Knockdown of miR-513c-5p promotes pyroptosis of VECs and DVT formation by increasing caspase-1. (A) The expression level of miR-513c-5p in vascular tissue was detected by qRT-PCR in DVT mice treated with INC, miR-513c-5p inhibitor, respectively. (B) Expression of miR-513c-5p in PBMCs was detected by qRT-PCR in DVT mice treated with INC, miR-513c-5p inhibitor, respectively. (C) Confocal microscopy images of miR-513c-5p expression in vascular tissues (miR-513c-5p, red; DAPI, blue) (magnification, ×200). Scale bars = 100 μm. (D) H&E staining of serial cross sections of inferior vena cava (IVC) from DVT mice treated with INC, miR-513c-5p inhibitor at 48 h (magnification, ×40). Scale bars = 500 μm. (E) Representative images of thrombi in each treatment group were detected by vascular ultrasound at 48 h post-operation. (F) Thrombus length and weight at 48 h post-operation in the different treatment groups (n = 15 in each group). (G) Caspase-1 mRNA level was determined by qRT-PCR in vascular tissue of each treatment group. (H) Caspase-1 and GSDMD protein levels were determined by Western blot in vascular tissue of DVT mice treated with INC, miR-513c-5p inhibitor. (I) IL-1β and IL-18 protein levels in vascular tissue were determined by ELISA in INC, miR-513c-5p inhibitor treated DVT mice models, respectively. *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001.
