Transcript profiling of oestrogen treatment of primary human neuronal and glial cell cultures

ABSTRACT: The purpose of this experiment was to identify oestrogen regulated genes in human primary cell cultures of neuronal and glial cells modelling the developing human nervous system. We were especially interested in genes involved in proliferation, differentiation and migration of neuronal cells and genes involved in or linked to neurodegenerative diseases. We have therefore assessed gene expression changes, using Affymetrix GeneChips (HG-U133A), of oestrogen treated human neuronal/ glial cell cultures. We continued with 14 selected genes and confirmed the gene expression changes, by relative quantitative real time PCR, of 6 genes (p< 0.05) important in neuronal development, three of which also are suggested to have links to neurodegenerative diseases.

Transcription profiling of human rimary human neuronal and glial cell cultures response to estrogen treatment

Project description:The purpose of this experiment was to identify oestrogen regulated genes in human primary cell cultures of neuronal and glial cells modelling the developing human nervous system. We were especially interested in genes involved in proliferation, differentiation and migration of neuronal cells and genes involved in or linked to neurodegenerative diseases.

We continued with 14 selected genes and confirmed the gene expression changes, by relative quantitative real time PCR, of 6 genes (p< 0.05) important in neuronal development, three of which also are suggested to have links to neurodegenerative diseases. Experiment Overall Design: Primary mixed neuronal/glial cell cultures were established from human brain tissue, which was obtained from 8-12 weeks old fetuses at legal abortion after informed consent from the patients. Procedures were approved by the local Ethics committee at the Karolinska University Hospital, Stockholm. A total of 23 tissue samples yielding 9 cell cultures were used in this experiment. Half of the cell cultures were treated with 2ÂµM Î²-oestradiol the day after seeding. The duration of the oestrogen treatment was 7 days and the cells were harvested after 8 days of culturing for RNA extraction. Extracted RNA from untreated respectively oestrogen treated cell cultures were pooled yileding two samples, which were each hybridised to Affymetrix microarrys. In this study oestrogen treatment of human neuronal/glial cell cultures was found to regulate 6 genes important in the development of the nervous system.

Procedures were approved by the local Ethics committee at the Karolinska University Hospital, Stockholm. A total of 28 tissue samples yielding 10 cell cultures were used in this experiment. Half of the cell cultures were treated with 2ÂµM Î²-oestradiol the day after seeding. The duration of the oestrogen treatment was 7 days and the cells were harvested after 8 days of culturing for RNA extraction.

Direct Conversion of Human Fibroblasts into Neuronal Restricted Progenitors

Project description:Neuronal restricted progenitors (NRPs) represent a type of transitional intermediate cells that lie between multipotent neural progenitors (NPs) and terminal differentiated neurons during neurogenesis. These NRPs have the ability to self-renew and differentiate into neurons, but not into glial cells, which is considered as an advantage for cellular therapy of human neurodegenerative diseases. However, difficulty in the extraction of highly purified NPRs from normal nervous tissue prevents further studies and applications. In this study, we reported conversion of human fetal dermal fibroblasts into human induced neuronal restricted progenitors (hiNRPs) in seven days by using just three defined factors: Sox2, c-Myc, and either Brn2 or Brn4. The hiNRPs exhibited distinct neuronal characteristics, including cell morphology, multiple neuronal markers expression, self-renewal capacity, and genome-wide transcriptional profile. Moreover, hiNRPs were able to differentiate into various terminal neurons with functional membrane properties, but not glial cells. Direct generation of hiNRPs from somatic cells will provide a new source of cells for cellular replacement therapy of human neurodegenerative diseases. This is a general expression microarray design (NimbleGen platform). It includes 5 samples.

Comparing oestrogen-responsive genes in endometrial and breast cancer cell lines

Project description:Up to 80% of endometrial and breast cancers express the oestrogen receptor ERa. Unlike breast cancer, anti-oestrogen therapy has had limited success in endometrial cancer, raising the possibility that oestrogen has different effects in the two cancer types. We investigated the role of oestrogen in endometrial and breast cancers using cell lines and found that oestrogen-responsive genes were predominantly unique between the two cancer types.

Oestrogen promotes innate immune invasion of Candida albicans through inactivation of complement

Project description:Candida albicans is a commensal of the urogenital tract and the predominant cause of vulvovaginal candidiasis (VVC). Roughly, 70% of otherwise healthy women succumb to VVC at least once in their life time. Elevated oestrogen levels are associated with C. albicans colonisation of the vagina and symptomatic infection. However, little is known about how C. albicans adapts to oestrogen. Here, we investigate how adaptation of C. albicans to elevated concentrations of oestrogen on the C. albicans host-pathogen interaction. Growth of C. albicans in physiological relevant concentrations of oestrogen promoted fungal innate immune evasion through reduction of both macrophage and neutrophil phagocytosis. Oestrogen-induced innate immune evasion was mediated via inhibition of opsonophagocytosis through enhanced Gpd2 dependent acquisition of Factor H on the fungal cell surface. The zebrafish larval model of infection confirmed that in vivo oestrogen and Gpd2 promote pathogenicity. Understanding the impact of oestrogen on C. albicans host-pathogen interaction will help improve our knowledge on how oestrogen promotes VVC.
