The scale bar in each image represents 5 μm. ( E ) Components of the Pol I transcription machinery could be precipitated by the BRF1 antibody. HeLa nuclear extract was prepared and used for BRF1 IP assays. BRF1-binding proteins in the IP samples were detected by Western blot using the antibodies as indicated in the panel. ( F , G ) BRF1 could be precipitated by the antibodies against Pol I-related proteins. IP assays were performed with the antibodies against TBP, TIF-1A, TAF1A, UBF, and RPA43, respectively.

The mixture of APS total IgG and β2GPI induces a pronounced increase of the protein levels of the proinflammatory cytokines IL-6, IL-8 as well the transcription factor NF-κB1 and cell adhesion molecules Tissue Factor, ICAM-1, VCAM-1, Eselectin, P- selectin and TGFR1. There was no significant difference for the TGFR1 molecule (3 J). Visual analysis revealed that all the inflammatory mediators and adhesion molecules presented statistically significant difference between the untreated and treated endothelial cells (3 K).
