The hemagglutinating virus of Japan (HVJ) fused with liposomes provides a unique transfection vehicle with characteristics of both virus vector and liposome. Here we investigate the efficiency and safety of the HVJ-liposome technique in delivering foreign genes and oligonucleotides into the lung of the Wistar rat. A plasmid vector containing the Escherichia coli beta-galactosidase (beta-gal) gene and the chicken beta-actin promoter was transfected via the trachea using the HVJ-liposome method. Cytochemical staining showed expression of exogenous beta-gal activity in airway epithelial cells, alveolar macrophages, and alveolar type II cells. This activity persisted at least 28 days after administration of the genes. FITC-labeled oligonucleotides also were introduced into the same types of lung cells as those expressing beta-gal. After instillation of HVJ-liposome, anti-HVJ antibodies were detected in the sera of the rats, but even after repeated administration of HVJ-liposome, no marked histopathologic change was observed while exogenous beta-gal expression was detected in pulmonary cells.

The cytogenetical reaction of human peripheral lymphocytes to okadaic acid and calyculin A was examined. Calyculin A could induce PCC about 20 times more effectively than okadaic acid. Their mechanisms of PCC induction were judged similar by their dose-dependent manner and chromosome morphology. Contrary to earlier studies suggesting that chemicals could not induce PCC in G1 cells where little cyclin B is present, the present study showed that calyculin A could induce PCC in lymphocytes not only at S and G2/M but also at the second G1 phase after PHA stimulation in vitro. PCC was induced slightly in lymphocytes both at G0 and the first in vitro G1 phase even when the calyculin A concentration increased one hundred fold. It was found that calcium ionophore A23187 increased frequencies of G0-PCC induced by calyculin A, although a further refinement is necessary to obtain a suitable morphology of G0-PCC for cytogenetic studies.

观察了人外周血淋巴细胞对冈田酸和calyculin A的细胞遗传学反应。Calyculin A诱导PCC的效果是冈田酸的20倍。从它们的剂量依赖性和染色体形态判断它们诱导PCC的机制相似。与早期研究表明化学物质不能在细胞周期蛋白B较少的G1细胞中诱导PCC相反,本研究表明,calyculin A不仅可以在S和G2/M阶段诱导淋巴细胞PCC,而且在体外PHA刺激后的第二G1期也可以诱导PCC。即使calyculin A浓度增加100倍,淋巴细胞在G0期和体外第一G1期均有轻微的PCC诱导。发现钙离子载体A23187增加了calyculin A诱导的G0-PCC的频率,尽管需要进一步细化以获得适合细胞遗传学研究的G0-PCC形态。

A number of human homologues of yeast cell cycle checkpoint control genes have been identified recently. In this study, the sequence alterations in six of such novel human genes (hRAD1, hRAD9, hRAD17, hHUS1, CHK1 and CHES1) were analyzed by PCR-single-strand conformational polymorphism (PCR-SSCP) method on a panel of 25 human tumor cell lines in an attempt to search for possible in vivo cases where any of the checkpoint-related genes are altered in human systems. For hRAD9, hHUS1 or CHK1, no SSCP variant was detected in any of the cell lines tested, indicating a high stability of these genes in human cancer. Most of the SSCP variants found in the other three genes were due to single nucleotide base substitutions. Two cell lines were found to be homozygous for missense-type base substitutions, i.e., Saos-2 was homoallelic for 1637T-->G in hRAD17; and COLO320DM for 1189G-->A in CHES1, indicating a possible use of these cell lines for further study. The former nucleotide change in hRAD17, which causes a change of amino acid from arginine to lysine at codon 546, was supposed to be polymorphic. Considering that lysine, but not arginine, is the amino acid that is well conserved among fission yeast, mouse and monkey at the corresponding position, coexistence of both alleles in human may have a functional or selectional implication.

