ÅNGSTRÖM-RESOLUTION IMAGING OF CELL-SURFACE GLYCANS 🧬🎨🍬

The glycocalyx, our cells' sugar coat, holds secrets in immunology, cancer, viral infections, and more. Visualizing its molecular architecture was impossible… until now. #glycotime #microscopy

Our latest work: how can compartmentalization emerge in a eukaryotic genome lacking canonical heterochromatin?
By investigating bacterial genomes put in yeast, we show that the presence or absence of transcription is sufficient!

Sequence-dependent activity and compartmentalization of foreign DNA in a eukaryotic nucleus
In eukaryotes, DNA-associated protein complexes coevolve with genomic sequences to orchestrate chromatin folding. We investigate the relationship between DNA sequence and the spontaneous loading and a...

Randomizing the human genome by engineering recombination between repeat elements
We lack tools to edit DNA sequences at scales necessary to study 99% of the human genome that is noncoding. To address this gap, we applied CRISPR prime editing to insert recombination handles into re...

We are happy to share our enhancer scramble story, a strategy to create hundreds of stochastic deletions, inversions, and duplications within mammalian gene regulatory regions and associate these new architectures with gene expression levels 🧵
