The effect of decanal on hyaluronic acid synthesis via the cAMP signaling pathway. Hs68 cells were treated with either decanal or the vehicle and exposed to UVB. Other samples were pretreated with either SQ22536 or the vehicle for 1 h before decanal treatment. (A) Hyaluronic acid concentrations and (B) the mRNA expression of HAS2 were examined. The final hyaluronic acid levels were normalized to the total cellular protein content. Data are shown as the mean ±SEM (n = 3). Significant differences are indicated as * p < 0.05; ** p < 0.01.
