New preprint from the lab! We dig into the regulatory roles of TEs in the mouse placenta, with some surprising findings. Led by the awesome @smamante.bsky.social. Particular kudos to him for navigating the many twists and turns of the project.

The speed at which Oxford Nanopore is cancelling support for their devices is just mind boggling 😳
P2 solo will be decommissioned soon!!! This is not sustainable!
@nanoporetech.com

Sad to hear that Oxford Nanopore wants to discontinue the P2Solo later this year in favor of the P2i (the very pricey P2Solo that comes with a GPU to do the basecalling in it)

It feels like such a big step in the wrong direction. They are a great sequencing company, not a great GPU upseller...

Pervasive cis-regulatory co-option of a transposable element family reinforces cell identity across the mouse immune system Transposable elements (TEs) make up about half of the human and mouse genomes and play important regulatory roles in immune responses. However, the cis -regulatory contribution of TEs to immune cell d...

Epigenetic lockdown of type I interferon sensing and signalling in human pluripotent cells. The Human Silencing Hub (HUSH) complex safeguards genome integrity in human somatic cells by repressing transposable elements and regulating type I interferon (IFN-I) induction. In early development, ...

How do pluripotent stem cells resist harmful interferon responses to safeguard development? Through total epigenetic lockdown of ligands, sensors and effectors of IFN-I. In our preprint, James Holt shares his PhD discoveries on the ground state of immune evasion 😊: www.biorxiv.org/cgi/content/...

LINE-1 retrotransposons mediate cis-acting transcriptional control in human pluripotent stem cells and regulate early brain development Adami et al. demonstrate that evolutionarily young L1s are expressed in human pluripotent stem cells and are dynamically regulated throughout neural differentiation. The study examines the role of L1s...

New paper from our lab! We found that LINE-1 transposons contribute to early human brain development.
