Article Title: Wnts are endothelial cell-derived PKD1/PKD2-dependent autocrine/paracrine vasodilators

doi: 10.64898/2026.03.17.712518

Figure Lengend Snippet: (A) Representative RT-PCR showing that mRNA for PKD1 is present in isolated endothelial cells from tamoxifen-treated Pkd1 fl/fl but absent in isolated endothelial cells from tamoxifen-treated Pkd1 fl/fl :Cdh5(PAC)-CreERT2 mice. Representative of 5 independent experiments for each genotype. (B) Representative Western blots illustrating PKD1, PKD2, AT1, eNOS, Fzd-7 and actin proteins in mesenteric arteries of Pkd1 fl/fl and Pkd1 ecKO mice. (C) Mean data from experiments shown in panel B. Significance was assessed using Student t-tests, n=5 independent mesenteric arterial lysates for each genotype and each protein. (D) Immunofluorescence images (representative of three mesenteric arteries from three mice for each genotype) illustrating that PKD1 (Alexa Fluor 546) is abolished in endothelial cells of en face mesenteric arteries from Pkd1 ecKO mice. CD31 (Alexa Fluor 488) and DAPI are also shown. Scale bars, 50 μm. (E) Diameter responses to intravascular flow (10 dyn/cm 2 ) and intravascular Wnt9b (3 μg/ml) applied in continuous flow in pressurized (80 mmHg) mesenteric arteries from Pkd1 fl/fl and Pkd1 ecKO mice. (F) Diameter responses to intravascular flow (10 dyn/cm 2 ) and intravascular boiled Wnt9b (3 µg/ml) applied under continuous flow (10 dyn/cm 2 ) in pressurized (80 mmHg) mesenteric arteries from Pkd1 fl/fl and Pkd1 ecKO mice. (G) Mean data from experiments shown in panels E and F, and the modulation of flow and Wnt9b-mediated vasodilation by SRI37892 (Fzd-7 Inh, 5 µM). Significance was assessed using a two-way ANOVA with Holm-Sidak post hoc multiple comparisons test. n=10 arteries from 7 mice of each genotype for flow, flow+ Wnt9b and Wnt9b. n=7 arteries from 5 mice for Fzd-7 Inh+flow and Fzd-7 Inh+flow+Wnt9b. n=5 arteries from 5 mice for each genotype for flow + boiled Wnt9b. (H) Diameter responses to intravascular flow (10 dyn/cm 2 ) and intravascular Wnt5a (3 µg/ml). (I) Diameter responses to intravascular flow (10 dyn/cm 2 ) and intravascular boiled Wnt5a (3 µg/ml). (J) Mean data from experiments shown in panels H and I and the modulation of flow and Wnt5a-induced vasodilation by SRI37892 (Fzd-7 Inh, 5 μM). Significance was assessed using two-way ANOVA with Holm-Sidak post hoc multiple comparisons test. n=8 arteries from 6 mice from Pkd1 fl/fl for flow, flow+ Wnt5a. n=5 arteries from 5 mice from Pkd1 ecKO for flow, flow+ Wnt5a. n=5 arteries from 5 mice of each genotype for flow + boiled Wnt5a. n=8 arteries from 6 mice from Pkd1 fl/fl for flow+ Fzd-7 Inh and flow+ Wnt5a+ Fzd-7 Inh.
