The principal purpose of this study is to set up the isolation methods for diphtheria toxin expressed by genes, to purify the toxin with complete biological activities, and to make researches on its toxicities. In the experiments, the target gene was inserted into the cloning vectors--pET22b, then the vectors were introduced into host cells -BL21(DE3). The expression of the toxin was induced by addition of IPTG. The expression products were purified by His-6 label affinity chromatography. Then the diphtheria toxin expressed was transferred to PVC membrane using semidry blotter to determine the amino acid sequence of N-terminal. The "nicked" diphtheria toxin linked by disulfide bond was gained by protease hydrolysis.

Specifically, we will (1) perform electrophysiological study on the interaction of CTXs with cardiomyocytes stripped of specific GAGs,(2) study the binding of CTXs from spitting cobra venom with corneal tissue and examine the possible involvement of GAGs in the disruption of regular superstructure of collagen fibril and (3) examine the role of polyproline peptide sequence of P-type CTXs in the lytic action of CTXs. The results of this study will not only help delineate the mechanism of cobra CTXs, a long standing problem in the toxicity of cobra venom, but also suggest a new approach to develop CTXs into a potential drug for cancer.

Analysing ustiloxins inhibiting plant cell mitosis The inhibition experiment of growth of garlic radicle showed that there were more cells in the telophase stage in the garlic radicle dealed with culture filtrate of Ustilaginodea virens than those dealed with H2O. The cell volume of the former was bigger than that of the latter. So it seemed that ustiloxins could inhibit the cell mitosis, but not in the cell elongation.

We may well explain why ricin-induced apoptosis showed no typical DNA ladder. The presence of laddering in DNA gels implies an apoptosis process, but its absence does not rule out the apoptosis. The ricin 0.05μmol〓 had no effect on the 〓 phase of cell cycle, but induced 〓 arrest. The ricin may affect the balance of synthesis and destruction of proteins that controlling the cell cycle.

检测到DNA梯度表明细胞发生了细胞凋亡，未检测到DNA梯度不能否认凋亡的存在。0.05μmol.L〓的蓖麻毒素对HeLa细胞周期的G〓/G〓期无影响，而诱导了G〓/M期阻滞，蓖麻毒素可能引起一些控制细胞周期蛋白的合成与降解发生紊乱。
