Yoon YE, Jung YJ, Lee SJ. A Food Odorant, α-Ionone, Inhibits Skin Cancer Tumorigenesis by Activation of OR10A6. Mol Nutr Food Res 2024; 68:e2400085.

Abstract
SCOPE This study aims to investigate the anticancer properties of α-ionone in squamous cell carcinoma (SCC). METHODS AND RESULTS The expression of OR10A6 together with olfactory receptor signaling components is demonstrated in A431 human SCC cells via RT-PCR and qRT-PCR analysis. OR10A6 activation in A431 cells using the ligand α-ionone inhibits proliferation and migration but induces apoptosis which is confirmed by proliferation assay, colony formation, and western blotting. The mechanism involves the core proteins of the Hippo pathway, where the phosphorylation of large tumor suppressor kinase (LATS), yes-associated protein (YAP), and transcriptional coactivator with PDZ-binding motif (TAZ) is confirmed by western blotting. However, the anticancer effects of α-ionone are abrogated in A431 cells with OR10A6 gene knockdown. In A431 xenograft mouse model, the injection of α-ionone suppresses tumor growth, induces apoptosis, and increases phosphorylation of the LATS-YAP-TAZ signaling axis in the Hippo pathway. None of these effects are observed in xenografted tumors with OR10A6 gene knockdown. CONCLUSION These findings collectively demonstrate that activation of ectopic OR OR10A6 by α-ionone in SCC cells stimulates the Hippo pathway and suppresses tumorigenesis both in vitro and in vivo, suggesting a novel therapeutic candidate for the treatment of SCC.

Sustainable In Silico-Supported Ultrasonic-Assisted Extraction of Oligomeric Stilbenoids from Grapevine Roots Using Natural Deep Eutectic Solvents (NADES) and Stability Study of Potential Ready-to-Use Extracts. Foods 2024; 13:324. [PMID: 38275691 PMCID: PMC10815275 DOI: 10.3390/foods13020324] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2023] [Revised: 01/15/2024] [Accepted: 01/17/2024] [Indexed: 01/27/2024] Open
Abstract
Grapevine roots, as a side-stream of a vineyard, are a sustainable resource for the recovery of oligomeric stilbenoids, such as the bioactive r-viniferin. The aim of this study is to evaluate an in silico-supported method, based on the Conductor-like Screening Model for Real Solvents (COSMO-RS), for selection of environmentally friendly natural deep eutectic solvents (NADES) with regard to the extraction of grapevine roots. The most suitable NADES system for ultrasonic-assisted extraction of r-viniferin was choline chloride/1,2-propanediol. The optimal extraction parameters for r-viniferin were determined using single-factor experiments as follows: choline chloride/1,2-propanediol 1/2 mol/mol, 10 wt% H2O, biomass/NADES ratio 1/10 g/g, and 10 min extraction time. Under optimized conditions, the extraction yield of r-viniferin from grapevine roots reached 76% of the total r-viniferin content. Regarding stability, stilbenoids in choline chloride/1,2-propanediol remained stable during 128 days of storage at ambient temperature. However, fructose/lactic acid-based NADES were observed to degrade stilbenoids; therefore, the removal of the NADES will be of interest, with a suitable method implemented using Amberlite® XAD-16N resin. As green solvents, the NADES have been used as effective and environmentally friendly extractants of stilbenoid-containing extracts from grapevine roots for potential applications in the cosmetic and pharmaceutical industry or as nutraceuticals in the food industry.

Abstract
BACKGROUND Rice has been used for cosmetic purposes for centuries and its benefits have been translated into modern-day skin careproducts. METHODS Pubmed and google were searched with the terms "skin care" and "cosmetics" in conjunction with the words "rice", "rice bran", and "fermented rice bran". Resulting articles were analysed for potential benefits of ingredients contained within rice for skin care and summarised. RESULTS Individual components of rice have been identified including phenolic compounds, betaine, squalene, tricin, and rice bran. These rice-derived ingredients have been found to be antiaging, anti-inflammatory, whitening, photoprotective, and moisturizing. Moreover, rice-derived ingredients have demonstrated benefits for dermatological conditions. Rice bran ash extract increases melanin synthesis and offers protection from radiation and skin injury. Fermented rice bran extract and rice bran broth baths have shown utility in atopic dermatitis treatments. Literature suggests that rice-derived ingredients are also safe, non-irritating, and hypoallergenic. CONCLUSION Ingredients isolated from rice and its components have wide potential for use in skin care and cosmetic products.

