telomerase rna 中文意思是什麼

telomerase rna 解釋
端粒酶rna
  • telomerase : 端粒（末端轉移）酶
  • rna : RNA ＝ribonucleic acid 【生物化學】核糖核酸。
  1. Introduction telomerase is a ribonucleoprotein reverse transcriptase that synthesizes telo - meric dna sequences using its rna as template. it can remedy the loss of te - lomere after cellular mitosis, maintain telomere length and stabilize chromosome

    前言端粒酶（ telomerase ）是一種核糖核蛋白逆轉錄酶，能以自身的rna為模板，從頭合成染色體末端的端粒dna ，彌補細胞分裂時端粒dna的丟失，維持端粒的長度並穩定染色體。
  2. Telomerase is a ribonucleoprotein complex ( rnp ) composed by its rna component and protein subunits. telomerase can synthesize telomeric dna onto chromosomal ends using its own rna component as a template, elongate the length of telomere, increase cell life and even induce cell immortalization

    端粒酶（ telomerase ）是由端粒酶rna和蛋白質組成的一種核糖核蛋白復合物（ rnp ） 。端粒酶含有引物特異識別位點，能以自身rna為模板，逆轉錄合成端粒dna並加到染色體末端，使端粒延長，從而延長細胞的壽命甚至使其永生化。
  3. Telomerase, a eukaryotic ribonucleoprotein complex, contains both essential rna and a protein reverse transcriptase subunit

    端粒酶是一個特殊的具有反轉錄活性的核糖核蛋白。
  4. Relation of telomerase rna, hpcaga and expression of pcna in gastric mucosa

    及增殖細胞核抗原表達的關系
  5. This thesis mainly focuses on : ( 1 ) effects of the expression of telomerase antisense rna gene on the morphology and biochemical characters of human liver cancer smmc - 7721 cells

    本研究根據端粒酶的結構和功能以及端粒酶的反應特點，從以下幾方面進行了研究。
  6. We concluded that excessive expression of exogenous htr gene may compete with the endogenous telomerase rna and prevent rna template from combining with telomeric dna, thus repressing the elongation of telomeric dna ( telomeres ) and causing cell aging and cell death. - 6 - 3. some modifications have been made to overcome the limitation of conventional telomeric repeat amplification protocol ( trap ) assay

    分析其原因，可能是htr基因的過表達在數量和空間效應上同細胞內的端粒酶rna組分產生竟爭，一定程度上阻礙了端粒酶rna模板區與端粒dna的結合，從而抑制端粒dna的延伸，導致細胞凋亡。
  7. ( 2 ) effects of the expression of telomerase rna gene on the telomerase activity in human normal peripheral blood leukocytes, cell growth and cell proliferation

    利用基因工程技術從hela細胞中克隆了人端粒酶rna組分（ htr ）基因。
  8. Hur k, gazdar af, rathi a, et al. overexpression of human telomerase rna in helicobacter pylori - infected human gastric mucosa [ j ]. cancer res, 2000, 91 ( 11 ) : 1148

    司君利，劉吉勇，元玉琴.幽門螺桿菌感染與胃粘膜端粒酶活性關系的研究[ j ] .世界華人消化雜志， 1999 ， 7 （ 5 ） : 429
  9. ( 3 ) establishing a new method which can quantitatively determinate telomerase activity. 1. human telomerase rna component ( htr ) gene was cloned from hela cells using gene engineering technology. the htr gene was then reverse inverted into retrovirus vector plncx and constructed an antisense recombinant plasmid plncx - atr

    將htr基因插入逆轉錄病毒載體plncx中，構建了htr基因的反義重組質粒plncx - atr和正義重組質粒plncx - tr ，測序結果表明符合預期要求，為下一步實驗奠定了基礎。
  10. To investigate the silence effect of hela cells " telomerase gene expression after shrna based on human telomerase htert transfected into cells. methods : we constructed a partial double - strand dna with t7 promoter as dna template and synthesized small hairpinrna in - vitro using t7 rna polymerase

    方法：根據端粒酶htert基因1573 ? 1591位的核酸序列，構建帶t7啟動子的部分雙鏈dna模板，用t7rna聚合酶體外合成短鏈shrna 。
