Embryonic stem cell potency fluctuates with endogenous retrovirus activity

TS Macfarlan, WD Gifford, S Driscoll, K Lettieri… - Nature, 2012 - nature.com
Embryonic stem (ES) cells are derived from blastocyst-stage embryos and are thought to be
functionally equivalent to the inner cell mass, which lacks the ability to produce all …

[HTML][HTML] Ten things you should know about transposable elements

…, M Imbeault, Z Izsvák, HL Levin, TS Macfarlan… - Genome biology, 2018 - Springer
Transposable elements (TEs) are major components of eukaryotic genomes. However, the
extent of their impact on genome evolution, function, and disease remain a matter of intense …

Transposable elements shape the evolution of mammalian development

AD Senft, TS Macfarlan - Nature Reviews Genetics, 2021 - nature.com
Transposable elements (TEs) promote genetic innovation but also threaten genome stability.
Despite multiple layers of host defence, TEs actively shape mammalian-specific …

Endogenous retroviruses and neighboring genes are coordinately repressed by LSD1/KDM1A

TS Macfarlan, WD Gifford, S Agarwal… - Genes & …, 2011 - genesdev.cshlp.org
Endogenous retroviruses (ERVs) constitute a substantial portion of mammalian genomes,
and their retrotransposition activity helped to drive genetic variation, yet their expression is …

[PDF][PDF] Long terminal repeats: from parasitic elements to building blocks of the transcriptional regulatory repertoire

PJ Thompson, TS Macfarlan, MC Lorincz - Molecular cell, 2016 - cell.com
The life cycle of endogenous retroviruses (ERVs), also called long terminal repeat (LTR)
retrotransposons, begins with transcription by RNA polymerase II followed by reverse …

Enhancer priming by H3K4 methyltransferase MLL4 controls cell fate transition

…, JE Lee, B Lai, TS Macfarlan, S Xu… - Proceedings of the …, 2016 - National Acad Sciences
Transcriptional enhancers control cell-type–specific gene expression. Primed enhancers
are marked by histone H3 lysine 4 (H3K4) mono/di-methylation (H3K4me1/2). Active …

The KRAB zinc finger protein ZFP809 is required to initiate epigenetic silencing of endogenous retroviruses

…, AL Nielsen, FS Pedersen, TS Macfarlan - Genes & …, 2015 - genesdev.cshlp.org
Retroviruses have been invading mammalian germlines for millions of years, accumulating
in the form of endogenous retroviruses (ERVs) that account for nearly one-tenth of the mouse …

The role of KRAB-ZFPs in transposable element repression and mammalian evolution

P Yang, Y Wang, TS Macfarlan - Trends in Genetics, 2017 - cell.com
Kruppel-associated box zinc-finger proteins (KRAB-ZFPs) make up the largest family of
transcription factors in humans. These proteins emerged in the last common ancestor of …

TRIM28 repression of retrotransposon-based enhancers is necessary to preserve transcriptional dynamics in embryonic stem cells

…, L Fasching, TS Macfarlan, Y Tarabay, S Viville… - Genome …, 2013 - genome.cshlp.org
TRIM28 is critical for the silencing of endogenous retroviruses (ERVs) in embryonic stem (ES)
cells. Here, we reveal that an essential impact of this process is the protection of cellular …

Transposable elements as genetic regulatory substrates in early development

WD Gifford, SL Pfaff, TS Macfarlan - Trends in cell biology, 2013 - cell.com
The abundance and ancient origins of transposable elements (TEs) in eukaryotic genomes
has spawned research into the potential symbiotic relationship between these elements and …
