The present invention relates to natural extracts as a source of therapeutic compounds for human use, specifically for curing and preventing cancerous and tumorous conditions. Biopelle Tensage Antioxidant Defense Serum. An extract from the plant Deschampsia antarctica protects fibroblasts from senescence induced by hydrogen peroxide. Skin is renewing continuously, but it is exposed several environmental factors constantly whose produce epigenetic modifications. The present invention relates to methods of preparing aqueous extracts of D. antarctica having anti-oxidant and anti-inflammatory properties as well as to pharmaceutical compositions comprising aqueous extracts of D. antarctica at concentrations useful in the prevention of aging in humans as well as for the prevention of photoaging effects generated by exposure to harmful ultraviolet radiation. Different concentrations of TCDD (15–300 nM) were tested on human dermal fibroblasts and keratinocytes at different incubation times, always without exceeding a final DMSO concentration of 0.1% (Sigma, Saint Louis, MO, USA). Please note that many of the page functionalities won't work as expected without javascript enabled. Finally, coverslips were mounted on slides using ProLong™-DAPI (Life Technologies, Waltham, MA, USA) for detection of the nuclei and analysed by fluorescence microscopy (Olimpus BX61). (Angiosperm: family Graminaceae) plants were collected from Robert Island, South Shetland Islands, Maritime Antarctic, during February, 1992 and January, 1993, and were extracted with 80% ethanol. Cell viability in HaCaT and HDF cells after different treatments was determined by MTT assay. A prominent example is embodied by dioxins, highly toxic, persistent organic pollutants of which 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) is a prototypical species. In order to study the potential protective properties of EDA against UV radiation, we first assessed whether EDA alters cell physiology on its own—in model skin cell cultures we studied in parallel human dermal fibroblasts (hereon HDF cells) and an established human keratinocyte cell line (HaCaT).

Their activity is tightly regulated by endogenous inhibitors the tissue inhibitor of metalloproteinases (TIMPs). The regulation mechanisms of AhR by molecular chaperone complex. Exposure to natural and artificial light and environmental pollutants are the main factors that challenge skin homeostasis, promoting aging or even different forms of skin cancer through a variety of mechanisms that include accumulation of reactive oxygen species (ROS), engagement of DNA damage responses, and extracellular matrix (ECM) remodeling upon release of metalloproteases (MMPs). Author to whom correspondence should be addressed. Ozone are agonist of AhR [10]. Linden, J.; Lensu, S.; Tuomisto, J.; Pohjanvirta, R. Dioxins, the aryl hydrocarbon receptor and the central regulation of energy balance. An aqueous extract of Deschampsia antarctica (EDA) exerts clear protective effects on human skin cell against dioxins treatments. 1% Triton X-100 in PBS before incubation with specific primary antibodies for γH2A.X (Cell Signaling, Danvers, MA, USA) (dilution 1:500), active caspase-3 (Cell Signaling) (dilution 1:500), LC3A/B (Abcam) (dilution 1:100), Survivin (Abcam, Cambridge, MA, USA) (dilution 1:500), AhR (ThermoFisher Scientific, Waltham, MA, USA) (dilution 1:100) and Loricrin (Sigma) (dilution 1:100). In addition, different chemicals contribute to skin aging upon penetration through skin barrier disruption or hair follicles, aryl hydrocarbon receptors (AhR) being a major effector mechanism through which toxicity is exerted. Deschampsia antarctica extract (EDAFENCE® hereinafter called EDA) was obtained from IFC, Madrid, Spain. S.R.L. Its aqueous extract (EDA) exhibits anti- photoaging in human skin cells, such as inhibition of MMPs, directly associated with extrinsic aging. Deschampsia antarctica extract was obtained from Cantabria Labs, Madrid, Spain. Modulation of proteostasis by transcription factor NRF2 and impact in neurodegenerative diseases. 