mTORC1-dependent control of Hedgehog signaling mediates nutrient-responsive licensing of intestinal stem cell differentiation

Gaia Fabris, Simon Biaudet, Atte Hallasaari, Tuuli Kirkinen, Kari Moisio, Krista Kokki, Simon Andersson, Pekka Katajisto, Ville Hietakangas

This study identifies an mTORC1-PWP1-Hedgehog circuit that links nutrient metabolism to intestinal stem cell differentiation in Drosophila, showing its role in aging and tissue renewal.

Evolutionary conservation and divergence of regional fructose-responsive gene regulation in the intestine

Marius R. Robciuc, Atte Hallasaari, Nicole Lamichane, Ville Hietakangas

This study examines how fructose-responsive gene regulation varies across intestinal regions in mice and fruit flies, finding conserved pathways and divergent metabolic responses.

Metabolic control of enteroendocrine cell fate through a redox state sensor CtBP

Bohdana M. Rovenko, Kari Moisio, Cornélia Biehler, Mykhailo Girych, Atte Hallasaari, Onur Deniz, Sarah Bluhm, Arto Viitanen, Krista Kokki, Gaia Fabris, Yi Yang, Valentin Cracan, Irene Miguel‐Aliaga, Ville Hietakangas

This study identifies CtBP as a redox state sensor that controls enteroendocrine cell fate in Drosophila by integrating metabolic signals with transcriptional regulation.
