Single-cell analysis reveals the progress in skin repair after radiation in rats.

ABSTRACT: This study aims to compare the cell heterogeneity and mRNA expression between irradiated and non-irradiated rat skin tissues at the single cell level. In this study, the skin was isolated from rats with radiation or non-irradiated rats. Male Sprague Dawley (SD) rats (6 weeks of age) were used. For irradiation, the hair on the gluteal region of the rats was shaved using a razor. The animals were immobilized using adhesive tape on a plastic plate to minimize motion during radiation exposure. A 3-cm-thick piece of lead was used to shield the animals and localize the radiation field (3-4 cm). Irradiation was performed on the treatment area at a dose rate of 1000 cGy/min using a 6-MeV electron beam accelerator. Irradiated skin was taken on day 7, 14, 28 and 60 for RNA-seq, respectively. The control group of skin were collected from four rats without radiation and mixed for RNA-seq.

Transcription profiling of prostate tumor cell line AT1 inocculated into rats and then subjected to carbon ion or photon radiation

Project description:In the present study approximately 1 to 2 mm3 prostate tumor AT1 was inoculated subcutaneously in the right hind leg of adult male Copenhagen rats. When the tumor diameter exceeded 15 mm, tumors of 5 and 4 rats were irradiated with carbon ion radiation of 37 or 16Gy respectively. Tumors of 5 other rats were irradiated with photon radiation of 37Gy. One animal irradiated with 37 Gy carbon ion radiation and one animal irradiated with photon radiation was sacrificed 12h, 30h, 72h, 7d and 14d after irradiation respectively. One animal irradiated with 16 Gy photon radiation was sacrificed 12h, 60h, 7d and 14d after irradiation respectively. Non-irradiated animals were sacrificed at 60h time point. Tumors were dissected and frozen in liquid nitrogen immediately. Total RNA from tumor material was isolated using the NucleoSpin RNA L kit (#740962.20, Macherey-Nagel). Differential gene expression analysis was performed on the Agilent whole rat genome Oligo Microarray (44k) platform by comparative two dye hybridisation with dye-swaps.

Genome-wide Transcriptional Profiling of Skin and Dorsal Root Ganglia after Ultraviolet-B-Induced Inflammation

Project description:Ultraviolet-B (UVB) irradiation of the skin was performed on rat (skin and DRG) and human (skin) tissue. The resulting changes in gene expression were then profiled by using RNA-seq to compare gene expression between irradiated and non-irradiated samples Poly(A) selected RNA was sequenced for 5 irradiated and 4 non-irradiated humans (skin), and for 6 irradiated and 6 non-irradiated rats (DRG and skin)

MiRNAs expression in supernatant after ultraviolet irradiation

Project description:To investigate the mechanism of radiation induced bystander effect, we explored miRNAs expression in supernatant of human skin fibroblasts after culturing for 24h post UV irradiation. Primary human skin fibroblasts were obtained from healthy volunteers by means of a foreskin circumcision. Human skin fibroblasts was irradiated with 20J/cm2 UVA or 60mJ/cm2 UVB. Expression of miRNAs were tested by microarray between radiation and control samples.

Murine microenvironment metaprofiles associate with human cancer etiology and intrinsic subtypes

Project description:We developed a mouse model that captures radiation effects on host biology by transplanting unirradiated Trp53 null mammary tissue to sham or irradiated hosts. Gene expression profiles of tumors that arose in irradiated mice are distinct from those that arose in naM-CM-/ve hosts. Host irradiation induces a metaprofile consisting of gene modules representing stem cells, cell motility, macrophages and autophagy. Human orthologs of the host irradiation metaprofile discriminated between radiation-preceded and sporadic human thyroid cancers. An irradiated host centroid was strongly associated with estrogen receptor negative breast cancer. When applied to sporadic human breast cancers, the irradiated host metaprofile strongly associated with basal-like and claudin-low breast cancer intrinsic subtypes. Comparing host irradiation in the context of TGFM-NM-2 levels showed that inflammation was robustly associated with claudin-low tumors. The association of the irradiated host metaprofiles with estrogen receptor negative status and claudin-low subtype suggests that host processes similar to those induced by radiation underlie sporadic cancers. Total RNA was extracted from mammary tumors derived from transplantations of non-irradiated p53null mammary fragments into irradiated hosts. We analyized a total of 32 p53null tumors from irradiated wild type mice: 9 from sham-irradiated hosts, and 23 from irradiated hosts. We also analyzed 24 tumors from irradiated TGFb1 heterozygote hosts: 6 from sham-irradiated hosts, and 18 from irradiated hosts.

