Project description:SOX6 CUT&RUN on HUDEP1 over expressing SOX6-Flag. The experiment is done using and anti Flag Ab to assist the genome wide binding profile of SOX6 in HUDEP1 (Human Umbilical cord blood-Derived Erythroid Progenitor-1).
Project description:Purpose: Identification of glucocorticoid recepor binding sites on human kidney proximal tubular cells to better understand epigenetic alterations in diabetic kidney diseases Methods: CUT&RUN assay libraries for cultured cells or human kidneys were generated with the CUTANA kit (EpiCypher, 14-1048). 500,000 cells were mixed and incubated with Concanavalin A (ConA) conjugated paramagnetic beads. Antibodies to the glucocorticoid receptor were added to target samples and IgG was added to negative controls. The remaining steps were performed according to manufacturer’s instructions. Library preparation was performed using the NEBNext Ultra II DNA Library Prep Kit for Illumina (New England BioLabs, E7645S) with manufacturer’s instructions, including minor modifications indicated by CUTANA described above. CUT&RUN libraries were sequenced on a NovaSeq instrument (Illumina, 150 bp paired-end reads). For bulk ATAC-seq, 50,000 nuclei were transposed in 25 μL of ATAC-seq transposition mix [12.5 μL 2× Illumina Tagment DNA (TD) buffer; 10.5 μL nuclease-free water; 2.0 μL Tn5 transposase (Illumina/Nextera, FC-121-1030)] and incubated at 37°C for 1 h on a thermomixer. The transposed DNA was purified with QIAGEN MinElute kit (28004) and amplified with dual indexes.
Project description:Activation of A Disintegrin and A Metalloprotease Domain17 (ADAM17) is involved in nephropathy, but the role of this metalloprotease and its inhibitor TIMP3 in diabetic kidney disease is unclear. We used microarray profiling to find genes differentially expressed in the 2 genotypes which could explain the more severe diabetic kidney disease features observed in T3-/- mice compared to the WT littermates. Total RNA was extracted from 3 WT and 3 Timp3-/- diabetic kidneys
