Comprehensive cellular responses was found in human amnion fl cells following exposure to low concentration of mnng, such as the lowering of dna replication fidelity resulted from alteration of dna polymerase profile ; activation of a lot of transcription factors, such as api, creb, nf - kb etc ; clustering of egfr ( epidermal growth factor receptor ) and tnfr ( tumor necrosis factor receptor ) and activation of camp - pka - creb and jnk / sapk signal pathways
我們發現，低劑量mnng處理后的人羊膜fl細胞有廣泛的細胞反應，並有多個信號轉導通路的激活和基因表達的改變。例如dna復制保真度下降， dna聚合酶譜發生改變，應用報告基因技術和底物磷酸化檢出技術證明細胞一系列轉錄因子如ap1 、 creb 、 nf b等被激活，細胞表面受體如表皮生長因子受體、腫瘤壞死因子受體發生聚簇，細胞信號轉導通路camp - pka - creb和jnk sapk被激活。 -
Based on a 3. 1kb pst i fragment of genomic dna of a wild s. avermitilis, a 1. 5 kb apramycin resistance fragment was inserted into sph i site of avec gene in the 3. 1 kb fragment, then a recombinant plasmid pc05 was obtained by introducing above inactivated avec fragment into mcs region of phjl401. competent cells of et12567 were transformed by recombinant plasmid pid03 and pc05 respectively
以含有avec基因的3 . 1kb基因組dnapsti片段為基礎，將1 . 5kb的安普黴素抗性基因片段插入到avec基因中的sphi酶切位點，再將此插入失活的avec基因片段連接到具有接合轉移功能（含有orit基因）的鏈黴菌-大腸桿菌穿梭質粒phjl401的多克隆位點區，由此得到重組質粒pc05 。 -
The cells were then stimulated with various concentrations and incubation times of oligochitosan to study dose - dependent and time - dependent manners. the effect of oligochitosan on the production of no released by raw264. 7 cells was evaluated by griess method, which was also used to evaluate the effect of nf - kb inhibitor on no production induced by oligochitosan. western blot was performed to detect the protein content of nf - k b in the nuclear extract
本課題以小鼠單核/巨噬}炎魏細胞raw264 . 7為研究對象，觀察殼寡糖單獨作用於巨噬細胞對其產生no的影響，並初步探討了核轉錄因子一kappab （ nf一kb ）在這過程中的作用，旨在部分解釋殼寡糖對免疫系統調節作用的機理，為其在醫學上的應用提供理論依據。 -
The protein level of nf - kb in nucleus peaks at 6 h after stimulation and persists for at least 6 h. pdtc ( pyrrolidinedithiocarbamate ), an inhibitor of nf - kb, the effective concentration of it for nf - kb inhibition without any toxicity on cells is up to 100 umol / l, can significantly block no production induced by oligochitosan. although the study reported herein reveals that oligochitosan induces no production via nf - kb in macrophage, which is an important signaling mechanism of oligochitosan inducing immuno - enhancement of macrophage in vitro
加入100林mol / l劑量的nf一忍抑制劑毗咯烷二硫代氨基甲酸鹽（ pnte ）作用於rawz 「 . 7細胞（ 4火10 ，個細胞/ ml ） 90rnin ，然後再加入100林留而劑量的殼寡糖對巨噬細胞進行刺激，發現pdtc在各個時間點（ 6 、 12 、 18 、 24h ）都明顯抑制殼寡糖對巨噬細胞no的誘導作用。 -
Nuclear factor - kb ( nf - kb ) is one kind of cell transcription factor that exist in many kinds of cells in nervous system. it is also has great association with the process of neuronal degeneration and apoptosis. from the above we can see that tbi, secondary brain injury, apoptosis and cytokines associated tightly
細胞核因子b （ nuclearfactor - b ， nf - b ）是一類普遍存在的細胞轉錄因子，功能性nf - b復合物存在於神經系統的各種類型的細胞中，包括神經元、星形膠質細胞、小膠質細胞、少突膠質細胞中，在神經細胞變性和凋亡過程中起十分重要的作用。 -
The successfully constructed artificial chromosome would also can be used as a new vector to introduce chromosome segments of hundreds kb to mb length into plant cells
成功構建的植物人工染色體也可以作為一種新型的載體用來克隆和轉化長達幾百kb到一個mb的外源dna進入植物細胞。 -
Ganoderma sp. 24, ganoderma australe ( fr. ) pat. 60 and ganoderma sanmingense zhao et zhang 63 show high activities of inhibiting kb or hl - 60 cells, and ganoderma sp. 24 and ganoderma sanmingense zhao et zhang 63 have a - glucosidase inhibitory activities in vitro
樹舌24和南方樹舌60的氯仿相對kb細胞和hl - 60細胞摘要都有抑制活性：而三明樹舌63 「的乙酸乙酯相對b細胞有一定的抑制活性。
