Happy to share our lab's preprint! 📄 We've developed base editors with SsdAtox, a novel DYW-like deaminase from Pseudomonas syringae, effective for both ssDNA and dsDNA! #GenomeEditing#CRISPR#BaseEditing https://t.co/2XEIt79Y8F @biorxivpreprint
We've previously reported PAM variable PEmax for correcting KRAS mutations, and now our constructs - PEmax-SpG, PEmax-SpG-P2A-hMLH1dn - are available on @Addgene! Check them out! #CRISPR#PrimeEditing

1. The title of the recently published paper, "Genotoxic Effects of Base and Prime Editing in Human Hematopoietic Stem Cells," is quite catchy and unsettling. However, the few points it covers have largely been extensively studied before.

Today we report in @CellCellPress a suite of engineered and PACE-evolved prime editor variants PE6a-g. These new prime editors improve the activity, in vivo deliverability, and in vivo editing efficiency of prime editing.

A typical human cell expresses ~150-400 transcription factors. These proteins bind to DNA to regulate gene expression.
And >half of them also bind RNA.
Prior studies have shown that a "few TFs" bind RNA, but this one finds many more. (h/t @alectricity)

A #CRISPR prime editing approach from @Yongsub__Kim corrects all types of G12 and G13 oncogenic KRAS mutations using a universal pegRNA, demonstrating the potential of applying this system to KRAS gene therapy through a one-to-many approach.

Since the discovery of CRISPR-Cas systems, people have wondered if a similar type of system exists in eukaryotes. Today, we report in @Nature the characterization of Fanzor, a eukaryotic RNA-guided system that can be reprogrammed for human genome editing. https://t.co/aKLMMEBRkk
A new report in @NEJM from Waseem Qasim and coworkers describes the clinical outcomes of the first three T-cell leukemia patients treated with triply base-edited CAR-T cells in the first clinical trial of a base edited therapeutic, conducted at Great Ormond Street Hospital in the UK.

🚨We have published a paper in @NatureBiotech!
Find out more about the development of a #CRISPR-therapeutic to eradicate E. coli in hematological #cancer patients, potentially preventing fatal infections.

Today we report in @NatureBiotech the development of dual-AAV in vivo delivery systems for prime editors that can support efficient prime editing in multiple organs such as brain, liver, and heart.

Congrats to See and @Yongsub__Kim on publishing their protocol on analyzing BRCA1 variants using Base Editors.
Thanks for using #crispresso2! https://t.co/5aVDxy93d7