Erbb2 regulates inflammation and proliferation in the skin after ultraviolet irradiation.

Project description:Exposure to ultraviolet (UV) irradiation is the major cause of nonmelanoma skin cancer, the most common form of cancer in the United States. UV irradiation has a variety of effects on the skin associated with carcinogenesis, including DNA damage and effects on signal transduction. The alterations in signaling caused by UV regulate inflammation, cell proliferation, and apoptosis. UV also activates the orphan receptor tyrosine kinase and proto-oncogene Erbb2 (HER2/neu). In this study, we demonstrate that the UV-induced activation of Erbb2 regulates the response of the skin to UV. Inhibition or knockdown of Erbb2 before UV irradiation suppressed cell proliferation, cell survival, and inflammation after UV. In addition, Erbb2 was necessary for the UV-induced expression of numerous proinflammatory genes that are regulated by the transcription factors nuclear factor-kappaB and Comp1, including interleukin-1beta, prostaglandin-endoperoxidase synthase 2 (Cyclooxygenase-2), and multiple chemokines. These results reveal the influence of Erbb2 on the UV response and suggest a role for Erbb2 in UV-induced pathologies such as skin cancer. Keywords: time course, ultraviolet irradiation, UV, erbB2, mouse skin The dorsal skin of adult female CD-1 mice was clipped one day before treatment and shaved on the day of treatment. DMSO or 4 mg AG825 dissolved in DMSO was applied topically to the shaved back of the mice 2 h prior to exposure to 10 kJ/m^2 UV or sham irradiation. The UV dose was approximately 30% UVA, 70% UVB and <1% UVC, with a total output of 470 uW/cm^2. Flash frozen skin was removed and total RNA expracted with TRIzol reagent (Invitrogen) and further purified with an RNeasy kit (Qiagen). Amplification, reverse-transcription, biotinylation, and hybridization were all carried out under standard conditions and procedures recommended by the manufacturer.

Transcription profiling of mouse lung and skin from A/J, C57BL/6J and C3H/HeMs strains treated with gamma rays to identify radiation-induced gene expression.

Project description:Gene expression profiling was used to identify genes that display radiation-induced transcriptional change over mouse strain and tissue differences. Experiment Overall Design: Inbred A/J, C57BL/6J and C3H/HeMs female mice were irradiated by gamma-rays as local irradiation in single doses to the thorax or hind leg. The animals were sacrificed at 1, 12 and 72 hours after irradiation. Non-irradiated mice served as the controls. The lungs and skin were dissected and used for expression analysis. Each sample including non-irradiated control was hybridized with global control that derived from mixture of commercially available total RNA from ten organs.

Transcriptomic analysis of early response of rat brain orthotopic tumors after synchrotron microbeam irradiation (MRT)

Project description:The aim of this study was to identify the transcriptomic response 6 hours after the MRT irradiation, in normal brain tissue (11 samples) and in glioma tissue (11 samples), in rat. The orthotopic tumor-bearing rats were either treated with MRT radiation (six MRT-tumors), or untreated (five No irradiated tumors). The contralateral half hemisphere without tumor received the MRT treatment for six rats (6 MRT-Contralateral samples) and no irradiation for five rats (5 Untreated contralateral samples). Six hours after treatment, the tumors and their controlateral regions were resected and analysed for transcriptomic response.
