Overview

In vitro study reveals that nicotinamide mononucleotide reduces melanin production by downregulating tyrosinase in B16F10 cells, indicating its potential for treating skin hyperpigmentation.

Key Points

To investigate the anti-melanogenic effects and underlying molecular mechanisms of nicotinamide mononucleotide (NMN) in α-MSH-stimulated B16F10 melanoma cells.
Assessed cell viability and melanin content in α-MSH-induced B16F10 melanoma cells treated with NMN.
Evaluated catalytic inhibition and active site binding using cell-free mushroom tyrosinase assays and computational molecular docking.
Measured intracellular tyrosinase enzymatic activity and protein abundance using in situ tyrosinase assays, zymography, and Western blot analysis.
NMN maintained greater than 80% cell viability at concentrations below 0.5% while significantly reducing α-MSH-induced melanin accumulation and content.
Cell-free assays and molecular docking confirmed that NMN does not directly interact with the catalytic copper-binding site or inhibit tyrosinase activity.
Tyrosinase zymography and Western blot analyses showed that NMN reduces intracellular melanogenesis primarily by downregulating tyrosinase protein expression.
