Project description:The affection of Sirt1 on astrocyte is not well understanded. Here we studied the change of RNA expression profile after Sirt1 knockout in primary astrocyte after stimulating with A1 astrocyte inducing cocktails. To analyze the change of RNA expression profile after Sirt1 knockout in astrocytes, we built Sirt1 knockout and control astrocytes using crispr technique, and analyzed RNA expression profiles of Sirt1 KO and control astrocytes after treating with cocktail (C1q, IL-1α, TNF-α) by using microarray.
Project description:RNA-seq analysis (proinflammatory cocktail vs. control) of total RNA isolated from patient-derived colon organoids established from an ulcerative colitis patient. The analysis aimed at characterizing the epithelial gene expression changes post proinflammatory stimulation. ***Please note that raw data is not provided as Norwegian law does not allow public access to human sequences raw data
Project description:Direct current electric field mimicking a physiological electrical field from transepithelial potential difference can direct cell migration (electrotaxis)and cellular signaling. While the transcriptome in dcEF has been reported and more studied, the miRNA expression of cells under dcEF stimulation is less understood. We use a reversibly sealed dcEF stimulation bioreactor to apply uniform dcEF to glioblastoma cell lines and primary astrocytes and investigate if dcEF can induce differential expression of cellular miRNA and exosomal miRNA expression that can regulate the gene expression
Project description:In order to understand the mechanism associated with SIRT1-mediated development of prostate cancer progression, we conducted RNA-sequencing analysis in SIRT1 suppressed hormone sensitive prostate cancer cells (LNCaP) under conditions of androgen sufficiency, deprivation, androgen stimulation or AR suppression.
Project description:C57BL6 mice harboring Sirt1 conditional knockout NOTCH1-DE-induced leukemias were treated with vehicle (control) or tamoxifen to induce isogenic deletion of Sirt1. Here we report the gene expression profile of leukemic blasts obtained from the spleen from control- or tamoxifen-treated leukemic mice.
Project description:To explore the pathology of liver-specific Sirt1 knockout mice. To specify, the liver-specific Sirt1 knockout mice commenced high blood glucose within three months. When the mice age extended to one year, the mice present surprising higher lung tumor vulnerabilities in contrast to wild type, we explore the underlying mechanism of the symptom
