    Abstract: This invention generally relates to a composition and method of using recombinant microRNAs (miRNA) and their hairpin-like precursors (pre-miRNA) as therapeutic drugs for treating Alzheimer's diseases (AD). More specifically, the present invention relates to the use of man-made miRNA miR-302 precursors (pre-miR-302) for AD therapy in humans. These pre-miR-302 molecules can be mass produced in prokaryotes as a form of DNA expression-competent DNA vectors and/or hairpin-like RNAs. As prokaryotic cells do not transcribe or process hairpin-like RNAs, the present invention also teaches a method for expressing pre-miRNAs in prokaryotes, i.e. pro-miRNA, using a novel hairpin-like RNA transcription mechanism newly found in prokaryotes. Additionally, since miR-302 is a well-known embryonic stem cell (ESC)-specific factor in humans, our novel findings of this invention can be further used to advance the designs and development of novel regenerative medicine for treating many other ageing-related degenerative diseases, such as Parkinson's diseases, osteoporosis, diabetes, and cancers.

    Abstract: This invention generally relates to a composition and its method of use for inducing adult stem cell (ASC) expansion and/or derivation in vitro, using miR-302-like pre-miRNAs, shRNAs and/or siRNAs, all of which contain a shared sequence of 5′-UAAGUGCUUC CAUGUUU-3′ (SEQ ID NO: 7) in the 5′-end, and further in conjunction with the use of some wound-healing-related defined factors, including but not limited to basic fibroblast growth factor (bFGF)/fibroblast growth factor 2 (FGF-2), leukemia inhibitory factor (LIF), insulin-like growth factor (IGF), Epidermal growth factor (EGF), platelet-derived growth factor (PDGF), vascular endothelial growth factor (VEGF), transforming growth factor (TGF), tumor necrosis factor (TNF), stem cell factor (SCF), homeobox proteins (HOX), Notch, GSK, Wnt/beta-Catenin signals, interleukins, and/or bone morphogenetic proteins (BMPs). The principle of the present invention is related to a novel mechanism of inducible symmetric ASC division recently found in a skin wound healing model in vivo. The resulting amplified ASCs are useful for treating a variety of human aging- and cell dysfunction-associated disorders, including but not limited to Alzheimer's disease, Parkinson's disease, motor neuron disease, stroke, diabetes, osteoporosis, myocardial infraction, hemophilia, anemia, AIDS, leukemia, lymphoma and many kinds of cancers as well as aging.

    Abstract: This invention relates to a novel modified RNA composition (called oxo-RNA) comprising at least an oxo-nucleotide (containing oxopurine) in its 3′-end region (e.g. 3′-tail, 3′-UTR). The oxo-nucleotide includes 8-hydroxyguanine/8-oxoguanine/7,8-dihydro-8-oxoguanine (or called oxo-G/oxo-dG) and 8-hydroxyadenine/8-oxoadenine (or called oxo-A/oxo-dA). Oxo-RNA can be a single-stranded RNA sequence or double-stranded duplex, or even an RNA-DNA hybrid duplex. Advantageously, this new oxo-RNA composition not only greatly enhance RNA/DNA stability and functionality but also can prevent TREX1-mediated degradation and the related non-specific immunity over-activation (e.g. cytokine storm). Most importantly, the constructs of oxo-RNA can be designed to mimic antisense RNA oligonucleotide (aRNA-ASO), small interfering RNA (siRNA), short hairpin RNA (shRNA), microRNA (miRNA) mimic, microRNA precursor (pre-miRNA), double-stranded RNA (dsRNA), RNA-DNA hybrid, long noncoding RNA (IncRNA), small activating RNA (saRNA), messenger RNA (mRNA), and/or self-amplifying RNA/mRNA (saRNA/samRNA), or a combination thereof.

    Abstract: This invention relates to a novel composition of RNA/mRNA medicines and/or vaccines produced by using Replicase/RNA-dependent RNA polymerase (RdRP)-mediated RNA Cycling Reaction (RCR). This RCR-amplifiable RNA/mRNA composition comprises at least a replicase/RdRP-binding site (RdRP-BS) in the 5′-end or 3′-end, or both, of a desired RNA sequence of interest, to form a self-amplifying RNA/mRNA (samRNA) platform. The samRNA platform so obtained is useful for designing and developing a variety of self-amplifying RNA/mRNA (samRNA) constructs, of which the desired RNA sequences may include, but not limited to, antisense oligonucleotide RNA (aRNA; ASO), small interfering RNA (siRNA), short hairpin RNA (shRNA), microRNA (miRNA)/miRNA precursor (pre-miRNA), long non-coding RNA (lncRNA), and/or messenger RNA (mRNA), or a combination thereof. The present RdRP-BS designs in said samRNA are derived or modified from the identified RdRP-BS motifs of coronavirus (e.g. SARS-CoV-2-associated viruses) and/or hepatitis C virus (HCV) in either single-stranded or double-stranded conformation, or a combination thereof.

    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.

    Abstract: This invention relates to a novel mRNA composition and its production method useful for developing and manufacturing RNA-based anti-viral and/or anti-cancer vaccines and medicines. This invention includes two types of mRNA constructs, namely “5′-hairpin messenger RNA (5hmRNA)” and “messenger-hairpin-messenger RNA (mhmRNA)”, respectively. Both of 5hmRNA and mhmRNA contain at least a hairpin-like stem-loop RNA structure. The 5hmRNA contains at least a stem-loop RNA structure in the 5′-UTR of a protein/peptide-coding mRNA, while the mhmRNA contains a middle stem-loop structure flanked with two protein/peptide-coding mRNA sequences on both sides. In mhmRNA, the first 5′-mRNA preferably encodes an RNA replicase, for amplifying the second 3′-mRNA in transfected cells. After transfection into target cells, 5hmRNA and mhmRNA can be further translated into at least a desired protein/peptide. To produce highly structured 5hmRNA and mhmRNA, a novel PCR-IVT methodology has been developed and used with a specially designed RNA polymerase-helicase mixture reaction
