Project description:To explore the effect of LIN28 (S200) phosphorylation on LIN28's association with mRNAs on a transcriptome-wide scale, we performed mRNA-seq on RNAs immunoprecipitated (RIP-seq) by wild-type (WT) or phospho-mimetic (S200D) LIN28 in PA1 cells.
Project description:To explore the effect of LIN28 (S200) phosphorylation on LIN28's association with mRNAs on a transcriptome-wide scale, we performed mRNA-seq on RNAs immunoprecipitated (RIP-seq) by wild-type (WT) or phospho-null (S200A) LIN28 in HeLa cells.
Project description:Label-free proteome analysis of small extracellular vesicles (sEV) derived from WM9 cells expressing different HRS mutants: wild type (HRSWT), phospho-deficient (HRSS345A), and phospho-mimetic mutant HRS (HRSS345D).
Project description:Purpose: The goals of this study are to investigate the mRNAs that bind to the FTO protein in the white fat tissue from mice. Methods: 1. White fat from CAG promoter driven transgenic Flag-tagged FTO mice were extracted with RNA protected. 2. Flag-FTO proteins were immunoprecipitated with control IP using IgG. 3. The immunoprecipitated RNAs were deep sequenced and analyzed. Results: We focused on the mRNAs which have functions related to lipid metabolism and homeostasis.
Project description:We study the gene regulation function of serine 473 phosphorylation of KAP1 (pS473-KAP1) in MDA-MB-231 cells. Wild type KAP1, S473A-KAP1 (phospho-acceptor site mutant) and S473D-KAP1 (phospho-mimetic mutant) are re-expressed in KAP1 knockdown cells. We analyze the gene expression profile in these three cells and find that many mitochondrial complex genes are up-regulated in S473D-KAP1 re-expressing cells. This study provides information about pS473-KAP1-regulated gene expression.
Project description:Isolation of IMP1 bound mRNAs. Flag-tagged IMP1 was expressed in HEK293 cells. Flag tagged IMP1 was immunoprecipitated and mRNAs isolated. As controls HEK293 cells that do not express Flag-tagged IMP1 was included.

Immunoprecipitated RNAs profiles from Flag-FTO IP and IgG IP were generated by deep sequencing.
Project description:To reveal the influence of TND-interacting motifs (TIMs), which bind TFIIS N-terminal domains (TNDs), we prepared KELLY cells expressing either wild-type IWS1-FLAG or IWS1-FLAG containing disruptive mutations in the unstructured TIM3 region. Following lentiviral transduction of either WT or M3 IWS1-FLAG, we performed ChIP using anti-FLAG antibodies from these samples and performed chromatin occupancy profiling using ChIP-seq. Analysis of locations reveal that both WT and M3 samples are highly enriched in at transcribed gene bodies.
