This highly innovative in-vivo cell-tracking tool uses nanobody-based PET imaging to track unmodified transplanted cells in immunocompetent mice and avoids bulky antibodies or genetic engineering.

This is why Israel refuses to allow the international press access to Gaza.
Because images like this make it impossible to deny that this is genocide.

In vivo prime editing rescues alternating hemiplegia of childhood in mice Prime editing and base editing in mouse models and human cells effectively correct mutations in a gene that causes a childhood neurodevelopmental disorder called alternating hemiplegia of childhood. In vivo prime editing in the brain results in significant improvements in neurological symptoms and lifespan, highlighting a potential one-time gene therapy approach for the disorder.

GitHub - vierstralab/hotspot3: A chromatin accessibility peak caller with an adaptive background model A chromatin accessibility peak caller with an adaptive background model - vierstralab/hotspot3

We have created a new DNase I- & ATAC-seq peak caller that uses an adaptive background model that controls for copy number variation & aneuploidy. It performs a per-nucleotide test (+FDR correction) and is very fast. Please try it out and give us feedback!

Vostok: A looping factor for the organization of the regulatory genome in the Drosophila brain In Drosophila, tethering elements are DNA regulatory regions that facilitate long-range interactions between enhancers and promoters as well as between the promoters of distant paralogous genes. Hu et al. demonstrate that the Vostok protein binds to these elements in the larval brain and is essential for the correct expression of associated genes.

Powerful CRISPR system inserts whole gene into human DNA β€˜Directed’ evolution in the laboratory creates an editing tool that outperforms classic CRISPR systems.

🧬 CRISPR just levelled up

A new tool, evoCAST, can insert entire genes into human DNA, with no cutting required.

Hopefully this is one step closer to safe, scalable gene therapies.
