Abstract
This invention generally relates to a composition and its production method useful for developing drugs/vaccines and/or therapies against a variety of degenerative diseases in humans. Particularly, the present invention teaches the essential steps of production and purification processes necessary for producing small hairpin-like RNA (shRNA) compositions, such as microRNA precursors (pre-miRNA) and short interfering RNAs (siRNA), which are useful for treating human ageing related diseases, such as, but not limited, Alzheimer's diseases, Parkinson's diseases, osteoporosis, diabetes, and cancers. The novelty of the present invention is to create an artificially enhanced adaptation environment for prokaryotic cells to adopt eukaryotic pol-2 and/or pol-2-like promoters for transcribing desired ncRNAs and/or their precursors without going through error-prone prokaryotic promoters, so as to improve the productive efficiency and reading fidelity of the shRNA transcription in the prokaryotic cells. The resulting shRNAs, preferably pre-miRNAs and siRNAs, are useful for developing therapeutic drugs against human degenerative diseases, particularly through a mechanism to induce CD34-positive stem cell expansion and/or regeneration.
