mRNA profiles of WTAP siRNA-treated HUVECs

Project description:To examine the role of WTAP in splicing regulation, we performed high-throughput mRNA sequencing (RNA-seq) on RNA isolated from control, WTAP or Virilizer siRNA-treated HUVECs, yielding 12 million uniquely mapped 75nt pair-end tags from each sample. MapSplice software was used for differential expression and differences in transcript splice junctions . mRNA profiles of control, WTAP or Virilizer siRNA-treated HUVECs were generated by deep sequencing using Illumina GAII.

Identification of WTAP complex-regulated alternative splicing/polyadenylation

Project description:Through combined comprehensive analysis of AS events via RNAi, coupled with RNA-seq analysis, we demonstrate that the WTAP complex core factors WTAP, VIRMA, KIAA0853 and CBLL1 function as splicing regulators to promote exon skipping and intron retention, several of which occur in the last exon with competition between splicing and polyadenylation. The regulated alternative splicing (AS) events involve short introns/exons with higher GC content and introns with weaker polypyrimidine-tract and branch points. Further analysis of GC-rich sequences of WTAP-regulated AS events revealed potential G-quadruplex formation.

The effects of WTAP on BAT function

Project description:Purpose: The goal of this study is to compare transcriptome profilings of interscapular brown adipose tissue (iBAT) from BAT-specific WTAP knockout and control mice Methods: iBATs were collected from WTAP BKO and f/f mice at 8 weeks old (n=3 for each group), and total RNA was isolated using TriPure. RNA-seq was performed by using Illumina NovaSeq 6000 platform. Paired-end clean reads were aligned to the mouse reference genome (Ensemble_grcm38_p6) with TopHat (version 2.0.12), and the aligned reads were used to quantify mRNA expression by using HTSeq-count (version 0.6.1). Conclusion:Our study represents the first detailed analysis of iBAT transcriptomes from WTAP BKO and f/f mice, generated by RNA-seq technology. The RNA-seq analysis showed that 894 genes were down-regulated and 1410 genes were up-regulated in the iBAT of WTAP BKO mice. GO analysis showed that the down-regulated genes were primarily related to related to generation of precursor metabolites and energy, cellular respiration, energy derivation by oxidation of organic compounds, electron transport chain, nucleotide metabolic process and purine ribonucleotide metabolic process.

WTAP is a novel oncogenic protein in Acute Myeloid Leukemia

Project description:Acute myeloid leukemia (AML) continues to have the lowest survival rates of all leukemias. Therefore, new therapeutic strategies are urgently needed to improve clinical outcomes for AML patients. Here, we report a novel role for Wilms’ tumor 1-associated protein (WTAP) in pathogenesis of AML. We have performed RNA-Seq in K562 cells with knockdown of WTAP to ascertain which genes it regulates. We have 2 replicates of total RNA for K562 cells and 2 replicates with WTAP knocked down
