cell phenotype 中文意思是什麼

cell phenotype 解釋
細胞表現型
  • cell : n 1 小室，單室；隔間，艙；〈詩〉茅舍；（單個的）蜂窩，蜂房。2 〈詩〉墓穴，墓。3 （大修道院附屬的...
  • phenotype : n. 【生物學】1. 表現型，表型。2. 具有共同表型的一類有機物。
  1. Study on andrographolide with ril2 in promoting lak cell proliferation and phenotype change

    細胞生長及細胞表型變化的研究
  2. To get in vivo evidences that apoplast calmodulin con 1d regulate plant growth and development process, a chimeric secretion form of calmodulin binding peptide, which contains a signal peptide, a calmodulin binding domain and a c - myc epitope was constructed. the chimeric gene was introduced into arabidopsis. it was expected that the overexpression of this chimeric protein could be secreted into cell wall and bound to apoplast calmodulin, which could reduce the apoplast calmoduin concentration to make an apoplast camodulin " antisense " plant. by observing the potential phenotype change of apoplast calmodulin " antisense " plant, the in vivo function of apoplast calmodulin on plant growth and developmental process could be speculated

    但這些多是採用生理學手段和藥理學方法而得出的體外（ invitro ）實驗結果，為了取得質外體cam在植物生長發育過程中發揮重要作用的invivo實驗證據，根據動物中的一些研究方法，本實驗設計並構建了帶有信號肽、 cam結合肽（ can小肽） 、 epitope （ c - myc ）融合基因的載體，並將融合基因通過真空滲入法轉入擬南芥，預期過表達的融合蛋白將會被分泌到細胞外並與質外體cam相結合，這樣就會抑制質外體cam的功能，從而可以構建質外體cam的「反義」植株，通過觀察質外體cam 「反義植株」的表型改變，就可以推斷質外體cam在植物生長發育過程中的功能。
  3. Establishment of an immortalized chondrocyte cell line with chondrocyte phenotype derived from rabbit mandibular condyle

    具有軟骨細胞表型特徵的永生化兔髁突軟骨細胞系的建立
  4. At present, in an attempt to stimulate specific antitumor immunity, experimental models and clinical studies are currently evaluating the potent antigen - presenting capacity of dc combined with single or multiple tumor antigen epitopes. however, there are several problems in utilizing pulsing dc with synthetic immunodominant peptides from identified antigens. 1 ) the potential induction of tolerance ; 2 ) the need to determine the patient ' s hla haplotype, the limitation of therapy to patients whose tumors express defined specific tumor antigens in the context of the correct hla phenotype, the unavailability of peptides for all hla haplotypes ; 3 ) the lack of cd4 help cell - related epitopes for most antigens ; and 4 ) the ctl resulting from such protocols have a good in vitro capacity to kill peptide - pulsed target cells but only a modest capacity to kill tumor cells

    但是，學者們發現這一療法存在著如下的缺陷：單一ctl表位抗原肽的應用其抗腫瘤作用弱於多種腫瘤抗原的聯合應用，且有誘導免疫耐受的潛在危險，有時反而會促進腫瘤的生長；事先需對患者的hla單倍型進行鑒定，以確定ctl表位與hla單倍型是否匹配，目前尚缺乏能與所有hla單倍型相匹配的ctl表位，從而限制了這一療法的應用；這一療法所產生的ctl在體外能有效殺傷經腫瘤抗原肽共孵育過的靶細胞，但對腫瘤細胞的殺傷能力較弱：這種l表位抗原肽缺乏cd4汀h細胞相關的表位，因此，不能誘導有效的th細胞免疫應答。
  5. However, embryos conceived from brg1 - depleted eggs exhibited a zga phenotype including two - cell arrest and reduced transcription for approximately 30 % of expressed genes

    然而，由brg1蛋白缺失的卵細胞受精后形成的胚胎表現出zga表型變化，包括兩細胞期的發育停止以及近30 %表達基因的轉錄水平降低了。
  6. Rapl belongs to ras superfamily of small gtp - binding proteins, which is considered to control cell growth, differentiation and survival. rapl was regarded as an antagonist of ras because it can revert the phenotype of oncogene ras transformed cells. recent researches show that rapl has its ras - independent functions in a variety of cellular systems besides its effect as an antagonist of ras

    Rap1除具有逆轉原癌基因ras激活突變體所導致的細胞形態改變而被認為是ras的拮抗物外，最近的研究還發現rap1在一系列的細胞系統中有獨立於ras之外的功能，如控制與細胞粘附有關的事件等，因而成為研究的熱點。
  7. Only il - 1 could be used to predispose mesencephalic neural progenitors to enrich cell yield in a neuronal phenotype before cell transplantation. ( 2 ) the effects of cntf and il - 1 on neural progenitor differentiation were dose - related. ( 3 ) coeffects of elf - emf and cytokines were neither synergized nor antagonized, implying a potential role of organism emf during cns development

    顯示emf與cntf 、 il一1a的共同效應不是簡單的脅同或拮抗，提示emf可能與細胞因子共同影u向應著神經系統的發育。
