Cardiomyocyte-specific CYP2J2 and its therapeutic implications

Introduction Cytochrome P450s (CYPs) are a superfamily of monooxygenases with diverse biological roles. CYP2J2 is an isozyme highly expressed in the heart where it metabolizes endogenous substrates such as N-3/N-6 polyunsaturated fatty acids (PUFA) to produce lipid mediators involved in homeostasis and cardioprotective responses. Expanding our knowledge of the role CYP2J2 has within the heart is important for understanding its impact on cardiac health and disease. Areas covered The objective of this review was to assess the state of knowledge regarding cardiac CYP2J2. A literature search was conducted using PubMed-MEDLINE (from 2022 and earlier) to evaluate relevant studies regarding CYP2J2-mediated cardioprotection, small molecule modulators, effects of CYP2J2 substrates toward biologically relevant effects and implications of CYP2J2 polymorphisms and sexual dimorphism in the heart. Expert opinion Cardiac CYP2J2-mediated metabolism of endogenous and exogenous substrates have been shown to impact cardiac function. Identifying individual factors, like sex and age, that affect CYP2J2 require further elucidation to better understand CYP2J2MODIFIER LETTER PRIMEs clinical relevance. Resolving the biological targets and activities of CYP2J2-derived PUFA metabolites will be necessary to safely target CYP2J2 and design novel analogues. Targeting CYP2J2 for therapeutic aims offers a potential novel approach to regulating cardiac homeostasis, drug metabolism and cardioprotection.

Automated summary

Cytochrome P450s (CYPs) are a superfamily of monooxygenases with diverse biological roles. CYP2J2, highly expressed in the heart, plays a crucial role in metabolizing fatty acids to produce lipid mediators involved in cardiac homeostasis and protection. Understanding the function and impact of CYP2J2 in the heart is important for cardiac health and disease. This review examines the current knowledge on cardiac CYP2J2, including its role in cardioprotection, small molecule modulators, effects of CYP2J2 substrates, and implications of CYP2J2 polymorphisms and sexual dimorphism. Further research is needed to elucidate the clinical relevance of individual factors and identify the targets and activities of CYP2J2-derived metabolites.
