中文拼音 [guǎhétánghésuān]
寡核糖核苷酸
英文
oligoribonucleotide-
Degenerate oligonucleotides to highly conserved regions of cucumis melo 1 - aminocyclopropane - 1 - carboxylic acid ( acc ) oxidase gene were used to prime the amplification of fragment of 128bp by ploymerase chain reaction ( pcr ) in samples of genomic dna from fruit of cucumis melo l. cv hetao flesh, which was cloned into plasmid vector pmd - 18 - t. the clon of antisense orientation were selected, and it was inserted downstream of camv35s promoter and enhancer " " of tmv into the plant expression vector pbinyxw, antisence expression vector pbinya was constructed. at the base that pollination and fertilization of cucumis melo l. cv hetao was studied, using pollen tube pathway transformate cucumis melo l. cv hetao, 76 fruit had been obtained, moreover, hardness and content of sugar were analysed
本實驗以河套蜜瓜果肉基因組dna為模板，用甜瓜acc氧化酶基因特異寡核苷酸鏈為引物進行pcr擴增，得到128bp的擴增產物。將得到的擴增產物克隆到質粒載體pmd - 18 - t上，篩選反向克隆，然後將其反向構建到植物表達載體pbinyxw的camv35s啟動子和tmv增強子「 」的下游，構建成反義表達載體pbinya 。並在對河套蜜瓜授粉受精生物學研究的基礎上，通過花粉管通道法轉化河套蜜瓜，共獲76顆瓜，並進行了硬度和含糖量的分析。To make clear the hypothesis, a middle cerebral artery occlusion ( mcao ) and hypoxia and glucose - deprivation ( hgd ) ischemic models were used in in vivo and in vitro study, respectively. we first studied the cellular localization of kvl. 2 and the co - localization of kvl. 2 protein and vegf receptors flk - 1 and flt - 1, observed the effect of mcao on kvl. 2 expression and phosphrylation in the rat brain in vivo, then investigated the effect of vegf on ischemia / hypoxia cell damage and tyrosine phosphorylation of kvl. 2 in sh - sy5y cells. finally, in order to further elucidate the relationship between vegf ' s neuroprotection and its regulation on kvl. 2 phosphorylation, we used a specific antisense oligodeoxynucleotide ( odn ) to knockdown the expression of endogenous vegf to observe its role in ischemia / hypoxia cell damage and regulation of kvl. 2 phosphorylation
為了驗證上述假設，本文分別在整體和離體水平，採用大腦中動脈缺血（ middlecerebralarteryocclusion ， mcao ）和體外氧?糖剝奪（ hypoxiaandglucose - deprivation ， hgd ）缺血模型，首先了解了kv1 . 2蛋白的細胞定位及與vegf受體flk - 1和flt - 1的共存情況，觀察了整體mcao后缺血再灌不同時間大鼠腦內kv1 . 2蛋白的磷酸化水平變化，然後通過外源性給予vegf蛋白，在sh - sy5y細胞株上觀察其對缺血細胞存活率及kv1 . 2蛋白磷酸化水平的影響，最後利用vegf反義脫氧寡核苷酸（ oligodeoxynucleotide ， odn ）特異阻斷內源性vegf蛋白的表達，觀察內源性vegf蛋白在缺血細胞損傷及調節kv1 . 2蛋白磷酸化中的作用，以進一步明確vegf缺血保護效應與其調節kv1 . 2蛋白磷酸化之間的關系。
