Comprehensive role of Zfp217 in m6A methylation [RIP-seq]

ABSTRACT: Many transcriptional and epigenetic networks must be integrated to maintain self-renewal and pluripotency in embryonic stem cells (ESCs) and to enable induced pluripotent stem cell (iPSC) reprogramming. Here, we explore the role of Zfp217and Mettl3 as RNA-binding proteins. Identification and characterization of RNAs associated with Zfp217 and Mettl3 in mouse embryoinc stem cells

Reduced expression of RBM47 enhances Nrf2 activity to promote tumor growth in A549 lung adenocarcinoma cells

Project description:We identified RNA binding motif protein 47 (RBM47) as a target gene of transforming growth factor (TGF)-beta in mammary gland epithelial cells (NMuMG cells) that have undergone the epithelial-to-mesenchymal transition (EMT). TGF-beta repressed RBM47 expression in NMuMG cells and lung cancer cell lines. Expression of RBM47 correlated with good prognosis in patients with lung, breast, and gastric cancer. RBM47 suppressed the expression of cell metabolism-related genes, which were the direct targets of nuclear factor erythroid 2-related factor 2 (Nrf2; also known as NFE2L2). RBM47 bound to KEAP1 and Cullin3 mRNAs, and knockdown of RBM47 inhibited their protein expression, which led to enhanced binding of Nrf2 to target genomic regions. Knockdown of RBM47 also enhanced the expression of some Nrf2 activators, p21/CDKN1A and MafK induced by TGF-beta. Both mitochondrial respiration rates and the side population cells in lung cancer cells increased in the absence of RBM47. Our findings, together with the enhanced tumor formation and metastasis of xenografted mice by knockdown of the RBM47 expression, suggested tumor suppressive roles for RBM47 through the inhibition of Nrf2 activity. Effect of shRNA for RBM47 and TGF-beta on gene expression was evaluated by RNA-seq and RBM47-bound RNAs were identified by RIP-seq in A549 cells.

RNA methylation destabilizes developmental regulators in murine embryonic stem cells (MoGene-2)

Project description:Recent methylome studies have located N6-methyladenosine (m6A) RNA modification on thousands of mammalian transcripts. However, its functional mechanism remains unclear. In this study, we examined the role of m6A methylation in mouse embryonic stem cells. To gain an understanding of dynamic changes in cells depleted with (proposed) methyltranferases at molecular level, we examined the time-series gene expression pattern in mESC lines using microarray analysis. After 0, 4 and 8 h incubation with scramble, shRNA for Mettl3 or Mettl14, mESC cells were collected and RNAs were isolated for microarray analysis using Affymetrix Genechip Mouse Gene 2.0 ST array. After 0 h incubation with scramble, shRNA for Mettl3 or Mettl14, mESC cells were collected and RNAs were isolated for microarray analysis using Affymetrix Genechip Mouse Gene 2.0 ST array.
