Neanderthal DNA reveals how human faces form Subtle genomic variations between humans and Neanderthals provide clues to how DNA shapes our facial features.

Researchers have identified gene-regulatory variants that might have contributed to Neanderthals’ beefy jaws β€” offering a window on how the human face developed

We suggest that increased activity of the Neanderthal EC1.45 regulatory element may have impacted SOX9 expression during development to shape lower jaw morphology.

More details in the paper - including overexpression of SOX9 in EC1.45-active cells and single cell RNA-seq to define key cell types.

We observed that the Neanderthal EC1.45 enhancer was more active than the human enhancer in a region of the developing face adjacent to the forming lower jaw.

Quantitative spatial and temporal assessment of regulatory element activity in zebrafish A new method for quantitative assessment of altered regulatory potential of human enhancers bearing disease-associated mutations using live imaging in zebrafish embryos.

To explore the impact of these genetic differences on gene regulatory activity, we leveraged a dual fluorescent reporter assay in zebrafish called Q-STARZ that enables live imaging of regulatory activity for two enhancers concurrently during development.

To explore this question, we turned to recent human evolution and single nucleotide changes in EC1.45 which are found uniquely in the Neanderthal genome. From looking at the fossil record, Neanderthal jaws were very distinct to our own. Could changes in EC1.45 perhaps contribute to this difference?

One of these enhancers (EC1.45) lies a huge 1.45 megabases upstream of the SOX9 gene, yet is crucial for its expression during facial formation. We reasoned that smaller genetic changes within EC1.45 may tweak its activity and cause more subtle impacts to facial shape.

In our previous work, we explored how chromosomal translocations and large deletions upstream of the SOX9 gene may impact facial development in patients with Pierre Robin sequence (PRS). We identified two candidate enhancers active in facial progenitor cells.

We recently reported that promoter competition can contribute to the robust insulation of gene regulatory domains (www.nature.com/articles/s41...).
We now offer a 4-years PhD contract to investigate whether the dirsuption of this regulatory mechanism can lead to congenital defects. More details πŸ‘‡
