Argan Oil

The beneficial effect on health of argan oil is recognized worldwide. We have previously reported that the cake that remains after argan oil extraction (argan press-cake or APC) inhibits melanogenesis in B16 melanoma cells in a time-dependent manner without cytotoxicity. In this study, the global gene expression profile of B16 melanoma cells treated with APC extract was determined in order to gain an understanding of the possible mechanisms of action of APC. The results suggest that APC extract inhibits melanin biosynthesis by down-regulating microphthalmia-associated transcription factor (Mitf) and its downstream signaling pathway through JNK signaling activation, and the inhibition of Wnt/β-catenin and cAMP/PKA signaling pathways. APC extract also prevented the transport of melanosomes by down-regulating Rab27a expression. These results suggest that APC may be an important natural skin whitening product and pharmacological agent used for clinical treatment of pigmentary disorders.

Phlorotannins isolated from brown algae, such as Eisena bicyclis, have positive physiological effects, including anti-cancer, anti-inflammatory, and anti-Alzheimer’s disease. Although phlorotannins have been shown to inhibit tyrosinase, an enzyme essential for melanogenesis, their effect on melanogenesis remains unexplored. Thus, we isolated phlorotannins from E. bicyclis and examined their effects on α-melanocyte-stimulating hormone (α-MSH)-induced melanogenesis in murine B16 melanoma cells. Both fucofuroeckol-A (FF-A) and phlorofucofuroeckol-A (PFF-A) suppressed α-MSH-induced melanogenesis. Neither inhibited human tyrosinase (TYR) activity, but both inhibited tyrosinase-related protein-2 activity. FF-A downregulated the expression of microphthalmia-associated transcription factor and TYR, which subsequently suppressed melanin production. These results suggest that phlorotannins could be beneficial as melanin control drugs for hyperpigmentation disorders.

Tumor Metastases

This study examined the effects of moderate and prolonged exercise on 1) lung tumor metastases and 2) alveolar macrophage antitumor response in vitro. C57Bl/6 mice were assigned to either Ex-30 (30-min run), Ex-F (run to fatigue), Ex-F-24 h (run to fatigue 24 h before tumor injection), or Con (rested in lanes above the treadmill). Mice received intravenous injections of syngeneic B16 melanoma cells 30 min postexercise. Lungs were removed 7 or 10 days later, and tumor foci were counted. Ex-F had fewer tumors than either Ex-30 or Con, whereas Ex-F-24 h also showed a strong trend toward fewer tumors. The initial localization of tumor cells in the lungs after injection was not different among groups. For the in vitro experiment, mice were killed immediately after exercise or 8 h later. Alveolar macrophages were removed and cultured in vitro with B16 melanoma cells. The growth of the tumors cultured with macrophages from Ex-F was lower than Con after exercise and, to a lesser extent, 8 h later. In Ex-30, this effect was only found immediately after exercise. The data suggest that prolonged exercise has a protective effect on lung tumor metastases and enhances alveolar macrophage antitumor cytotoxicity.
