Project description:To elucidate the biological role of ATF4 in regulating downstream target genes, we conducted a CUT&Tag assay in primarily cultured neurons.
Project description:To determine the biological function of ATF4 in the modulation of downstream target genes, we performed Tagmentation (CUT&Tag) assay in HCT 116 (Human colorectal cancer) cells
Project description:To reveal the role of NCOA7 in cellular senescence, we performed the CUT&TAG assay using the H3K27ac antibody to map acetylation in granulosa cells from control and POI patients. We conducted the DNA sequencing of libraries from CUT&TAG assay using the H3K27ac antibody in human primary granulosa cells.
Project description:To reveal the role of MCM8 in suppressing R-loop accumulation, we performed the CUT&TAG assay using the S9.6 antibody to map genome-wide R-loops in Mcm8 wildtype MEFs and Mcm8 knockout MEFs. We also conducted the CUT&TAG assay to detect genome-wide R-loops in Ddx5 downregulated MEFs by adenovirus infection and in control MEFs. To investigate the underlying molecular mechanism of MCM8 suppressing R-loops, we conducted the DNA sequencing of libraries from CUT&TAG assay using the antibody against FLAG in HEK293 cells transfected with FLAG-MCM8 plasmid and using the S9.6 antibody in HEK293 cells. Besides, an IgG control and control of RNH1 overexpression were included.
Project description:Activating Transcription Factor 4 (ATF4) is a transcription factor that regulates cellular responses to nutrient deficiency, endoplasmic reticulum stress and oxidative stress. At the organism level, it is implicated in processes such as hematopoiesis, skeletogenesis, eye development, memory, muscle atrophy, and carbohydrate and lipid metabolism. Here, we carried out a massively parallel reporter assay (MPRA) to identify allelic regulatory effects of human genetic variants that reside in ATF4 binding sites identified in ChIP-Seq experiments.
Project description:We performed the cleavage under targets and tagmentation (Cut & tag) assay followed by sequencing enriched DNA fragments to reveal the direct downstream targets of Pbx1. Firstly, we overexpressed Pbx1b with Pbx1b-IRES-GFP retrovirus in murine peripheral B cells to ensure the yields of DNA fragments. CUT & tag libraries were generated following instructions of the manufacturer’s protocol (Vazyme; cat TD901-01) and the Pbx1 antibody (CST; cat 4342) was used for signal enrichment.
Project description:In this study, CUT&Tag-seq technology was employed to investigate MEF2A binding sites across the entire genome of chicken primary myoblasts. CUT&Tag was performed using CUT&Tag Assay Kit for Illumina Pro (TD904-1) from Vazyme. Antibody targeting MEF2A as well as IgG were used.The final DNA library on a HiSeq PE150 platform was subjected for the analyses. This study provides a wide landscape of MEF2A target genes from chicken primary myoblasts, which supports the active role of MEF2A in avian muscle development.
