pSV—2neo和HPV—Ⅱ DNA共同转染NIH3T3细胞的结果

本实验将neo及HPV-11两种DNA共同转染NIH 3T3细胞,以G418抗生素作为选择剂,对诱导的转化灶进行筛选。同时还就G418对NIH 3T3细胞的毒性进行了观察。neo单独使用诱导的转化灶数为44.00/1×10~5;neo与HPV-11合用诱导的转化灶数为162.66/1×10~5。由neo转化的细胞含有neo基因,由neo和HPV-11转化的细胞内含有该两种基因。     

大鼠前列腺上皮细胞角蛋白8mRNA表达调节的定位研究

本文应用反义ＲＮＡ探针原位杂交法，研究雄激素对大鼠腹侧前列腺上皮细胞角蛋白８ ｍＲＮＡ表达的影响，发现１，在任何ＶＰ组织切片中，ＣＫ８探针专一、大量任何ＶＰ组织切片中，ＣＫ８探针专一、大量定位于ＶＰ腺上皮细胞中，ＣＫ８ ｍＲＮＡ是前腺上皮细胞特而灵敏的标志。２。去睾大鼠ＶＰ ＣＫ８ ｍＲＮＡ染色增强，提示ＣＫ ８ｍＲＮＡ有过度表达，注射雄激素又可抑制其过度表达，注射雄激素又可抑制其过度表达。３。与     

Evolutionary conservative phenomena in eukaryotic cells and evolutionary cell biology

Ⅰ.The significance of evolutionary viewpoint in cell research and the evolutionary conserva-tive phenomena at cellular and subcellular levelsEvolutionary theory is one of the fundamental principles of modern biology,and there-fore,the evolutionary viewpoint is one of the basic viewpoints in the research of biologi-cal problems. In living organisms,all the organic structures at various levels,from macro-molecules(nucleic acids,proteins and polysaccharides),the complexes of macro-molecules(nucleosomes,ribsomes,membranes),organelles,cells,tissues, organs,systems,up to organisms,are all the results of evolution.The mode and the mechanism
