RNA demethylase ALKBH5 promotes tumorigenesis in multiple myeloma [m6A-seq]

Project description:We here report ALKBH5, a m6A RNA demethylase, as a crucial oncogene in multiple myeloma (MM). Using various MM models, we demonstrated a critical requirement of ALKBH5 for MM cell proliferation in vitro and in vivo. To identify the potential mRNA targets of ALKBH5, we conducted m6A-seq with mRNA samples enriched from MM cells with or without ALKBH5 knockdown.

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

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.
