(PBS)pretreatment group,negative control plasmid pretreatment group,TS4 pretreatment group,TS6 pretreatment group and TS7 pretreatment group.Acute liver injury was induced in mice by intraperitoneal coinjection of LPS(10 ng/g)and D-GalN(1 mg/g).In vivo delivery of siRNA was performed via the tail vein by hydrodynamic injections(50 μg siRNA dissolved in 1 mL PBS)24 h and 48 h before coinjection of LPS and D-GalN. Expression of TLR-4 in liver tissues was measured by immunohistochemistry.The changes of TLR-4,tumor necrosis factor(TNF)-α and macrophage nflammatory protein(MIP)-2 mRNA levels in liver tissues were determined by reverse transcriptasepolymerase chain reaction(RT-PCR)analysis.MIP-2 and TNF-α concentrations in the sera of mice were determined by enzyme-linked immunosorbent assay(ELISA). Levels of alanine transaminase (ALT) and aspartate transaminase(AST) in serum were measured by standard autoanalyzer techniques. Liver pathological changes were observed by haematoxylin-eosin staining, while cell apoptosis levels in liver were determined by terminal deoxynucleotidyl-mediated-dUTP nick end labeling (TUNEL)assay. The difference of survival rates in 5 groups was analyzed by Fisher's exact probability test.ResultsPretreatment with TLR-4 siRNA down-regulated the TLR-4 mRNA and protein expressions,and significantly decreased the mortality and liver injury caused by coinjection of LPS and D-GalN in C57BL/6 mice.TLR-4 siRNA significantly down-regulated the TNF-α and MIP-2 mRNA expression and cytokine levels as determined by RT-PCR and ELISA,respectively. TLR-4 siRNA abrogated hepatocyte necrosis and inflammatory infiltration and also remarkably reduced serum concentrations of transaminases. The percentage of TUNEL-positive hepatocytes was significantly reduced in TLR-4 siRNA pretreatment group(TS4 pretreatment group: 0.065±0.015 vs PBS pretreatment group; 0.346±0.062,P<0.05).ConclusionIt suggest that inhibition of TLR-4 expression by TLR-4 siRNA may provide potential application value for preventing liver injury.
