Project description:In order to study the gene expression profiles of monocyte and macrophages, we collected three type of cells and performed pair-wised comparison. It includes human peripheral blood monocyte (MONO), human peripheral blood monocyte derived macrophages treated with M-CSF (MACRO)and primary alveolar macrophages (BAL). All the experiments are performed comparing two of the three cell types from the same person (total 4 persons). Totally we got three set of microarray data, MONO/MACRO, MONO/BAL and MACRO/BAL with 4 biological replicates.
Project description:We found that radiation treatment enhanced the expression of H3K27me3 in glioblastoma. Thus, we asked whether radiation contributed to the increase of global genomic H3K27me3 occupancy in glioblastoma. The Chip-seq results in GL261 cells showed that irradiation led to the increase of H3K27me3 occupancy ±50kb within the transcription start sites (TSS), especially the promoter sites (peaks±2kb within TSS). Some pathways, in which H3K27me3 peaks significantly enriched, were found. Chip-seq was conducted for H3K27me3 in glioblastoma cell line GL261 when GL261 cells were treated with or without irradiation.
Project description:ChIP-seq of H3K27me3 in rat peripheral nerve was used to identify sites of polycomb repression associated with genes in Schwann cells, which constitute the majority of cells in peripheral nerve. H3K27me3 ChIP samples were prepared from rat sciatic nerve and then sequenced. Inputs for these ChIP samples have previously been submitted as samples GSM1541282 and GSM1541283 in Series GSE63103
Project description:The risk of sepsis is particularly high in neonates compared to older children and adults; however the reasons behind are incompletely understood. Macrophages are at the front line of the innate immune system and differentiate from monocytes after infiltrating the infected tissue. We studied transcriptional differences between cord blood-derived in vitro activated macrophages and adult peripheral blood derived in vitro actiavted macrophages. We used microarrays to detail the global programme of gene expression in cord blood derived M(IL-10) and M(IFN-γ) and in adult blood derived M(IL-10) and M(IFN-γ)macropahges
