近年来,人们研究了各种外源性核酸对肿瘤细胞的作用,例如,免疫核糖核酸(iRN-A)可激活淋巴细胞去攻击瘤细胞;淋巴组织的双股 RNA 对瘤细胞有一定毒性并抑制其生长,还有淋巴组织 RNA 不经淋巴细胞介导而直接杀伤瘤细胞等。我们曾在外源性 RNA 对 EAT、S180、P_388等三种瘤细胞的影响实验中,发现牛胰RNA 比脑、胸腺、脾组织 RNA 更显著地抑制瘤细胞的生长和分裂,并有改变瘤细胞形态的作用。不仅如此,胰 RNA 的收获量也比
In recent years, people have studied the effects of various exogenous nucleic acids on tumor cells. For example, immune RNA (iRN-A) can activate lymphocytes to attack tumor cells; double-stranded RNA of lymphoid tissues is toxic to tumor cells and Inhibit its growth, and lymphoid tissue RNA directly kills tumor cells without lymphocyte mediated. We tested the effect of exogenous RNA on three kinds of tumor cells such as EAT, S180, and P_388 and found that bovine pancreatic RNA inhibited the growth and division of tumor cells more significantly than brain, thymus, and spleen RNA and changed the tumor cells. The role of morphology. Not only that, pancreatic RNA harvested also
