Ever wonder what the #3Dgenome folding🔺of a Neanderthal looked like?! Could it hold any clues as to where and why we have DNA 🧬and trait differences?

Sadly, bc of ancient👴sample degradation, we've never explored the role of the 3D genome in archaic hominins like Neanderthals/Denisovans.
But lucky for us, new deep learning models can infer 3D genome structure from DNA sequence alone (like @gfudenberg & @drklly's Akita).

Using these models, we predict 3D contact maps across Neanderthal, Denisovan, and diverse modern human genomes.
We identify 167 distinct regions with diverged 3D genome organization between archaics and modern humans across the genome!

Thrilled to share our latest work, now in @ScienceMagazine! Exploring how #3DGenome organization controls #transcription dynamics during #development. A few highlights below! #InHoxWeTrust

The Drosophila genome is organized by 2 types of elements: tethers mediate focal contacts, while insulators establish #TAD boundaries. We used genome editing and live transcription imaging to explore their roles in the temporal regulation of #Hox gene expression in the embryo.
Transcription of the endogenous Scr gene, live! Active transcription foci (white spots) appear in a narrow stripe of nuclei (blue) just prior to the onset of gastrulation. (Scr-MS2, MCP-GFP, His2A-RFP)
Excited to present my first @capra_lab PhD project in today's @GeneticsSociety's @AJHGNews!!

By synthesizing topologically associating domain (TAD) maps across 37 diverse cell types with 41 genome-wide association studies (GWASs), we investigate the differences in disease association and evolutionary pressure on variation across the 3D genome landscape.

We know that TAD boundary disruption by SV can lead to developmental disease and cancers. (Thus, selection acts against these SVs).Â
But what about the relationship between common human variation in TAD boundaries (eg. SNPs) and associations with complex traits?

(1/6) Excited to share that our OligoFISSEQ paper is up (nature.com/articles/s4159…)! We set out to develop single cell in situ #3Dgenome mapping methods. A fun collaborative effort led by @huy_sauce @ShyamtanuC and David Castillo, from @TingWu_Lab and @mamartirenom groups.
(2/6) An idea that began with @SonCNguyen and Evan Daugharthy. The rest of the team including: @GuyNir5 @AntoniosLioutas @ElliotHershberg @Nuno_MCMartins @PaulReginato Mohammed Hannan @oligopain and @geochurch . Shout out to everyone @naturemethods for the great experience!
(3/6) To target and visualize genomic regions at genome-wide scale, we barcoded Oligopaints, increasing target capacity exponentially. We then visualize and map the targets by #InSituSequencing the barcodes using hybridization, synthesis, and ligation-based approaches.
