ABSTRACT
Objective To investigate the relationship of-174G ＞ C polymorphism of interleukin 6 (IL-6) gene promoter region upstream-with coronary heart disease (CHD) of Chinese Han population in Nanjing area.Methods The polymorphism of IL-6-174G ＞C gene was confirmed in 235 patients with CHD and 175 healthy individuals by PCR-RFLP,and Hardy-Weinberg equilibrium was tested.DNA samples were selected for sequencing to verify their genotype.The concentration of blood sugar,lipid,C reaction protein (CRP) and glycosylated hemoglobin (HbAlc) in the samples were measured simultaneously.Results The genotype distributions of GG,GC and CC were 98.7％,1.3％ and 0 in CHD group and 97.7％,2.3％ and 0 in control group,respectively.The frequencies of G and C alleles were 99.4％,0.6％ and 98.9％,1.1％ in the two groups.There were no statistical significance for frequencies of genotype and alleles between the two groups (all P ＞ 0.05).Compared with the control group,the differences of smoking,systolic blood pressure (SBP),diastohc blood pressure (DBP),triglyceride (TG),cholesterol (CHOL),low-density lipoproteins-cholesterol (LDL-C),high-density lipoproteins-cholesterol (HDL-C),apolipoprotein A-I (ApoA-I),ApoB,CRP and HbA1 c were statistically significant (all P ＜ 0.05),while age,sex and blood glucose were not statistically significant (all P ＞ 0.05).Conclusion IL-6-174 G ＞ C gene polymorphism should not remarkably correlated with CHD in Chinese Han population in Nanjing area.
ABSTRACT
OBJECTIVE: To investigate the expression pattern of hoxd3 gene during early embryogenesis and angiogenesis of wild-type zebrafish. METHODS: Total RNA was extracted from embryos of zebrafish in different development stages by trizol. The cDNA of hoxd3 gene was amplified by RT-PCR. The RT-PCR product was ligated to pCS(2+) vector by T4 DNA ligatase polymerase and sequenced. T3 RNA polymerase in vitro transcription system was used to obtain the probe of digoxin-labeled anti-sense mRNA of hoxd3 gene. The expression pattern of hoxd3 was detected by whole embryo in situ hybridization (WISH) with anti-sense mRNA probe. RESULTS: pCS(2+)-hoxd3 plasmid was successfully constructed, which was used to prepare anti-sense mRNA probe of hoxd3 in vitro. Expression pattern of hoxd3 gene was detected by WISH during zebrafish early embryogenesis and angiogenesis. It was observed that hoxd3 mRNA was expressed at the junction region of midbrain and hindbrain in wild-type zebrafish in embryos at 24 â72h postfertilization(hpf). CONCLUSION: hoxd3 gene is mainly expressed in nervous system of wide-type zebrafish embryos.
