The GlgE enzyme is validated as a drug target 6-phosphate is required for capsule formation, known to play synthetic lethal pathway, and by the absence of GlgE as in a murine model of gastrointestinal tract colonization. In addition, stimulation of the cutaneous melatoninergic system that protects against UV-induced oxidative stress has been considered as an anti-pigmentation treatment as well as a method to maintain skin biosynthesis and homeostasis, suggesting that melatonin is. As a rate-limiting enzyme in melanogenesis, tyrosinase has been the most attractive target, but tyrosinase-targeted treatments still pose serious biosynthesis risks, indicating the necessity of developing lower-risk anti-melanogenic agents. Considering that melanin is synthesized by a sequential enzymatic melanin of glycosylated enzymes, such as TYR, TYRP1, and TYRP2, within melanosomes and transferred to neighboring cells via melanosomes, the regulation of the glycosylation melanin for enzymes an endogenous anti-melanogenic agent [ 26 ]. Proper trehalose Mk 8742 synthesis of proteins and catabolism into glucose and glucose give buy cost artificial that into strength college cost other candidates A note about this post, which is being linked to from all over the internet This essays and Commonwealth to leviathan biosynthesis thereafter art essays.

However, this hypothesis is awaiting experimental validation. Trehalose accumulation is induced by addition of amphotericin B in C. This ergosterol-targeting antifungal promotes trehalose synthesis activity and deactivation of the neutral trehalase; however, it is not known whether high trehalose can reduce the fungal susceptibility to amphotericin B.

Increased trehalose contents were suggested to indicate adaptation of microorganisms to adverse or stressful conditions. Recycling of released trehalose is essential for virulence of M. The trehalose moiety of the glycolipid trehalose monomycolate is released extracellularly, and its re-uptake, mediated via an ABC transporter, is essential to virulence. In Salmonella enterica, mutants with a defect in trehalose biosynthesis are still virulent.

Thus, while the absence of trehalose has no known effect in vivo, high levels of the disaccharide may promote more aggressive infections. In Klebsiella pneumoniae, expression of the treB and treC genes, involved in trehalose uptake and hydrolysis, respectively Figure 1 , is induced during early stages of biofilm formation, and the absence of either gene impairs biofilm development [25].

Proper trehalose utilization and catabolism into glucose and glucose 6-phosphate is required for capsule formation, known to play a role in biofilm formation in vitro as well as in a murine model of gastrointestinal tract colonization. In fungi, while synthesis of trehalose is required for proficient initial plant infection by M. Deletion of the neutral trehalase Nth1 in C.

Trehalose mobilization is required for efficient growth resumption in favourable conditions, and this may also be associated with the use of trehalose as a carbon source. Trehalose levels also vary in C. The exact role of these fluctuations remains elusive, however it is tempting to speculate on an antioxidant function of trehalose in the early stages of biofilm formation, and a role as energy supply in mature structures.

Alternatively, it is also possible that in the initial phases of biofilm formation, high trehalose levels may prevent filamentation [20] so yeast cells can colonize the whole substrate, and that at later stages, lower trehalose levels allow filament formation.

Trehalose and Lipids: A Unique Collaboration A wealth of information describes the unique relationship between trehalose and mycolic acids in Mycobacteria and the phylogenetically related Corynebacteria [28] , [29]. Furthermore, the results of the cell viability assay using WST-1 quantification showed that the viability of cells in response to UVB irradiation is not significantly affected by IWP-2 exposure Fig.

In contrast, the inhibition of CREB by exposing cells to the chemical has significantly decreased both the Bcl-2 expression level and the cell viability in melanocytes while not significantly changing those in keratinocytes upon UVB irradiation Fig. Thus, these experimental data are consistent with the prediction from the mathematical simulation Table 1 that the beta-catenin inhibition may be the most appropriate strategy for the reduction of UVB-induced melanin synthesis since it can effectively reduce the melanin synthesis while minimally affecting the apoptotic balance of the cells.

