Mir-roring hypoxia in EGFR-TKI tolerance

Understanding the mechanisms by which tumour cells adapt or succumb to targeted therapies is crucial to improving cancer treatment. A study in this issue of Nature Metabolism demonstrates how microRNAs, metabolic pathways and pseudohypoxia play a major role in the drug tolerance to epidermal growth factor receptor (EGFR) inhibitors in lung adenocarcinoma.
