Figure 1. HNSCC cell lines express COX-2, EP1, EP2 and EP3 but not EP4 A.

Figure 1

COX-2 expression in HN13, UMSCC17, Cal27, OSCC3 and HN30. B. Expression of the indicated EP receptors was examined in HNSCC cell lines and NOK-SI. Transfected HEK 293T with EP1, EP2, EP3 and EP4 cDNAs (as described in 20) were used as positive controls. GAPDH was used as loading control.
