COX7B and cancer: Although additional studies are required to fully elucidate the functional role of the COX7B gene, these scRNA‐seq results could offer a new transcriptome landscape of platinum‐resistance that provides valuable insights into chemosensitivity and cancer stemness at a single‐cell level.6, 11, 14, 15, 22, 47, 48, 49 Such single‐cell analyses will be instrumental in the design of new clinical diagnostic strategies.
