讲座内容简介:

Over 150 types of post-transcriptional RNA modifications have been identified in all kingdoms of life. We have discovered two RNA demethylases, FTO and ALKBH5, which catalyze oxidative demethylation of the most prevalent modifications of mammalian messenger RNA (mRNA) and other nuclear RNA, N6-methyladenosine (m6A). These findings indicate that reversible RNA modification could impact biological regulation analogous to the well-known reversible DNA and histone chemical modifications. We have also characterized proteins that selectively recognize m6A-modified mRNA and affect the translation status and lifetime of the target mRNA. Functional studies reveal m6A methylation as a critical mechanism to group transcripts for coordinated metabolism, translation, and decay, allowing timely and coordinated protein synthesis and transcriptome switching during cell differentiation and development. I will also present the most recent advance on chromatin and transcription regulation by RNA methylation and demethylation.
