Project description:It has been well documented that pre-eclampsia and unexplained fetal growth restriction (FGR) has a common etiological background, but little is known about the linkage al the molecular level. we have performed global gene expression profiling by oligonucleotide microarrays for placentas from pre-eclamptic, unexplained FGR and normal pregnancies to further elucidate the mechanisms underlying the development of these two disorders. The total number of samples used was 8 from pre-eclampsia, 8 from normotensive pregnancies with FGR and 8 from those without FGR.
Project description:Genome-wide analysis of decidual transcriptome in pre-eclampsia compared with normotensive controls to find differentially expressed genes/pathways. Preeclampsia (PE) is a common and serious pregnancy hypertensive disorder with a strong genetic component. The study aims were to use genome-wide analysis of decidual transcriptome in pre-eclampsia compared with normotensive controls to identify differentially expressed biological pathways, and to determine common pathways between the transcriptome and previously identified maternal susceptibility genes. Total RNA from decidua basalis obtained from pre-eclamptic and normotensive control patients at Caesarean section

Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.
Project description:Transcriptional profiling of human mesenchymal stem cells comparing normoxic MSCs cells with hypoxic MSCs cells. Hypoxia may inhibit senescence of MSCs during expansion. Goal was to determine the effects of hypoxia on global MSCs gene expression.
Project description:Preeclampsia (PE) has been associated with placental dysfunction, resulting in foetal hypoxia, accelerated erythropoiesis and increased erythroblast count in the umbilical cord blood (UCB). Although the detailed effects remain unknown, placental dysfunction can also cause inflammation, nutritional and oxidative stress in the fetus that can affect erythropoiesis. Here, we compared the expression of surface adhesion molecules and erythroid differentiation capacity of UCB hematopoietic stem/ progenitor cells (HSPCs), UCB erythroid profiles along with transcriptome and proteome of these cells between male and female foetuses from PE and normotensive pregnancies. While no significant differences were observed in UCB HSPC migration/ homing and in vitro erythroid colony differentiation, the UCB HSPC transcriptome and the proteomic profile of the in vitro differentiated erythroid cells differed between PE vs normotensive samples. Accordingly, despite absence of significant differences in the UCB erythroid populations in male or female foetuses from PE or normotensive pregnancies, transcriptional changes were observed during erythropoiesis, particularly affecting male foetuses. Pathway analysis suggested deregulation in mTORC1/AMPK signaling pathways controlling cell cycle, differentiation and protein synthesis. These results associate PE with transcriptional and proteomic changes in foetal HSPCs and erythroid cells that may underlie the higher erythroblast count in the UCB in PE.
Project description:Gene methylation profiling of immortalized human mesenchymal stem cells comparing HPV E6/E7-transfected MSCs cells with human telomerase reverse transcriptase (hTERT)- and HPV E6/E7-transfected MSCs. hTERT may increase gene methylation in MSCs. Goal was to determine the effects of different transfected genes on global gene methylation in MSCs.
