Depletion of MALAT1-dependent WTAP reduces aggressiveness of hypoxic TNBC cells

Project description:Numerous studies have identified long non-coding RNAs (lncRNA) as critical players in regulating tumor progression and metastasis formation. Here, we show that MALAT1 in hypoxic conditions, positively regulates WTAP protein expression, which influences the response to hypoxia by favoring the transcription of the master regulators HIF1A and HIF1B. Furthermore,WTAP stimulates BC cell migratory ability and the expression of N-Cadherin and Vimentin, hallmarks of epithelial-to-mesenchymal transition (EMT)

Exogenous SLFN12 reduces in vivo TNBC proliferation and invasion, increases luminal markers and a gene signature that reducts better breast cancer survival in cohort database analysis

Project description:Our results suggest that increased SLFN12 expression modulates TNBC aggressiveness through a gene signature which could offer new targets for treatment.

Binding motif analysis of METTL3，WTAP in METTL3，WTAP overexpressed Human 293T cells

Project description:label the cells overexpressed Myc tagged METTL3 and Flag tagged WTAP with 4-SU, the RNA bound by METT3,WTAP can be got by Myc or Flag IP followed by RNA isolation by using the TRIzol (Invitrogen) reagent by following the company manual.the RNA was then used for library preparation using a TruSeq™ RNA Sample Prep Kit v2 (Illumina, San Diego, CA, USA) according to the manufacturer’s protocol.The libraries were sequenced using HiSeq2000 (Illumina) in single-read mode, creating reads with a length of 50 bp. Sequencing chemistry v2 (Illumina) was used and samples were multiplexed in two samples per lane. discovery of the binding motif of METTL3，WTAP in METTL3，WTAP overexpressed Human 293T cells

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.

Differential Gene expression in the mouse mammary tumors of PyMT-Malat1 wild-type (WT), PyMT-Malat1 knockout (KO) and PyMT-Malat1 knockout with Malat1 transgene expression (TG)

Project description:Previously, lncRNA Malat1 knockout mice were generated by insertional inactivation. By crossing this line to MMTV-PyMT mammary tumor mouse model, we produced PyMT;Malat1 wild-type (WT) and PyMT;Malat1 knockout (KO). Furthermore, we generated Malat1 transgenic mice by targeting ROSA26 locus and bred them to PyMT;Malat1 knockout mice to produce Malat1-rescued PyMT;Malat1 knockout;Malat1 transgenic animals (TG). Using mammary tumors from the three groups of animals, we performed RNA-Seq analysis to identify differentially up-regulated genes in KO tumors to find novel target genes of YAP-TEAD pathway.

WTAP-induced change in gene expresssion in cholangiocarcinoma cells

Project description:Knock-down or overexpression of WTAP regulated migration and invasion of cholangiocarcinoma cells in vivo and vitro studies. To investigate the underlying mechanism for WTAP-regulated migration and invasion, the gene expression between the mock cells and the stable cells was compared Total RNA was purified from the mock cells and the stable cells overexpressing WTAP

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
