Treatment with TXA attenuated the PARP1/NF-κB signaling pathway.(A) The expression
levels of cleaved PARP1, p65, p-p65 Ser276, p-p65 Ser529, IκBα, p-IκBα, and ICAM-1
were detected by western blotting. The bands were semiquantitatively evaluated by
densitometry, and the data were normalized to those of the internal control,
β-actin. (B) Active p65 was examined through EMSA. The band (active p65) was
semiquantitatively evaluated by densitometry. (C) The content of iNOS, MCP-1, COX-2,
and VCAM-1 was determined by immunohistochemical analysis. The mean density of
staining was calculated as the integrated optical density (IOD) sum/area. a, Sham;
