Ionizing Radiation Induced micro RNA Expression Alterations in Human Peripheral Blood Mononuclear Cells

ABSTRACT: Ionizing Radition is known to cause cell damage. Human peripheral blood mononuclear cells have long been used to study radiation induced gene expression profiling. Whithin this study we evaluated gene and microRNA expression alterations of human PBMC irradiated with 60 Gy g-ray. Cells were cultured for 2, 4 and 20h after irradiation before RNA was isolated and Agilent Human microRNA Microarrays was performed.

Ionizing Radiation Induced micro RNA Expression Alterations in Human Peripheral Blood Mononuclear Cells

Project description:Ionizing Radition is known to cause cell damage. Human peripheral blood mononuclear cells have long been used to study radiation induced gene expression profiling. Whithin this study we evaluated gene and microRNA expression alterations of human PBMC irradiated with 60 Gy g-ray. Cells were cultured for 2, 4 and 20h after irradiation before RNA was isolated and Agilent Human microRNA Microarrays was performed. Radiation induced gene expression in human peripheral blood mononuclear cells were measured at 2, 4 and 20 hours after exposure to doses of 60 Gy g-rays. Non radiated cell of each donor and time point were used as contol cells. Four independent experiments were performed at each time (2, 4, or 20 hours and 0 h - only 1 sample per donor) using 4 different donors.

Ionizing Radiation Induced Gene Expression Alterations in Human Peripheral Blood Mononuclear Cells

Project description:Ionizing Radition is known to cause cell damage. Human peripheral blood mononuclear cells have long been used to study radiation induced gene expression profiling. Within this study we evaluated gene and microRNA expression alterations of human PBMC irradiated with 60 Gy g-ray. Cells were cultured for 2, 4 and 20h after irradiation before RNA was isolated and Agilent whole human GenomeOligo Microarray was performed. Radiation induced gene expression in human peripheral blood mononuclear cells were measured at 2, 4 and 20 hours after exposure to doses of 60 Gy g-rays. Non radiated cell of each donor and time point were used as contol cells. Four independent experiments were performed at each time (2, 4, or 20 hours and 0 h - only 1 sample per donor) using 4 different donors.

ATM Requirement in Gene Expression Responses to Ionizing Radiation in Human Lymphoblasts and Fibroblasts

Project description:Investigation of ATM-dependent and dose-dependent, or -independent, responses were examined in human lymphoblast cells 6 hr following exposure to either 1 or 5 Gy ionizing radiation. Human lymphoblast cells from "apparently healthy" individuals and individuals with Ataxia telangiectasia were exposed to 1 Gy or 5 Gy ionizing radiation. Gene expression responses 6 hr following IR were examined. Untreated samples were hybridized together with their matched treated samples.

Gene expression profile of mouse Lewis lung carcinoma cell line treated with single or fractionated ionizing radiation doses

Project description:Radiotherapy is one of the most common therapies for cancer. Approximately half of all cancer patients will receive radiotherapy at some point during treatment. Consequences of IR treatment are dose dependent and different sensitivity to IR of various types of cells is well established. To reduce the damage of IR to most sensitive cells of normal (noncancerous) tissue radiotherapy is administered as fractionated dose treatment applying radiation in ~2 Gy fractions every 24 hours, 5 times per week. However, during the therapy intrinsic and acquired tumor radioresistance may result in treatment failures. Comprehensive mechanisms of the resistance to irradiation as well as mechanisms of cellular response to fractionated dose IR remain unclear. Therefore, in the present study we evaluated global gene expression changes in murine Lewis lung carcinoma LLC1 cells following X-ray irradiation of single 2 Gy or 10 Gy and 2 Gy x 5 fractionated doses. Total RNA was harvested from mouse Lewis lung carcinoma cells 4h after treatment of single (2 Gy or 10 Gy) or fractionated (5x2 Gy) ionizing radiation dose.

microRNA expression data from AG 1522 human fibroblasts post X-ray radiation

Project description:Radioadaptive response (RAR) in mammalian cells refers to the phenomenon where a low-dose ionizing irradiation alters the gene expression profiles, and protects the cells from the detrimental effects of a subsequent high dose exposure. We focused on microRNA microarray studies, and aimed to characterize the transcriptome for RAR in AG 1522 human skin fibroblasts and to examine the functional regulatory networks at the genetic level. AG 1522 cells were exposed at a specific time point to a challenging dose of 2 Gy in the RAR group, or a priming dose of 5 cGy in the low-dose group. We aimed to have a comprehensive investigation on the RAR induced in the AG 1522 human fibroblasts first exposed to 5 cGy (priming dose) and then followed by 2 Gy (challenge dose) of X-ray through comparisons to those cells which had only received a single 2 Gy dose.

Effects of Ionizing Radiation on Self Renewal and Pluripotency of Human Embryonic Stem Cells

Project description:Human embryonic stem cells (hESCs) present a novel platform for in vitro investigation of the early embryonic cellular response to ionizing radiation. Thus far, no study has analyzed the genome-wide transcriptional response to ionizing radiation in hESCs. In this study, we use Agilent microarrays to analyze the global gene expression changes in H9 hESCs after low (0.4 Gy), medium (2 Gy), and high (4 Gy) dose irradiation. Undifferentiated H9 hESCs were cultured on Matrigel in feeder-free conditions, and exposed to ionizing radiation at the indicated dosage (or control) from a Cesium-137 irradiator. Total RNA was isolated 24 hours after irradiation in the same feeder-free culture conditions. Experiment was repeated three times for each group, yielding a total of 12 distinct samples.
