Strawberry seed extract and its major component, tiliroside, promote ceramide synthesis in the stratum corneum of human epidermal equivalents

Effect of SSE and tiliroside on the mRNA expression levels of GCS and GBA.
3DHEEs models were treated with SSE (1 and 3 μg/mL) or tiliroside (0.1 and 0.3 μg/mL) for 4 days, and total RNA was extracted. mRNA expression levels of GCS (A, B) and GBA (C, D) were determined by real-time qRT-PCR. mRNA expression of GAPDH was used for correction of each mRNA expression. Each column represents mean and S.E. (n = 3–4). Asterisks denote significant difference from control at *P < 0.05 and **P < 0.01.
