Implication

Experimental study reveals that HMGCR disruption causes jaw defects through chondrocyte shrinkage and apoptosis in zebrafish embryos, highlighting its essential role in craniofacial development.

Key Points

To identify the cellular and morphogenetic mechanisms by which HMGCR deficiency causes craniofacial malformations and orofacial clefting.
Examined chondrocyte dimensions, counts, and lower jaw morphology in hmgcr1b mutant and atorvastatin-treated zebrafish embryos.
Quantified cell proliferation and apoptosis within the ethmoid plate using confocal microscopy with maximum intensity z-projections.
Ceratohyal shortening was caused by a moderate reduction in cell count coupled with isometric shrinkage of chondrocytes.
Ethmoid plate shortening was driven by slightly decreased cell proliferation alongside massive abnormal apoptosis localized at the proliferation front.
