With the deepening of research, proteomics has developed into a science covering the study of all the structural and functional characteristics of proteins and the dynamic change rules. The essence of various biological activities is revealed from the perspectives of the biological structure, functional activity and corresponding regulatory mechanism of proteins by proteomics. Among them, phospholipid-binding protein is one of the hotspots of proteomics, especially annexin A1, which is widely present in various tissues and cells of the body. It has the capability of binding to phospholipid membranes reversibly in a calcium ion dependent manner. In order to provide possible research ideas for researchers, who are interested in this protein, the biological effects of annexin A1, such as inflammatory regulation, cell signal transduction, cell proliferation, differentiation and apoptosis are described in this paper.

Annexins are a family of calcium-dependent phospholipid-binding proteins involved in crucial cellular processes such as cell division, calcium signaling, vesicle trafficking, membrane repair, and apoptosis. In addition to these properties, Annexins have also been shown to bind RNA, although this function is not universally recognized. In the attempt to clarify this important issue, we employed an integrated combination of experimental and computational approaches.

Background: Findings have demonstrated that mitochondrial dysfunction is vital to Alzheimer's Disease (AD) pathogenesis and progression. This study explored an innovative treatment strategy involving transfer of polymer-functionalized, healthy mitochondria to AD neurons. We hypothesized that this organelle transplantation approach would restore mitochondrial function and bioenergetics, preventing aberrant neuronal dynamics associated with AD.

Ischemic stroke is a prevalent clinical condition that poses a significant global challenge. Developing innovative strategies to address this issue is crucial. Annexin A1 (ANXA1), a key member of the annexin superfamily, performs various functions, such as inhibiting inflammatory factor release, promoting phagocytosis, and blocking leukocyte migration.

Background: Curcumin (Cur) is a polyphenol phyto-compound found in turmeric () that inhibits tumorigenesis by introducing apoptosis and restricting cell survival and proliferation. This in vitro research article focuses on the pharmacodynamic interactions of Cur combined with the commercial drug doxorubicin (Doxo) to enhance the cytotoxicity of Doxo at lower doses against triple-negative breast cancer cells (MDA-MB-231) with the chemo-protective effect against normal HEK293 cells. In this study, we observed the dose-dependent cytotoxicity, increased reactive oxygen species (ROS) generation, and increased chromatin condensation in combination doses compared to single doses.

Introduction: Proton pump inhibitors (PPIs) and potassium-competitive acid blockers (P-CABs) are widely used to manage gastric acid-related disorders by inhibiting hydrochloric acid (HCl) secretion from parietal cells in the stomach. Although PPIs are known to have anti-inflammatory properties beyond their role in inhibiting gastric acid secretion, research on P-CABs is lacking. In this study, we aimed to investigate whether all available P-CABs exhibit anti-inflammatory effects in gastroesophageal reflux-induced esophagitis and to elucidate the underlying mechanisms.
