Macrophage fatty acid oxidation in atherosclerosis.

Atherosclerosis significantly contributes to the development of cardiovascular diseases (CVD) and is characterized by lipid retention and inflammation within the artery wall. Multiple immune cell types are implicated in the pathogenesis of atherosclerosis, macrophages play a central role as the primary source of inflammatory effectors in this pathogenic process. The metabolic influences of lipids on macrophage function and fatty acid β-oxidation (FAO) have similarly drawn attention due to its relevance as an immunometabolic hub.

LncRNA MIAT knockdown alleviates oxygen-glucose deprivation‑induced cardiomyocyte injury by regulating JAK2/STAT3 pathway via miR-181a-5p.

Background: Coronary artery disease (CAD) is a common heart disease with high incidence and mortality. Myocardial ischemia is the main type of CAD, which negatively affects health worldwide. The aim of the present study was to investigate the function and mechanism of myocardial infarction-associated transcript (MIAT) in myocardial ischemia.

Antioxidant defence system is responsible for the toxicological interactions of mixtures: A case study on PFOS and PFOA in Daphnia magna.

Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) are two types of perfluorinated compounds (PFCs) frequently studied in recent years due to their potential for bioaccumulation and toxicity to humans. Usually, PFCs can co-exist in various environment. Therefore, over- or under-estimated risk assessments would result if antagonism or synergism occurred in mixture toxicity.

NFATc4 and myocardin synergistically up-regulate the expression of LTCC α1C in ET-1-induced cardiomyocyte hypertrophy.

Aims: Dysregulation of Ca(2+) is a central cause of cardiac hypertrophy. The α1C subunit of L-type Ca(2+) channel (LTCC) is a pore-forming protein which is responsible for the voltage-dependent channel gating and channel selectivity for Ca(2+). Myocardin and nuclear factor of activated T-cells c4 (NFATc4) are two key transcription factors in cardiac hypertrophy.

MicroRNA-29a-3p attenuates ET-1-induced hypertrophic responses in H9c2 cardiomyocytes.

Transcription factor nuclear factor of activated T cells c4 (NFATc4) is the best-characterized target for the development of cardiac hypertrophy. Aberrant microRNA-29 (miR-29) expression is involved in the development of cardiac fibrosis and congestive heart failure. However, whether miR-29 regulates hypertrophic processes is still not clear.

Protein kinase Cα inhibits myocardin-induced cardiomyocyte hypertrophy through the promotion of myocardin phosphorylation.

Myocardin plays a key role in the development of cardiac hypertrophy. However, the upstream signals that control the stability and transactivity of myocardin remain to be fully understood. The expression of protein kinase Cα (PKCα) also induces cardiac hypertrophy.

Ca²⁺ signal-induced cardiomyocyte hypertrophy through activation of myocardin.

Hypertrophic growth of cardiomyocytes in response to pressure overload is an important stage during the development of many cardiac diseases. Ca(2+) overload as well as subsequent activation of Ca(2+) signaling pathways has been reported to induce cardiac hypertrophy. Myocardin, a transcription cofactor of serum response factor (SRF), is a key transducer of hypertrophic signals.
