Ginseng compatibility environment-induced toxicity-attenuated effect was a result of crosstalk of inhibition of βAR-Gs-PKA/CaMKII and activation of Epac1/ERK1/2 signaling axis. (A–F) Protein levels of PKA, CaMKII, pSer346-β2AR, pSer355, 356-β2AR, and GRK2 were analyzed. (G–I) Epac1 and the ratio of pERK1/2 to ERK1/2 were detected. The blots were quantified and presented as the fold of control levels. The values represent means ± SEM. P < 0.05, ∗∗P < 0.01 vs. Con; #P < 0.05, ##P < 0.01 vs. Mod; $P < 0.05, $$P < 0.01 vs. FBC.
