Group leader @igbmc.bsky.social interested in chromatin and cell fate decisions | Former postdoc in Adrian Bird's lab (University of Edinburgh) https://www.igbmc.fr/en/recherche/teams/genomic-and-epigenomic-regulation-of-cell-fate

A massive update: At least ~15 companies~ are selling scientists antibodies using faked validation data. We've documented 18,000+ manipulated images on 17,000+ products sold by leading laboratory suppliers including Thermo Fisher, Abcam, Santa Cruz Biotechnology, Millipore Sigma and Bio-Techne. 1/🧵

1/🧵 Can transcription factor condensate formation be explained without phase separation? Our new preprint introduces SPARK, a simulation tool that reproduces condensate behavior (clustering, fusion, FRAP) from diffusion & binding kinetics alone.

Much enjoyed this nice cryoEM study of NONO:SFPQ heterocomplex this morning, while it was snowing outside. So happy to read a paper in full again (only a handful of papers read in full in last weeks or even months ☹, and some were to review).

Filament formation of full-length NONO/SFPQ heterodimers was observed and structurally characterized in vitro which may provide a scaffold for gene regulation, paraspeckle formation and DNA double-str...

Excited to announce I recently highlighted another preprint for @prelights.bsky.social. In this preprint, @r-pantier.bsky.social and co-authors from the Chambers Lab at the University of Edinburgh find that the TET proteins act together to help mammalian cells specify into somatic lineages.

TET knockout cells transit between pluripotent states and exhibit precocious germline entry - preLights

Genetic gatekeepers of gametogenesis? TET proteins jointly jam germline specification, synergistically steering cells towards somatic fates.
