Effects of an anthocyanin-enriched extract from Vaccinium uliginosum on mRNA expression of (A–C) matrix metalloproteinases (MMPs), (D,E) tissue inhibitor of metalloproteinases (TIMPs), (F) collagen type I alpha 1 chain (COL1a1) and (G) hyaluronidase (HYAL) in UVB-irradiated mouse skin. NOR: normal group; CON: UVB-control group; EL: low dose of ethanol-extracted V. uliginosum-treated group; EM: middle dose of ethanol-extracted V. uliginosum-treated group; EH: high dose of ethanol-extracted V. uliginosum-treated group. Values are means ± standard error of the mean (SEM) for each group. Symbols indicate significant differences at #
p < 0.05, ##
p < 0.01, and ###
p < 0.001 vs. NOR group and * p < 0.05, ** p < 0.01, and *** p < 0.001 vs. CON group.
