小熊猫源犬瘟热病毒DNA疫苗构建及其在真核细胞的表达

open access: yes野生动物学报, 2015
根据Gen Bank中发表的犬瘟热病毒(CDV)的基因组序列设计了H和F基因的2对引物,通过RT-PCR扩增出从发病小熊猫分离的CDV的H和F基因,并将其克隆入到18T-simple载体上进行测序。使用Kpn I和Xho I限制性内切酶对重组载体进行双酶切并将目的基因克隆到pcDNA 3.1表达载体上,构建完成后转染293T细胞,转染48 h后,再利用RT-PCR和Western-blot检测目的基因的转录和目的蛋白的表达。结果表明,表达载体经转染后,在293T细胞中,目的基因均能得到转录而且正确表达 ...

Studies on Heat Tolerance in Abalone Based on the Measurement of Heart Rate [PDF]

open access: yes, 2016
鲍是海产八珍之首,2015年,我国的鲍产量已经超过13万吨,其中福建省的产量占全国的80%。皱纹盘鲍为温带种,原分布于我国黄、勃海海域,1990年代后期南移福建后,获得了极大发展,由此福建逐步成为我国鲍养殖的主产区。但福建海域的夏季高水温往往导致鲍的高死亡率,这一直困扰着鲍养殖产业的发展。因此,培育耐高温的养殖新品种显得格外重要,而其中建立鲍的耐高温性状的准确测评方法是品种培育的关键。本研究中,我们通过测定阿氏拐点温度(Arrheniusbreakpointtemperature,ABT ...

鉴定AP-4是在非激素依赖型前列腺癌中上调L-plastin表达的转录因子

open access: yesZhongshan Daxue xuebao. Yixue kexue ban, 2006
【目的】鉴定AP-4是在非激素依赖型前列腺癌中调控L-plastin表达的转录因子,进一步阐明非激素依赖型前列腺癌的发病机制。【方法】在鉴定L-plastin启动子近3’端-216到1序列片段存在明显的转录活性的基础上,利用TFSEARCH软件分析该片段的序列,寻找可能调控L-plastin表达的非甾体激素类转录因子,并用凝胶滞后实验和超滞后实验证实结合于该片段的转录因子,利用PCR定点突变法构建删除该转录因子结合位点的重组子,并检测切除该片段序列后荧光素酶活性 ...

Transcriptomic study of a toxin-producing dinoflagellate Alexandrium catenella [PDF]

open access: yes, 2015
亚历山大藻(Alexandriumspp.)是一种能够产生麻痹性贝类毒素(paralyticshellfishtoxins,PSTs)的海洋甲藻,广泛分布于近海环境中。近年来由其产生的毒素导致的海洋生物死亡及人类中毒事件频发,严重威胁到近海生态系统、水产养殖业、人类健康和生命财产安全,已成为一个全球性的环境和健康问题。虽然目前在亚历山大藻毒素来源及产毒生理方面取得了较大进展,但对毒素合成机制的了解仍较少。 本论文以有毒链状亚历山大藻(Alexandriumcatenella)为研究对象 ...

循环长链非编码RNA在人类非肿瘤性疾病中的研究进展

open access: yesZhongguo shiyan zhenduanxue, 2017
随着高通量测序、基因芯片等技术的兴起以及生物信息学的应用,大量的基因组转录本被揭示,从此众多的研究成果不断涌现,为揭示基因中的奥秘提供了新思路。研究发现[1],人类93%的基因组DNA可转录成RNA,编码蛋白的基因仅仅为人类基因组的2%[2],而其余98%则为不具有或具有极低蛋白质编码功能的非编码RNA(non-coding RNA,ncRNA)。成百上千个非编码RNAs被转录,并且被认为是具有不同大小、结构和生物功能的功能性RNA ...
