[ Method] Experiments were divided into 4 groups: group Ⅰ (blank control group) ; group Ⅱ (liposome group) ; group Ⅲ (SCON group: 20 μmol/L sense oligonucleotide) ; group Ⅳ (ASCON: 20 μmol/L antisense oligonucleotide). VEGF and its receptor Fit-1 mRNA expression changes were detected by using real-time fluorescence quantitative detection after 24, 36 and 48 h. [ Result] The expression of VEGF mRNA in group Ⅰ, group Ⅱ were insignificantly different at higher expression levels, and did not change significantly with the time; the expression of VEGF mRNA in group Ⅲ assumed a slight decrease, but there were no significant differences between group I and group Ⅱ (P 〉0.05), the expression of VEGF mRNA in group Ⅳ(antisense oligonucleotide group ) decreased significantly (P 〈 0.05) ; the expression of VEGF receptor FLT-1 mRNA was similar to that of VEGF. [ Conclusion] Antisense inhibition ghrelin has a downward effect to the expression of VEGF and its receptor Fit-1 the mRNA.展开更多
