Protocol for efficient CRISPRi-mediated silencing of retrotransposons in human pluripotent stem cells Here, we present a workflow for transcriptional silencing of transposable elements (TEs) in human induced pluripotent stem cells (hiPSCs). We describe steps for designing guide RNAs (gRNAs) to target ...

Are you interested in achieving efficient silencing of transposable elements using CRISPRi? 🧬 🧫
Go ahead and have a look at this STAR protocols where Adami et al. share all the tips & tricks they use in the Jakobsson lab.

Key findings:

1️⃣ L1s drive large-scale rearrangements including translocations (not just insertions)

2️⃣ Frequency of these events was largely underestimated by short-reads

3️⃣ They occur EARLY, thus potentially acting as drivers

Concurrent L1 retrotransposition events promote reciprocal translocations in human tumorigenesis LINE-1 (L1) retrotransposition generates somatic genomic variation in human cancer, but short-read sequencing has limited our understanding of its structural consequences and dynamics. Using long-read...

A reference-free pipeline for detecting shared transposable elements from pan-genomes to retrace their dynamics in a species - Genome Biology Background The role of transposable elements (TEs) in host adaptation has gained interest in recent years. Individuals of the same species undergo independent TE insertions, providing genetic variabil...

🚨 New paper alert on telomeres! 🚨
Something different from the group! Thanks to Yuxin, a talented student in the lab, we used long-reads in 75 human trios to study telomeres and their inheritance.

It was fun to write this preview with Larisa Okorokova. Congrats to @jakobssonlab.bsky.social and all coauthors for this nice piece of work !
