S1P5-dependent regulation of S1P1 and S1P3 mRNA in BLM-treated skin. Relative mRNA expression of (A) S1P1 and (B) S1P3 in skin tissue of BLM-treated WT (black bars) and S1P5−/− (gray bars) mice. mRNA expression levels were determined by qRT-PCR analysis. All data are presented as fold change to the mean of the respective PBS controls and shown as mean ± SD of n = 3–5 mice/group with #/* indicating p ≤ 0.05, ## for p ≤ 0.01 and *** for p ≤ 0.001. Hashtags (#) characterize significance in comparison to the respective PBS controls (adjacent white bars). Statistical analysis was performed using a one sample t-test for # or an unpaired t-test for *. (rel. = relative). BLM, bleomycin; PBS, phosphate-buffered saline; qRT-PCR, quantitative real-time polymerase chain reaction; WT, wild type.
