Next Generation Sequencing Analysis of Wild Type Mouse Embryonic Fibroblast (MEFs) Transcriptomes Stimulated by Viral Mimics

Project description:Purpose: The goals of this study are to use NGS to perform transcriptome profiling (RNA-seq) to find the changes of the global gene expression programs after viral mimic stimulation in Mouse Embryonic Fibroblasts (MEFs) Methods: MEFs were staimulated by 10 ug/ml Poly(dA:dT) or Poly(I:C) using Lipofectamine 2000 (Invitrogen) as transfection regaent in Opti-MEM medium for 6 hours. Mock groups were treated only with transfection regaent. Total RNA was extracted using RNeasy Mini Kit (Qiagen) according to the manufacturer protocol. Total RNA was used for library construction at the Center for Genomics and Systems Biology, New York University Abu Dhabi, using TruSeq RNA Library Prep Kit v2 (Illumina). Deep-sequencing was performed using Illumina HiSEq 2500 sequencing platform (New York University Abu Dhabi Sequencing Center). Data was processed through the standard RNAseq analysis pipeline at NYUAD. Read aligmnet was performed using tophat2 v2.1.0 against Mus musculus GRCm38.p4 genome version. Raw counts of mapped reads of each genes were derived using HTseq count. DESeq2 was used for differential expression analysis. Results: Using an optimized data analysis workflow, we identified genes up-regulated or down-regulated after anti-viral immunity activation. Gene ontology analysis further identified biological processes, cellular components and molecular functions that were overrepresented in the differentially expressed genes. Conclusions: Our study provides a good reourses for profiling genes regulations after viral immunity activation

ATAC-Seq analysis of Mouse Embryonic Fibroblasts (MEFs) to understand the role of β-actin in regulating chromatin states

Project description:β-actin is a crucial component of several chromatin remodeling complexes which control chromatin structure and accessibility. The mammalian Brahma-associated factor (BAF) is one such complex that plays essential roles in development and differentiation by regulating the chromatin state of critical genes and opposing the repressive activity of polycomb repressive complexes. While previous work has shown that β-actin loss can lead to extensive changes in gene expression and heterochromatin organization, it is not known if changes in β-actin levels can directly influence chromatin remodeling activities of BAF and polycomb proteins. Here we conduct a comprehensive genomic analysis of β-actin knockout mouse embryonic fibroblasts (MEFs) using ATAC-Seq, HiC-seq, RNA-Seq and ChIP-Seq of various epigenetic marks. We demonstrate that β-actin levels can affect the complex interplay between chromatin remodelers such as BAF/BRG1 and EZH2 in a dosage-dependent manner. Our results show that changes in β-actin levels and associated chromatin remodeling activities can not only impact local chromatin accessibility but also induce reversable changes in 3D genome architecture. Our findings support a novel role for β-actin levels in shaping the chromatin landscape during development and differentiation.

β-actin RNA-BioID

Project description:Function and fate of mRNAs is controlled by RNA binding proteins (RBPs) but determining the proteome of a specific mRNA in vivo is still challenging. RNA proximity biotinylation on the transported β-actin mRNA tagged with MS2 aptamers (RNA-BioID) is used to characterize the dynamic proteome of the β-actin mRNP in mouse embryonic fibroblasts (MEFs). We have identified > 60 β-actin associated RBPs including all six previously known as well as novel interactors. By investigating the dynamics of the β-actin mRNP in MEFs, we expand the set of β-actin mRNA associated RBPs and characterize the changes of the interacting proteome upon serum-induced mRNA localization. We report that the KH-domain containing protein FUBP3 represents a new β-actin associated RBP that binds to its 3’-untranslated region outside the known RNA localization element but is required for β-actin RNA localization. RNA-BioID will allow to obtain a dynamic view on the composition of endogenous mRNPs.
