Bidirectional cell-cell communication involving exosome-borne cargo such as miRNA has emerged a critical mechanism for wound healing. Unlike other shedding vesicles, exosomes selectively package by SUMOylation of heterogeneous nuclear ribonucleoproteinA2B1 (hnRNPA2B1). In this work, we elucidate the significance exosome in keratinocyte-macrophage crosstalk following injury. Keratinocyte-derived were genetically labeled with GFP-reporter (Exoκ-GFP) using tissue nanotransfection (TNT), and...
The tumor microenvironment in pancreatic ductal adenocarcinoma (PDAC) plays a key role progression and response to therapy. dense PDAC stroma causes hypovascularity, which leads hypoxia. Here, we showed that hypoxia drives long-lasting epithelial-mesenchymal transition (EMT) primarily through positive-feedback histone methylation-MAPK signaling axis. Transformed cells preferentially underwent EMT hypoxic regions multiple model systems. Hypoxia drove cell autonomous cells, which, unlike...
ABSTRACT Epithelial-mesenchymal transition (EMT) occurs heterogeneously among malignant carcinoma cells to promote chemoresistance. Identifying the signaling pathways involved will nominate drug combinations chemoresponse, but cell population-level studies are inherently fraught, and single-cell transcriptomics limited indirect ontology-based inferences. To understand EMT heterogeneity at a protein level, we combined iterative immunofluorescence imaging of pancreas cancer tumors mutual...
The masses of particles in a bovine milk extracellular vesicle (EV) preparation enriched for exosomes were directly determined the first time by charge detection mass spectrometry (CDMS). In CDMS, both mass-to-charge ratio (m/z) and z are simultaneously individual particles, enabling determinations that far beyond limit (∼1.0 MDa) conventional (MS). Particle charges span wide range from m ∼ 2 to ∼90 MDa 50 ∼1300 e (elementary charges) highly dependent upon conditions used extract isolate...

Unresolved inflammation compromises diabetic wound healing. Recently, we reported that inadequate RNA packaging in murine wound-edge keratinocyte-originated exosomes (Exoκ) leads to persistent [Zhou, X. ACS Nano 2020, 14(10), 12732−12748]. Herein, use charge detection mass spectrometry (CDMS) analyze intact Exoκ isolated from a 5 day old tissue of mice and heterozygous nondiabetic littermate control group. In CDMS, the (z) mass-to-charge ratio (m/z) individual exosome particles are measured...
