Viciae hurL gene formed nodules in wild-type amounts, indicating that hurL gene is required for nodulation. Although the function of hurL gene in inducing nodulation remains unknown, the results of this work revealed that in addition to the nod and exo genes located on Sym plasmid, the R. leguminosarum chromosomal hurL gene is also involved in controlling its capacity in inducing nodulation on host plant.
虽然目前对hurL基因影响豌豆根瘤菌诱导植物结瘤能力的机制并不清楚,但本文的研究结果首次证明:除位于共生质粒上的结瘤基因和胞外多糖基因外,豌豆根瘤菌在宿主植物上的结瘤还受到染色体基因hurL的控制。

P210bcr/abl plays a central role in the pathophysiology of CML. The purpose of this study was to construct a cell line model that bcr/abl expression can be regulated by Tetoff inducingexpressionsystem. The fulllength b3a2 bcr/abl cDNA was subcloned into the pTRE2hyg expression vector to construct the pT2P210 plasmid.
CML是目前致病分子信号基础研究最为清楚的肿瘤之一,1960年Nowell和Hungerford在CML患者的白血病细胞中发现Ph染色体[1],1973年Rowley等[2]进一步应用染色体分带技术证明,Ph染色体是由9q34的abl基因和22q11 的 bcr 基因相互易位形成的 bcr/abl 融合基因。

In order to study the expression, subcellular distribution and the function of NS2 protein, the coding region of NS2 was amplified from the hindgut tissue of cockroaches infected with PfDNV by RT-PCR and then the recombinant prokaryotic expression vector pET28a-NS2 was constructed. The recombinant plasmid was transformed into E. coli BL21 (DE3) to express the 6×His fusion protein in the bacteria.
为了对该基因进行深入的功能研究,从感染了黑胸大蠊浓核病毒的蟑螂的后肠组织中通过RT-PCR得到ns2基因编码序列,将其构建于原核表达载体pET-28a,转化大肠杆菌BL21(DE3)获得融合表达产物。

The results of transient transfection showed that the recombinant plasmid could be lowly expressed in the murine macrophage cell line RAW264.7 and murine melanoma cell line B16, both of which can endogenously express Tim-3, but not in the African green monkey kidney cell line COS-7 in which no endogenous Tim-3 could be detected.
结果 pGL3-Tim-3P2经PCR、双酶切及DNA测序分析鉴定正确无误;pGL3-Tim-3P2转染RAW264.7和B16细胞(两种细胞均可表达内源性Tim-3)24 h和48h,双荧光素酶活性检测显示其启动子相对活性约为pGL3-Basic空载体的2倍;而pGL3-Tim-3P2转染不表达内源性Tim-3的COS-7细胞后检测不到荧光素酶活性。
