[PDF][PDF] Loss of epigenetic information as a cause of mammalian aging

…, Z Dou, C Xu, SJ Mitchell, A Das, BL O'Connell… - Cell, 2023 - cell.com
All living things experience an increase in entropy, manifested as a loss of genetic and
epigenetic information. In yeast, epigenetic information is lost over time due to the relocalization …

Chromosome-scale shotgun assembly using an in vitro method for long-range linkage

NH Putnam, BL O'Connell, JC Stites, BJ Rice… - Genome …, 2016 - genome.cshlp.org
Long-range and highly accurate de novo assembly from short-read data is one of the most
pressing challenges in genomics. Recently, it has been shown that read pairs generated by …

Deeply conserved synteny and the evolution of metazoan chromosomes

…, F Marletaz, T Mitros, DT Schultz, BL O'Connell… - Science …, 2022 - science.org
Animal genomes show networks of deeply conserved gene linkages whose phylogenetic
scope and chromosomal context remain unclear. Here, we report chromosome-scale …

[HTML][HTML] Improved reference genome for the domestic horse increases assembly contiguity and composition

…, MS Hestand, JR Vermeesch, BL OConnell… - Communications …, 2018 - nature.com
Recent advances in genomic sequencing technology and computational assembly methods
have allowed scientists to improve reference genome assemblies in terms of contiguity and …

Natural selection shaped the rise and fall of passenger pigeon genomic diversity

…, PD Heintzman, B Letts, G McIntosh, BL O'Connell… - Science, 2017 - science.org
The extinct passenger pigeon was once the most abundant bird in North America, and possibly
the world. Although theory predicts that large populations will be more genetically diverse…

[HTML][HTML] High-throughput robust single-cell DNA methylation profiling with sciMETv2

RV Nichols, BL O'Connell, RM Mulqueen… - Nature …, 2022 - nature.com
DNA methylation is a key epigenetic property that drives gene regulatory programs in
development and disease. Current single-cell methods that produce high quality methylomes are …

High-content single-cell combinatorial indexing

RM Mulqueen, D Pokholok, BL O'Connell… - Nature …, 2021 - nature.com
Single-cell combinatorial indexing (sci) with transposase-based library construction increases
the throughput of single-cell genomics assays but produces sparse coverage in terms of …

Erosion of the epigenetic landscape and loss of cellular identity as a cause of aging in mammals

…, Z Dou, C Xu, JW Pippin, ML Creswell, BL O'Connell… - BioRxiv, 2019 - biorxiv.org
All living things experience entropy, manifested as a loss of inherited genetic and epigenetic
information over time. As budding yeast cells age, epigenetic changes result in a loss of cell …

Improved genome assembly of American alligator genome reveals conserved architecture of estrogen signaling

…, S Pham, J Howard, LF Lareau, BL O'Connell… - Genome …, 2017 - genome.cshlp.org
The American alligator, Alligator mississippiensis, like all crocodilians, has temperature-dependent
sex determination, in which the sex of an embryo is determined by the incubation …

Atlas-scale single-cell chromatin accessibility using nanowell-based combinatorial indexing

BL O'Connell, RV Nichols, D Pokholok… - Genome …, 2023 - genome.cshlp.org
Here we present advancements in single-cell combinatorial indexed Assay for Transposase
Accessible Chromatin (sciATAC) to measure chromatin accessibility that leverage nanowell …
