Integrative transcriptomic analysis of tissue-specific metabolic crosstalk after myocardial infarction


ABSTRACT: Purpose: Myocardial infarction (MI) promotes a range of systemic effects, many of which are unknown. Here, we investigated the alterations associated with MI progression in heart and other metabolically active tissues (liver, skeletal muscle, and adipose) in a mouse model of MI (induced by ligating the left ascending coronary artery) and sham-operated mice. Results: By generating tissue-specific biological networks, we observed: (1) dysregulation in multiple biological processes (including immune system, mitochondrial dysfunction, fatty-acid beta-oxidation, and RNA and protein processing) across multiple tissues post MI; and (2) tissue-specific dysregulation in biological processes in liver and heart post MI. Conclusions: Overall, our integrative analysis highlighted both common and specific biological responses to MI across a range of metabolically active tissues.
