Article Abstract
Background: Among various bio-informative molecules transferred by exosomes between cells, micro RNAs (miRNAs), which remain remarkably stable even after freeze-and-thaw cycles, are excellent candidates for potential biomarkers for coronary artery disease (CAD).
Methods: Blood samples were collected from the coronary arteries of 214 patients diagnosed with three-vessel CAD and 140 without CAD. After precipitation extraction, the amounts of exosomes were found to decrease with increased age and three-vessel CAD. Next-generation sequencing was performed to further explore the possible relationship between exosomal miRNAs and CAD.
Results: Eight exosomal miRNAs showed altered expression associated with CAD. The up-regulated miRNAs in CAD were miRNA-382-3p, miRNA-432-5p, miRNA-200a-3p, and miRNA-3613-3p. The down-regulated miRNAs were miRNA-125a-5p, miRNA-185-5p, miRNA-151a-3p, and miRNA-328-3p.
Conclusion: We successfully demonstrated particular exosomal miRNAs that may serve as future biomarkers for CAD.

Oligomeric proanthocyanidins (OPCs), condensed tannins found plentiful in grape seeds and berries, have higher bioavailability and therapeutic benefits due to their low degree of polymerization. Recent evidence places OPCs as effective modulators of cancer stem cell (CSC) plasticity and tumor growth. Mechanistically, OPCs orchestrate multi-pathway inhibition by destabilizing Wnt/β-catenin, Notch, PI3K/Akt/mTOR, JAK/STAT3, and Hedgehog pathways, triggering β-catenin degradation, silencing stemness regulators (OCT4, NANOG, SOX2), and stimulating tumor-suppressive microRNAs (miR-200, miR-34a).

Introduction: Mutations in SORL1, encoding the sorting receptor Sortilin-related receptor with A-type repeats (SORLA), are found in individuals with Alzheimer's disease (AD). We studied SORLA, carrying a mutation in its ligand binding domain, to learn more about receptor functions relevant for human brain health.
Methods: We investigated consequences of SORLA expression in induced pluripotent stem cell (iPSC)-derived human neurons and microglia, using unbiased proteome screens and functional cell assays.

Objective: Long-term administration of dexamethasone (DEX) to treat severe inflammation or autoimmune disorders often result in skeletal muscle atrophy and functional decline. Exosomes facilitate intercellular communication by transferring bioactive molecules, reflecting the characteristics of their tissue of origin. Myostatin-knockout (MSTN) mice exhibit muscle hypertrophy, and their muscle-derived exosomes (KO-EXOs) retain this phenotype.

Exosomes derived from various cells have been demonstrated to contribute to cardiac repair by regulating macrophage polarization in myocardial infarction. However, how exosomes secreted from cardiomyocytes under hypoxia-ischemia (Hypo-Exo) regulate macrophage polarization in the local tissues is elusive. This study aimed to determine the underlying mechanisms by which Hypo-Exo polarized M2 macrophages.

Liver cancer, particularly hepatocellular carcinoma (HCC), poses significant treatment challenges due to chemoresistance and cancer recurrence. Similar to customs at the border, the liver detoxifies incoming chemicals via efflux pumps and overexpresses ATP-binding cassette (ABC) drug exporters, leading to chemoresistance. ABC contains a multihomosubunit structure and a revolving transport mechanism, actively effluxing drugs from cancer cells, thereby reducing intracellular drug accumulation and therapeutic efficacy.