近年来已经发现了许多酵母细胞周期检查点控制基因的人类同源物。本研究采用pcr -单链构象多态性(PCR-SSCP)方法,在25个人类肿瘤细胞系中分析了6个新的人类基因(hRAD1、hRAD9、hRAD17、hHUS1、CHK1和CHES1)的序列变化,试图寻找人体系统中可能存在的检查点相关基因改变的体内病例。对于hRAD9、hHUS1或CHK1,在所有测试的细胞系中均未检测到SSCP变异,表明这些基因在人类癌症中的高度稳定性。在其他三个基因中发现的大多数SSCP变异是由于单核苷酸碱基替换。两个细胞系在缺失型碱基替换上发现纯合子,即Saos-2在hRAD17中是1637T- >G的同等位基因;和COLO320DM用于CHES1中的1189G- >A,表明这些细胞系可能用于进一步研究。hRAD17的前一个核苷酸变化导致密码子546处的氨基酸从精氨酸变为赖氨酸,这被认为是多态的。考虑到赖氨酸而非精氨酸是裂变酵母、小鼠和猴子在相应位置保存较好的氨基酸,这两种等位基因在人类中共存可能具有功能或选择意义。

RNA helicase A is the homolog of the Drosophila maleless protein, an essential factor involved in dosage compensation, and plays a crucial role in early development in mammals. Here, we have mapped the human RNA helicase A (DDX9) gene to the major susceptibility locus for prostate cancer at chromosome band 1q25, and its pseudogene (DDX9P) to the band 13q22 by fluorescence in situ hybridization, somatic cell hybrid analysis, and assignment of YAC clones, respectively.

Many anticancer drugs inhibit DNA replication. To investigate the mechanism of permanent growth inhibition after transient arrest of DNA replication, we selected genetic suppressor elements (GSEs) conferring resistance to replication inhibitor Aphidicolin. Starting from a retroviral expression library carrying normalized fragments of human cell cDNA, we isolated four GSEs which, when introduced as a combination, produced resistance to Aphidicolin, doxorubicin and hydroxyurea in HT1080 fibrosarcoma cells. The four GSEs were derived from ORFX bromodomain protein gene, WIZ zinc finger protein gene, the gene for subunit 3 of cytochrome c oxidase, and the gene corresponding to an EST with no known function. A cell line carrying all four GSEs showed a weaker induction of the senescence-like phenotype after treatment with Aphidicolin or doxorubicin; the resistance of this cell line was not associated with decreased doxorubicin accumulation. These results indicate that combined effects of GSEs derived from these four genes increase cellular resistance to replication-inhibiting drugs, possibly by inhibiting drug-induced senescence.

许多抗癌药物抑制DNA复制。为了研究DNA复制短暂停止后永久生长抑制的机制,我们选择了对复制抑制剂Aphidicolin具有抗性的基因抑制元件(GSEs)。从携带规范化人类细胞cDNA片段的逆转录病毒表达文库开始,我们分离出四种gse,当它们作为组合引入HT1080纤维肉瘤细胞时,产生了对阿飞霉素、阿霉素和羟基脲的抗性。这4个gse分别来源于细胞色素c氧化酶3亚基基因ORFX溴结构域基因、WIZ锌指蛋白基因和一个功能未知的EST对应基因。携带所有四种GSEs的细胞系在阿霉素或阿霉素处理后显示较弱的衰老样表型诱导;该细胞系的耐药性与阿霉素积累的减少无关。这些结果表明,来自这四个基因的GSEs的联合作用可能通过抑制药物诱导的衰老来增强细胞对复制抑制药物的抗性。

The four GSEs were derived from ORFX bromodomain protein gene, WIZ zinc finger protein gene, the gene for subunit 3 of cytochrome c oxidase, and the gene corresponding to an EST with no known function. A cell line carrying all four GSEs showed a weaker induction of the senescence-like phenotype after treatment with Aphidicolin or doxorubicin; the resistance of this cell line was not associated with decreased doxorubicin accumulation. These results indicate that combined effects of GSEs derived from these four genes increase cellular resistance to replication-inhibiting drugs, possibly by inhibiting drug-induced senescence.</p>","PeriodicalId":21884,"journal":{"name":"Somatic Cell and Molecular Genetics","volume":"25 1","pages":"9-26"},"PeriodicalIF":0.0,"publicationDate":"1999-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1023/b:scam.0000007136.49230.b3","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21765529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
