Chrom-seq Identifies RNAs at Chromatin Marks [Chrom-seq]

ABSTRACT: Chromatin marks are associated with transcriptional regulatory activities. Here, We developed a method termed Chrom-seq to efficiently capture RNAs associated with various chromatin marks in living cells. Chrom-seq jointly applies highly specific chromatin-mark reader with APEX2 which catalyzes the oxidation of biotin-aniline to label the adjacent RNAs for isolation by streptavidin-coated beads. Using the readers of mCBX7/dPC, mCBX1 and mTAF3, we detected RNA species significantly associated with H3K27me3, H3K9me3 and H3K4me3, respectively. Chrom-seq provides an antibody-free approach to systematically map RNAs at chromatin marks with potential regulatory roles in different epigenetic events.

Chrom-Lasso：A lasso regression-based model to detect functional chromatin interactions using Hi-C data

Project description:We present Chrom-Lasso, an algorithm to identify chromatin interactions from Hi-C data, which performs better in identifying functional chromatin interactions that regulates gene expression when comparing with other methods. To futher assess its performance in investigating biological questions and its ability to deal with noisy data, we use an in vitro mouse CD8+ T cell activation model to generate Hi-C data and RNA-seq data at 4 status(Tn, Teff1, Teff2, Tex) during the process of activation, and we sort T cells at different status by gating criteria as follows: Tn(CD8+, CD44-, CD62L+, at day0), Teff1(CD8+, PD-1+, TIM-3-, at day2), Teff2(CD8+, PD-1+, TIM-3-, at day5), and Tex(CD8+, PD-1+, TIM-3+, at day5), for each status, we prepare 1 Hi-C library following the in situ Hi-C prorocol, and we also prepare 3 RNA-seq libraries from 3 times of parallel experiments. Since functional interactions influence the downstream gene expression level, so the relevance between interactions detected by Chrom-Lasso and gene expression would be powerful evidence proving the capability of Chrom-Lasso in detecting functional interactions.

USP11 deubiquitinates monoubiquitinated SPRTN to repair DNA-protein crosslinks

Project description:DNA-protein crosslinks (DPCs) are toxic DNA lesions that interfere with DNA metabolic processes such as replication, transcription, and recombination. SPRTN is a replication-coupled DNA-dependent metalloprotease that degrades proteins crosslinked to DNA to promote DPC repair. SPRTN function is tightly regulated by a monoubiquitin switch that controls SPRTN chromatin accessibility during DPC repair. The deubiquitinase regulating SPRTN function in DPC repair is unknown. To identify SPRTN modifiers, we performed tandem-affinity purification and mass spectrometry (TAP-MS) analysis of SFB (S-FLAG-streptavidin binding peptide)-tagged SPRTN expressed in HEK 293T cells. We screened the MS list for proteins that are known to function as a deubiquitinase and identified only one potential SPRTN modifier, USP11 deubiquitinase. A reciprocal TAP-MS analysis of SFB-USP11 expressed in HEK 293T cells treated with camptothecin (CPT) immunoprecipitated SPRTN. USP11 interacts with SPRTN and cleaves monoubiquitinated SPRTN in cells and in vitro. USP11 depletion impaired SPRTN deubiquitination in response to formaldehyde-induced DPCs. Loss of USP11 causes an accumulation of unrepaired DPCs and cellular hypersensitivity to treatment with DPC-inducing agents. Our findings elucidates the function of USP11 in the regulation of SPRTN monoubiquitination and SPRTN-mediated DPC repair.

Complete Genome Sequencing and Transcriptome Analysis of aniline-degrading strain T1

Project description:The aniline-degrading strain T1 can efficiently degrade aniline, however, it is not clear which key genes are associated with aniline degradation, and we have adopted a genome-wide and transcriptomic approach to fully understand the microbial degradation mechanism of aniline.
