Fig. 4From: Coptis chinensis inhibits melanogenesis increasing miR-340-mediated suppression of microphathalmia-associated transcription factor C. chinensis extracts regulated melanogenesis via the miR-340–MITF axis. a C. chinensis-mediated changes in luciferase activity of the miR-340 target sequence. b miR-340-mediated blockade of C. chinensis-induced luciferase activity of the miR-340 target sequence. Statistically significant differences are indicated with an asterisk for p < 0.05Back to article page