Abstract
Ultraviolet B (UVB) radiation is a major environmental causative factor of skin oxidative damage and photoaging. Lacticaseibacillus paracasei is a well-known probiotic strain that can regulate skin health. The present study investigated the effects of heat-killed Lacticaseibacillus paracasei (PL) on UVB linked oxidative damage and photoaging in skin cells (Normal human dermal fibroblast (NHDF) cells and B16F10 murine melanoma cells). Results demonstrated that: (1) PL prevented UVB-induced cytotoxicity relating to decreased DNA damage in NHDF and B16F10 cells; (2) PL alleviated UVB-induced oxidative damage through increasing GSH content, as well as antioxidant enzyme activities and mRNA levels (except MnSOD activity and mRNA levels as well as CAT mRNA level) relating to the activation of Sirt1/PGC-1α/Nrf2 signaling in NHDF cells; (3) PL attenuated UVB-induced photoaging was noticed with a decrease in the percentage of SA-β-gal positive cells in NHDF cells model. Moreover, PL attenuated UVB-induced photoaging through exerting an anti-wrinkling effect by enhancing the type I collagen level relating to the inhibition (JNK, p38)/(c-Fos, c-Jun) of signaling in NHDF cells, and exerting an anti-melanogenic effect by suppressing tyrosinase and TYRP-1 activity and/or expressions relating to the inhibition of PKA/CREB/MITF signaling in B16F10 cells. In conclusion, PL could ameliorate UVB-induced oxidative damage and photoaging. Therefore, PL may be a potential antioxidant and anti-photoaging active ingredient for the cosmetic industry.

Abstract
Halophilic bacteria such as the genus Halomonas are promising candidates in diverse industrial, agricultural and biomedical applications. Here, we successfully isolated a halophilic Halomonas alkaliphila strain XH26 from Xiaochaidan Salt Lake, and studied its osmoadaptation strategies using transcriptome and ectoine analysis. Divergent mechanisms were involved in osmoadaptation at different salinities in H. alkaliphila XH26. At moderate salinity (6% NaCl), increased transcriptions of ABC transporters related to iron (III), phosphate, phosphonate, monosaccharide and oligosaccharide import were observed. At high salinity (15% NaCl), transcriptions of flagellum assembly and cell motility were significantly inhibited. The transcriptional levels of ABC transporter genes related to iron (III) and iron3+-hydroxamate import, glycine betaine and putrescine uptake, and cytochrome biogenesis and assembly were significantly up-regulated. Ectoine synthesis and accumulation was significantly increased under salt stress, and the increased transcriptional expressions of ectoine synthesis genes ectB and ectC may play a key role in high salinity induced osmoadaptation. At extreme high salinity (18% NaCl), 5-hydroxyectoine and ectoine worked together to maintain cell survival. Together these results give valuable insights into the osmoadaptation mechanisms of H. alkaliphila XH26, and provide useful information for further engineering this specific strain for increased ectoine synthesis and related applications.

Abstract
In the present study, we evaluated for the first time the photoprotective effect of fish bone bioactive peptides (FBBP) preparation isolated from silver carp (Hypophthalmichthys molitrix) discarded tissue using in vitro experimental models of skin cells exposed to ultraviolet B (UVB) irradiation and stressing agents. FBBP preparation was obtained by papain treatment of minced bones and centrifugal ultrafiltration, and the molecular weight (MW) distribution was characterized by size exclusion and reversed-phase high performance liquid chromatography (RP-HPLC). In vitro assessment of the effect of FBBP pretreatment in UVB-irradiated L929 fibroblasts and HaCaT keratinocytes revealed their cytoprotective activity. Their capacity to efficiently reduce reactive oxygen species (ROS) production and lipid peroxidation varied in a dose-dependent manner, and it was greater in fibroblasts. A decrease of proinflammatory cytokines secretion, in particular of tumor necrosis factor alpha (TNF-α), was found after FBBP pretreatment of THP-1-derived inflamed macrophages. Melanin production and tyrosinase activity investigated in UVB-irradiated Mel-Juso cells were lowered in direct relation to FBBP concentrations. FBBP fractions with high radical scavenging activity were separated by ion exchange chromatography, and two collagenic sequences were identified. All these results offer new scientific data on aquaculture fish bone-derived peptides confirming their ability to control the antioxidant, anti-inflammatory and pigmentation processes developed during UV irradiation of skin cells and recommend their use as valuable natural ingredients of photoprotective cosmeceutical products.

