Transcriptomic RNA structure mapping unveils the structure dynamic induced by DHX36 binding (Structure-seq)

Project description:RNA binding proteins can modulate RNA secondary structures, thus participating in post-transcriptional regulation. The DEAH-box helicase 36 (DHX36) has a remarkable ability to bind and unwind RNA G-quadruplex (rG4) and duplex. However, the transcriptome-wide RNA structure dynamic induced by DHX36 and how structure change subsequently influences RNA fate remain poorly understood. Here, we first identify the endogenous binding sites and specificity of DHX36 based on binding profiles. Next, we capture in vivo RNA structuromes to investigate the structure change of DHX36-bound mRNAs following DHX36 knockout. DHX36 induces structure remodeling on not only the localized binding sites but also the other sites across the entire mRNA especially in 3’UTR. DHX36-induced more accessible structures of 3’UTR are revealed to correlate with post-transcriptional mRNA decrease. Furthermore, we demonstrate that DHX36 binding sites are enriched for N6-methyladenosine (m6A) modification and YTHDF1 binding. Finally, we experimentally validate that YTHDF1 binding is repelled to DHX36 loss-induced structure inaccessibility and YTHDF1 loss-induced mRNA stabilization could be a source of DHX36 loss-induced mRNA increase. Altogether, our findings uncover the effect of DHX36 binding on in vivo mRNA structure and propose a plausible mechanism of how RNA secondary structure change involves in post-transcriptional regulation through orchestrating YTHDF1 binding.

DHX36 binding induces RNA structurome remodeling and regulates RNA abundance via m6A/YTHDF1

Project description:RNA structure constitutes a new layer of gene regulatory mechanisms. RNA binding proteins can modulate RNA secondary structures, thus participating in post-transcriptional regulation. The DEAH-box helicase 36 (DHX36) is known to bind and unwind RNA G-quadruplex (rG4) structure but the transcriptome-wide RNA structure remodeling induced by DHX36 binding and the impact on RNA fate remain poorly understood. Here, we investigate the RNA structurome alteration induced by DHX36 depletion. Our findings reveal that DHX36 binding induces structure remodeling not only at the localized binding sites but also on the entire mRNA transcript most pronounced in3’UTR regions. DHX36 binding increase structural accessibility at 3’UTRs which is correlated with decreased post-transcriptional mRNA abundance. Further analyses and experiments uncover that DHX36 binding sites are enriched for N6-methyladenosine (m6A) modification and YTHDF1 binding; and DHX36 induced structural change may facilitate YTHDF1 binding to m6A sites leading to RNA degradation. Altogether, our findings uncover the structural remodeling effect of DHX36 binding and its impact on RNA abundance through regulating m6A dependent YTHDF1 binding.

Rapid degradation of DHX36 revealing its transcriptional role by interacting with G-quadruplex

Project description:More evident supports G-quadruplex are involved in transcription. Recent research revealed that DHX36 preferentially resolves G-quadruplex (G4) structure over the canonical G4, raising the possibility that DHX36 could bind and resolve G4 structures to regulate gene transcription. However, the hypothesis has yet been validated systematically in vivo.In this study, we investigated the role of DHX36 interacting with G4s in transcription. Firstly, we performed CUT&TAG to map the binding sites in chromatin of MCF7. Next, we utilized nascent RNA-seq and AID protein degradation system to identify the direct gene targets by transcriptional regulation of DHX36 and found these sites are enriched with G4 structure. We picked three G4 sequences in oncogene from these sites and found DHX36 binds and resolves these G4 structures in vitro, suggesting DHX36 may be recruited to these promoter G4 sites and regulate gene transcription by resolving G4 structure.

System-wide analysis of Dhx36 function in skeletal muscle satellite cells reveals its binding with 5’UTR G4 structure to promote Gnai2 RNA translation

Project description:In this study, we deciphered the functions of Dhx36 and related molecular mechanisms in muscle stem cells and muscle regeneration. We found Dhx36 was highly induced in activated muscle stem cells during regeneration induced by injury. Conditional inactivation of Dhx36 in mouse muscle stem cells caused significant impaired regeneration, which was due to the dramatically decreased cell proliferation. Dhx36 was a well-known RNA helicase for binding/unwinding DNA/RNA G-quadruplexes and it was dominantly expressed in cytoplasm of proliferating myoblast. CLIP-seq was conducted to identify the mRNAs interacting with Dhx36 in myoblast cells. To examine whether Dhx36 regulates translation process, we also conducted polysome profiling followed by RNA-seq in WT and Dhx36 KO myoblast cells. This SuperSeries is composed of the SubSeries listed below.
