The effects of drug treatment, gene transfection, and p5. RNA interference (RNAi) on level of ING1 mRNA in tumor cells were quantitatively detected with the help of ING1 molecular beacon (MB)/cRNA standard curve based on MB detection technology. Results showed that the level of ING1 mRNA could be upregulated by 5.FU treatment or ING1 transfection in low expression cell line of MCF-7 and be inhibited by silencing p5. with RNAi technology in normal expression cell line of CNE2. The level of ING1 varied from 7.7×10?16 to 5..4× 10?16 mol/μg total RNA of tumor cells. The results not only provided evidence for the regulation effects of gene expression but also were applied to investigat- ing the interaction of multigenes on signal transduc- tion pathway.

To validate the immune protective efficacy of pORF5.DNA vaccine and to analyze potential mechanisms related to this protection. In this study, pORF5.DNA vaccine was constructed and evaluated for its protective immunity in a mouse model of genital chlamydial infection. Groups of BALB/c mice were immunized intranasally with pORF5.DNA vaccine. Humoral and cell mediated immune responses were evaluated. The clearance ability of chlamydial challenge from the genital tract and the chlamy- dia-induced upper genital tract gross pathology and histopathological characterization were also de- tected. The results showed that the total and the IgG2a anti-pORF5.antibody levels in serum were sig- nificantly elevated after pcDNA3.1-pORF5.vaccination, as were the total antibody and IgA levels in vaginal fluids. pcDNA3.1-pORF5.induced a significantly high level of Th1 response as measured by robust gamma interferon (IFN-γ). Minimal IL-4 was produced by immune T cells in response to the re-stimulation with pORF5.protein or the inactive elementary body in vitro. pcDNA3.1-pORF5.vacci- nated mice displayed significantly reduced bacterial shedding upon a chlamydial challenge and an accelerated resolution of infection. 100% of pcDNA3.1-pORF5.vaccinated mice successfully resolved the infection by day 24. pcDNA3.1-pORF5.immunized mice also exhibited protection against patho- logical consequences of chlamydial infection. The stimulated index was significantly higher than that of mice immunized with pcDNA3.1 and PBS (P5.. Together, these results demonstrated that immu- nization with pORF5.DNA vaccine is a promising approach for eliciting a protective immunity against a genital chlamydial challenge.

AIM:To determine whether the use of an antioxidant re- agent coenzyme Q10 can protect human dopaminergic cell line SHSY-5. against rotenone-induced apoptosis. METHODS:Cell viability was quantified by 3-(4,5.dim- ethyhhiazol-2-yl)-2,5.diphenyhetrazolium bromide(MTF) assay and the apoptosis induced by rotenone was observed by Hoechst 33342,propidium iodide,and ealcein AM staining in SHSY-5. cells. RESULTS:Rotenone,a commonly used natural pesti- cide,inhibitor of mitochondrial respiratory chain complex I,was shown to decrease cell viability and induce apopto- sis in SHSY-5. *** with coenzyme Q10,the electron transporter in the mitochondrial respiratory chain, remarkably increased cell viability as well as significantly reduced the percentage of apoptotic SHSY5. cells induced by rotenone. CONCLUSION:Coenzyme QI0 has a beneficial effect in protecting against rotenone-indueed apoptosis in SHSY-SY *** results support the hypothesis that coenzyme QI0 is a component of the antioxidant machinery that pro- tects cell membranes from oxidative damage and decreases *** evaluation is required to determine whether the neuroprotective action of coenzyme Q10 can be used for the prevention and therapy of neurodegenerative diseases.

To solve the problem of immune incompatibility, nuclear transplantation has been envisaged as a means to produce cells or tissues for human autologous transplantation. Here we have derived embryonic stem cells by the transfer of human somatic nuclei into rabbit oocytes. The number of blastocysts that developed from the fused nuclear transfer was comparable among nuclear donors at ages of 5. 42, 5. and 60 years, and nuclear transfer (NT) embryonic stem cells (ntES cells) were subsequently derived from each of the four age groups. These results suggest that human somatic nuclei can form ntES cells independent of the age of the donor. The derived ntES cells are human based on karyotype, isogenicity, in situ hybridization, PCR and immunocytochemistry with probes that distinguish between the various species. The ntES cells maintain the capability of sustained growth in an undifferentiated state, and form embryoid bodies, which, on further induction, give rise to cell types such as neuron and muscle, as well

注意捕获研究对于探讨两种控制过程:自上而下的加工与自下而上的加工之间的关系具有重要的意义。本文通过检验不同工作记忆负荷对注意捕获的影响,探讨自上而下的认知控制对注意捕获的影响机制。本研究共包括二个实验:实验一比较了单、双任务条件对颜色干扰子注意捕获的影响;实验二探讨了不同工作记忆负荷对颜色干扰子注意捕获的影响。实验结果表明:工作记忆不仅在选择性注意任务中具有认知控制作用,而且这种作用能扩展到注意捕获现象中。注意捕获不是纯粹的刺激驱动的加工过程,它还受到自上而下的认知控制的调节。具体表现为,随着工作记忆负荷水平的增加,无关干扰子产生的注意捕获的程度增大。
