Project description:This study was designed to investigate gene expression in kidneys of adult female Sabra rats (SBH/y and SBN/y rat strains) with two indwelling kidneys or after uni-ninephrectomy, seeking those genes that are differentially expressed between the two strains, and between animals with one or two kidneys. SBH/y after uninephrectomy develop proteinuria to a much greater extent than SBN/y. The study was performed as part of an overall effort to detect the genes that are associated with the pathophysiology of proteinuria. Keywords: Analysis of genes that are differentially expressed in the kidneys, contrasting between an animal strain that tends to develop proteinuria which is amplified by uninephrectomy and another strain that is relatively resistant to the development of proteinuria

Keywords: Analysis of genes that are differentially expressed in the kidneys, contrasting between an animal strain that tends to develop proteinuria which is amplified by uninephrectomy and another strain that is relatively resistant to the development of proteinuria The experiment was performed in male animals after weaning. Four groups were studied: SBN/y with 2 kidneys (ham uni-nephrectomy), SBN/y after uni-nephrectomy, SBH/y with 2 kidneys (sham uninephrectomy) and SBH/y after uni-nephrectomy. Animals were provided rat chow ad libitum. At age 4 months, 3 months after uninephrectomy or sham operation, animals were sacrificed under ether anesthesia, killed by exsanguination and the kidneys were rapidly removed and snap frozen with liquid nitrogen. The kidneys were stored at -800C until RNA was extracted for the differentiale xpression experiment.

Project description:This study aims to investigate the DNA methylation patterns at transcription factor binding regions and their evolutionary conservation with respect to binding activity divergence. We combined newly generated bisulfite-sequencing experiments in livers of five mammals (human, macaque, mouse, rat and dog) and matched publicly available ChIP-sequencing data for five transcription factors (CEBPA, HNF4a, CTCF, ONECUT1 and FOXA1). To study the chromatin contexts of TF binding subjected to distinct evolutionary pressures, we integrated publicly available active promoter, active enhancer and primed enhancer calls determined by profiling genome wide patterns of H3K27ac, H3K4me3 and H3K4me1.
