Detection of the proteins, which were high expression mRNA under α-thrombin, by immunoblotting. MKN45/PAR1 were stimulated with 15 nM α-thrombin for 3, 6, and 12 hr and harvested for preparing whole cell lysates. The clear extracts containing 100 μg protein was developed on SDS-PAGE. The expression of TN-C, Bcl-2, cIAP1, EGFR and GAPDH protein, which was a house keeping gene product as a control, were detected by Western blotting using specific antibodies against respective proteins (The final dilutions of TN-C, Bcl-2, cIAP1 and EGFR antibodies were 1:500, GAPDH was 1:2000). The MKN45/PAR1 were harvested at 3, 6 and 12 hr after 15 nM α-thrombin stimulation and whole cells were lysed using LIPA buffer. Significant EGFR protein expression was detected in MKN45/mock and unstimulated MKN45/PAR1. The expression above basal level was clearly observed for TN-C, Bcl-2, cIAP1 and EGFR proteins 6 hr after addition of 15 nM α-thrombin.
