Project description:The objective of the study was to comprehensively compare the genomic profiles in the breast of parous and nulliparous postmenopausal women to identify genes that permanently change their expression following pregnancy. The study was designed as a two-phase approach. In the discovery phase, we compared breast genomic profiles of 37 parous with 18 nulliparous postmenopausal women. In the validation phase, confirmation of the genomic patterns observed in the discovery phase was sought in an independent set of 30 parous and 22 nulliparous postmenopausal women.

Project description:The aim of the experiment was to identify the change of gene expression in human ovaries between premenopausal women and postmenopausal women based on DNA microarrays analysis. 8 human ovary samples were assembled from premenopausal women (n=4) and from postmenopausal women (n=4), respectively. The active transcription profiles of human ovaries were identified through DNA microarrays. Differentially expressed genes (DEGs) were identified as at least two-fold change with statistical significance. Enrichment of functions and signaling pathways analysis were performed based on Gene Ontology and the Kyoto Encyclopedia of Genes and Genomes database.

Project description:Mitochondrial and oxidative stress have been related to obesity and breast cancer, and this cancer is more frequent and more aggressive in postmenopausal women with obesity. To investigate if Mexican-Mestizo postmenopausal women with breast cancer and obesity presented different somatic mutations in the mitochondrial DNA (mtDNA) when compared to women with normal body mass index.

Project description:Using a large representative sample of postmenopausal women in the Norwegian Women and Cancer (NOWAC) postgenome study, we investigated blood gene expression changes due to intra-technical variability, normal inter-individuality (age, body mass index, fasting status), and exposure variables (smoking, hormone therapy and medication use) at proportion and level of real life situation revealing mechanistic insights of these effects mirrored in blood.

Project description:Adipocytes isolated from lean and obese postmenopausal women with no significant differences in metabolic syndrome parameters demonstrate changes in multiple inflammatory, metabolic and structural gene families. Purified adipocyte samples were isolated from subcutaneous adipose tissue surgical biopsies of 7 obese (BMI>30) and 7 lean (BMI<25) postmenoposal women and gene expression was quantified with Agilent-014850, 4X44K human whole genome platform arrays (GPL6480)

Project description:The onset of menopause is accompanied by a dramatic increase in reported symptoms of vaginal dryness, soreness, irritation or itching, pain with intercourse and bleeding after intercourse. Collectively these affect 25-50% of women of post-menopausal age and significantly impact their quality of life. To examine how gene expression differs between these groups, surface vaginal epithelial cells were collected from postmenopausal women suffering from vaginal dryness and appropriate controls not suffering from dryness. Affymetrix GeneChip Human 1.0 ST microarrays were performed on RNA isolated from ten participants.

Project description:Using a large representative sample of postmenopausal women in the Norwegian Women and Cancer (NOWAC) postgenome study, we investigated blood gene expression changes due to intra-technical variability, normal inter-individuality (age, body mass index, fasting status), and exposure variables (smoking, hormone therapy and medication use) at proportion and level of real life situation revealing mechanistic insights of these effects mirrored in blood. We used a representative sample of postmenopausal women (N=286) in the NOWAC postgenome study. We investigated blood gene expression changes due to intra-technical variability, normal inter-individuality (age, body mass index, fasting status), and exposure variables (smoking, hormone therapy and medication use). A total of 304 arrays, including 18 technical replicates, were analyzed. We filtered out samples which had less than 40% probes with a signal to noise ratio (S/N) greater than or equal to 3. When a technical replicate was conducted, the array with the least number of probes with S/N greater than or equal to 3 was excluded. After samples filtration, a total of 286 arrays were analyzed. The following samples were filtered out; they were not used in the normalization processing, and none of the study conclusions are based on these samples.

However, the metadata for the filtered-out samples is included in the Series supplementary file GSE15289_filtered_metadata.txt. The raw data for both the filtered-out samples and non-filtered-out samples (GSM381832-GSM382117) are included in the Series supplementary file GSE15289_raw.txt.

Project description:Postmenopausal osteoporosis (PMOP) is a major global public health concern and older women are more susceptible to experiencing fragility fractures. Our study investigated the associations between circulating proteins with bone mineral density (BMD) in postmenopausal women with or without low BMD (osteoporosis and osteopenia) to explore the pathogenesis of PMOP and discover novel biomarkers for this disease..
