Article Title: Inhibition of mPGES-1 attenuates efficient resolution of acute inflammation by enhancing CX3CL1 expression

doi: 10.1038/s41419-021-03423-2

Figure Lengend Snippet: Starting 24 h post i.p. zymosan (5 mg/kg) injection, mice received daily i.p. injections of the mPGES-1 inhibitor compound III (CIII) (25 mg/kg) or the appropriate vehicle control (VEH). Cx3cr1 mRNA expression in A F4/80 lo and B F4/80 hi macrophages (Mϕ) was analyzed by RT-qPCR analysis. C Concentrations of CX3CL1 in the peritoneal lavage were determined by ELISA. D Representative pictures of peritoneal membranes from VEH- and CIII-treated animals at day 6 using multiplexed IHC staining for the epithelial marker pan-cytokeratin (PanCK), CX3CL1, and DAPI. E Quantification of CX3CL1 staining intensity in PanCK-expressing epithelial cells using the InForm-software. F Epithelial E0771 cells were treated with medium supplemented with peritoneal lavages obtained from VEH- or CIII-treated mice at day 6 of the peritonitis model for 4 h. Cx3cl1 mRNA expression was analyzed by RT-qPCR. Data are represented as means ± SEM ( n ≥ 4 per group). For statistical analysis within each treatment, t test or one-way ANOVA with Holm–Sidak posthoc test was used for parametric data, otherwise, Kruskal–Wallis test was used. Analysis between the treatments for parametric data was done via two-way ANOVA with Holm–Sidak posthoc test, non-parametric data were log-transformed (* p < 0.05, ** p < 0.01, *** p < 0.001).

Article Snippet: The relative abundance of CX3CL1 expressing cells in the epithelium was scored upon tissue segmentation based on panCK staining with the InForm software (Akoya Biosciences).

Article Snippet: Slide preparation was performed according to the manufacturer’s protocol (Nanostring GeoMx) with the following digestion and heat-induced epitope retrieval (HIER) conditions: 0.1 μg/ml Proteinase K for 15 min and ER for 20 min. ROI selection (PanCK+/PanCK-) was performed in the GeoMx Digital Spatial Profiler (DSP) based on morphology and immunofluorescence staining with PanCK (Novus Biologicals, clone AE1/AE3, NBP2-33200AF488), SMA (Abcam, clone 1A4, ab202368), CD45 (CST, clone D9M8I, 13917BF), and SYTO 83 DNA staining (ThermoFisher, S11364).

Article Title: Digital Spatial Profiling identifies distinct patterns of immuno-oncology-related gene expression within oropharyngeal tumours in relation to HPV and p16 status

doi: 10.3389/fonc.2024.1428741

Figure Lengend Snippet: GeoMx DSP ROI selection and segmentation approach. (A) Tumour sections were stained with three morphology markers: PanCK (tumour; green), CD3e (T cell marker; yellow), CA-IX (surrogate marker for regions of hypoxia; red), plus a DNA stain to identify all cells (blue). ROIs were placed to identify regions within tumour nests, tumour-stroma interface and peri-tumoural stroma. In this illustrative example from patient 11, ROIs were placed to capture tumour and adjacent stroma in regions of high (ROIs 1, 2, 4, 5) and low (ROIs 3, 6) hypoxia. (B) Segmentation strategy – PanCK staining was used for identification of tumour (PanCK+) and stromal regions (PanCK-), enabling separate analysis. (C) Comparison of keratin gene expression between stromal and tumour compartments. Graph shows combined normalised KRT gene expression for all PanCK- versus PanCK+ segments within each of the 12 patient samples. P values for comparison of PanCK- versus PanCK+ were calculated using unpaired t test, adjusted p values reported as * <0.05, ** <0.005.

Article Snippet: ROIs were segmented into multiple regions representing tumour and stromal (non-tumour) tissue, using a threshold classifier on a fluorescently labelled pan-cytokeratin (PanCK) stain (clone AE1/AE3 594 Novus, 1:200 dilution).

Data were analysed using Kruskal–Wallis test, and pair-wise comparisons were conducted with the Wilcoxon rank-sum test. Adjusted P values (see Supplementary Table 1 ) are reported as: ns, nonsignificant; *P < 0.05; **P < 0.005; ***P < 0.0005; ****P < 0.0001.
