Fig. 1: The essentiality of mitochondrial genes in tumour cells.

a Schematic diagram shows our analysis pathway for using the Achilles cancer dependency map (DepMap) gene essentiality data. b Pie charts show the percentage of common essential genes (shown in yellow) among mitochondrially expressed genes (left chart), and among all genes screened (right chart) in (a). Other (non-common essential) genes (shown in blue). c List of common essential mitochondrially expressed genes identified in (a), grouped by functional annotation. (*) indicates genes with multiple functions.
