    SHP2 and PLCγ are clinically relevant biomarkers for tumor vascular leakage (A and B) Representative multiplex images of RCC patient biopsies. (A) Multiplex images for RCC patients with low vascular PLCγ and SHP2 expression. (B) Multiplex images for RCC patients with high vascular PLCγ and SHP2 expression. Tissue sections were stained for PLCγ (red), SHP2 (yellow), CD34 (green), and FpA (white) to visualize vascular leakage, and counterstained with Hoesht. Scale bars: 100 μm. Boxed regions are shown at higher magnification to the right. Scale bars: 30 μm. (C) Heatmap comparing endothelial SHP2 expression, PLCγ expression, and vascular leakage scores across individual RCC patients ( n = 16). Patients are arranged by their ID number, with color coding indicating high (green), medium (yellow), or low (red) levels. (D) Schematic for the mechanism of SHP2/PLCγ interaction upon VEGFR2 activation. In summary, VEGFA stimuli leads to the phosphorylation of VEGFR2 Y1175, which recruits both PLCγ and SHP2. SHP2 is needed for the activation of PLCγ at the plasma membrane and hydrolysis of PIP2 to IP3 and DAG. The former triggers the release of intracellular calcium (Ca 2+ ), and together with DAG, activates PKC, causing phosphorylation of the eNOS activating site S1177 and dephosphorylation of the inactivating site T495. Production of NO mediates nitration and full activation of Src, which phosphorylates Y685 of VEC, disrupting the adherens junctions and resulting in vascular leakage. Created in BioRender.

    HDCA modulates Treg migration and atherosclerotic plaque composition via FXR signaling. ApoE−/− mice (C57BL/6J background, male, 8 weeks old) were fed a high-fat diet for 28 days to induce AS and subsequently received adoptive transfer of control or FXR-knockout (FXR KO) Treg cells generated by CRISPR/Cas9-mediated lentiviral transduction, with HDCA (30 μM) or vehicle treatment as indicated. (A) Representative Western blot analysis of FXR, PD-1, <t>SHP-2,</t> p-Raptor, RAC and IL-10R expression in isolated Treg cells from each group.

(D) Representative H&E images of aortic sections show the difference between untreated and HDCA-treated mice in the FXR KO groups (magnification, 5 × ; scale bar, 500 μm). Relative bar graphs show quantification of lesion area and lesion/media area ratio.

    SHP2 and PLCγ are clinically relevant biomarkers for tumor vascular leakage (A and B) Representative multiplex images of RCC patient biopsies. (A) Multiplex images for RCC patients with low vascular PLCγ and SHP2 expression. (B) Multiplex images for RCC patients with high vascular PLCγ and SHP2 expression. Tissue sections were stained for PLCγ (red), SHP2 (yellow), CD34 (green), and FpA (white) to visualize vascular leakage, and counterstained with Hoesht. Scale bars: 100 μm. Boxed regions are shown at higher magnification to the right. Scale bars: 30 μm. (C) Heatmap comparing endothelial SHP2 expression, PLCγ expression, and vascular leakage scores across individual RCC patients ( n = 16). Patients are arranged by their ID number, with color coding indicating high (green), medium (yellow), or low (red) levels. (D) Schematic for the mechanism of SHP2/PLCγ interaction upon VEGFR2 activation. In summary, VEGFA stimuli leads to the phosphorylation of VEGFR2 Y1175, which recruits both PLCγ and SHP2. SHP2 is needed for the activation of PLCγ at the plasma membrane and hydrolysis of PIP2 to IP3 and DAG. The former triggers the release of intracellular calcium (Ca 2+ ), and together with DAG, activates PKC, causing phosphorylation of the eNOS activating site S1177 and dephosphorylation of the inactivating site T495. Production of NO mediates nitration and full activation of Src, which phosphorylates Y685 of VEC, disrupting the adherens junctions and resulting in vascular leakage. Created in BioRender.

A: Co-immunoprecipitation (CO-IP) analysis of NFIC and PTEN protein bands in six sample groups; B: CO-IP analysis of OGN and NF-κB protein bands in six sample groups; C: CO-IP analysis of NF-κB and SHP2 protein bands in six sample groups; D: CO-IP analysis of NFIC and OGN protein bands in six sample groups; Data are expressed as mean ± standard deviation. N = 3, P < 0.05 indicates statistically significant difference; * P < 0.05; ** P < 0.01; nsP > 0.05.

    Article Snippet: The membranes were blocked in TBST buffer containing 5% skimmed milk at 37°C for 2 hours, followed by overnight incubation at 4°C with the following primary antibodies: NFIC (CST, #11911, 1:1000), OGN (CST, #24083, 1:1000), NF-κB (CST, #8242, 1:1000), SHP2 (CST, #3752, 1:1000), p-SHP2 (CST, #13379, 1:1000), PI3K (CST, #4292, 1:1000), AKT (CST, #4060, 1:2000), Cyclin A1 (CST, #4656, 1:2000), Cyclin D1 (CST, #2922, 1:1000), MMP-3 (CST, #14351, 1:1000), and MMP-9 (CST, #3852, 1:1000).

    Techniques: Immunoprecipitation, Co-Immunoprecipitation Assay, Standard Deviation

    NFIC binds to the promoter regions of OGN and PTEN and regulates their transcription, leading to increased expression of these two genes. Immunohistochemical staining results for NFIC, PTEN, OGN, NF-κB, and p-SHP2, along with statistical analysis of staining. Data are presented as mean ± standard deviation. N = 3, P < 0.05 indicates statistically significant difference, *P < 0.05, **P < 0.01.

    NFIC promotes OGN and PTEN expression while suppressing NF-κB, SHP2, p-SHP2, PI3K, AKT, Cyclin A1, Cyclin D1, MMP-3, and MMP-9 expression. NF-κB promotes SHP2 expression, while OGN and PTEN inhibit p-SHP2 expression. NFIC suppresses glioma cell proliferation and invasion, whereas NF-κB promotes these processes.
