dc.description.abstractEnAerobic glycolysis is a hallmark of cancer development, but this dogma has been challenged by reports showing a key role of oxidative phosphorylation (OXPHOS) in cancer cell survival. It has been proposed that increased levels of intramitochondrial proteins in cancer cells are associated with high OXPHOS activity and increased sensitivity to OXPHOS inhibitors. However, the molecular mechanisms leading to the high expression of OXPHOS proteins in cancer cells remain unknown. Multiple proteomics studies have detected the ubiquitination of intramitochondrial proteins, suggesting the contribution of the ubiquitin system to the proteostatic regulation of OXPHOS proteins. Here, we identified the ubiquitin hydrolase OTUB1 as a regulator of the mitochondrial metabolic machinery essential for lung cancer cell survival. Mitochondria-localized OTUB1 modulates respiration by inhibiting K48-linked ubiquitination and turnover of OXPHOS proteins. An increase in OTUB1 expression is commonly observed in one-third of non-small-cell lung carcinomas and is associated with high OXPHOS signatures. Moreover, OTUB1 expression highly correlates with the sensitivity of lung cancer cells to mitochondrial inhibitors.
