Project description:The activation of hypoxia-inducible transcription factors (HIF) leading to the expression of hundreds of target genes is a fundamental mechanism in acute and chronic kidney disease, mediating protective but possibly harmful effects. Furthermore, dysregulation of the HIF pathway in chronic kidney disease causes renal anemia through insufficient erythropoietin (EPO) induction in interstitial cells. RNA-seq analysis was performed in human primary renal tubular cells to analyse the effect of HIF stabilization on the expression of genes in tubular cells. ATAC-seq and HIF-CHIP-seq complement the data to analyse transcription factor binding and chromatin configuration changes.

Project description:Activation of hypoxia-inducible transcription factors (HIF) leading to expression of hundred of target genes is a fundamental mechanism in acute and chronic kidney disease mediating protective but also possibly harmful effects. Furthermore, dysregulation of the HIF pathway in chronic kidney disease causes renal anemia through insufficient induction of erythropoietin (EPO) in interstitial cells. Hence, pharmacological compounds to treat renal anemia by stabilizing HIF have recently been introduced to the clinical practice. RNA-seq analysis was performed in primary renal tubular cells to analyse the effect of HIF stabilization on the expression of pathogenic Mucin1 (MUC1) variants. This study links the regulation of the kidney-disease gene MUC1 with the HIF-pathway in renal tubular cells.
