DNAH8 and cancer: In K562 cancer cells, Ade increased ATP content to 57%, 57%, 85%, 82%, and 96% at 0.5, 1, 2, 4, and 8 mM levels, respectively, and oligomycin (Oli), an FoF1-ATPase inhibitor, almost abolished ATP production, but did not affect Ade-mediated ATP production in the absence of d-glucose in the culture medium (Fig. 1B).
