Effect of astaxanthin on the mRNA expression level of aquaporin-3 (AQP3) in PHK16-0b (A) and HaCaT (B) cells. Astaxanthin was added to PHK16-0b or HaCaT cells, and the cells were incubated for 6 h. The AQP3 mRNA expression level was measured by real-time RT-PCR. Expression levels were normalized to those of glyceraldehyde-3-phosphate dehydrogenase (GAPDH), and the data are presented as the mean values as a percentage of the control values, which were set to 100% (mean ± SD, n = 4; ** p < 0.01 and *** p < 0.001).
