Figure Lengend Snippet: (A) Graph shows the mean fold change (percentage) of mRNA expression of 43 GT families in pancreatic cancer cells (PANC-1, MIA PaCa-2, Capan-2) after 3 hours of interaction of cancer cells with platelets compared to before their interaction (control). Colors represent an overexpression of at least 150% (red), 100% (pink), 50% (purple) or less than 50% (blue) of the mRNA of GT families in cancer cells after platelet interaction or, conversely, an underexpression of at least 25% (red), 15% (pink), 10% (purple) or less than 10% (blue). Data were normalized to the housekeeping gene HPRT1 and histogram represents the mean of three independent experiments (ANOVA test, ****P < 0.0001, * P = 0.0401). (B) Representative images and corresponding quantification of glycan motif detection using 4 lectins: VVL/VVA, (left upper panel) AAL (right upper panel), ConA (left lower panel), PHA-E (right lower panel) by Western Blot of pancreatic cancer cell lysates (PANC-1, MIA PaCa-2 or Capan-2, 40 µg) interacting (+) or not (−) with platelets for 3 hours. GAPDH expression was detected as a loading control for the experiment. The graphs show the mean of integrated density (+/− SEM) of glycan motif expression normalized to cancer cells alone (t-test, **P = 0.0086, * P = 0.0240, ns = not significant). (C) The graph represents the mean fold change (percentage) of mRNA expression of 124 genes encoding proteins involved in inflammation and metastasis in a human colorectal cancer cell line (HT-29) after 3 hours of interaction with platelets compared to before their interaction. Colors represent an overexpression of at least 300% (red), 200% (pink), 100% (purple) or less than 100% (blue) of the mRNA in platelet-educated cancer cells. Data were normalized to the housekeeping gene HPRT1. (D) Protein-protein interaction network using STRING database 12.0. Only the 38 genes with at least an 100% overexpression were considered to perform this analysis. Nodes represent proteins and each node color (red, yellow, dark blue, light blue or green) indicates a gene cluster. Edges represent known interactions from the curated database (light blue) or experimentally determined (pink); scientific literature (yellow/green); co-expression (black) or protein homology (dark blue). (E) Representative image of fibronectin (FN1, 273 kDa, left panel) detection by Western Blot in 15 µg of PANCO2 cell lysates 6, 24 or 48 hours after their interaction with platelets (+) or not (−). GAPDH expression was detected as a loading control. The histogram (down panel) presents the relative quantification of the FN1/GAPDH ratio in PANCO2 cells + platelets, normalized to PANCO2 cells alone, over time up to 48 hours.

Figure Lengend Snippet: Increased uptake of PC-3AcT EVs and regulated proteins related to their uptake by PC-3 cells. A , far red –labeled EVs at 2.0 × 10 9 particles/ml were used to treat PC-3 cells and their taken fluorescent EVs were measured by fluorescence microscope. PC-3AcT EVs showed better uptake than PC-3 EVs in PC-3 cells. Please note that fluorescent spots that exceed 1 μm represent clusters of labeled EV-derived components or aggregates in cellular compartments ( e.g. , endosomes or lysosomes). B , differentially regulated EV proteins were mapped in KEGG ECM–receptor interaction annotation. Collagen COLA1, FN1, and other ECMs were overexpressed in PC-3AcT EVs. C , protein–protein interaction network among 1.5-fold upregulated PC-3AcT EV proteins was mapped in the BioGRID protein interaction database and their interactions were visualized by Cytoscape ( cytoscape.org ). EV proteins were grouped based on their main functionality and related proteins as indicated by a dashed line box. p -values (∗∗∗∗ < 0.0001).
