英文摘要Aims: Silk fibroin (SF), a natural product from silkworms, has been used to promote anti-inflammation, induce wound healing, and reduce melanin production. However, the underlying regulatory mechanism of SF on melanin production remains unknown. The aim of this study was to investigate the distinct regulatory mechanism of SF in B16 melanoma cells by applying quantitative proteomic approach. Materials and methods: B16 melanoma cells were treated with PBS, KA or SF for 48 h, respectively. Cell viability, melanin content, and tyrosinase activity were examined. A label-free quantitative proteomic approach was utilized to investigate the regulatory mechanism of SF. The differentially expressed proteins and their related biological processes were subsequently identified by bioinformatics methods. Furthermore, the identified differentially expressed proteins were validated by western blot. Key findings: Both SF and KA were able to suppress the melanin synthesis of B16 melanoma cells without appreciable toxicity; yet, SF had a distinct effect on mushroom tyrosinase activity in vitro. Moreover, quantitative proteomic approach identified 141 proteins differentially expressed only in SF/Con group. Bioinformatic analysis of these proteins revealed that oxidation-reduction process, RNA processing, fatty acid degradation, as well as melanin biosynthetic process were enriched with SF treatment. The proteins associated with melanin biosynthetic process, including microphthalmia-associated transcription factor (MITF) and tyrosinase, were downregulated in SF group, which was confirmed by western blot. Significance: SF inhibited melanin synthesis in B16 melanoma cells via down-regulation of MITF and tyrosinase expression, which provides a rationale for future utilization of SF.
