So happy our review is finally out in @natcancer.nature.com! Many glycans were mistreated in the making of the figures, although these were all caught by my co-authors, the proper glycobiologists #glycotime

Why cancer can come back years later — and how to stop it
Researchers are targeting dormant tumour cells that might explain why some cancers reappear long after successful treatment.

🚀New pre-print from the lab, led by PhD candidate Xiaolin Dong! www.biorxiv.org/content/10.6... In this study, we uncovered crosstalk between mucin-type O-glycans and HSPGs, showing that truncated O-GalNAc glycans destabilize proteoglycans, impair FGF signaling, & disrupt chondrogenesis. #glycotime

Comprehensive experiments in pre-clinical models and clinical data analysis demonstrate that dormancy creates a unique window of opportunity to deplete minimal residual disease and delay recurrence. Congratulations to all the authors on this important body of work!

As a budding scientist, the idea that form follows function led me to a career studying developmental biology and how these principles are distorted in cancer. Excited to share this preprint reporting a surprising transdifferentiation of breast cancer cells unlocked by dormancy. Link below:

For those of you that prefer feeds over following, I've figured out how to convert starter packs into lists, so you can get your glyco fix as a feed. If you're on the starter pack, you're on the list, and anyone new on the starter pack will get added to the feed!
