Abstract: RVDs with recognition preferences for 5mC, 5hmC and 6 mA and different binding properties to these epigenetic modifications are identified in this present invention. Methylation-dependent gene activation, efficient genome editing, targeted detection of 5hmC and other applications can be achieved by using these RVDs. The present invention therefore provides an isolated DNA binding polypeptide containing TALEs, a fusion protein, a polynucleotide, a vector comprising the polynucleotide and a host cell, and the use of the protein comprising TALE repeats domain in the preparation of a reagent for detecting a methylated base in a target sequence of a gene of interest, as well as a method for targeting and binding to a target sequence of a gene of interest in a cell.

Abstract: The present application provides methods for editing RNA by introducing a deaminase-recruiting RNA in a host cell for deamination of an adenosine in a target RNA. The present application further provides deaminase-recruiting RNAs used in the RNA editing methods and compositions and kits comprising the same.

Abstract: The present application provides circular RNAs (circRNAs) encoding therapeutic polyeptides (e.g., an antigenic polypeptide, a functional protein, a receptor protein, or a targeting protein). In some embodiments, the present application provides circRNA vaccines against a coronavirus such as SARS-CoV-2. In some embodiments, the circRNA vaccine comprises a circRNA comprising a nucleic acid sequence encoding an antigenic polypeptide comprising a Spike (S) protein or a fragment thereof of a coronavirus. Also provided are methods of treating or preventing a disease or condition using the circRNAs or compositions thereof.

Abstract: A high and low temperature composite ablation surgery system, relating to the technical field of cryotherapy, used to improve the safety and effectiveness of therapy, and comprising a main unit (100) and a cryogenic-thermal ablation probe (200) connected to the main unit (100). The main unit (100) comprises a cold working medium supply system (300), a hot working medium supply system (400), and a working medium distribution system (500). The working medium distribution system (500) can respectively control the cold working medium supply system (300) to deliver a cold working medium to the cryogenic-thermal ablation probe (200) and control the hot working medium supply system (400) to deliver a hot working medium to the cryogenic-thermal ablation probe (200). Therefore, after low-temperature therapy is completed, a therapy area can be quickly rewarmed, thereby providing a basis for improving the safety, economy and convenience of the surgery.

Abstract: A donor construct and a gene knockout method, as well as a system and kit for the gene knockout are provided. The donor construct is a linear donor DNA or can be cleaved in a cell to produce the linear donor DNA. The gene knockout method uses a marker gene contained in the donor construct to enrich cells in which a gene is knocked out, thereby improving the efficiency of generating the gene knockout by a sequence-specific nuclease.
