Proposal on strictly limiting use of carcinogenic or strong virose organic solvents as mobile phase in test of drugs
關于嚴格限制項目檢驗中使用致癌或強毒性有機溶劑作為展開劑的建議Studies of the crystal structure of endostatin have shown a compact globular fold, with one face particularly rich in arginine residues acting as a heparin - binding epitope, this site was recently shown to be involved in the inhibition of induced angiogenesis. experimental studies show that recombinant endostatin specifically inhibits the proliferation of endothelial cells in a dosedependent fashion. recombinant endostatin from bacteria is largely insoluble, but still efficient in arresting tu mor growth after injection into mice. intermittent therapy with recombinant bacterially produced endostatin reduces several experimental tumors, including lewis lung carcinoma, to a dormant state. no sign of drug induced resistance has been reported and, in the original study, the treatment dormancy appeared to persist even when therapy was discontinued. sowe regard endostatin as a promising anti - tumor drug
許多研究表明重組內皮抑素特異性抑制內皮細胞增殖，而且這種抑制作用呈劑量依賴性。細菌表達產物內皮抑素大部分以不溶形式存在，將這種混懸液注射治療老鼠仍可以抑制腫瘤生長。于小鼠皮下重復注射內皮抑素重組蛋白，幾乎完全抑制鼠lewis肺癌等多種腫瘤生長，並無耐藥性產生，即使中斷治療腫瘤也不再復發。Lymphotoxin ( lt ) is a kind of pleiotropic lymphocyte - secreted cytokine which mediates a large variety of inflammatory, immunostimulatory, and antiviral responses. in order to increase the antitumor activity of lymphotoxin and reduce its side effects, the recombinant plasmid pet36b - lt 27 was constructed to express soluble fusion protein cbd - lt 27. the active form of lt 27 could be collected directly with several simple steps by three kind of components on the expressed fusion protein
本研究通過構建表達n端缺失27個氨基酸的淋巴毒素融合蛋白的重組質粒，在大腸桿菌中實現融合蛋白的可溶及分泌表達，同時利用表達載體上的幾種特殊序列經簡單的分離純化步驟直接獲得大量的有生物活性的淋巴毒素缺失體lt 27 ，為尋找一種高抗腫瘤活性、低臨床毒副作用的生物抗癌藥物進行了有效的探索。
