HuidaGene Therapeutics creates world’s first guanine base-editor
HuidaGene Therapeutics, a clinical-stage genome-editing company, says the National Science Review has published data from its study of the world’s first DNA base editor converting guanine to cytosine/thymine (pyrimidine), or G-to-Y. The company has filed an international patent application for the glycosylase-based guanine base editor (gGBE) and owns the exclusive…

That morning, Liu…
Multiplexed base editing through Cas12a variant-mediated cytosine and adenine base editors
Robust C-to-T conversion by Cas12a variant-mediated CBEs for non-canonical PAMs We initially attempted to screen for optimal cytosine deaminases that confer powerful C-to-T editing for Cas12a-mediated CBEs. Seven dCas12a-CBEs fused with individual cytosine deaminases1,2,16,20,21,22,24,25,26 were compared in HEK293T cells and porcine embryos at sites with TTTV PAM sequences. The dCas12a-A3A…
In Allogeneic T-ALL Cells, Cytosine Base Editing Allows Quadruple Editing
Allogeneic chimeric antigen receptor T-cell (CART) treatments need several gene alterations to be therapeutically feasible. Unfortunately, the majority of allogeneic CARTs were produced utilizing gene editing methods that cause DNA double-stranded breaks (DSBs), which can have undesired on-target editing results and unanticipated effects. As opposed to clustered regularly interspaced short…
High-purity production and precise editing of DNA base editing ribonucleoproteins
Abstract Ribonucleoprotein (RNP) complex–mediated base editing is expected to be greatly beneficial because of its reduced off-target effects compared to plasmid- or viral vector–mediated gene editing, especially in therapeutic applications. However, production of recombinant cytosine base editors (CBEs) or adenine base editors (ABEs) with ample yield and high purity in…
