Metabolites in lipid extracts from the mouse liver that were significantly different between the normal and UVB groups after 6 weeks and were tentatively identified using nanomate LTQ-MS analysis.

Variables were selected by VIP value (>0.7) and p value (<0.05) from OPLS-DA models.
aFold change was calculated by dividing the mean of the peak intensity of each metabolite from the UVB-radiated group by that of the normal group.
bVIP, variable important in the projection.
