Methods: On the basis of cloning the M-TNF c D NA encoding region,the authors constructed mTNFm,which could potentially expre ss on the c ell surface with a uncleavable type of TNF resulting in deletion of the sequence encoding enzymatic cleavage site of TNF-α-converting enzyme.

在克隆M-TNF cDNA的基础上，删除两型TNF转换酶酶解部位的编码序列，构建出mTNFm并测序验证；建立只表达膜型T N F的真核细胞株。

From the present study, it has been demonstrated that CD44 is cleaved subsequently by MT1-MMP and Presenilins in PC-3 Cells, and in turn causes the release of the CD44ICD. CD44ICD translocates into nuclear and may regulate the tumor cells malignant phenotype via NF-κB pathway which plays a critical role in the malignant progression of prostate cancer, interruption of this pathway might contribute to the inhibition of tumor growth and invasion.

本研究表明：在PC-3细胞中CD44分子分别受MT1-MMP和Presenilin1/2的作用，最终导致CD44ICD从膜结合型CD44ΔE的水解释放并转移进核，并可能通过调控NF-κB等转录因子，影响肿瘤细胞的恶性表型。

Chiral SalanCrX complexesa saturated version of SalenCr(ⅢX are designed,and in conjunction with an ionic quaternary ammonium salt or organic strong base can efficiently catalyze the asymmetric,regio-and stereoselective alternating copolymerization of CO_2 with rac-PO at mild conditions to afford isotactic-enriched polycarbonates with～95%head-to-tail linkages and moderate enantioselectivity.

Cinnamomea, antrocamphin A was purified from previous ethanol extraction using bioactivity-guided fractionation. As results, the antrocamphin A could significantly inhibit NO and PGE2 autacoids production in LPS-induced RAW 264.7 macrophage cells. Meanwhile, the mRNA and protein expression levels of iNOS and COX-2 were inhibited by antrocamphin A in a dose-dependent manner. Antrocamphin A also reduced the translocation of NF-κB induced by LPS, which was associated with the prevention of the degradation of I-κB, and subsequently decreased p65/p50 proteins level in the nucleus. This is the first report demostrating the A.
