Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Dendritic cells (DCs) are professional antigen-presenting cells whose activity is intrinsically linked to the microenvironment. Hypoxia is a condition of low oxygen tension occurring in inflammatory tissues that creates a special microenvironment conditioning cell physiology. We studied the effects of hypoxia on the differentiation of human monocytes into DCs and maturation into mature DCs. Mature DCs were differentiated in vitro from human monocytes under normoxic or hypoxic conditions and the gene expression profile was determined.
Publication Title
Hypoxia modulates the gene expression profile of immunoregulatory receptors in human mature dendritic cells: identification of TREM-1 as a novel hypoxic marker in vitro and in vivo.

- Affymetrix HT HG-U133+ PM Array Plate (hthgu133pluspm)
Description
Here we studied the effects of anticonvulsant drug exposure in a human embryonic stem cell (hESC) based neuro- developmental toxicity test (hESTn). During neural differentiation the cells were exposed, for either 1 or 7 days, to non-cytotoxic concentration ranges of valproic acid (VPA) or carbamazepine (CBZ), anti-epileptic drugs known to cause neurodevelopmental toxicity.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
About 10% of Down syndrome (DS) infants are born with a myeloproliferative disorder (DS-TMD) that spontaneously resolves within the first few months of life. About 20-30% of these infants subsequently develop acute megakaryoblastic leukemia (DS-AMKL). In order to understand differences that may exist between fetal and bone marrow megakaryocyte progenitor cell populations we flow sorted megakaryocyte progenitor cells and performed microarray expression analysis.

Description
Evaluation of the role of RIP4 in lung adenocarcinoma revealed that RIP4 inhibits STAT3 signaling in vitro and in vivo. Repression of RIP4 enhanced STAT3 signaling activation in KRAS LSL/G12D/wt; p53flox/flox murine tumors. This promoted cancer dedifferentiation through ECM remodeling

Description
Epigenetic regulation is based upon a network of complexes that modulate the chromatin character and structure of the genome to impact gene expression, cell fate, and development. Thus, epigenetic modulators represent novel therapeutic targets to treat a range of diseases including malignancies. Infectious pathogens such as herpesviruses are also regulated by cellular epigenetic machinery, and epigenetic therapeutics represent a novel approach to control infection, persistence, and the resulting recurrent disease. The histone methyltransferases EZH2 and EZH1 (EZH2/1) are epigenetic repressors that suppress gene transcription via propagation of repressive H3K27me3 enriched chromatin domains. However, while EZH2/1 are implicated in repression of herpesviral gene expression, inhibitors of these enzymes suppressed HSV primary infection in vitro and in vivo. Furthermore, these compounds blocked lytic viral replication following induction of HSV reactivation in latently infected sensory ganglia. Suppression correlated with the induction of multiple inflammatory, stress, and anti-pathogen pathways as well as enhanced recruitment of immune cells to in vivo infection sites. Importantly, EZH2/1 inhibitors induced a cellular antiviral state that also suppressed infection with DNA (hCMV, Adenovirus) and RNA (Zika virus) viruses. Thus, EZH2/1 inhibitors have considerable potential as general antivirals through activation of cellular antiviral and immune responses.
