    • Compositions and methods useful in the production of proteins in vitro and in vivo are provided. In particular, this invention provides bionanoparticles comprised of replication-proficient, double-stranded RNA (dsRNA) capsids which are capable of transfecting, for example, target bacterial, yeast, plant and mammalian cells, and causing expression of genes of interest in said transfected cells. The bionanoparticles comprised of replication-proficient, dsRNA capsids are also capable of expressing genes of interest in vitro. The genes of interest can encode proteins that are useful, for example, as research reagents, therapeutics and vaccines. Also described are methods that enable the construction of bionanoparticles comprised of replication-proficient dsRNA capsids and methods for transfecting cells with said bionanoparticles and expressing said genes of interest in transfected cells and in vitro.
    • 提供了在体外和体内生产蛋白质中有用的组合物和方法。 特别地,本发明提供了由能够转染例如靶细菌,酵母,植物和哺乳动物细胞以及在所述转染的细胞,酵母,植物和哺乳动物细胞中引起感兴趣的基因表达的复制精通双链RNA(dsRNA)衣壳组成的生物纳米颗粒 细胞。 由复制熟练的dsRNA衣壳组成的生物纳米颗粒也能够体外表达感兴趣的基因。 感兴趣的基因可以编码可用于例如研究试剂,治疗剂和疫苗的蛋白质。 还描述了能够构建由复制熟练的dsRNA衣壳组成的生物纳米颗粒的方法以及用所述生物纳米颗粒转染细胞并在转染细胞中体外表达所述目的基因的方法。
