Project description:We over-expressed an epigenetic regulator in a glioblastoma (GBM) primary culture from an adult patient. These GBM cells have cancer stem cell phenotypes, as they have self-renewal properties and tumor initiation potential when transplanted in immunocompromised mice. ATAC-seq was performed on cells over-expressing the epigenetic regulator and control cells expressing EGFP. ATAC-Seq on glioblastoma cells that over-express EGFP or an epigenetic regulator.
Project description:We performed ATAC-seq assay on nuclei isolated from control and UTXKO mouse brown fat to delineate the role of UTX in setting chromatin accessibility. We analyzed the effects of UTX deficiency on a set of brown fat specific genes and observed reduced accessibility at ATAC-seq peaks and mRNA expression for many of these genes, including PRDM16 and PGC1a.
Project description:Brown adipocytes (BAs) are a potential therapeutic cell source for the treatment of metabolic disease such as type 2 diabetes. In this report, human pluripotent stem cells (hPSCs) are subject to directed differentiation to brown dipocytes through a paraxial mesoderm intermediate at high-efficiency. RNA-Seq and ATAC-seq was performed to characterized hPSCs derived paraxial mesoderm and brown adipocytes generated in this study.

Project description:Brown bear modern and palaeogenome study
Project description:ATAC-seq samples from 2 species and 2 cell types were generated to study cis-regulatory element evolution. Briefly, previously generated urinary stem cell derived iPS-cells (Homo sapiens) of 2 human individuals and fibroblast derived cynomolgus macaque iPSCs (Macaca fascicularis) of 2 individuals (Geuder et al. 2021) were differentiated to neural progenitor cells via dual-SMAD inhibition as three-dimensional aggregation culture (Chambers et al. 2009; Ohnuki et al. 2014). The NPC lines were cultured in NPC proliferation medium and passaged 2 - 4 times until they were dissociated and subjected to ATAC-seq together with the respective iPSC clones. ATAC-seq libraries were generated using the Omni-ATAC protocol (Corces et al. 2017) with minor modifications.
Project description:To elucidate the sex-specific role of PGC1α in brown adipose tissue (BAT), we performed ATAC-seq analysis on BAT from male and female PGC1α knockout mice.
Project description:Male and female 2- and 3-years old brown bear from the region of Tackasen (Sweden) were captured in summer and winter. Muscle biopsies from vastus lateralis were collected in february (hibernation state) and june (active period). Total RNA were extracted from muscle tissue and full transcriptome analysis (RNA Seq) were performed. Statistical analysis were performed to winter versus summer comparison from matched paired samples
