Abstract
Myocardial infarction (MI), a prevalent cardiovascular disease, is fundamentally precipitated by thrombus formation in the coronary arteries, which subsequently decreases myocardial perfusion and leads to cellular necrosis. The intricacy of MI pathogenesis necessitates extensive research to elucidate the disease's root cause, thereby addressing the limitations present in its diagnosis and prognosis. With the continuous advancement of genomics technology, genomics, proteomics, metabolomics and transcriptomics are widely used in the study of MI, which provides an excellent way to identify new biomarkers that elucidate the complex mechanisms of MI. This paper provides a detailed review of various genomics studies of MI, including genomics, proteomics, transcriptomics, metabolomics and multi-omics studies. The metabolites and proteins involved in the pathogenesis of MI are investigated through integrated protein-protein interactions and multi-omics analysis by STRING and Metascape platforms. In conclusion, the future of omics research in myocardial infarction offers significant promise.

Biochem Biophys Res Commun 2019; 514:280-286. [PMID: 31030942 DOI: 10.1016/j.bbrc.2019.04.128] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2019] [Accepted: 04/18/2019] [Indexed: 12/14/2022]
Abstract
NADPH oxidase (Nox) is the main source of reactive oxygen species in vascular diseases, which have been implicated in promoting VSMCs phenotypic switch. P22phox, the indispensable component of the complex Nox, is required for their activity and stability. Krüppel-like factor 4 (KLF4) is an important transcriptional regulator of VSMCs phenotypic switch. Both KLF4 and p22phox are involved in the proliferation, migration and differentiation of VSMC. This study aims to determine whether and how p22phox regulates KLF4 expression in phenotypic switching of VSMCs. In cultured primary rat VSMCs, we noticed that the expression of P22phox was significantly increased in combination with VSMCs phenotypic switch and up-regulated KLF4 expression in Ang-II-treated cells. Ang-II-induced VSMC dedifferentiation, proliferation, migration, KLF4 expression, H2O2 production and the phosphorylation of AKT, ERK1/2 were all inhibited by knockdown of P22phox. Furthermore, H2O2 treatment effectively enhanced the phosphorylation of AKT, ERK1/2 and the expression of KLF4, whereas LY294002 (a specific inhibitor of PI3K), U0126 (a specific inhibitor of ERK1/2) significantly attenuated the H2O2-induced up-regulation of KLF4. In conclusion, these results demonstrated that p22phox promotes Ang-II-induced VSMC phenotypic switch via the H2O2-ERK1/2/AKT-KLF4 signaling pathway.
