Abstract: The present disclosure relates to the composition and process for the production of an ultra-strong, biocompatible, electroconductive, and stretchable hydrogel, which comprises: a step (a) of physical or chemical modification of natural polymers e.g., preparation of silk nanofiber and double methacrylation of gelatin; a step (b) of graphene oxide (GO) carboxylation; a step (c) of carbodiimidation between methacrylated natural polymers of step (a) and carboxylated GO of step (b); and a step (d) of three dimensional (3D) bioprinting of step (c) with/without silk nanofiber. It was found that these steps in this disclosure give rise to a biocompatible hydrogel with high mechanical strength in the range of load-bearing soft tissue such as tendon and heart as opposed to conventional hydrogels.

Abstract: Provided is a composition for the prevention or treatment of Hutchinson-Gilford Progeria syndrome (HGPS) using gene editing, which contains sgRNA that hybridizes to mRNA encoding progerin, which causes HGPS, and a gene encoding Cas13 protein acting on the same. When introduced into the cell of a subject to be treated and only the mRNA encoding progerin is selectively cut. There is no need for co-prescribing with other therapies and fewer side effects occur than traditional farnesyltransferase inhibitors (FTIs). The efficiency is higher than when treated using homologous recombination (HR) at the DNA level, treatment using composition can be made reversibly, and the composition can be applied specifically compared to targeted treatment using RNAi (RNA interference), and has fewer side effects. Compared to treatment using CRISPR/Cas9, which directly acts on DNA and produces irreversible results, treatment using composition is reversible and selectively cut only mRNA encoding progerin, thereby ensuring safety.
