Thank you, @philipcball.bsky.social ! It was a pleasure to meet you in person!

Lou Gehrig’s courage brought ALS to national attention. On Lou Gehrig Day, we honor his legacy. Join Target ALS and #PacBio in an upcoming webinar to learn how long-read sequencing is powering the largest ALS genomics study to date.

Congrats! It’s on my reading list!

Neuronal aging causes mislocalization of splicing proteins and unchecked cellular stress - Nature Neuroscience Rhine et al. find that neuronal aging leads to widespread dysregulation of RNA biology, including mislocalization of splicing proteins like TDP-43, chronic cellular stress and reduced resiliency.

Excited to share my postdoctoral research on how neuronal #aging contributes to RNA dysfunction is now online at Nature Neuroscience! Here we find that aged neurons suffer from chronic cellular stress that compromises resiliency to new stressors🧪 www.nature.com/articles/s41...

Happy to be back for graduation! Thankful for my mentor @bsabari.bsky.social , @utswtxid.bsky.social and family/friends who were there last night! 🙏🏼

An intrinsically disordered region mediates RNA-binding selectivity and pro-oncogenic activities of LARP6 Intrinsically disordered regions (IDRs) are prevalent in RNA-binding proteins (RBPs), yet their roles in RNA interactions remain poorly defined. Here, we examined the structured and disordered RNA-bin...

🚨Check out our significantly updated preprint, now out on @biorxivpreprint.bsky.social. Together with Sasi Conte lab, we characterize a novel role for intrinsically disordered regions (IDRs) in promoting RNA-binding selectivity in RNA binding proteins (RBPs): www.biorxiv.org/content/10.1...

Protein organ clocks, as assessed in over 6,000 people (~4,000 plasma proteins, 8 organs) with 20-year follow-up are predictive for over 30 age-related diseases

Neuronal polyunsaturated fatty acids are protective in ALS/FTD Nature Neuroscience - Lipidomics revealed that neurons of patients with ALS/FTD have reduced levels of polyunsaturated fatty acid (PUFA)-containing phospholipids. Increasing neuronal PUFA levels...

Really excited this is out! We found polyunsaturated fatty acids (PUFAs) were beneficial in models of C9orf72 FTD/ALS and the greatest benefit occurred when increasing levels specifically within neurons @ukdri.ac.uk @uclqsion.bsky.social @ucl.ac.uk @cziscience.bsky.social

RNA polymerase II coordinates histone deacetylation at active promoters Transcription initiation limits histone acetylation and H2AZ incorporation at promoters.

Unpause! I'm super happy to now be able to share the published version of our paper at Science Advances showing that:
1) active histone mods occur independently of transcription
2) transcription coordinates histone deacetylation at active promoters

Spatial transcriptomic clocks reveal cell proximity effects in brain ageing Nature - A spatially resolved single-cell transcriptomics map of the mouse brain at different ages reveals signatures of ageing, rejuvenation and disease, including ageing effects associated with T...

Thrilled to see this paper out!! 🧪

Spatial transcriptomics of brain aging and 'spatial aging clocks' identify cells that have pro-aging or pro-rejuvenating effects on their neighbors!

Huge CONGRATS to Eric Sun and all authors! Fantastic collaboration with @jameszou.bsky.social!

Wow. Fascinating work. I need to read carefully but I was wondering if infiltrated T cells have been reported in old human brain.

Controlling Transcription Elongation and Termination: More Than a Means to An End

As you make have seen, there is a special issue of JMB on "Controlling Transcription Elongation and Termination: More Than a Means to An End" curated by my colleague here at Pitt Karen Arndt and by Steve Buratowski from Harvard Medical School 🧪🧵 1/ www.sciencedirect.com/science/arti...

Our latest paper, a fantastic collaboration with the Mendell Lab, is out. Great work by Xiaoqiang Zhu and Victor Cruz. We uncover how tRNA structural features in the ribosomal P-site modulate co-translational mRNA decay by the CCR4-NOT complex. #RNAsky #RNAbiology #translation #ribosome #cryoEM 1/5

Nice to see all you chromatin & epigenetics aficionados here! As we build our network back up please repost details for our upcoming webinar this Friday!

We are delighted to welcome Emma Farley for her webinar 'Dependency Grammar of Developmental Enhancers' on November 22nd. Registration below 👇
