Description
The gene expression of murine splenic myeloid derived suppressor cells treated with Tff2 is characterized. The motivation of the study originates in the fact that Gr1+Cd11b+ myeloid-derived suppressor cells (MDSCs), which resemble immature myeloid cells (IMCs), expand during cancer in response to inflammatory cytokines and accumulate in the spleen. MDSCs promote neoplastic progression through their suppression of anti-tumourigenic cytotoxic T-cells. MDSCs are also rapidly expanded following acute insults, but in cancer as opposed to acute inflammation, MDSCs persist. It is now recognized that a vagally-mediated, anti-inflammatory reflex arc promoting acetylcholine secretion by Cd4+ (Cd44hiSelllo) T cells, is necessary for a return to homeostasis after an acute insult. Failure of this restorative neural circuit might contribute to unabated procarcinogenic inflammation, with the chronic expansion of MDSCs driving carcinogenesis. Trefoil factor 2 (Tff2) is a secreted anti-inflammatory peptide produced by both epithelial cells and a small subset of splenic T cell.

Description
The tumor suppressor p53 regulates the differentiation of embryonic stem (ES) cells upon DNA damage. However, our understanding of this critical tumor suppressive role of p53 in ES cells is limited, mainly because of the lack of molecular mechanism. Here, we report a widespread cross-regulation of p53-mediated DNA damage signaling and the pluripotent gene network in ES cells using chromatin-immunoprecipitation assay-based sequencing (ChIP-seq) and gene expression microarray. Upon DNA damage, p53 directly regulates the transcription of 3644 genes (p<0.005) in mouse ES cells. Genome-wide analysis revealed a dramatic difference between the regulation of p53-activated and -repressed genes. p53 mainly regulates the promoter regions of activated genes, whereas the main regulatory regions for repressed genes reside in distal regions. Among p53-repressed genes, many are pluripotent transcription factors of ES cells, such as Oct4, Nanog, Sox2, Esrrb, c-Myc, n-Myc and Sall4. Strikingly, these transcriptional factors also directly regulate the transcription of the Trp53 gene, highlighting a previously under-estimated transcriptional regulation of p53 in ES cells. Therefore, p53 signaling and ES pluripotent transcriptional networks form an intertwined circuitry. Together, our results provide mechanistic insights into the crosstalk of p53-mediated DNA damage and ES cell "stemness" transcriptional gene networks and shed light on the tumor suppressive function of p53 in ES cells.
