MCT1 activity defines an aggressive metabolic phenotype and therapeutic target in non-small cell lung cancer

Lactate uptake through monocarboxylate transporter 1 (MCT1) is associated with aggressive disease in non-small cell lung cancer (NSCLC), but how lactate transport supports tumor metabolism remains incompletely understood. Integrating stable isotope tracing, metabolomics, and transcriptomics across patient tumors, anima...

Loss of the mitochondrial SAM transporter reveals a lipoylation-dependent metabolic vulnerability in the postnatal heart

The neonatal heart experiences rapid metabolic growth after birth to meet increasing energetic and biosynthetic demands. How mitochondrial cofactor availability limits this transition remains unclear. Here, we demonstrate that mitochondrial S-adenosylmethionine (mitoSAM) import through SLC25A26 becomes limiting shortly...
