Next Generation Sequencing and Analysis of the Transcriptomes of Wild-type and Alkbh5-/- Neutrophils

Project description:By performing transcriptome-wide RNA sequencing (RNA-seq) analysis on the peritoneal neutrophils from Alkbh5-deficient mice (Alkbh5-/-) and Wild-type littermates (Alkbh5+/+) at 12h or 36h after mild cecal ligation and puncture (CLP), respectively, we want to identify potential targets of ALKBH5 and characterize the transcriptional landscape in neutrophils during antibacterial innate defense. Gene Ontology biological processes enrichment analysis of the significantly differentially expressed genes (DEGs) showed that neutrophil migration made up the most significantly enriched biological processes with annotations of neutrophil association upon loss of ALKBH5 in neutrophils, at both 12h and 36h after CLP. Many significantly DEGs also encompassed transcriptional signatures related to neutrophils, specifically to neutrophil influx into the infection site, including chemotaxis, response to chemokine, extravasation, ERK1 and ERK2 cascade, homeostasis of neutrophils. ALKBH5 deletion led to significantly decreased transcript expression of neutrophil migration-promoting Cxcr2 and Nlrp12; while increased transcript expression of neutrophil migration-suppressive Ptger4, Tnc, and Wnk1. These results demonstrated that ALKBH5 imprints migration-promoting transcriptional landscape in neutrophils to enable their migration into the site of infection for antibacterial innate defense.

Next Generation Sequencing Analysis of the Transcriptomes of Wild Type and ALKBH5-/- Peritoneal Macrophages

Project description:By performing RNA sequencing (RNA-seq) analysis on the peritoneal macrophages that derived from ALKBH5-/- mice and littermate mice infected with or without vesicular stomatitis virus (VSV), we want to investigate whether deficiency of ALKBH5 controls viral replication through a more general mechanism such as enhancing innate response, and if not, what's the critical downstream target(s) of ALKBH5. RNA-seq analysis showed that mRNA expression of innate genes remained unchanged or not increased in ALKBH5-deficient cells. While thourgh KEGG pathway enrichment analysis of the RNA-seq data, we found that metabolic pathways were the ones most significantly affected in ALKBH5-deficient macrophages upon VSV infection. These results demonstrated that deficiency of ALKBH5 controls viral replication by significantly changing the metabolism-related genes expression.

Effect of depletion of ALKBH5 on transcriptional landscape in human neutrophils during bacterial infection

Project description:By performing RNA-seq analysis on ALKBH5-deficient (ALKBH5-/-, KO) and Wild-type (WT) dHL-60 human neutrophils infected with Escherichia coli, we want to investigate the effect of ALKBH5 on transcriptional landscape of human neutrophils during bacterial infection. Then, we performed gene expression profiling and Gene Ontology enrichment analysis of the significantly differentially expressed genes using data obtained from RNA-seq.

Effect of depletion of ALKBH5 on transcriptional landscape in bone marrow neutrophils from septic mice

Project description:By performing RNA-seq analysis on bone marrow neutrophils from the Alkbh5-deficient mice and Wild-type littermates undergoing CLP-induced sepsis, we want to investigate the effect of ALKBH5 on transcriptional landscape of mouse bone marrow neutrophils during bacterial infection. Then, we performed gene expression profiling and Gene Ontology enrichment analysis of the significantly differentially expressed genes using data obtained from RNA-seq.

Next Generation Sequencing Facilitates Quantitative Analysis of U87MG Cell Transcriptomes

Project description:Next-generation sequencing (NGS) has significantly advanced the elucidation of developmental signaling mechanisms that are important for U87MG cells under differente treatment. We report here the application of RNA-sequencing technology for transcriptome profile of U87MG cells treated with CAR neutrophils, nanodrugs, and CAR neutrophils loaded nanodrugs. Six U87MG samples were performed in IIIumina HiSeq2500. The resulting sequence reads were mapped to human genome (hg19) using HISAT, and the RefSeq transcript levels (RPKMs) were quantified using the python script rpkmforgenes.py. Our RNA-seq data analyzed different cellular signal pathways under treatment. This study shows a detailed analysis of U87MG transcriptomes generated by RNA-seq technology, providing insight into the mechanisms underlying CAR neutrophils lysis the tumor cells.

ALKBH5 is a New Mammalian RNA Demethylase

Project description:N6-methyladenosine (m6A) is the most prevalent internal modification of messenger RNA (mRNA) in higher eukaryotes. Here we report ALKBH5 as a new mammalian demethylase that oxidatively removes the m6A modification in mRNA in vitro and inside cells. This demethylation activity of ALKBH5 significantly affects mRNA export and RNA metabolism as well as the assembly of mRNA processing factors in nuclear speckles. Alkbh5-deficient male mice are characterized by impaired fertility resulting from apoptosis that affects meiotic metaphase-stage spermatocytes. In accordance with this defect, we have identified in mouse testes 1552 differentially expressed genes which cover broad functional categories and include spermatogenesis-related mRNAs involved in the p53 functional interaction network. We show that Alkbh5-deficiency impacts the expression levels of some of these mRNAs, supporting the observed phenotype. The discovery of this new RNA demethylase strongly suggests that the reversible m6A modification plays fundamental and broad functions in mammalian cells. RNA-seq in two cell types
