Detection of expression levels of p-AKT, AKT, p-JNK, JNK and NF-κB using western blotting. Cells were divided into four groups when cell confluence reached 60–70%, including a control (NC) group, a cholesterol stimulation (CH) group, a cholesterol stimulation with TRAP-6 treatment (CH+T) group and a cholesterol stimulation with vorapaxar treatment (CH+V) group. Cells were treated with TRAP-6 for 5 min and vorapaxar for 1 h before cholesterol stimulation. After being treated with cholesterol for 24 h, cells were washed with sterile PBS to remove extra cholesterol.

Vorapaxar purchased from MedChemExpress. Usage Cited in: Neoplasia. 2025 May:63:101153. [Abstract]
The effect of thrombin on PAR1 expression was evaluated, and the inhibitory effect of Vorapaxar on PAR1 expression on the cell surface was tested. To reduce baseline signaling activation before treatments, cells were first serum-starved for 12 h. Following starvation, cells were incubated with Thrombin for 1 h to activate PAR1 expression. For inhibition studies, cells were treated with the PAR1 antagonist Vorapaxar (80 µM) for 10 min before thrombin addition.

Immortalized human hepatic stellate cells (LX-2) cells were cultured for 48 hours (48h), then serum starved for 1 hour prior to a 1-hour Fluo4 incubation. Intracellular calcium mobilization was detected by Fluo4 fluorescence in response to thrombin (1 U/mL) or vehicle (Hanks' Balanced Salt Solution) for 2 minutes. Cells were treated with vorapaxar (0.01-10 μM) or vehicle (1% dimethyl sulfoxide in Fluo4 solution) for 1 hour prior to thrombin stimulation. Change in fluorescence relative to baseline following thrombin (or vehicle) stimulation.
