    • 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.
    • 本发明一般涉及使用内含子微RNA样RNA试剂的转基因表达来开发,产生和选择人胚胎干(hES)样多能细胞的方法。 更具体地说,本发明涉及一种用于产生非天然存在的内含子及其内含子组分的方法和组合物,其能够在哺乳动物细胞中加工成mir-302样RNA分子,从而诱导对分化 - 相关和命运决定基因,导致将细胞重编程为多能胚胎干(ES)细胞样状态。 如此获得的ES样细胞强烈表达hES细胞标志物,例如Oct3 / 4,SSEA-3和SSEA-4,并且可以通过在饲养层上处理某些激素和/或生长因子而被引导到各种组织细胞类型中, 体外免疫细胞培养条件,可用于移植和基因治疗。 因此,本发明提供了一种简单,有效和安全的基因操作方法,用于不仅将体细胞重编程为ES样多能细胞,而且有助于在无饲养细胞培养条件下维持ES细胞的多能性和更新性质,预防 将以前的iPS方法中使用的四个大转录因子基因的繁琐的逆转录病毒插入一个单细胞中。

    • This invention relates to a composition and its use for formulating nucleic acid-based drugs/vaccines with sugar alcohol compositions into complexes for both in-vitro and in-vivo delivery. Particularly, the present invention includes the ingredients and processes necessary for formulating therapeutic and pharmaceutical nucleic acid compositions, such as miRNA, microRNA precursors, shRNAs, siRNAs, ribozymes, antisense RNAs/DNAs, RNA-DNA hybrids and DNA vectors/vaccines, with glycylated sugar alcohols/sugars into delivery complexes, which can then be absorbed by cells in vivo and in vitro via active endocytosis. Also, the present invention discloses that chemical compounds containing sugar alcohol- and/or sugar-like structures can protect nucleic acids, in particular miRNAs, shRNAs, siRNAs and ribozymes, from degradation in vivo as well as in vitro. Therefore, the present invention is also a formula and method for preserving the structural integrity and functional efficacy of these nucleic acid-based drugs and/or vaccines in vivo and in vitro.

    • This invention generally relates to a composition for developing novel anti-cancer drugs and/or vaccines and producing microRNA precursor (pre-miRNA) and/or its shRNA homologues/mimics/derivatives, and a method thereof. The present invention also relates to a use of a composition in producing novel prokaryote-produced microRNA precursor (pro-miRNA) capable of being delivered into human cells and processed by the cells into microRNA-like effectors to elicit specific silencing effects on certain targeted oncogenes, subsequently leading to a therapeutic result of tumor suppression and cancer therapy. Specifically, the method of the present invention includes inducing an expression of the pre-miRNA/pro-miRNAs, particularly human pre-miR-302, in prokaryotes through pol-2 or pol-2-like RNA promoter. Most importantly, the composition of the present invention is further a novel pre-miRNA-based drug that is capable of reprogramming the malignant properties of high-grade human liver cancers into a low-grade benign or even relatively normal stage—a mechanism called “Cancer Reversion”.