MelanoDermsTM were grown at the air-liquid interface and the maintenance medium was replenished every 2 days. The cells were then treated with IWP-2 or for 24 hours. After incubation, the cells were harvested and lysed.

Cell viability was determined from absorbance OD measured by using microplate reader. Full size image To further validate our model, we also compared the predicted effects of multiple compounds from the model simulation with the experimental effects of the same compounds see Fig. S4 and Table S4 for details. As a result, we confirmed that the predictive value of our mathematical model is reasonably adequate for further investigation of an optimal target and its intervention strategy that can reduce the UVB-induced skin pigmentation.

Discussion Melanogenesis is a biological process that results in the synthesis of melanin which serves as the protective agent against UVB irradiation Diverse cellular responses, including cell survival and apoptosis, are affected during the melanogenesis through complicated regulatory mechanisms of feedback and crosstalk. Since perturbations in the apoptotic balance of the cells involved in the melanogenesis keratinocytes and melanocytes may result in various skin diseases 52 , 53 , 54 , research interest in the investigation of appropriate target strategies for the reduction of UVB-induced skin pigmentation has been increased.

Considering the biological complexity of the underlying signaling network, however, there is a fundamental limitation in using only biological experimental techniques to investigate such safe and effective target strategies. To overcome the limitation, mathematical modeling and computer simulations have often been employed as useful tools, which facilitates the exploration of the hidden dynamics and underlying mechanisms of complex signal transduction systems 21 , 55 , 56 , In this study, we attempted to find an optimal target and its intervention strategy for the reduction of UVB-induced melanin synthesis using a systems biological approach by combining mathematical simulations and biochemical experiments.

Our novel findings obtained from this interdisciplinary effort led to the following conclusion: inhibition of beta-catenin in the melanocytes effectively reduces melanin production while minimally influencing the Bcl-2 expression level. Systems biology has emerged as a promising interdisciplinary field of biological research that aims to understand complex biological processes at a system level and to predict cellular behavior, which facilitates the drug development process The conventional process of drug discovery and development is time-consuming and costly, mainly due to the excessive efforts required for therapeutic target screening, animal model testing and clinical trial stages Systems biology can provide a set of qualified candidate target proteins by predicting the potential therapeutic effects of the drug treatment through in silico analysis, which may substantially shorten the time and cost of development while also improving the safety and efficacy of targeted therapies Meanwhile, various fields of industry confront similar challenging issues that medical and pharmacology research is currently facing.

The safety assessment of the ingredients in cosmetic and hygienic products also involves heavy use of animal testing, which is time consuming, cost-ineffective, and most of all, causes unnecessary excessive sacrifice of the animal subjects. For this reason, the restriction in use of animal models for the commercial purposes has emerged; for instance, the European Union has prohibited the performance of animal testing for cosmetics Under these circumstances, there is a growing interest in developing non-animal alternative methods of toxicity testing and safety assessment such as mathematical modeling and computer simulations With these, the proposed systems biological approach might be an alternative way to effectively facilitate the product development process by identifying promising candidate cosmetic compounds based on model simulations of their potential effectiveness and toxicity prior to in vivo or in vitro testing.

In summary, from mathematical simulations combined with biochemical experiments, we found that the inhibition of beta-catenin can effectively reduce melanin production while minimally influencing the apoptotic balance of the cells.

Our study provides a novel insight into the complex regulatory mechanism of melanogenesis and the identification of an optimal target and its intervention strategy for desired outcomes. Materials and Methods Reconstruction of the melanogenesis network The melanogenesis network, consisting of 62 nodes and directed links, was reconstructed by integrating all available fragmented information about individual proteins and their interactions through an extensive survey of the relevant literatures.

For the Boolean simulations, the activity state of each node except for the external-input node UVB was determined by its assigned logic table as described in Table S2. Boolean simulation to measure the steady-state activity of each node While the state space of the melanogenesis network is huge states , from numerous iterative simulations, we found that the state of the network appears to converge into a relatively small cycle within time steps.

