AI Article Synopsis

  • - Cardiovascular disease (CVD) is the leading cause of death worldwide, with atherosclerosis being its main underlying cause; understanding how various risk factors contribute to atherosclerosis is crucial for developing effective treatments.
  • - Recent research highlights the significance of endoplasmic reticulum (ER) stress throughout the atherosclerotic process, specifically its impact on macrophages, which are immune cells involved in inflammation and lipid accumulation.
  • - The article focuses on the ER stress signaling pathway via glycogen synthase kinase (GSK)-3α, detailing its role in macrophage behavior and the potential for targeting this pathway in new atherosclerosis therapies.

Article Abstract

Cardiovascular disease (CVD) is the number one cause of global mortality and atherosclerosis is the underlying cause of most CVD. However, the molecular mechanisms by which cardiovascular risk factors promote the development of atherosclerosis are not well understood. The development of new efficient therapies to directly block or slow disease progression will require a better understanding of these mechanisms. Accumulating evidence supports a role for endoplasmic reticulum (ER) stress in all stages of the developing atherosclerotic lesion however, it was not clear how ER stress may contribute to disease progression. Recent findings have shown that ER stress signaling through glycogen synthase kinase (GSK)-3α may significantly contribute to macrophage lipid accumulation, inflammatory cytokine production and M1macrophage polarization. In this review we summarize our knowledge of the potential role of ER stress-GSK3 signaling in the development and progression of atherosclerosis as well as the possible therapeutic implications of this pathway.

Growth differentiation factor 15 (GDF15) can be induced under various stress conditions. This study aimed to explore the role of GDF15 in oxygen-glucose deprivation/reoxygenation (OGD/R)-induced HT22 cells. OGD/R was employed to induce the HT22 cell model, and GDF15 expression was upregulated via transfection.

Mucociliary clearance (MCC) is a host defense mechanism of the respiratory system. Beating cilia plays a crucial role in the MCC process and ciliary beat frequency (CBF) is activated by several factors including elevations of the intracellular cAMP concentration ([cAMP]), intracellular Ca concentration ([Ca]), and intracellular pH (pH). In this study, we investigated whether an artichoke-extracted component cynaropicrin could be a beneficial compound for improving MCC.

Myocardial ischemia-reperfusion (I/R) injury represents a significant clinical challenge with limited therapeutic options. Single-cell RNA sequencing and bioinformatics analyses have revealed complex cellular interactions within cardiac tissue, highlighting the crucial role of cardiomyocytes in intercellular communication. During I/R injury, cardiomyocytes experience severe endoplasmic reticulum (ER) stress, leading to detrimental intercellular communication that affects surrounding cells, particularly promoting the transformation of macrophages toward a pro-inflammatory phenotype.

Reactive oxygen species (ROS) are crucial in stress perception, the integration of environmental signals, and the activation of downstream response networks. This review emphasizes ROS-mediated signaling pathways in microalgae and presents an overview of strategies for leveraging ROS. Eight distinct signaling pathways mediated by ROS in microalgae have been summarized, including the calcium signaling pathway, the target of rapamycin signaling pathway, the mitogen-activated protein kinase signaling pathway, the cyclic adenosine monophosphate/protein kinase A signaling pathway, the ubiquitin/protease pathway, the ROS-regulated transcription factors and enzymes, the endoplasmic reticulum stress, and the retrograde ROS signaling.

Electronic address:

Salivary adenoid cystic carcinoma (SACC) tends to metastasize to the lungs in the early stages of the disease. Factors secreted by the primary tumor can induce the formation of a supportive microenvironment in distant organs prior to metastasis, a process known as pre-metastatic niche (PMN) formation. Extracellular vesicles (EVs) participate in PMN formation.
