Project description:The RNA methyltransferase Aly/REF export factor (ALYREF) is considered one type of “reader” protein located in the nucleus that recognizes and binds directly with m5C sites in RNA and facilitates the export of RNA from the nucleus to the cytoplasm. Notably, ALYREF is considered a promising target for diagnosis and prognosis prediction. However, until now, the low number of related studies has limited the understanding of the mechanism of the HCC-promoting effects of ALYREF. To further elucidate the oncogenic roles of ALYREF in hepatocellular carcinoma (HCC), we assessed the expression levels of ALYREF in clinical samples and HCC cell lines and explored the effects of ALYREF deficiency by both in vitro experiments and m5C-methylated RNA immunoprecipitation sequencing (m5C-MeRIP-Seq)

Project description:We have identified Alyref and Gabpb1 as developmentally important genes by siRNA screening. Gene knockout (KO) of Alyref and Gabpb1 by the CRISPR/Cas9 system resulted in early developmental arrest in mice. To gain mechanistic insight into the developmental role of Alyref and Gabpb1, we performed RNA sequencing (RNA-seq) analysis of the KO embryos.

Project description:To examine whether the competition between hMTR4 with ALYREF is important for the specific exosome recruitment, we performed stranded RNA-seq using rRNA-depleted nuclear RNAs isolated from ALYREF and control overexpression cells.

Project description:we try to investigate the binding of ALYREF and NXF1 on histone mRNA when the cell treated with indicated siRNAs. ALYREF plays key roles in nuclear export of polyadenylated mRNAs and also modulates their 3' processing, but whether it is involved in regulating RNAs beyond polyadenylated mRNAs is unknown. The replication-dependent (RD) histone mRNAs are not polyadenylated, but end in a stem-loop (SL) structure. Here we demonstrate that ALYREF prevalently binds a region next to the SL on RD histone mRNAs. SL-binding protein (SLBP) directly interacts with ALYREF and ensures this binding. To examine how SLBP KD impact ALYREF distribution on the histone mRNA, we carried out ALYREF iCLIP in control and SLBP KD cells. To investigate the functional consequence for ALYREF binding on histone mRNAs, we isolated polyA+ and polyA- RNAs from control and ALYREF KD cells, and carried out RNA-seq separately.

Project description:Through deep RNA-seq of human monocyte-derived macrophages, we identified RP11-184M15.1, a human macrophage-specific lincRNA, to be highly induced in the cytoplasm of IL-4-stimulated macrophage. Preliminary data showed that treatment of IL-4-stimulated THP1 human macrophages with RP11-184M15.1 small interfering RNA (siRNA) repressed apoptosis of resolving macrophages, as shown by decreased Annexin V+ macrophages, and reduced protein expression of cleaved PARP. Biotinylated RP11-184M15.1 pulldown coupled with mass spectrometry indicated an interaction between RP11-184M15.1 and zinc finger RNA-binding protein (ZFR). RIP corroborated the proposed interaction between RP11-184M15.1 and ZFR. RNAInter revealed mRNAs predicted to interact with ZFR, and some of those genes (e.g., ALYREF, CCNYL1) were also differentially expressed in RNA-seq data of control versus RP11-184M15.1 knockdown in IL-4-stimulated THP1 macrophages. qPCR validated that ALYREF and CCNYL1 expression are reduced with RP11-184M15.1 knockdown. In contrast, with ZFR siRNA, ALYREF and CCNYL1 mRNA expressions were elevated. Thus, a hypothesis to be further tested is that RP11-184M15.1 interacts with ZFR to regulate mRNA stability in IL-4-stimulated macrophages. Nuclear RNA export factor 1 (NXF1) was also validated by RIP to interact with RP11-184M15.1. NXF1 is a known interacting partner of ALYREF in the transcription-export (TREX) complex. With RP11-184M15.1 knockdown, the protein level of ALYREF decreased, and Ingenuity Pathway Analysis (IPA) of RNA-seq data of control versus RP11-184M15.1 knockdown revealed that THO complex subunit 5 homolog (THOC5), another component of the TREX complex, may be an upstream regulator. In addition, past studies have revealed that ALYREF and NXF1 are involved in nuclear export of inflammatory mRNAs and proinflammatory macrophage phenotype, respectively. With RP11-184M15.1 knockdown, there was decreased expression of inflammatory macrophage-associated genes. It may be possible that RP11-184M15.1 functions in mRNA export, along with NXF1 and ALYREF.
