📖 Happy to share our recent preprint! www.biorxiv.org/content/10.1... We discovered how SINEs are kept silent: the ChAHP protein complex acts as a molecular brake on POL III transcription retrotransposons. A 🧵:
ChAHP Silences SINE Retrotransposons by Inhibiting TFIIIB Recruitment
Short interspersed nuclear elements (SINEs) are abundant non-autonomous transposable elements derived from RNA polymerase III (POL III)-transcribed short non-coding RNAs. SINEs retain sequence feature...

☕Earl Grey v7.0.0 brewed fresh☕

Nested TEs finally get the treatment they deserve: iterative detection of deep nesting, cleaner GFF annotations, and coverage stats that don’t double-count genomic space + a RepeatCraft edge-case fix.

Happy new year to the TE folks! 🧬

Characterization of RNA interference in the cnidarian Nematostella vectensis reveals partial target silencing but lack of small RNA amplification
RNA interference is an ancestral antiviral mechanism that degrades viral RNA through siRNAs, but its role in cnidarians has been unclear. This study shows that Nematostella vectensis likely possesses ...

Modern biology research is biased towards investigating genes that are widely conserved and present in humans. What about genes that ARE widely conserved but NOT present in humans? Can genes missing from humans tell us something about what makes our biology different from that of other animals? 1/8

Do transcriptional activators work on any promoter? Our data says no. 🙅‍♂️
Despite driving ~2/3 of mammalian genes, CpG island (CGI) promoters have remained a puzzle. We identified >50 activators that are exclusively compatible with this promoter class. 🧬

Intrigued by a long-standing conundrum in small RNA biology—how nuclear Argonaute proteins silence transposons when they *need* target transcription for their own recruitment—we studied the piRNA pathway.

And found a hidden RNA-decay axis from Piwi to the RNA exosome.
RNA decay via the nuclear exosome is essential for piwi-mediated transposon silencing https://www.biorxiv.org/content/10.64898/2025.12.16.694471v1
