Happy to share that our preprint is now published at @embomolmed.org! We expanded on the benchmark of porcine ductal organoids by a pretty extensive proteomics dataset to compare organoids derived from different developmental stages of the pig #devbio #PancSky www.embopress.org/doi/full/10....

nice & very interesting. How does it relate to the ER stress in mild MODY10 variants that doesn't affect cysteines and db/db mice that have misfolded proinsulin? Are these special cases or misfolded proinsulin precipitate a cascade that spread?

LONP1 regulation of mitochondrial protein folding provides insight into beta cell failure in type 2 diabetes - Nature Metabolism LONP1, whose expression is downregulated in islets from donors with type 2 diabetes, is vital to mediate efficient mitochondrial protein folding, thus preventing proteotoxicity and promoting islet β c...

Type 2 diabetes is often considered a protein misfolding disease. But where are these toxic proteins found? 🤔

Interphase cell morphology defines the mode, symmetry, and outcome of mitosis During tissue formation, dynamic cell shape changes drive morphogenesis while asymmetric divisions create cellular diversity. We found that the shifts in cell morphology that shape tissues could conco...

What an elegant study showing that the mode and shape of cell division is defined by interphase morphology! This work suggests how cell fate and morphological asymmetries can be propagated via cell division in tissues.
