Thrombin Induces COX-2 and PGE2 Expression via PAR1/PKCalpha/MAPK-Dependent NF-kappaB Activation in Human Tracheal Smooth Muscle Cells

Figure 7

Schematic diagram illustrating the proposed signaling pathway involved in thrombin-induced COX-2 expression and PGE2 secretion in HTSMCs. Thrombin-induced COX-2 expression associated with PGE2 generation was mediated through PAR1/Gq or Gi/o/PKCα/MAPK-dependent NF-κB activation in HTSMCs.
