doi: 10.3892/mmr.2024.13404
Figure Lengend Snippet: HDBECs (2×10 5 ) were incubated for 24 h with recombinant TF (0, 0.5 and 2 U/ml) or PAR2-AP (SLIGKV; 20 µM), or with recombinant TF (0.5 U/ml) that was pre-incubated for 60 min with 10H10 or HTF1 antibodies (20 µg/ml). Groups of cells were also pre-incubated for 60 min with AIIB2 or SAM11 antibodies (20 µg/ml), prior to the addition of TF. The cells were harvested after 24 h, into separate aliquots (1×10 5 cells). Total RNA was isolated from one group and the mRNA quantified by RT-qPCR, against β-actin. Other aliquots were analysed by western blotting. The data show the amounts of (A) CDK interacting protein/Wildtype p53-activated fragment p21 CIP1/WAF1 mRNA (n=5), and (B) the relative amounts of p21 CIP1/WAF1 protein (n=3) calculated from (C) the western blots of p21 CIP1/WAF1 protein, (using a mouse anti-human antibody) and against GAPDH.

Article Title: Tissue factor signalling modifies the expression and regulation of G1/S checkpoint regulators: Implications during injury and prolonged inflammation
doi: 10.3892/mmr.2024.13404
Figure Lengend Snippet: Proposed model for the mechanism by which the level of TF on the cell surface may have differential outcomes on G1/S checkpoint regulation. The presence of TF on the cell surface differentially upregulates the expression of Inhibitor of CDK p16 INKa , CDK interacting protein/Wildtype p53-activated fragment p21 CIP1/WAF1 and Alternative reading frame p14 ARF , which is dependent on the concentration of TF and the ability of the cell to dissipate excess TF. Therefore, alterations in p21 CIP1/WAF1 are highly effective in the regulation of the cellular response to acute stress. The interplay between these proteins modulates the signal permitting passage through the cell cycle, or alternatively its arrest. Consequently, the concentration of TF may be an ideal gauge for determining the level of cellular damage. However, the adaptive loss of p16 INK4a function may be promoted by prolonged inflammation leading to permissive transition through the G1/S checkpoint, even in the absence of mutational loss of p16 INKa . TF, tissue factor; PAR2, protease-activated receptor 2, Rb, retinoblastoma protein; E2F, early region 2 binding factor; p21 CIP1/WAF1 , CDK interacting protein/wildtype p53-activated fragment; p16 INK4a , inhibitor of CDK; p14 ARF , alternative reading frame.
