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

Dylan Ryan
The Tricarboxylic Acid (TCA) cycle is arguably the most critical metabolic cycle in physiology and exists as an essential interface coordinating cellular metabolism, bioenergetics, and redox homeostasis. Despite decades of research, a comprehensive investigation into the consequences of TCA cycle dysfunction remains elusive. Here, we targeted two TCA cycle enzymes, fumarate hydratase (FH), using an FH inhibitor (FHIN-1), and succinate dehydrogenase (SDH), using two inhibitors Atpenin A5 (AA5) and thenoyltrifluoroacetone (TTFA), and combined transcriptomics, and...
