DNA damage-induced differentiation of NSC

ABSTRACT: Murine ES-derived neural stem cells (NSC) were not irradiated (ctrl) or irradiated with 10Gy and cultured for 7 days (irr). The goal was to study the gene expression changes in NSC at d7 after irradiation.

DNA damage-induced differentiation of NSC

Project description:Murine ES-derived neural stem cells (NSC) were not irradiated (ctrl) or irradiated with 10Gy and cultured for 7 days (irr). The goal was to study the gene expression changes in NSC at d7 after irradiation. Total RNA was extracted from 4 ctrl and 4 irr samples (biological quadruplicates).

Transcript profiling of mouse 4T1 tumors grown in preirradiated vs. nonirradiated mammary tissue

Project description:The present study was designed to identify genes induced by irradiation in the 4T1 breast cancer model mimicking aggressive local relapse after radiotherapy. For this purpose, we obtained the transcriptomes of 4T1 tumors grown in either preirradiated (IRR+4T1) or non-irradiated (4T1) mammary tissue.

Transcriptome of Irradiated Microglia

Project description:Whole brain irradiation remains important in the management of brain tumors. Although necessary for improving survival outcomes, cranial irradiation also results in cognitive decline in long-term survivors. A chronic inflammatory state characterized by microglial activation has been implicated in radiation-induced brain injury, and here we present a comprehensive transcriptional profile of irradiated microglia. Fluorescence-activated cell sorting (FACS) was used to isolate CD11b+ microglia from the hippocampi of C57BL/6 and Balb/c mice 1 month after 10Gy cranial irradiation. Affymetrix gene expression profiles were evaluated using linear modeling and rank product analyses. A conserved signature of irradiation was identified across strains, and gene set enrichment analysis was employed to functionally compare our signature to publically available mouse and human datasets.

NSC-derived exosomes enhance therapeutic effects of NSC transplantation on cerebral ischemia in mice

Project description:Transplantation of neural stem cells (NSCs) has been proved to promote functional rehabilitation of brain lesions including ischemic stroke. However, the therapeutic effects of NSC transplantation is limited by the low survival and differentiation rates of NSCs due to the harsh environment in the brain after ischemic stroke. Here, we employed NSCs derived from human induced pluripotent stem cells (iPSCs) together with exosomes extracted from NSCs to treat cerebral ischemia induced by middle cerebral artery occlusion/reperfusion (MCAO/R) in mice. The results showed that NSC-derived exosomes significantly reduced the inflammatory response, alleviated oxidative stress after NSC transplantation, and facilitated NSCs differentiation in vivo. The combination of NSCs with exosomes ameliorated the injury of brain tissue including cerebral infarct, neuronal death and glial scarring, and promoted the motor function recovery. To explore the underlying mechanisms, we analyzed the miRNA profiles of NSC-derived exosomes and the potential downstream genes. Our study provided the rationale for the clinical application of NSC-derived exosomes as a supportive adjuvant for NSC transplantation after stroke.

Ionizing radiation induced hair and skin damage

Project description:Skin samples from back region and footpads were analyzed in 8-10 week old mice. For back skin, the hair was plucked in order to induce active growing phase(anagen). After 9 days, the mice were irradiated for 5Gy IR. Krt17 knock out, p53 knock out, and wild type mice were compared. Samples were taken at time 0 (control), 6h, and 24h post-irradiation. For footpad skin, the mice were irradiated for 40 Gy IR. Krt17 knock out and wild type mice were compared. Samples were taken at time 0 (control), 3 d, 6 d, 9 d post-irradiation.

Expression profile of Ceacam1 downstream genes in NSC and NSCL61

Project description:To identify Ceacam1 downstream factors, we compared gene expressions between NSCs and Ceacam1L-expressing NSC and between NSCL61 and Ceacam1shRNA-expressing NSCL61. We established Ceacam1L-expressing NSC and Ceacam1shRNA-expressing NSCL61s. We think that genes, which are differently expressed between NSC and Ceacam1L-NSC, and between NSCL61 and Ceacam1shRNA-NSCL61, are the Ceacam1 downstream factors.

Microarray analysis of MCF7 cells treated with NSC 59687 (Oxyphenisatin Acetate)

Project description:NSC 59687 (oxyphenisatin acetate) is a novel anti-cancer agent with selectivity for breast and ovarian cell lines To elucidate the transcripts differentially regulated following treatment with Oxyphenisatin acetate (NSC 59687) MCF7 cells were treated with 10 microM NSC 59687 for 24 hours followed by RNA extraction, cDNA synthesis and microarray analysis using Affymetrix huU133 plus 2.0 arrays
