Project description:Both leukemia inhibitory factor (LIF) and interleukin-6 (IL-6) increase the invasiveness of JEG-3 and HTR-8/SVneo cells. This study examines the effect of LIF and IL-6 on gene expression in trophoblastic cell models viz. JEG-3 and HTR-8/SVneo cells to decipher the molecular basis of the increase in invasiveness.

This study examines the effect of LIF and IL-6 on gene expression in trophoblastic cell models viz. JEG-3 and HTR-8/SVneo cells to decipher the molecular basis of the increase in invasiveness. JEG-3 and HTR-8/Svneo cells were stimulated with LIF (50 ng/ml) and IL-6 (100 ng/ml) for 24 h in plain medium keeping untreated cells as a control. After 24 h of stimulation, total RNA was isolated from these cells and used for microarray experiments. These experiments were performed once.
Project description:IL-11 increases the invasiveness of JEG-3 cells while, reduces the invasiveness of HTR-8/SVneo cells. This study examines the effect of IL-11 on gene expression in trophobalstic cell models viz. JEG-3 and HTR-8/SVneo cells to resolve the controversies associated with the IL-11 mediated regulation of the invasiveness of these two cell lines. JEG-3 and HTR-8/Svneo cells were stimulated with IL-11 (200 ng/ml) for 24 h in pain medium keeping un-treated cells as control. After 24 h of stimulation, total RNA was isolated from these cells and used for the microarray experiments. These experiments were performed once.

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).
