🩸🧬 Delighted to share our new @nature.com paper! Genetic studies of >28,000 people reveal a BACH2-NRF2 pathway for activating fetal hemoglobin, suggesting new tx avenues for sickle cell disease & β-thalassemia. Led by the amazing Chun-Jie Guo & co! www.nature.com/articles/s41...

Human genetics implicates a BACH2–NRF2 axis in fetal haemoglobin activation - Nature
BACH2 restrains activation of the fetal-haemoglobin-encoding γ-globin genes, while loss of BACH2 enhances NRF2 chromatin occupancy and promotes the formation of activation foci at the γ-globin genes.

Exited to share our recent work on viral cis-regulatory elements in collaboration with @tewhey.bsky.social! We identified >2000 CREs across the genomes of 27 human-infecting dsDNA viruses from the Herpesvirus, Adenovirus, Papillomavirus, and Polyomavirus families. www.biorxiv.org/content/10.1... 1/8

Proud to share our lab’s first student preprint!🚀@j-c-butts.bsky.social, @alwaysrong.bsky.social, @sagergosai.bsky.social leveraged our MPRA models to predict variant effects, providing scores for the complete catalog of human variation. Grateful for another fun collab with @stevereilly.bsky.social.

In 15 yrs of reporting, I've never had so many health & biomed researchers & outreach orgs tell me they're afraid to talk w/press or barred from speaking bc of new comms policies. I understand the fear of losing funds. I don't know if silence does more harm than good. If you can speak up, pls do.

Super excited to announce our latest flagship model Borzoi: major props to Johannes & David Kelley et al for advancing it. It's been a long journey from our prior Enformer model into this one. A few innovations: i) longer DNA context, ii) adaptation to predict RNA-seq abundance and splice isoforms,

Predicting RNA-seq coverage from DNA sequence as a unifying model of gene regulation - Nature Genetics
Borzoi adapts the Enformer sequence-to-expression model to directly predict RNA-seq coverage, enabling the in-silico analysis of variant effects across multiple layers of gene regulation.