Abstract
Melanogenesis is the process for the production of melanin, which is the primary cause of human skin pigmentation. Skin-whitening agents are commercially available for those who wish to have a lighter skin complexions. To date, although numerous natural compounds have been proposed to alleviate hyperpigmentation, insufficient attention has been focused on potential natural skin-whitening agents and their mechanism of action from the perspective of compound classification. In the present article, the synthetic process of melanogenesis and associated core signaling pathways are summarized. An overview of the list of natural skin-lightening agents, along with their compound classifications, is also presented, where their efficacy based on their respective mechanisms of action on melanogenesis is discussed.

Polydeoxyribonucleotide Activates Mitochondrial Biogenesis but Reduces MMP-1 Activity and Melanin Biosynthesis in Cultured Skin Cells. Appl Biochem Biotechnol 2019; 191:540-554.

Abstract
The regulation of mitochondrial biogenesis, melanogenesis, and connective tissue proteins is critical for homeostasis and aging skin cells. We examined the biological effects of polydeoxyribonucleotide (PDRN) on mitochondrial biogenesis, melanogenesis, and connective tissue proteins in vitro. In a radical scavenging assay, PDRN showed antioxidant activities in a dose-dependent manner, and those activities can suppress cellular oxidative stress in skin cells. PDRN directly inhibited mushroom tyrosinase activity and cellular tyrosinase activity, thus significantly reducing the cellular melanin content in B16-F10 melanocytes. The mRNA and protein expressions of the microphthalmia-associated transcription factor (MITF), which is a key melanogenic gene transcription factor, were significantly downregulated by PDRN. Accordingly, tyrosinase-related protein 1, dopachrome tautomerase, and tyrosinase, which gene expressions were regulated by MITF, were significantly downregulated by PDRN. Mitotracker-probed mitochondria image analysis suggested that PDRN enhanced mitochondrial density in both murine melanoma cells and in human skin fibroblast cells. In addition, PDRN strongly suppressed in vitro elastase enzyme activity in a dose-dependent manner and inhibited matrix metalloproteinase-1 gene expression in human skin fibroblast cells. Collectively, these findings indicate that PDRN has multiple beneficial biological activities in skin cells: hypopigmentation, induction of mitochondrial biogenesis, and the inhibition of collective tissue proteins.

Liquiritin and Liquiritigenin Induce Melanogenesis via Enhancement of p38 and PKA Signaling Pathways. MEDICINES 2019; 6:medicines6020068.

Abstract
Background: Liquiritin (LQ) and its aglycone, liquiritigenin (LQG), are major flavonoids in licorice root (Glycyrrhiza spp.). Our preliminary screening identified LQ and LQG, which promote melanin synthesis in the melanoma cells. In this study, we investigated the molecular mechanism of melanin synthesis activated by LQ and LQG. Methods: Murine (B16-F1) and human (HMVII) melanoma cell lines were treated with LQ or LQG. After incubation, melanin contents, intracellular tyrosinase activity, and cell viability were evaluated. Protein levels were determined using Western blotting. Results: LQ and LQG activated melanin synthesis and intracellular tyrosinase activity. The induction of melanin and intracellular tyrosinase activity by LQG was higher than that by LQ. LQ and LQG induced the expression of tyrosinase, tyrosinase-related protein (TRP)-1, and TRP-2. LQ and LQG also enhanced microphthalmia-associated transcription factor (MITF) expression, and cyclic AMP-responsive element-binding protein (CREB) phosphorylation. The phosphorylation of p38 and extracellular signal-regulated kinase (ERK), but not Akt, was significantly increased by LQ or LQG. Furthermore, LQ- or LQG-mediated melanin synthesis was partially blocked by p38 inhibitor (SB203580) and protein kinase A (PKA) inhibitor (H-89); however, ERK kinase (MEK) inhibitor (U0126) and phosphatidylinositol-3-kinase (PI3K) inhibitor (LY294002) had no effect. Conclusions: The results suggest that LQ and LQG enhance melanin synthesis by upregulating the expression of melanogenic enzymes, which were activated by p38 and PKA signaling pathways, leading to MITF expression and CREB phosphorylation.
