Project description:CHOPS syndrome is caused by germline gain-of-function mutations of AFF4. Cornelia de Lange syndrome is caused by germline mutations of cohesin loading factors or cohesin complex genes such as NIPBL, SMC1A, SMC3 and HDAC8. There are many overlapping clinical features exist between CHOPS syndrome and Cornelia de Lange syndrome. To identified commonly dysregulated genes in CHOPS syndrome and Cornelia de Lange syndrome, we perfomred side-by-side transcriptome comparison between CHOPS syndrome and Cornelia de Lange syndrome. In this transcriptome analysis, patient derived skin fibroblasts from two CHOPS syndrome probands, two Cornelia de Lange syndrome probands, and four age-gender-ethnicity matched healthy control subjects were used.The samples used for Human Gene 2.0 arrays are two CHOPs syndrome samples (CDL160 and CDL444), two Cornelia de Lange syndrome samples (CdL006: 7 year-old Caucasian female NIPBL 742_743delCT ;L248TfsX6 and CdL015: 10 year-old Caucasian male NIPBL 2969delG;G990DfsX2), and four age gender matched control samples (GM01652, GM01864, GM02036 and GM03348).

Project description:Comparison between miRNA expression in plasma of women with and without metabolic syndrome. We used microarrays to compare the composition of miRNAs in plasma of participants with and without metabolic syndrome (ATP III criteria).
Project description:Turner syndrome is a relatively rare condition that is usually associated with the loss of all or part of an X chromosome. Amniotic fluid is a complicated biological material, could contribute to the understanding of turner syndrome pathogenesis. In this study, ATAC-seq analysis of Turner syndrome (45X) and Female (46XX) amniotic fluid cells was applied to illustrate that genome wide chromatin accessible landscapes. Our results show that Turner Syndrome has higher chromatin accessibility than Female on autosomes and has lower chromosome accessibility on the X chromosome. We identified candidate genomic regions and transcript factors that may play an important role in Turner syndrome pathogenesis. Our analysis suggests that the phenotype of Turner Syndrome should be the result of abnormal regulation of gene expression in the whole genome, not just the result of insufficient doses of X chromosome haploids.
Project description:Characterization of gene expression profile of normal human and Kindler Syndrome (KS) patients skin biopsies samples, to extend the knowledge of transcriptional changes in the Kindler syndrome disease. For this micro array three age-, site - and sex-matched biopsies form control and Kindler Syndrome patients were analyzed.
