Mapping nucleolus-associated chromatin interactions by nucleolus-Hi-C reveals repression network
Active DNA demethylation in mammals involves TET-mediated oxidation of 5-methylcytosine (5mC) to 5-hydroxymethylcytosine (5hmC), 5-formylcytosine (5fC) and 5-carboxycytosine (5caC). However, genome-wide detection of 5fC at single-base resolution remains challenging. Here we present a bisulfite-free ...

Single-Cell 5-Hydroxymethylcytosine Landscapes of Mammalian Early Embryos at Single-Base Resolution
Pseudouridine (Ψ) is the most abundant RNA modification, yet little is known about its content, dynamics and function in mRNA and ncRNA. Here, we perform quantitative MS analysis and develop CAP-seq for transcriptome-wide Ψ profiling. The unexpected high Ψ content (Ψ/U ratio: ~ 0.2% to 0.6%) indicat...

N1-methyladenosine (m1A) is an abundant post-transcriptional RNA modification, yet little is known about its prevalence, topology and dynamics in mRNA. Here, we show that m1A is abundant in human mRNA, with an m1A/A ratio of ~0.02%. We develop m1A-ID-Seq, based on m1A immunoprecipitation and the in...

In order to identify the molecular mechanism leading to the increase of TRMT6/61A complex in aged HSCs, we purified proteins interacting with TRMT6 and TRMT61A via affinity purification. HEK293T cells stably expressing SFB-tagged TRMT6 or SFB-TRMT61A were lysed in NETN buffer (20 mM Tris-HCl [pH 8.0...
