We’re celebrating our Research Fellow, Dr. Alex Chan, on the successful publication of his latest paper:
“Distinct profiles of mitochondrial bioenergetics and redox balance in left atrial and ventricular myocardium in the healthy rat heart.” 💙🐀
🔍 What was this study about?
Mitochondria live inside our cells and turn oxygen and sugar into usable energy - a process called respiration. In doing so, they also release various byproducts.
This study explored how those mitochondrial outputs differ between two chambers of the heart: the left atrium (upper chamber) and the left ventricle (lower chamber) in healthy rat hearts.
✨ What did the team discover?
The left ventricle showed a higher mitochondrial respiratory capacity per tissue mass, but lower function when adjusted for mitochondrial content compared with the left atrium.
These chamber-specific differences highlight why it’s so important to study each region of the heart separately when trying to understand both healthy function and disease.
We are incredibly proud of you, Alex! 💙
