Project description:SETD2 is the specific methyltransferase of H3K36me3, while METTL3, METTL14 and WTAP are the components of m6A methyltransferase complex. To understand the global effect of H3K36me3 on m6A modification, we compared the m6A profiling in SETD2 and METTL3, METTL14 or WTAP knockdown HepG2 cells, and found depletion of H3K36me3 by SETD2 silencing globally reduced m6A in human transcriptome. What’s more, most of the SETD2-dependent hypomethylation sites also responded to knockdown of METTL3, METTL14, or WTAP.

Project description:N6-methyladenosine (m6A) methylation of mRNA by the methyltransferase complex (MTC), with core components including METTL3-METTL14 heterodimers and Wilms’ tumor 1-associated protein (WTAP), contributes to breast tumorigenesis, but the mechanism of MTC assembly remains elusive. Here, we identify a novel cleaved form METTL3a (residues 239-580 of METTL3), that is highly expressed in breast cancer. Furthermore, we find that both METTL3a and full-length METTL3 are required for MTC assembly, RNA m6A deposition, as well as cancer cell proliferation. Mechanistically, we find that METTL3a is required for METTL3-METTL3 interaction, which is a prerequisite step for recruitment of WTAP in MTC assembly. Analysis of m6A sequencing data shows that depletion of METTL3a globally disrupts m6A methylation, and METTL3a mediates mTOR activation via m6A-mediated suppression of TMEM127 expression. Consequently, we find that METTL3 cleavage is mediated by proteasome in an mTOR-dependent manner, revealing positive regulatory feedback between METTL3a and mTOR signaling. Our findings reveal METTL3a as an important component for MTC assembly, and suggest the METTL3a-mTOR axis as a potential therapeutic target for breast cancer.

Project description:RNA was isolated from and METTL3，WTAP deficient Human HeLa cells using the TRIzol (Invitrogen) reagent by following the company manual. For all samples the RNA integrity was checked using an Agilent Bioanalyzer 2100. All samples showed a RIN (RNA integrity number) of higher than 9. Approximately 2.5 µg of total 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.

Project description:The Wilms tumor 1 (WT1)-associated protein (WTAP) is upregulated in many tumors, including, acute myeloid leukemia (AML), where it plays an oncogenic role by interacting with different proteins involved in RNA processing and cell proliferation. In addition, WTAP is also a regulator of the nuclear complex required for the deposition of N6-methyladenosine (m6A) into mRNAs, containing the METTL3 methyltransferase. However, it is not clear if WTAP may have m6A-independent regulatory functions that might contribute to its oncogenic role. Here, we show that both knockdown and overexpression of METTL3 protein results in WTAP protein upregulation, indicating that METTL3 levels are critical for WTAP protein homeostasis. However, we show that WTAP upregulation is not sufficient to promote cell proliferation in the absence of a functional METTL3. Therein, these data indicate that the reported oncogenic function of WTAP is strictly connected to a functional m6A methylation complex.

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.

Project description:We performed immunoprecipitation of m6A-modfiied poly-A tailed RNA in mouse ESCs expressing either wild-type or non-phosphorylatable METTL3/WTAP. By sequencing over 4 billion bases across both Input and Immunoprecipitated (IP) samples, we generate a transcriptome-wide map of m6A methylation enrichment across both cell types. We find that m6A peaks that are differentially methylated between R-WT and R-3A2A mouse ESCs. Several pluripotency transcripts show reduced m6A methylation in R-3A2A cells compared to R-WT. For the CRISPR screen, we transduced a circular RNA GGACU-containing GFP reporter plasmid, followed by transduction of a genome-wide CRISPR sgRNA library. We selected for the top and bottom 5% of GFP expression in HeLa cells and sequenced the sgRNAs.
