J) Representative western blot membranes and corresponding densitometric analyses of (K) TF, (L) PAI‐1, (M) Thrombin in lung tissue (n = 6/group). N) mRNA levels of TF in murine lung tissues (n = 5/group). O–Q) mRNA levels of (O) IL‐1β, (P) IL‐6, and (Q) TNF‐ɑ in murine lung tissues (n = 5/group). R) Survival curves of mice in all groups (n = 10/group). Each bar represents the mean ± SD. Statistical analysis for three or more groups was carried out using one‐way ANOVA (C‐H and K‐Q). * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001.

Article Snippet: The concentrations of PIM1 (CSB‐ E11825 h, Cusabio, China) in human plasma and TAT (CSB‐ E08433 m, Cusabio, China), Fbg (CSB‐ E08202 m, Cusabio, China), and D2D (CSB‐ E13584 m, Cusabio, China) in mouse plasma were assessed using ELISA kits according to the guidelines outlined in the respective ELISA kits.

Article Title: Thrombin increases the expression of cholesterol 25-hydroxylase in rat astrocytes after spinal cord injury.

doi: 10.4103/1673-5374.357905

Figure Lengend Snippet: Figure 1 ｜Quantitative changes in thrombin production and cholesterol hydroxylase expression at the lesion site following spinal cord injury (SCI) in a rat model. (A) Experimental design. Experiment I was designed to investigate the effects of the protease-activated receptor 1 (PAR1) inhibitor SCH79797 on thrombin- induced cholesterol-25-hydroxylase (CH25H) expression by astrocytes. For quantitative polymerase chain reaction, enzyme-linked immunosorbent assay, tissue immunofluorescence, and hematoxylin-eosin staining, 1 cm spinal cord segments were harvested from rats at each time point. Experiment II was designed to investigate the effects of rat motor function after SCH79797 treatment. (B) Enzyme-linked immunosorbent assay of thrombin production at 0, 1, 4, and 7 days following SCI. Day 0 was used as the control. (C–E) RNA levels of ch25h, cyp46a1, and cyp27a1 at the lesion site were determined by quantitative polymerase chain reaction at different time points with or without injection of 4.5 μL of 5 mM SCH79797. Quantities were normalized to gapdh levels on day 0. Data are expressed as mean ± SEM (n = 3). *P < 0.05 (independent sample t-test). DMSO: Dimethyl sulfoxide; gapdh: glyceraldehyde-3-phosphate dehydrogenase.

Article Snippet: After centrifuging at 2750 × g for 5–10 minutes at 2–8°C, the supernatant was subjected to thrombin enzyme-linked immunosorbent assay (ELISA) using a kit (Rat TAT ELISA Kit, Elabscience) according to the manufacturer’s directions.

Article Title: IKKβ regulates the expression of coagulation and fibrinolysis factors through the NF-κB canonical pathway in LPS-stimulated alveolar epithelial cells type II.

doi: 10.3892/etm.2019.7928

Figure Lengend Snippet: Figure 3. Over‑expression of IKKβ promotes secretions of TAT, TM, PIIIP and PAI‑1, and inhibits ATIII production, while low‑expression has inverse effects on these molecules from LPS‑stimulated AEC II. Bar graphs of concentrations about the indicators above as assessed by enzyme‑linked immunosorbent assays in cell‑supernatant of each group. Values are presented as the mean ± standard deviation; aP<0.05 vs. the ctrl, bP<0.05 vs. the LPS group as determined by one‑way analysis of variance. TAT, thrombin‑antithrombin; ATIII, antithrombin III; TM, thrombomodulin; PIIIP, procollagen III N terminal peptide; ctrl, control; AEC II, alveolar epithelial cell type II; LPS, lipopolysaccharide; NC, negative control; sh, short hairpin.
