A very nice highlight of our recent paper!
Check out the🧵below on the latest pre-print from @eliasfriman.bsky.social I am really glad to have had the opportunity to contribute to this exciting project! ✨
Find out how the dark genome holds clues to Neanderthal face shape and how this could help in future research into human disease in this new study from IGC researchers 👉 edin.ac/443d1j4 @hannahlong.bsky.social @kirstyuttley.bsky.social @hannahjuellig.bsky.social @cmvm-edinburghuni.bsky.social

To learn more about how this story developed and the researchers behind it, we talked to co-first authors Kirsty Uttley and Hannah Jüllig, as well as corresponding author, Hannah Long doi.org/10.1242/dev....
Neanderthal DNA enhances our understanding of face development This Research Highlight showcases the work from Hannah Long @hannahlong.bsky.social, Kirsty Uttley @kirstyuttley.bsky.social, Hannah Jüllig @hannahjuellig.bsky.social and colleagues: journals.biologists.com/dev/article/...
Although cohesin-sensitive, long-range enhancer activation is equivalent in nature to proximal activation. Cooperativity can arise from different levels of activation inputs operating on a non-linear response function. @eliasfriman.bsky.social @uoe-igc.bsky.social www.biorxiv.org/content/10.6...

Excited to share my first preprint from my PhD w/ @justinmcrocker.bsky.social. We show that cell type-specific regulatory dominance promotes robustness and evolutionary innovation through interallelic transcriptional hubs, potentially expanding the mutational paths available to diploids. (1/18)

Researchers have identified gene-regulatory variants that might have contributed to Neanderthals’ beefy jaws — offering a window on how the human face developed go.nature.com/3Ke6StJ

Is distal gene activation by enhancers inherently different from promoter-proximal activation? We propose not. But both cohesin and cooperativity are important aspects of how transcription is affected. Happy to share our recent preprint (thread below) 1/ www.biorxiv.org/content/10.6...

Differences in a specific region of the Neanderthal genetic code may have contributed to their distinctive protruding jawline, a study suggests.

Facial development is highly sensitive to genetic and environmental perturbation, with craniofacial malformation associated with over one-third of congenital birth defects. The face arises during an early and largely inaccessible window of embryonic development, with a large contribution from transient and multipotent cranial neural crest cells (CNCCs). Assessment of the molecular and cellular mechanisms driving normal and disordered human facial development therefore relies greatly on the use of in vitro cellular models. Here, we adapted a neurosphere-based CNCC differentiation protocol to facilitate robust quantification of early specification and migration events. Introduction of single-cell aggregation with arrayed plating enabled standardisation of neurosphere size, growth and patterning. Inclusion of fibronectin coating enhanced the efficiency of neurosphere attachment and synchronicity of CNCC migration timing. To demonstrate application of the Array-CNCC method, we developed a strategy for mosaic co-culture, which can facilitate differentiation of wildtype untreated cells directly alongside cells exposed to distinct drug treatments or genetic alterations. Finally, we present a screening approach which we use to test the impact of distinct extracellular matrix components on neurosphere morphology, CNCC migration and gene expression. Together, the Array-CNCC method is highly amenable to quantitative phenotyping and screening approaches, enabling enhanced craniofacial disease modelling with both cellular and molecular readouts. ### Competing Interest Statement The authors have declared no competing interest.
