RBM33 Acts as an m6A Reader Essential for ALKBH5-mediated m6A Demethylation and Head and Neck Squamous Carcinoma Tumorigenesis [m6A-seq]

Project description:Head and neck squamous cell carcinoma (HNSC) is one of the most common malignant cancers worldwide. However, it is always detected at an advanced stage because of a lack of biomarkers for early diagnosis. Here, we identify the RNA binding motif protein 33 (RBM33) is commonly up-regulated in HNSC and it is essential for tumorigenesis. Mechanistically, RBM33 is an m6A reader protein and forms a complex with ALKBH5. RBM33 plays crucial roles in ALKBH5-mediated mRNA m6A demethylation not only by recruitment ALKBH5 to substrate but also activation its demethylase activity through inhibition it’s SUMOylation. Moreover, global transcriptomic and epitranscriptomic analyses identify that DDIT4 is a functional downstream target gene for RBM33 in HNSC and RBM33-mediated HNSC tumorigenesis by inhibition the mTOR pathway through the inhibition of m6A-dependent DDIT4 mRNA decay. Taken together, our study uncovers a novel molecular mechanism that RBM33/ALKBH5/m6A/DDIT4/mTOR axis regulates HNSC progression through the inhibition of mTOR pathway and targeting RBM33 may be a promising strategy for HNSC treatment.

ENO1's RNA-binding sites in Human HeLa cells using eCLIP

Project description:eCLIP was performed for ENO1 in HeLa cells, following the protocol described by Van Nostrand et al. (2016). Libraries for six immunoprecipitation and size-matched input controls were produced. In addition, libraries were produced for two no-crosslinking controls. The libraries were sequenced using paired-end sequencing (PE125) on an Illumina HiSeq2000 platform.

Enhanced CLIP uncovers IMP protein-RNA targets in human pluripotent stem cells important for cell adhesion and survival [eCLIP-Seq]

Project description:Human pluripotent stem cells (hPSCs) require precise control of post-transcriptional RNA networks to maintain proliferation and survival. Using a recently developed enhanced UV crosslinking and immunoprecipitation (eCLIP) approach, we identify RNA targets of the IMP/IGF2BP family of RNA-binding proteins in hPSCs. At the broad region- and binding site-level IMP1 and IMP2 show reproducible binding to a large and overlapping set of 3'UTR-enriched targets. RNA Bind-N-Seq applied to recombinant full-length IMP1 and IMP2 reveals CA-rich motifs that are enriched in eCLIP-defined binding sites. We observe that IMP1 loss in hPSCs recapitulates IMP1 phenotypes, including a reduction in cell adhesion and an increase in cell death. For cell adhesion, in hPSCs we find IMP1 maintains levels of integrin mRNA, specifically regulating RNA stability of ITGB5. Additionally, we show IMP1 can be linked to hPSC survival via direct target BCL2. Thus, transcriptome-wide binding profiles identify hPSC targets modulating well-characterized IMP1 roles. eCLIP-seq was performed in biological replicate for IGF2BP1/IMP1 and IGF2BP2/IMP2, as well as one replicate each for IGF2BP3/IMP3, RBFOX2, and an IgG control. Each sample has a size-matched input control for analysis