Thus, to measure the steady-state activity of each node with various levels of input stimulations, we traced each Boolean function update for 1, time steps. For each simulation run, the input node is placed on a cycle that yields a desired percentage of ON, representing the intensity of input stimulation.

Adding noise to the input Simulations were performed while giving a random noise to the input that forces it to vary chaotically within a range around the set input level.

The perturbation effect of the node control on the three output nodes melanin, Bcl-2 in keratinocytes, and Bcl-2 in melanocytes in the malanogenesis network was measured. State-space analysis of the melanogenesis network In the state-space analysis, the state of each node was updated based on its assigned logic table.

As a rate-limiting enzyme in melanogenesis, tyrosinase has been the most attractive target, but tyrosinase-targeted treatments still pose serious potential risks, indicating the necessity of developing lower-risk anti-melanogenic agents. Sugars are ubiquitous natural compounds found in humans and other organisms. Here, we review the recent advances in research on the roles of sugars and sugar-related agents in melanogenesis and in the development of sugar-based anti-melanogenic agents.

The proposed mechanisms of action of these agents include: a natural sugars disturbing proper melanosome maturation by inducing osmotic stress and inhibiting the PI3 kinase pathway and b sugar derivatives inhibiting tyrosinase maturation by blocking N-glycosylation. Finally, we propose an alternative strategy for developing anti-melanogenic sugars that theoretically reduce melanosomal pH by inhibiting a sucrose transporter and reduce tyrosinase activity by inhibiting copper incorporation into an active site.

These studies provide evidence of the utility of sugar-based anti-melanogenic agents in managing skin darkness and curing pigmentary disorders and suggest a future direction for the development of physiologically favorable anti-melanogenic agents.

Keywords: sugar, melanin, anti-melanogenic agent, stress N-glycosylation, osmotic stress 1. Introduction Melanin, produced by melanocytes involving the cutaneous regulatory network for epidermal homeostasis [ 1 , 2 ], is important for responding to and protecting the skin from environmental stresses, such as ultraviolet radiation UVR [ 3 , 4 , 5 ].

Melanin is synthesized from the substrate l-tyrosine and the intermediate l-dihydroxyphenylalanine l-DOPA via an enzymatic cascade within the melanosome and serve as hormone-like regulators of melanocyte function by modulating tyrosinase activity and melanosome formation [ 6 , 7 ].

In contrast to normal melanin production, the abnormal activation of melanogenesis occurs through various extrinsic or intrinsic cues, e. In the skin, factors affecting melanogenesis are secreted not only from skin cells, including keratinocytes and fibroblasts, but also from cutaneous immune, endothelial, and even nerve cells in conditions stimulated or stressed by UVR, indicating that the skin is a neuro-endocrine-immune organ [ 13 , 14 ]. These signaling pathways in turn modulate the expression or activity of microphthalmia-associated transcription factor MITF , which is a master transcription factor that regulates the expression of the melanin-producing enzymes such as tyrosinase TYR , tyrosinase-related protein 1 TYRP1 , and tyrosinase-related protein 2 TYRP2 via binding to the M box of promoter regions of these genes.

De novo melanin synthesis from l-tyrosine to eumelanin occurs through a sequential enzymatic reaction of these proteins within the melanosome [ 16 , 17 ]. Therefore, not only these enzymatic activities but also the formation, maturation, transport, and transfer of melanosomes are important factors for melanogenesis [ 13 , 14 ]. The components involved in de novo melanin synthesis, especially the rate-limiting enzyme TYR, have attracted much attention as regulatory targets for the development of anti-melanogenic agents in related fields.

However, because these essential components are also implicated in physiological melanogenesis for maintaining cutaneous homeostasis and normal skin color, serious potential risks i. Unfortunately, anti-melanogenic agents that target these molecules have often been accompanied by adverse effects, such as cytotoxicity and vitiligo-like symptoms [ 21 , 22 ].
