Abrin is one of the potent toxins isolated from the beans of plant abrus precatorius.the toxic protein consists of two disulfide-bonded subunits,the a and b chains.the b chain is a galactose-specific lectin that facilitates the binding of abrin to the cell membrane that precedes endocytosis.after entering the cells,the a chain catalytically inactivates 60s ribosomal subunits by removing adenine position 4324 of 28s r–rna,and thereby inhibits protein biosynthesis.

They include the variation of the degradement velocity of different sample, the inhibition product of PCR, the amount of DNA extraction, quality of DNA and the heteroplasmy of some tissue. Correct sequencing, comparison of the result of forward and reverse primers sequencing should be done to rule out wrong signals, and prevent contamination. In addition to gene sequencing, low grade heteroplasmy could be dealt by Denaturing high performance liquid chromatography. Multiplex Ligation-dependent Probe Amplification. The analysis of mitochondrial HV Ⅰ, HV Ⅱ sequencing is able to identify the maternal sanguinity, then it could assist in the human identification. It also complements the genomic STR system in distribution of population, the origin of human, and analysis for fossil.

CaN Aβ gene silencing can reduce myocardial hypertrophy in cultured cells, si1280 (21bp) of CaN Aβ gene is the most effective target site for siRNA. The method of intrapericardial injection of plasmid, microbubbles and erzymes can improve transfection efficiency of non-viral plasmid with satisfying targeted transfection. But the scope of transfected myocytes is still limited. CaN Aβ shRNA expressing plasmid transfection in vivo by pericardial injection results in decreased CaN Aβ protein expression of small part of myocytes, and CaN Aβ mRNA only shows decreased trend. The dosage of non-viral vector and the parameters of ultrasound energy should be optimized in further study.
结论RNAi技术抑制CaN Aβ基因表达可有效减轻Ald诱导的心肌细胞肥大程度;CaN Aβ基因中si1280(21bp)片段为实现RNAi的更有效片段;微泡+酶类心包腔内注射超声导入的方法可有效改善非病毒载体在体心肌的转染效率,同时具有一定的靶向性,但总的转染范围仍然有限;采用这一方法进一步进行&一肾一夹&心肌肥大模型大鼠在体心肌细胞的CaNAβ的RNAi干预,发现心肌肥大大鼠心外膜下局部心肌细胞CaN Aβ蛋白水平降低,CaN AβmRNA水平虽有下降趋势,但无统计学差异,提示质粒的用量及超声导入的参数有待进一步研究使其优化。

Glioma is still one of refractory disease in the neurosurgical field; the development of new primary and adjuvant treatment is vital. Recently, the gene therapy of glioma is developed rapidly and there are many methods about the gene therapy that include: suicide gene therapy, immunologic gene therapy, drug resistangce gene therapy, angiostatin gene therapy and so on. The sucide gene therapy is the most potential approach of antitumer, these nonmammalian genes encode enzyme that convert nontoxic prodrugs into highly toxic metablites. Cells transfected with suicide genes are targeted for specific negative selection, witch can be induced by administrtion of the corresponding produg. Among the enzyme/produg combinations, two of the best characterized system are herpes simplex virus thymidine kinase /ganciclovir and Escherichia coli cytosine deaminase /5-flourocytosine (5-FC). The formor can convert the antiviral nucleoside analogs acyclovir , ganciclovir to their nucleoside monophosphate derivatives, the monophosphate forms are subsequently phosphorylated by endogenus cellular kinases to triphosphates, these molecules are potent inhibitors of DNA synthesis.
近年来脑胶质瘤的基因治疗发展迅速,应运而生的方法有自杀基因、免疫基因、多药耐药基因以及抗血管生成基因等,其中自杀基因被认为是最有前景的基因治疗方法,它又称病毒介导的酶/药物前体疗法,是利用转基因技术将哺乳动物细胞中所不含有的自杀基因转入到哺乳动物肿瘤细胞中,该基因表达的产物可将无毒的药物前体转化为毒性药物,从而选择性杀伤该肿瘤细胞,常用的自杀基因有单纯疱疹病毒-胸苷激酶基因和大肠杆菌胞嘧啶脱氨酶基因,前者催化无毒性抗病毒核苷类似物如丙氧鸟苷、无环鸟苷等成为单磷酸核苷衍生物,然后在内源性细胞激酶作用下转化为具有明显毒性的三磷酸核苷,作为DNA合成链的终止剂和DNA合成酶的抑制剂,干扰细胞DNA的合成;后者编码的胞嘧啶脱氨酶可催化5-氟胞嘧啶(5-FC)脱氨成为5-氟尿嘧啶(5-FU),然后代谢为有毒性的5-氟尿嘧啶-5′三磷酸(5-FUTP)和5-氟-2′脱氧尿嘧啶-5′磷酸(5-FdUTP),5-FUTP通过与UTP竞争性结合而抑制mRNA和tRNA的合成,5-FdUTP则作用于胸苷合成酶,导致TMP衰竭而阻止DNA的合成,最终诱导肿瘤细胞凋亡。
