Transcriptomes of human trophoblast cell lines

Gene expression in undifferentiated or cyclic adenosine monophosphate-exposed BeWo trophoblast cells

Project description:BeWo trophoblast cells differentiate in response to expsure to cyclic adenosine monophosphate (cAMP) analogs. Differentiation includes syncytialization (fusion) and hormonogenesis. The goal of this study was to globally determine transcripts differentially expressed in BeWo trophoblast cells following a 24-h exposure to 250 uM 8-bromo-cAMP. 3 replicates undifferentiated BeWo trophoblast cells; and 3 replicates BeWo trophoblast cells treated with 250 uM 8-Br-cAMP for 24 h.

Gene expression profiles of trophoblast cell lines

Project description:Invasive extravillous trophoblasts (EVTs) of the human placenta are critically involved in successful pregnancy outcome since they remodel the uterine spiral arteries to increase blood flow and oxygen delivery to the placenta and the developing fetus. To gain more insights into their biological role different primary cell culture models are commonly utilised. However, access to early placental tissue may be limited and primary trophoblasts rapidly cease proliferation in vitro impairing genetic manipulation. Hence, trophoblastic cell lines have been widely used as surrogates to study EVT function. Although the cell lines share some molecular marker expression with their primary counterpart, it is unknown to what extent they recapture the invasive phenotype of EVT. Therefore, we here report the first thorough GeneChip analyses of SGHPL-5, HTR-8/SVneo, BeWo, JEG-3 and the novel ACH-3P trophoblast cells in comparison to previously analysed primary villous cytrophoblasts and extravillous trophoblasts. To identify EVT-specific gene expression signatures in trophoblast cell lines, we calcuted differentially expressed genes between pre-defined groups based on the distinct origins of the five trophoblast cell lines under investigation. Comparison 1 comprised EVT, HTR-8/Svneo and SGHPL-5 vs choriocarcinoma cells (ACH-3P, BeWo, JEG-3). Comparison 2 comprised EVT, ACH-3P, BeWo, JEG-3 vs extravillous trophoblast cell lines (HTR-8/SVneo, SGHPL-5).

ZEB2 protects the heart from ischemic damage

Project description:infarct size and subsequent deterioration in function. The identification of factors that enhance cardiac repair by the restoration of the vascular network is, therefore, of great significance. Here, we show that the transcription factor Zinc finger E-box-binding homeobox 2 (ZEB2) is increased in stressed cardiomyocytes and induces a cardioprotective cross-talk between cardiomyocytes and endothelial cells to enhance angiogenesis after ischemia. Single-cell sequencing indicates ZEB2 to be enriched in injured cardiomyocytes. Cardiomyocyte-specific deletion of ZEB2 results in impaired cardiac contractility and infarct healing post-myocardial infarction (post-MI), while cardiomyocyte-specific ZEB2 overexpression improves cardiomyocyte survival and cardiac function. We identified Thymosin 4 (TMSB4) and Prothymosin (PTMA) as main paracrine factors released from cardiomyocytes to stimulate angiogenesis by enhancing endothelial cell migration, and whose regulation is validated in our in vivo models. Therapeutic delivery of ZEB2 to cardiomyocytes in the infarcted heart induces the expression of TMSB4 and PTMA, which enhances angiogenesis and prevents cardiac dysfunction. These findings reveal ZEB2 as a beneficial factor during ischemic injury, which may hold promise for the identification of new therapies.

Identification of ZEB2 binding sites in Hepatocellular Carcinoma Cell Line SNU398

Project description:ZEB2, a member of the ZEB family of EMT inducers, is involved in cellular proliferation, senescence, and invasion in most of the human cancers. However, genes regulated by ZEB2 in hepatocellular carcinoma (HCC) are not identified so far. Hence, we conducted a ChIP-Seq study in high ZEB2 expressing HCC cell line SNU398 by using a homemade anti-ZEB2 antibody (clone 6E5).
