Project description:Transcriptional profiling of Schmidtea mediterranea planarians that have been amputated transversely and left to regenerate for different time points (UNIRR); the same experiment was performed on irradiated - neoblast depleted animals (IRR). The purpose of this experiment was to identify transcriptional changes that are induced within the first 12h following amputation. In order to distinguish between gene expression changes in the differentiated tissue and the neoblasts, a second set of time course data was created from irradiated animals

Project description:The planarian Dugesia japonica has amazing ability to regenerate a head from the anterior ends of the amputated stump with maintenance of the original anterior-posterior polarity. Although planarians present an attractive system for molecular investigation of regeneration and research has focused on clarifying the molecular mechanism of regeneration initiation in planarians, but proteomic studies are still in the early stages. Here, a global proteomics analysis of regenerating head fragments in planarians at 0h, 2h and 6h after amputation was performed using isobaric tags for relative and absolute quantitation (iTRAQ)-based quantitative proteomics coupled with LC-MS/MS strategy. Then the significantly changed proteins were identified. The correlation betwwen protein expression profiles and signaling pathways/biological processes was analyzed by bioinformatics and systems biology.

Project description:To understand the molecular mechanism underlying inflammatory reaction in vascular system post exposure to ionizing radiation, we carried out microarray analysis in HUVEC exposed with X-ray HUVEC were irradiated with X-ray (2.5 Gy) and then cultured for 6, 12, and 24 hr. Total RNA were extracted from the tissue by QIAGEN Rneasy mini kit.

Project description:CEA_SGF:E00006# This set of experiments was performed in order to identify radiation responsive genes. For this, differentiated cultures derived from a single donor were irradiated at either 1 cGy, 2 Gy or sham-irradiated at T0 and total RNA extracts were prepared at 6 time points post-irradiation. Irradiated samples for each dose were hybridized seperately with sham-irradiated samples at the same time point. Each time point for each individual dose was assessed with two independent dye-swap hybridizations. Keywords: time-course

Project description:In order to identified as candidate biomarkers for early diagonosis or as therapeutic targets in late damages of ionizing radiation, gene expression profile was analyzed in the peripheral blood of three 60Co γ-ray accidently-exposed persons. The results showed that there were 285 up-regulated and 446 down-regulated genes in irradiated samples compared with control samples. The large majority of those differentially expressed genes encode proteins that are associated with immune response, inflammation, cell structure, oxidative stress, neuro-hormone regulation, reproduction, susceptibility of psychiatric disorders, and transcriptional regulators. The expressions of IL3, KDR, CEACAM8 and OSM were validated by real-time RT-PCR method. The findings of our study should help us understanding the molecular mechanisms underlying the late effects of ionizing radiation and to develop better diagonostic and therapeutic strategies for those damages. Fresh blood samples were collected from three 60Coγ-Ray accidentally-exposed persons(3 years post irradiation) and three non-irradiated healthy donors. Leucocytes cells were isolated and total RNA was extracted. Four RNA samples, from three accidently-exposed persons and a RNA mixture extracted from a combination of three healthy donors` leucocytes (ratio 1:1:1, each 3.3×106 cells) in EL buffer, were subjected to Agilent gene expression microarray assay.

Project description:CEA_SGF:E00007# This set of experiments was made in order to perform time series analyses. RNAs from sham-irradiated cells at each time point were pooled together. We then hybridized sham-irradiated samples at each time point versus cDNAs obtained from the pooled RNA. Each time point was assessed with two independent dye-swap hybridizations.
