Gene expression in human umbilical vein endothelial cells (HUVEC) was investigated by microarray analysis after 4 h infection with S. aureus isolated from healthy nasal carriers (n=5) and from blood (n=5) of septic patients. All bacterial isolates were spa-typed and characterized with a DNA microarray to determine the presence of virulence genes.
Staphylococcus aureus isolates from blood and anterior nares induce similar innate immune responses in endothelial cells.

View SamplesThe regional specificity and timing of gene activation following chemotherapy, and how this relates to subsequent mucositis development is currently unknown. The aim of the study was therefore to determine the early time course of gene expression changes along the gastrointestinal tract (GIT) of the DA rat following irinotecan treatment, so as to provide an insight into the genetic component of mucositis.
Gene expression analysis of multiple gastrointestinal regions reveals activation of common cell regulatory pathways following cytotoxic chemotherapy.

View SamplesSFMBT1 is a poorly characterized mammalian MBT domain-containing protein homologous to Drosophila SFMBT, a Polycomb group protein involved in epigenetic regulation of gene expression. Here, we show that SFMBT1 regulates transcription in somatic cells and during spermatogenesis through the formation of a stable complex with LSD1 and CoREST. When bound to its gene targets, SFMBT1 recruits its associated proteins and causes chromatin compaction and transcriptional repression. SFMBT1, LSD1, and CoREST share a large fraction of target genes including those encoding replication-dependent histones. Simultaneous occupancy of histone genes by SFMBT1, LSD1, and CoREST is regulated during the cell cycle and correlates with the loss of RNA polymerase II at these promoters during G2, M, and G1. The interplay between the repressive SFMBT1–LSD1–CoREST complex and RNA polymerase II contributes to the timely transcriptional regulation of histone genes in human cells. SFMBT1, LSD1, and CoREST also form a stable complex in germ cells and their chromatin binding activity is regulated during spermatogenesis. Overall design: RNA-seq in HeLaS3 cells ctrl compared to triple knockdown for SFMBT1, CoREST, and LSD1
SFMBT1 functions with LSD1 to regulate expression of canonical histone genes and chromatin-related factors.
