Deubiquitinating enzymes (DUBs) function in opposition to E3 ubiquitin ligases by removing ubiquitin from substrates to control protein and organelle homeostasis and responses to cellular stimuli. In this Review, Dewson et al. describe the many associations of DUBs with the hallmarks of cancer, with a view to identifying those DUBs most likely to impact cancer-associated phenotypes if targeted with selective inhibition.

Although tumour metabolism is well recognized as a key feature in cancer initiation and progression, little is known about metabolic reprogramming in patients. In this Review, Bartman et al. discuss stable-isotope tracing as a means to probe tumour metabolism in vivo and provide an overview of isotope labelling studies performed in patients with cancer.

In this Review, Swietach and colleagues discuss how the pH balance is dysregulated in tumours and how alterations in intracellular and extracellular pH affect tumour biology to accelerate disease progression, providing a rationale for therapeutic targeting of acid–base disturbances in cancer.

Adrenocortical carcinoma is a rare endocrine cancer with a dismal survival rate and limited therapeutic options. This Review outlines the recent advances that have been made in the understanding of the molecular basis of adrenocortical carcinoma and what this means for the diagnosis and treatment of patients with this cancer type.
