Figure Lengend Snippet: CSP NPs inhibit NF-κB/NLRP3 signaling pathway during vascular calcification. Rat vascular smooth muscle cells (VSMCs) were treated with growth medium (GM), calcifying medium (CM), or CM with CSP NPs (2, 5, and 10 μg/mL) for 7 days (n = 4). (A) Representative western blots of p-p65 and p65. (B) Quantification of p-p65 protein expression by densitometry. Rat VSMCs were treated with GM, CM, or CM with CSP NPs (10 μg/mL) for 7 days (n = 4). (C) Representative immunostaining images of p65. Nuclear localization of p65 was determined by confocal microscopy. Scale bar = 25 μm. Rat VSMCs were treated with GM, CM, or CM with CSP NPs (2, 5, and 10 μg/mL) for 7 days (n = 4). (D) Representative western blots of NLRP3, Cleaved-Caspase1, IL-1β, and IL-6. (E) Quantification of NLRP3, Cleaved-Caspase1, IL-1β, and IL-6 protein expression by densitometry. VitD 3 -overloaded mice were treated with CSP NPs (1 mg/kg) for 8 days (n = 6). (F) Representative western blots of p-p65, p65, and NLRP3. (G) Quantification of p-p65 and NLRP3 protein expression by densitometry. Rats subjected to 5/6 nephrectomy were treated with CSP NPs (0.7 mg/kg) for 4 weeks (n = 6). (H) Representative western blots of p-p65, p65, and NLRP3. (I) Quantification of p-p65 and NLRP3 protein expression by densitometry. ∗ P< 0.05, ∗∗ P< 0.01.
