Excited to share our new paper, now published in Nature Cell Biology! 🎉 We asked a fundamental question in cell biology: How do cells maintain polarity while migrating? Especially how do cancer cells navigate confined spaces? www.nature.com/articles/s41556-026-01981-1

CD44 restricts EGFR mobility to polarize cytoskeletal signalling modules driving bleb-based migration - Nature Cell Biology

Jha et al. show that the transmembrane protein CD44 restricts EGFR mobility to maintain an EGFR–PI3K–Rac gradient during bleb-based cell migration.

“move from preprint to peer-reviewed publication leaves the central claims of most abstracts intact, indicating preprints are a reliable source…papers that were never posted as preprints were retracted at roughly twice the rate of those that were…” www.biorxiv.org/content/10.6...

Preprints now disseminate a large share of biomedical research before peer review. Because they have not yet passed peer review, some scientists regard preprint claims as unverified or potentially unr...

New publication alert! We use theory and experiment to demonstrate that glassy adhesion dynamics can predict anomalous migration on viscoelastic substrates. Grateful to have worked with Vivek Sharma, Ze Gong, Ovijit Chaudhuri, and Vivek B Shenoy 🙏 ! www.nature.com/articles/s41...

Glassy adhesion dynamics govern transitions between sub-diffusive and super-diffusive cancer cell migration on viscoelastic substrates - Nature Communications

This study introduces glassy adhesion dynamics within a motor–clutch framework, revealing the mechanism by which cellular and extracellular timescales interplay and govern anomalous cancer cell migrat...

Preprint alert! Excited to share this manuscript from my PhD which aims to answer an age-old question. Does size matter? For fat cells, or adipocytes, the answer seems to be yes. We found that larger adipocytes promote aggressive behavior in breast cancer cells. 1/5 www.biorxiv.org/content/10.1...
