Abstract:
The present invention provides a novel artificial sgRNA having an activity equal to or higher than that of a natural form sgRNA and improved in stability in vivo, and an efficient CRISPR/Cas9 system by combining the artificial sgRNA and Cas9. Even when a nucleotide linker region for forming a single strand by linking the 3'-terminal of crRNA and the 5'-terminal of tracrRNA in sgRNA is substituted with an amino acid derivative linker, an activity equal to or higher than that of the original sgRNA is retained in an in vitro DNA cleavage assay. Furthermore, even when the linker region existing between stem-loop 1 and stem-loop 2 of tracrRNA and/or the loop portion of stem-loop 2 are/is substituted with an amino acid derivative linker, or even when an amino acid derivative linker is added/inserted into the vicinity of the 5'-terminal and/or the 3'-terminal of sgRNA, an activity equal to or higher than that of the original sgRNA is retained. The stability in vivo can be improved by introducing one or more amino acid derivative linkers into sgRNA.
Abstract:
A method of enhancing binding of cells to an integrin-binding ligand comprises treating integrin-expressing cells in vitro with an agonist of integrin, wherein the integrin is selected from the group consisting of α4β1, α5β1, α4β7, αvβ3 and αLβ2, and contacting the treated cells with an integrin-binding ligand; integrin agonist compounds having the general formula I; methods of treating integrin-expressing cells with such agonists to enhance binding; and therapeutic methods comprising administering agonist-treated cells or agonist compounds to a mammal.
