Super excited to share our latest #preprint on the TE classification/annotation and regulatory evolution from our lab @guilbourque at @Ashbi_KyotoU. Check it out here! 🧵 Cryptic endogenous retrovirus subfamilies in the primate lineage doi.org/10.1101/2023.1…

New preprint from our lab! Why is not everyone working on Transposons? Loss of H3K9me3 maintenance in human neural progenitor cells leads to transcriptional activation of L1 retrotransposons biorxiv.org/content/10.110…

@CedricFeschotte @sylviaandbu @JN_Wells Amazing story, congrats!

💥Our new preprint! Transposon ADDICTION in development! Gag proteins of endogenous retroviruses are required for zebrafish development Study led heroically by @sylviaandbu & @JN_Wells This work has transformed my view of transposons, no less! 🧵1/n biorxiv.org/content/10.110…

Why don't humans have tails? A genetics study finds that a mobile genetic sequence inserted into a gene for tail development contributed to tail loss as early apes evolved. go.nature.com/3Te8t4C

Locus-level L1 DNA methylation profiling reveals the epigenetic and transcriptional interplay between L1s and their integration sites dlvr.it/T2DH8X

Our paper on the ancestral genome-assisted TE annotation method/resource is out in @CellGenomics! Enhanced annotation is now available for multiple species, including human and mouse, with ~70% increase in ancient TEs. cell.com/cell-genomics/…

@guilbourque @groza_cristian Congrats @guilbourque and @groza_cristian!

#Pangenome graphs improve the analysis of SVs for rare genetic diseases. Our new study is out! Great collaboration with the lab of Tomi Pastinen and congrats to @groza_cristian for the amazing work! nature.com/articles/s4146…

@manvendr7 @TheNixonLab @CedricFeschotte Congrats @manvendr7. Very cool story!

🎈🎆Beyond thrilled to drop new preprint exploring how #transposons (TEs) contribute to natural resistance to HIV in “Elite Controllers” (ECs) biorxiv.org/content/10.110… a work from @TheNixonLab and @CedricFeschotte Lab Please see 🧵till end, it gets better with each 🧵 1/12

💥 New preprint! Really excited about this work brilliantly led by Manu @manvendr7 & Sabrina Leddy in collab with @TheNixonLab - check it out and let us know what you think!

@manvendr7 @guilbourque @Ashbi_KyotoU Thanks @manvendr7

@xunchen85 @guilbourque @Ashbi_KyotoU Super nice! Congratulations to all involved!
