TIMM50 and breast cancer: Several lines of evidence support these observations: TIMM50 stable silencing in human breast cancer cell lines suppresses cell proliferation (Gao et al, 2016); Ttm50‐depleted Drosophila has a diminutive body due to a reduction in both size and number of cells caused by cell growth and proliferation defects (Sugiyama et al, 2007); and Tim50 knock‐down in T. brucei produces a slow growth phenotype (Duncan et al, 2013).
