Mitochondria in the human heart

H Lemieux, CL Hoppel - Journal of bioenergetics and biomembranes, 2009 - Springer
The heart relies mainly on mitochondrial metabolism to provide the energy needed for
pumping blood to oxygenate the organs of the body. The study of mitochondrial function in the …

Altered mitochondrial metabolism in the insulin‐resistant heart

…, E Liepinsh, AJ Murray, H Lemieux… - Acta …, 2020 - Wiley Online Library
Obesity‐induced insulin resistance and type 2 diabetes mellitus can ultimately result in
various complications, including diabetic cardiomyopathy. In this case, cardiac dysfunction is …

Deficiency or inhibition of oxygen sensor Phd1 induces hypoxia tolerance by reprogramming basal metabolism

…, M Mazzone, R Dirkx, S Zacchigna, H Lemieux… - Nature …, 2008 - nature.com
HIF prolyl hydroxylases (PHD1–3) are oxygen sensors that regulate the stability of the
hypoxia-inducible factors (HIFs) in an oxygen-dependent manner. Here, we show that loss of …

Mitochondria in the elderly: is acetylcarnitine a rejuvenator?

MG Rosca, H Lemieux, CL Hoppel - Advanced drug delivery reviews, 2009 - Elsevier
Endogenous acetylcarnitine is an indicator of acetyl-CoA synthesized by multiple metabolic
pathways involving carbohydrates, amino acids, fatty acids, sterols, and ketone bodies, and …

Do digestive enzymes set a physiological limit on growth rate and food conversion efficiency in the Atlantic cod (Gadus morhua)?

H Lemieux, P Blier, JD Dutil - Fish Physiology and Biochemistry, 1999 - Springer
The objective of this study was to determine the potential sites of maximal growth limitation
in Atlantic cod (Gadus morhua). Forty cod were reared in ten sea water tanks. Fish were …

Mitochondrial respiratory control and early defects of oxidative phosphorylation in the failing human heart

H Lemieux, S Semsroth, H Antretter, D Höfer… - The international journal …, 2011 - Elsevier
Heart failure is a consequence of progressive deterioration of cardiac performance. Little is
