ricinism-
It is estimated that the protein, ricin, found in the castor bean plant is as much as 6, 000 times more poisonous than cyanide
據估計,蓖麻子豆中找到的一種名為蓖麻毒素的蛋白質,所含的毒性物質比氰化物多出了6000倍。Our goal is to express the ricin a chain ( rta ) and its modification rta - kdel ( er - retrival signal ) in escherichia coli
本論文旨在研究蓖麻毒素a鏈蛋白( rta )及其修飾體rta - kdel (內質網保留信號肽)在大腸桿菌中的表達。Ricin toxin ( rt ) is a plant toxin isolated from the seeds of ricinus communis. it is one of the most powerful plant toxin discovered
蓖麻毒素( ricintoxin , rt )是從大戟科植物蓖麻( ricinuscommnnis )的種子中提取的一種毒性蛋白,具有強烈的細胞毒性。We know from iraq ' s past admissions that it has successfully weaponized not only anthrax, but also other biological agents, including botulinum toxin, aflatoxin and ricin
我們從伊拉克過去承認的事實中了解到,它已不僅成功地將炭菌病毒制武器化了,而且將包括肉毒菌毒素、黃麴黴毒素和蓖麻毒素等生物制劑武器化了。A single molecule of rta is able to depurinate 1500 - 2000 ribosomes per minute. ricin b chain ( rtb ) is a galactose - specific lectin which binds to the receptors on cell surfaces, and may enhance rta translocation by forming a pore in the membrane of intracellular organelles. ricin enters the cells by receptor - mediated endocytosis
內吞進入細胞的蓖麻毒素一部分返回到膜表面,一部分經早期內體至晚期內體,最後在溶酶體中降解,只有一小部分約5到達高爾基體,隨后逆轉運到粗面內質網,在那裡rta才和rtb解離,游離出有催化活性的rta 。Because expressed in escherichia coli, ricin a chain is not degraded easily for its non - glycosylation. our experiments lay a foundation for the researches that rta conjugates a monoclonal antibody to synthesize immunotoxins and the immunotoxins are used for cancer - targeted therapy
蓖麻毒素a鏈在大腸桿菌中表達,因無糖基化修飾,克服了進入體內后被迅速降解的缺點,為進一步與單鏈抗體基因嵌合表達形成單鏈免疫毒素,對腫瘤細胞進行導向治療研究奠定基礎。分享友人
