Reversine inhibits MMP-1 and 3 expressions by suppressing of ROS/MAPK/AP-1 activation in UV-stimulated human keratinocytes and dermal fibroblasts

Abstract

UVB has been shown to stimulate the generation of ROS, which subsequently results in activation of various intracellular signaling pathways and transcription factors (AP-1, NF-κB), These transcription factors are regulated by MAPKs, which increase cytokine and MMP expression. We examined the preventive effects of reversine on MMP-1 and -3 expressions in NHEKs and NHDFs exposed to UVB irradiation. Also, we confirmed that reversine decreased pro-inflammatory cytokine expression in NHEKs. The mechanism underlying the MMP-inhibitory effects of reversine occurred via the suppression of UVB-induced ROS generation and MAPK/AP-1 activation. Therefore, reversine is an effective therapeutic candidate for preventing skin photoaging.
