Stress makes memories...epigenetically speaking!! A histone ubiquitylation “stress switch” lets environmental signals lock into heterochromatin, passing on epigenetic memories long after the stress is gone. Fantastic story! Congrats @grewalsh.bsky.social‬ @bharat-bhatt.bsky.social and team! 👏👏

We are delighted to welcome our newest faculty member, Sahana Holla (‪@sahanaholla.bsky.social‬). She is investigating the biological significance of 3D genome organization during development & disease, with an interdisciplinary approach combining genomics, proteomics, and advanced imaging.

So proud of you, @sahanaholla! Watching your journey has been such a joy. Wishing you all the best as you begin this exciting new chapter at TIFRH. They’re lucky to have you!

Thrilled to share that I’ve joined @tifrhyderabad.bsky.social as an Assistant Professor! Grateful to my mentors (esp @grewalsh.bsky.social and KN Balaji), colleagues, friends, family & EVERYONE who made this possible. Excited to explore Epigenetics & the 3D Genome with the brilliant minds in India!

What was that you said? You are looking for new #RNA research to read in the weekend? You are in luck! 📣 📣 Check out the new preprint from our lab!!!! 📣 📣 www.biorxiv.org/content/10.1...

AGO2 slicing of a domesticated retrotransposon is necessary for normal vasculature development

Argonaute (AGO) mediated slicing of RNA, also known as RNAi, is a highly conserved phenomenon that is evolutionarily linked to the repression of transposons and other repeats. Although RNAi is no long...
