It is a great pleasure to share our most recent work on ‘rejuvenating’ nuclear speckles to ameliorate proteinopaties such as Tauopathy and retinitis pigmentosa. It is my first publication that is not related to biological rhythms and I am very excited to nature.com/articles/s41467-0…

SON-dependent nuclear speckle rehabilitation alleviates proteinopathies

Nature Communications - Here the authors show that rehabilitating nuclear speckles, membraneless organelles involved in mRNA processing and gene regulation, can boost protein quality control and...

What if a tiny nuclear structure helps determine whether neurons survive or degenerate? Our new Trends in Neurosciences review explores how nuclear speckles—dynamic nuclear condensates once thought to be passive splicing hubs—coordinate RNA metabolism, stress responses,

I am so sad to hear the passing of Dr. Bert O’Malley today. He has been a great mentor for me and has always been my inspiration for pursuing science. The world has lost a great scientist and mentor today.

SWING domains prime chromatin for nuclear body–mediated gene regulation

Nuclear speckles have long been recognized as RNA-rich nuclear bodies, yet their role in genome organization and gene regulation remains incompletely understood. Using a rapid dTAG-mediated degrada...

Glad to see this paper finally out. It was a fascinating story when it first came out as a preprint a few years back.

Perhaps our boldest hypothesis… we propose a model for RNA Structural Memory propagation @NatureCellBio, where RNA conformation is reshaped by stress, locked by RBPs, copied prion-like in condensates & passed across generations—all without altering DNA.🧵 rdcu.be/eBwPJ
