The graphs represent the rate of lactate production (mmol × l⁻¹ × optical density (OD)⁻¹; upper panel) and glucose consumption (mmol × l⁻¹ × OD⁻¹; lower panel) normalized to total cell content (OD) after 5 days of culture in 5 or 21% oxygen (gray column = 3 mM 3-OHB; black column = control). Each column represents mean ± SEM of four independent experiments
