However, little or no ATF4 activation or mTOR suppression was detected upon OXPHOS inhibition in resistant cancer cells (CFPAC‐1, 786‐O, and SF126) under the same treatments (Figure 1G; Figure S1F, Supporting Information), suggesting very limited induction of cellular stress responses in these cancer cells upon OXPHOS inhibition. The gene discussed is MTOR; the disease is cancer.
