Fig. 3. Increase of cAMP by PGE2 in RSF.

Fig. 3

Serum-starved RSF were stimulated with or without PGE2 (0.1–10 μM) for the time period as indicated. Levels of cAMP were measured by ELISA. A significant difference from the value of 0 min (A) or non-stimulation (B) determined by Student’s t-test is indicated with a single asterisk (P < 0.05). Values are expressed as means ± standard errors from the number of patients with RA indicated in each panel.
