Project description:Aim of this study was to identify miRNAs which are regulated by LIF in different trophoblastic cell lines Total RNA was reverse-transcribed, pre-amplified with miRNA-specific primers, and loaded into TaqMan Arrays. Quantitative real-time PCR was performed for 768 miRNAs. For each of two cards per sample (A and B), 9 ul of pre-amplified diluted sample was mixed with TaqMan reaction mix (Applied Biosystems) and loaded into miRNA TLDA cards (Applied Biosystems) by centrifugation. Cards were sealed, and qRT-PCR was performed with a real-time thermocycler (ABI-7900, Applied Biosystems) per manufacturer's recommendations.

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:To gain more insight in the expression and role of microRNAs in trophoblastic cells, we have assessed the miRNA expression pattern of four trophoblastic cell lines and have compared them with the miRNA signature of human isolated 3rd trimester cytotrophoblast cells. Total RNA was reverse-transcribed, pre-amplified with miRNA-specific primers, and loaded into TLDA cards. Quantitative real-time PCR was performed for 768 miRNAs. For each of two cards per sample (A and B), 9 ul of pre-amplified diluted sample was mixed with TaqMan reaction mix (Applied Biosystems) and loaded into miRNA TLDA cards (Applied Biosystems) by centrifugation. Cards were sealed, and qRT-PCR was performed at a real-time thermocycler (ABI-7900, Applied Biosystems) following the manufacturer's recommendations. MiRNA signatures of human primary 3rd trimester trophoblast cells were compared with those of four trophoblastic cell lines

Project description:Oncostatin M (OSM) and Leukemia Inhibitory Factor (LIF) signal within cells via the gp130 (Il6st) coreceptor bound either to the LIF receptor (LIFR) or the oncostatin M receptor (OSMR), but whether murine OSM can act through both receptors is controversial. Both LIF and OSM stimulate bone formation, inhibit adipocyte differentiation, and promote osteoclast differentiation, but our earlier work suggested this may depend on the receptor subtype used. This project aimed to identify those gene targets regulated by murine OSM via OSMR and LIFR by using wild type and OSMR null primary osteoblasts. Cells were differentiated to their most mature state (i.e. osteocytes) because the only prior target gene known to be regulated by murine OSM via the LIFR was an osteocyte-specific gene, sclerostin.

Project description:The human placenta is covered by a single multinucleated fetal cell, the syncytiotrophoblast, which is bathed in maternal blood. During all pregnancies, membrane enclosed extracellular vesicles derived from the syncytiotrophoblast are extruded into the maternal blood.The large size of these extracellular vesicles (diameter larger than 10µm) is referred to as trophoblastic debris in this study. We have shown in the past that endothleial cells are involved in clearence of this trophoblastic debris and induction of immune tolerence by trophoblastic debris.This study aimed to characterise the transcriptional changes that occur in human vascular endothelial cells following exposure to trophoblastic debris from normal first trimester placentae. Microarrays were used to probe transcriptomic changes 2 and 21 hours after exposure of endothelial cells (Human microvascular endothelial cell line,HMEC-1) to trophoblastic debris from normal first trimester placentae

Microarrays were used to probe transcriptomic changes 2 and 21 hours after exposure of endothelial cells (Human microvascular endothelial cell line,HMEC-1) to trophoblastic debris from normal first trimester placentae Trophoblastic debris were isolated by low speed centrifugation from three individual first trimester human placentae (three biological replicates). The protein content in trophoblastic debris was measured by BCA assay. HMEC-1 was co-cultured with trophoblastic debris (60ug/ml total debris protein contents) for either 2 or 21 hours before RNA extraction. Untreated HMEC-1 at 2 and 21 hours were used as controls.In total, 12 samples were analyzed.

Project description:Gene expressions obtained from the total RNA sequencing of 2 choriocarcinomas, 4 epithelioid trophoblastic tumors, and 4 placental site trophoblastic tumors were evaluated for differential gene expression, pathway alteration, fusion gene, infiltrating immune cell type, and PD-L1 expression level, and mutation analysis was performed using the RNA sequencing data.
