deschampsia antarctica extract

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. The RCSB PDB also provides a variety of tools and resources. See further details. A primer on caspase mechanisms. The skin is an organ specialized as a first major barrier against ionizing radiations and chemical damage.

Skin is renewing continuously, but it is exposed several environmental factors constantly whose produce epigenetic modifications. Ramirez, M.L.G. Cell viability in HaCaT and HDF cells after different treatments was determined by MTT assay. Natural extracts and compounds are particularly interesting, because they have typically evolved low toxicity and high anti-stressor activities, and very often combine multiple synergistic effects such as antioxidant and enhancer of tissue repair.

Pérez-Torres, E.; García, A.; Dinamarca, J.; Alberdi, M.; Gutiérrez, A.; Gidekel, M.; Ivanov, A.G.; Hüner, N.P. Author to whom correspondence should be addressed. Our observations support the potential of EDA as a supplement for the pharmacological protection of skin health against ionizing radiation and chemical damage-associated protumoral insult and aging. Data are represented as the mean standard deviation (SD) of at least three independent experiments. We want to acknowledge Pablo Delgado from the Department of Biology, Faculty of Sciences, Universidad Autónoma (Madrid, Spain) for helping us in the methodology of the work. MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. Ultraviolet ionizing radiation (UVR) constitutes ~10% of total sunlight output, and is the most prominent causative factor for skin cancers (reviewed in open online resources: In. Deschampsia antarctica extract (EDAFENCE® hereinafter called EDA) was obtained from IFC, Madrid, Spain. ; Martinho, H.; Daghastanli, N.; Nantes, I.L. J. Mol. Find support for a specific problem on the support section of our website. Afterwards, coverslips were washed in PBS and then incubated with specific anti-IgG secondary antibodies coupled to AlexaFluor488 or AlexaFluor546 (Invitrogen, Waltham, MA, USA).

Please note that many of the page functionalities won't work as expected without javascript enabled. For irradiation, cell culture medium was replaced by PBS in all cases. Samples were collected from Antarctica and maintained in vitro culture during 2 years. To understand how the plants survive freezing temperatures year-round, antifreeze activity was assayed in apoplastic extracts obtained from both non-acclimated and cold … 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. Taken together, our observations support that EDA is a non-toxic compound that confers protection from UV-induced damage of cell structures and downstream signalling, and improves homeostasis and survival of both HDF cells and keratinocytes exposed to ionizing radiation. ; Xiong, F.S. Both percentages of positive cells and mean fluorescent intensity for specific antibodies were determined by using the Image J analysis software. Rigel, D.S. Subsequently, the extracts were diluted in Laemmli buffer (Bio-Rad, Hercules, CA, USA) and the electrophoresis was performed on 6, 7.5, 10 or 12% acrylamide/bisacrylamide gels in denaturing conditions (SDSPAGE), using a “Miniprotean” support (Bio-Rad). 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). 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). Differences were considered to be significant when. 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.

In summary, we contribute evidence that EDA displays significant protective roles in both fibroblasts and keratinocytes in the face of both UV radiation and prototypical dioxin toxicity, while having little intrinsic impact on cell proliferation and homeostasis. The present disclosure provides a novel antineoplastic extract obtained from Deschampsia antarctica plant. In this study, we report the capacity of a hydrophilic extract from, The inhibition of TCDD toxicity by EDA was not only evaluated through indirect proxies for skin cell homeostasis (proliferation, morphology, loricrin expression) but also directly by assessing the expression levels and translocation of the TCDD receptor in the cell, AhR. The statements, opinions and data contained in the journals are solely These protective effects were independent from modulation of cell cycle progression. For the detection of nuclear AhR and laminin B (Dallas, TX, USA), the extract of the cytoplasmic and nuclear proteins was performed separately with the Nuclear Extraction Kit (Merk) according to manufacturer’s instructions.

Dioxins, the aryl hydrocarbon receptor and the central regulation of energy balance. Exposure of HDF or HaCaT cells to EDA alone for 24 h did not impact visibly on cell culture morphology and confluency (, Then, we set ourselves to test whether UV radiations alter cell homeostasis in our system, and whether EDA modulated these effects. High throughput sequencing showed that up to 92% of DNA reads, and 68% of RNA reads, in soils from the islands were accounted for by the fungus. An extract from the plant Deschampsia antarctica protects fibroblasts from senescence induced by hydrogen peroxide. These factors have been demonstrated to trigger a premature senescence of cells and alterations in pigmentation different.

Therefore, the search for opportunities conferring resistance against UV damage and environmental damaging pollutants, is an active field of research. This plant lives under high salinity, solar irradiation and oxygen concentration, low temperature and extreme dryness [12]. Cell proliferation in HaCaT and HDF cells after different treatments was measured by crystal violet staining (0.2% (.
