beta region 中文意思是什麼
beta region
解釋
相區域-
The differences of biodiversity indices and vegetation coverage between the designed vegetation restoration pattern and the field data indicated that alpha and beta diversity indices were decreased in some parts of the region after vegetation restoration, however, vegetation coverage was reasonably increased, which would enhance the capability of soil and water preservation, thus could improve the ecological security of the region
通過對比分析現狀植被蓋度及生物多樣性與植被恢復格局預測結果的差異，對區域植被恢復的效果進行評價，認為盡管植被恢復格局設計使部分區域生物多樣性下降，但它整體提高了地表植被覆蓋度，增強了抵禦土壤侵蝕的能力，對保障區域生態安全具有積極的效果。 -
In order to further investigate the role of axudl in human tumor carcinogenesis and the potential association between the axudl gene expression status and the stimulation of transforming growth factor beta in human cancers, the present study was performed in three aspects as follows : ( 1 ) cloning full length enconding region cdna of axudl and construction of eukaryotic vector that expression the fusion protein of axud1 and influenza virus hemagglutin ha epitope tag ; ( 2 ) exploring the time and dose effects of tgf - 1 on the expression - of axudl gene in hepg2 hepatoma cells and spc - a1 lung carcinomas cells, and studying the effects of overexpression of axud1 on the expression of cell cycle and apoptosis related protein in hepg2 hepatoma cells ; ( 3 ) construction and expression of human axudl in e. coli m15. the following main results and conclusions can be obtained from the present study : 1. the full length ecnoding region of human axudl cdna from human peripheral blood lymphocytes was successfully cloned using one step rt - pcr method, and constructed into a eukaryotic expression vector which can be expressed a ha - axud1 fusion protein with axud1 and influenza virus hemagglutin ha epitope tag. the recombinant plasmid was identified by polymerase chain reaction, restriction endonuclease maping and sequencing, this expression vector might be instrumental to further study the function of axud1 protein in tumor cells
為了進一步研究axud1在人類腫瘤發生中的作用及axud1基因的表達狀況與tgf -介導的信號通路的關系，本實驗研究分為三個部分： （ 1 ） axud1基因cdna全長編碼區的克隆和ha表位標記的axud1基因表達載體的構建； （ 2 ）探討肝癌細胞hepg2和肺腺癌spc - a1細胞中tgf - 1誘導的axud1基因表達的時間、劑量效應以及誘導表達的可能機理，並研究axud1的過表達對細胞周期和細胞凋亡相關蛋白表達的影響； （ 3 ） axud1原核表達載體的構建及其在大腸桿菌中的表達。本實驗的主要結果和結論如下： 1利用一步法rt - pcr成功地從人類外周血淋巴細胞中克隆出axud1基因編碼區cdna ，並將其構建入真核表達載體中，編碼的ha - axud1融合蛋白帶有流感病毒凝血素ha的表位標記肽段。 -
In order to get some functional clues from their structures, the upstream regulation region of ndrgl gene and second structure of ndrg2 protein are performed bioinformatics analysis ; we found that there are several binding sequences of some diffirent transcription factors, their functions include regulating tissue - specific gene expression, regulating expression of genes related to growth and early development of cells, besides this, regulating expression of genes under some stimulated conditions, and so on. predict in protein fold classification shows that ndrg2 belongs to alpha / beta hydrolase fold family, and there are high similarity between ndrg2 and epoxide hydrolase from bacteria, this suggests that ndrg2 protein may has enzymatic functions associated with resisting the oxidative stress, maintaining the balance of cell redox potential, involving in the metabolism process of xenobiotics or intracellular toxic molecules
研究發現呷基因的調控區存在多種轉錄因子結合位點，功能主要涉及組織特異性表達調控，細胞生長發育相關基因的表達調控，刺激反應基因的表達調控等； ndrgz蛋白在結構上屬于a小水解酶類折疊，折疊分類預測表明ndrg2與其中的的細菌環氧化物水解酶的二級結構極為相似，提示ndrgz蛋白具有一定酶活性，可能參與細胞抗氧化應激反應，維持細， an ） armtbffiofbfochmilsyn ） mdafblechmrbfobo4第四軍醫大學碩士學位論文胞內氧還電勢平衡，參與內外源有毒物質的代謝等。 -
