Low-dose/Low-dose-rate (LDR) gamma-radiation using 57Co plates (0.04 Gy) was delivered whole-body to mature 6-month old female C57BL/6 mice to simulate the radiation component. Anti-orthostatic tail suspension was used to model the unloading fluid shift and physiological stress aspects of the microgravity component. Mice were hindlimb suspended and/or irradiated for 21 days. Tissues were collected at 7 days 1 4 and 9 months following simulated microgravity. Herein we proposed to use omics-based molecular phenotyping approach for identification and characterization of genomic signatures in multiple organ system associated with low-dose radiation and simulated microgravity.", "distribution": [{"@type": "dcat:Distribution", "description": "GeneLab Study Page", "downloadURL": "https://genelab-data.ndc.nasa.gov/genelab/accession/GLDS-202", "format": "HTML", "mediaType": "text/html", "title": "Low dose (0.04 Gy) irradiation (LDR) and hindlimb unloading (HLU) microgravity in mice: brain transcriptomic and epigenomic data"}], "identifier": "nasa_genelab_GLDS-202_3mby-5d3m", "issued": "2021-05-21", "keyword": ["data-collection", "data-transformation", "dna-sequencing-library-construction", "genelab-rnaseq-data-processing-protocol", "hindlimb-unloading", "ionizing-radiation", "labeling", "nucleic-acid-extraction", "nucleic-acid-hybridization", "nucleic-acid-sequencing", "rna-sequencing-library-construction", "sample-collection", "spike-in-protocol", "time-of-sample-collection-after-treatment", "treatment-protocol"], "landingPage": "https://data.nasa.gov/dataset/low-dose-0-04-gy-irradiation-ldr-and-hindlimb-unloading-hlu-microgravity-in-mice-brain-tra", "license": "http://www.usa.gov/publicdomain/label/1.0/", "modified": "2025-04-23", "programCode": ["026:005"], "publisher": {"@type": "org:Organization", "name": "National Aeronautics and Space Administration"}, "theme": ["Earth Science"], "title": "Low dose (0.04 Gy) irradiation (LDR) and hindlimb unloading (HLU) microgravity in mice: brain transcriptomic and epigenomic data"}
