Thrilled to see this published today! Truly special because we made the initial discovery >15 yrs ago! We found two copies of a human gene called BC200 embedded in a human poxvirus. BC200 blurs the line between gene & transposon—both functional & mutagenic! www.science.org/doi/10.1126/... 🧵1/n

Escape of the BC200 gene to a human poxvirus reveals its persistent transposition in primates
Transposable elements mobilize within and occasionally between genomes, including from host to virus. We identified two insertions of the human BC200 noncoding RNA gene in the poxvirus molluscum conta...

Super excited to share my postdoctoral work at @imbavienna.bsky.social @viennabiocenter.bsky.social - We discovered that some retrotransposons, or "jumping genes" 🧬, are able to spread from cell to cell via a new viral infectivity route. A short thread: 🧵👇 (1/7)

Finally - the 🧵! So, the piRNA pathway defends the animal germline from transposons. But most of what we know comes from narrow developmental windows like late oogenesis, where it's easiest to study. We asked if the pathway is the same across development. It is not! /+
