BSZYF treatment promoted the activation of PKC-MAPK and cAMP-PKA signaling pathways. A, the mRNA expression of signal transducers was analyzed by qPCR. B, Western blotting to measure the protein expression of signal transducers. The relative density was quantified relative to tubulin. Values are represented as mean±SD (n=6 per group), *P<0.05 compared with the blank group, #P<0.05 compared with the model group.
