Article Title: DPPA inhibits melanoma by targeting angiogenesis through activating autocrine IFN-γ-CXCL9/10/11-CXCR3 axis in vascular endothelial cells

doi: 10.1016/j.isci.2026.116309

Figure Lengend Snippet: DPPA suppresses angiogenesis through the activation of the IFN-γ-CXCL9/10/11-CXCR3 axis in vascular endothelial cells (A) Angiogenesis PCR array for human dermal microvascular endothelial cells (HDMECs) treated with DMSO and DPPA at a concentration of 10 μM for 48 h. The relative expression levels were calculated as the log2 fold change, and the differentially expressed genes were selected on the basis of a log2 ≤ −2 or ≥2. (B) KEGG classification of differentially expressed genes in A. HDMECs were treated with DMSO and DPPA (10 μM) for 48 h, and RNAs and proteins were collected to analyze the expression of the IFN-γ-CXCL9/10/11 axis at both the transcriptional and protein levels using RT-qPCR (C) and western blotting (D) assays. n = 3 technical replicates from 3 biological replicates for each group. (E) 3D models of docking poses for DPPA and receptors (including IFN-γ, CXCL9, CXCL10, and CXCL11) predicted by Autodock Vina Tools. (F) 2D model of the interaction between DPPA and IFN-γ. HDMECs were treated with IFN-γ for 48 h, after which the RNAs and proteins were collected and subjected to RT-qPCR (G) and western blotting (H) to quantify the expression levels of CXCL9, CXCL10, CXCL11, p65, and pp65. β-actin was served as an internal control. (G) n = 3 technical replicates from 3 biological replicates for each group. (H) n = 3 biological replicates for each group. (I) HDMECs were treated with NF-κB inhibitor (NF-κB-IN-11) for 48 h, and RNAs were collected to analyze the expression of the IFN-γ at the transcriptional levels using qRT-PCR. β-actin was served as an internal control. n = 3 biological replicates for each group. Cell migration (J) and tube formation on Matrigel (K) of HDMECs treated with DMSO, DPPA, or DPPA with CXCL9/10/11-CXCR3 axis-blocking neutralizing antibodies. n = 3 technical replicates from 3 biological replicates for each group. Scale bars: 100 μm. Data are presented as mean ± SD. Significant effects: p values were calculated using Student’s t test (two-tailed unpaired t test) for C, D, G, H, and I, and one-way ANOVA for J and K. ∗ p < 0.05, ∗∗ p < 0.01, ∗∗∗ p < 0.001 and ns: p > 0.05 (compared with the control/DMSO group).

Article Snippet: Human dermal microvascular endothelial cells (HDMECs, Procell system, Wuhan, China) were maintained in endothelial cell growth medium supplemented with growth supplements (EGM, CC-3124, Lonza), and have been authenticated by Procell system using CD31 immunofluorescence (IF) staining and been tested for mycoplasma contamination.

Article Title: Endothelial Heterogeneity Across Vascular Beds Impacts Inflammatory Signaling and Neutrophil Adhesion

doi: 10.64898/2026.05.26.727909

Figure Lengend Snippet: Multiplexed ELISA of conditioned media from unstimulated umbilical artery (HUAEC), umbilical vein (HUVEC), dermal microvascular (HDMEC), and pulmonary microvascular (HPMEC) endothelial cells. Conditioned media was collected from 1 well per cell type after 16 hours incubation. Samples were analyzed with a Luminex Magpix device and a custom ProcartaPlex inflammation panel. Data are represented as (A) Heatmap normalized across the range for each protein, with darker tones corresponding to higher expression and less expression for lighter tones. Factors that measured below the limit of detection are indicated with an X. (B) log 10 (average expression) ± SEM for N=4 independent experiments. Factors that measured below the limit of detection are indicated with an X. Full statistical analysis with one-way ANOVA and Tukey-Kramer pairwise comparisons testing was done for average expression across all cell types, with results presented in Supplemental Figure 1.

Article Snippet: The following cells were used: pooled human umbilical vein endothelial cells (HUVEC, PromoCell C-12203, Heidelberg, Germany), human umbilical arterial endothelial cells (HUAEC, PromoCell C-12202, Heidelberg, Germany), adult dermal microvascular endothelial cells (HDMEC, PromoCell C-12212, Heidelberg, Germany), and adult pulmonary microvascular endothelial cells (HPMEC, PromoCell C-12281, Heidelberg, Germany).

Figure Lengend Snippet: Multiplexed ELISA of conditioned media from TNF-stimulated (50ng/mL TNF in media) umbilical artery (HUAEC), umbilical vein (HUVEC), dermal microvascular (HDMEC), and pulmonary microvascular (HPMEC) endothelial cells. Conditioned media was collected from 1 well per cell type after 16 hours incubation. Samples were analyzed with a Luminex Magpix device and a custom ProcartaPlex inflammation panel. (A) Heatmap normalized across the range for each protein, with darker tones corresponding to higher expression and less expression for lighter tones. (B) Fold-change expression differences from unstimulated control for factors with >8 fold increase by at least one cell type. Data are average fold change-expression for N=4 independent experiments. One-way ANOVA with Tukey-Kramer pairwise comparisons testing was done for each condition, with asterisks indicating statistical significance between conditions (*p<0.05).
