Dual native G‐quadruplex folding is associated with chromatin looping at the MYC locus
FEBS Open Bio, EarlyView.BG4‐detectable G‐quadruplex (G4) in HaCaT and NHEK keratinocytes identified folded and unfolded G4s enriched at promoters/TSSs and active enhancers, whereas unfolded G4s also overlapped weak/poised enhancers. At MYC–PVT1, 3C‐qPCR detected enhancer–promoter looping only when G4s were simultaneously folded at both regulatory elements under native ...

eLife, 2016 We recently found that nucleosomes directly block access of CRISPR/Cas9 to DNA (Horlbeck et al., 2016). Here, we build on this observation with a comprehensive algorithm that incorporates chromatin, position, and sequence features to accurately predict ...

Chemistry & Biology, 2010 In order to form a covalent complex with DNA inside human cells, cisplatin has to overcome the protective environment of a nucleosome, where DNA is complexed with histone proteins. Todd and Lippard (2010) expand our understanding of this process by describing the structure of a nucleosome containing a Pt-DNA adduct, which has important implications for

Average level of nucleosomes vs. .
, 2013 The average level of nucleosomes is plotted as a function of for both and . These levels of nucleosomes are computed by averaging the final number of nucleosomes in the simulations over all the runs and the whole lattice.

Consensus Formation and Change are Enhanced by Neutrality
Advanced Science, EarlyView.Neutral agents are shown to enhance both the formation and overturning of consensus in collective decision‐making. A general mathematical model and experiments with locusts and humans reveal that neutrality enables robust consensus via simple interactions and accelerates consensus change by reducing effective population size.

Charting Endocrine Progenitors Across Species and Organs
Advanced Science, EarlyView.Endocrine progenitors give rise to the hormone‐producing cells of the pancreas and intestine. Using single‐cell multiomics and proteomics, this study compares these progenitors across species, systems, and organs, mapping the conserved and species‐specific gene regulatory networks that guide their formation.

Rate heterogeneity of nucleosomes spanning splicing sites.
, 2013 The substitution (A) and indel (B) rates increase from the exonic end of nucleosomes to intronic sites as nucleosomes protrude into introns, and reach the maximum at the linker regions within introns.

TED1 Promotes the Assembly of SCFD3‐D14‐D53 to Reinforce Strigolactone Signaling in Rice
Advanced Science, EarlyView.This study identifies TED1 as a positive regulator of strigolactones (SL) signaling in rice. The ted1 mutants display dwarfism and increased tillering with significantly reduced SLs sensitivity. Through its longer C‐terminal region, TED1 interacts with D53 and D14 to promote the assembly of SCFD3‐D14‐D53, thereby facilitating the efficient ...
