Haem oxygenase is synthetically lethal with the tumour suppressor fumarate hydratase

C Frezza, L Zheng, O Folger, KN Rajagopalan… - Nature, 2011 - nature.com
Fumarate hydratase (FH) is an enzyme of the tricarboxylic acid cycle (TCA cycle) that
catalyses the hydration of fumarate into malate. Germline mutations of FH are responsible for …

Ischaemic accumulation of succinate controls reperfusion injury through mitochondrial ROS

…, MJ Shattock, AJ Robinson, LM Work, C Frezza… - Nature, 2014 - nature.com
Ischaemia-reperfusion injury occurs when the blood supply to an organ is disrupted and then
restored, and underlies many disorders, notably heart attack and stroke. While reperfusion …

Fumarate is an epigenetic modifier that elicits epithelial-to-mesenchymal transition

…, ER Maher, PH Maxwell, J Saez-Rodriguez, C Frezza - Nature, 2016 - nature.com
Mutations of the tricarboxylic acid cycle enzyme fumarate hydratase cause hereditary
leiomyomatosis and renal cell cancer 1 . Fumarate hydratase-deficient renal cancers are highly …

Crosstalk between mechanotransduction and metabolism

P Romani, L Valcarcel-Jimenez, C Frezza… - … Reviews Molecular Cell …, 2021 - nature.com
Mechanical forces shape cells and tissues during development and adult homeostasis. In
addition, they also signal to cells via mechanotransduction pathways to control cell proliferation…

Coupling Krebs cycle metabolites to signalling in immunity and cancer

DG Ryan, MP Murphy, C Frezza, HA Prag… - Nature …, 2019 - nature.com
Metabolic reprogramming has become a key focus for both immunologists and cancer biologists,
with exciting advances providing new insights into the mechanisms underlying disease…

Organelle isolation: functional mitochondria from mouse liver, muscle and cultured filroblasts

C Frezza, S Cipolat, L Scorrano - Nature protocols, 2007 - nature.com
Mitochondria participate in key metabolic reactions of the cell and regulate crucial signaling
pathways including apoptosis. Although several approaches are available to study …

[HTML][HTML] OPA1 controls apoptotic cristae remodeling independently from mitochondrial fusion

C Frezza, S Cipolat, OM De Brito, M Micaroni… - Cell, 2006 - cell.com
Mitochondria amplify activation of caspases during apoptosis by releasing cytochrome c and
other cofactors. This is accompanied by fragmentation of the organelle and remodeling of …

[PDF][PDF] Succinate dehydrogenase supports metabolic repurposing of mitochondria to drive inflammatory macrophages

…, HT Jacobs, M Szibor, RJ Xavier, T Braun, C Frezza… - Cell, 2016 - cell.com
Activated macrophages undergo metabolic reprogramming, which drives their pro-inflammatory
phenotype, but the mechanistic basis for this remains obscure. Here, we demonstrate …

Itaconate is an anti-inflammatory metabolite that activates Nrf2 via alkylation of KEAP1

…, ST Caldwell, ERS Kunji, ET Chouchani, C Frezza… - Nature, 2018 - nature.com
The endogenous metabolite itaconate has recently emerged as a regulator of macrophage
function, but its precise mechanism of action remains poorly understood 1 , 2 , 3 . Here we …

[HTML][HTML] Mitochondrial cristae shape determines respiratory chain supercomplexes assembly and respiratory efficiency

S Cogliati, C Frezza, ME Soriano, T Varanita… - Cell, 2013 - cell.com
Respiratory chain complexes assemble into functional quaternary structures called
supercomplexes (RCS) within the folds of the inner mitochondrial membrane, or cristae. Here, we …
