Decline at hour 6, 24 and day 3, the positive rates of Egr-1 mRNA were (8±2)%,(8±6)% and (8±4)% respectively. Reincrease at day 7, a peak at day 28, the positive rate of Egr-1 mRNA was (45±6)%(compared with other phase, P＜0.01). At day 42, the expression of Egr-1 mRNA declined again. Immunohistochemical staining and Western blot revealed Egr-1 protein had expressed at hour 2 early phase, the expression of Egr-1 protein was (30±5)%, and until to hour 6. The level of Egr-1 protein was decrease at hour 24 and day 3, the positive rates were (7±3)% and (7±8)% respectively.

Two relevant sites of enzymatic digestion were added to the mTNF-α by PCR. The mTNF-α was linked to the 3'end of m/〓 in pGEX4T-1 vector. The prokaryotic expression vector pGEX4T-1m/〓-mTNF-α was constructed successfully. After induction and expression by IPTG, the expression of two kinds of fusion protein is 15% and 12% of total bacteria proteins respectively. The anti-HCC bifunctional antibodies m/〓-mTNF-α were identified by electrophoresis after the inclusion bodies were purified, denature, renature, re-purified, digested by thrombin and further purified.

To test the hypothesis, neontal rat cadiomyocytes Treat with heat shock(HS,42℃,2h) to induce the expression of HSP70,then teated with 0.5mmol/L H2O2. We first found H2O2 can reduced cadiomyocytes apoptosis and HSP70 only over-expression in the HS group, other two group only express HSP70 a little in the test of expression of HSP70.Then we tested the concentration of Ca2+, the [Ca2+ ] of CON was 192.224+6.654, the [Ca2+ ] of H2O2 group was 290.6918+8.922and the [Ca2+]of HS group was 214.2633+4.484.To further determine how HSP70 repaired the Ca2+ homestasis, we measured calcium transient of each group.

This implies that DNA methylation of promoter exon 1_7 may not underly the mechanism of GR up-regulation in GLP-1 -programmed rats.5 Hippocampal expression of GLP-1R and NGFI-A mRNAHippocampal GLP-1R (p =.009) and NGFI-A (p =.001) gene mRNA expression were significantly up-regulated in GP group as compared to VP group.Taken together, neonatal intramuscular injection of plasmid DNA encoding GLP-1 affects behavior and hippocampal GR expression in adolescent rats.
