Determining uric acid concentrations. Cells and spheroids were exposed to different uric acid concentrations. AncUOX positive cells or spheroids were able to oxidize uric acid. Both wild-type and control (Puro/RFP only) cells were unable to oxidize uric acid. a–d, Huh monolayer. e–h, Huh spheroids. Values of uric acid are means ± SEM of three replicates. *p < 0.05, **p < 0.01, and ***p < 0.005.
