Human and murine studies showed that granulocyte macrophage colony-stimulating factor (GM-CSF) exerts beneficial effects in intestinal inflammation. To explore whether GM-CSF mediates its effects via monocytes, we analyzed effects of GM-CSF on monocytes in vitro and assessed the immunomodulatory potential of GM-CSF-activated monocytes (GMaM). We used microarray technology and functional assays to characterize GMaM in vitro and used a mouse model of colitis to study GMaM functions in vivo.
Reprogramming of monocytes by GM-CSF contributes to regulatory immune functions during intestinal inflammation.

View SamplesOncogene-induced senescence (OIS), a terminal cell cycle block countering (pre)neoplastic lesions, is characterised on the molecular level by trimethylated histone H3 lysine 9 (h3K9me3), a transcriptionally repressive chromatin mark linked to silencing of S-phase-promoting genes. Whether H3K9-governed chromatin remodelling influences anticancer treatment-induced senescence (TIS) and whether functional control of this mark impacts on treatment outcome is not known. We used global gene expression profiling by microarrays to gain insight into the molecular responses of Emu-myc; Suv39h1-/- B-cell lymphoma cells to senescence-inducing anticancer agent Adriamycin (ADR).