2.1. The role of photochemical quenching and antioxidants in photoprotection of Deschampsia antarctica. The statements, opinions and data contained in the journals are solely In this work, antioxidant physiology of D. antarctica was studied in response to UVB induced oxidative changes. Deschampsia antarctica is a polyextremophile Gramineae capable of thriving under extreme environmental conditions. Kohler, H.; Contreras, R.A.; Pizarro, M.; Cortes-Antiquera, R.; Zuniga, G.E. ; Grindel, A.; Hübenthal, U.; Brenden, H.; Grether-Beck, S.; Vielhaber, G.; Johncock, W.; Krutmann, J.; et al. Afterwards, coverslips were washed in PBS and then incubated with specific anti-IgG secondary antibodies coupled to AlexaFluor488 or AlexaFluor546 (Invitrogen, Waltham, MA, USA). Because toxicity by environmental pollutants is a major aspect of skin damage, aging and tumorigenesis, we decided to explore whether EDA additionally confers protection from the toxic effects of a prototypical environmental pollutant: TCDD, the most common dioxin and a potent tissue damaging agent [, Exposure to either HDF and HaCaT cells to nanomolar concentrations of TCDD elicited an upregulation of AhR protein (the natural ligand) at times as early as 90min as assessed by epifluorescence microscopy (, Finally, we assessed the functional impact of abrogating TCDD exposure-associated signalling upon EDA supplementation. Deschampsia antarctica and Colobanthus quitensis are the only vascular plants to have colonized the Maritime Antarctic, which is characterized by its permanently low temperature and frequent summer frosts. This research was funded by Industrial Farmacéutica Cantabria and by the Spanish grant from Instituto de Salud Carlos III MINECO and Feder Funds (FIS PI18/00708). Deschampsia antarctica (Edafence®, EDA), a natural aqueous extract, has shown keratinocyte and fibroblast cell protection effects against ultraviolet radiation and dioxin toxicity. ; Mataix, M.; Pérez-Davó, A.; Parrado, C.; González, S. Extract of Deschampsia antarctica (EDA) Prevents Dermal Cell Damage Induced by UV Radiation and 2,3,7,8-Tetrachlorodibenzo-p-dioxin. Rothhammer, V.; Quintana, F.J. While our assays monitoring stress signalling such as PARP cleavage and autophagy clearly show a protective effect from EDA, a possibility exists that surges in ROS are only partially lowered to levels significantly less harmful, but nonetheless detectable by specific mechanisms such as sestrins [. ; Visualization, A.Z. The activity of MMPs has been specifically associated with photoageing [. 2019; 20(6):1356. ; Bewersdorf, J.; Knight, K.L. Our dedicated information section provides allows you to learn more about MDPI. Hypoxic reactive oxygen species regulate the integrated stress response and cell survival. Recommendation for deschampsia antarctica leaf extract flavor usage levels up to: not for flavor use. Tigges, J.; Haarmann-Stemmann, T.; Vogel, C.F. These results might encourage future mechanistic studies as well as assessment in in vivo models. Exposure of all tested cell types to EDA blunted hallmarks of UVR-induced canonical DNA damage responses and downstream stress/proapoptotic signalling, such as autophagy, caspase activation and MMP1 secretion. Matrix-degrading metalloproteinases in photoaging. We do a Best of INCIDecoder email once a month with the most … Although the precise mechanisms at play will require extensive mechanistic characterization, beyond the scope of this report, it is clear that certain mechanisms sensing and transducing the impact of UVB on the cell are active despite the presence of EDA. Inhalation Toxicity: Not determined. Sci. Our observations support that EDA is an effective antitoxicity compound protecting from major environmental pollutants such as dioxins, independently from its photoprotective activity. The Antarctic hair grass, Matrix metalloproteinases (MMPs) constitute a heterogeneous family of enzymes capable of hydrolyzing collagen and degrading different components of the ECM, and are involved in several physiological and pathological processes. : a new player in autophagy and tumor cell growth salinity, solar irradiation and oxygen,.
