Observational analysis identifies COX7A as a regulator of mitochondrial integrity and ploidy in cardiomyocytes, suggesting dual roles in differing tissues.
Key Points
Disruption of cellular coordination in polyploid cells can lead to birth defects and diseases.
COX7A plays opposing roles in heart and salivary gland tissues, affecting mitochondrial integrity and ploidy.
Through human-fly screening, COX7A was identified as a unique regulator of cardiac growth and ploidy control.
Findings highlight critical cross-talk between mitochondrial biogenesis and genome duplication in organ growth.
