Figure 1

The expression of PAR1 mRNA and protein in gastric cancer cell lines. (A) The expression of PAR1 mRNA in 7 gastric cancer cell lines by RT-PCR. PAR1 mRNA was confirmed in MKN28, MKN74 and NUGC3.

(B) Parent MKN45 cells and MKN45 cells transfected with pcDNA3.1-empty-vector alone (designated as MKN45/mock) have no detectable expression of PAR1 protein, and MKN28 and MKN45 cells transfected with PAR1 cDNA bearing pCDNA3.1 vector, which was treated 750 μg/ml G418 to select permanent PAR1 expressing clone, (designated as MKN45/PAR1) was confirmed to continuously express high level PAR1 protein by immunoblotting (upper panel). The bottom panel showed a protein band of a house keeping gene, GAPDH as a control.

(The final dilution of PAR1 antibody was 1:500, GAPDH was 1:2000.)
