CLA-induced unidirectional ²²Na⁺ (○) and ⁸⁶Rb⁺ (•) uptake in nulled isotonic medium containing 0.5 μM CLA. Cells were preincubated in ouabain (1 mM)-containing isotonic media for 90 min. At time 0 cells were placed in nulled isotonic media + 500 nM CLA, and samples were removed at the times indicated to measure ²²Na⁺ and ⁸⁶Rb⁺ unidirectional uptake. Similar results were obtained in 3 experiments.
