ALKBH5 promotes tumor progression by decreasing RIG-I expression mediated by N6-methyladenosine-dependent HNRNPC binding in HNSCC [MeRIP-seq]

ABSTRACT: To determine the targets underlying ALKBH5 during head and neck squamouse cell carcinoma progression, Methylated RNA immunoprecipitation (MeRIP) with an m6A specific antibody followed by RNA sequencing (MeRIP-seq) and next generation sequencing were combined to screen the potential targets haboring m6A modificatios and mRNA level alteration after ALKBH5 knockdown in a HNSCC cell line.

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

Genome-wide maps of m6a state in RA FLSs with or without ALKBH5 knockdown.

Project description:To investigate how ALKBH5 modulates RA FLSs functions, we conducted m6A sequencing (MeRIP-seq) of RA FLSs. Consistent with previous studies, in both scramble controls and ALKBH5 knockdown cells, m6A modifications were highly enriched within the GGAC motif. m6A peaks are located mainly in the protein-coding region (CDS) and 3’ untranslated region (3’ UTR) of mRNA transcripts

The interacted proteins of ALKBH5 and FTO identified by IP-mass

Project description:Since m6A demethylases (FTO and ALKBH5) have been reported to be involved in pre-mRNA splicing regulation, we hypothesized that dynamic m6A distribution during mRNA maturation might involve removal of m6A in internal exons by FTO or ALKBH5 accompanied by splicing factors. To explore this we performed pull-down assays coupled with protein mass spectrometry.
