    • Patterns of microRNA (miRNA) expression are correlated to the degrees of tumor cell differentiation in human prostate cancer. MiRNAs can complementarily bind to either oncogenes or tumor suppressor genes, resulting in targeted gene silencing and thus changes of cellular tumorigenecity. Using miRNA microarray analysis, 8 down-regulated and 3 up-regulated known miRNAs in androgen-independent human prostate cancer cell lines, such as LNCaP C4-2B and PC3, compared to those androgen-dependent cell lines, such as LNCaP and PC3-AR9 were consistently detected. Fluorescent in-situ hybridization assays in human prostate cancer tissue arrays containing sixty patients at different stages also showed the same miRNA expression patterns in hormone-refractory prostate carcinomas (HRPC) compared to androgen-sensitive non-cancerous prostate epithelium. In-vitro tumorigenecity assays using one of the identified miRNAs, mir-146a, were performed to provide validation of its function in prostate cancer. Gain-of-function transfection of mir-146a markedly suppressed its targeted ROCK1 gene expression in androgen-independent PC3 cells, consequently resulting in reduced cancer cell proliferation, invasion and metastasis to human bone marrow endothelial cell monolayers. Since ROCK1 is the key kinase for activating hyaluronan-mediated HRPC transformation in vivo and in PC3 cells, mir-146a should function as a tumor-suppressor gene in modulating the ROCK1-associated tumorigenecity.
    • microRNA(miRNA)表达的模式与人类前列腺癌的肿瘤细胞分化程度相关。 MiRNA可以互补结合癌基因或肿瘤抑制基因,导致靶向基因沉默,从而导致细胞致瘤性的变化。 与雄激素依赖性细胞系(如LNCaP和PC3)相比,使用miRNA微阵列分析,8个下调和3个上调已知的与雄激素非依赖性前列腺癌细胞系(如LNCaP C4-2B和PC3)的miRNA相比, 一直检测到AR9。 与雄激素敏感的非癌前列腺上皮相比,含有60位不同阶段患者的人类前列腺癌组织阵列中的荧光原位杂交测定也显示与激素难治性前列腺癌(HRPC)相同的miRNA表达模式。 使用鉴定的miRNA之一的mir-146a进行体外肿瘤发生测定,以提供其在前列腺癌中的功能的验证。 mir-146a功能的功能转染显着抑制雄激素依赖性PC3细胞中靶向的ROCK1基因表达,从而导致癌细胞增殖,侵袭和转移到人类骨髓内皮细胞单层。 由于ROCK1是在体内和PC3细胞中激活透明质酸介导的HRPC转化的关键激酶,因此mir-146a应该作为调节ROCK1相关致瘤性的肿瘤抑制基因起作用。

    • Excess amount of modified subtracter DNA from control cells is generated by carboxylating the base structures of its certain nucleotides with chemical agents in order to introduce covalent affinity between the modified subtracter and a non-modified tester DNA. Hybridization of the control subtracter and the experimental tester DNA is performed with a heat-melting and then cool-reassociation technique. While the desired different (heterologous) sequences remain in the form of hydrogen-binding, common (homologous) sequences of the hybridized DNA are covalently bonded to each other. Since the covalent bonding of the common sequences can not be broken during a polymerase chain reaction, resulting in no amplification of the common sequences but great amplification of the desired different sequences. The desired DNA sequences present after such covalent homologue subtraction and selective amplification represent those DNA sequences which only exist in the tester but not in the subtracter DNA library.

    • The present invention provides a method for fast, simple, and reliable isolation of desired different sequences from two DNA libraries. Excess amount of nucleotide analog-containing DNA subtracter from control cells is generated by incorporating nucleotide analog with a template-dependent extension reaction to introduce susceptible-sites for subsequent enzymatic digestion. Hybridization of the control subtracter and experimental DNA is performed with a heat-melting and then cool-reassociation technique. The hybridized DNAs are subtracted with nucleotide analog-removing enzyme first, resulting in nicking or gapping all nucleotide analog-containing hybrid duplexes which are further digested by single-strand-specific nuclease. Desired DNA sequences from the experimental cells, but not the control ones stay intact throughout the digestion procedure and can be selectively amplified at the end. This technique is designed for the subtractive hybridization of different sequences between two DNA libraries from distinct cell sources and will allow more efficient isolations in experiments on cancer formation, development of gene therapy, and understanding of pathological status and developmental regulation.

    • The present invention provides a fast, simple and specific method for generating a complete full-length cDNA library from single cells. The first reverse transcription of intracellular mRNAs with an oligo(dT)n-promoter primer introduces a recognition site for following transcription of newly reverse-transcribed cDNAs. The poly-nucleotide tailing of above cDNAs in addition to aforementioned promoter region further forms binding templates for specific PCR amplification. After repeating the reverse transcription, transcription, reverse transcription and PCR procedure, we can multiply a single copy of mRNA to two billion folds by calculation based upon the comparison between the amount of a synthesized cDNA library and that of theoretically presumed mRNAs within a cell (0.1 pg). In conjunction with a cell fixation and permeabilization step, the complete full-length cDNA library can be directly generated from few single cells without mRNA degradation. The present invention will be very useful in preparing tissue-specific full-length cDNA libraries for future gene chip technology.

    • The present invention provides a simple, specific and nontoxic gene knock-out method by formation of covalently bonding between modified probes and targeted sequences. When covalently modified first strand probes are hybridized with a second strand of targeted gene transcripts, certain modified bases of said first strand will interact with natural bases of said second strand to form covalent bonds by which the translation of said second strand is inhibited. Because the hybridization of said two strands generates covalent base-pairing only between their complementary homology region(s), such specificity increases the targeting efficiency of a gene knock-out system. Also, because neither a polymerase extension reaction nor a nuclease digestion can be performed through the covalently bonded region(s) of aforesaid hybrids, the present invention in conjunction with a delivery method can be used to inactivate intracellular functions of targeted nucleotide sequences, to inhibit viral infections in vivo and to increase binding stability of antisense drugs in a gene therapy.

    • This invention generally relates to a method for developing, generating and selecting human embryonic stem (hES)-like pluripotent cells using transgenic expression of intronic microRNA-like RNA agents. More particularly, the present invention relates to a method and composition for generating a non-naturally occurring intron and its intronic components capable of being processed into mir-302-like RNA molecules in mammalian cells and thus inducing certain specific gene silencing effects on differentiation-related and fate-determinant genes of the cells, resulting in reprogramming the cells into a pluripotent embryonic stem (ES)-cell-like state. The ES-like cells so obtained are strongly express hES cell markers, such as Oct3/4, SSEA-3 and SSEA-4, and can be guided into various tissue cell types by treating certain hormones and/or growth factors under a feeder-free cell culture condition in vitro, which may be used for transplantation and gene therapies. Therefore, the present invention offers a simple, effective and safe gene manipulation approach for not only reprogramming somatic cells into ES-like pluripotent cells but also facilitating the maintenance of pluripotent and renewal properties of ES cells under a feeder-free cell culture condition, preventing the tedious retroviral insertion of four large transcription factor genes into one single cell as used in the previous iPS methods.
