(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.

(C) Representative images of three independent experiments of PANCO2 mock or PANCO2 low FN1 cells over time up to 24 hours (holotomographic microscopy bars, 10 µm). (D) Curves (left panel) were generated with the “Cell Death Assay” module showing the percentage of cell death in PANCO2 mock (solid line) or PANCO2 low FN1 (dashed line) cells over 24 hours. The histogram (right panel) shows the mean area under the preceding curve (+/- SEM) of three independent experiments (t-test, ns = not significant).

(D) Curves (left panel) were generated with the “Cell Death Assay” module showing the percentage of cell death in PANCO2 mock (solid line) or PANCO2 low FN1 (dashed line) cells over 24 hours. The histogram (right panel) shows the mean area under the preceding curve (+/- SEM) of three independent experiments (t-test, ns = not significant). (E) Representative images (left panel) of nine independent experiments of wound healing assay experiments evaluating PANCO2 mock or PANCO2 low FN1 cell migration over 24 hours (10X objective, bars 125 µm). Graph (right panel) shows the mean percentage of area recovery (+/− SEM), from these nine independent experiments, corresponding to the migration of PANCO2 mock or PANCO2 low FN1 cells (5 images per experiment and per well, t-test, ****P < 0,0001). (F) Representative images (left panel) of five independent migration assays to detect PANCO2 mock or PANCO2 low FN1 migrated cells, with Hoechst 33342 after 16 hours. The negative control was performed with the same cells but without FCS in the lower chamber (20X objective, bars 125 µm). Graph (right panel) represents the mean (+/− SEM) of the number of migrated PANCO2 mock or PANCO2 low FN1 cells, from five independent experiments, after 16 hours of incubation (10 images per experiment and per well, t-test, * P = 0.03, n = 5).

Prognostic value of LYZ and LILRB4 proteins in DLBCL receiving R-CHOP ( n = 37, 10X) and aNSCLC receiving ICIs ( n = 29, 2X and 10X). A Representative IHCs staining of LYZ in patient 1 (PFS = 1697 days) and patient 2 (PFS = 341 days), LILRB4 in patient 3 (PFS = 64 days) and patient 4 (PFS = 826 days). B Kaplan–Meier survival curves of PFS grouped by the LYZ and LILRB4 expression in DLBCL. C Representative mIF staining of LYZ, LILRB4, and pan Cytokeratin. D Kaplan–Meier survival curves of OS grouped by the LYZ and LILRB4 expression in aNSCLC. E Kaplan–Meier survival curves of PFS grouped by the COL3A1 expression and FN1 + macrophages in DLBCL. DLBCL: diffuse large B cell lymphoma; R-CHOP: rituximab, cyclophosphamide, doxorubicin: vincristine, and prednisone; aNSCLC: advanced non-small cell lung cancer; ICIs: immune checkpoint inhibitors; IHC: immunohistochemistry; PFS: progression-free survival; mIF: multiple immunofluorescence; and OS: overall survival

Prognostic significance of autoantibodies against COL1A2, COL3A1, and FN1 in patients with DLBCL receiving R-CHOP ( n = 20 and 125) and NSCLC treated with ICIs ( n = 36). A Volcano plot, boxplot, and representative density plots of patients illustrating the distribution of COL1A2 autoantibodies in DLBCL. B Kaplan–Meier curve for PFS based on COL1A2 autoantibody levels in DLBCL. C Kaplan–Meier curves for OS and PFS in NSCLC patients receiving immunotherapy, stratified by COL1A2 and COL3A1 mRNA levels in GSE128989 and autoantibody presence, alongside representative density plots of COL1A2 and COL3A1 autoantibodies. D Comparison of FN1 autoantibody levels between healthy controls and DLBCL, with Kaplan–Meier analysis for PFS based on FN1 autoantibody levels. DLBCL: diffuse large B cell lymphoma; R-CHOP: rituximab, cyclophosphamide, doxorubicin: vincristine, and prednisone; NSCLC: non-small cell lung cancer; ICIs: immune checkpoint inhibitor; OS: overall survival; and PFS: progression-free survival
