Nitrogen partitioning between branched-chain amino acids and urea cycle enzymes sustains renal cancer progression

M. Sciacovelli, A. Dugourd, L. Valcarcel Jimenez, M. Yang, E. Nikitopoulou, A. S. Costa, L. Tronci, V. Caraffini, P. Rodrigues, C. Schmidt, D. G. Ryan, T. Young, V. Zecchini, S. H. Rossi, C. Massie, , C. Frezza

This study identifies metabolic reprogramming in renal cancer cells, showing how branched-chain amino acid catabolism and urea cycle enzymes support tumor progression and metastasis.

Nrf2 is a central regulator of the metabolic landscape in macrophages and finetunes their inflammatory response

D. G. Ryan, E. V. Knatko, A. Casey, J. L. Hukelmann, A. J. Brenes, S. Dayalan Naidu, M. Higgins, L. Tronci, E. Nikitopoulou, L. A. O'Neill, A. I. Lamond, A. Y. Abramov, D. A. Cantrell, M. P. Murphy, A. T. Dinkova-Kostova

This study shows Nrf2 regulates macrophage metabolism, redox balance, and inflammatory responses, with 4-OI modulating these effects through Nrf2.

Disruption of the TCA cycle reveals an ATF4-dependent integration of redox and amino acid metabolism

D. G. Ryan, M. Yang, H. A. Prag, G. R. Blanco, E. Nikitopoulou, M. Segarra-Mondejar, C. A. Powell, T. Young, N. Burger, J. L. Miljkovic, M. Minczuk, M. P. Murphy, A. Von Kriegsheim, C. Frezza

This study investigates the effects of TCA cycle inhibition on redox and amino acid metabolism, revealing ATF4-dependent metabolic rewiring and distinct responses between FH and SDH inhibition.
