Great start of the #CABDseminars 2025/2026 with the talk of Miguel Rodriguez de los Santos!

Dr. Rodriguez gave an insight of the studies from his PhD and Postdoc work focused on rate diseases. He was invited by @crisprscan.bsky.social!

Thanks for coming Miguel!

Teaching biology in the old days relied on large posters. Often beautiful and poetic art pieces. When a chair of @genevunige.bsky.social dept, in Geneva, we digitalised our huge collection (catalogue raisonné). Why? I dont' know. The strange feeling these things should not disappear. Yet they will.

PRC2 silences genes by adding H3K27me3 at the right spots in the genome. Our model shows how the nucleic acid-binding domain (NBD) of SUZ12 keeps this activity under control, and what happens when you remove it.

our work on the molecular differences between transcription factor isoforms is out now in Molecular Cell!

key point: 2/3rds of TF isos differ in properties like DNA binding & transcriptional activity

many are "negative regulators" & misexpressed in cancer
