misPLA analyses of phosphorylation states and protein-protein interactions in SK-BR cells with or without EGF stimulation. A) Phosphorylation targets: SK-BR cells were analyzed for phosphorylation of STAT5a (pSTAT5a), STAT3 (pSTAT3), AKT (pAKT), ERK (pERK), and EGFR (pEGFR), under unstimulated and EGF-stimulated conditions. All targets were visualized three at a time in sequential detection cycles and are shown simultaneously (upper panels, “All targets”) and subsequently as individual channels. PLA signals (red, cyan, green, purple) reflect activated protein states detected via dual-recognition proximity ligation. DAPI (blue) labels nuclei. Scale bars = 50 µm. B) Protein-protein interactions: Visualization of the following protein-protein interactions investigated by misPLA in unstimulated and EGF-stimulated SK-BR cells: MEK1–ERK2, GRB2–MEK1, EGFR–GRB2, STAT3–STAT5a, <t>JAK1–JAK3,</t> JAK1–PI3K, JAK2–STAT5a, JAK1–STAT3, and JAK2–JAK3. Upper panels (“All targets”) represent simultaneous visualization of all targets, imaged three at a time in sequential detection cycles, followed by separated signals per interaction. Scale bars = 50 µm.

misPLA mapping of signaling interactions in a lymph-node Hodgkin lymphoma, mixed cellularity (right neck); Hodgkin lymphoma, lymphocyte-depleted (neck); Hodgkin lymphoma, lymphocyte-predominant (left neck); Hodgkin lymphoma, mixed cellularity (left neck); and thymoma type B3 (mediastinum). Top row (visualization cycle 1) displays MEK1–ERK2 (FITC), EGFR–GRB2 (Cy5) and GRB2–MEK1 (Cy3N) together with DAPI. Middle row (cycle 2) shows STAT3–STAT5a (FITC), JAK1–JAK3 (Cy5) and JAK1–PI3Kp85 (Cy3N). Bottom row (cycle 3) presents JAK2– STAT5a (FITC), JAK2–JAK3 (Cy5) and JAK1–STAT3 (Cy3N). All nine pairs of antibody-oligonucleotide conjugates were applied and then amplified in a single incubation. The RCA products were revealed using detection oligonucleotides conjugated with three fluorophores in three visualization cycles. A standard three-channel fluorescence microscope was used with identical settings for all three fluorophores. Scale bars, 50 µm.

Fig. 4. Inhibition of cytokine-induced STAT and JAK signaling in monocyte-derived macrophages (MDMs) by polyunsaturated fatty acids (PUFAs). (A) Inhibition of IFNb-induced phosphorylation of STAT1 (Y701) by different PUFAs. The p-STAT1 antibody recognizes both the STAT1a and b isoforms. (B) Inhibition of IFNc-induced phosphorylation of STAT1 by different PUFAs. (C) Inhibition of IL-6 induced phosphor- ylation of STAT3 (Y705) by different PUFAs. AA, arachidonic acid; LA, linoleic acid; EPA, eicosapentaenoic acid; DHA, docosahexaenoic acid; ETYA, 5,8,11,14-eicosatetraynoic acid. (D) Inhibition of IFNb-induced phosphorylation of JAK1 (Y1034/1035) by AA. (E) Inhibition of IFNc- induced phosphorylation of JAK2 (Y1007/Y1008) by AA. In each case, MDMs were pretreated with 50 µM of the indicated PUFA for 30 min prior to stimulation with the IFNb, IFNc or IL-6 for 30 min. A representative immunoblot and the quantification of n = 7 (A–C) or n = 5 (D–E) independent experiments (different donors; indicated by different symbols) are shown in each panel. Statistical significance was analyzed by paired t test (*P < 0.05; **P < 0.01; ***P < 0.001; ****P < 0.0001; ns, not significant). Horizontal lines indicate the median.

Fig. 11. Model of arachidonic acid (AA) regulated signal transduction pathways triggered by pro-inflammatory mediators. AA interferes with the lipid-raft association of pro-inflammatory cytokine receptors, receptor-associated JAK protein kinases and STAT proteins. This mislocaliza- tion impairs the cytokine-triggered phosphorylation and activation of JAK1/2 and STAT1/3, and thereby induction of their target genes.
