Description
Primary liver cancer represents a major health problem. It comprises hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC), which differ markedly with regards to their morphology, metastatic potential and therapy response. Yet, molecular actors and tissue context that commit transformed hepatic cells towards HCC or ICC are largely unknown. Here, we report that the hepatic microenvironment epigenetically shapes lineage commitment in mosaic mouse models of liver tumourigenesis. While a necroptosis associated hepatic cytokine microenvironment determines ICC outgrowth from oncogenically transformed hepatocytes, hepatocytes harbouring identical oncogenic drivers give rise to HCC if surrounded by apoptotic hepatocytes. Epigenome and transcriptome profiling of murine HCC and ICC singled out Tbx3 and Prdm5 as major microenvironment-dependent and epigenetically regulated lineage commitment factors, a function conserved in humans. Together, our study provides unprecedented insights into lineage commitment in liver tumourigenesis and explains molecularly why common liver damaging risk factors can either lead to HCC or ICC.

Description
Senescence can be transmitted in a paracrine way from cells undergoing Oncogene Induced Senescence (OIS) to nave normal cells. We define this phenomenon as paracrine senescence

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Natural killer (NK) cells are lymphocytes that participate in immune responses through their cytotoxic activity and secretion of cytokines and chemokines. They can be activated by interaction with ligands on target cells or by soluble mediators such as cytokines. In addition, soluble HLA-G, a major histocompatibility complex molecule secreted by fetal trophoblast cells during early pregnancy, stimulates resting NK cells to secrete proinflammatory and proangiogenic factors. Human NK cells are abundant in uterus, where they remain after implantation. Soluble HLA-G is endocytosed into early endosomes of NK cells where its receptor, CD158d, initiates a signaling cascade through DNA-PKcs, Akt and NF-kB3. The physiological relevance of this endosomal signaling pathway, and how the fate and function of NK cells during early pregnancy is regulated, is unknown. Here we show that soluble agonists of CD158d trigger DNA damage response signaling and p21 (CIP1/WAF1) expression to promote senescence in primary NK cells. CD158d engagement resulted in morphological alterations in cell size and shape, chromatin remodeling, and survival in the absence of proliferation, all hallmarks of senescence. Microarray analysis revealed a senescence signature of upregulated genes upon sustained activation through CD158d. The proinflammatory and proangiogenic factors secreted by these metabolically active NK cells are part of a senescence associated secretory phenotype (SASP) that promoted tissue remodeling and angiogenesis as assessed by functional readouts of vascular permeability and endothelial cell tube formation. We propose that ligand-induced senescence is a molecular switch for the sustained activation of NK cells in response to soluble HLA-G for the purpose of remodeling the maternal vasculature in early pregnancy.

- Affymetrix Drosophila Genome 2.0 Array (drosophila2)
Description
We conducted a genome-wide expression analysis of wild-type males using three cell populations isolated from mitotic, meiotic and post-meiotic phases of spermatogenesis in Drosophila melanogaster. Our approach was to directly isolate testis regions enriched with RNAs from each of the three specific germline phases.
Publication Title
Stage-specific expression profiling of Drosophila spermatogenesis suggests that meiotic sex chromosome inactivation drives genomic relocation of testis-expressed genes.
