Article Title: Kindlin-2-Moesin interaction orchestrates sprouting angiogenesis via modulating endothelial membrane mechanics and VEGF signaling

doi: 10.64898/2026.02.24.707842

Figure Lengend Snippet: (A) HUVECs were infected with Ad-Moesin WT or Ad-Moesin T558D for 48 hrs, and total RNA was harvested for RNA-seq. The differentially expressed genes were analyzed with Gene Ontology Enrichment Analysis. The top nine gene sets are shown. Data were analyzed from GSE302986. (B) HUVECs transfected with siCtrl or si KINDLIN-2 were serum-starved (2% FBS) for 8 hrs, then stimulated with 2 μg/mL Alexa 594-labeled VEGF (red) for 30 mins. VEGF accumulation was visualized by confocal microscopy. Actin, phalloidin (green); nuclei, DAPI (blue). (C) Quantification of Alexa 594-labeled VEGF spots normalized to cellular area (n= 4 independent experiments). (D) HUVECs infected with Ad-Moesin WT or Ad-Moesin T558D were starved and stimulated with Alexa 594-labeled VEGF as in (B). VEGF accumulation was imaged by confocal microscopy. (E) Quantification of Alexa 594-labeled VEGF spots normalized to cellular area (n=3 independent experiments). (F) HUVECs transfected with siCtrl or si KINDLIN-2 were serum-starved for 8 hrs, stimulated with 50 ng/ml VEGF for 30 mins, fixed, and stained for VEGFR2 (green). Representative images show intracellular VEGFR2 vesicles. (G) Quantification of VEGFR2 vesicle number per cell from (F) (n=3 independent experiments). (H) HUVECs infected with Ad-Moesin WT or Ad-Moesin T558D were treated as in (F), and stained for VEGFR2. (I) Quantification of VEGFR2 vesicle number per cell from (H) (n= 3 independent experiments). (J) Schematic of the cell surface biotinylation assay. HUVECs were starved for 8 hrs, labeled with EZ-Link Sulfo-NHS-SS-Biotin (0.25 mg/mL) at 4 °C for 1 hr, then stimulated with VEGF (50 ng/mL) for 30 mins. After surface biotin was stripped with GSH elution buffer, total proteins were extracted. Biotinylated internalized VEGFR2 was pulled down using streptavidin magnetic beads and analyzed by western blotting. (K) Cell surface biotinylation assay for VEGFR2 internalization in siCtrl- and si KINDLIN-2 –transfected HUVECs. Input lysates show VEGFR2, Kindlin-2, and GAPDH. “Surf” represents surface VEGFR2 prior to VEGF stimulation and biotin stripping. (L) Quantification of internalized VEGFR2 normalized to surface VEGFR2 levels (n=4 independent experiments). (M) Schematic of in vivo Alexa 594-labeled VEGF uptake assay in Kindlin-2 WT and Kindlin-2 iΔEC(Pdgfb) pups. Tamoxifen was administered from P1 to P3; Alexa 594-labeled VEGF was injected intravitreally at P6 and analyzed after 30 mins. (N) Representative confocal images of the retinal angiogenic front showing uptake of Alexa 594-labeled VEGF by ECs from Kindlin-2 WT and Kindlin-2 iΔEC(Pdgfb) pups. (O) Quantification of internalized Alexa 594-VEGF at the angiogenic front (n = 4/4 pups). (P) Western blot of HUVECs transfected with siCtrl or si KINDLIN-2 , starved for 8 hrs, then stimulated with 50 ng/mL VEGF. (Q) Quantification of p-ERK levels at 5 mins after VEGF stimulation from (P) (n = 4 independent experiments). (R) Western blot of HUVECs infected with Ad-Vector, Ad-Moesin WT , or Ad-Moesin T558D , treated as in (P). (S) Quantification of p-ERK levels at 5 mins after VEGF stimulation from (R) (n = 3 independent experiments). Data are presented as mean ± SEM. * P < 0.05; ** P < 0.01; *** P < 0.001 by two-tailed Student’s t-test or one-way ANOVA followed by Tukey’s multiple comparisons test. Scale bars: 5 μm in (B), (D), (F), (H), and (N).

Article Snippet: Samples were then blocked in PBS containing 2% BSA and 0.1% Triton X-100 for 1 hr at room temperature, followed by staining with primary antibody VEGFR2 (Cell Signaling Technology, #2479S, 1:200) and the appropriate secondary antibody.
